ClientEarth argues that the GBER must be revised to eliminate aid for environmentally harmful activities and prioritise sustainable energy transitions. The organisation recommends integrating the 'do no harm' principle, increasing transparency in state aid reporting, and excluding fossil-fuel-based technologies like high-efficient cogeneration and hydrogen from block exemptions. Conversely, it proposes new aid categories for energy communities, zero-exhaust-emission vehicles, and sustainable battery storage to accelerate the green transition.

The document identifies an "unspoken consensus" among the UK, EU, and US that transitioning to zero-carbon power by the 2030s is essential for reaching net-zero emissions by 2050. It analyzes official pathways, noting a shared commitment to rapidly phasing out coal and reducing fossil gas, while dramatically scaling up wind and solar power. The briefing highlights a "credibility gap" in other OECD nations, such as Japan and South Korea, which have net-zero targets but lack corresponding coal phase-out commitments.

The report finds that the EU is planning a 35% increase in gas import capacity through pipelines and LNG terminals, costing an estimated €87 billion. This expansion is argued to be unnecessary for security of supply and contradictory to the EU's climate goals, creating a significant risk of stranded assets and emissions lock-in. While public financing from the EIB and EU grants has historically catalyzed these projects, the report notes a shift toward phasing out such support, though private finance and initiatives like the Three Seas Initiative continue to pose risks of further fossil gas entrenchment.

The report outlines a strategic framework for zero-carbon investing in China, identifying seven priority technology areas—resource recycling, energy efficiency, demand-side electrification, zero-carbon power generation, energy storage, hydrogen, and digitalization—with a projected market size of nearly ¥15 trillion (US$2.32 trillion) by 2050 and total infrastructure investment of approximately ¥70 trillion (US$10.8 trillion) between 2020 and 2050.

The document outlines eight benefits of building electrification in the United States, asserting it is the only established way to eliminate carbon pollution from residential and commercial heating and cooking. It highlights that all-electric homes are cheaper to build than mixed-fuel homes, improve indoor air quality—particularly for children and marginalized communities—and can create millions of jobs. The text dismisses alternatives like renewable natural gas (RNG), hydrogen, and synthetic methane as too costly or limited in scale, while noting that nearly 60 percent of new US homes are already built all-electric.

The briefing proposes a federal low-carbon product standard for the U.S. cement and steel sectors to drive decarbonization. It suggests setting declining emissions intensity benchmarks and allowing the trading of emissions credits among producers and importers. For cement, the author recommends regulating the cement itself rather than concrete for administrative ease. For steel, the focus is placed on intermediate fabricated products. The document emphasizes that such a standard should include both direct and indirect emissions and be supported by price ceilings and floors to manage credit costs. Implementation via new legislation is preferred over the Clean Air Act to ensure coverage of imports and upstream emissions. Potential abatement technologies highlighted include fuel switching, carbon capture, use and storage (CCUS), energy efficiency, and hydrogen-based steel production.

The Units Conversion Worksheet provides specific multipliers to convert between various units of measurement for five gases: hydrogen, methane, propane, ammonia, and carbon dioxide. It covers conversions for mass (e.g., lb to kg), volume (e.g., kg to Nm3), energy (e.g., kg to GJ-HHV), and cost (e.g., $/kg to $/GJ-HHV). The data is adapted from the NIST Standard Reference Database 23 (DLL 10.0).

The Japanese green bond market grew by a third in 2020, reaching a cumulative issuance of USD 26.15 billion. Issuance is led by financial corporates and government-backed entities, with proceeds primarily allocated to buildings, transport, and energy. The report highlights a strong record of external reviews and post-issuance reporting, while identifying significant opportunities to scale up the market through the refinancing of unlabelled climate-aligned debt, particularly in the transport sector. Additionally, it outlines Japan's policy shift toward net-zero emissions by 2050 and the resulting development of green growth strategies and ESG disclosure frameworks.

ClientEarth argues that the EU is overinvesting in methane gas infrastructure and urges the Commission to implement a methane product standard by 2025 to integrate climate costs into gas prices. The document recommends that public financial support for methane gas or gas-derived hydrogen be precluded or strictly conditioned on carbon capture and storage (CCS) and lifecycle emission caps. It further calls for institutional reform to ensure independent energy system planning, the prioritisation of energy efficiency over new infrastructure, and the cessation of the term 'natural gas' to avoid greenwashing.

The document analyzes Canada's 2020 COVID-19 recovery spending, noting a higher commitment to clean energy (CAD 14.7 billion) than fossil energy (CAD 3.6 billion) according to Energy Policy Tracker data. However, it highlights significant transparency gaps regarding credit support from public finance institutions like EDC and BDC. Compared to France, Germany, and the UK, Canada's per capita investment in electric vehicles is lower, while its investment in building retrofits is relatively high. The brief warns that Canada's hydrogen strategy leans toward 'blue hydrogen' (fossil-based) while European peers prioritize 'green hydrogen'. It recommends applying strict 'green strings' to stimulus, phasing out fossil fuel subsidies, and aligning ambition with international standards.

