The policy brief advocates for linking the U.S. Department of Energy's (DOE) Regional Clean Hydrogen Hubs with clean transportation corridors for heavy-duty trucking and marine shipping. It argues that while hubs provide localized production, corridors act as 'spokes' that expand the market beyond industrial off-takers and improve the economic viability of zero-carbon fuels. The author suggests that coordinating these programs will create a synergistic ecosystem, reduce conventional air pollutants in environmental justice communities, and position the U.S. as an exporter of low-emissions ammonia.

A coalition of environmental organizations urges the EPA to prioritize MERP funding for enhanced monitoring, compliance assurance, and the permanent plugging of marginal conventional wells, while limiting financial assistance to private operators.

The report assesses Europe's theoretical CO2 storage capacity, estimating it between 262 and 1520 GtCO2, and matches this against industrial and non-industrial CCS demand scenarios for 2035 and 2050. It compares 'Export' scenarios (limited key basins) with 'Domestic' scenarios (widespread storage), finding that while Europe has sufficient long-term theoretical capacity, current announced projects are insufficient for 2035 demand. The analysis highlights that widespread domestic storage could halve transport CAPEX costs compared to export-heavy models, though certain regions like Northern Italy, the German North Sea, and Switzerland may face capacity constraints under high-demand scenarios.

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.

Methane mitigation is severely underfunded, with current annual spending at only 10% of the $119 billion required to keep global warming below 2 degrees Celsius. The report identifies structural barriers, including a lack of donor prioritization, absence of dedicated funding windows, and a shortage of bankable project pipelines in developing countries. It recommends that development finance institutions designate methane 'champions', that donor governments increase funding for project preparation, and that developing nations create enabling policy environments to attract private investment.

The report asserts that the EU cannot reach net zero by 2050 without large-scale deployment of CCUS, estimating a need to capture and store between 300 and 640 Mt of CO2 annually by 2050. It highlights a significant gap between current project announcements and the necessary infrastructure, particularly in CO2 transport and geological storage. The authors recommend that the European Commission establish clear targets, a regulatory framework for CO2 grids, and financial mechanisms like Carbon Contracts for Difference (CCfD) to de-risk investments. The document specifically identifies 'hard-to-abate' sectors—such as cement, steel, and waste-to-energy—as critical areas where CCUS is either the lowest-cost or only viable decarbonisation pathway. It also emphasizes the necessity of technology-based carbon dioxide removals (CDR) via BECCS and DACS to balance residual emissions.

The Clean Air Task Force asserts that while the Net Zero Industry Act (NZIA) strengthens the EU's manufacturing capabilities for net-zero technologies, the slow pace of infrastructure deployment—such as power lines and pipelines—could become a "fatal bottleneck." The authors propose three primary adaptations of NZIA policies for infrastructure: integrating clean energy infrastructure into spatial planning and mapping, implementing upper limits on permitting timelines for non-renewable net-zero technologies like advanced nuclear, and establishing "one-stop shop" administrative agencies to streamline permitting processes, citing Denmark as a potential model.

The document advocates for a diverse energy mix that includes 'clean firm power'—non-weather-dependent zero-carbon sources—to complement wind, solar, and battery storage. It argues that relying solely on variable renewables would lead to excessive costs, land use, and infrastructure requirements, while a diversified approach could significantly reduce the time and cost of the energy transition.

The report evaluates the potential for offshore carbon capture and storage (CCS) in the US mid-Atlantic to compensate for limited onshore capacity. Using the SimCCS modeling toolset, the study identifies 199 facilities across 15 industry sectors with a total of 31.47 Mt of annual capturable CO2. It finds that while offshore storage capacity is vast—estimated at 621,221 MtCO2 across 125 candidate sites—the costs are significantly higher than onshore benchmarks, ranging from 95.5 to 147.9 $/tCO2. This cost disparity is primarily driven by offshore pipeline installation and storage expenses. The analysis suggests that capturing the full 31.47 MtCO2 would require a 7,789 km branched pipeline network and that emission prices between $95.5 and $103.5 per tonne could incentivize initial capture efforts.

The Clean Air Task Force conducted a survey of over 430 oil and gas sites across 15 European countries between February 2021 and March 2023, finding that methane pollution is widespread, with emissions detected at 289 of the visited sites.

A coalition of environmental organisations is calling on the European Parliament to reject amendments 268-280 to the Methane Regulation, arguing these changes would create loopholes for large companies, reduce the frequency of leak detection and repair (LDAR) inspections, and weaken reporting requirements for energy imports.

