The study evaluates three scenarios for the EU ETS in aviation: the European Commission's intra-European proposal, a 'semi scope' covering all departing flights, and a 'full scope' covering all incoming and departing flights. It finds that expanding the scope to all flights would reduce emissions by 113% compared to the Commission's proposal and generate significantly higher revenues—up to 107€ billion over 15 years—while carbon costs would remain a small fraction of airline operating costs. The document argues against reliance on the UN's Corsia offsetting scheme, citing its uncertainty and potential to reduce emission savings by 77% compared to expectations.

The report critiques the 'net zero' framework and the expansion of carbon offset markets, asserting that they create a false equivalence between carbon removals and avoided emissions. It argues that these mechanisms serve as a 'house of cards' designed to protect stranded fossil fuel assets by providing a veneer of climate action while allowing ongoing emissions. The document specifically highlights the efforts of the Task Force on Scaling Voluntary Carbon Markets (TSVCM) and the Architecture for REDD+ Transactions (ART-TREES) to standardize and commodify different types of carbon credits to increase market volume. It concludes that the only viable path to limiting warming to 1.5°C is a rapid, just transition to renewable energy and the immediate phase-out of fossil fuels, rather than reliance on speculative carbon removal technologies or flawed offsetting schemes.

The document critiques the 'fossil bet on the future,' claiming that carbon offsets and net-zero goals serve as a 'house of cards' to maintain fossil fuel dependence. It specifically targets the amalgamation of carbon capture, emission reductions, and avoided emissions into single, fungible credit units, arguing that such mechanisms do not actually reduce atmospheric CO2 and may lead to increased warming. The report highlights the role of the Task Force on Scaling Voluntary Carbon Markets (TSVCM) and ART-TREES in standardizing these credits to facilitate financial speculation and the 're-floating' of stranded assets.

The report argues that while Europe has significant theoretical CO2 storage capacity, actual deployment is hindered by a funding gap, regulatory barriers to cross-border transport, and a lack of coordinated infrastructure. It recommends shifting from project-based funding to system-based approaches, implementing carbon contracts for difference (CCfDs), and establishing a market for low-carbon products. The authors call for a formal EU strategy to set milestone targets and coordinate the development of large-scale, open-access storage sites beyond the North Sea.

Carbon Market Watch argues that Article 6.2 and 6.4 mechanisms lack a clear definition of "removals," leading to the risk of including "false solutions." The organization proposes four scientific principles for defining real removals: atmospheric GHG removal, permanent storage (at least 200-300 years), comprehensive accounting of process emissions, and a net-positive removal balance. Based on these, the document asserts that nature-based sequestration and point-source CCS do not qualify as permanent removals. It specifically critiques nature-based activities due to the impossibility of guaranteeing monitoring and liability for reversals over centuries, noting that buffer pools are inadequate. Instead, it suggests nature-based activities generate "Paris Agreement Support Units" to channel finance without allowing offset claims.

The document analyzes the resource requirements and potential externalities of direct air capture (DAC) at both a single-plant (1 MtCO2/year) and a system-wide (0.5 GtCO2/year) scale. It finds that while on-site emissions are low, significant impacts arise from energy demand, land use, and the materials supply chain. The authors argue that responsible scaling requires project-specific social and environmental impact assessments, robust community engagement, and the use of legal agreements like Community Benefits Agreements to ensure equitable distribution of benefits, such as job creation.

The Environmental and Energy Study Institute (EESI) hosted a briefing series titled 'Living with Climate Change' to address community preparation for polar vortices, sea level rise, wildfires, and extreme heat. A specific focus was placed on the polar vortex, noting that climate change is expected to affect the frequency and severity of these events. The document highlights the necessity of adaptation strategies for the energy grid and home energy efficiency to prevent deadly power losses, citing 246 deaths during the 2021 Texas polar vortex freeze.

RMI advocates for a comprehensive transformation of the global economy across ten key fronts to meet the 1.5C climate target. These priorities include increasing political ambition, decarbonizing buildings and transportation, phasing out coal and gas, scaling green hydrogen, and enhancing emissions transparency. The organization emphasizes the need for a three- to six-fold increase in zero-carbon capital investments and the integration of mitigation and adaptation efforts, particularly in the Global South, to ensure an equitable transition.

The briefing highlights that global greenhouse gas emissions continue to rise, making the Paris Agreement targets of 1.5°C and 2°C increasingly difficult to achieve without significant 'overshoot'. It notes a critical gap in climate finance, where current levels are roughly ten times lower than the estimated USD 6.3 trillion needed annually by 2030. While net-zero commitments and renewable energy deployment have grown substantially, the document warns against an over-reliance on carbon dioxide removal (CDR) and emphasizes the need for rapid transformations in energy, agriculture, and urban planning.

The policy brief contends that Germany cannot achieve climate neutrality by 2045 without carbon management technologies, including carbon capture and storage (CCS), direct air capture (DAC), and bioenergy with carbon capture and storage (BECCS). It highlights that current industrial emissions reductions are insufficient and that a lack of CO2 transport infrastructure and storage sites within Germany necessitates a strategy to connect to regional hubs in Northern Europe. The document further argues that carbon management is essential for decarbonizing the hydrogen economy—specifically through the use of blue hydrogen—and for producing the low-carbon industrial materials required for the renewable energy transition.

