The report examines the expansion of maritime activity in the Arctic, specifically the Northern Sea Route (NSR) and the Bering Strait, driven by climate change and Russia's strategy to monetize hydrocarbon reserves. It highlights a doubling of vessel transits in the Bering Strait since 2009 and warns of severe risks including oil spills, noise pollution, and disruptions to Indigenous subsistence activities. Despite geopolitical sanctions, the document argues that Russia's long-term commitment to Arctic infrastructure and the growing interest of 'near-Arctic' states like China will likely sustain the increase in traffic, necessitating urgent international cooperation and stricter shipping regulations to protect the fragile ecosystem.

In 2025, Global Witness verified the killings of 124 land and environmental defenders, continuing a trend of lethal violence primarily concentrated in Latin America. The report identifies land disputes and extractive projects as primary drivers, with a significant increase in the role of organized crime and hitmen. It highlights the vulnerability of Indigenous peoples and small-scale farmers, who comprise 75% of the victims. The document argues against individual-focused security models, instead promoting 'collective protection'—community-led systems like Indigenous Guards—and calls for the ratification of the Escazú Agreement and the repeal of laws used to criminalize activism.

Global Witness reports that 1,733 land and environmental defenders were killed between 2012 and 2021, with 200 deaths recorded in 2021 alone. The report identifies extreme land inequality, corruption, and the repression of civic space as primary drivers of violence, particularly affecting indigenous peoples in the Global South. It highlights critical situations in Mexico, Brazil, Colombia, and the Philippines, while advocating for the implementation of the Escazú Agreement and mandatory corporate due diligence in the EU to protect those on the front lines of the climate and biodiversity crises.

As of August 2022, India had installed 116 GW of renewable energy, achieving 66% of its 175 GW target for December 2022. While solar power is driving growth, with 9.8 GW installed between January and August 2022, wind energy installations have slowed. Progress is highly uneven across states; Gujarat, Telangana, Rajasthan, and Karnataka have met their 2022 targets, while Maharashtra, Uttar Pradesh, Andhra Pradesh, and Madhya Pradesh account for 61% of the national target shortfall. To reach the 2030 target of 450 GW, India must increase its monthly installation rate to 3.7 GW, which is 2.5 times the average rate seen in the first eight months of 2022.

Between 2000 and 2021, the U.S. experienced 1,542 major weather-related power outages, with 83% of all reported major outages attributed to weather. The average annual number of these events increased by approximately 78% in the 2011-2021 decade compared to 2000-2010. Severe weather, winter weather, and tropical cyclones were the primary drivers, with the Southeast, Midwest, and Northeast regions most affected. To address these vulnerabilities, the document suggests solutions such as microgrids, smart grid technologies, grid hardening, and bidirectional charging for electric vehicles.

Climate Central's analysis of U.S. power outage data from 2000-2021 reveals a significant increase in large-scale disruptions, with 83% of major outages attributed to weather-related events. The report highlights that the frequency of major outages rose by 64% between 2011-2021 compared to 2000-2010, driven by severe weather, winter storms, hurricanes, extreme heat, and wildfires. It emphasizes the vulnerability of aging infrastructure and the compounding effects of climate change, which simultaneously increases electricity demand for cooling while reducing the capacity of power plants due to water shortages. The report identifies the Southeast as the region with the highest number of outages and notes specific recent surges in Texas, California, and Michigan.

As of June 2022, there were 12,720 committed electric school buses across 38 US states, representing approximately 2-3% of the national fleet. California leads adoption, and while deployment is high in communities of color and areas with high PM2.5 pollution, it remains lower in the lowest-income school districts.

The document examines the increasing legal vulnerability of companies regarding plastic leakage into the environment. It highlights significant settlements for plastic pellet spills in the US and Europe, the potential for lawsuits against consumer brands and producers for macroplastic waste, and the role of economic losses—such as those in the fishing and tourism industries—in driving future strategic litigation.

Since 1970, fall temperatures in the contiguous U.S. have increased by an average of 2.7 °F, with warming observed in 97% of 245 analyzed cities. The most significant warming occurred in Nevada, Texas, and Arizona, with Reno, Nevada, recording the highest increase at 7.7 °F. This trend has led to a higher frequency of above-normal fall days, affecting 74% of analyzed cities. These temperature shifts extend health risks from extreme heat, prolong pollen and wildfire seasons, allow disease-carrying insects to persist longer, and disrupt ecological events such as bird migrations and fruit ripening.

