The report finds that building electrification is generally cost-effective for new construction and for customers switching from propane or heating oil, but often more expensive for existing natural gas customers at current prices. It argues that electrification reduces carbon emissions in most US regions, except those heavily dependent on coal, though this is expected to change as coal plants retire. The authors emphasize that demand flexibility—shifting energy use to low-cost or high-renewable periods—can further improve economics and grid integration. Key recommendations include prioritizing the electrification of oil and propane homes, stopping the expansion of natural gas infrastructure, and updating energy efficiency standards to account for total energy reduction across fuels.

The document examines the production and use of renewable natural gas (RNG) as a climate strategy in the United States, focusing on its potential to reduce greenhouse gas (GHG) emissions when derived from organic waste. It identifies that RNG is most effective when produced from waste rather than dedicated land and when it results in net methane emissions reductions. The paper highlights promising feedstocks such as food and yard waste diverted from landfills and livestock manure. While RNG production costs are higher than conventional natural gas, the report notes that economic viability is supported by low-carbon fuel standards and federal incentives. However, it warns that RNG can increase net methane emissions if it comprises 'new methane'—methane that would not have otherwise entered the atmosphere—due to supply chain leakage. The authors call for more data on methane leakage and life-cycle carbon intensities to better integrate RNG into long-term climate plans.

The document evaluates the proposed Northwest Innovation Works methanol facility at the Port of Kalama, arguing that its greenhouse gas emissions are significantly underestimated and that it is unlikely to reduce global emissions. It proposes a 'climate test' for new industry to ensure projects do not lock in high-carbon technologies or become stranded assets in a transition to a low-carbon economy.

The author calls for a large turnout at the 2017 Peoples Climate March in Washington, D.C., to signal that Americans still care about climate change despite the political climate of the Trump administration. The text highlights the 2014 march as a catalyst for previous U.S. climate actions, such as the Clean Power Plan and the Paris agreement, and emphasizes the need for solidarity and systemic political accountability to protect the planet.

The report finds that 238 US counties in 21 states face cancer risks exceeding the EPA's 1-in-a-million threshold due to oil and gas emissions, affecting over 9 million people. Key pollutants identified include benzene, formaldehyde, and ethylbenzene, with the highest risks concentrated in states with significant infrastructure like Texas, Louisiana, Oklahoma, North Dakota, Pennsylvania, and Colorado. The analysis highlights that NATA likely underestimates total health impacts by excluding particulate matter, ozone, and water contamination. To mitigate these risks, the report recommends implementing leak detection and repair (LDAR) programs, replacing high-emitting pneumatic equipment, and installing vapor recovery units on storage tanks.

The document addresses four perceived barriers to the clean energy transition: the 'duck curve' ramping problem, the necessity of curtailing excess generation, the high cost of renewables, and the role of natural gas in emissions reductions. It argues that demand response and battery storage can manage variability, regional electricity trading can prevent waste, and energy efficiency combined with falling technology costs keeps customer bills low. Finally, it asserts that renewable energy and energy efficiency have contributed more to U.S. carbon emission declines since 2007 than the shift to natural gas.

The document celebrates the signing of the Paris Agreement and calls on the business community to move from government intent to implementation by adopting science-based targets, internal carbon pricing, and risk mitigation strategies to support the goal of keeping warming well below 2°C.

The report posits that Iran's nuclear power program is economically unviable and creates security ambiguities that could be resolved by shifting toward energy efficiency and renewables. It suggests that international cooperation in these sectors would align with Iran's economic interests, reduce the domestic case for nuclear power, and potentially halt a regional nuclear arms race. The author highlights Iran's significant wind and solar potential and compares this transition to experiences in Argentina and Brazil.

The study finds that approximately 75% of Joint Implementation (JI) offsets likely did not represent additional emission reductions, potentially increasing global GHG emissions by 600 million tonnes of CO2 equivalent. The analysis highlights systemic failures in additionality testing, the prevalence of retroactive crediting, and the lack of international oversight in Track 1 projects, particularly in countries with significant Assigned Amount Unit (AAU) surpluses like Russia and Ukraine.

