China's steel industry is dominated by emissions-intensive BF-BOF technology, which accounted for almost 94% of industry emissions in 2022. While the Ministry of Industry and Information Technology (MIIT) set a target of 15% EAF production by 2025, the document argues that China already possesses the capacity (151 mtpa) to meet this goal if utilization rates are increased. Achieving a more ambitious 20% EAF target by 2025 could reduce industry emissions by 217 mtpa CO2, nearly 11% of 2022 levels. Key obstacles to this transition include scrap steel distribution and power supply stability, though the growth of scrap availability and offshore wind energy provides opportunities for decarbonization.

The report examines how governments can monitor green public procurement (GPP) to track progress toward climate goals. It categorizes monitoring into institutionalization, outputs, and outcomes, while detailing specific tools for measuring CO2 impacts. Through case studies of South Korea, Japan, Slovenia, Denmark, Malaysia, and the Netherlands, it identifies key success factors such as strong legal mandates and e-procurement integration. It also highlights significant barriers, including data insufficiency, decentralized procurement structures, and a lack of specialized technical skills. The document concludes with recommendations for governments to define clear targets, mandate monitoring through policy, and strengthen data management systems.

The report evaluates the Bogota MRT system using the SAVi methodology, which integrates externalities like health, carbon emissions, and retail growth into a cost-benefit analysis. The analysis considers two demand scenarios (8% and 16% modal shift from private transport) over a 35-year period (2022–2058). While conventional benefit-cost ratios (BCR) are low (0.4 to 0.6), the sustainable BCR (S-BCR) ranges from 1.5 to 2.9, indicating the project is highly profitable from a societal perspective. Key benefits include significant retail revenue increases, health improvements from walking and reduced pollution, and a reduction in CO2 emissions by up to 10.79 million tonnes in the high-demand scenario.

The report applies the SAVi methodology to analyze two scenarios for Bogota's transport infrastructure: a current scenario (20102022) focusing on BRT and NMT, and a future scenario (20102058) including the MRT system. The analysis finds that while conventional benefit-cost ratios (BCR) are low (0.3 to 0.6), the sustainable BCR (S-BCR), which incorporates externalities like health, retail revenues, and CO2 emissions, is significantly higher (3.8 to 6.1). The most substantial added benefits are identified as retail revenues and property value increases, while the only negative value is the time lost due to increased walking and cycling. The report concludes that the strategy is an attractive investment that improves quality of life and supports climate targets.

Since 1970, spring temperatures in the contiguous U.S. have increased by an average of 2°F, with the most significant warming occurring in the Southwest. Analysis of 239 locations shows that 96% of cities experienced warming, with some locations in Nevada, Texas, and Arizona exceeding 6°F. This trend is characterized by an increase in warmer-than-normal spring days, which contributes to earlier snowmelt, prolonged allergy seasons, and extended agricultural growing seasons.

The SAVi assessment of the Tirana–Durres railway in Albania indicates the project is highly profitable, with a benefit-cost ratio of 4.79 and cumulative discounted net benefits of EUR 415.51 million between 2023 and 2053. The primary economic drivers are avoided vehicle operating costs resulting from a shift from road to rail, followed by health benefits from reduced air pollution and increased physical activity, as well as time savings.

The policy brief advocates for 'clean repowering'—the strategy of siting new renewable energy projects at existing or retiring fossil fuel plant interconnection points—to reduce interconnection times from nearly five years to less than one year. RMI's analysis indicates this approach could enable 250 GW of new renewable energy without transmission upgrades, resulting in average national savings of $12.7 billion annually from 2025 to 2035. The brief highlights the role of the Inflation Reduction Act (IRA) and the Energy Infrastructure Reinvestment (EIR) program in making these projects financially viable and provides specific recommendations for regulators to ensure these savings reach customers through integrated resource planning and oversight.

The EESI 2023 Climate, Environmental, and Energy Congressional Hearings Tracker catalogs hearings across numerous House and Senate committees. House activity was led by the Natural Resources (28 hearings) and Energy and Commerce (24 hearings) committees, focusing on energy security, grid reliability, and critical minerals. Senate activity was prominent in the Environment and Public Works (22 hearings) and Budget (10 hearings) committees, with a strong emphasis on the economic costs of climate change, infrastructure resilience, and the implementation of the Inflation Reduction Act and Infrastructure Investment and Jobs Act.

The briefing discusses the gap between climate concern and action among Americans, identifying a lack of training and confidence as primary barriers. It highlights a framework for individual action across six domains—food, home energy, transport, shopping, influence, and citizenship—and argues that individual choices create ripple effects by normalizing low-carbon lifestyles, improving climate literacy, and sending market signals to businesses.

