The report examines the implementation of the Brazilian Forest Code in Roraima, specifically the reduction of Legal Reserve requirements from 80% to 50% following the 2022 Ecological-Economic Zoning (ZEE-RR). It argues that this reduction, while legally permissible under certain conditions, acts as an 'invitation to deforestation' and risks setting a precedent for other Amazonian states like Amapá and Amazonas. The document highlights that approximately two million hectares in Roraima could lose legal protection, potentially releasing 267 million tonnes of carbon. It also notes that much of the state's public conservation units may lack the necessary land tenure regularization required by federal law to justify such a reduction.

The document analyzes the transition of heavy-duty gas turbines from natural gas to hydrogen, identifying critical engineering hurdles in combustion, thermal management, and materials. It evaluates current OEM solutions and concludes that while 100% hydrogen capability is technically feasible, commercial timelines depend on hydrogen availability for full-scale validation.

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 Midway Christian Church in Kentucky implemented a series of energy efficiency measures and solar installations between 2004 and 2018. These efforts included replacing an old HVAC system with heat pumps, installing LED lighting, and adding a 4.5-kW rooftop solar system. The church's journey was supported by the Green Chalice Program and Interfaith Power and Light, leading to its certification as a Green Chalice Congregation in 2014 and a commitment to reach carbon neutrality by 2030.

The document examines the limitations of traditional gender-blind cost-benefit analyses (CBAs) in transport planning and proposes a framework for integrating gender-disaggregated data and qualitative dynamics. Using a case study of a Non-Motorized Transport (NMT) plan in Coimbatore, India, it demonstrates how gender-sensitive mapping can reveal links between infrastructure, women's time poverty, and access to education. The author recommends that planners identify gender-specific dynamics via causal loop diagrams, improve the collection of disaggregated data, and monetize gender-specific outcomes to ensure investments do not inadvertently reinforce existing inequalities.

Tunisia faces stagnant economic growth, high youth unemployment, and a large informal sector despite strong human capital. The report identifies a 'Current Path' of slow growth and vulnerability to food price shocks and climate change, while proposing three alternative scenarios. These scenarios emphasize that improving governance, reducing inefficient subsidies, and enhancing education quality are foundational to any successful transition. The 'Sustainability & Equality' pathway is highlighted as the most effective for reducing extreme poverty and carbon emissions, while 'Going for Growth' offers the highest GDP increase through FDI and industrial promotion.

The report evaluates three development scenarios for Tunisia—'Going for Growth', 'Leapfrogging', and 'Sustainability & Equality'—against a baseline 'Current Path' for 2040. All three scenarios are projected to increase GDP and reduce extreme poverty, with 'Going for Growth' offering the highest GDP boost (30%) and 'Sustainability & Equality' providing the most significant reductions in extreme poverty, inequality, and carbon emissions. However, the report highlights critical trade-offs: 'Going for Growth' and 'Leapfrogging' are expected to increase carbon emissions and leave the country vulnerable to international food price shocks, while all scenarios must contend with increasing industrial, municipal, and agricultural water demand in a water-stressed environment.

The briefing advocates for a global Fossil Fuel Non-Proliferation Treaty based on three pillars: ending new exploration and production, phasing out existing production equitably, and enabling a just global transition. It outlines the necessity of international coordination to address the supply side of climate change, noting that current global production plans exceed 1.5°C limits. The document provides a roadmap for governments to support the treaty through public endorsements, diplomatic engagement, and domestic policy measures such as removing subsidies and restricting new infrastructure.

The briefing advocates for an international treaty to end the proliferation of coal, oil, and gas, phase out existing production equitably, and enable a global just transition. It outlines the necessary 'ingredients' for such a treaty, proposes specific diplomatic and domestic actions for governments, and provides suggested language for multilateral statements.

The briefing asserts that current climate frameworks, including the Paris Agreement, are insufficient because they focus on emissions (demand) rather than production (supply). It proposes a new legal instrument—a Fossil Fuel Non-Proliferation Treaty—to prevent the proliferation of fossil fuels, manage a fair phase-out where wealthy nations transition fastest, and ensure a global just transition for workers and communities. The document outlines building blocks for this cooperation, such as the Beyond Oil and Gas Alliance (BOGA) and a Global Registry of Fossil Fuels, and calls for governments to support the initiative and an ICJ Advisory opinion on climate change.

