The report analyzes the total value of adopting energy-efficient computers, using the IBM PS/2 E as a benchmark. It demonstrates that such machines reduce direct energy use by approximately 80% during office hours and lower secondary energy needs for cooling and power distribution. Beyond utility savings, the author highlights substantial capital cost reductions in air-conditioning and wiring for new and renovated buildings. Environmentally, the report quantifies the reduction in CO2, SOx, and NOx emissions. Finally, it suggests that the elimination of fan noise, radiant heat, and screen flicker, combined with better ergonomics, can lead to productivity gains that may outweigh all other economic benefits.

The Clean Air Task Force (CATF) contends that the EPA's proposed MACT standards for coal-fired utility units violate the Clean Air Act (CAA) by using arbitrary subcategories based on coal rank and flawed statistical methods to inflate emission floors. CATF argues that the EPA has ignored available, cost-effective technologies—such as activated carbon injection and fabric filters—that could achieve significantly higher mercury removal rates. The document further asserts that the EPA is legally obligated to regulate all HAPs emitted by these units, not just mercury and nickel, and that proposed compliance extensions are unauthorized and unnecessary given available labor and equipment resources.

The document analyzes the climate impact of Arctic oil and gas production, focusing on short-lived climate forcers (SLCFs) like methane and black carbon. It details emission sources—such as associated gas flaring, venting from storage tanks, and diesel engine exhaust—and proposes mitigation strategies including vapor recovery units, diesel particulate filters, and the use of ultra-low sulfur diesel. The paper emphasizes that while some technologies are standard in lower latitudes, Arctic implementation faces higher costs and infrastructure challenges.

The document outlines the established safety protocols for transporting ammonia by sea and the necessary developments for its adoption as a marine fuel, emphasizing the management of its toxicity.

The Clean Air Task Force argues that the U.S. oil and gas sector must reduce methane emissions by 65% by 2025 to align with global goals for limiting warming to 1.5°C. Without further action, emissions are projected to reach nearly 12 million metric tons by 2025. The proposal focuses on three primary areas: implementing monthly leak detection and repair (LDAR) or continuous monitoring to address leaks and super-emitters; replacing gas-driven pneumatic equipment with non-emitting alternatives; and implementing additional controls on storage tanks, well completions, compressors, and flaring. Together, these measures would reduce emissions by almost eight million tons per year, a benefit the author compares to replacing 150 million gasoline cars with zero-carbon electric vehicles. The document also advocates for a national policy to supplement existing state-level regulations in Colorado, Pennsylvania, and New Mexico.

The document assesses the environmental and economic impacts of flaring associated gas in the Bakken and Eagle Ford formations, concluding that routine flaring is unnecessary due to the availability of mature alternatives like CNG trucking, NGL recovery, and gas-to-power generation. It argues that current regulations, such as those in North Dakota, are inadequate and calls for robust nationwide standards from the BLM and EPA to mandate gas capture.

The fact sheet outlines the role of carbon capture and storage (CCS) in decarbonizing Bulgaria's industrial sectors, particularly cement, chemicals, and refining. It highlights Bulgaria's high emission intensity in the EU and identifies significant geological storage potential, including the Pleven saline aquifer. The document details the ANRAV project as a pioneering CCS initiative in Eastern Europe and recommends the development of a comprehensive national carbon management strategy and the creation of low-carbon industrial clusters.

Bulgaria, the EU's most carbon-intensive economy, can use carbon capture and storage (CCS) to decarbonise its chemical, refinery, and cement sectors. While the country lacks a cohesive deployment strategy, it has a legal foundation via the EU CCS Directive and significant estimated storage capacity of 2.6 Gt. The ANRAV project, supported by a €190 million EU Innovation Fund grant, aims to be Eastern Europe's first full value chain CCS project, targeting a 95% emissions reduction from the Devnya Cement Plant by 2028.

Croatia aims for a 45% emission reduction by 2030 and climate neutrality by 2050, with the industrial sector contributing 2.76 MtCO2/year (16% of national emissions). The document highlights that cement production, accounting for 62% of industrial emissions, has no viable decarbonization path other than CCS. Croatia possesses a significant storage capacity of 4.2 GtCO2, primarily in saline aquifers (4 Gt) and depleted hydrocarbon fields (175 Mt), which is sufficient to store 693 years of the country's annual point-source emissions. To optimize deployment, the document proposes three industrial clusters: the Adriatic, Central, and Eastern clusters. Current initiatives include the Croatian Geothermal CCS project, which plans to store CO2 from the Našice cement plant and a plant in Beremend, Hungary, at the Bočkovci-1 site. Other projects in development include Petrokemija Kutina (190,000 tCO2/year), Biorafinerija Sisak (55,000 tCO2/year), and a cement plant in Koromač (400,000 tCO2/year). Collectively, these could capture 1.3 million tonnes of CO2 annually. Economically, implementing CCS in the Eastern cluster could save 1.2 billion euros in EU Emissions Trading System (ETS) costs. The document recommends simplifying permitting processes, developing a comprehensive carbon management strategy, and investing in storage site characterization and cross-border cooperation.

The document outlines Poland's position as the EU's third-largest greenhouse gas emitter and advocates for the deployment of carbon capture and storage (CCS) to decarbonize energy-intensive industries. It highlights Poland's significant geological storage potential, exceeding 15 Gt of CO2, and discusses specific projects like GO4ECOPLANET and ECO2CEE. The text emphasizes that developing domestic storage and transport infrastructure is critical to reducing costs and avoiding high EU ETS emission fees.

The document argues that carbon capture and storage (CCS) is a cost-effective solution for Portugal to reach carbon neutrality by 2045, particularly for hard-to-abate industries like cement and pulp and paper. It highlights a theoretical geological storage capacity of 7.09 GtCO2 and proposes the development of industrial clusters, specifically in the Lusitanian Basin, to scale the technology.

