RefreshinghinggSimplicityyWith more than 95% of all manufactured goods touched by the business ofchemistry,1 our world increasingly depends on chemistry to fuel humanity’ssocial progress, defined as “the capacity of a society to meet the basic human needs of its citizens.”2 Chemistry enables advances across virtually all
aspects of daily life, like communications, transportation, housing, nutrition,and energy; to enhance the quality of people’s lives and help them reach
their full potential. At the same time, science tells us that we must minimize
the planetary burdens that human activities can create, from greenhousegas (GHG) emissions to resource depletion to waste generation, so we don’tcompromise the ability of future generations to meet their own needs.

member states unanimously adopted the Sustainable Development Goals(SDGs) in 20153 as “the blueprint for achieving a better and more sustainenced, they are the logical framework by which to identify opportunities for
Chemours to help create a better world through the power of our chemistry.
Therefore, one of our CRC goals, Sustainable Offerings, seeks to ensurethat 50% or more of our revenue comes from offerings that make a specificcontribution to the UN SDGs.5

EVOLVE 2030: Sustainable Offerings Assessment Method3Chemours' EVOLVE 2030 is the method by which we assess our productportfolio across our businesses to qualify and quantify revenue that makesa specific contribution to the UN SDGs and measure our progress towardachieving this goal. More importantly, the outputs of EVOLVE 2030 assessments inform our decision-making by identifying ways that we can maximize
our products’ societal contributions while minimizing their planetary burdens.
This includes providing assessment insights into our innovation management
process. Simply put, EVOLVE 2030 helps us to transform our portfolio for asustainable future.
As Chemours announced our CRC goals in 2018, the World BusinessCouncil for Sustainable Development (WBCSD) published the Chemical
Industry Methodology for Portfolio Sustainability Assessments (PSA),6
which became the basis for EVOLVE 2030. Because the world and its
expectations are constantly evolving, we are, too. Version 2 of EVOLVE
2030 incorporates assessment of product and packaging material
circularity, as well as lessons we learned from 2020 to 2024.
Aligned with the WBCSD PSA, our unit of analysis is a Product—Application
Combination (PAC), which allows the combined consideration of a product’s
benefits and burden through its life cycle. Fundamental to our approach isthe estimation of each PAC’s Contribution to the UN SDGs and the PAC’s“Imprint”—or net impact on society and the environment.
• Contribution—Each PAC is evaluated for its contribution to the Targets
and Indicators associated with the 17 UN SDGs. Contribution is measured in two dimensions:		1. S
 ignificance, indicates the relative role of the Chemours’ productin the complete solution helping to meet the SDG; and		

2. Magnitude,indicates the relative; and importance of the solution
for achieving the SDG.

• Imprint—Aligned with the WBCSD PSA, the “Imprint” is an approachto create an understanding of the PAC’s net impact on society and theenvironment. The Imprint includes several attributes with direct links

to other Chemours CRC goals, (e.g., impact on climate change, landfill
intensity, and emissions of fluorinated organic chemicals to air andwater) as well as additional attributes covering topics such as risk tohuman health and public sentiment.
EVOLVE 2030: Sustainable Offerings Assessment Method4

In combination, a PAC’s Imprint and Contribution scores determine if the
PAC makes a “specific contribution” and if its revenue qualifies to advancethe Sustainable Offerings 2030 CRC goal.
To effect change, the outcomes of PAC evaluations are integrated intobusiness processes to provide insights and options for consideration indecision-making:• Define objective: Design chemical products and processes that maximize
societal benefits while minimizing societal/planetary burden in the SDG
framework• Measure indicators: By EVOLVE 2030 method• Develop and design alternatives: In collaboration with or support ofbusiness and functional teams through various business processes; someexamples include new product development, manufacturing processchanges, capital investment, and procurement of more sustainable raw
materials or energy• Verify design: By EVOLVE 2030 method in re-evaluations, either triggered by time (i.e., 5-year cycle) or by an event (e.g., process improvement,change in regulations, new scientific results)
In this way, we intend to help guide investments in sustainable solutions
that are manufactured and used responsibly throughout their life cycle,
thereby reshaping our portfolio to advance our company vision.

