The report proposes optimizing the limited supply of sustainable aviation fuel (SAF) by targeting its use at airports with the highest contrail and particulate matter (PM) impacts. Analysis of 16.6 million flights in 2024 reveals that 2% of flights generate 80% of contrail-related warming. In the U.S., JFK, LAX, and O'Hare are identified as primary targets, while Heathrow, Istanbul Airport, and Paris CDG are the top candidates in Europe. The study finds that a 50% SAF blend can reduce LTO particulate emissions by 26-28% and contrail-related warming by 30-40%. While airport-wide targeting is simplest, time-based and flight-based strategies are more fuel-efficient. Implementation faces logistical hurdles, particularly at airports using hydrant fuel systems, but the report suggests these can be overcome through policy incentives and infrastructure investment.

The Clean Air Task Force asserts that the EU ETS review is critical for bridging the cost gap between conventional jet fuel and sustainable aviation fuels (SAF). While ReFuelEU Aviation established demand, the author notes that no large-scale e-SAF project in the EU had reached a final investment decision as of mid-2026. The document recommends extending the SAF allowance mechanism beyond 2030, mandating the reinvestment of ETS aviation revenues into sector decarbonisation, and carefully integrating high-quality carbon removals into the long-term strategy.

The document argues that relying solely on landfill gas capture and flaring is insufficient for methane mitigation. It highlights that gas capture systems often have a default recovery rate of about 50% and can fail due to poor design or maintenance, with some sites with capture systems exhibiting higher average emission rates than those without. The brief promotes organic waste diversion as the primary strategy to prevent methane generation at the source and suggests complementary solutions such as microbial methane oxidation systems (biocovers, biofilters, and biowindows) and improved operational practices like minimizing active working faces and enhancing cover systems. It further notes that while enclosed flares can exceed 98% destruction efficiency, open flares are more variable, and neither can eliminate methane that bypasses the collection system.

The Clean Air Task Force recommends that the EU increase its 2029 public procurement mandates for low-carbon steel to 50% and low-carbon concrete and mortar to 10%. It argues that the current IAA proposal is insufficient to drive investment and suggests expanding mandates to 100% by 2040. The report also proposes extending these requirements to private construction projects over 1000 m2 and private automotive fleets by 2032, while broadening the scope to include low-carbon plastics and fertilisers.

The Clean Air Task Force asserts that Europe faces an "untenable policy gap" regarding fusion energy despite the 2024 Draghi Report's call for an innovation strategy. While the US, China, Great Britain, and Germany are advancing regulations and public-private partnerships, the EU lacks a cohesive strategy to transition fusion from research to industrial application. The author advocates for a strategy that targets commercialisation in the 2030s, separates fusion from fission regulations, and utilizes public resources to de-risk common technological challenges. This call is supported by a broad ecosystem, including startups and Members of the European Parliament, who demand concrete timelines and funding commitments rather than mere intentions.

The brief contends that the Department of Defense is violating the Administrative Procedure Act and statutory obligations by refusing to conduct reviews for over 100 utility-scale wind projects. It argues this freeze is a pretext for the Trump Administration's animus toward wind energy, which will result in increased electricity prices, higher pollution levels, and greater greenhouse gas emissions.

The document is an open letter from energy systems researchers supporting the modernization of the GHGP scope 2 market-based method (MBM). The authors argue that the current MBM allows companies to claim zero emissions without a physical relationship between generation and demand, thereby failing as a legitimate value chain inventory and providing minimal real-world emissions impact. They advocate for the adoption of hourly matching, deliverability, and incrementality criteria to steer procurement toward new clean energy projects and technologies like energy storage and clean firm generation. While supporting the proposed updates, the signatories suggest strengthening them with an explicit age-based incrementality requirement to close gaps where legacy clean generators operate as merchant participants.