Spain has a significant CO2 storage potential of 12 to 44 Gt, which could accommodate 121 to 445 years of its annual point source emissions. While industrial point sources account for 49 MtCO2/yr (20% of national total), the Spanish Government has not yet provided specific plans for CCS deployment. The document highlights the Ebro Basin as a prime location where CCS could mitigate 4.42 MtCO2/yr by 2050 and create up to 104,900 jobs. To avoid competitive vulnerability as EU ETS prices rise, the report recommends a national carbon management strategy, streamlined permitting, and the development of low-carbon industrial clusters in regions such as the Ebro Basin, Vasco-Cantabrica Basin, and Huelva.

Poland is the EU's third-largest emitter, with industrial point source fossil emissions totaling 40.6 MtCO2/year. The document argues that CCS is essential for the decarbonisation of energy-intensive industries—particularly cement, steel, and fertilizer—and for providing firm power in a decarbonised energy grid. Poland possesses a significant CO2 storage potential of over 15 Gt, primarily in saline aquifers (14.3 Gt) and hydrocarbon fields (1 Gt), which could store 369 years of its annual industrial point source fossil emissions. Current projects like GO4ECOPLANET aim to decarbonise cement production at the Kujawy plant, with CO2 transported to the North Sea via the ECO2CEE project. The document highlights that developing domestic onshore storage and pipeline infrastructure could reduce transport and storage costs from €93-€100/t to between €23-€49/t. To accelerate deployment, the author recommends developing national storage resources, supporting projects to Final Investment Decision (FID) through mechanisms like carbon contracts for difference, and establishing cross-border partnerships with other EU Member States and Baltic countries.

Portugal has a theoretical CO2 storage capacity of 7.09 GtCO2, which could support the decarbonisation of its energy-intensive industries, particularly cement and pulp and paper. While no active CCS projects exist, the STRATEGY CCUS project has identified the Lusitanian Basin as a key area for cluster development. To accelerate adoption, the document recommends creating a national carbon management strategy, clarifying offshore maritime space permits, and establishing cross-border storage partnerships with EU member states like Spain.

The document outlines a Partner Reported Opportunity (PRO) to install velocity tubing strings in natural gas wells. By reducing the flow cross-sectional area and increasing flow velocity, these strings allow for liquid removal without venting methane to the atmosphere. The practice is most suitable for wells with relatively low liquid production and relatively high reservoir pressure. One reported case showed a methane saving of 4,680 thousand cubic feet per year by eliminating a bi-weekly venting practice that emitted 180 thousand cubic feet per well per event. Investment costs vary from under $1,000 to over $10,000, with payback periods ranging from 0 to over 10 years, typically recovering investment in less than 3 years through increased production and extended well life.

The document outlines the role of carbon management in North Rhine-Westphalia's transition to climate neutrality by 2045, highlighting that industrial point sources will still emit 7 million tonnes of unavoidable CO2 even with all technical measures except CCS. It identifies two key carbon management clusters—the Rhine Cluster and the Westfalen Cluster—and emphasizes the need for CO2 transport infrastructure and storage sites, potentially in the Netherlands (Porthos) or Norway (Northern Lights). The state government's strategy includes reducing CO2 intensity, developing CO2-free technologies, sustainable CO2 use, and public discourse.

The document advocates for a transition from heavy fuel oil and marine diesel to hydrogen and ammonia to reduce greenhouse gas emissions in the maritime sector. It criticizes LNG and methanol as unsustainable alternatives and calls for specific policy interventions in the Alternative Fuels Infrastructure Regulation (AFIR) and FuelEU Maritime to ensure infrastructure readiness by 2030 and create market incentives for zero-carbon fuels.

The Clean Air Task Force (CATF) recommends that the DOE prioritize a limited number of large-scale hydrogen hubs (4 to 6) to avoid program dilution and maximize industrial learning. CATF emphasizes the need for full lifecycle analysis (LCA) to measure greenhouse gas intensity, noting that natural gas with carbon capture can reach 1.5 to 2.0 kgCO2e/kgH2, while solar-powered electrolyzers range from 0.96 to 2.52 kgCO2e/kgH2 when upstream emissions are included. The document argues for prioritizing 'difficult-to-electrify' sectors such as heavy-duty trucking, marine shipping, and heavy industry. To ensure equity, CATF suggests requiring comprehensive community environmental health assessments and implementing inclusive engagement strategies to protect disadvantaged communities from industrial pollution.

The report analyzes methane emissions from LNG liquefaction, transport, and regasification, as well as small-scale distribution. It identifies key emission drivers such as fugitive leaks, boil-off gas (BOG) management, incomplete combustion in power generation and flaring, and gas-freeing during maintenance. The document provides a comprehensive set of best practices, including Leak Detection and Repair (LDAR) programs, the use of dry-disconnect couplings, reliquefaction units, and vapor recovery systems to minimize the climate impact of the LNG supply chain.

The livestock sector in Paraguay is a primary economic driver but also the largest source of national greenhouse gas emissions, with 50.3% of total emissions in 2021 coming from this sector and 76.2% of those being methane from enteric fermentation. To meet its goal of reducing greenhouse gas emissions by 20% by 2030, Paraguay is exploring strategies to increase productivity while lowering emissions. Implementing productivity-enhancing technologies could potentially increase income per hectare by 66% and reduce total greenhouse gas emissions by between 12.6% and 50%. Proposed actions include improving genetics, animal health, and pasture management to shorten production cycles, as well as establishing multisectoral working groups and green financial products, such as carbon markets and credit models similar to Brazil's Plan ABC/ABC+.
