The Union of Concerned Scientists proposes a "Clean Path Case" for Pennsylvania to meet its Clean Power Plan target of reducing emissions by 29 million tons (24% below 2012 levels) by 2030. This pathway combines a mass-based carbon emissions trading program with strengthened renewable energy and energy efficiency policies. The analysis indicates that this approach would yield over 10,700 MW of new wind and solar capacity, generate $804 million in average annual revenue from carbon allowance auctions, and provide $4.5 billion in cumulative health and economic benefits through 2030. Long-term, the plan is projected to reduce typical residential electricity bills by 3.4% by 2030 compared to a reference case with no new policies.

The document highlights a growing problem where U.S. transportation fuels are becoming 'dirtier' as oil companies shift toward unconventional sources like tar sands and use high-emission extraction methods such as fracking. It argues that while vehicle efficiency has improved by 20 percent, these gains are undermined by the increasing emissions associated with extracting and refining oil, which can vary from less than 50 to 250 kilograms of CO2e per barrel. To counter this, the report advocates for eliminating wasteful practices like flaring, requiring better emissions disclosure, and shifting toward advanced biofuels made from wastes and perennial grasses. It also emphasizes the role of electric vehicles, noting that their climate benefit depends on the grid; for example, charging an EV in California produces only 35 percent of the emissions of a conventional vehicle.

The Union of Concerned Scientists proposes a "Clean Path" for Virginia to comply with the Clean Power Plan by transitioning from voluntary to mandatory renewable energy and energy efficiency targets and implementing a mass-based carbon emissions-trading program. The analysis suggests this approach would reduce CO2 emissions by 77 million tons through 2030 compared to a reference case, lower typical residential electricity bills by 5% by 2030, and generate an average of $241 million in annual auction revenue for state investments. The report highlights Virginia's current underutilization of its renewable potential, noting that non-hydro renewables accounted for only 2.8% of electricity generation in 2014.

The report analyzes the Eastern Interconnection Planning Collaborative (EIPC) study to demonstrate that aggressive carbon reductions in the U.S. electric sector are achievable with minimal additional cost. By re-evaluating EIPC data, Synapse Energy Economics found that a 'Carbon Reduction' scenario—featuring massive wind build-out and coal retirements—costs approximately the same as a 'Business as Usual' scenario when carbon revenues are recycled. The analysis shows that this path would allow the MISO and PJM regions to significantly over-comply with the Clean Power Plan's emissions targets while maintaining grid reliability.

Earthjustice calls on the Obama administration to end the Forest Service's attempt to reopen a loophole allowing coal mining in 20,000 acres of Colorado roadless forest. The document asserts that mining 170 million tons of coal would release 130 million tons of carbon from combustion, displace 40,000 gigawatt hours of renewable power, and undermine Colorado's 2014 oil and gas rules. It highlights that the state's solar and wind industries employ over 10,000 people, significantly more than the approximately 300 jobs associated with the specific mine in question.

The document outlines a strategy for Virginia to exceed its Clean Power Plan goals through a revenue-raising carbon trading program and mandatory energy standards. It highlights the state's significant renewable energy potential and projects substantial economic and health benefits, including billions in capital investments and pollution avoidance by 2030.

The report analyzes 384 sources in English, Chinese, and Spanish to assess the sustainability impacts of Chinese outward direct investment. It identifies a tension between the positive contributions to infrastructure and economic growth and the negative impacts related to labor conditions, environmental degradation, and governance. The review highlights a 'learning curve' where Chinese firms and policymakers are increasingly adopting corporate social responsibility (CSR) and international standards, though a gap remains between policy and project-level implementation.

The report finds a deep partisan divide in climate perceptions, with supporters of Democratic candidates (Sanders and Clinton) and some Republican candidates (Kasich and Trump) generally believing global warming is happening, while Ted Cruz supporters are the most skeptical. While a broad majority of voters support renewable energy research and tax rebates for energy efficiency, support for carbon taxes and strict emission limits on coal plants drops significantly among Republican supporters, particularly those of Ted Cruz. Global warming is viewed as a very important voting issue primarily by Sanders and Clinton supporters, whereas it ranks low for supporters of Republican candidates.

The report finds that while 73% of registered US voters believe global warming is happening, there is a significant divide between conservative Republicans and other political groups. Most voters support clean energy research and carbon regulation, and are more likely to vote for a presidential candidate who supports climate action than one who opposes it.

The report reveals a deep partisan divide in climate change perceptions. Supporters of Democratic candidates (Sanders, Clinton) and some Republican candidates (Kasich, Trump) generally believe global warming is happening, whereas a majority of Ted Cruz supporters do not. While there is broad support across most candidate groups for renewable energy research and tax rebates for energy-efficient products, significant gaps exist regarding carbon taxes, CO2 regulation, and the importance of climate change as a voting issue.