Since 1970, the coldest day of the year has warmed by an average of 7°F across 242 U.S. locations, with 97% of locations seeing a rise of at least 1°F. Winter cold snaps have also become shorter, decreasing by an average of six days in 97% of 244 analyzed locations. The most significant warming of coldest days occurred in the Ohio Valley (8.7°F) and Northwest (8.4°F) regions, with the highest individual increases recorded in Boise, Idaho (15.7°F) and Las Vegas, Nevada (14.3°F). These trends contribute to longer allergy and growing seasons, disrupted crop chill requirements, and altered water supplies.

The logistics sector is projected to grow from US$8.9 trillion to US$18.2 trillion by 2030, yet it currently accounts for 10 percent of global emissions. RMI proposes that G20 nations, which represent 80 percent of global CO2 emissions, lead the transition to sustainable logistics by implementing eco-driving and efficient packaging, establishing multi-level government regulatory frameworks, developing zero-emissions trucking corridors, and utilizing public-private partnerships and multilateral development organization financing to manage high capital risks.

2023 was the hottest year on record, reaching 1.4°C above the 1881-1910 baseline. This warming is driven by unprecedented levels of carbon pollution from fossil fuels, leading to more frequent and intense extreme weather events globally.

In 2023, the contiguous U.S. experienced its 5th-hottest year on record, with an annual average temperature 2.4°F above the 20th century average. The year saw a record 28 billion-dollar disasters, resulting in an estimated 492 lives lost and over $93 billion in damages. Severe storms were the primary driver, accounting for 68% of these events. The frequency of such disasters has increased significantly, with the average time between events dropping to 12 days in 2023, compared to 82 days in the 1980s.

The research evaluates the trade-offs between reducing hydropeaking to improve river ecology and the potential increase in CO2 emissions. Findings indicate that individuals generally prefer stronger restrictions on short-term regulations to benefit fish stocks, recreational use, and the ecological state, with these benefits outweighing the disutility of increased CO2 emissions. The study emphasizes the need to account for unobserved preference heterogeneity in willingness-to-pay estimations.

The SAVi assessment of the Tirana–Durres railway in Albania reveals that while the project is not economically viable under conventional financial metrics (BCR of 0.12), it is highly profitable from a societal perspective with a Sustainable Benefit-Cost Ratio (S-BCR) of 4.79. Over a 30-year period (2023–2053), the project is projected to generate cumulative discounted net benefits of EUR 270.34 million. The most significant financial gains come from avoided vehicle operating costs (EUR 96.79 million), followed by health benefits (EUR 44.93 million), time savings (EUR 44.39 million), and avoided accident costs (EUR 41.61 million). The report argues that integrating non-tangible social and environmental externalities—such as reduced CO2 emissions and improved public health—provides a stronger business case for sustainable transport infrastructure in Albania.

The briefing argues that conventional neoclassical financial analysis fails to account for long-term non-financial risks and externalities, often leading to underinvestment in sustainable transport. It proposes an 'integrated financial analysis' where positive externalities—such as health benefits and time savings—are monetized and converted into revenue streams. Using a case study of a Bus Rapid Transit (BRT) system in Bandung, Indonesia, the paper demonstrates that while the project is financially unviable based on ticket sales alone, it becomes viable if a small fraction (12% to 19%) of its societal externalities are internalized. The author recommends lowering social discount rates to better incentivize long-term sustainable investments.

The report evaluates the FAME II policy in India, finding that it generates significant net benefits by replacing internal combustion engine (ICE) vehicles with electric vehicles (EVs). Using the SAVi methodology, the analysis demonstrates that while the conventional benefit-cost ratio (BCR) remains constant at 1.58 across scenarios, the government's BCR increases as its subsidy contribution decreases. The highest cumulative net benefits (INR 1,606.90 billion) occur in the scenario with the lowest government contribution (25%), as this shifts more of the investment burden to consumers while still stimulating EV uptake. The primary drivers of these benefits are the avoided investment and operation costs of ICE vehicles and reduced fuel use, all of which are borne by users rather than the state.

A survey of 890 registered U.S. voters conducted in December 2024 reveals broad support for clean energy development and climate justice policies, though significant political polarization remains regarding the economic impact of the energy transition and specific regulatory measures. While majorities support the Paris Climate Agreement and the Inflation Reduction Act of 2022 (after reading a description), collective efficacy and active political advocacy for climate action remain relatively low.

A December 2024 survey of 890 registered U.S. voters reveals broad support for clean energy development and climate justice policies, though significant political polarization remains regarding fossil fuel production and the economic effects of the energy transition. While majorities support the Paris Climate Agreement and the Inflation Reduction Act of 2022, actual political advocacy and collective efficacy remain low.

The report finds that while a majority of registered U.S. voters support various clean energy policies and prefer candidates who take action on global warming, there is a sharp political divide regarding the issue's importance as a voting priority. Most voters support specific measures like soil restoration for farmers and clean energy job training, but few believe the U.S. government is responding well to the crisis. Support for the Inflation Reduction Act of 2022 is high after respondents read a description of the law, despite low general awareness.