The report reviews 42 NDCs to identify national priorities for advanced low-emission technologies. It finds that 14 jurisdictions include carbon capture, utilization and storage (CCUS), 16 include low-carbon hydrogen and ammonia, and 11 prioritize nuclear energy. The analysis highlights a mix of developed and developing nations seeking these technologies, with some relying on international financial and technological support for implementation.

The report identifies significant gaps in the monitoring, reporting, and verification (MRV) infrastructure for carbon dioxide removal (CDR), noting that existing frameworks are primarily designed for emission reductions rather than removals. It highlights inconsistencies in how permanence, system boundaries, and additionality are treated across different voluntary and compliance standards. The authors recommend the development of dedicated methodologies for Direct Air Capture (DAC) and Bio-energy with carbon capture and storage (BECCS), the adoption of dynamic baselines aligned with Paris Agreement targets, and a standardized approach to defining 'permanent' storage to prevent the overestimation of mitigation results.

The report analyzes urban greenhouse gas emissions, focusing on the transportation and built environment sectors. It evaluates the annual emissions reduction potential of various efficiency-based technologies—such as electric vehicles, LED street lighting, and building retrofits—and explores carbon removal strategies, including artificial technologies and nature-based solutions. The analysis provides a baseline for both global and Swedish emissions to guide municipal policymakers in selecting high-impact decarbonization strategies.

The Middle East and North Africa (MENA) region is well-positioned to become a global leader in carbon management due to its existing technical expertise, financial resources, and geologic storage capacity. While current project numbers are low compared to the U.S. and Europe, the region has significant potential to scale up carbon capture to reduce industrial emissions and produce zero-carbon fuels like hydrogen and ammonia.

The testimony asserts that while electrification is critical, approximately 60% of U.S. energy-related CO2 emissions come from sectors like heavy industry and long-haul transport that are difficult to electrify. Hydrogen is presented as a versatile, carbon-free energy carrier capable of addressing these gaps. The author highlights specific opportunities in long-haul trucking, aviation, marine shipping, and ironmaking, while noting that the U.S. may require between 8 and 18 quads of hydrogen per year by 2050 for full decarbonization. To achieve this, the document advocates for federal R&D, the development of Regional Clean Hydrogen Hubs under the Infrastructure Investment and Jobs Act, and the implementation of production tax incentives to reduce costs through scaling.

The Inflation Reduction Act of 2022 establishes a series of tax incentives aimed at reducing greenhouse gas emissions to an estimated 42% below 2005 levels by 2030. These provisions cover clean electricity, including the extension of renewable energy credits and support for existing nuclear power; clean fuel production, specifically targeting clean hydrogen, renewable fuels, and sustainable aviation fuels; energy efficiency for homes and commercial buildings; and the adoption of clean vehicles. Additionally, the Act provides incentives for clean energy manufacturing to develop domestic supply chains for technologies such as carbon capture, solar, wind, and battery components.

The document argues that carbon offsetting is often used to justify continued emissions and delay the necessary phase-out of fossil fuels. It distinguishes between 'avoidance offsets', which are deemed incompatible with net zero goals, and 'removal offsets', which face significant challenges regarding permanence, additionality, and scale. The authors contend that the current carbon market reproduces global inequalities and risks negative social outcomes, particularly in land-based projects. They recommend that governments and businesses eliminate avoidance offsets, prioritize direct emission reductions, and fund necessary carbon removals through non-market mechanisms such as public financing or mandates.

The report establishes four core principles for verifying 'real' carbon dioxide removals: sourcing carbon from the atmosphere, ensuring permanent storage (at least 200-300 years), conducting comprehensive life cycle assessments of all associated emissions, and ensuring net-negative results. It argues against the 'false equivalency' that one tonne emitted equals one tonne removed, noting that removals may only undo up to 90% of an emission's impact and cannot reverse certain climate damages like sea-level rise. The author emphasizes that CDR should supplement, not replace, deep decarbonization to prevent 'mitigation deterrence,' where the promise of future removals slows current emission cuts.

The paper evaluates four scenarios—a Reference Scenario and three increasing levels of policy ambition—to determine the effectiveness of tax credits, infrastructure spending, and performance standards in decarbonizing the U.S. economy. It finds that while tax credits and spending drive early adoption, sector-specific performance standards and negative emissions technologies are essential to reach net-zero by 2050. The analysis concludes that decarbonization is economically feasible, with potential net savings of 0.3 percent of U.S. GDP by 2050 under reference oil prices.

CATF Executive Director Armond Cohen outlines the organization's efforts at COP26 to prioritize methane emissions reductions and the deployment of next-generation carbon-free technologies. Key achievements include the launch of the Global Methane Pledge and the inclusion of methane and coal 'phase down' language in the final COP26 text. The document emphasizes that meeting net-zero targets requires an expanded suite of technologies beyond renewables, including carbon capture, hydrogen, and advanced nuclear energy.
