The document outlines Mexico's waste sector methane emissions, the existing institutional and legal framework for waste management, and the challenges and opportunities for achieving GHG mitigation targets.

The report evaluates the technical feasibility of drilling superhot rock (SHR) geothermal wells—defined as depths >5 km and temperatures >374°C. It concludes that while the necessary technologies exist or are emerging, significant gaps remain in rate of penetration (ROP) for hard rock, high-temperature electronic tool durability, and temperature management. The analysis categorizes rock-destroying equipment into conventional rotary, hybrid, and direct energy methods, assigning Technology Readiness Levels (TRL) to each. It emphasizes that the primary barrier to progress is a lack of access to SHR conditions in both laboratory and field settings, which prevents the iterative testing needed to reduce costs and risks.

The Infrastructure Investment and Jobs Act (IIJA) allocated $12.1 billion to advance carbon management technologies in the United States. Two years into implementation, the Department of Energy (DOE) and Environmental Protection Agency (EPA) have launched several key programs. The Carbon Capture Demonstration Projects Program has selected nine FEED study projects and three demonstration projects, including the Baytown, Project Tundra, and Sutter projects. The Carbon Storage Validation and Testing Program has awarded funding to projects across multiple states, including Texas, Louisiana, and Wyoming, to develop large-scale sequestration and transport infrastructure. Additionally, the EPA has allotted $48 million to 25 state and Tribal recipients to support the regulation of UIC Class VI wells. In the realm of carbon removal, the Regional Direct Air Capture (DAC) Hubs Program has selected two commercial-scale hubs in Texas and Louisiana for award negotiations. The document notes that while progress is underway, agencies have until 2026 to allocate remaining funds, and future success depends on shared transport networks and community engagement.

The study investigates the transition of Poland's power system to a 99% reduction in emissions by 2050. The 'base' scenario identifies onshore wind as the dominant generation source, complemented by nuclear power, gas plants with carbon capture and storage (CCS), and hydrogen storage. The analysis emphasizes that a technology-inclusive approach is essential for competitiveness, as scenarios excluding nuclear and CCS result in significantly higher electricity prices and system costs. Key recommendations include maximizing onshore wind deployment, advancing a nuclear fleet exceeding 8 GW, and establishing CO2 transport and storage infrastructure by 2035.

The Clean Air Task Force (CATF) proposes a five-category framework—critical analysis, regulatory programs, financial incentives, economic and community benefits, and leveraging additional funding—to guide states in applying for the $4.6 billion in CPRG implementation funding. Using the medium- and heavy-duty vehicle (MHDV) sector as an example, the guide details how states can use these funds for activities such as grid congestion studies, adopting the Advanced Clean Trucks rule, providing charging station subsidies, and establishing workforce training programs with community colleges.

The Clean Air Task Force (CATF) advocates for the adoption of three specific accounting standards—new supply, hourly matching, and deliverability—for the Section 45V Clean Hydrogen Production Tax Credit. CATF warns that without these 'Three Pillars,' electrolytic hydrogen could result in consequential emissions twice as high as conventional 'gray' hydrogen by diverting clean power from the grid and forcing a reliance on fossil fuel generation. While the organization suggests these strict standards are essential for long-term deployment funding under 45V and EPA rules, it notes they may be less critical for short-term demonstration programs like the Regional Clean Hydrogen Hubs Program.

The methodology involves isolating specific federal agency lands in the contiguous US, intersecting these areas with resource suitability data from the Princeton Net Zero America Study and the Global Heat Flow Database, and applying conservative and optimistic capacity density estimates to calculate total gigawatt (GW) hosting capacity across four scenarios.

The report analyzes the impact of amine-based carbon capture retrofits at two petroleum refineries and two cement plants in California and Texas. It finds that because carbon capture systems require the removal of pollutants like sulfur dioxide and particulate matter from flue gas to operate effectively, their installation leads to significant reductions in criteria air pollutants and associated public health improvements. While the systems cause a small increase in volatile organic compounds (VOCs), the combined climate and health benefits are estimated to be 1.5 to 4 times greater than the costs of the technology.

The report argues that nuclear energy is essential for a reliable, zero-carbon energy system but has stagnated since 1990 due to high costs and slow delivery. It proposes a 'fundamental reset' of the industry, shifting from bespoke mega-projects to standardized, manufactured products. Key recommendations include the creation of Independent Nuclear Development Organizations (INDOs) to integrate project delivery, a Global Licensing Authority (GLA) to harmonize international regulations, an International Technical Support Organization (ITSO) to assist embarking nuclear nations, and an International Bank of Nuclear Infrastructure (IBNI) to expand financing access. CATF analysis suggests these combined measures could reduce overnight construction costs by as much as 60% from first-of-a-kind to Nth-of-a-kind reactors.

