Climate Central's analysis of 244 U.S. cities reveals that 93% have seen an increase in cooling degree days and 87% have experienced more warm nights since 1970. The report highlights the role of urban heat islands and the increasing reliance on air conditioning, which costs Americans over $27 billion annually for home cooling as of 2015. While energy efficiency standards may reduce cooling electricity consumption by nearly 20% by 2040, the report warns that fossil-fuel-powered cooling and improper appliance disposal exacerbate climate change.

The report argues that global fossil fuel subsidies, estimated at USD 425 billion in 2015, represent a massive untapped financial resource that could fund universal energy access multiple times over. It contends that untargeted consumption subsidies are often regressive, benefiting wealthier households and potentially hindering energy access by straining utility budgets and encouraging fuel smuggling. The authors propose a 'Remove, Target, and Swap' framework: removing subsidies with no energy access benefit, targeting necessary subsidies toward the poor (e.g., through connection subsidies), and swapping fossil fuel support for investments in renewable energy and energy efficiency.

The document advocates for the European Union to lead the 'Mission 2020' initiative, which aims to bend the global emissions curve by 2020 to stay within the 2-degree Celsius limit of the Paris Agreement. It argues that the EU can use its existing institutional frameworks, specifically regional cohesion and structural funds, to support a just transition toward low-carbon economies. The text emphasizes a shift from centralized energy production to decentralized, community-based renewable energy systems to empower local actors and counteract populist movements. It cites historical industrial transitions in regions like the Ruhr Area as evidence that such structural changes can be managed. Additionally, it highlights the role of bottom-up movements, such as the Transition Town Movement and the fossil fuel divestment movement, in driving decarbonization.

The study identifies that high financing costs in Tunisia, driven by power market, counterparty, and political risks, inflate the cost of renewable energy. By implementing targeted public derisking measures, Tunisia could significantly lower generation costs for wind and solar PV, catalyzing over EUR 1.6 billion in private investment and reducing carbon emissions by 32.2 million tonnes of CO2 over 20 years. The analysis concludes that the economic savings from lower capital costs outweigh the public expenditure required for these instruments.

RMI and Uber collaborated on an EV Pilot in Austin, Texas, to transition high-mileage rideshare drivers to electric vehicles. Through driver focus groups and education sessions, the project identified key barriers to adoption—including insufficient DC fast charging, range anxiety, and lack of awareness regarding cost savings—and developed strategies to address them, such as in-app notifications for riders and strategic charging infrastructure deployment by Austin Energy.

The document examines the global landscape of high-speed rail (HSR), highlighting the leadership of China, Japan, and Europe in deployment. It contrasts this with the United States, where HSR is largely absent due to factors like low population density, car culture, and property rights. The text argues that HSR offers significant energy and environmental advantages over air and car travel, while noting that China's rapid expansion is driven by government funding and strategic goals for economic integration and energy independence.

Carbon Market Watch warns that the development of new supersonic business jets by aviation entrepreneurs and NASA requires new environmental certification for noise and CO2 emissions. The letter argues that these aircraft must meet existing and future subsonic standards to prevent environmental deterioration and uphold the Paris Agreement.

India faces twin challenges as it scales renewable energy: the need for increased grid flexibility and the risk of coal-based plants becoming economically unviable due to falling plant load factors (PLFs). The report argues that transitioning existing coal plants into flexible resources is a cost-effective short-term solution. This conversion requires technical retrofits to allow for lower minimum loads, reduced start-up times, and increased ramp rates. While this path involves incremental costs of 5-10% of total project costs in NPV terms, it is significantly cheaper than deploying lithium-ion batteries or pumped hydro. The report recommends market-based mechanisms, such as capacity auctions and revised power purchase agreements, to compensate plant owners and ensure a transition toward a low-carbon electricity system.

The Canadian Association of Physicians for the Environment and partner organizations support the 2030 coal phase-out but warn that the proposed Gas Regulations may encourage investment in inefficient natural gas technologies. They highlight significant health risks from hydraulic fracturing and the high climate-forcing potential of methane. The submission recommends lowering CO2 emission limits for new and medium-sized units, banning inefficient coal-to-gas boilers after 2029, and requiring offsets for emissions during emergency maintenance.

