The document details how human activities, primarily the burning of fossil fuels, have increased atmospheric concentrations of carbon dioxide, methane, and nitrous oxide to levels higher than any point in the last 800,000 years. These gases have caused a combined 1.6°C of global warming since 1850, with CO2 and methane accounting for 95% of this increase. In the United States, 76% of greenhouse gas emissions originate from three sectors: transportation (28%), electric power (25%), and industry (23%). The text emphasizes that while the U.S. has reduced emissions to approximately 17% below 2005 levels, the pace of reduction must more than triple to meet 2030 national targets.

The report examines the impact of methane emissions from global coal mining, noting that methane is 82.5 times more powerful than carbon dioxide over 20 years. It highlights a systemic failure in reporting, where governments rely on 'bottom-up' estimates that can underestimate emissions by a factor of 30, while operators possess precise data for safety reasons but are rarely required to share it. Despite the Global Methane Pledge, only the EU and Canada have committed to specific actions for active coal mine methane reduction.

A CIEL analysis finds that 118 planned or underway petrochemical projects in the US could add 153.8 million metric tonnes of CO2 equivalent emissions annually, potentially increasing the sector's share of US greenhouse gas emissions from 5.2% to over 7%. The report highlights that ten megaprojects account for half of these potential emissions and that ammonia production is a significant growth area, with 95% of proposed US ammonia production derived from methane gas. Furthermore, the buildout is concentrated in already polluted areas like Louisiana's "Cancer Alley" and the Ohio River Valley, deepening environmental injustices.

This policy brief argues that the current reliance on a single 100-year metric for greenhouse gas emissions obscures the distinct warming impacts of methane and carbon dioxide. The author advocates for a "multi-basket" approach with separate targets and dual metrics to address both short-term and long-term climate risks, asserting that simultaneous mitigation of both pollutants is essential to meet global temperature targets and reduce climate overshoot.

A group of Canadian physicians and healthcare professionals is calling for the immediate implementation of a strong emissions cap on the oil and gas sector, arguing that such a measure is critical for both climate mitigation and public health. They advocate for a 45% reduction in emissions below 2005 levels by 2030, asserting that the current proposed framework is insufficiently ambitious. The authors highlight that the oil and gas sector is Canada's largest source of greenhouse gas pollution and that reducing these emissions would significantly lower levels of dangerous air pollutants like NO2, PM2.5, and ozone, potentially preventing thousands of premature deaths and providing billions in economic benefits.

The Net Zero Stocktake 2024 reveals a consolidation of net zero targets across countries, cities, and companies, but highlights a critical gap in integrity. While national targets now cover 87% of global GHG emissions, fewer than 5% of non-state entities meet all minimum procedural and substantive integrity criteria. The report emphasizes that national targets often act as a 'ceiling' for subnational ambition, though some regions in countries like Australia and Japan have historically pushed national goals forward. It also notes that members of the Race to Zero campaign generally outperform non-members on integrity measures, although absolute performance remains low.

The report examines the intersection of climate change and democratic processes, detailing how extreme heat, floods, and wildfires disrupt voter registration, polling access, and ballot counting. It provides evidence of recent climate-driven disruptions in the US, India, and Pakistan, and analyzes temperature anomalies in 60 countries during the 2024 election cycle. The authors advocate for systemic changes, such as flexible voting arrangements, improved risk mapping, and updated emergency statutes, to protect the fundamental right to vote on a warming planet.

The OCI+ tool reveals that global oil and gas resources vary by up to five times in life-cycle emissions intensity. The document emphasizes that supply-side emissions from production, refining, and transport can rival end-use consumption, making the identification of high-emitting assets critical for short-term climate action. It highlights methane reduction as the highest priority, noting that methane accounts for over half of operational emissions and advocating for the use of a 20-year global warming potential (GWP20) to accurately assess climate risks.

The OCI+ tool provides data on the methane intensity of global oil and gas resources, highlighting that the sector is responsible for an estimated one-third of global methane emissions. The tool aims to help policymakers, investors, and civil society prioritize the highest-emitting assets for mitigation. The document emphasizes that over half of industry methane emissions can be profitably reduced and notes the role of satellite monitoring in identifying super-emitters. Additionally, the OCI+ includes an environmental justice feature to map the risks posed by gas flaring to nearby communities, specifically utilizing 2022 US flaring data.

