The report examines four scenarios for extending the EU ETS aviation scope beyond intra-EEA flights, potentially increasing revenues up to 1,160 billion € by 2040. It argues that including non-CO2 effects and private jets would significantly boost funding for sustainable aviation fuels (SAF), rail infrastructure (TEN-T), and international climate finance (NCQG).

The Clean Air Task Force contends that the Senate's version of the 45Z clean fuel production tax credit acts as a giveaway to mature biofuel industries while hindering the development of sustainable aviation fuels (SAF) and clean hydrogen. The authors argue that refocusing 45Z on advanced aviation fuels would reduce government spending and allow for the restoration of the 45V clean hydrogen production tax credit, which is essential for U.S. competitiveness against China in the global clean fuels market.

The report examines the impact of clean industrial hubs in California and Texas on first-of-a-kind projects, noting that 50% of supported projects reached a final investment decision compared to a 20% global average. It argues that these hubs mobilize investment and reduce emissions by creating enabling ecosystems for innovative first movers across sectors such as hydrogen, sustainable aviation fuel, and low-emissions steel.

The document outlines the difficulties of decarbonizing commercial aviation, noting that it contributes nearly 4% of historical global warming when non-CO2 effects are included. It highlights the limitations of sustainable aviation fuels (SAF) and electric aircraft, the disproportionate impact of frequent flyers, and the prevalence of greenwashing in the industry.

The document outlines the difficulty of decarbonizing commercial aviation, noting that while it contributes around 4% of all-time global warming, it lacks the immediate clean technological fixes available to other sectors. It highlights the limitations of sustainable aviation fuels (SAF), the outsized impact of frequent fliers, and the role of non-CO2 emissions like contrails. The guide encourages reporters to scrutinize industry greenwashing, report on how climate change increases flight turbulence and heat-related disruptions, and consider demand reduction as a necessary strategy to meet 1.5 degrees Celsius targets.

The document proposes an "energy park" model that co-locates renewable generation with flexible industrial loads and long-duration storage to replace retiring coal capacity. Using Pueblo, Colorado, as a case study, the authors model a system combining 2,000 MW of solar, 1,600 MW of wind, short-duration batteries, and flexible loads (thermal batteries and electrolyzers). The findings indicate that such a park can achieve 99% reliability in mimicking the dispatch of the Comanche Unit 3 plant while providing significant local economic benefits, including over $40 million in annual property taxes and 350 permanent jobs. Financially, the energy park is estimated to be at least 50% cheaper for electricity ratepayers than a comparable small modular nuclear reactor.

The report finds that Eni's strategy prioritizes oil and gas expansion and shareholder returns over renewable energy investments. Eni's projected 2030 production levels and LNG capacity expansions significantly overshoot NZE requirements, while its diversification into renewables remains marginal, representing only 5.8% of its projected 2030 energy mix.

The report argues that TotalEnergies' investment and production strategies prioritize oil and gas expansion and shareholder returns over climate solutions, leading to a significant overshoot of the IEA's Net Zero Emissions by 2050 Scenario.

Carbon Market Watch warns that watering down the EU ETS and Sustainable Aviation Fuel (SAF) mandates in response to airline industry pressure would increase emissions and undermine EU clean tech competitiveness. The author calls for extending SAF funding to 2040, expanding the EU ETS to all departing international flights, and implementing penalties for fuel suppliers who fail to meet SAF targets.

The report examines non-CO2 aviation effects, specifically contrails, which contribute to surface warming at a rate potentially similar to CO2 emissions. It evaluates three primary mitigation strategies: reducing aromatics in conventional fuel, increasing SAF adoption, and implementing flight path deviations to avoid ice-supersaturated regions (ISSR). While fuel hydrotreatment can reduce soot, the report warns that the energy-intensive process may increase CO2 emissions, potentially offsetting climate gains. SAF is presented as a more effective long-term solution, with targeted use on high-impact flights offering 9-15 times the benefit of low-level global blending. Operational mitigation via AI and satellite-based re-routing shows promise, though it faces challenges from air traffic congestion and weather forecasting inaccuracies. The document concludes that a combination of these technologies and specific non-CO2 policies is necessary to reduce the sector's total climate impact.

Brazil has announced a new NDC targeting a greenhouse gas emissions reduction of 59–67% by 2035 relative to 2005 levels. To achieve this, the government is developing a 2024-2035 Climate Plan consisting of an Adaptation Plan and a Mitigation Plan. The document argues that private sector investment is essential for success and recommends harmonizing sectoral policies, promoting corporate transition plans, and strengthening public-private dialogue. Key focus areas include halting illegal deforestation, decarbonizing agriculture, transitioning energy and industry away from fossil fuels, and implementing a national Emissions Trading System (ETS).

