The report refutes the claim that fossil gas alternatives (FGAs) can decarbonize buildings, asserting that their limited supply and high costs make them an inefficient choice compared to electrification. It highlights that FGAs can only replace a small fraction of gas demand and may exacerbate pollution and health risks. The document further alleges that the gas industry uses FGAs as a rhetorical tool and employs 'front groups' to stall the transition to all-electric buildings to protect its financial interests.

The report addresses the vulnerability of energy infrastructure in Small Island Developing States (SIDS) to extreme weather, arguing that while solar PV is a cost-effective alternative to imported fossil fuels, it requires specific engineering and policy standards to survive Category 5 hurricanes. Based on field analyses of failures from 2017–2019, the authors recommend moving away from shared top-down clips toward through-bolting and dual post piers for ground systems, and prohibiting ballasted-only rooftop systems. Implementing these resilience measures is estimated to increase engineering, procurement, and construction (EPC) costs by approximately 5%, a cost offset by avoiding total system rebuilds. The report emphasizes multi-stakeholder collaboration and the integration of high-wind standards into local building codes to ensure long-term energy security.

The briefing examines how advancements in battery longevity, specifically reducing degradation and increasing cycle life, can unlock new economic opportunities and technical capabilities. It highlights that while energy density and price are common focuses, cycle life is the primary barrier to the widespread adoption of fast charging, vehicle-to-grid (V2G) integration, and the use of second-life batteries for long-duration grid storage. The author suggests that standardized chemistries and better monitoring are necessary to build a viable second-life battery ecosystem.

The Clean Air Task Force (CATF) supports the European Commission's goal of at least 55% emissions reductions by 2030 and argues that achieving carbon neutrality by mid-century requires a diverse portfolio of advanced technologies beyond wind and solar. CATF recommends optimizing the EU ETS to fund commercial-scale demonstrations of carbon capture and hydrogen, implementing mandatory leak detection and repair for oil and gas systems, and using the EU's purchasing power to pressure major gas suppliers like Russia and Qatar to reduce methane emissions.

The programme aims to install 7.8MW of solar capacity, consisting of 6MW of on-grid rooftop solar and 1.8MW of off-grid solar micro-grids. It seeks to transition remote island barangays from diesel-based power to renewable energy through a model involving Land Bank of the Philippines, AIEC-ILAW, and One Renewable Energy Enterprise, Inc. The project includes technical assistance for policy development, financing for infrastructure, and capacity building for electric cooperatives (ECs).

The report finds that Eskom's Kendal Power Station recorded 2,851 exceedances of its 100 mg/Nm3 particulate matter (PM) limit between April 2016 and March 2020. Exceedances increased significantly in April 2018 and remained high, with January 2020 recording the highest monthly total of 151. The analysis indicates that existing electrostatic precipitators are failing, and the author recommends either shutting down the plant or rapidly retrofitting all six units with fabric filters to meet AEL and World Bank standards.

The report examines the increasing need for energy resilience in the Upper Roaring Fork Valley, Colorado, following the 2018 Lake Christine Fire. It argues that traditional grid hardening and backup generators are insufficient and proposes a shift toward distributed energy resources (DERs) and community-centric planning. Through a partnership between Holy Cross Energy (HCE) and local stakeholders, the report identifies five priority resilience areas: community microgrids, bulk power supply flexibility, mobile generation fleets, gasoline pump resilience, and critical end-use efficiency. It emphasizes the need for 'blue sky' value—benefits during normal operations—to justify the cost of 'black sky' emergency investments and recommends new business models, such as split ownership and updated tariffs, to facilitate the deployment of clean energy resilience solutions.

The document advocates for the integration of advanced nuclear energy into a diversified zero-carbon energy portfolio to mitigate the risks and costs associated with relying solely on variable renewables. It highlights nuclear's advantages in power density, dispatchability, and its ability to produce carbon-free hydrogen for hard-to-electrify sectors. While acknowledging challenges such as high costs, waste disposal, and public perception, the author suggests that standardized construction, advanced reactor designs, and supportive federal policies—specifically the Nuclear Energy Leadership Act (NELA)—can make nuclear a scalable and cost-effective tool for climate mitigation.

The NewClimate Institute proposes a virtual Article 6 pilot in Khovd, Mongolia, to replace coal-based district heating with ground source heat pumps (GSHP). The project aims to reduce GHG emissions and air pollution while testing the application of Article 6 carbon market mechanisms, arguing that the project is additional due to high upfront costs and low local technological maturity.

The document examines a 2020 Swedish government inquiry into sewage sludge management, which weighed a complete ban on agricultural reuse against continued use under stricter quality requirements. While the inquiry focused on recovering phosphorus, the authors argue that this narrow focus ignores the significant potential for recovering nitrogen and potassium, which could reduce Sweden's dependence on imported fertilizers and lower greenhouse gas emissions. The brief highlights the role of the REVAQ certification programme in controlling contaminants and discusses alternatives such as incineration with ash-based phosphorus recovery and source-separation of blackwater and urine.

