The document asserts that the Paris Agreement's universal and flexible nature allows it to proceed without the United States. It characterizes the U.S. withdrawal as a historical, economic, and geopolitical error that ignores climate science and risks isolating the country. However, it notes that key actors like China, India, and the European Union remain committed, and that internal U.S. resistance from states like California, New York, and Washington, as well as support from major corporations, provides a counterweight to the federal decision.

The paper examines how subnational governments, with a focus on Washington State, can effectively use carbon tax revenues for greenhouse gas (GHG) mitigation. It argues against a narrow focus on the lowest-cost reductions, which often leads to pitfalls such as overpayment, lack of additionality, and long ramp-up periods. Instead, it recommends a strategic approach that targets market failures, promotes social equity, and leverages existing state programs to ensure rapid and effective deployment of funds.

The Union of Concerned Scientists (UCS) developed the Clean Energy Momentum State Ranking to evaluate how US states are driving the transition to clean energy. The ranking uses 12 metrics across three categories: technical progress (renewable energy generation, energy savings, and electric vehicle sales), direct effects (job creation and pollution reduction), and future-oriented policies (renewable energy, energy efficiency, and carbon reduction). California is identified as the overall leader, while Vermont, Massachusetts, Rhode Island, and Hawaii also rank in the top five. The analysis concludes that state-level leadership is critical for national momentum, particularly in creating jobs and improving public health, and recommends that states facilitate business involvement and improve energy equity for low-income communities.

The Union of Concerned Scientists (UCS) evaluated the 50 US states using 12 indicators to rank their progress in clean energy, focusing on renewable energy generation, energy efficiency, and transport electrification. California leads the ranking, followed by Vermont and Massachusetts. The analysis highlights that clean energy progress is tangible across the US, with wind farms in 41 states and over half a million electric vehicles on the road. The report argues that state-level leadership is critical for job creation and public health improvements, and recommends that states adopt multi-dimensional policies, facilitate corporate participation, and improve energy equity for low-income and minority communities.

The analysis finds that February 2017 was the second warmest February on record for the contiguous United States, with temperatures 3.1°C above the 1981–2010 normal. By combining historical observations with CMIP5, HadGEM3-A, and Weather@Home model ensembles, the study concludes that the probability of such a warm event has increased more than threefold due to human-induced greenhouse gas emissions. While the 2017 event had a return period of approximately 12 years in the current climate, it would have been a 1-in-160-year event around 1900. Projections suggest that by 2050, temperatures like those seen in February 2017 will be 'completely normal', occurring roughly every three years.

The document reports significant job growth in the U.S. clean energy sector as of early 2016. It highlights that solar and wind industries are expanding rapidly, with solar jobs growing 17 times faster than the overall economy and wind-turbine technicians projected as the fastest-growing occupation. Energy efficiency employs the largest volume of workers at 2.2 million. Geographically, Texas leads in wind jobs, while California leads in solar and energy efficiency jobs.

Earthjustice, representing St. Johns Riverkeeper and Miami Waterkeeper, urges the EPA to reject Florida's proposed water quality criteria revisions. The statement claims the Florida Department of Environmental Protection (FDEP) violated public participation laws and used an unsound probabilistic risk analysis that fails to protect sensitive populations, such as children and subsistence fishers. The document highlights drastic increases in allowable concentrations for several toxins and the failure to regulate 22 substances recommended by the EPA.

The legal marijuana industry in the US creates significant electricity demand due to high-intensity lighting and climate control, with Colorado's industry consuming 300 GWh in 2015. To mitigate the impact on carbon goals and grid stability, the document recommends that utilities support LED adoption through rebates and on-bill financing to overcome capital limitations. It further suggests using time-varying rates to shift lighting schedules to periods of low net load—such as midday in California for solar or nighttime in Colorado for wind—to avoid peak demand and reduce reliance on fossil fuel generation.

The U.S. carpet industry is characterized by high waste, with 89% of discarded carpets ending up in landfills and 6% being incinerated. Despite the existence of the Carpet America Recovery Effort (CARE), only 1% of carpet waste is recycled back into carpet in a closed loop. The report argues that major manufacturers, particularly Shaw and Mohawk, engage in greenwashing and actively lobby against Extended Producer Responsibility (EPR) legislation to maintain a wasteful linear model. In California, the AB 2398 law has failed to achieve meaningful recycling increases because it relies on consumer fees rather than producer funding, and is administered by CARE, which the report claims is under the influence of the industry's largest players.