The webinar 'Youth Action for Climate and Clean Air Now' brought together over 140 youth leaders and experts to discuss the role of young people in mitigating short-lived climate pollutants (SLCPs) and improving air quality. Key discussions focused on the science of 'super pollutants' like methane and black carbon, the importance of youth engagement in the 2025 Nationally Determined Contribution (NDC) update process, and the implementation of community-led solutions such as solar dryers in Ghana and indoor air quality monitoring in UK schools. The event emphasized that reducing SLCPs can provide rapid climate benefits and improve public health, particularly for children in the global south who are disproportionately affected by pollution.

The report analyzes seven categories of enclosure-based and open measurement methods for greenhouse gas emissions in sanitation systems. It finds that while enclosure-based methods like flux chambers are widely used, they are limited by scale. Emerging optical and remote sensing methods offer broader coverage but are constrained by high costs. The document highlights a critical lack of empirical data for non-sewered sanitation in low- and middle-income countries and advocates for standardized, affordable methodologies and increased collaboration to improve national greenhouse gas inventories.

The document argues that the EU's territorial emission reductions underestimate its true carbon footprint due to emissions embedded in imports. It identifies food, housing, and mobility as primary consumption 'hotspots' and calls for a shift from a focus on production efficiency to policies that target consumption patterns and behavioral change. Key barriers include a lack of standardized monitoring and supply chain transparency, while opportunities lie in leveraging the EU's market influence to set common CBE targets and support developing countries in transitioning to low-carbon production.

The document argues that relying on soil carbon sequestration to offset livestock emissions is risky due to finite storage capacity, the reversibility of carbon storage, and the significant warming potential of methane and nitrous oxide, which can outweigh sequestration gains.

The document analyzes the South African beef industry's 'system of provision' to argue that current 'market-centred' transition policies—which prioritize growth and technical intensification—fail to address deep-seated inequalities and the vulnerabilities of farm workers and smallholder farmers. It highlights the industry's high greenhouse gas emissions and the disproportionate impact of climate change on marginalized producers. The authors advocate for a transformative just transition that integrates labor reform, agrarian reform, and a shift away from corporate-led governance toward democratic, socio-ecological sustainability.

The report critiques the GWP* (Global Warming Potential Star) metric, arguing that while it may be useful for specific climate modeling, its application to national or sectoral policy is unfair and scientifically misleading. Unlike the standard GWP, which uses a zero-emission baseline, GWP* evaluates current emissions relative to past levels, potentially rewarding countries with historically high emissions and penalizing developing nations. The authors contend that this approach can be used to justify continued methane pollution, particularly in the livestock sector, and advocate for a 'multi-basket' approach that sets separate targets for short-lived pollutants like methane and long-lived gases like CO2 to ensure equitable and effective climate action.

The guide argues against one-size-fits-all climate action lists, instead encouraging individuals to audit their own habits in four key areas: diet, electricity use, travel, and home temperature regulation. It highlights the environmental impact of agriculture, fossil-fuel electricity, and transportation, offering specific practical steps—such as shifting to plant-rich diets, upgrading to LED bulbs, and reducing air travel—to lower personal greenhouse gas emissions.

Between 2019 and 2023, agribusiness interests spent over $523 million lobbying on the US food and farm bill, with spending peaking in 2023. The report highlights the role of the American Farm Bureau Federation (AFBF) in opposing climate action and environmental regulations while advocating for commodity subsidies. It recommends that Congress prioritize small and marginalized farmers and strengthen antitrust enforcement to curb corporate power.

Since 1970, 98% of analyzed U.S. cities and all 50 states have warmed, with Reno, Nevada and Alaska experiencing the fastest increases. To combat this, U.S. clean technology investment reached a record $239 billion in 2023, more than tripling since 2018, with South Carolina and Nevada leading in investment as a percentage of GDP, primarily driven by battery manufacturing.

The guide describes how spectrometers on satellites detect the infrared signature of methane to identify emissions from oil and gas, coal, waste, and agriculture. It highlights the emergence of NGO-led missions like MethaneSAT and Carbon Mapper, which provide open-source, granular data to drive climate action and pressure emitters to reduce leaks.

The Europe Gas Tracker Report 2024 finds that Europe is continuing a massive gas infrastructure buildout despite emerging from its energy crisis and seeing a decline in gas demand. With €84.1 billion in planned LNG terminals and pipelines, the report argues that the region is creating significant overcapacity and risking stranded assets. It further warns that these projects could increase annual emissions by up to 1.1 gigatonnes CO2e, undermining the EU's 'Fit for 55' goals. Additionally, the report characterizes the proposed 35,000 km hydrogen pipeline network as a 'red herring' that may serve to lock in methane gas infrastructure due to technical incompatibilities and the lack of green hydrogen production.
