The document argues that carbon capture and storage (CCS) is essential for Europe to reach net-zero emissions by 2050, particularly for hard-to-abate industrial sectors like cement and steel. It details the technical processes of capture and geological storage, asserts that leakage risks are extremely low, and outlines current project developments in the North Sea region and across the EU. The text also addresses the economic viability of CCS, noting that while costs vary by industry, the technology is often the lowest-cost path for specific industrial decarbonisation and carbon dioxide removal (CDR).

A coalition of NGOs and research institutions advises the U.S. Department of Energy to implement a comprehensive transparency model for the Regional Clean Hydrogen Hubs Program. The recommendations focus on four key areas: enabling community engagement through the release of project sites and benefit plans; building program credibility by sharing selection hypotheses and funding details; evaluating long-term impacts via public reporting of climate and environmental data; and fostering market development by sharing technical specifications and lessons learned from both successful and failed projects.

The document argues that large-scale deployment of CCS is essential for Europe to reach climate neutrality by 2050, yet current draft NECPs show significant gaps in targets and planning. It provides a framework for Member States to assess storage capacity, map projects, engage stakeholders, and establish financing and regional cooperation for CO2 transport and storage networks.

The document argues that clean hydrogen should be treated as a 'precious molecule' and prioritised for 'no regrets' hard-to-abate industrial sectors rather than being deployed indiscriminately. It recommends that EU Member States move beyond a sole focus on renewable ('green') hydrogen to include other low-carbon pathways, such as nuclear ('pink') and natural gas with carbon capture ('blue'), to avoid resource constraints. The guide emphasises locating production close to end-users to minimise transport inefficiencies and suggests that hydrogen in transport be limited to heavy-duty trucking, aviation, and shipping, while light-duty vehicles should prioritise electrification. Finally, it advises leveraging EU and national support mechanisms to fund 'champion' projects across the entire value chain.

The document argues that superhot rock (SHR) energy—a subset of Engineered Geothermal Systems that accesses rock temperatures exceeding 400°C—could provide a zero-carbon, firm, and energy-dense power source available globally. It notes a significant gap in current EU planning, where only one country (Italy) mentions SHR in its draft NECP, despite 20 countries planning for geothermal energy. The guide recommends that Member States fund pilot demonstrations, map national SHR resources, contribute to a centralised EU geothermal data repository, develop national geothermal strategies, and create stakeholder collaboration platforms. It highlights that SHR systems can potentially produce up to ten times the energy of conventional geothermal wells and could support the production of clean hydrogen.

The document argues that SMRs can provide 'clean firm' power to decarbonize industrial systems and bolster energy security in the EU. It identifies that while 12 countries mention SMRs in draft NECPs and 7 plan investments, significant work is needed to improve these plans. The guide outlines five key recommendation areas: developing planning competencies (including techno-economic assessments and workforce studies), strengthening regional cooperation (such as joint licensing and a Joint Procurement Platform), enhancing financial frameworks (using contracts for difference and state aid), establishing national R&D and demonstration programmes, and creating industry-informed roadmaps. It specifically highlights the need for regulators to diversify competence beyond Light Water Reactors to evaluate advanced technologies like molten salt reactors.

The Clean Air Task Force (CATF) advocates for the EPA to promptly finalize comprehensive emissions standards for coal and both new and existing gas power plants. CATF argues that these regulations are compatible with electric grid reliability due to built-in flexibilities and compliance timelines. The organization emphasizes that timely action is necessary to align with federal investments from the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, and to help the U.S. meet its Nationally Determined Contribution of a 50 to 52% reduction in carbon pollution below 2005 levels by 2030.

The Clean Air Task Force (CATF) urges the EPA to finalize Phase 3 regulations for heavy-duty vehicles (HDVs) covering model years 2027-2032. The document highlights that HDVs contribute 59% of ozone- and particle-forming NOx emissions and 55% of particle pollution in the US, leading to significant health damages and deaths. It asserts that the industry is already transitioning toward zero-emission vehicles (ZEVs), citing new battery-electric and fuel cell electric vehicle (FCEV) models from manufacturers like Mercedes, Nikola, and Tesla. Furthermore, the document details extensive federal funding from the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA) intended to build out charging and hydrogen refueling infrastructure, arguing that these resources make strong regulatory standards feasible and necessary.

The marine shipping industry, responsible for about 3% of global GHG emissions, is under pressure to decarbonize following new targets from the EU and the IMO. The Clean Air Task Force (CATF) highlights that dual-fuel engines, which can run on conventional fuel as well as alternatives like methanol and ammonia, are becoming a standard design to provide flexibility over a ship's 30-plus-year lifespan. CATF's analysis indicates that ammonia-fueled ships could nearly fully decarbonize at a lower lifetime fuel cost than heavy fuel oil if carbon pricing is in place. To achieve these goals, the document recommends a clean marine fuel standard that mandates minimal upstream emissions, ensures safe bunkering, requires on-board pollution controls for gases like nitrous oxide, and uses economic incentives like a low carbon fuel standard to manage the higher costs of zero-emission fuels.

The report argues that CCS is essential for the EU to reach climate neutrality by 2050, noting that current deployment rates are far below required levels and that no operational CO2 storage sites currently exist within the EU. It recommends setting clear deployment targets for CCS, DACCS, and BECCS, and establishing a strategic plan to distribute storage basins across the region by 2035 to avoid over-reliance on the North Sea. To address financial barriers, the author suggests coordinating funding, using carbon contracts for difference (CfDs), and creating a dedicated tender for capture capacity. The report also emphasizes the need for a common regulatory framework for cross-border CO2 transport, the creation of an aggregation platform to match CO2 sources with sinks, and the development of market demand for near-zero carbon products. Finally, it advocates for the prioritization of permanent industrial carbon removals (DACCS and BECCS) and their gradual integration into compliance markets like the EU ETS, provided robust standards and monitoring are in place.

