The Government of Canada's proposal for a Clean Fuel Standard (CFS) received strong stakeholder support, with broad agreement on the necessity of contributions from all economic sectors to meet national emission reduction targets.

The United States produces over 70 million tons of organic waste annually, yet utilizes less than 20 percent of its biogas potential. By employing anaerobic digestion to process livestock manure, food waste, and crop residues, the U.S. could add 13,500 new biogas systems, creating over 350,000 total jobs and significantly reducing methane emissions. Biogas can be used for on-site heat and power or refined into renewable natural gas (RNG) for pipelines and vehicles, with the potential to replace 10 percent of U.S. natural gas. Key policy drivers include the Renewable Fuel Standard (RFS) and various USDA and DOE funding programs, though some face appropriation reductions.

The United States produces over 70 million tons of organic waste annually, yet only 2,200 biogas systems are currently operating, representing less than 20 percent of the total potential. Biogas, produced via anaerobic digestion, can be used for heat, electricity, or upgraded to renewable natural gas (RNG) for pipelines and vehicles. The document highlights that expanding to 13,500 additional systems could create over 335,000 construction jobs and 23,000 permanent jobs while significantly reducing methane emissions. Key feedstocks include food waste, landfill gas, livestock manure, wastewater sludge, and crop residues. Federal support is provided through the Renewable Fuel Standard (RFS), the Farm Bill, and agency programs like AgSTAR and the Landfill Methane Outreach Program.

The document summarizes over 125 written submissions and workshop contributions regarding the proposed Canadian Clean Fuel Standard (CFS). Stakeholders generally support the CFS's goal of reducing GHG emissions by 30 Mt annually by 2030, though they diverge on the feasibility of the timeline and the specific regulatory design. Key areas of discussion include the preference for an emission intensity-based approach over volumetric mandates, the need for flexible compliance pathways such as credit trading, and the importance of harmonizing the CFS with existing carbon pricing and international aviation and marine standards. Industrial sectors expressed significant concerns regarding competitiveness, carbon leakage, and the technical feasibility of fuel switching, while environmental groups advocated for broad sustainability criteria and the inclusion of indirect land use changes (iLUC) in life-cycle analyses.

The document summarizes stakeholder responses to Canada's proposed Clean Fuel Standard (CFS). While there is broad support for the goal of reducing greenhouse gas emissions by 30 Mt by 2030, stakeholders express divergent views on regulatory design, specifically regarding sector-specific targets, the inclusion of indirect land-use change (ILUC) in life-cycle assessments, and the potential for policy duplication with carbon pricing. Key concerns include the economic impact on trade-exposed industries, the feasibility of infrastructure for low-carbon fuels, and the need for harmonization with international standards in aviation and shipping.

The document examines how California's LCFS and Cap-and-Trade Program work together to reduce transportation emissions. The LCFS mandates a reduction in the carbon intensity of fuels, while Cap-and-Trade puts a price on carbon and generates revenue for clean technology investments. The author argues that neither policy is sufficient alone and recommends extending both to 2030 to provide the stability needed for long-term infrastructure and vehicle transitions.

The document examines biomethane derived from landfills, wastewater treatment centers, and dairies as a replacement for diesel and natural gas in California's heavy-duty vehicle fleets. While acknowledging its climate benefits over fossil fuels, the authors highlight that California's total biomethane potential from waste would meet only 3% of the state's natural gas demand and 15% of its diesel consumption. The report warns that promoting compressed natural gas (CNG) vehicles could inadvertently increase reliance on fossil natural gas due to this supply gap. It concludes that biomethane provides the greatest emissions reductions when used to generate electricity or hydrogen for electric vehicles, but that battery electric vehicles powered by the grid remain the most effective path for meeting climate goals.

The document analyzes the evolution of ethanol use in the U.S., noting that while E10 blends have reduced oil dependence, corn-based ethanol causes significant environmental damage and can spike global food prices. It argues for a shift toward advanced biofuels derived from wastes, agricultural residues, and perennial crops to lower lifecycle emissions and protect biodiversity. The report forecasts that by 2050, emissions from biorefineries, agriculture, and land use can be substantially reduced through technological optimization and smarter crop choices.

The report analyzes pathways for California, Oregon, and Washington to reduce transportation petroleum use by 50% by 2030. It identifies a 'Half the Oil' (HtO) Pathway that distributes reductions across travel demand management, vehicle efficiency, and alternative fuel deployment. While existing policies are projected to reduce consumption by 24% in California and 8% in Oregon and Washington by 2030, achieving the 50% target requires extending and accelerating these measures. The analysis finds that relying on a single category of strategy is insufficient to meet the target, and that Washington faces greater challenges due to a lack of enforceable alternative fuel and zero-emission vehicle policies.

The document outlines a pathway for California to halve its oil use by 2030 by extending and enhancing existing policies on vehicle efficiency, electrification, and land use planning.