The report finds that while a majority of US registered voters believe global warming is happening and support various clean energy policies, significant ideological divides persist. Democrats and liberal/moderate Republicans generally align with the mainstream public in supporting climate action, whereas conservative Republicans remain the most skeptical group, though they have shown the largest increase in belief that global warming is occurring over a two-year period. Public awareness of the scientific consensus on human-caused warming remains very low across all political groups.

The author asserts that the Paris agreement's success is rooted in the collapsing cost gap between clean and fossil energy and the increasing profitability of low-carbon investments. The text highlights that private sector investment is driving climate finance, which grew 18% to $391 billion in the previous year. Specific examples are provided of economic opportunities in the U.S., Europe, India, China, Indonesia, and Brazil, suggesting that the transition to low-carbon energy and sustainable agriculture can unlock trillions in economic value.

The document reports that decarbonization in the power and transport sectors is exceeding previous predictions. It highlights a faster-than-expected shift away from coal in the EU, US, and China, as well as wind and solar capacity growth that has surpassed forecasts. In transport, passenger vehicle fleets in key economies are less carbon-intense than in 2005, and the market penetration of electric drive vehicles is exceeding predictions.

The We Mean Business Coalition advocates for a 2020 deadline for the first review of global carbon reduction targets, asserting that waiting until 2025 would create excessive uncertainty for business planning and investment. The document highlights the rapid pace of technological change in solar PV, wind power, and electric vehicles as a primary reason for more frequent reviews. It further argues that a 2020 ratchet would signal ambition to investors, helping to leverage $100bn in public climate finance into trillions for climate-smart infrastructure. The text notes that over a hundred global companies have already adopted 'science-based targets' and over fifty influential companies have committed to 100% renewable energy by mid-century or sooner.

The paper examines two contrasting models for financing clean infrastructure in middle-income countries: Brazil's centralized approach led by the national development bank (BNDES) and India's decentralized system involving various public and private institutions. Through case studies of wind energy projects, the authors find that despite their structural differences, both systems are dominated by public financing and struggle with a lack of true non-recourse project finance and limited financial innovation. Brazil's model effectively supports national industrial goals through local content requirements and centralized auctions but faces risks of crowding out private investment and governance issues. India's model allows for more diverse participants and smoother integration of international development finance but suffers from higher system costs, uneven investment across sectors, and significant revenue risks due to the poor financial health of state-owned power distribution companies (discoms). The report concludes that the effectiveness of these models is heavily dependent on complementary regulatory and policy frameworks rather than the financing structure alone.

This collection of papers analyzes regional integration efforts in three key areas: South America, Southern Africa, and Russia. It argues that while traditional trade-led integration has often stalled, new drivers such as regional value chains (RVCs), energy pooling, and strategic investment shifts offer paths toward deeper cooperation. In South America, the report finds a lack of a clear 'hub country' and significant infrastructure gaps hindering RVCs. In Southern Africa, it highlights the potential of the Southern Africa Power Pool (SAPP) and the dual role of South Africa as both a catalyst and a diverter of regional investment. In Russia, the analysis focuses on a strategic 'turn to the East,' shifting investment focus from Europe toward the Asia-Pacific region and the Eurasian Economic Union (EEU).

The briefing challenges the notion that variable renewables will limit their own growth by depressing wholesale electricity prices. It contends that these concerns rely on static models of the grid and ignore the synergistic effects of complementary supply resources, flexible demand-side responses, and the decreasing cost of storage. By shifting from incremental to whole-system thinking and updating 20th-century market designs, the author asserts that wind and solar can continue to expand without facing practical economic limits.

The guide suggests that while direct arguments about global warming are often counterproductive, common ground can be found by discussing shared environmental values, concerns about air pollution and biodiversity, and support for renewable energy and energy-efficiency behaviors.

The document argues that the Arecibo Waste-to-Energy and Resource Recovery Project is unnecessary, economically unviable, and environmentally hazardous. It claims the Draft Environmental Impact Statement (DEIS) fails to meet National Environmental Policy Act (NEPA) standards by ignoring reasonable alternatives, underestimating public health risks—particularly lead exposure in a non-attainment area—and omitting cumulative impacts on human health and biological resources. The authors contend that the project violates the Rural Electrification Act's mandate to serve rural areas and would cause irreversible damage to the Caño Tiburones Natural Reserve.

The document provides a comprehensive overview of 'green jobs' in the US and internationally, highlighting the growth of sectors like solar, wind, and energy efficiency. It notes that the US Bureau of Labor Statistics ceased its Green Careers program in 2013, leading to a reliance on fragmented data from multiple sources. Globally, the International Renewable Energy Agency (IRENA) identifies China as the leader in renewable energy employment, with solar PV being the largest global employer in the sector.