The United States has established a regulatory path for commercial fusion energy that avoids the frameworks used for nuclear fission reactors, instead adapting regulations for radioactive byproduct materials. Under the 10 CFR Part 30 framework, the Nuclear Regulatory Commission (NRC) and its Agreement State Program share authority, allowing compatible state agencies to license fusion facilities. The NRC is currently finalizing specific regulatory guidance in NUREG-1556, Volume 22, with a final rule expected by December 31, 2027. This proportional approach focuses on the confinement of radioactive materials, such as tritium, rather than fission criticality safety, aiming to provide the regulatory certainty needed for private investment and deployment.

The report outlines strategies for municipalities and national authorities in Latin America and the Caribbean to mitigate methane emissions from waste disposal sites through progressive operational improvements and organic waste diversion.

The report proposes a tripartite contracting model for Europe, where a state-backed intermediary connects clean energy suppliers and industrial consumers. This mechanism aims to solve structural barriers in bilateral Power Purchase Agreements (PPAs), such as creditworthiness requirements for SMEs and the mismatch between variable renewable generation and industrial baseload demand. By pooling diverse technologies—including renewables, storage, and clean firm capacity—the intermediary can offer 24/7 clean power products and absorb counterparty risk. The document outlines an implementation roadmap involving the European Commission and Member States, emphasizing the need for harmonized Guarantees of Origin, improved two-sided Contracts for Difference (CfDs) design, and integrated grid planning.

The report outlines a framework for federal agencies to optimize the delivery of energy incentives through three core principles: strategic planning, resource management, and communications. It suggests that agencies narrow their priorities, delegate decision-making, and involve industry early in program design to accelerate the commercialization of energy technologies. Specific recommendations include streamlining the application process for grants and loans, tailoring community benefit models to local needs, and providing transparent, phased guidance for tax credits to increase investor certainty.

The EU petrochemical industry, a €635 billion sector employing 1.2 million people, is facing a deep structural crisis characterized by ageing assets, high energy costs, and intensifying global competition. The industry is physically organized around approximately 150 chemical parks, with the Antwerp-Rotterdam-Rhine-Ruhr corridor serving as the world's densest concentration of production. However, the EU's global market share in chemical sales fell from 21% in 2009 to 13% in 2024, while China now accounts for 46% of global sales. The sector is experiencing a 'closure wave' of steam crackers—the central units for producing ethylene, propylene, butadiene, and aromatics—due to their 1970s-era scale and high carbon exposure under the EU ETS. Between 2022 and 2025, the industry lost approximately 37 Mt of production capacity, and investment CAPEX dropped from €7.6 billion in 2022 to €1.5 billion in 2025. The report highlights acute vulnerabilities in the supply of primary 'building block' molecules, noting that the EU produces less than 10% of global primary petrochemical capacity and is increasingly dependent on imports for molecules like methanol, where domestic production covers less than 15% of consumption.

The report outlines technical and operational measures to mitigate methane emissions from landfills in Latin America and the Caribbean (LAC), where waste management emissions accounted for 10,258 kt in 2023. It categorizes disposal sites into dumpsites, controlled landfills, and sanitary landfills, emphasizing that daily operational practices—such as waste compaction, daily cover application, and leachate management—significantly impact emissions even without advanced gas capture infrastructure. The document details specific equipment requirements, slope stability guidelines, and gas collection system designs, noting that while optimal capture efficiencies can exceed 80%, many regional facilities operate between 20% and 60%. Additionally, it advocates for organic waste diversion through composting and anaerobic digestion, drawing on European precedents, and stresses the necessity of multi-level capacity building for operators and policymakers to ensure sustainable mitigation.

The document outlines a comprehensive framework for LDAR programs, emphasizing that well-implemented programs can reduce methane leaks by nearly 80%. It details the technical application of OGI cameras, a structured nine-step survey process—from planning to data reporting—and a typology of common leak sources such as valves, flanges, and compressor seals. The guide also provides regulatory benchmarks for survey frequency, repair timelines, and reporting templates to ensure accountability and effectiveness in methane mitigation.

