The Center for International Environmental Law (CIEL) presents a critical overview of Carbon Capture and Storage (CCS), asserting that the technology overpromises on emission reductions while introducing significant safety risks and high costs. The document highlights the 'energy penalty'—the extra energy required to power capture equipment—and notes that most existing projects are used for enhanced oil recovery (EOR), which can increase overall emissions. It warns that a large-scale CCS buildout in the United States would require an unrealistic and dangerous expansion of pipeline infrastructure. Furthermore, the text argues that CCS is unnecessary for 'hard to abate' industrial sectors, where electrification and demand reduction are more viable, and critiques 'blue hydrogen' as a means to prolong fossil fuel dependence. The document concludes that global capture capacity is negligible compared to total emissions and that public subsidies, such as the US 45Q tax credit, inappropriately support the fossil fuel economy.

The document outlines a study aimed at filling a knowledge gap regarding the environmental and health impacts of air pollution within Cambodia's garment sector. Based on interviews with 323 workers across 16 factories and 16 factory owners, the research seeks to inform policymakers on improving occupational air pollution and upholding worker health as a human right. The brief notes that while the garment sector is an economic backbone, it is a highly polluting industry emitting pollutants through energy use, waste, and wastewater.

The steel sector is the highest CO2 emitter among heavy industries, accounting for 11% of global CO2 emissions. The report highlights that the dominant blast furnace to basic oxygen furnace (BF-BOF) route is highly carbon-intensive due to its reliance on metallurgical coal. To meet the 1.5°C target, the IEA suggests steel emissions must drop by 25% by 2030 and 92% by 2050. The document emphasizes a critical investment window, as over 70% of existing coal-fired blast furnaces need refurbishing by 2030. Reclaim Finance recommends that financial institutions end support for new metallurgical coal mines and coal-based steel facilities, instead prioritizing electric arc furnaces (EAF) and hydrogen-based direct reduced iron (HDRI).

The document examines air pollution in 16 Cambodian garment factories, finding that while particulate matter levels generally complied with national standards and WHO guidelines on the day of assessment, wood-burning factories were the most polluting. It highlights a significant gap in worker awareness, as 99% of interviewed workers perceived air quality as satisfactory despite all reporting symptoms related to air pollution. The brief emphasizes the gendered nature of the sector, where a predominantly young female workforce faces specific health risks, and recommends strengthening national air quality standards to align with WHO guidelines and implementing gender-inclusive occupational safety policies.

The document highlights the necessity of CCS for the Netherlands to meet its goal of reducing CO2 emissions by 55% by 2030 and 95% by 2050. It focuses on the Porthos project, which will transport and store CO2 from the Port of Rotterdam in empty North Sea gas fields, potentially reducing 2.5 Mt of CO2 per year. Porthos is presented as a first-mover project that can unlock further emissions reductions in the Netherlands and Europe.

Carbon Market Watch argues that the European Commission's proposal to revise the Industrial Emissions Directive (IED) fails to meaningfully address greenhouse gas (GHG) emissions because it maintains the exclusion of GHGs from installations covered by the EU Emissions Trading System (ETS). The organization recommends deleting Article 9.1 to allow binding emission limits for ETS sectors, maintaining the deletion of Article 9.2 to make energy efficiency requirements mandatory, and strengthening the requirements for industrial transformation plans (TP) to ensure they are binding, detailed, and implemented before 2030.

The document advocates for a shift from voluntary agreements to mandatory EU regulations to tackle microplastic pollution. It emphasizes reducing virgin plastic production and implementing sector-specific bans and design requirements for pellets, textiles, tyres, and agriculture. The authors argue that addressing both macro and microplastics is essential, as the degradation of larger plastics continues to fuel microplastic pollution.

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 testimony asserts that CCUS is not a viable climate solution, citing its failure to meet capture targets, high costs compared to renewables, and the risk of increasing lifecycle emissions. It highlights that most captured carbon is used for Enhanced Oil Recovery (EOR), which produces more CO2 than it captures. The author warns of significant safety risks from CO2 pipelines and the environmental dangers of offshore storage in the Gulf of Mexico, where legacy oil and gas wells increase the likelihood of leaks and ocean acidification.