EVOLVE 2030: Sustainable Offerings Assessment Method5

2. Principles
and Scope

As stated above, the objective of creating this method is to inform ourdecisions with sustainability information and insights —decisions about
our product portfolio, our investments in innovation, and how we deploy our
resources, with the intent of reshaping our portfolio to support achieving
a better future for people globally, our shared planet, and our company. To
effectively achieve this objective, our method must strive for completeness,accuracy, reproducibility, efficiency, speed, and balance.
For objectivity, EVOLVE 2030 is constructed to be data-driven and science-based, relying on rubrics with clear criteria for scoring. Because data
quality can vary greatly, we identify information gaps, work to fill them,and account for uncertainty and data quality in our analyses. In addition,
EVOLVE 2030 seeks to be holistic in its considerations because basing
decisions on an incomplete view of the system as a whole, like driving while
only looking out the front windshield, will almost certainly lead to regrettable decisions and unintended consequences.
At the same time, speed is critically important in addressing some of thebiggest global challenges we face, and an effective method must consider this urgency. EVOLVE 2030 is designed to deliver insightful analyses
as quickly as possible by utilizing existing data sources and outputs fromexisting processes, avoiding redundancies, and focusing efforts on what isnecessary for decision-making. For example, in comparing energy efficiency, if an analysis concluded that two options under consideration require
20 and 40 kilowatt-hour (KWh) to perform the same function, it’s not likely
one would need to refine the analysis to 20.3 and 40.7 KWh to reach arobust decision. Therefore, to avoid analysis paralysis, EVOLVE 2030
pursues the necessary and not the minutia. In its tiered approach, EVOLVE
2030 intends to provide the framework to quickly reach sound conclusions or, if justified, dedicate the appropriate level of effort to refining theanalysis necessary to reach a well-informed decision. In this way, we intend
to efficiently steer decisions to make the biggest positive contributions tosociety as quickly as possible with available resources.
We also recognize that bias is inevitable. To minimize bias, we developed
EVOLVE 2030 in partnership with Anthesis Group, a global sustainability
advisor. Additionally, Anthesis has participated in all PAC evaluations toprovide expertise across subject matters and broad perspectives acrosscompanies and industries. In 2019, after completing our pilots, we obtained third-party assurance from Lloyd’s Register Quality Assurance Ltd(LRQA). In 2024, with the majority of our portfolio reviewed and the second

EVOLVE 2030: Sustainable Offerings Assessment Method6version of EVOLVE 2030 completed, we received a new limited assurance
statement from LRQA.
As mentioned above, because change is certain and seemingly accelerating, our approach to this method is one of flexibility and constant improvement. By quickly establishing our method in 2019, we were able to learnorganically from our experiences while making progress. Furthermore, we
conducted an empirical study to test the reproducibility of our evaluations.
The knowledge and insights we gained led to improvements in our PAC
evaluation processes, instructions, and documentation. These and the additional procedures to evaluate product and packaging material circularity areincluded below. By relentlessly pursuing ways to become more accurate,
reproducible, efficient, and faster, we strive to evolve and stay relevant inthis constantly changing world. Therefore, this version of EVOLVE 2030 isa single frame in the motion picture of time.
The consideration of PAC Contribution and Imprint often requires comparisons of alternatives. For pragmatic reasons, this method is not intended
to consider comparisons outside of current societal norms. For example,
society has decided to have air conditioning (e.g., heat pumps) as a climate
adaptation option and refrigeration to minimize food loss and waste in theface of deteriorating food security from climate change and geopoliticalconflicts. So alternative air conditioning refrigerant options may be assessed, but we are not assessing the option of using a fan or opening awindow as a means to stay cool, nor will we consider not using refrigeration
as a means of preserving food and pharmaceuticals.
The EVOLVE 2030 method applies to existing revenue-generating PACs
and PACs in Research and Development projects. Additionally, where
Chemours has a controlling interest (>50%), a joint venture’s portfolio is in
scope for evaluation using EVOLVE 2030. The footprint of internal product transfers and site-limited intermediates are included in the evaluationsof the finished products. As general guidance, products whose revenue
contributes to Chemours total net sales (i.e., the denominator of our 50%goal) should be considered in-scope for evaluation (i.e., the numerator). The
EVOLVE 2030 method can also be applied within Chemours’ mergers andacquisitions activities.