The document analyzes Mexico's 2015 INDC, which commits to unconditional reductions of greenhouse gas (GHG) emissions by 22% and black carbon by 51% relative to a 2030 baseline. While noting Mexico's leadership as the first developing country to submit an INDC and its identification of a 2026 emissions peak, the analysis warns that current policy trajectories projected by external sources suggest emissions would continue to increase without further action. The authors recommend formalizing a robust baseline policy to avoid high-carbon lock-in and improving transparency regarding the expected emissions trajectory and the specific conditions required to meet conditional targets.

The Clean Air Task Force reports that over 60 organizations have urged the EPA to implement comprehensive methane standards for new and modified oil and gas equipment. The requests include mandatory leak detection and repair across the entire sector, extending green completions to oil wells with significant gas production, reducing emissions from liquids unloading and pneumatic equipment, and covering the full supply chain including transmission and storage.

The report examines the transition of the U.S. power sector from coal to natural gas, noting that while this shift provides immediate benefits, it introduces risks such as price volatility, methane leakage, and potential 'stranded assets'. Using the National Energy Modeling System, the analysis compares a 'Business as Usual' scenario with a 'Carbon Standard plus Renewables and Efficiency Policies' scenario. The findings suggest that the latter would reduce power plant carbon emissions by 70 percent below 2005 levels by 2040, lower consumer energy bills, and provide significant net societal benefits, reaching nearly $170 billion by 2040.

The 2015 update to the Massachusetts Clean Energy and Climate Plan for 2020 (CECP Update) outlines a comprehensive strategy to reduce greenhouse gas (GHG) emissions by at least 25% below 1990 levels by 2020. The plan identifies key drivers for these reductions, most notably vehicle GHG emission standards and the import of clean electricity. It also provides a framework for long-term goals, aiming for an 80% reduction by 2050 through a strategy of reducing energy consumption, decarbonizing the electricity supply, and electrifying transportation and heating. The report includes detailed assessments of building efficiency, transportation, electricity generation, and non-energy emissions, as well as research on land use and carbon storage in terrestrial and wetland ecosystems.

The document outlines how the U.S. economy can benefit from reducing greenhouse gas emissions in electric generation, electricity consumption, passenger vehicles, natural gas, and hydrofluorocarbons (HFCs). It highlights cost savings for consumers and businesses, the decreasing cost of renewable energy and electric vehicle batteries, and the potential for increased industry revenues through methane leak reduction.

The author argues that Dr. Charles R. Frank, Jr.'s analysis incorrectly concludes that nuclear and gas combined-cycle plants are more beneficial than wind and solar. By replacing Frank's data with empirical figures from the EIA and DOE, the author asserts that the priority for carbon savings actually shifts to hydro, wind, gas combined-cycle, nuclear, and solar. The critique highlights significant underestimations of renewable productivity and overestimations of gas and nuclear costs and reliability.

The document examines the risks of relying on natural gas for US electricity, noting that while it burns cleaner than coal, its expected replacement of nuclear power and its role in meeting rising electricity demand would prevent necessary emission cuts. It highlights that methane leaks from production and transport further erode climate benefits, and suggests that a transition to 80% renewable energy by 2050 is a viable, more cost-effective alternative.

Earthjustice supports President Obama's commitment to tackling carbon pollution from power plants and clean car standards, but argues that the U.S. must prioritize 'best of the above' clean energy over an 'all-of-the-above' strategy that includes natural gas and other fossil fuels.

The U.S. electricity sector is shifting from coal to natural gas, with natural gas projected to account for nearly two-thirds of electricity by 2050 if current trends continue. However, this transition risks generating up to three times the carbon emissions recommended by the National Research Council (NRC) to limit climate change. While natural gas provides near-term public health benefits and supports grid reliability for variable renewables, it remains a fossil fuel that emits carbon dioxide and leaks methane. To meet the NRC's carbon budget, the U.S. must increase the share of renewable energy in the power supply to 25 percent by 2025 and 80 percent by 2050.

The report argues that replacing coal with natural gas is insufficient to meet U.S. climate goals due to continued CO2 emissions and methane leakage. It highlights risks including water contamination from fracking, price volatility, and the potential to crowd out renewables. The authors advocate for a transition to a system where renewables and efficiency provide 80% of electricity by 2050.

Ohio is transitioning from coal to natural gas for electricity generation, but this shift maintains significant risks. The report advocates for a more diverse energy mix, highlighting the success of the Alternative Energy Portfolio Standard in reducing costs and creating jobs through wind, solar, and energy efficiency.