The document analyzes methane emissions in Algeria's oil and gas sector, estimating annual emissions at 2,304 kt. It finds that 41% of these emissions can be abated using low-cost technologies, with the highest potential coming from eliminating unlit flaring and implementing leak detection and repair (LDAR) programs. The analysis highlights that the lack of a dedicated methane regulatory framework and low domestic gas prices hinder mitigation, while the EU Methane Regulation presents a significant external driver for alignment to maintain market access.

The document analyzes methane abatement in Egypt's oil and gas sector, identifying a technical abatement potential of 35% of estimated emissions using four key technologies. All analyzed measures fall below a low-cost threshold of 596 USD/t CH4, with leak detection and repair (LDAR) and the elimination of unlit flaring offering the most significant opportunities. The analysis highlights that the economic viability of these measures depends heavily on the ability to monetize recovered gas, which is currently hindered by infrastructure gaps and low domestic gas prices. While Egypt lacks a dedicated methane regulatory framework, the document notes a recent agreement to develop a methane reduction roadmap and recommends prioritizing low-cost measures like LDAR and flaring monitoring in the near term.

The document analyzes methane emissions in Libya's oil and gas sector, estimating annual emissions at 1,221 kt. It finds that 55% of these emissions can be abated using four specific technologies—leak detection and repair (LDAR), vapor recovery units (VRU), replacing gas-driven pneumatic equipment, and improving flaring practices—all of which fall below a low-cost threshold of 596 USD/t CH4. The largest potential for reduction comes from eliminating unlit flaring in the onshore upstream segment. However, implementation is hindered by the lack of a dedicated methane regulatory framework, aging infrastructure, and import restrictions on specialized equipment. The report highlights that the EU Methane Regulation poses a future risk to Libyan exports starting in 2027, urging the adoption of flaring performance standards and financial incentives to meet a 2030 zero-flaring ambition.

The document analyzes methane abatement in Mexico's oil and gas sector, finding that 34% of estimated emissions can be reduced using low-cost technologies. While Mexico has a robust regulatory framework, implementation is hindered by enforcement capacity and infrastructure gaps. The most significant abatement potential lies in improving offshore flaring practices, while midstream leak detection and repair (LDAR) can offer negative abatement costs due to the monetization of recovered gas.

The document analyzes methane abatement in Nigeria's oil and gas sector, focusing on four technologies: leak detection and repair (LDAR), vapor recovery units (VRU), replacement of natural gas-driven pneumatic equipment, and improved flaring practices. It finds that 30% of estimated emissions (53.5 Mt CO2e) are technically abatable using these technologies, with 28% falling below a low-cost threshold of 596 USD/t CH4. The analysis highlights that the economics of abatement depend heavily on the ability to monetize recovered gas, with some measures showing negative costs. While Nigeria has a regulatory framework targeting zero routine flaring by 2030, implementation is uneven, particularly between onshore and offshore assets. The report recommends strengthening enforcement, developing measurement, reporting and verification (MRV) systems, and utilizing targeted financial instruments like concessional loans to overcome barriers such as high import costs and infrastructure gaps.

The report evaluates methane abatement in Algeria, Angola, Argentina, Brazil, Egypt, Ghana, Libya, Mexico, and Nigeria, focusing on leak detection and repair (LDAR), vapor recovery units (VRUs), improved flaring practices, and replacing gas-driven pneumatic equipment. Using a bottom-up marginal abatement cost curve (MACC) approach, the study finds that most mitigation measures fall below a low-cost threshold of 596 USD/tCH4 (20 USD/tCO2e). The economic viability of these measures is heavily dependent on the ability to monetize recovered gas, with LDAR and pneumatic equipment replacement often yielding negative marginal costs (net savings) when gas prices are sufficiently high. The report identifies significant structural barriers, including infrastructure gaps and limited local technical capacity, and recommends a combination of regulatory frameworks, targeted financial incentives, and infrastructure investment to accelerate deployment.