The document highlights the dependency of the European wind industry on steel, noting that turbines consist of at least 70% steel. It argues that while wind energy is critical for the EU's energy transition, the steel production process remains highly carbon-intensive, emitting 1.85 tonnes of CO2 per tonne of steel in 2020. Using the example of Dirostahl in Remscheid, the brief illustrates the technical and financial barriers to switching from fossil gas to hydrogen or carbon capture and storage (CCS), specifically citing a potential price increase of 700 to 800 Euro per tonne of steel if switching to renewable hydrogen. It calls for the development of hydrogen and CO2 pipeline infrastructure and the implementation of policy tools like Carbon Contracts for Difference to maintain industrial competitiveness during the transition.

The EU ETS is a 'cap and trade' system covering power, industry, and aviation across the EU and several other European nations. While it has successfully reduced emissions in the power sector, the document argues that free allocation of permits has led to stagnant industrial emissions and significant windfall profits for companies. The guide details the role of the Market Stability Reserve in managing oversupply and discusses the proposed Carbon Border Adjustment Mechanism as a potential replacement for carbon leakage protections.

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.

The briefing argues that increasing the 45Q tax credit from $50 to $85 per metric ton would significantly increase industrial carbon capture, potentially reducing annual CO2 emissions by 22 to 36 million metric tons by 2031, particularly in hard-to-abate sectors like cement and steel.

The analysis of G20 climate policies between 2000 and 2019 reveals that while the number of mitigation policies has increased, significant adoption gaps persist across all sectors. Approximately half of the 50 identified key policy options are not widely adopted, leaving at least one-tenth of G20 emissions completely uncovered by policy.

The report details how systemic racism in Kansas City has led to the disproportionate siting of polluting industries in communities of color and low-income areas, resulting in severe health disparities. It highlights the failure of federal and state air monitoring networks to capture local pollution 'hot spots' and describes the efforts of CleanAirNow to implement community-based monitoring. The document concludes with recommendations for stricter emissions standards, real-time fenceline monitoring, and the transition to zero-emissions transportation to protect vulnerable residents.

Ethylene oxide (EtO) is a colorless, flammable gas used primarily for sterilizing medical equipment and as a chemical building block. Classified as a carcinogen by the EPA and other bodies, chronic inhalation is linked to white blood cell cancers and breast cancer. The document highlights that EtO emissions disproportionately affect low-income communities and people of color, with some areas in Louisiana experiencing cancer risks over 200 times the EPA's acceptable levels. While the EPA has updated the Miscellaneous Organic Chemical Manufacturing (MON) rule, the document argues that current regulations fail to require fenceline monitoring or a complete phaseout of the chemical, calling for stronger enforcement and the adoption of less toxic alternatives.

The Clean Air Task Force argues that Germany requires a dedicated CO2 strategy and regulatory framework to enable the implementation of CCU and CCS technologies, which are deemed essential for mitigating industrial process emissions that cannot be otherwise reduced. The document calls for the development of national and cross-border CO2 transport infrastructure, the introduction of Carbon Contracts for Difference (CCfD) to support industrial clusters, and the initiation of a societal dialogue on climate protection technologies.

The report finds that the Bargny-Sendou area already suffers from severe air pollution, with PM10 levels exceeding national standards by 193% to 540% before the full operation of new industrial projects. It argues that the cumulative impact of the coal plant, mineral port, and steel plant will exacerbate health risks and degrade local resources, including the livelihoods of 1,000 women processing fish at the Khelcom site. The study recommends a strategic environmental assessment of the zone and the conversion of the coal plant to gas.

The document advocates for the strategic use of "blue" hydrogen to accelerate decarbonization in sectors like heavy trucking, shipping, and steel production. It argues that relying solely on "green" hydrogen (electrolysis via renewables) would require an impractical increase in wind and solar capacity—potentially 40 times current U.S. levels—and excessive land use. While acknowledging that blue hydrogen's climate benefit depends on high carbon capture rates and low upstream methane leaks, the author asserts that these technical goals are feasible today. The document concludes that policymakers should implement tiered incentives tied to lifecycle greenhouse gas performance to ensure hydrogen production actually supports net-zero goals.

The report evaluates the impact of SO2 emissions from large solid fuel combustion installations in South Africa, primarily those operated by Eskom and Sasol. It concludes that implementing stricter emission standards is technologically feasible and economically beneficial for society due to significant reductions in public health costs, despite the high capital costs for plant operators. The panel recommends a flexible regulatory approach where emission limits are tailored to the remaining lifetime of each plant, suggesting that plants operating beyond the mid-2030s should meet stricter limits of 250 mg/Nm3 or 500 mg/Nm3, while those retiring sooner may be granted more lenient limits of 1000 mg/Nm3. The report highlights that 'expedited retirement' of older coal capacity could reduce retrofit costs by approximately 25% and minimize electricity tariff increases.
