The Union of Concerned Scientists argues that increasing Minnesota's renewable energy standard to 40 percent by 2030 would drive over $6 billion in new capital investments and reduce reliance on imported electricity without significantly impacting retail rates. The analysis indicates that such a policy would increase wind capacity to nearly 6,000 MW and utility-scale solar to over 600 MW by 2030. While a strengthened RES helps position the state to comply with the EPA's Clean Power Plan, the report notes that coal would still provide 38 percent of electricity in 2030 without additional policy actions. The authors recommend combining the strengthened RES with an increased energy efficiency standard of 2 percent annually by 2020.

The report finds that while Democrats are more likely than Republicans to believe in human-caused global warming and support climate action, liberal and moderate Republicans often align with the mainstream public. Conservative Republicans remain the primary group opposed to climate action and skeptical of global warming. There is broad cross-party support for renewable energy research and tax rebates for energy-efficient products, though significant divisions persist regarding carbon taxes and emission limits on coal plants.

The report asserts that the combined fortunes of the world's wealthiest individuals could fund a total transition to renewable energy in the Global South by 2030. It estimates that $5.15 trillion is required to meet the energy demands of Africa, Latin America, and non-OECD Asia (excluding India and China). The authors argue that the energy transition must go beyond substituting fuel sources to include democratic ownership of resources and the dismantling of corporate power to address the intersecting crises of climate change and extreme inequality.

The handbook defines Sustainable Public Procurement (SPP) as a process to optimize value-for-money across an asset's lifecycle, rather than focusing solely on the lowest purchase price. It provides a framework for integrating sustainability into every stage of the procurement cycle—from needs analysis and market consultations to technical specifications and contract conditions. The document details specific mandatory and optional criteria for high-spend categories such as IT equipment, vehicles, and infrastructure, while emphasizing the use of the Most Economically Advantageous Tender (MEAT) principle. It also outlines strategies to support small and medium-sized enterprises (SMEs) and the potential for SPP to act as a catalyst for inclusive green growth and foreign direct investment.

The report examines the critical pressures facing South African agriculture, including resource scarcity, climate change, and socio-economic inequality. It highlights the interdependence of food, water, and energy systems, warning that current trends in soil degradation, water over-abstraction, and biodiversity loss threaten long-term productivity. The document calls for a shift toward sustainable farming practices, improved land-use planning, and coordinated governance to protect the natural resource base while feeding a growing population.

The briefing examines the rapid rise of Podemos in Spain, analyzing its positions on corruption, inequality, democracy, and European policy, while highlighting its influence on traditional left-wing parties and the strategic challenge it poses to ecological parties in Southern Europe.

The document marks the 30th anniversary of the 1984 Union Carbide disaster in Bhopal, India, which released toxic gases from a pesticide factory, affecting over 500,000 people and causing more than 25,000 deaths. It criticizes Dow Chemicals, which acquired Union Carbide, for continuing to avoid accountability while promoting 'green' initiatives like 'green plastic' and 'climate smart agriculture'. The statement advocates for a legally binding UN system to judge corporations for ecocide and human rights violations.

The author defends the EPA's use of the Clean Air Act to mandate deep carbon pollution reductions in the power industry, rejecting claims by certain members of Congress that federal subsidies for clean coal projects prohibit those technologies from being used to set performance standards. The author asserts that the EPA relies on a global array of projects to demonstrate that carbon capture and sequestration is a viable 'best system of emissions control'.

The World Resources Institute (WRI) welcomes the 2014 climate pledges from the U.S. and China, noting that the U.S. target of cutting emissions 26-28% below 2005 levels by 2025 and China's goal to peak emissions around 2030 provide critical momentum for the Paris agreement. While praising the cooperation, WRI emphasizes that China's emissions should peak before 2030 to mitigate severe climate impacts and urges both nations to exceed their initial targets to leverage low-carbon economic opportunities.

The report estimates that a transition to a low-carbon economy could put nearly $25 trillion of fossil fuel asset value at risk, with approximately 80% of this risk borne by governments rather than private investors. The analysis highlights that oil represents the majority of value at risk (close to 75%), while coal offers the highest emissions reduction potential with relatively low stranding risk (12%). The document argues that the net economic impact depends heavily on policy: a purely tax-based approach to reducing oil demand could cost the global economy $3 trillion, whereas an innovation-led transition could yield a net benefit of $7 trillion. It recommends prioritizing the phase-out of coal and utilizing financial mechanisms to lower the cost of renewable energy in emerging markets.

The report warns that tidal flooding will become chronic and disruptive for many US coastal communities by 2030 and 2045, necessitating urgent local adaptation and national carbon emission reductions.

