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 briefing argues that Japan can mitigate its high reliance on energy imports—currently 99.7% for oil, 97.7% for LNG, and 99.6% for coal—by rapidly expanding domestic renewables and upgrading its national grid. It recommends implementing a JPY 7 trillion 'Master Plan' for interregional transmission to connect resources in Hokkaido and Kyushu to Tokyo. Internationally, the document urges Japan to lead ASEAN countries in transition and disaster resilience while ensuring its own transition measures remain science-based. It specifically warns against the use of LNG as a transition fuel due to methane leakage, noting one study found the GHG footprint of US LNG is 33% greater than coal using GWP20. Finally, it proposes leveraging Japan's financial sector and the GX Plan to make Tokyo a global hub for transition finance through supportive fund management rules and alignment with international standards.

The report argues that while US and EU cooperation on carbon pricing and tariffs (such as GASSA and CBAM) has stalled due to diverging political visions, a 'softer' path to alignment is possible. This approach prioritizes cooperation on 'carrots' like R&D and green public procurement, and 'sticks' like the harmonization of carbon standards. The study recommends expanding collaboration beyond hydrogen and carbon capture to include circular economy practices and industrial electrification, utilizing platforms like the Trade and Technology Council (TTC) to avoid duplication and establish common technology standards.

In 2024, WRI supported over 150 U.S. cities and counties in accelerating clean energy deployment and helped over 60 cities claim more than $12 million in tax credits via the Inflation Reduction Act's elective pay mechanism. The organization advanced next-generation geothermal technologies, launched a database of 50 community benefits frameworks for transmission projects, and supported the deployment of electric school buses (ESBs) through initiatives like the RVXDS project in California. WRI also focused on reforming power markets and grids, providing technical assistance to the PJM Cities and Communities Coalition and researching interregional transmission procurement.

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 document introduces the China Low-Carbon and Clean Technologies Outlook series, which analyzes 50 promising technologies to support China's carbon neutrality goal. It specifically highlights the need for significant investment in emerging technologies like energy storage and hydrogen, estimating a requirement of 100 trillion Yuan. This particular report presents the first four insight briefs focusing on power batteries, heat pumps, iron ore electrolysis, and flow battery energy storage.

The Electrical Utilities Criteria provide a framework for certifying entities and debt instruments based on their emissions intensity and transition pathways toward net-zero by 2040. The criteria distinguish between existing and new capacity, setting specific GHG thresholds for low-carbon technologies and phase-out dates for unabated fossil fuel plants. It also defines requirements for mitigation measures like CCS/CCUS and cofiring, as well as a comprehensive adaptation and resilience checklist to ensure infrastructure is robust against physical climate hazards.

Average annual climate finance reached nearly USD 1.3 trillion in 2021/2022, nearly doubling from 2019/2020 levels, though this remains only 1% of global GDP. Growth was primarily driven by mitigation finance in energy and transport, with significant concentration in China, the US, Europe, Brazil, Japan, and India. Adaptation finance, while reaching a record USD 63 billion, remains severely underfunded compared to the USD 212 billion annual need for developing countries by 2030. The report highlights a critical investment gap, noting that annual needs will increase to between $8.1 and $9 trillion through 2030, and over $10 trillion annually from 2031 to 2050.

The document argues that Saudi Arabia has spent three decades using procedural and substantive tactics to undermine UN climate negotiations and the IPCC scientific process. It details how Riyadh leverages consensus-based decision-making, raises opportunistic procedural objections, and contests climate science to delay the transition away from fossil fuels. The authors conclude by recommending structural changes to UN voting rules and increased transparency to combat such obstructionism.

The document critiques the global hydrogen industry, asserting that most production relies on fossil fuels and that even 'green' hydrogen is inefficient and risks perpetuating neocolonial extractivism. It argues that hydrogen serves as a distraction from necessary climate action and a tool for the gas industry to justify new infrastructure. The author calls for the elimination of fossil-fuel-based hydrogen and a transition to community-owned renewable energy and agroecology.

Friends of the Earth International positions hydrogen as a dangerous distraction from real climate action, asserting that most production relies on fossil fuels and that even 'green' hydrogen is inefficient and risks perpetuating neocolonial extractivism. The document critiques various 'colors' of hydrogen, warns against carbon capture and storage (CCS) as an unproven patch, and calls for a systemic shift toward energy sovereignty and community-led renewables instead of industrial hydrogen projects.

