The document outlines a Partner Reported Opportunity (PRO) to reduce methane venting at compressor stations by moving fire gate valves closer to the facility. This relocation reduces the length of the pipeline isolated from the facility, thereby decreasing the volume of gas released through Emergency Shutdown (ESD) systems. One partner reported reducing methane emissions by nearly 7.1 million cubic feet within one year across three facilities. The economic analysis suggests that for a 24-inch pipeline with a 2,000-foot isolation length at 900 psia operated four times annually, methane savings can reach 1,700 thousand cubic feet per year, with investment costs potentially ranging from under $1,000 to over $10,000 and payback periods between 0 and 10+ years.

The document outlines a Partner Reported Opportunity (PRO) to install pressurized storage tanks for condensate, preventing methane from flashing into the atmosphere when condensate is transferred from high-pressure pipelines to atmospheric tanks. This practice allows for the economic recovery of condensate and associated gases. A partner reported that installing four pressurized tanks saved 27,992 thousand cubic feet of methane annually, with a single 400-barrel tank saving 7,000 thousand cubic feet per year. The primary benefit is the reduction of VOC and HAP emissions, with investment costs reported at $37,500 in 1998 and a payback period of two years through recovered methane revenue.

The document outlines a practice to reduce methane emissions by increasing the replacement frequency of turbine meter measurement modules from every two years to every three years. This change reduces the number of times pipelines must be blocked and gas vented to the atmosphere for maintenance. A partner reported that for a pipeline with 519 meters, this practice saved 38 thousand cubic feet of methane annually. The primary benefit is identified as the reduction of labor costs, with an estimated annual methane saving of 27 thousand cubic feet for a baseline of 500 meters operating at 900 psig.

The document outlines a methane reduction opportunity (PRO No. 204) involving the replacement of glycol dehydrators with cyclone separators and in-line heaters. In this process, natural gas expands in a cyclone separator to cool and condense water vapor, which is then reheated to a specific dew point. This eliminates the need for glycol, thereby avoiding the methane emissions associated with glycol dehydrator operations. The technology is suitable for transport and distribution systems in cold environments, provided there is sufficient upstream pressure and a power source for resistive heaters. One partner reported saving 1,930 thousand cubic feet of methane by replacing 14 dehydrators. Economic analysis suggests a strong return on investment, with annual methane reductions of 130 thousand cubic feet for a system processing 10 million cubic feet of gas per day (reducing water vapor from 7 to 4 lbs/MMcf).

The document argues that traditional investor-owned utility (IOU) financing for transmission projects risks increasing consumer rates and proposes public financing as a lower-cost alternative. Research focused on California indicates that a "lease-type" public-private partnership could save ratepayers up to $3 billion annually, or $123 billion over 40 years, by utilizing low-cost public debt, reducing taxes, and maintaining private sector operational efficiency. The brief outlines several public financing mechanisms, such as public bonds and loans, and provides policy recommendations for other states to implement similar cost-saving reforms, including the use of credit enhancements and the designation of state-level coordinators for high-priority transmission lines.

The document examines the application of environmental taxes, fees, and charges across different sectors in the U.S., including water, air, solid waste, and hazardous waste management. It distinguishes between revenue-raising taxes and cost-offsetting fees, noting that while many instruments are designed to recover administrative costs, some—such as the federal tax on ozone-depleting chemicals and certain state-level hazardous waste taxes—have demonstrated significant incentive effects in reducing pollution. The report also details specific state-level experiments with variable-rate waste collection and wetland compensation fees.

The report argues that a rapid transition to a 1.5°C pathway is more economically beneficial than a slow one, as renewable energy costs are now lower than fossil fuels. It proposes three policy pillars—speed, steering, and simplification—to mobilize private capital and align economic development with climate goals. Key recommendations include establishing national carbon budgets, mandating transition plan disclosures, reforming carbon pricing, and utilizing blended finance and guarantees to reduce risks for investors, particularly in emerging markets.

The Regulatory Assistance Project (RAP) and ClientEarth challenge the UK government's (DECC) justification for a market-wide Capacity Mechanism, asserting that the analysis of generation adequacy is overly conservative and ignores the potential of demand response and interconnectors. They argue that a targeted strategic reserve would be a more cost-effective and less distortive alternative, especially given Ofgem's planned reforms to the Balancing Mechanism which would introduce stronger scarcity pricing signals.

The paper argues that Canada should move beyond textbook definitions of fossil fuel subsidies to evaluate policies based on their consistency with a low-carbon transition, value for money, employment outcomes, and policy fit. It highlights that public investment in long-lived fossil fuel assets now carries significant risk of becoming stranded as global demand for coal, oil, and gas inevitably declines. The authors recommend that Canadian governments pivot economic strategies toward transition-consistent business lines and prioritize the reform of new or highly obstructive measures, such as British Columbia's support for oil, gas, and coal development.