The report identifies a critical gap in the energy policy lifecycle, which it terms the "policy valley of death," where a lack of effective planning prevents financial incentives from achieving emissions targets. It argues that waiting for a decarbonized system to self-assemble through individual projects is inefficient and fails to address the scale of mid-century needs. To resolve this, the authors propose five principles for effective energy planning: being proactive and risk-aware, adopting a multi-jurisdictional and systems-perspective, co-creating plans with all stakeholders, utilizing comprehensive scenario-based analysis, and establishing actionable roadmaps with accountable progress tracking. The document further details five essential components for a durable plan: a stakeholder engagement roadmap, proactive risk-aware analysis, an implementation roadmap, progress tracking mechanisms, and knowledge-sharing centers.

The briefing analyzes the failure of the NuScale-UAMPS Carbon Free Power Project, attributing its cancellation to the inherent risks of first-of-a-kind (FOAK) projects, a lack of modularity in the VOYAGR design, and the selection of a customer (UAMPS) ill-equipped for nuclear risk. Despite the project's end, the author notes that NuScale achieved significant regulatory milestones, including the first SMR design certification and reductions in staffing and security requirements. The document argues that FOAK SMRs should be treated as demonstrations rather than commercial endeavors, suggesting that governments provide streamlined prototype sites and cost-overrun insurance, while targeting non-utility customers like data centers and heavy industry who have a higher demand for 24/7 carbon-free power.

The paper argues that low-carbon hydrogen should be reserved for 'no-regrets' industrial applications—such as refining, ammonia, methanol, and steel production—rather than residential heating or light-duty vehicles, due to high energy costs and physical transport challenges.

The policy brief advocates for a transition to 24/7 carbon-free energy (CFE) in Europe, asserting that variable renewable energy alone cannot maintain grid reliability. It proposes a three-pronged approach: commercialising 'clean firm' technologies (such as next-generation nuclear, CCS, and geothermal), reforming electricity market designs to move beyond short-term marginal cost pricing toward hybrid markets that reward capacity, and updating the GHG Protocol's Scope 2 accounting from annual to hourly tracking to incentivise the procurement of dispatchable carbon-free power.

The EPA has launched Phase 2 of the Climate Pollution Reduction Grants (CPRG) program, offering $4.3 billion in a general competition and $300 million for tribes and territories to implement Priority Climate Action Plans (PCAP). Eligible projects must focus on greenhouse gas (GHG) reduction across sectors such as electric power, transportation, and industry, with a strict application deadline of April 1, 2024. The document advises states and municipalities to proactively coordinate and engage underserved communities to maximize funding opportunities within the tight timeframe.

The document argues that achieving a just, decarbonized economy requires a cooperative, cross-sectorial approach to climate action that engages disenfranchised and underserved communities. It asserts that the most critical issues for these populations are those impacting health, economic wellbeing, and overall prosperity, resulting from compounding inequities and multifaceted environmental risks.

The Clean Air Task Force (CATF) argues that low-carbon hydrogen is essential for decarbonizing hard-to-electrify sectors like heavy industry and long-haul transport. In Pennsylvania, the MACH2 and ARCH2 hubs represent diverse production strategies—renewable/nuclear and natural gas reforming, respectively. CATF emphasizes that for hydrogen to be truly climate-beneficial, electrolytic production must follow 'three pillars' of additionality, geography-matching, and temporal-matching, while fossil-based production requires high carbon capture rates and minimized methane leaks. The document highlights Pennsylvania's significant geologic storage potential for carbon capture but notes a lack of public subsurface data. It recommends greater transparency, inter-hub coordination, and deeper community engagement to maximize the program's climate and social benefits.

The document argues that current GHG Protocol Scope 2 rules are insufficient for impactful decision-making due to a lack of temporal and geographic granularity. The signatories propose a three-part framework for modernization: updating the Location-Based Method with more granular data, improving the Market-Based Method through stricter time- and location-matching requirements to align with physical electricity deliverability, and introducing new, separate consequential impact disclosures to reflect the actual atmospheric emissions resulting from a buyer's actions.

The report details a survey of 6,021 respondents across Germany, Italy, Poland, Romania, Spain, and the UK regarding clean energy technologies. Key findings indicate that while advanced nuclear energy has the highest awareness and broad support, superhot rock geothermal energy has the lowest awareness. Support for CCS and SHR is influenced by how the technologies are framed, and while low-carbon hydrogen is generally supported, there is uncertainty regarding its application sectors.

The report examines Community Benefits Agreements (CBAs) as legally binding contracts between developers and communities to ensure equitable outcomes in energy transitions. Through nine case studies and an analysis of DOE, DOT, and EPA guidelines, it identifies critical failure points—such as lack of representative stakeholders and poor enforceability—and proposes best practices for planning, negotiation, and monitoring to better align project development with community needs.

The report examines the DOE's Community Benefits Plan (CBP) process, which requires grant applicants to commit to equitable community and workforce strategies. While the CBP is credited with forcing developers to prioritize equity and job quality, the report identifies significant challenges, including limited DOE capacity, rushed timelines, and growing stakeholder fatigue. Community surveys reveal deep skepticism due to unfulfilled past promises and a preference for environmental quality improvements over clean energy funding. The report recommends that the DOE improve accountability, provide seed funding for commitments, and leverage other federal agencies to support under-resourced community groups.