3. General
Requirements

3.1 Business Process Overview
The PAC evaluation process consists of three stages (see Figure 1):
1. Data Collection & Validation—The objective of the first stage is tocollect the necessary data, including understanding substances’ mass
partitioning and fate through the life cycle. For efficiency throughmaximizing first-pass yield, all information needed for defining PACs, alternatives, functional units, as well as for assessing each PAC’s Imprint
attributes and contributions to SDG Targets, should be validated.
2. Analysis & Scoring—Each PAC is scored for its specific contribution to
the SDG Targets (Contribution score) and its net environmental, health,and social impact, assessed by the PAC’s aggregated Imprint attributes(see Figure 2). Details on the scoring methodologies are described in
section 3.2. These scores determine the PAC’s qualification for making
a specific contribution and whether its revenue will count towards theSustainable Offerings goal. In addition, opportunities to increase contribution or improve net impact are identified and prioritized.
3. Align & Summarize—The final stage of the PAC evaluation process
is to ensure alignment regarding specific improvement actions to betaken and to summarize the findings of the EVOLVE 2030 evaluationfor effectively informing decisions in the appropriate processes orforums to guide Chemours business strategies and to meet its 2030
Sustainable Offerings goal.
Importantly, this collaborative process results in collectively owned outcomes
and commitments to take improvement actions.
As depicted by the improvement cycle diagram above, we commit to refresh
our evaluations as a part of this five-year cycle. However, additional re-evaluations will be triggered by significant changes, such as demonstrated
manufacturing process improvements or the development of macro trends
that may result in changes in Contribution and/or Imprint scoring or present new opportunities to enhance the sustainability of our offerings. New
research and development projects will trigger evaluations, as can merger
and acquisition activities.

3.2.1 Imprint Attributes Overview
The term “Imprint” represents a PAC’s net impact on society and the environment. Any PAC’s Imprint is represented by multiple attributes, whose
scope and benchmarks for scoring are shown in Figure 2.

As noted in Figure 2, some attributes are judged against an absolute
standard. For example, the manufacturing intensities (Attributes 1a, 2,
and 3a) of the PAC under evaluation are compared to the Chemours CRC
goal target intensities. Similarly, human health and environmental risks areassessed based on chemical properties, hazards, and exposures, with noregard to those of the alternative to which this PAC is compared. In contrast, the climate impact through the life cycle (Attribute 3b) score is basedon the performance of the PAC relative to an alternative.
For Attributes 1-3, the overarching design principle is to be consistent withthe definitions, calculations, and scope of the CRC Environmental Leadership goals. Figure 3 is a graphical representation of the evaluation process
for these attributes.

3.2.1.1 Attribute 1: Landfill Volume Intensity
Attribute (1a) includes both hazardous and non-hazardous waste generated
during the entire product manufacturing process. PACs are assessed for
performance against our goal to reduce landfill intensity by 70% by 2030.7
To better understand and improve the circularity of our products’ packaging
material, we added Attribute (1b) to this version of EVOLVE 2030. Where
Attribute (1a) aims to minimize the landfill intensity of our operations,
Attribute (1b) seeks to measure and reduce waste resulting from Chemours
products’ packaging. Analogous to Attribute (3b), Attribute (1b) expands thescope to consider downstream impacts.

3.2.1.4 Attribute 4: Material Circularity
This attribute has been added to the second version of EVOLVE 2030 in
response to increasing concerns about resource extraction and depletion,
as well as waste generation and pollution. As EVOLVE 2030 was developed within the PSA framework, this attribute similarly benefits from theknowledge and experiences of those who created the WBCSD CircularTransition Indicators (CTI) framework.9

Annually, the Circularity Gap Report10 estimates the circularity of the global
economy, which we have chosen to use as the dynamic benchmark against
which we will score the material circularity of PACs.
Scoring rubric:+2

The PAC’s material circularity is greater than two times the circularityof the global economy+1

The PAC’s material circularity is greater than the circularity of the
global economy, but below twice that number

The PAC’s material circularity is above a 5% threshold but less thanthe circularity of the global economy, or the PAC’s material circularity is<5% but it substantially improves the system’s circularity-1

The PAC’s material circularity is <5% with no substantial positive
impact on the system, but concrete improvement plans are in place toreach the 5% threshold within 3 years-2

The PAC’s material circularity is <5% with no substantial positive
impact on the system and no improvement plans, or the PAC createsa significant technical barrier to system circularity