The report analyzes how the energy and transportation sectors drive air pollution in the U.S., noting that while the Clean Air Act has significantly reduced overall emissions since 1970, severe exposure disparities persist. It highlights that people of color and low-income populations are more likely to live in areas exceeding health standards, often near 'pollution hot spots' that current monitoring networks may miss. Through case studies in California, New Jersey, and Indiana, the document illustrates the specific health burdens—including asthma and cancer—borne by marginalized communities living near ports, incinerators, and coal plants.

The analysis demonstrates that ships built or retrofitted with dual-fuel capacity for ammonia can meet or exceed EU marine sector decarbonization targets at costs equal to or lower than conventional heavy fuel oil (HFO) ships when carbon pricing is applied. A new build fully powered by ammonia can reduce lifetime emissions by 77% with a lifetime fuel cost equivalent to an HFO ship, while retrofits can reduce emissions by 41-52% at a lower overall cost. The report highlights that ammonia's viability depends on the availability of varying carbon intensities—from 'moderate CI' produced via natural gas with carbon capture to 'very low CI' produced via electrolysis—and notes that while ammonia is already handled globally, its toxicity requires purpose-built ship systems and ongoing safety validation by the IMO.

The report identifies a shift in clean energy deployment challenges from technical and economic issues to social and institutional barriers, specifically community resistance to wind and solar projects. Based on workshops with 25 practitioners and researchers, it proposes four paradigm-shifting solutions: a 'fair share' policy to distribute infrastructure burdens across a state, 'off-the-shelf' visioning modules to help communities self-determine their desires before projects are proposed, the creation of local task forces supported by trusted facilitators to build capacity, and the development of co-ownership or co-management models to increase local benefits and acceptance. The document also highlights unresolved tensions, such as the conflict between the urgent need for rapid decarbonization and the time required to build meaningful community trust.

The 2024 Toll from Coal analysis uses the U.S. EPA's COBRA v5.2 model to link emissions of PM2.5, SO2, NOx, and VOC from coal-fired power plants to health outcomes and economic damages across the continental United States. Comparing 2024 data to 2019, the analysis finds that reported NOx and SO2 emissions fell by more than one-third, while direct PM2.5 and VOC emissions decreased by one-quarter. These emission reductions are associated with a decline in all-cause mortality from PM2.5 exposure (from 6,700 to 5,100 deaths) and non-fatal heart attacks (from 2,750 to 1,670). However, ozone exposure was still associated with nearly 1,500 deaths in 2024. Total health damages in 2024 were valued at $100 billion in 2023 dollars.

The document outlines the current state of superhot rock (SHR) geothermal energy, which targets rocks at 400°C or higher to provide scalable baseload power. It identifies a critical need for laboratory and field testing facilities to validate equipment under extreme conditions. The analysis breaks down the technology into five segments: drilling (TRL 2-9), well design and construction (TRL 2-6), heat extraction (TRL 4-8), power production (TRL 5-9), and siting and characterization (TRL 2-9). While many components exist, the document argues that targeted investments in materials R&D, reservoir modeling, and end-to-end system testing are necessary to make SHR cost-competitive with fossil fuels.

Colombia is the third largest methane emitter from the waste sector in Latin America and the Caribbean. In 2018, the waste sector contributed 7% of national greenhouse gas emissions, with 93.4% of those emissions being methane. While the country has a regulatory framework for general waste management, it lacks specific national policies for methane reduction. Key challenges include a tariff system that disincentivizes organic waste diversion and a lack of disaggregated data on waste flows. The document recommends developing a national methane mitigation strategy, revising tariffs to reflect actual capital costs for organic treatment, and improving the technical robustness of municipal Integrated Solid Waste Management Plans (PGIRS).

Colombia is the third largest emitter of waste methane in Latin America and the Caribbean, with the waste sector contributing 22% of national methane emissions. While the country has improved collection and disposal infrastructure, it lacks national policies specifically targeting methane reduction from solid waste. In 2018, the waste sector accounted for 7% of total greenhouse gas emissions, with 52% of those emissions originating from solid waste disposal. Organic waste makes up 70% of the waste stream, yet current tariff systems discourage organic waste diversion by rewarding landfill operators based on waste volume. Key recommendations include developing a national waste methane mitigation strategy, revising tariffs to reflect the costs of organics diversion, and improving data collection on waste flows.

The document explores the role of advanced bioenergy systems in decarbonizing agriculture, emphasizing a 'carbon-negative circular bioeconomy' that combines emissions reductions with permanent carbon dioxide removal (CDR). It identifies opportunities such as utilizing biogenic point sources, growing perennials on underutilized land, and replacing synthetic nitrogen fertilizers. However, it warns of risks including methane leakage from anaerobic digesters, detrimental land-use changes, and environmental justice concerns. The report argues for policy shifts that prioritize CDR over simple energy production and calls for increased research, development, and demonstration (RD&D) to scale cellulosic bioenergy technologies.

New England's energy transition requires a massive shift from fossil fuel reliance to a decarbonized grid, with peak electricity demand projected to double to 55 GW by 2050. The report argues for a 'clean energy portfolio approach' combining solar, offshore wind, energy storage, and interregional transmission to ensure reliability and affordability. It highlights significant sociopolitical barriers, including community opposition and outdated permitting processes, and recommends comprehensive state-level reforms and proactive community engagement to accelerate deployment.

The document outlines Mexico's waste sector emissions, the institutional framework for waste management, and the specific challenges and opportunities for methane mitigation.
