Greenhouse gas mitigation scenarios for major emitting countries
The report finds that greenhouse gas emissions in 26 major emitting countries and regions are projected to remain above 2005 levels in most cases by 2030 under current policies. While 16 of these entities are on track or close to meeting their original NDC targets, 11 are off-track to meet their updated targets, and five have not yet submitted updates.

Climate impacts in southern Africa during the 21st Century
The report identifies southern Africa as a climate change 'hotspot' where warming in the interior is occurring at approximately twice the global average rate. It warns that global warming of 3 °C could lead to the collapse of key crops and the livestock sector. Freshwater availability is projected to decline due to reduced rainfall and increased evaporation, while the risk of multi-year droughts and intense heat waves is expected to rise. These changes threaten food security, increase human mortality in urban areas, and place thousands of unique species at risk of premature extinction. The document emphasizes that the severity of these impacts depends on global mitigation efforts, with 'low mitigation futures' posing significantly higher risks than those limiting warming to 1.5 °C or 2 °C.

wind energy
The U.S. experienced significant growth in wind electricity generation between 2000 and 2020, with wind turbines accounting for 8.4% of total utility-scale electricity generation. Research from Net Zero America's 'High Electrification (E+)' scenario suggests that by 2050, Texas could lead the country with over 180 gigawatts of installed capacity, while Missouri, Iowa, Illinois, and Nebraska could each exceed 100 gigawatts. Offshore wind potential is particularly high along the East Coast, with Environment America estimating a potential for over 7,200 terawatt-hours of electricity per year. The document also highlights job growth potential, noting that Texas could support over 130,000 wind energy jobs by 2050, and rural states like Wyoming, Nebraska, Montana, and Iowa could see more than 200 jobs per 10,000 residents.

AFFORDABLE HOUSING AT RISK: Threats from Coastal Floods and Sea Level Rise
The document reports that Florida's affordable housing stock is the 5th most vulnerable in the United States to future coastal flooding. By 2050, 963 units (0.8% of the state's stock) are projected to face at least annual threats, representing a 774% increase from 2000. Specific high-risk areas include Miami Beach, Marathon, and Ft. Lauderdale, with Miami Beach ranked 11th nationwide for units at risk. The analysis notes that affordable housing is particularly vulnerable because it is often older, of poorer quality, and lacks resilience features like flood-proofing.

2020 Cooling Degree Days
Climate Central's analysis of 242 U.S. cities shows that 96% have experienced an increase in cooling degree days since the 1970s, with the most significant rises in the South and Southwest. This trend is driving a projected 59% increase in residential air conditioning consumption by 2050, which contributes to carbon emissions, the urban heat island effect, and the release of heat-trapping gases from improper disposal.

Beyond national climate action: the impact of region, city and business
The analysis assesses the impact of commitments from 79 regions, approximately 6,000 cities, and nearly 1,600 companies within ten major emitting economies. If fully implemented, these individual commitments could reduce 2030 emissions by 3.8%–5.5% compared to current national policy projections. The study finds that such action could lead the European Union, Japan, and India to overachieve their nationally determined contributions (NDCs), and could serve as a primary driver for climate action in the United States following national policy rollbacks.

Sustainable Investing: Shaping the future of finance
Sustainable investing is transitioning from a niche approach to a mainstream financial practice, with global assets under sustainable mandates projected to reach USD 160 trillion by 2036. While adoption is increasing in developed countries, the sector faces challenges regarding capacity at financial institutions and the integration of sustainability into passively managed portfolios. Key future drivers include the centrality of climate risk, the guidance provided by the Sustainable Development Goals (SDGs), and the development of innovative financial instruments.

Plastic & Climate: The Hidden Costs of a Plastic Planet
The report details how plastic production, refining, waste management, and environmental degradation contribute significantly to global greenhouse gas emissions. It warns that by 2050, cumulative emissions from plastic could consume 10–13 percent of the remaining carbon budget, potentially making the 1.5°C climate target impossible to achieve. The document advocates for ending single-use plastics and stopping the expansion of petrochemical infrastructure to mitigate these impacts.