3.2.1.5 Attribute 5: Human Health Risk
The human health assessment focuses on the product and its specific use
as defined by the PAC. Toxicologically important impurities are included
within the scope of this assessment. Please note that the human health risk
during the manufacture of our product is not included in the scope of thisassessment. Risk to workers is assessed and addressed by Environment,

The PAC contains substances that either do not break down (otherthan those categorized in score 0) or are expected to cause harm tolife in the relevant compartment(s) over time

3.2.1.7 Attribute 7: Social Impact
The Social Impact Attribute focuses on the holistic impact of the PAC
through its life cycle (cradle to grave). This attribute intends to capture positive or negative social impacts associated with the PAC (when compared tothe alternative that would be used if the PAC did not exist) that are not captured by other Imprint attributes, e.g., the social benefit of reduced carbon
emissions is assumed to be captured in Attribute (3b), Life cycle impact on
climate and should not be considered when scoring this attribute.
The social impact assessment was developed to align with the six principlesof the WBCSD Social Life Cycle Metrics for Chemical Products (Relevance,
Completeness, Consistency, Transparency, Accuracy and Feasibility).12
However, this assessment is qualitative and is based upon a review ofexisting data and information by a cross-functional team at Chemours. As astarting point for the assessment, this team reviews the potential impact onworkers, local communities, and consumers within the context of relevant
12 World Business Council for
Sustainable Development,
Social Life Cycle Metrics for
Chemical Productssocial topics identified in the WBCSD Social Life Cycle Metrics for Chemical Products. These social topics cover a broad range of issues, which fall
into the following overarching categories: basic rights and needs, employment, health and safety, skills and knowledge, and well-being. In addition to

EVOLVE 2030: Sustainable Offerings Assessment Method

16consideration of the topics identified by WBCSD, the team also considers
other negative and positive social impacts that may be unique to the PAC.
Based on the topics identified, the team then scores the social impact
based on the type of impact associated with the PAC, using the following
definitions:
Note that the examples presented below are provided for illustrative
purposes and are not intended to be exhaustive.
• Life-changing positive impact: Alters the courses of people’s lives.
Examples:– Provide means (e.g., training, education, financing, jobs) for people
to move out of poverty– Reduce undernourishment13 and stunting14– Reduce death rate
– Increase availability of potable water– Provides access to electricity• Life improving: Improves the quality of life. Examples:– Increase the standard of living– Increase access to healthy diets– Ease pain and suffering from health issues– Comfort to the extent of preventing health issues– Improve the quality of potable water– Improves the reliability of electrical supply• Convenience/aesthetics: Expedience or provides a positive psychologicalresponse. Examples:– Entertainment or recreational end-uses (non-drug)– “Want” versus “need”• Possible to cause negative social impacts: Possible under unusual or unexpected scenarios–unintended uses or inappropriately used.

The justification for the attribute score for each PAC is documented by theassessment team, along with any assumptions and supporting evidence asappropriate.
Scoring Rubric:+2

Outstanding performance—PAC results in life changing positive impact at a local, national or global scale or life improving positive impact
at a global scale. Any potential or likely negative social impact disqualifies the PAC for a +2 score.

+1

Good performance—PAC results in life improving positive impact at
the local or national scale, and any potential or likely negative social
impacts are effectively mitigated0Standard performance—PAC impact is restricted to improved convenience for consumer and/or improved aesthetics, but social impact islimited or too small to evaluate.

-1

Inadequate performance—PAC has the potential to create negativesocial impacts at a local scale which supersede any positive social
impacts.

-2

Unacceptable performance—PAC has the potential to create negative social impacts at a national or global scale, which supersede any
positive social impacts, or PAC is likely to have a negative social impact
at a local, national, or global scale which supersede any positive social
impacts.

As noted in the WBCSD PSA, many traditional assessment tools (e.g., environmental and social life cycle assessments) don’t consider market perception andregulatory developments when assessing product and company-level risks.
Unlike other attributes within the EVOLVE 2030 assessment, Attribute 8
is based on stakeholder impressions of environmental and social impacts,
which may or may not be based on scientific evidence.