The 2022 outlook for the news industry emphasizes a period of consolidation following the COVID-19 crisis, with a strategic shift toward subscription models, digital audio, and AI-driven efficiency. While media leaders express confidence in their own companies, they remain concerned about societal polarisation and the financial viability of local news. The industry is pivoting toward youth-oriented platforms like TikTok and Instagram while struggling to effectively communicate the complexities of climate change to mainstream audiences.

Climate Central analysis reveals that 83% of 241 analyzed U.S. cities saw an increase in summer stagnant days between 1973 and 2021, with a strong positive correlation between these events and rising summer high temperatures. Annual stagnation has also increased in 81% of these cities, with hotspots in Southern Texas and coastal California. These trends are expected to worsen with climate change, potentially adding up to 40 more stagnant days per year by late-century, which traps pollutants and disproportionately affects communities of color due to historical housing policies.

Since 1970, average summer nights in the contiguous U.S. have warmed by 2.5°F, with nighttime temperatures warming nearly twice as fast as daytime temperatures since 1895. Using the Climate Shift Index (CSI), Climate Central finds that climate change makes warm summer nights significantly more likely than warm days, posing health risks and increasing cooling costs.

The document argues that achieving a sustainable future requires 'decoupling' economic growth from resource use and waste. While the global transition toward renewable energy reduces fossil fuel reliance, it increases the demand for critical minerals and creates new challenges regarding e-waste. For Africa, this transition presents opportunities for industrialization and green technology adoption, but risks include stranded assets, economic marginalization, and governance failures in the mining sector.

Analysis of 246 U.S. locations shows that 74% have experienced an annual increase in extremely hot days since 1970, with Austin, TX seeing the largest increase. The document highlights that extreme heat risks are higher in traditionally cooler regions due to lack of acclimatization and infrastructure, and that vulnerable populations including children, seniors, and low-income households are disproportionately affected.

The report analyzes Tunisia's health landscape, noting a transition from communicable diseases to non-communicable diseases (NCDs) as the primary cause of death. While life expectancy is projected to reach 79 years by 2040 and maternal mortality is declining, the country faces rising challenges from obesity, tobacco use, and road traffic accidents. The report warns that the mortality burden from injuries will surpass that of communicable diseases by 2025 and that the primary healthcare system remains ill-equipped to manage the increasing cost and complexity of NCDs.

This report update by the Climate Policy Initiative tracks the growth and evolution of climate commitments by private financial institutions to align with the Paris Agreement and achieve net zero emissions by 2050, specifically analyzing trends following COP26.

The Net Zero Stocktake 2022 finds that while net zero target setting has expanded significantly—particularly among national governments and large companies—there is an 'alarming lack of credibility' across the landscape. Fewer than one-fifth of national and sub-national targets meet minimum procedural robustness standards, and 65% of corporate targets similarly fail these standards. The report highlights a widespread lack of transparency regarding the use of external offset credits and a deficiency in covering Scope 3 emissions among companies.

The Net Zero Stocktake 2022 finds that while net zero target setting is becoming nearly universal at the national level and increasing among corporations and cities, a significant lack of credibility and robustness persists. Fewer than one-fifth of national and sub-national targets meet minimum procedural standards, and 65% of corporate targets fail these same standards. The report highlights a widespread lack of transparency regarding the use of external offset credits and a deficiency in Scope 3 emissions coverage among companies.

The document analyzes the growth of commercial aviation and its contribution to climate change. It details the composition of aircraft emissions, the significant warming effect of contrail-induced cirrus clouds, and the projected recovery of air traffic following the COVID-19 pandemic. While aircraft efficiency has improved, the overall volume of passengers and freight is expected to increase, potentially tripling emissions by 2050. The brief also discusses regulatory efforts, such as ICAO's CO2 standards, and the disproportionate per capita fuel consumption in the United States.

The global GSS+ bond market reached a cumulative issuance of $3 trillion by Q1 2022, despite a nearly 30% year-on-year decline in quarterly issuance due to interest rate hikes and the Russia-Ukraine war. While green and social bonds saw significant decreases, sustainability-linked bonds (SLBs) grew by over 100%, with 61% of their KPIs linked to greenhouse gas emission targets. China led global green bond issuance in Q1 2022, and the period saw the emergence of the first sovereign SLB from Chile and the first public sector SLB from the city of Helsingborg.
