The Institute for Local Self-Reliance (ILSR) is a national nonprofit research and educational organization that advocates for thriving, diverse, and equitable communities. We respectfully request your consideration of our comments and recommendations outlined in this letter, which have been informed by nearly 50 years of experience providing assistance to communities to reduce and recycle wasted materials.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">ILSR commends the EPA for its continuous efforts to improve and update the measurement tool and for seeking input through public comments. However, WARM 16 continues to have several flaws that hinder progress in mitigating and adapting to climate change. The current form falls short of its goal to allow for an adequate comparison among available solid waste management options. In response, ILSR offers the following recommendations to rectify several shortcomings in the tool that bias results and impede future efforts. <\/span>\r\n<ol>\r\n \t<li><span style=\"font-weight: 400;\">Include decentralized composting systems in emissions factors\u00a0<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Consider increased soil water retention in composting emissions factors<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Update research on compost\u2019s ability to displace synthetic fertilizers, fungicides, and pesticides\u00a0<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Factor bCO<\/span><span style=\"font-weight: 400;\">2\u00a0 <\/span><span style=\"font-weight: 400;\">emissions (carbon dioxide emissions from biogenic materials) into emissions calculations<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Update methane\u2019s Global Warming Potential (GWP) to 80.8 \u2013 82.5 over 20 years and an atmospheric life of 11.8 years to reflect IPCC\u2019s 2021 Assessment Report (AR 6)<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Reconsider utility CO<\/span><span style=\"font-weight: 400;\">2\u00a0 <\/span><span style=\"font-weight: 400;\">emissions in combustion net emissions calculations<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Report methane emissions separately from other GHGs<\/span><\/li>\r\n<\/ol>\r\n<span style=\"font-weight: 400;\">Furthermore, we urge EPA to strongly consider the copious additional benefits of composting not represented through emissions calculations when comparing solid waste management options. Excluding benefits such as improved climate resiliency and living natural systems creates an unfair disadvantage for closed-loop, nature-based solutions like composting. We thank you for your consideration of our recommendations. <\/span>\r\n\r\n&nbsp;\r\n\r\n<em><b>Recommendations for Waste Reduction Model (WARM)<\/b><\/em>\r\n<h4><b>1) Include decentralized composting systems in emissions factors<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">WARM 16 models composting only in central composting facilities with windrow piles, citing a lack of data for small-scale composting and other large-scale operations as the reason.\u00a0<\/span><span style=\"font-weight: 400;\">However, decentralized, distributed composting is a <\/span><strong><a href=\"https:\/\/ilsr.org\/composting-2022-census\/\" target=\"_blank\" rel=\"noopener\">quickly growing<\/a><\/strong><span style=\"font-weight: 400;\"> part of <\/span><strong><a href=\"https:\/\/nrcne.org\/wp-content\/uploads\/2019\/12\/BioCycle_StateOfOrganicsUS.pdf\" target=\"_blank\" rel=\"noopener\">the sector<\/a><\/strong><span style=\"font-weight: 400;\">, warranting its inclusion in WARM to represent the field accurately. 90% of composting programs in <\/span><strong><a href=\"https:\/\/ilsr.org\/composting-2022-census\/\" target=\"_blank\" rel=\"noopener\">our 2022 census<\/a><\/strong><span style=\"font-weight: 400;\"> launched since 2010, with over half launching since 2016. Of <\/span><strong><a href=\"https:\/\/nrcne.org\/wp-content\/uploads\/2019\/12\/BioCycle_StateOfOrganicsUS.pdf\" target=\"_blank\" rel=\"noopener\">2,987 composting facilities with scale data<\/a><\/strong><span style=\"font-weight: 400;\">\u00a0in a 2017 study, 79% were small-scale composters (composting less than 5,000 tons of feedstock per year). With this increase in decentralized activity, access to data should not be a barrier.<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Decentralized solutions, such as composting at home, community gardens, urban and local farms, schools, and local government sites, are managed by local, distributed networks of independent businesses, worker cooperatives, nonprofit organizations, and local governments. Community-based composting operations often make and use compost within the same community where wasted food and other materials are generated. Keeping the processes and products as local as possible keeps benefits and profits local and within the community. Decentralized composting offers abundant co-benefits that protect the climate, build healthy soils, stimulate economic growth, enhance food security, and build more prosperous, equitable, and resilient communities. Omitting decentralized composting operations from WARM 16 has created emissions factor modeling inaccuracies. <\/span>\r\n<ul>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">By excluding decentralized composting, emissions associated with transporting compost are inflated. Centralized composting operations are more likely than community composting operations to be located further away from the community where collection occurs, resulting in further distance traveled and higher transportation energy emissions. WARM 16 also assumes transport by a diesel short-haul truck. However, we are seeing a growth in clean energy modes of transportation in our network; a number of our community composting partners are <\/span><strong><a href=\"https:\/\/ilsr.org\/wp-content\/uploads\/2023\/03\/A-Growing-Movement-ILSR-2022-Census-of-Community-Composters.pdf?