Federal clean energy incentives have already spurred $75 billion in private investment and created over 100,000 manufacturing jobs since 2022. Under a 'High Potential Scenario', these incentives could bring nearly $235 billion in federal investment to US states by 2030, with the largest gains expected in battery manufacturing and hydrogen production.

The document analyzes how international agreements, regional legislation, and industry competition hinder the removal of fossil fuel subsidies in aviation and shipping. It argues that while fuel taxation is often restricted by bilateral agreements or regional directives like the EU's Energy Taxation Directive, emissions levies through the ICAO and IMO offer viable pathways to reduce greenhouse gas emissions and fund the transition to sustainable fuels.

The Federal Hydrogen Hub Program aims to establish a national hydrogen network through seven regional hubs, with funding distributed across four phases over 8-12 years. While hubs claim local economic and environmental benefits, the guide notes that many proposed projects may increase pollution or waste energy. As of January 28, 2025, the DOE has instructed all recipients to cease activities related to Community Benefits Plans, pending further guidance.

The U.S. government utilizes programs like CLEEN, ASCENT, and NASA's flight testing to advance sustainable aviation. The Continuous Lower Energy, Emissions, and Noise (CLEEN) program focuses on aircraft electrification, advanced wing materials, and emission reductions, with the first two phases expected to reduce fuel consumption by 51.1 billion gallons by 2050. The Aviation Sustainability Center (ASCENT) coordinates universities and private stakeholders on sustainable aviation fuels and airworthiness standards. Additionally, NASA and Boeing are developing the X-66A experimental aircraft to test the Transonic Truss-Braced Wing Design, which could reduce fuel consumption and emissions by up to 30% compared to current single-aisle airliners.

The report analyzes the lifecycle emissions of polyester t-shirts to identify decarbonization opportunities for chemical producers and retailers. It argues that defining emissions reduction thresholds at upstream stages, such as the PET resin step rather than the fabric step, is essential to stimulate investment in low-emission chemical production. The analysis categorizes solutions into near-term operational changes (reducing up to 47% of footprints), near-term capital investments (reducing 31%), and long-term innovations (reducing 13-28% or up to 45% with transformative feedstocks). To derisk these capital-intensive transitions, the report suggests aggregated demand from multiple sectors (automotive, healthcare, construction), the formation of buyers alliances, and the implementation of green public procurement, noting that a 10-50% shift in US military procurement for polyester and nylon equipment could represent $100-$500 million in spending.

California's industrial permitting process is described as long and complicated, creating 'nonproductive friction' that can delay or cancel clean industrial projects. The document argues that because industry accounts for 23% of the state's emissions, streamlining these processes is essential for meeting climate goals. It suggests a dual approach: permit-seekers should prioritize industrial-zoned sites and proactive community engagement, while policymakers should standardize processes through GO-Biz, investigate centralized permitting for first-of-a-kind technologies, and reform the California Environmental Quality Act (CEQA) to remove redundancies.

The policy brief proposes that Cyprus leverage its unique island profile and Mediterranean position during its 2026 EU Council Presidency to advance EU-level action on water scarcity, climate adaptation, energy security, and transport decarbonisation. Key recommendations include establishing a Mediterranean Resilience Summit, a Water & Climate Security Forum, and an EU-SIDS Compact 2030, while steering legislative processes such as the Energy Security Framework and ETS revisions to support affordability and resilience.

Kazakhstan's NDC 3.0 sets a target to reduce net greenhouse gas emissions by 17% below 1990 levels by 2035 unconditionally, and up to 25% with international support. The plan aligns with a long-term goal of carbon neutrality by 2060 and emphasizes a transition from coal-dependency toward renewable energy, nuclear power, and energy efficiency. The document details sectoral mitigation measures, adaptation strategies for water and agriculture, and a framework for addressing loss and damage. Implementation is supported by a revitalized Emissions Trading System (ETS) and a proposed Carbon Fund, with total indicative investment needs for 2026–2035 estimated at USD 175.6 billion.

Brazil possesses a significant carbon competitiveness advantage due to its renewable-heavy electricity grid, but faces substantial risks from incoming Carbon Border Adjustment Mechanisms (CBAMs) and the EU Deforestation Regulation (EUDR). While 78% of its exports go to net zero-aligned markets, structural contradictions—such as continued fossil fuel exploration and the 'Devastation Bill'—threaten its climate credibility. The economy is heavily dependent on China, and recent unilateral tariffs from the US have introduced significant geopolitical volatility.
