The Independent Integrity Unit (IIU) report details its activities from January to June 2024, focusing on four strategic objectives: fostering a culture of integrity, acting as a thought leader in climate finance integrity, serving as a trusted investigation mechanism, and utilizing technology for data-informed decision-making. Key achievements include the launch of an e-learning module for Accredited Entities, the conduct of a regional capacity-building workshop in Morocco for African entities and CSOs, and the opening of 17 new cases. The unit also advanced its policy framework by drafting guidelines for Administrative Remedies and Exclusion (ARE) and managing conflicts of interest for external panel members.

Climate change is increasing the frequency of nighttime temperatures exceeding 18°C, 20°C, and 25°C, which impairs human sleep and increases health risks. Between 2018 and 2023, the average person globally experienced 4.8 additional days per year above 20°C and 11.5 additional days above 25°C due to climate change. The report highlights severe impacts in specific regions, such as California in the U.S. and West Bengal and Assam in India, where the number of added hot nights is highest.

Using the Climate Shift Index (CSI), Climate Central found that human-caused climate change significantly boosted spring warmth in 2024, affecting 300 million people in the U.S. and approximately one in four people globally. The strongest influence was observed in coastal and island regions, such as Puerto Rico and Florida, while areas with the highest temperature anomalies, like the Upper Midwest, showed lower CSI levels due to higher historical temperature variance.

The report highlights that the EU is a net importer of CO2 emissions, with consumption-based emissions (CBEs) significantly exceeding territorial emissions. While the EU has focused on territorial targets, the authors argue that addressing CBEs is essential for global climate goals. Through case studies of Sweden, Denmark, and France, the report identifies a lack of standardized monitoring and binding targets as primary barriers. It recommends that the EU establish binding CBE targets, standardize carbon accounting, and expand policies like the Carbon Border Adjustment Mechanism (CBAM) and the EcoDesign Regulation to drive sustainable consumption and production globally.

Analysis of 241 U.S. locations from 1970 to 2023 shows that 95% have experienced warming average summer temperatures, with an average increase of 2.5°F. The Northwest, Southwest, and South regions saw the most significant heating. Additionally, 58% of analyzed locations now experience at least 14 more above-normal summer days than in 1970. The document also highlights the health risks of extreme heat, particularly for vulnerable populations and those affected by urban heat islands, and provides a directory of monitoring tools and hurricane season resources.

In April 2024, fossil fuel generation in the EU fell to a record monthly low of 23%, with coal and gas both seeing significant declines. This shift was driven by record-high wind and solar output, which together provided 34% of electricity, and a recovery in hydropower. Consequently, the EU power sector's emissions in April reached a record low of 38 million tonnes of CO2, contributing to an 18% year-on-year decrease in emissions for the first four months of 2024 despite a slight recovery in electricity demand.

Between 2000 and 2023, 80% of major U.S. power outages were caused by weather, with a significant increase in frequency during the last decade. Severe weather, winter storms, and tropical cyclones are the primary drivers, with Texas and the Southeast region among the most affected. The document highlights the vulnerability of aging infrastructure and the disproportionate impact on marginalized and medically vulnerable populations, while suggesting grid hardening, microgrids, and emissions reductions as paths toward resilience.

The U.S. experienced a record 28 billion-dollar disasters in 2023, causing over $93 billion in damages. Since 1980, tropical cyclones have been the costliest events, while severe storms are the most frequent. The document details how warming temperatures intensify specific hazards—such as increasing rainfall intensity and fueling stronger tropical cyclones—and notes that the average time between such disasters has shrunk from 82 days in the 1980s to 12 days in 2023.

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 document reports that 2023 is virtually certain to be the hottest year on record, with global surface temperatures from January to November 2023 ranking highest in the 144-year record at 1.4°C above the 1881-1910 baseline. In the U.S., 25 billion-dollar weather and climate disasters occurred between January and November 2023, surpassing the previous annual record of 22 in 2020. These events caused an estimated 482 deaths and $81 billion in damages, with severe storms accounting for 76% of these disasters. The average time between such disasters in 2023 dropped to 10 days, compared to 82 days in the 1980s.