_gl=1*129srnp*_ga*ODMwOTI5NDUxLjE3MDA1OTI4NDQ.*_ga_M3134750WM*MTcwNzQyMjM5MS4yMjEuMS4xNzA3NDIyMzkxLjAuMC4w\" target=\"_blank\" rel=\"noopener\">using electric vehicles and bicycles<\/a><\/strong><span style=\"font-weight: 400;\"> (pedal and electric-powered) for collection. WARM should address the currently stated limitations that \u201cdid not allow for variation in transportation distances.\u201d\u00a0\u00a0\u00a0<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Leaving out decentralized operations renders emissions associated with turning equipment inaccurate. 44% of community composters <\/span><strong><a href=\"https:\/\/ilsr.org\/wp-content\/uploads\/2023\/03\/A-Growing-Movement-ILSR-2022-Census-of-Community-Composters.pdf?_gl=1*129srnp*_ga*ODMwOTI5NDUxLjE3MDA1OTI4NDQ.*_ga_M3134750WM*MTcwNzQyMjM5MS4yMjEuMS4xNzA3NDIyMzkxLjAuMC4w\" target=\"_blank\" rel=\"noopener\">did not use windrows for composting<\/a><\/strong><span style=\"font-weight: 400;\"> but used alternative methods with different levels of machinery (including manual labor only). Increasingly a number of community composters are powering aeration systems with solar and electric power and not fossil fuel energy. For example, LA Compost is moving toward electric-powered bobcats for their composting operations. Machinery emissions in the current model are likely inflated.<\/span><\/li>\r\n<\/ul>\r\n<span style=\"font-weight: 400;\">These discrepancies place decentralized composters at a disadvantage when utilizing WARM 16 for reporting and funding opportunities. The current version does not accurately reflect the impacts and benefits of their operations due to these inaccuracies. <\/span>\r\n<h4><b>2) Consider increased soil water retention in composting emissions factors<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">WARM 16 acknowledges that \u201ccompost use also has been shown to increase soil water retention; moister soil gives a number of ancillary benefits, including reduced irrigation costs and reduced energy used for pumping water.\u201d However, these benefits and avoided emissions are not included in WARM 16. Composting emissions factors should address these energy offsets to represent emissions benefits accurately. <\/span>\r\n<h4><b>3) Update research on compost\u2019s ability to displace synthetic fertilizers, fungicides, and pesticides<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">Synthetic <\/span><strong><a href=\"https:\/\/pulitzercenter.org\/stories\/nitrogen-fertilizer-releases-greenhouse-gases-throughout-its-life-cycle\" target=\"_blank\" rel=\"noopener\">fertilizers<\/a><\/strong><span style=\"font-weight: 400;\">, fungicides, and <\/span><strong><a href=\"https:\/\/grist.org\/agriculture\/a-new-report-says-pesticides-intensify-climate-change\/\" target=\"_blank\" rel=\"noopener\">pesticides<\/a><\/strong><span style=\"font-weight: 400;\"> collectively have an enormous greenhouse gas profile and should be accurately reflected in WARM. Outdated or inaccurate assumptions on composting\u2019s ability to displace fertilizer can understate the value of composting and compost application. Only looking at NPK nutrients is insufficient to calculate the offset of fertilizers as the benefits of compost have to do with soil structure and beneficial biology. Applying high-quality compost to agricultural soil as a soil health management practice can be crucial for both rebuilding and protecting soil. Compost as a soil amendment improves soil structure, increases soil fertility, suppresses plant disease, improves nutrient cycling, prevents soil erosion, and increases soil resilience to drought and extreme weather. We know farmers that have stopped using synthetic\/fossil fuel fertilizers altogether. Furthermore, not all compost is created equal. For example, vermicompost made from worms is higher in beneficial biology and growth hormones. EPA should take into consideration the use of vermicompost to adequately capture these advantages. This is an important issue that should be given continuous and adequate attention. The EPA should be looking to update WARM 16\u2019s data on this issue, which is now a decade old, and use multiple studies to inform assumptions. EPA should conduct ongoing research to continuously update this information to most accurately reflect the value of composting and compost application.<\/span>\r\n<h4><b>4) Factor bCO2 emissions (carbon dioxide emissions from biogenic materials) into emissions calculations<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">We support the excellent research of <\/span><strong><a href=\"https:\/\/www.energyjustice.net\/\" target=\"_blank\" rel=\"noopener\">Energy Justice Network<\/a><\/strong><span style=\"font-weight: 400;\"> and <\/span><strong><a href=\"https:\/\/www.no-burn.org\/\" target=\"_blank\" rel=\"noopener\">Global Alliance for Incinerator Alternatives (GAIA)<\/a><\/strong><span style=\"font-weight: 400;\"> on this topic.