The document examines the potential of 'flexible demand'—shifting the timing of electricity use—to support a clean energy transition. It contrasts this with traditional demand response, highlighting how advanced metering and smart technology can align consumption with renewable energy production, reduce the need for natural gas 'ramp' plants, and avoid costly infrastructure upgrades. The author identifies key flexible end uses, such as electric vehicle charging and space heating, and proposes three mobilization models: behavioral, price-exposed, and subscription-enrolled. It concludes with recommendations for regulators to align utility incentives and ensure equitable program design.

The report outlines a comprehensive strategy for the United States to achieve carbon neutrality by 2050 through a diversified portfolio of carbon removal pathways. It categorizes these into 'Staples' (tree restoration and direct air capture), 'No Regrets' (agricultural soil carbon management), 'Speculative Bets' (carbon mineralization and enhanced root crops), and 'Supplemental Pathways' (BECCS, wood waste preservation, and extended timber rotations). The authors argue that an 'all-of-the-above' approach is the most robust and cost-effective, potentially removing 20 GtCO2 cumulatively by 2050. Key recommendations include federal subsidies for tree restoration, an expanded 45Q tax credit for direct air capture, and a 10-million-acre farm innovation program. The report also emphasizes the need for a 'strong enabling environment,' including low-carbon energy, credible life-cycle assessments, and improved geological storage and monitoring infrastructure.

The report advocates for a paradigm shift in sanitation and wastewater management, moving from a focus on waste disposal to one of resource recovery. It details how recovering water, nutrients, and energy from waste streams can improve public health, food security, and climate mitigation while creating economic opportunities. The document provides technical guidance on system design, risk management for human and environmental health, and the institutional and financial frameworks necessary to implement sustainable, context-specific sanitation systems.

The report describes the implementation of a groundwater monitoring network in Newlands and the Epping/Airport Industria areas of Cape Town. It combines desktop research from databases like WARMS and the National Groundwater Archive with field-based 'groundtruthing' via hydrocensus surveys of private borehole owners. The project identifies the geological characteristics of the Table Mountain Group and Cape Flats aquifers and deploys Solinst Leveloggers to track water levels. The findings highlight a significant increase in private borehole drilling between 2015 and 2019 and note concerns among users regarding water quality and the sustainability of abstraction levels.

The document advocates for a transition to cleaner transportation fuels in the US Midwest, highlighting the region's leadership in biofuels and wind energy.

The report examines the technical and economic feasibility of electrifying heavy-duty vehicles (HDVs) in the US, highlighting their potential to significantly reduce NOx, PM2.5, and greenhouse gas emissions. It argues that current battery technology is sufficient for the majority of HDV operating ranges and that total cost of ownership is becoming competitive with diesel. The document recommends a combination of financial incentives, infrastructure investment, and regulatory standards to drive the transition.

The document is a GCF Readiness proposal for Thailand, implemented by the UN Environment Programme's Climate Technology Centre and Network (CTCN). It aims to address barriers to the adoption of the 2009 Building Energy Code (BEC) by providing techno-economic recommendations and capacity building. The project focuses on five building types (offices, hotels, department stores, medical centers, and condominiums) over 2,000 m2. Key planned activities include establishing energy and GHG baselines, conducting financial and technical assessments of available technologies, performing energy audits on existing buildings for retrofitting, and developing a Measurement, Report and Verification (MRV) framework. The project also includes the creation of three handbooks for local authorities, practitioners, and investors to enhance the enforcement and implementation of BEC standards.

The report details IISD's Bioeconomy project (2017-2019) focusing on harvesting unconventional biomass from water retention sites and roadside ditches in Manitoba. It argues that this practice removes phosphorus to protect Lake Winnipeg, improves habitat health, and provides a low-carbon alternative to fossil fuels or a means of soil carbon sequestration. The document analyzes harvesting methods, the shift from bioenergy to livestock bedding and compost, and evaluates global and North American carbon market verification methodologies to identify frameworks suitable for these watershed management activities.

The Espejo de Tarapacá project in Chile proposes the construction of a 300 MW pumped storage hydroelectric (PSH) plant and a 561 MW-AC photovoltaic (PV) solar plant. The project aims to provide a renewable baseload energy solution to the Chilean national grid, reducing CO2 emissions by an average of 1,001,187 tonnes per year. The proposal requests US$ 60 million in direct equity from the Green Climate Fund (GCF) to act as an 'anchor' investor, helping to overcome market barriers and attract an additional US$ 1 billion in private sector debt and equity. Beyond energy generation, the project includes adaptation measures for local fishing communities in the Tarapacá Region, such as providing stable drinking water via a desalination plant and funding for economic diversification.

The briefing contends that the Yucca Mountain repository is 'irrevocably flawed' due to geological instability, including earthquake and volcano risks, and a failure to meet groundwater travel time standards. It highlights that the 2008 license application is obsolete because the Department of Energy abandoned the specific waste package design it was based on. The document further notes that the site's safety relies on unproven 'titanium drip shields' estimated to cost $5 to $9 billion (2018 dollars). It concludes that reviving the project would require billions in funding for licensing and infrastructure, such as a 300-plus mile rail line, and instead advocates for a 'consent-based' approach to nuclear waste management.
