II. General Information

A. What is the purpose of this request for public comment?

    The EPA will use the feedback and information received through this 
public comment process, along with findings of the external peer review 
and data quality assessment, to inform future improvements to WARM.
    The Environmental Protection Agency launched the Waste Reduction 
Model (WARM) in 1998. WARM has been updated and expanded fifteen times 
since its launch in 1998. In 2022 and 2023, WARM underwent an external 
peer review and a data quality assessment as part of the EPA's on-going 
efforts to ensure WARM's scientific integrity. (Reports are available 
in the docket EPA-HQ-OLEM-2023-0451 and on the web at https://epa.gov/warm.)
    The EPA created WARM to provide high-level comparisons of potential 
greenhouse gas (GHG) emissions reductions, energy savings, and economic 
impacts (labor hours, wages and taxes when considering different 
materials management practices. Materials management practices 
include--source reduction, recycling, anaerobic digestion, combustion, 
composting and landfilling.
    WARM models 61 materials commonly found in municipal solid waste 
(MSW) and construction and demolition debris (C&D), including aluminum 
cans, glass, paper, plastics, organics (including food waste) and 
building materials.
    WARM is a comparative tool rather than a comprehensive measurement 
tool. WARM was not developed for and, as such, should not be used for 
final site-specific materials management decisions, when other human 
health and environmental impacts of the different management methods 
may need to be considered (such as air pollution, water pollution, 
noise, etc.). It also should not be used for developing GhG 
inventories, which need to establish a baseline and measure reductions 
over time on an annual basis for an entity.

III. Request for Information

    The Environmental Protection Agency requests public comment on WARM 
v16 and its supporting documentation from a broad range of individuals 
and organizations with an understanding of and interest in tools and 
models related to life cycle materials management, such as: federal, 
state, tribal, territorial, and local governments; industry; 
researchers; academia; non-profit organizations; community groups; 
individuals and international organizations. EPA is interested in 
receiving input on the following:
    <bullet> How can the scientific rigor and adherence to modeling 
best practices and assumptions in WARM regarding biogenic carbon 
emissions, carbon storage in forests, soils, and landfills, and utility 
offsets from combustion be improved?
    <bullet> How can WARM better align with best practices in climate 
change modeling and assumptions?
    <bullet> How can the alignment of data, assumptions, and model 
components in WARM with real market practices be improved?
    <bullet> In assessing WARM, how well do the modeled management 
practices represent the diversity of practices typically used in the 
United States?
    <bullet> When evaluating WARM, how accurately does it depict the 
common secondary use of recycled materials in the United States?
    <bullet> What recommendations can be made for enhancing the 
clarity, transparency, relevance, and usability of WARM and its 
accompanying documentation?
    <bullet> Are there any studies or data sources that are relevant to 
WARM but are currently not integrated, and how could their inclusion be 
beneficial for future development?
    <bullet> What are the potential advantages and disadvantages of 
conducting future WARM model development in a more publicly accessible 
development environment, such as GitHub, to encourage increased 
transparency and public involvement?
    <bullet> What are the potential advantages and disadvantages of the 
EPA considering the use of readily available data from public sources 
(such as the Federal LCA Commons) in WARM, especially the use of non-
waste management data, to enhance data consistency, accessibility and 
reliability across federal government life cycle work?
    The Environmental Protection Agency will use feedback and 
information received through this public comment, the external peer 
review and the data quality assessment to inform future improvements to 
WARM. Please identify the question(s) you are responding to when 
submitting your comments.

IV. Disclaimer and Important Note

    This request for public comment is issued solely for information, 
research and planning purposes and does not constitute a Request for 
Proposals (RFP) or a Request for Applications (RFA). Responding to this 
notice will not give any advantage to or preclude any organization or 
individual in any subsequently issued solicitation, RFP, or RFA. Any 
future development activities related to this activity will be 
announced separately. This notice does not represent any award 
commitment on the part of the U.S. Government, nor does it obligate the