EVOLVE 2030: Sustainable Offerings Assessment Method

Nevertheless, these perceptions can lead to significant business risks andrequire careful consideration when evaluating PACs’ contributions to the
UN SDGs. Therefore, we have taken an approach that is consistent with the
WBCSD PSA guidance.
The evaluation methodology for Stakeholder Sentiment is divided into two
attributes:• 8a. Regulatory Activity (Current and potential regulatory scenarios)
This attribute is assessed by conducting a search using subscription-based
third-party tools to check for current or proposed regulatory bans or restrictions that may be relevant to the PAC, as input to score according to therubric below.
Scoring Rubric:+2

No component is currently banned or restricted under industrial chemical management regulations and is not associated with any proposedbans and/or restrictions.

+1

No component is currently banned or restricted under industrial chemical management regulations, but at least one component is associatedwith proposed bans and/or restrictions.

0

One or more components are currently banned or restricted underindustrial chemical management regulations but there are reasonableindications that the ban or restriction could be removed or one or morecomponents are proposed for regulations, but there are reasonableindications that the ban or restriction would not come into effect.

-1

An intentional component is banned or restricted in one jurisdiction.

-2

Intentional component is banned or restricted in an influential jurisdiction or in multiple jurisdictions globally or is considered a Substance ofVery High Concern (SVHC) or if any component is classified as Group I
by IARC.

Components include intentional, unintentional, and degradants.
While the focus is on industrial chemical management regulations, other regulations relevantto the PAC will be considered when appropriate.

EVOLVE 2030: Sustainable Offerings Assessment Method19• 8b. Public Sentiments
This attribute is assessed by surveying the sentiments of aspects suchas communities, direct customers, value chains, media, and considers thescores of all other attributes:
Scoring Rubric:+2

No known perception issues and scores above neutral in all other attributes (i.e., unlikely to have perception issues based on other attributes)+1

No known perception issues BUT scores at or below neutral in one ormore other attributes (i.e., possibility of other attribute causing perception issue)0

No perception issues identified for the PAC, but it includes consumer
use and/or contact-1

Localized or limited public concerns identified or PAC includes consumer contact use and issues exist for adjacent PAC(s)-2Severe or widespread concerns identified

3.2.2 UN SDG Contribution Scoring and Rubrics
The Contribution score rates a PAC’s contributions to the UN SDGs at
the Target level with consideration of Indicators for greater specificity.
It is measured in terms of Significance, how important the product is to
the Solution’s contribution to an SDG, and Magnitude, how important the
Solution’s contribution is to achieve an SDG, as compared to an appropriate
reference (e.g., “Business as Usual” (BAU) or best demonstrated alternativetechnology). Adapted from WBCSD guidance, Significance and Magnitude
shall be scored on a scale from 0 to 5.15
When considering contributions to SDG Targets, the Subject Matter Experts (SMEs), Product Steward, and relevant experts from the Business
whose PAC is under evaluation are encouraged to identify as many SDGs as
possible where PACs may contribute. The entire hierarchy of SDGs (Goals,

A breakdown of scoring for
Significance and Magnitude is provided in the following rubrics.

The product is part of the key component andits properties and functions are essential for
enabling positive SDG contribution of the PAC.
Known practical alternatives would lead to verysignificant negative impacts in environmental

The Significance and Magnitude scores are multiplied to calculate the Contribution score. A score equal to or above the threshold of six (6) indicatesthat the PAC meets one of the criteria for making a specific contribution
to an SDG. However, the contribution score alone does not indicate if a
PAC’s revenue may be counted as a specific contribution towards our 50%
Sustainable Offerings goal. The PAC must also earn a non-negative overall
Imprint score.
Each PAC may contribute to several UN SDGs. When multiple SDG Targets
are considered, the highest score for one SDG Target will be considered as

SDG Targets shall not be summed to achieve an overall higher Contribution
score.

EVOLVE 2030: Sustainable Offerings Assessment Method22

3.2.3 Imprint Scoring and Aggregation
To allow plotting on a simple matrix, individual PAC Imprint attribute scores(as per section 3.2.1) are aggregated to an overall score using simple summation. We chose to use simple summation because developing weighting
factors is complex, likely subjective, and often controversial. The intentionof this exercise is to surface opportunities to improve, amplify strengths,
and, where justified, further examine and refine our analyses. We feel thiscan be accomplished without the need for weighting factors.
Each individual Imprint attribute score of -2 must be reviewed to bringgreater focus on improvement opportunities.
3.2.4 EVOLVE 2030 Matrix
As shown in Figure 4, the Contribution and Imprint scores can be plotted on
a 2x2 matrix to identify in which quadrant each individual PAC is located. For
PACs located in the upper right quadrant (quadrant A in Figure 4), their Imprint
and highest single UN SDG Target Contribution scores meet the requirements
for specific contribution, and their revenue may be counted toward the 50%
Sustainable Offerings goal. Revenue of PACs located in quadrants B, C, and D
do not count towards the 50% Sustainable Offerings goal.