The document provides a technical appendix describing the life cycle emissions modeling for urban buses in California, comparing diesel, compressed natural gas (CNG), hydrogen fuel cell, and battery electric options. It details modifications to the CA-GREET 2.0 and Vision 2.0 models to better reflect California-specific fuel pathways and electricity grid mixes. Key findings include the significant reduction of global warming emissions when using 100% renewable energy for electric buses and the role of biomass and coal in the grid's particulate matter emissions. The analysis also examines the impact of low-carbon biofuels and low-NOx engines on overall emissions profiles.

The document outlines the economic and environmental benefits of transitioning Oregon's transportation sector from petroleum to clean fuels, specifically electricity and biofuels. It highlights the cost-effectiveness of electric vehicles (EVs) and the state's potential to produce advanced biofuels from waste, residues, and energy crops. Central to this transition is the Clean Fuels Program, which aims for a 10 percent reduction in carbon emissions per unit of fuel by 2025 and aligns with regional policies in California and British Columbia to create a larger market for low-carbon alternatives.

The United States generates over 250 million tons of municipal solid waste and 9 trillion gallons of wastewater annually, yet recovers less than 18 percent of the potential 10.5 million metric tons of biomethane available. Current landfill systems are inefficient, leading to significant fugitive methane emissions, while many wastewater treatment facilities lack anaerobic digesters or flare excess biogas. The document advocates for a shift toward organic waste diversion and anaerobic digestion, which can result in negative lifecycle emissions. It highlights the potential for waste-derived fuel to power 10.4 million cars or 13.7 million homes and suggests that the EPA's designation of biogas-derived electricity as a renewable biofuel could generate 90 million renewable identification numbers (RINs) annually to support electric vehicle infrastructure.

The Union of Concerned Scientists (UCS) identifies a significant opportunity for the United States to utilize agricultural residues and manure to reduce oil and coal dependence. By 2030, the U.S. could tap 155 million tons of residues and nearly 60 million tons of manure, which could generate over 10 billion gallons of ethanol or 166 billion kilowatt-hours of electricity. The document emphasizes that sustainable use requires balancing energy needs with soil health, suggesting that no-till farming and cover crops can mitigate erosion. Geographically, a small number of states, led by Iowa, hold the majority of this potential, with specific opportunities identified in Arkansas, Texas, and California based on their dominant crops and livestock.

The roadmap proposes two visions for Colombia's bioenergy sector: one focusing on new technologies (biomethane and biomass-based power/CHP) and another combining these with the expansion of first-generation biofuels. Modeling indicates that while both scenarios increase the bioenergy share in power and gas supply, they cannot prevent an overall decline in bioenergy's share of primary energy demand due to rapid GDP growth and urbanization. The most effective emissions reductions come from power generation and CHP, particularly by avoiding methane release from landfills and animal waste. Scenario I is identified as the most efficient in terms of emissions reduction per additional hectare of land, whereas Scenario II's ambitious biofuel targets would require significant imports as domestic land is insufficient.

The report investigates the feasibility of producing biomethane from organic waste and energy crops in Harju County, Estonia. It compares two primary scenarios for the Hinnu pig farm: using biogas for combined heat and power (CHP) or upgrading it to biomethane for transport fuel. The analysis concludes that while CHP may offer higher immediate business profitability due to feed-in tariffs, upgrading to biomethane provides greater overall social and environmental benefits, particularly when considering the EU Emissions Trading System.

The report investigates the feasibility of producing biomethane from waste in Lääne-Viru County, Estonia. It identifies a total biomethane production potential of up to 24.4 million m3/a by 2020, with energy crops as the largest resource. The study proposes a pilot plant in Rakvere using wet digestion technology and amine scrubbing for purification. While combined heat and power (CHP) is more profitable for a private operator due to feed-in tariffs, the report concludes that using biomethane as motor fuel provides higher social and environmental benefits for society as a whole.

The document argues that capturing biogas—primarily methane—from organic waste sources is a cost-effective method to mitigate climate change and displace fossil fuels. It details the technical and economic viability of landfill gas (LFG) projects, wastewater treatment anaerobic digestion, and agricultural manure digesters, while identifying policy barriers such as high capital costs and grid interconnection issues.

A group of doctors and nurses issued a health advisory to the British Columbia government, warning that the expansion of liquefied natural gas (LNG) and hydraulic fracturing (fracking) poses severe risks to public health. They highlight the acceleration of climate change via methane leaks, air pollution causing respiratory and cardiovascular diseases, water depletion and contamination, and adverse community impacts including mental health issues and human rights violations against Indigenous peoples. The advisory calls for a moratorium on new fracking, stricter pollution regulations, an end to natural gas tie-ins in buildings by 2023, and support for workers and Indigenous communities transitioning to a clean-energy economy.

The Canadian Association of Physicians for the Environment (CAPE) and other applicants argue that the Canadian Gas Association (CGA) has engaged in greenwashing by marketing natural gas as a clean and affordable energy source. The document asserts that natural gas has a lifecycle climate impact comparable to coal, causes significant indoor and outdoor pollution, and is less affordable than heat pumps, especially as carbon pricing increases. The applicants request a Competition Bureau inquiry, a public retraction of the claims, and a $10 million fine.