An analysis of 241 U.S. locations from 1970 to 2022 shows that 82% experienced rising November temperatures, with an average increase of 2.1°F.

The research finds that a higher number of climate policies is associated with lower projected emission change rates up to 2030, a result that remains robust when controlling for GDP, historical emissions, and the rule of law. The study identifies specific policy gaps based on emission trends: countries with fast-increasing emissions lack policies in energy-demand sectors like buildings and transport, while those with stalling emissions lack cross-sectoral climate strategies. Across all groups failing to reduce emissions, there is a notable deficiency in policies targeting the reduction of energy and material demand.

Analysis of 241 U.S. locations shows that 95% have experienced summer warming since 1970, with an average increase of 2.4°F. The West, Southwest, Northwest, and western Texas saw the most heating, with Reno, Nevada, recording the highest increase at 11.1°F. Additionally, 58% of analyzed locations now experience at least two more weeks of above-normal summer days than in 1970. The document highlights that excessive heat is the leading cause of weather-related deaths in the U.S. and disproportionately affects vulnerable groups, including children, the elderly, and people of color living in urban heat islands.

The DR Congo faces exceptionally high levels of extreme and multidimensional poverty, with forecasts suggesting it will fail to meet 2030 Sustainable Development Goals on its current path. Despite modest declines in extreme poverty between 2005 and 2018, the country remains one of the world's poorest, with significant regional variations and a growing urban poverty phenomenon.

Analysis of 150 U.S. weather stations shows that 91% experienced an increase in hourly rainfall intensity between 1970 and 2022, with an average increase of 13%. This trend is linked to climate warming, which allows the atmosphere to hold more moisture, increasing the risk of flash flooding and landslides regardless of whether a location is typically wet or dry.

As of December 2022, there are 5,612 committed electric school buses in the US, a significant increase driven largely by the EPA's Clean School Bus Rebate Program. While California leads in total numbers, adoption has expanded to all 50 states and is increasingly concentrated in low-income and minority communities, though the report emphasizes the need for continued focus on equity and infrastructure support.

In 2022, China's power demand grew by 4.4% (374 TWh), with wind and solar generation increasing by 26% to meet 69% of the net demand increase. Despite this clean energy growth, coal generation reached an all-time high in absolute terms (5,420 TWh), though its share of the electricity mix fell to 61%. Since 2000, China's total power sector emissions have increased fivefold to 4,694 MtCO2, even as emissions intensity declined by 21%. To reach a net zero power sector by 2040, China would need to reduce emissions by 261 million tonnes of CO2 annually.

In 2022, wind and solar reached a record 12% share of global electricity, driving carbon intensity to a record low of 436 gCO2/kWh. However, absolute power sector emissions reached an all-time high of 12,431 mtCO2 because clean power growth did not fully meet rising global demand, which grew by 2.5% (+694 TWh). While coal generation rose by 1.1% to a record 10,186 TWh, the report forecasts that 2023 could be the first year of structural decline in fossil generation and the peak for power sector emissions. The analysis highlights a significant gap between current growth and the IEA NZE pathway, which requires wind and solar to reach 41% of global generation by 2030.

The Independent Integrity Unit (IIU) report details its activities from September 2022 to February 2023, focusing on investigation efficiencies, policy development, and risk mitigation. During this period, the IIU opened nine new cases, including three project-related and six staff misconduct cases, while closing 11 cases in total. Key operational advancements include the development of a draft Investigation Manual, the issuance of three Management Implication Reports, and the creation of an automated referrals tracker for Accredited Entities and Delivery Partners. The Unit is also operationalising the Administrative Remedies and Exclusion (ARE) Policy through four secondary documents. To enhance risk detection, the IIU expanded its machine learning capabilities, integrating significantly more data into its Integrity Due Diligence Platform and applying a Red Flag Detection Workflow to the Readiness Programme. Additionally, the IIU provided technical assistance to Mongolia and engaged in international forums at COP27 to discuss the intersection of corruption and climate change.