EVOLVE 2030: Sustainable Offerings Assessment Method23

Our intention is to improve the Imprint scores (i.e., over time, migrate PACs
from left to right on the EVOLVE 2030 matrix); even for those in quadrants
A and B, there are opportunities. As mentioned above, Imprints attributeswith scores of -2, along with PACs in quadrants C and D, will command
greater attention for improvement.

3.3 Summarize and Report
3.3.1 PAC Summary
A key output of the PAC evaluation process is the PAC Summary. Generated for each individual PAC, the summary will include an overview of the
PAC (including PAC definition, alternative considered in the PAC evaluation,functional unit, and PAC revenue), its Imprint attributes scores, and its Contribution scores, along with component Significance and Magnitude scores.
Perhaps most importantly, this summary includes a list of opportunities for
improvement. The PAC summaries will inform the strategy for progressing
toward achieving the Sustainable Offerings CRC goal, and inform businessdecisions in areas such as investments in product development, application
development, process improvements, mergers and acquisitions, and portfolio management. The target audience includes product managers, market
managers, technology engineers, scientists, managers, and other appropriate stakeholders within each business.

EVOLVE 2030: Sustainable Offerings Assessment Method24

4. High-levelscreening

As noted in Section 3.1, the in-depth evaluation of PACs described above
requires the participation of more than a half dozen business roles, inaddition to experts in subjects like toxicology, risk assessment, life cycle
analysis, regulatory data, compositional data, etc. For PACs whose risks
are apparent, the investment of thousands of person-hours to fully evaluate
a PAC will produce few, if any, additional insights, making the work hard tojustify.
To focus limited expert resources on efforts that generate greater societal
benefits, we use high-level screening to identify PACs whose most material
improvement opportunities can be identified without using the full extent
of evaluations described in Section 3.2. Two conditions apply to high-levelscreened PACs:
1. The revenue of these PACs may not be counted toward the 50%
Sustainable Offerings goal; and2. The known material improvement opportunities must be discussed with the aim of formulating recommendations that lead toaction, analogous to -2 scores described in Section 3.2.3

EVOLVE 2030: Sustainable Offerings Assessment Method25

5. Management
Approach

EVOLVE 2030 is substantially integrated into many, if not all, functions
across Chemours as we transform our offerings to meet societal needs anddeliver those offerings responsibly.
The EVOLVE 2030 PAC evaluation outcomes guide decision-making in theappropriate business processes and forums to shape and improve Chemours
business strategies and to meet our Sustainable Offerings goal by 2030.
Innovation is critical to the long-term success of our company and our ability
to increasingly contribute to the SDGs. Therefore, in addition to our existing
portfolio of offerings, the EVOLVE 2030 methodology is incorporated into
the business processes, which have the potential to reshape our portfolio,
including our new product and application development processes. We update PAC evaluations on a specific frequency or as material changes occur
to a product or its application. Using EVOLVE 2030, we will drive rapid
progress through innovation, collaboration, and partnership that can provide
unmatched solutions to achieve the SDGs.

6. Definitions

Absolute –The benchmarks against which the PAC is scored are set byinvariant historical values or intrinsic properties.
Alternative –To be considered as an alternative to a given PAC, the solution
must provide a comparable function to the PAC for the end user and bereadily available in the market.
Business as Usual (BAU) –The most commercially viable alternative product/application/PAC to a given product or PAC being evaluated.
Life cycle impact on climate – A PAC’s GHG emissions per functional unit
through the life cycle is evaluated against a reference scenario18 using an
Alternative.
Contribution –Each PAC is evaluated for its contribution to the Targets andIndicators associated with the 17 UN SDGs. Contribution is measured in
two dimensions: 1) Significance, indicating the relative role of the Chemours’ product in the complete PAC helping to meet the SDG, and 2) Magnitude, the relative importance of the PAC for achieving the SDG.
Corporate Responsibility Commitment (CRC) –Chemours’ public commitment to bring responsible chemistry to life, and hold ourselves accountablefor our progress.
Environmental Fate –How a substance distributes (e.g., to air, water, soil)
and changes in the environment.
Exposure –Both the amount of and the frequency with which a chemical
substance reaches a person, group of people, or the environment.
Fluorinated Organic Chemicals Emissions –These are emissions of fluorinated organic chemicals to air and water from our manufacturing processes. Fluorinated organic chemicals are defined as compounds containing
one or more carbon-fluorine bonds. Air emissions of these compounds aretracked for GHG reporting purposes, and both air and water emissions willbe tracked for our Water goal.7

