The Clean Air Task Force (CATF) recommends a cautious, safeguard-driven integration of permanent carbon removals (specifically DACCS and BioCCS) into the EU ETS to avoid deterring direct emissions reductions. The briefing argues for expanding the ETS scope to include extra-EEA flights, vessels above 400 gross tonnage, and municipal waste incineration and landfills. It specifically highlights the need to address non-CO2 aviation impacts, such as contrails, through financial incentives and robust monitoring. To support the transition, CATF suggests earmarking aviation ETS revenues for sustainable aviation fuels (SAF) and maintaining SAF allowances beyond 2030.

The report argues that traditional conservative utility planning, which bases connection decisions on worst-case load scenarios, creates lengthy delays for electric truck charging sites. Flexible service connections (FSCs) offer an alternative where customers agree to limit charging during peak hours to ensure grid safety, reducing energization timelines from years to months. RMI's analysis of Pacific Gas & Electric (PG&E) and National Grid data shows that FSCs are most effective on feeders with sharp, narrow late-afternoon peaks, typically near large population centers. In PG&E territory, just four hours of load shifting could theoretically support more medium- and heavy-duty electric vehicles than have been sold to date in California. The report highlights the role of managed charging and on-site battery storage in making FSCs operationally viable for fleets and calls for regulators to standardize these offerings.

The report details the economic importance of Paraguay's livestock sector, which contributes approximately 12% of the national GDP, while highlighting its role as a major emitter of methane. It identifies a significant gap in productivity, noting that 85% of producers are small-scale and only 22% use improved genetics with technical assistance. The document argues that increasing efficiency—through genetic improvement, reproductive technologies, and regenerative pasture management—can simultaneously reduce emission intensity and increase profitability. It references Paraguay's NDC 3.0 goal to reduce emissions by 20% by 2030, with a specific target of mitigating 2,570.3 kt CO2eq through Good Livestock Production Practices. The report concludes with recommendations for a multi-sectoral roadmap, the development of green financial products like Brazil's Eco-Invest, and the creation of a permanent inter-institutional working group to monitor climate goals.

The briefing examines the grid constraints facing electric truck charging depots, which often require 5–10 MW per site and have shorter development timelines than traditional large loads. It proposes 'flexible service connections'—agreements where utilities provide higher power capacity during off-peak periods in exchange for managed consumption—as a solution to avoid costly and slow infrastructure upgrades. RMI analysis indicates that many fleets in California and New York can shift charging to overnight or solar-peak hours without altering operations, potentially reducing capital costs by 40% to 70%. The document highlights pilots by National Grid, Southern California Edison, and PG&E, noting that PG&E's Flex Connect program enabled PepsiCo to expand its electric fleet 18 months faster than conventional planning, saving an estimated $1 million in fuel costs.

India's coal fleet is shifting from baseload to flexible balancing to integrate rising solar and wind energy. By FY 2031–32, coal plants will need to operate closer to their technical minimums, with a projected average plant load factor (PLF) drop from 69% to 55%. This transition will disproportionately impact high-cost, less efficient units, suggesting that the 35 GW of coal capacity currently under construction is sufficient for supply security without further additions.

The report examines the energy demands of data centres in ASEAN, particularly those driven by AI, and argues that a dual approach of increasing solar and wind power procurement and enhancing energy efficiency is essential. It highlights that current grid emission targets in key hubs are insufficient and suggests that at least 30% of electricity demand in five ASEAN data centre hubs could be met by wind and solar by 2030 without immediate battery storage. The document emphasizes the critical role of cooling systems in tropical climates and the potential for software optimisation to reduce energy consumption.

The briefing examines the components of grid reliability—resource adequacy, operational reliability, and resilience—within the context of the U.S. transition to clean energy. It argues that while load growth and fossil fuel retirements create short-term risks, a diverse portfolio of wind, solar, batteries, and demand-side resources can maintain reliability. The document emphasizes the need for interconnection reform, updated market rules for inverter-based resources, and the scaling of demand-response programs to avoid unnecessary supply-side costs.

The report analyzes the environmental impact of the global data-center boom, identifying systemic challenges such as energy infrastructure lags and temporal-spatial mismatches between green power and demand. It proposes a comprehensive transformation pathway involving optimized site selection, enhanced energy efficiency through new metrics beyond PUE, and the adoption of diverse green power procurement options. The document emphasizes the potential for data centers to act as flexible grid resources and calls for mandatory carbon disclosure and standardized accounting to drive the transition.

ASEAN's electricity demand grew by 3.6% in 2023, a rise entirely met by fossil fuels, leading to a 6.6% increase in power sector emissions. While solar and wind costs are falling, the region remains heavily dependent on coal and gas, and hydropower has become less reliable due to climate-induced droughts. The report argues that scaling renewable capacity by 3-5x by 2035, implementing direct power purchase agreements, and expanding the ASEAN Power Grid are essential to meet rising demand and climate goals. It also highlights the potential for a regional compliance carbon market and the importance of a just transition to secure social acceptance.