The report argues that the UK can transition directly to clean power generation by 2025, bypassing the need for a 'gas bridge' of new large gas plants. It finds that renewables, particularly offshore wind, along with interconnectors and battery storage, are sufficient to replace coal capacity. The document suggests that relying on large gas plants would be costly and lock in higher emissions, recommending instead a focus on long-term storage innovation and policies to limit emissions from small peaking gas generators.

The guide explains that the carbon-reduction impact of renewable energy projects varies by location because different projects displace different types of power plants. It argues that relying on proximity to operations as a proxy for quality may limit environmental benefits, suggesting instead that buyers target the most carbon-intensive areas to maximize avoided emissions.

The paper examines the Spanish light-duty vehicle market to determine how consumer behaviour—specifically whether they make 'absolute' or 'relative' decisions—influences the effectiveness of energy efficiency labels and financial incentives. Using the Quantity Based Demand System (QBDS), the authors calculate price elasticities of demand to show that the sensitivity of consumers to price changes varies depending on whether they seek the most efficient car in the entire market or the most efficient car within a specific segment. The study concludes that a mixed labelling scheme may be the most effective way to address diverse consumer behaviours.

The report highlights the economic and environmental advantages of transitioning transportation network company (TNC) drivers to electric vehicles. It demonstrates that high-mileage drivers can achieve significant annual savings in fuel and maintenance, which eventually offset the higher initial purchase price of EVs. Using Austin, Texas, as a case study, the document details specific utility incentives and compares EV acquisition methods—purchasing, renting, and leasing—to guide TNC drivers toward electrification.

The Institute for Policy Integrity submits that the New York Public Service Commission correctly applied the Social Cost of Carbon to internalize the external costs of carbon emissions when pricing zero-emissions credits for nuclear generators. This mechanism supports the state's Clean Energy Standard goal of reaching 50% renewable generation by 2030 by preventing potential pollution increases that would occur if nuclear plants closed.

The study finds that while woodfuel demand contributes to moderate degradation in Haiti, it is less severe than typically portrayed, though a business-as-usual scenario predicts a 4%±1% decline in above-ground woody biomass by 2027.

The document details the STF's decision that the 2012 Forest Code does not result in environmental regression, while specifying five points of unconstitutionality. It explains the benefits available to producers who deforested before July 22, 2008, including the suspension of fines through Environmental Regularization Programs (PRAs) and flexible restoration requirements. The briefing emphasizes that registration in the Rural Environmental Registry (CAR) by May 31, 2018, is mandatory for accessing these benefits and obtaining rural credit. It concludes that the law's implementation is essential for Brazil to meet its Paris Agreement goals, specifically the restoration of 12 million hectares and the elimination of illegal deforestation.

A March 2018 survey of 1,067 registered US voters reveals broad bipartisan support for renewable energy and carbon pollution limits, despite significant political divides over the causes of global warming and the priority level assigned to climate action. While 73% of voters believe global warming is happening, only 40% of conservative Republicans share this view. However, majorities across the political spectrum support funding renewable energy research and regulating carbon dioxide. The report also notes a gap between stated support for climate action and actual individual engagement, with only 13% of voters having contacted an elected official about global warming in the previous year.

The report outlines a multi-pronged approach to building cooling, emphasizing the transition from active air conditioning to passive design and high-efficiency technology. It details various technical solutions—ranging from 'super-efficient' AC units and passive cooling techniques to wearable devices and the use of waste cold from LNG terminals. The document also analyzes policy levers such as Minimum Energy Performance Standards (MEPS) and behavior change campaigns like Japan's 'Cool Biz'. Finally, it explores innovative business models to improve affordability for the poor, including Pay-As-You-Go (PAYG), ESCO models, and public-private partnerships in countries like India, Mexico, and Bangladesh.

The report examines the growing global need for cooling, driven by urbanization and rising incomes, particularly in developing countries. It warns that a surge in air conditioning (AC) use could lead to massive increases in electricity demand and urban heat island effects. The document also details the critical role of cold chains in reducing food loss and ensuring vaccine viability, while emphasizing the need to 'leapfrog' high-emission cooling technologies to avoid severe environmental impacts.

The document examines the impact of stopping new fossil fuel leases on U.S. federal lands and waters, estimating a reduction of 280 million tons of annual global CO2 emissions by 2030.