EVOLVE 2030: Sustainable Offerings Assessment Method27

Functional Unit –ISO 14040 International Standard for Life Cycle Assessment (LCA) defines functional unit as, “…a measure of the performanceof the functional outputs of the product system. The primary purpose of
a functional unit is to provide a reference to which the inputs and outputs
are related. This reference is necessary to ensure the comparability of LCA
results. Comparability of LCA results is particularly critical when different
systems are being assessed to ensure that such comparisons are made on
a common basis. EXAMPLE: The functional unit for a paint system may be
defined as the unit surface protected for a specified time period.”
Greenhouse Gas (GHG) –The six gases listed in the Kyoto Protocol: carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); hydrofluorocarbons(HFCs); perfluorocarbons (PFCs); and sulphur hexafluoride (SF6).19

Globally Harmonized System (GHS) –Globally Harmonized System of Classification and Labeling of Chemicals.20
Global Warming Potential (GWP) –A factor describing the radiative forcing
impact (degree of harm to the atmosphere) of one unit of a given GHG relative to one unit of CO2.21
Hazard –Hazard refers to the inherent properties that make a substanceable to cause a risk, e.g., make it capable of causing harm to human healthor the environment. Risk is the measure of potential harm based on both
hazard and exposure. Exposure describes both the amount of and the frequency with which a chemical substance reaches a person, group of people,
or the environment. When chemicals are discussed in the context of a “riskassessment,” it refers to a comprehensive evaluation of both the inherent
hazard of a particular substance as well as the exposure.
Imprint –Aligned with the WBCSD PSA, the “Imprint” is a method to create
an understanding of the PAC’s net impact on society and the environment.
The Imprint includes several attributes with direct links to Chemours CRC
goals, (e.g., impact on climate change, landfill intensity, and emissions offluorinated organic compounds to air and water) as well as additional attributes covering topics such as risk to human health and public sentiment.

and Reporting Standard

Imprint Attribute –The Imprint includes 10 attributes which each assess a
specific environmental or social impact of the PAC.

EVOLVE 2030: Sustainable Offerings Assessment Method28Intensity –Expression of impact per unit of physical activity or unit of economic value (e.g., tonnes of CO2 emissions per unit of electricity generated).22
Magnitude –The relative importance of the solution for achieving the SDG.
Offerings –Refers to a specific Chemours product, service, or group of
products or services.
Portfolio Management –Approach that provides characterization andstratification across all products within a company’s portfolio, allowing forreporting of performance (e.g., per revenue) as well as prioritization of action (e.g., putting focus on innovating new products that can replace poorly
performing current products)
Portfolio Sustainability Assessments (PSA) –For the purposes of
EVOLVE 2030, PSA refers to the WBSCSD PSA Methodology, a holistic
approach designed to: 1. Build a common understanding of what is considered “sustainable” within product portfolios; 2. Improve robustness ofexisting PSA approaches, by adopting best practice approaches applied bypeers; 3. Increase credibility of externally communicated results, by agreeing on requirements with which a high-quality PSA must comply; 4. Reducecomplexity for companies starting with PSA, by providing pragmatic “howto” guidelines and case examples; 5. Improve consistency in communication
on sustainability attributes and performance.6
Product Application Combination (PAC) –A PAC is a set of products andapplications for which environmental and social impact (both positive andnegative) is similar as per the WBSCD Chemical Industry Methodology
for Portfolio Sustainability Assessment (the WBCSD PSA or simply “PSA
method”). It is a segmentation approach intended to allow for the evaluationof unique impacts that result from the product (offering) in specific applications across the full life Cycle. For efficiency, products and applications aregrouped as much as possible—i.e., products with similar operational footprints and benefits to society, if possible, are grouped into the same PACs.
Product Sustainability Risk Assessment Executive Review –The ProductSustainability Risk Assessment (PSRA) is a standard process designed toassist Chemours’ employees and businesses to responsibly manage theenvironmental, health, safety, sustainability (EHSS) and regulatory aspects
and impacts of Chemours raw materials, products and services throughout
22

 dapted from Intensity RatioA

the life cycle and across the value chain in order to minimize risks and maximize business value. A PSRA Executive Review is when participants review
EVOLVE 2030: Sustainable Offerings Assessment Method