WARM 16 assumes the carbon dioxide emissions from biogenic organic materials (e.g., paper and wood products, yard trimming, and food discards) do not count. The rationale is that plants and trees regrow, and carbon dioxide emissions return carbon to the atmosphere previously sequestered by photosynthesis and would cycle back eventually under natural conditions due to degradation processes. This assumption can exclude 90% of CO<\/span><span style=\"font-weight: 400;\">2 <\/span><span style=\"font-weight: 400;\">emissions from incineration but omits a smaller fraction of GHG emissions from landfill calculations (as the model counts methane but not CO<\/span><span style=\"font-weight: 400;\">2 <\/span><span style=\"font-weight: 400;\">emissions). Favoring disposal in an incinerator versus a landfill does not cause additional plant and tree regrowth. It is, therefore, biased to grant a large emissions discount to incinerators that does not equally apply to landfills. Although we promote the diversion of all organic materials from landfills or incinerators, WARM 16 <\/span><strong><a href=\"https:\/\/www.energyjustice.net\/files\/incineration\/DelcoLCA.pdf\" target=\"_blank\" rel=\"noopener\">incorrectly assumes<\/a><\/strong><span style=\"font-weight: 400;\"> incineration is better for the climate than landfilling.

Delaying the release of bCO<\/span><span style=\"font-weight: 400;\">2<\/span><span style=\"font-weight: 400;\"> for even short periods can help avoid overloading short-term atmospheric loading, which could trigger cascading tipping points in the Earth System.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Biogenic carbon in waste can also be stored for long periods. Wood can store significant fractions of biogenic carbon for up to 100 years; compost can trigger enhanced, long-term carbon sequestration in soil, etc. The IPCC acknowledges that 65% (range: 35-95%) of all biogenic carbon in landfills will remain in place for over a century.<\/span>\r\n<h4><b>5) Update methane\u2019s Global Warming Potential (GWP) to 80.8<span style=\"font-weight: 400;\"> \u2013<\/span>\u00a082.5 over 20 years and an atmospheric life of 11.8 years to reflect IPCC\u2019s 2021 Assessment Report (AR 6)<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">WARM 16 severely understates the global warming potential (GWP) of methane. <\/span><span style=\"font-weight: 400;\">WARM 16 uses the GWP factor from the Intergovernmental Panel on Climate Change (IPCC) 2007 Assessment. As such, WARM 16 calculates methane\u2019s GWP as 25, comparing methane to carbon dioxide on a 100-year basis. However, <\/span><strong><a href=\"https:\/\/www.ipcc.ch\/report\/ar6\/syr\/\" target=\"_blank\" rel=\"noopener\">IPCC\u2019s 2021 Assessment Report<\/a><\/strong><span style=\"font-weight: 400;\"> (AR 6) identifies methane as a short-lived greenhouse gas with a GWP of 80.8 \u2013 82.5 over 20 years and an atmospheric life of 11.8 years. Methane to carbon dioxide emissions conversions may be a shorthand inventory tool, but WARM is intended for decision-making purposes and should model real-world behavior. WARM 16 assumptions understate the benefits of avoiding methane through organic management practices and are inconsistent with approaches to reduce short-lived GHGs to slow the rate of climate change. <\/span><b>Indeed, all climate pollutants and greenhouse gas emissions\u00a0<\/b><b>should be adjusted to a 20-year climate horizon, not 100 years.<\/b>\r\n<h4><b>6) Reconsider utility CO2 emissions in combustion net emissions calculations\u00a0<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">We support <\/span><strong><a href=\"https:\/\/www.energyjustice.net\/\" target=\"_blank\" rel=\"noopener\">Energy Justice Network<\/a><\/strong><span style=\"font-weight: 400;\">\u2018s excellent research on this topic. WARM 16 assumes that electricity generated by combustion avoids using fossil fuels on the electric grid and, therefore, subtracts avoided fossil fuel emissions in net calculations. However, most incinerators are displacing renewable energy sources, not fossil fuels. At least two-thirds of U.S. trash incinerators that generate electricity operate in states where they are eligible to sell renewable energy credits (RECs) to electric utilities under state renewable energy mandates. Many of these incinerators are selling RECs in these markets, directly competing with actual renewable energy sources (mainly wind, solar, and hydroelectric). If utilities could not buy RECs from trash incinerators to meet state mandates, they would have to buy them from actual renewable energy sources. In these cases, trash incinerators are displacing renewable energy, not fossil fuels. Therefore, subtracting these emissions as avoided from combustion net calculations is inappropriate.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Additionally, the electric grid is rapidly shifting from coal to wind and solar. <\/span><strong><a href=\"https:\/\/ilsr.org\/community-solar-tracker\/\" target=\"_blank\" rel=\"noopener\">ILSR tracks this here<\/a><\/strong><span style=\"font-weight: 400;\">. WARM 16 assumptions regarding fossil fuel avoidance are exceedingly outdated for waste planning purposes. Even if modeling with the most recently available data, WARM 16 calculations do not reflect fossil fuel\u2019s share of the electricity grid looking forward. WARM must provide future projections (or a heavy disclaimer) if used to support long-term decisions and investments in waste disposal methods.<\/span>\r\n<h4><b>7) Report methane emissions separately from other GHGs<\/b><\/h4>\r\n<span style=\"font-weight: 400;\">We support <\/span><strong><a href=\"https:\/\/www.no-burn.org\/\" target=\"_blank\" rel=\"noopener\">Global Alliance for Incinerator Alternatives (GAIA)<\/a><\/strong><span style=\"font-weight: 400;\">\u2019s excellent research on this topic.