ClientEarth argues that EU State aid rules must be transformed into sustainability instruments that prohibit support for fossil fuels and harmful biomass, while prioritizing energy efficiency and renewable energy. The document calls for the strict application of the 'Energy Efficiency First' principle, the exclusion of low-carbon (fossil gas-based) hydrogen from subsidies, and the removal of aid for high-efficiency combined heat and power (CHP) plants. It further recommends increasing support for energy communities, zero-emission vehicles, and energy efficiency in buildings, while introducing a 'greenwashing test' to ensure the environmental integrity of aid beneficiaries.

The Virginia Clean Economy Act (VCEA) is projected to nearly eliminate power sector emissions and reduce economy-wide emissions by 35% by 2050 compared to business-as-usual. However, to meet a 1.5°C warming pathway, the document argues that Virginia must implement further policies across transportation, buildings, industry, and land use. A proposed '1.5°C Pathway Scenario' involving aggressive electrification and clean energy standards could achieve net-zero emissions before 2050, while generating over 11,000 job-years and increasing annual GDP by more than $2.6 billion by 2050.

The Canadian Climate Institute states that Canada now has a credible climate plan aligned with its 2030 goals. The centerpiece is a carbon price increasing to $170/tonne by 2030, which the Institute argues minimizes overall economic costs while maintaining industrial competitiveness through production-based pricing. While the plan includes regulations for fuels, vehicles, and electricity, and supports low-carbon technologies, the Institute identifies a lack of a comprehensive national adaptation strategy as a remaining gap.

The Canadian Climate Institute asserts that Canada now possesses a credible climate plan capable of meeting its 2030 targets. The centerpiece of this strategy is a nationwide carbon price projected to reach $170/tonne by 2030, which the Institute claims minimizes overall economic costs while driving low-carbon innovation. The plan includes output-based pricing to maintain industrial competitiveness and quarterly rebates to ensure household affordability. While the document notes the inclusion of regulations for fuels, vehicles, and electricity, it identifies the lack of a national adaptation strategy as a current gap in the overall strategy.

The UK's decision to increase its 2030 emissions reduction target to at least 68% compared to 1990 levels is framed as a positive signal for business investment and economic growth. The author asserts that a zero-carbon transition is the most effective way to drive job creation and GDP growth during the recovery from the Covid-19 pandemic, outperforming traditional stimulus measures. The text highlights the role of the Science Based Target initiative, with over 1,060 companies committing to Paris Agreement-aligned decarbonization plans, and calls for clear roadmaps incorporating finance and just transition principles to maximize competitiveness.

ClientEarth argues that the revised IPCEI Communication must align with the European Green Deal by mainstreaming climate protection and excluding fossil fuel projects. The organization recommends that eligibility for aid be contingent on strict environmental compliance, the 'Energy Efficiency First' principle, and the production of hydrogen exclusively from 100% renewable sources. Additionally, ClientEarth calls for increased transparency in the State aid process, including the publication of pre-notification files and the implementation of competitive tenders to select beneficiaries.

The Clean Air Task Force proposes a federal policy platform to reach net-zero greenhouse gas emissions by 2050 through the deployment of zero-carbon technologies, strong regulatory standards, increased RD&D funding, and targeted financial incentives. Key priorities include achieving 100 percent zero-carbon electricity, reducing oil and gas methane emissions by 65%, and transitioning away from unabated fossil fuels while supporting vulnerable and fossil-fuel-dependent communities.

ClientEarth argues that EU competition policy must be reshaped to internalise environmental externalities and support the Green Deal. The organization calls for an end to state aid for fossil fuels, a more holistic 'consumer welfare' test in antitrust and merger assessments that includes future generations, and increased transparency in state aid decision-making. It specifically recommends prohibiting aid to forestry biomass and fossil-based hydrogen, while introducing a 'green bonus' to incentivize truly sustainable innovation.

The document advocates for clean fuel standards to decarbonize the transportation sector, which is the largest source of global warming pollution in the US. It explains how these standards use carbon intensity (CI) and a credit/deficit system to make clean fuels more affordable and polluting fuels more expensive. The text highlights the California Low Carbon Fuel Standard as a successful model and emphasizes the need for an equitable transition that benefits overburdened communities.

The Clean Air Task Force (CATF) supports the European Commission's proposed Carbon Border Adjustment Mechanism (CBAM) as a tool to prevent carbon leakage and encourage global climate action. CATF argues that a CBAM must replace the free allocation of certificates under the European Emissions Trading System (ETS) and be paired with innovation policies for advanced decarbonization technologies. The organization specifically warns against including methane in the ETS due to the complexities and potential counter-intuitive effects of Global Warming Potential (GWP) time horizons. CATF recommends that the CBAM apply to all imported energy based on verifiable greenhouse gas intensity, exempt Least Developed Countries and Small Island Developing States, and reinvest all revenues into climate innovation both within the EU and in developing countries.