The report argues that the rapid growth of electric vehicles (EVs) requires a shift in regulatory paradigms to ensure that new loads benefit rather than impair the electricity grid. It emphasizes the role of state utility regulators in designing smart charging policies, rate structures, and infrastructure ownership models. Through case studies of California and Washington, the document illustrates different approaches to EV deployment and integration, highlighting the need for adaptive regulation, such as scalable pilots and scenario-based distribution planning, to manage the unpredictable nature of EV adoption.

Climate Central's analysis of U.S. Forest Service records shows that the average annual number of large wildfires in the western U.S. more than tripled between the 1970s and 2010s, with the area burned increasing more than six-fold. The report attributes these trends to rising temperatures, decreased snowpack, and earlier snowmelt. Projections using the Keetch-Byram Drought Index (KBDI) suggest that high-risk fire days will increase substantially by 2050, particularly in Southwestern states. The report also highlights the growing risk to populations living in the wildland-urban interface (WUI) and the health impacts of wildfire smoke.

The report outlines various in-lake remediation strategies to combat eutrophication in Manitoba's prairie lakes, emphasizing that these treatments should complement efforts to control external nutrient sources. It details three biological methods (biomanipulation, floating treatment wetlands, and macrophyte removal), five physical/engineering methods (hypolimnetic withdrawal, dilution/flushing, hypolimnetic aeration, artificial circulation, and dredging), and three chemical methods (phosphorus inactivation, sediment oxidation, and algicides), providing their benefits, shortfalls, suitable lake conditions, and associated costs.

The briefing provides a historical analysis of nuclear waste siting in the United States, asserting that the Department of Energy (DOE) has consistently failed to secure long-term consent for high-level waste (HLW) and spent nuclear fuel (SNF) repositories. The author highlights a pattern of broken promises, litigation, and the failure of both the Nuclear Waste Policy Act (NWPA) and the 'volunteer' process managed by the Nuclear Waste Negotiator. Key examples include the legal battles over the Waste Isolation Pilot Plant (WIPP) and the non-consent of the Nevada state government regarding Yucca Mountain. The document concludes that the DOE's lack of reliability makes it unlikely that future consent agreements for consolidated storage or repositories will be trusted or successful.

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 report outlines a three-step approach for improving the performance of publicly-owned utilities (POUs). The first step involves 'no regrets' actions, such as engaging diverse stakeholders to define goals and using Integrated Resource Plans (IRPs) to balance reliability, cost, and environmental targets. The second step focuses on governance evolutions, specifically delineating the roles of boards and management and implementing board self-evaluations. The third step suggests more drastic measures for lagging performance, including revenue decoupling to support energy efficiency, performance-based employee compensation, and the use of third-party non-profit entities for specific utility functions.

The report finds that battery-electric vehicles (BEVs) produce significantly lower lifetime global warming emissions than comparable gasoline cars, despite higher emissions during the manufacturing process. On average, BEVs sold in the U.S. produce less than half the emissions of gasoline vehicles, with the extra manufacturing burden offset within 6 to 16 months of driving. The environmental benefit of EVs increases as the U.S. electricity grid shifts from coal to renewable energy sources.

The chemical industry is using federal TSCA reform and the TTIP trade agreement to prevent US states from enacting chemical safety laws that exceed federal standards, potentially turning federal regulations into a ceiling rather than a floor.

The report presents seven 'deception dossiers' containing approximately 85 internal documents that reveal how fossil fuel companies and trade associations intentionally spread climate misinformation. It details tactics such as the secret funding of contrarian scientists, the creation of 'astroturf' grassroots groups, and the use of forged letters to Congress to undermine climate science and delay the transition to clean energy.

Earthjustice and a coalition of local governments and environmental groups are appealing the 'Hazardous Materials: Enhanced Tank Car Standards and Operational Controls for High-Hazard Flammable Trains' final rule. They contend that the rule violates the Administrative Procedure Act by abandoning the notification requirements of the May 2014 Emergency Order without public comment. The appeal argues that the new system—which relies on rail routing analysis and voluntary industry practices—provides retrospective, aggregated data that is less useful to first responders than the weekly, county-level notifications previously required. Furthermore, the petitioners argue that the DOT is improperly restricting public access to train route information by treating it as sensitive security or confidential business information without a legal basis.

In Q1 2015, 44 green bonds totaling $7.2 billion were issued. The market showed signs of maturation through the use of 11 different currencies and credit ratings ranging from AAA to B-. India emerged as a key player with its first corporate green bonds from Yes Bank, while US municipal bonds grew in the water and green building sectors, though often lacking independent verification. Development banks remained leaders, accounting for approximately 46.2% of issuance. Renewable energy, green buildings, and water were the primary funding targets. Investors showed strong demand, evidenced by oversubscription and the formation of dedicated green bond funds and investor expectation statements to combat 'greenwashing'.
