Why measure and manage yourscope 3 emissions• Mandatory Disclosure - of Scope 3/Supply Chain emissions is becoming
more popular and requires reporting in their Annual Reports (SECR,
PPN 06/21).
• Voluntary Disclosure - The Carbon Disclosure Project and Science
Based Target Initiative are actively promoting the need for Scope 3carbon footprint reporting.
• Internal Understanding –-Identify and respond to carbon ‘hot spots’ in your supply chain.
-Save cost and improve sustainability in your supply chain.

Where to Begin
Scope 1 and 2, understand your own footprint first.
Scope 3 emissions are someone else's scope 1 and 2. Despite this, it should betracked and reported to give better supply chain understanding and to drive change.

Two Options
Option 1 – Gap Analysis
Options 2 – Screening (Cost or Average Based)© Carbon Footprint Ltd 2022

Data Availability
Primary- Exact usage data from operations (e.g. Fuels,AVAILABILITY

Mileage, Materials).

Secondary- Data from global average emissions factors
based on known processes.

Tertiary- Cost Based Analysis to identify key data sources toACCURAC
Y

help identify where to target the above data. Need the abovedata to have measurable reductions.

Where to begin –Spend based carbon assessment•••

Using cost-based factors to estimate supply chain GHG emissions based on financial spend.
Identify “Hot Spots”, typically the top 3 sources to focus on.
Report on findings, identifying suppliers contributing to your Organization's footprint.

Some downstream emissions sources may need modeling if not directly paid fore.g. Distribution, Product Use and Waste.

Progression

Improving data as you go

Hybrid approachYear 1 – 100% Tertiary
DataYear 2 – Primary orsecondary data for the
top 3 identified sources.

Year 3 – Working with
suppliers to reduceemissions. Majority
Primary or secondary.

Year 5 – A better
understanding of yoursupply chain allowing
more data and more
influence

Shifting toward primary andsecondary data allows for tracking
and measuring emission reductions© Carbon Footprint Ltd 2022

Recap••••

Reduce overall emissions through identifying hotspots.
Tenders to becoming part of or remaining in supply chains.
Go above and beyond minimum reporting to show Environmental understanding.
Show green credentials, differentiate your brand and show transparency.

The aim of this talk was to:• Identify your next step and a potential strategy for understanding yourScope 3 emissions• Identify the benefits of monitoring your scope 3 emissions/supply chain• Provide details on how extensive and how far a supply chain can stretch© Carbon Footprint Ltd 2022