The document outlines a strategy for Canada to achieve a net-zero electricity sector by 2050, noting a sharp divide between 'clean' provinces (e.g., Quebec, Ontario) and those reliant on fossil fuels (e.g., Alberta, Saskatchewan). It proposes five key technical trajectories: increasing variable renewable energy, securing clean firm capacity, enhancing interprovincial transmission, improving demand flexibility, and deploying long-duration storage. The author argues that while the economic cost of wind and solar has plummeted, the primary barriers are now financial uncertainty regarding carbon pricing and the technical need for firm capacity and seasonal storage to manage intermittency.

The document provides an introductory overview of wind and solar energy, detailing how photovoltaic and turbine technologies convert natural elements into electricity. It highlights the transition from utility-scale to rooftop installations, the challenge of intermittency, and the significant cost reductions in solar and battery technology between 2009 and 2019. The text argues that renewables support more jobs per unit of electricity than fossil fuels and are essential for reaching net-zero emissions to avoid dangerous global warming.

The research paper assesses the carbon footprint and economic drivers of China's aluminium and steel industries. It highlights that primary aluminium production contributes significantly to global GHG emissions, particularly when accounting for coal-fired electricity. The paper also examines how export VAT refund rates and trade policies influence the production and export of these metals, using data from the World Bank and China Custom House to illustrate trends between 2003 and 2008.

The document assesses the challenges of the EU's proposed CBAM based on incurred emissions, noting that it fails to fully address carbon leakage for exports and value chains. It proposes an alternative 'climate contribution' based on standardised carbon intensity factors, which would act as an excise charge that can be passed along the supply chain and waived for exports. This model, combined with Carbon Contracts for Difference (CCfDs) funded by CBAM revenues, is presented as a way to create immediate investment incentives for climate-neutral production of materials like steel, cement, and aluminium.

The report critiques CBAM designs based on incurred emissions due to legal, administrative, and economic risks, such as resource shuffling and export leakage. It proposes a three-pillar alternative: a 'climate contribution' charge on basic materials, dynamic free EU ETS allowance allocation conditional on transition plans, and Carbon Contracts for Difference (CCfDs) to fund the incremental costs of clean production. This framework aims to provide effective carbon price signals across the value chain and support an inclusive transition across all EU industrial regions.

The briefing paper contends that carbon prices in Phase III of the EU ETS will likely fall in the lower end of the €20-40/tCO2 range, contradicting higher projections from the European Commission and other modelling studies. The author bases this on historical evidence showing that costs for environmental regulations—such as CFC phase-outs and sulphur dioxide trading—are consistently overestimated. The analysis highlights that current models often fail to account for the synergy between the EU's carbon cap and its other policy pillars, specifically the 20% energy efficiency target and renewable energy directives. Furthermore, the document notes that the 2007-2008 economic crisis, characterized by lower growth forecasts and higher fossil fuel prices, will further depress emissions and carbon prices. The author also points to the potential for a price collapse if the EU increases its acceptance of international credits from the Clean Development Mechanism (CDM).

The document argues that the EU's 2030 framework must combine price-based instruments with structural and behavioural policies to drive decarbonisation. It suggests reforming the EU ETS to better signal long-term scarcity and phase out coal, introducing new auctioning and project-based mechanisms for non-ETS sectors to ensure liquidity and transformation resources, and establishing a streamlined governance mechanism for Member State coordination through national decarbonisation plans.

Climate Strategies proposes that the EU 2030 framework must move beyond a single greenhouse gas target to a three-pillar system: standards and engagement (Pillar I), markets and pricing (Pillar II), and strategic investment for innovation (Pillar III). The authors argue that relying on any single pillar is self-defeating and that a hybrid price-and-quantity instrument for the EU ETS is necessary to provide the stability required to attract institutional investment. This framework is presented as a means to stimulate economic growth and utilize surplus private capital for low-carbon infrastructure.

The document analyzes Brazil's unique energy landscape, where a predominantly renewable electricity mix coexists with a significant reliance on petroleum for transport and a growing oil production sector. It highlights the tension between the government's climate commitments and its plans to expand oil production, particularly in the Equatorial Margin. The briefing suggests that Brazil can leverage its G20 and COP30 leadership to promote the reduction of fossil fuel subsidies and use oil revenues to fund green innovation and forest conservation, while recommending the introduction of an upstream carbon tax to manage environmental externalities.

The report argues that deep decarbonisation of EU energy-intensive industries requires a combination of process innovations, product shifts, and business model transformations. For chemicals, this involves transitioning to bio-based feedstocks and enhanced plastics recycling. In steel, the HIsarna process and a shift toward electric arc furnace (EAF) production from scrap are highlighted. For cement, the report emphasizes calcium looping carbon capture and storage (CCS) and clinker substitution. It concludes that public policy, specifically the EU ETS Innovation Fund, is essential to bridge the gap between demonstration and commercialisation of these technologies by 2030.

The fact sheet outlines the economic and environmental benefits of energy efficiency in Michigan, highlighting its role in meeting federal air regulations and reducing utility costs. It cites a Michigan Public Service Commission analysis showing a return of $4.38 in utility savings for every $1 spent on efficiency programs. The document projects that by 2030, a combination of 1.5% annual energy savings, national model building codes, and 500 MWs of new combined heat and power could save Michigan $5.5 billion and avoid over 21 million tons of carbon dioxide.