The document critiques the promotion of hydrogen as a clean energy alternative, asserting that the vast majority of global production relies on fossil fuels. It categorizes different 'colors' of hydrogen, arguing that grey, blue, black/brown, and turquoise versions perpetuate fossil fuel dependency, while green hydrogen is inefficient and risks replicating neocolonial extractivism. The paper highlights the high water and energy requirements of electrolysis and the unproven nature of Carbon Capture and Storage (CCS). It concludes that hydrogen serves as a distraction from deep systemic change and recommends a coordinated phase-out of fossil fuels and a transition to community-owned renewable energy.

The Union of Concerned Scientists (UCS) analysis finds that while the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) accelerate emissions reductions, additional policies are required to meet US climate targets. Achieving net-zero by 2050 requires a rapid phaseout of fossil fuels, a massive scale-up of wind, solar, and energy storage, and expanded electrification and energy efficiency. The report argues that the health and climate benefits of this transition—including avoided premature deaths and reduced climate-caused damage—significantly outweigh the energy system costs.

Reclaim Finance critiques the IEA's "clean energy" scope, asserting that several included technologies—such as CCUS, nuclear power, and solid biomass—are unsustainable due to high costs, environmental damage, or continued reliance on fossil fuels. The organization advocates for a narrower definition of sustainable power focused on solar, wind, ocean, and geothermal energy, as well as modernized grid infrastructure, and calls for banks to disclose detailed inventories of their energy transition financing.

RMI highlights that the perceived climate benefit of substituting coal with natural gas is undermined by methane leakage. The briefing notes that leakage rates as low as 0.2% can make gas emissions equal to coal, depending on the specific resources involved. To address this, RMI has developed a calculator for site-specific emissions parity analysis. The document advocates for immediate methane mitigation through technology and policy, noting that wind and solar are already more economically attractive and avoid the methane risks associated with gas.

The Climate Bonds Initiative evaluates Japan's GX Plan, noting that while it provides a solid foundation for transition finance, certain elements—specifically the reliance on ammonia co-firing and fossil gas—risk undermining its credibility. The report recommends prioritising mature renewable technologies, setting a clear phase-out date for unabated coal by 2035, and implementing a mandatory emissions trading system with a strong carbon price to ensure alignment with global 1.5°C goals.

Reclaim Finance argues that TotalEnergies' claims of diversification are misleading, as the company intends to increase oil and gas production through 2028 and expand its liquefied natural gas (LNG) capacity. The report highlights that the company's renewable energy growth is largely driven by acquisitions of existing projects rather than new construction, and that its 'clean' hydrogen and electricity goals still rely heavily on fossil gas. A specific case study on the Papua LNG project illustrates the potential for significant carbon emissions and human rights violations, while the report concludes by urging financial institutions to stop supporting new fossil fuel projects.

Reclaim Finance argues that TotalEnergies' claims of diversification are misleading, as the company intends to increase absolute oil and gas production by 2030 and is aggressively expanding its liquefied natural gas (LNG) portfolio. The report highlights that the company's renewable energy growth relies heavily on acquisitions rather than new capacity and criticizes the Papua LNG project for its projected climate and human rights impacts.

A survey of 58 European climate experts reveals skepticism about Europe's ability to meet its 2030 and 2050 climate goals, citing lagging investments and bureaucratic hurdles. While experts show varying confidence in technologies like CCS and hydrogen, there is a notable call for a more prominent role for nuclear energy and a shift toward 'technology optionality' and simplified, incentive-based policymaking.

The report identifies a 'planning gap' in Europe's trajectory toward 2050 climate neutrality and proposes that the updated National Energy and Climate Plans (NECPs) be transformed into comprehensive roadmaps. It recommends that Member States move beyond a narrow focus on renewables to include a diverse portfolio of clean firm energy (advanced nuclear, superhot rock geothermal), carbon capture and storage (CCS), and zero-carbon fuels. The authors emphasize the need for robust energy system modelling, cross-border infrastructure coordination, and the implementation of financial mechanisms like Carbon Contracts for Difference (CCfD) to attract investment. Additionally, the report calls for a focused strategy to reduce methane emissions from the oil and gas supply chain and the creation of a net-zero implementation tracker to ensure accountability.