The report analyzes 52 tide gauges from Maine to Texas, projecting that by 2045, many U.S. East and Gulf Coast communities will face a ten-fold increase in tidal flooding. It argues that such flooding will disrupt daily life, damage infrastructure, and necessitate a coordinated national response combining local adaptation—such as elevating roads and restoring wetlands—with global carbon emission reductions.

The Union of Concerned Scientists (UCS) proposes a 'Demonstrated Growth Approach' to replace the EPA's conservative renewable energy targets in the Clean Power Plan. The UCS argues that the EPA underestimates the cost-effectiveness and deployment rates of wind and solar power. By adopting the UCS methodology, the EPA could increase the 2030 share of renewable energy in U.S. electric sales from 12 percent to 23 percent, potentially increasing total power sector emissions reductions from 30 percent to approximately 40 percent below 2005 levels. The brief asserts that these higher targets are affordable, with minimal impact on consumer electricity prices and a potential 9 percent reduction in the national average price of natural gas for the electricity sector by 2030.

The briefing proposes that China can avoid energy insecurity and pollution by 'reinventing fire'—transitioning from fossil fuels to energy efficiency and renewables. It identifies three key areas for transformation: oil-free mobility, integrative design for buildings and industry, and redefining the electric grid. The text focuses on oil-free mobility, suggesting that combining vehicle lightweighting (using carbon-fiber composites) with electrification can reduce energy needs by half to two-thirds and make electric vehicles more economic. It also emphasizes the need for logistics optimization to address low loading rates and the use of advanced biofuels or hydrogen for heavy-duty transport where electrification is not viable.

The research paper investigates the effectiveness of Bonus-Malus schemes for promoting energy-efficient household appliances in Spain, specifically focusing on dishwashers, refrigerators, and washing machines. The authors develop a methodology to optimize the combination of taxes and subsidies to minimize dead weight loss (DWL) while meeting specific policy goals such as emission reductions or budget neutrality. The study finds that while simple subsidies can lead to welfare loss and increased energy bills due to a higher total number of appliances, a combined tax-subsidy approach can more effectively shift the market toward efficient goods. For instance, achieving a 10% emission reduction for dishwashers would be most effective by taxing both labelled and non-labelled goods, though this results in a significant reduction in the total number of appliances. Conversely, budget-neutral schemes can increase the share of efficient appliances but may inadvertently increase total energy consumption if the increase in efficient units outweighs the reduction in inefficient ones.

The document details the EPA's trajectory in regulating greenhouse gases (GHGs) following the 2007 Supreme Court ruling in Massachusetts v. EPA. It outlines key milestones including the 2009 Endangerment Finding, the development of fuel economy standards for light- and heavy-duty vehicles, and the introduction of the Clean Power Plan to reduce carbon pollution from power plants. The timeline also tracks critical judicial decisions that have both affirmed and limited the EPA's authority under the Clean Air Act.

The report examines the 'peace potential' of oil and gas resources, analyzing how joint development, revenue sharing, and infrastructure projects like pipelines can either mitigate or fuel conflict. It contrasts successful cooperation, such as the Saudi-Kuwaiti Partitioned Neutral Zone and Turkey-Iraqi Kurdish relations, with failures in the Caucasus and disputes in the South China Sea and Eastern Mediterranean. The study also addresses the role of international environmental law and the climate impact of transitioning from coal to natural gas.

California's climate strategies, centered on the Global Warming Solutions Act of 2006, are reducing oil use and emissions from the transportation sector, which accounts for nearly 40% of the state's global warming emissions. Key mechanisms include a cap-and-trade program, the Low Carbon Fuel Standard (LCFS), and stringent vehicle emissions standards. These policies have led to a 12% drop in oil consumption between 2006 and 2012 and are projected to save drivers money through increased fuel efficiency. Additionally, the state is investing carbon permit proceeds into disadvantaged communities and seeing a boom in clean technology investment and patent registrations.

The Rocky Mountain forests are facing a "triple assault" of tree-killing insects, wildfires, and heat and drought, all driven by human-caused global warming. Bark beetle outbreaks killed trees on 46 million acres between 2000 and 2012, while large wildfires increased by 73 percent from 1984 to 2011. Iconic species like whitebark pines, aspens, and piñon pines are in catastrophic decline, with projections suggesting a 60 percent loss in suitable area for aspens by 2060 under medium-high emissions scenarios. The report argues that without reducing heat-trapping emissions and managing for resilience, these forests may be irrevocably degraded.

The authors defend their use of a simple, transparent global oil model to estimate that the Keystone XL pipeline could increase global emissions by 0 to 110 million tonnes CO2e annually. They argue that the U.S. State Department's Environmental Impact Statement ignores the dynamic relationships between oil production, prices, and demand. While acknowledging uncertainties in supply elasticity and market behavior, they maintain that their approach allows for a range of possible supply responses and encourages open debate over 'black box' models.