The Clean Air Task Force asserts that the EPA has a 'golden opportunity' to dramatically reduce climate pollution by mandating carbon capture and sequestration (CCS) for baseload power plants. Citing Department of Energy (DOE) data, the document notes that CCS costs have declined since 2015 and are further offset by the Inflation Reduction Act's expanded 45Q tax credits, which increased the credit to $85/tonne for power generation facilities storing CO2 in saline geologic formations. The author contends that CCS represents the 'best system of emission reduction' and that failing to implement these standards would result in significant harm to public health and welfare.

The authors contend that the U.S. EPA has sufficient evidence to base CO2 emissions standards on carbon capture and sequestration (CCS) technology. They draw a parallel to sulfur dioxide scrubbers, which were rarely used before 1971 but became industry standard after emissions regulations were implemented. The text highlights that while only four U.S. power plants currently use carbon scrubbers, the historical example of sulfur scrubbers shows that regulation can rapidly increase vendor availability, lower costs through 'learning by doing', and significantly increase pollution removal efficiency.

The review finds that energy transition modeling in Africa is a rapidly growing field, yet it is dominated by researchers based outside the continent and largely ignores the nexus between decarbonization and socio-economic development. Most models focus on global targets (2030/2050) and techno-economic optimization, while neglecting political constraints, comprehensive transition costs, and a diverse range of low-carbon technologies like nuclear and carbon capture.

Clean Air Task Force (CATF) conducted a multi-country survey of over 430 oil and gas sites across 15 European countries between February 2021 and March 2023 using optical gas imaging (OGI). The survey found evidence of methane emissions at 289 sites, identifying 881 sources of emissions. The report highlights that emissions occur at every stage of the supply chain, with storage tanks, vent stacks, unlit flares, and piping leaks being the most common sources. It specifically notes significant maintenance failures in Romania and continuous venting at various compressor stations across the bloc. CATF argues that voluntary industry commitments and self-reporting are insufficient, as observed emissions often contradict corporate claims. The report recommends that the EU adopt a comprehensive LDAR program, ban routine venting and flaring, establish a mandatory monitor, report, and verify (MRV) system, implement tough import standards for fossil fuels, and create a program to remediate abandoned wells.

A coalition of organizations urges the US government to maintain conservation funding, expand research into biomass carbon removal and storage (BiCRS), and accelerate the USDA's adoption of new conservation practices that reduce greenhouse gas emissions and improve soil carbon.

The document asserts that nuclear energy is essential for a decarbonized global energy system to provide 'clean firm' power, reducing reliance on over-built variable renewables and expensive long-duration storage. It identifies a 'profoundly dysfunctional' current delivery model characterized by high costs and delays, exemplified by the Vogtle 3 and 4 projects in Georgia. To achieve a target build rate of hundreds of Gigawatts per year, the author proposes transitioning from bespoke construction projects to standardized, commoditized 'products' with capital costs below $4,000/kw and delivery times of 3-5 years. Key recommendations for U.S. policy include reforming the Nuclear Regulatory Commission (NRC) to adopt performance-based licensing, establishing a 'sandbox' for testing new designs, creating an International Bank for Nuclear Infrastructure, and ensuring the domestic availability of high assay low enriched uranium (HALEU).

A coalition of environmental organisations calls for a 2025 ban on oil and gas venting and flaring in the UK to reduce methane emissions and improve energy security.

The U.S. aims to reduce greenhouse gas emissions by 50-52% below 2005 levels by 2030. While the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) provide significant reductions, a gap of approximately 810 million tonnes CO2e remains. The Clean Air Task Force (CATF) proposes a 'high impact' scenario leveraging Clean Air Act regulatory authority and agriculture/forestry spending to close this gap.

The U.S. Department of Energy (DOE) is funding between four and ten Regional Clean Hydrogen Hubs (H2Hubs) using $8 billion allocated by the 2021 Infrastructure Investment and Jobs Act (IIJA). These hubs are designed to catalyze domestic clean hydrogen production and operationalize the DOE's Hydrogen Shot goal of reducing production costs by 80% to $1 per kilogram within ten years. Applicants are evaluated on feedstock diversity (requiring demonstrations from fossil fuels, renewable energy, and nuclear energy), end-use diversity (covering electric power, industrial, residential/commercial heating, and transportation), a minimum 50% non-federal cost share, and community benefits plans aligned with the Justice40 Initiative. The program aims to decarbonize hard-to-electrify sectors—which accounted for nearly 16% of U.S. emissions in 2018—and foster hydrogen-fueled transportation corridors and export potential. Financial viability is further supported by the Inflation Reduction Act's Section 45V tax credit, offering up to $3.00 per kilogram of clean hydrogen for projects starting construction before 2033.