The briefing advocates for a coordinated approach to building decarbonization and resilience in the US, emphasizing that these goals are complementary. It specifically prioritizes 'passive measures'—such as weatherization and envelope retrofits—to manage peak electricity demand, improve energy affordability, and extend the 'hours of safety' for occupants during power outages, particularly for vulnerable populations.

The document contends that the U.S. power grid is already transitioning away from coal toward renewables, storage, and flexible natural gas due to market forces, and that the EPA's Rule aligns with these trends. It argues that modern resources like battery storage and flexible gas plants provide better operational reliability than aging coal plants. The brief asserts that the Rule provides sufficient time for resource procurement and includes flexibility mechanisms to protect the grid during periods of stress.

The enee.io energy monitoring system identified that a 48V VRLA battery bank in Lagos, Nigeria, was being overcharged, reaching a maximum of 2.35vpc (56.4v) and remaining there indefinitely. This overcharging caused energy loss of 6.2kWh per day and reduced the estimated battery life from 4.0 years to 2.1 years. By adjusting voltage regulation and implementing ongoing monitoring, the system estimates total daily savings of $7.12, consisting of $4.64 from extended battery life and $2.48 from reduced diesel consumption. The enee.io system, costing $340 USD for hardware and the first year's subscription, offers a projected return on investment of 48 days.

The document argues that Section 45Z should prioritize low-carbon aviation fuels and avoid over-subsidizing biofuels with high indirect emissions. It recommends modifying the GREET model to align with CORSIA standards for indirect land use change (ILUC) and cautions against using negative emissions values or fugitive methane from oil and gas as feedstocks. Additionally, it advocates for the eligibility of synthetic sustainable aviation fuel (SAF) and the independent application of tax credits across the fuel value chain.

The report examines how grid-enhancing technologies (GETs) can address interconnection bottlenecks in the PJM region, potentially enabling 6.6 GW of new solar, wind, and storage projects by 2027 and providing approximately $1 billion in annual production cost savings.

The report argues that empowering consumers to manage their energy demand and production can shift approximately 900 TWh—about 27% of global residential electricity consumption—away from fossil fuels. It categorizes empowerment solutions into supply-side (e.g., 24/7 PPAs, energy cooperatives, P2P trading), demand-side (e.g., time-of-use tariffs, on-bill schemes), and data-based (e.g., smart meters, granular energy certificates) interventions. The document emphasizes that the path to 24/7 CFE varies by country maturity, dividing nations into 'Potential', 'Progressive', 'Aspirer', and 'Frontier' archetypes, each requiring different policy 'recipes' to overcome barriers such as low smart meter penetration and restrictive electricity market regulations.

Ember argues that new coal facilities entering the Safeguard Mechanism should be held to a net zero emissions intensity baseline to align with 1.5 degree climate pathways. While supporting the proposed production variable of 0.0653 CO2-e per tonne of run-of-mine coal for driving reductions in high-intensity underground mines, Ember warns that open-cut mines may receive windfall Safeguard Mechanism Credits (SMCs) without performing genuine abatement due to outdated emissions reporting factors.

The report argues that scaling green hydrogen for a 1.5°C-aligned future will not severely impact global freshwater supplies, as its water consumption is comparable to or lower than fossil-fuel-based hydrogen and other energy production methods. It estimates that meeting 2050 hydrogen demand targets would require only 0.33% of current global freshwater. To mitigate local water stress, the document recommends using non-freshwater sources like desalinated seawater or treated wastewater, intentional project siting, and revising water pricing structures to incentivize efficiency.

Carbon Market Watch argues that current carbon market mechanisms, such as buffer pools and insurance, are insufficient to guarantee the multi-century permanence required for carbon removals to credibly offset ongoing emissions. The organization recommends extending project proponent monitoring responsibilities to at least 100 years, implementing strict reversal notification timelines (within 30 days), and requiring the automatic cancellation of unused buffer credits. To address equity concerns, it suggests that liability for reversals should shift to acquiring Parties or be funded via top-off fees and a Secretariat-managed satellite monitoring system, rather than falling on host Parties, many of which are developing nations.

The document explains that many metals critical for the energy transition and digital transformation are not extracted exclusively but as co-products or by-products of 'host' metals. This complementarity creates inelastic supply chains, high price volatility, and risks of material loss in tailings. It suggests that understanding these associations can help governments and companies identify new sources of minerals, such as reprocessing tailings, and improve national industrial strategies.

The document examines how selecting materials with low embodied carbon or carbon-storing properties during building retrofits can prevent emissions spikes and transform buildings into carbon sinks. It analyzes exterior insulation systems and affordable multifamily housing projects in the Northeast to demonstrate that sustainable material substitutes are currently available to help meet 2030 decarbonization goals.