The briefing advocates for a Fossil Fuel Non-Proliferation Treaty to address the climate crisis by targeting the supply side of fossil fuels. It argues that existing frameworks like the Paris Agreement are insufficient because they focus on emissions rather than production. The proposed treaty would focus on three pillars: non-proliferation of new fuels, an equitable phase-out of existing production, and a global just transition. The document outlines necessary international cooperation, including new coalitions like the Beyond Oil and Gas Alliance (BOGA) and tools like the Global Fossil Fuel Register, while drawing parallels to successful treaties on nuclear weapons and landmines.

The assessment of Coimbatore's proposed Non-Motorized Transport (NMT) network reveals that while traditional benefit-cost ratios suggest the project is not investment-worthy, a sustainable valuation (S-BCR) shows a ratio of 4.75 per USD invested. The project, which involves 300 km of routes to be completed by 2035, is projected to generate a cumulative net benefit of USD 486.1 million between 2022 and 2045, primarily driven by avoided costs from traffic accidents and improved public health.

The SAVi assessment of Coimbatore's NMT plan, which involves 300 km of routes to be implemented by 2035, demonstrates that the project is highly profitable from a societal perspective. While a conventional benefit-cost ratio (BCR) suggests the project is not economically viable (0.47 to 0.50), the sustainable benefit-cost ratio (S-BCR), which includes externalities, ranges from 4.75 to 4.93. The largest individual benefit is the avoided cost of traffic accidents, valued at INR 30,144 million. Other significant gains include health benefits from physical activity and reduced fuel costs, although these are partially offset by the health costs of increased air pollution exposure for cyclists.

The Union of Concerned Scientists analysis finds that 48% of the rise in fire-danger conditions in western North America since 1901 and 37% of the cumulative burned forest area since 1986 are attributable to emissions from the 88 largest fossil fuel companies and cement manufacturers. In Arizona, over 10,000 wildfires burned nearly 2.5 million acres between 2017 and 2021, with the 2020 Bighorn Fire alone costing over $36 million. The document argues for holding these companies accountable and urges state governments to implement policies for forest health, community safety, and equitable resilience investments.

The document argues that major carbon producers are responsible for a significant portion of the increasing wildfire risk in western North America. It attributes 48% of the rise in fire-danger conditions since 1901 and 37% of the cumulative burned forest area since 1986 to emissions from 88 major fossil fuel and cement companies. In California, wildfires between 2017 and 2021 caused over $21 billion in economic damages and released an average of 53 million metric tons of CO2-equivalent annually. The report calls for corporate accountability, legal access to justice, and state-level policies to reduce emissions, improve forest health, and protect vulnerable communities.

In Colorado, over 5,000 wildfires burned more than 1 million acres between 2017 and 2021, including the record-breaking 2020 Cameron Peak Fire. The document argues that these companies should be held accountable for the costs of climate change and recommends that state governments implement policies to reduce human-ignited fires, increase forest health resources, and protect vulnerable communities.

The Union of Concerned Scientists finds that 37% of the cumulative burned forest area in western North America since 1986 is attributable to emissions from 88 of the world's largest carbon producers. The report links these emissions to a rise in vapor pressure deficit (VPD), which increases atmospheric 'thirst' and dries out vegetation, thereby amplifying wildfire risk. It argues that these corporations should be held legally and financially accountable for climate damages, including the costs of wildfire suppression and recovery.

The Union of Concerned Scientists analysis finds that emissions from the 88 largest fossil fuel companies and cement manufacturers are responsible for 48 percent of the rise in fire-danger conditions in western North America since 1901 and 37 percent of the cumulative burned forest area since 1986. In New Mexico, over 4,000 wildfires burned more than 800,000 acres between 2017 and 2021, with the 2022 Calf Canyon/Hermit’s Peak Fire becoming the state's largest on record. The document argues that these companies should be held accountable for the costs of climate change and recommends that state governments implement policies to reduce human-ignited fires, increase forest health resources, protect community health, and prioritize equitable investments for low-income communities.