29and accept ongoing management of action items designed to minimize risks
and maximize business value.
Refresh –An update to the evaluation of a PAC (Imprint and/or Contribution)
conducted either as part of a regularly scheduled update or triggered bya change occurring relative to one or more evaluation criteria, e.g., a newalternative to the PAC becomes viable in the market, a change in the manufacturing process is expected to alter the Imprint score.
Relative to Alternative –For some scoring, comparison to an alternativetechnology is central to the evaluation. For example, “Life cycle impact on
climate,” defined as CO2e emissions avoided less that caused by the PAC

under evaluation, necessarily compares the impact of using the subject PAC
with its alternative.
Revenue –For purposes of the EVOLVE 2030 method, revenue refers to
the total sales value (USD) of a given PAC for the fiscal year being assessed.
Risk Ratio –The ratio of a health benchmark versus the estimated concentration in an environment. The risk ratio will vary according to the populationin the environment; sometimes the population is the general public (in thecase of consumer goods), other times the population is workers on a manufacturing line.
Significance –Relative role of the Chemours’ product/offering in the PAC
helping to meet the SDG.
Solution –The WBCSD PSA defines solution as, “…Any product in its application along the value chain, a chemical product, a material from anotherindustry, a component or a final technology which fulfills the need of thepurchaser.”
Specific Contribution –PACs that are considered to have a specific contribution are those whose score places them in Quadrant A of the EVOLVE
2030 Matrix (Figure 4); therefore, the PAC has been demonstrated to havean Imprint score greater or equal to zero and a Contribution score of 6 orgreater.
Substances of the PAC –These include intentional components and identified impurities and degradants.

EVOLVE 2030: Sustainable Offerings Assessment Method30

Sustainable Offering –A part of Chemours’ broader Corporate Responsibility Commitment goals, the Sustainable Offerings goal is to ensure 50% ormore of our revenue will be from offerings that make a specific contribution
to the United Nations Sustainable Development Goals by 2030.
Toxicity –Ability of a substance or article to cause health-related damage toan organism (both mammalian and aquatic) or the environment.
United Nations Sustainable Development Goals (UN SDGs / SDGs) – The
2030 Agenda for Sustainable Development, adopted by all United Nations
Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are
the 17 Sustainable Development Goals (SDGs), which are an urgent call for
action by all countries—developed and developing—in a global partnership.
They recognize that ending poverty and other deprivations must go hand-inhand with strategies that improve health and education, reduce inequality,
and spur economic growth – all while tackling climate change and working
to preserve our oceans and forests.5

7. Appendix I:
Revisions to
EVOLVE2030 V1.0

Revisions to EVOLVE 2030 resulted from (1) experiences of conducting
PAC evaluations over the last several years, (2) findings from a reproducibility study in 2021, (3) the development and pilot testing of material circularity assessment method from 2021 to 2023, and (4) third-party assurance conducted in 2023-2024. In addition, our PAC evaluation process
has evolved with the development of data management and visualization
systems that have brought greater efficiency, discipline, robustness, clarity,
and accessibility to nearly every stage of our process.
The results of the reproducibility study led to the development of a detailed
operations manual, along with scores of tools, including decision trees,
templates, and process flow diagrams.
Because the environmental risk of site operations is reviewed in a separate
process, it became apparent during our work since 2019 that a separate
assessment of Environmental Risk during manufacture was redundant.
Therefore, the two parts of that attribute were consolidated into a single
score based on the properties of the substances associated with the PACs.
This is now more consistent with the human health scoring, which has
always considered only the PACs from gate to grave rather than including ascore for manufacturing.
While relying heavily on WBCSD CTI in developing the method to evaluate
material circularity, other references from the Ellen MacArthur Foundation,
the United Nations Environment Programme, the U.S. Environmental Protection Agency, and the European Parliament were also incorporated into
our approach and implementation.
