The document discusses the launch and objectives of the Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants (CCAC), based on UNEP and WMO assessments. It highlights 16 existing technological measures to reduce methane and black carbon that could lower global warming by 0.5C by 2050 and prevent millions of premature deaths. The text emphasizes that SLCP reduction is a development issue that complements long-term CO2 targets and focuses on practical implementation through national action planning and international collaboration.

The report proposes a U.S. cap-and-trade system to limit global warming emissions, citing the success of the 1990 Acid Rain Program. It outlines design criteria including a stringent declining cap, full auctioning of allowances, and the inclusion of all major heat-trapping gases. The author emphasizes that while cap-and-trade is a lynchpin, it must be paired with parallel sector-based policies to be effective.

The document examines how climate change, specifically increasing temperatures, creates a 'climate penalty' that elevates ground-level ozone levels despite efforts to reduce precursor emissions. Using the BenMAP model, it estimates the health incidences and economic costs associated with ozone increases of 1 ppb, 2 ppb, and 7 ppb for the years 2020 and 2050 across various U.S. states.

The document advocates for immediate action to combat climate change using existing technologies. It identifies fossil fuel combustion and deforestation as the primary drivers of CO2 increase and proposes five 'common sense' solutions: increasing vehicle fuel efficiency, modernizing the electricity system with renewables, improving energy efficiency in buildings, protecting forests, and increasing federal R&D for clean energy. It emphasizes that these steps would reduce emissions while saving consumers money and enhancing energy security.

The document argues that integrating the mitigation of short-lived climate pollutants (SLCPs)—including methane, black carbon, hydrofluorocarbons, and tropospheric ozone—into economic recovery plans allows governments to simultaneously achieve immediate economic stability and long-term climate and public health goals. It focuses on the energy, agriculture, transport, and waste sectors as primary sources of these emissions and targets public policymakers to encourage the use of both immediate stimulus and long-term transformational policies to drive this recovery.

The document defines GHG emissions registries as databases for tracking emissions from individual emitters, distinguishing them from top-down national inventories. It details the legal mandate for the U.S. Environmental Protection Agency to develop a national registry by mid-2008, funded by a December 2007 appropriations bill. The text outlines the role of registries in cap-and-trade programs—specifically for ensuring compliance and market efficiency—and describes the technical requirements for data collection, quantification, and verification to ensure consistency and transparency.

The United States proposed greenhouse gas reduction targets of 17% by 2020 and 26-28% by 2025 relative to 2005 levels. WRI analysis suggests these targets are achievable through the aggressive implementation of federal and state policies, including President Obama's Climate Action Plan. However, further significant action is required to align the U.S. trajectory with a 2°C long-term goal.

The report identifies three primary sources of agricultural methane: enteric fermentation (55-60%), rice cultivation (18-20%), and manure management (6-8%). It highlights scalable solutions such as methane-inhibiting feed additives, solid-liquid manure separation, and modified rice irrigation practices, noting that while many are cost-effective, adoption is hindered by economic and technological barriers.

The document examines the use of waste-derived Renewable Natural Gas (RNG) in the United States as a means for businesses, states, and municipalities to utilize waste-derived methane and lower the carbon footprint of vehicle fleets. It specifically explores the conditions necessary for RNG to achieve significant greenhouse gas (GHG) emissions reductions relative to fossil fuels.

The document argues that reducing short-lived climate pollutants (SLCPs)—specifically methane, hydrofluorocarbons, black carbon, and tropospheric ozone—is critical for staying within a 1.5°C temperature rise and avoiding climatic tipping points. It notes that these pollutants were frequently underrepresented in initial NDCs and suggests that strengthening future NDCs with SLCP-specific actions is essential for achieving the Paris Agreement and Sustainable Development Goals.

The World Resources Institute and partners have developed a standardized geospatial dataset to operationalize the GHG Protocol’s Land Sector and Removals Guidance for corporate reporting. The dataset provides emission factors for 42 major crops across global, national, provincial, and municipal levels for the years 2020–24, covering carbon dioxide, methane, and nitrous oxide. Findings indicate significant variation in emissions by crop and region, with subnational data revealing 'hotspots' that national averages obscure.

The document provides recommendations for the 2007 Farm Bill to better integrate greenhouse gas mitigation into U.S. agricultural policy, specifically calling for the inclusion of nitrous oxide and methane reductions and the assessment of environmental tradeoffs in conservation programs.

The U.S. GHG Emissions Flow Chart provides a detailed breakdown of 2003 emissions totaling 6,978 MtCO2 equivalent. The largest contributing sectors are Electricity & Heat (32.4%) and Transportation (27.2%), with Carbon Dioxide (CO2) accounting for 85% of the total gas composition.

The document presents a flow chart of global greenhouse gas emissions for 2000, totaling 41,755 MtCO2 equivalent. It identifies Electricity & Heat (24.6%) and Land Use Change (18.2%) as the largest contributing sectors, while Carbon Dioxide (77%) is the dominant gas species.

The American Power Act (APA) proposes a comprehensive US framework to reduce greenhouse gas emissions through a mandatory cap-and-trade system, targeted emission reduction goals, and strategic investments in clean energy. The bill establishes a phased-in cap on covered gases, starting in 2013 and reaching an 83 percent reduction below 2005 levels by 2050. It includes specific provisions to expedite nuclear power development, deploy carbon capture and sequestration (CCS), and provide financial assistance to consumers and workers during the transition to a low-carbon economy. The APA also addresses international climate activities, including the use of international offsets and border adjustments to prevent carbon leakage.

The document outlines how the loss of Arctic sea ice—which is declining at nearly 13% per decade—triggers global impacts including more intense heatwaves, sea level rise, food system instability, and the release of methane from thawing permafrost.

The report argues that large-scale US dairies can reach net zero emissions within five years by integrating specific technologies and practices, potentially increasing annual net returns to $1.9 million per dairy. Key strategies include precision agriculture, feed additives to reduce enteric methane, and anaerobic digesters that convert manure and organic substrates into renewable energy and fertilizers. The analysis emphasizes that while technologies exist, achieving these goals requires significant policy shifts, such as expanded water quality trading markets and improved EPA processing of renewable fuel pathways.

The WWF's Food Waste Warrior curriculum uses student-led audits and wildlife-focused education to reduce food waste in U.S. schools. Piloted in Washington, D.C., the program emphasizes a hierarchy of prevention, donation, and diversion. Key findings include the effectiveness of student-led audits in reducing plate waste, the impact of on-site scratch cooking versus pre-packaged meals, and the barriers to food donation and composting in school settings.

The document outlines 60 practical steps for individuals to mitigate their impact on the planet.
