The guide explains the transition of the EU CBAM to its definitive phase in January 2026, emphasizing the financial impact on exporters of steel and aluminum. It highlights that the use of high default values for missing verified emissions data increases costs, while carbon prices paid in the country of origin can be deducted from CBAM liability.

The document outlines a comprehensive framework for LDAR programs, emphasizing that well-implemented programs can reduce methane leaks by nearly 80%. It details the technical application of OGI cameras, a structured nine-step survey process—from planning to data reporting—and a typology of common leak sources such as valves, flanges, and compressor seals. The guide also provides regulatory benchmarks for survey frequency, repair timelines, and reporting templates to ensure accountability and effectiveness in methane mitigation.

The EU's Carbon Border Adjustment Mechanism (CBAM) transitioned from a reporting-only phase to a definitive period on January 1, 2026, introducing financial liabilities for importers of iron, steel, aluminum, cement, fertilizers, electricity, and hydrogen. Exporters must now provide verified actual emissions data to avoid high default values, which include annual markups of +10% in 2026, +20% in 2027, and +30% from 2028 onward. Financial liability is calculated based on embedded emissions, adjusted by a Free Allocation Adjustment (FAA) that phases out by 2034, and monetized through CBAM certificates linked to EU ETS prices. The guide emphasizes that verified actual emissions and documentation of carbon prices paid in the country of origin are critical for maintaining competitiveness and reducing costs.

The methodology establishes a framework for the 'integrated replacement' of fossil-fuel generators (such as diesel or natural gas gensets and mini-grids) with greenfield renewable energy systems (RES), including solar PV, wind, and hydro. It mandates the permanent decommissioning of the baseline system and the implementation of a Just Transition Plan to protect affected workers and consumers. Emission reductions are calculated by comparing the RES output against a baseline of historical or default fossil fuel emissions, adjusted downward over time via a Downward Adjustment Factor (DAF) to align with national Net Zero trajectories. The framework includes detailed requirements for demonstrating additionality, accounting for embodied emissions from RES manufacturing, and managing reversal risks if the RES fails. A voluntary annex also allows for the quantification of avoided black carbon and PM2.5 emissions.

The document outlines the transition of the EU CBAM from a reporting-only phase to a mandatory financial compliance phase starting January 1, 2026. It details the obligations for 'Authorised CBAM Declarants', the calculation of embedded emissions using either actual verified data or punitive default values, and the requirement to purchase CBAM certificates linked to EU ETS prices. The guide emphasizes the competitive advantage for low-carbon producers and provides a three-stage implementation checklist for exporters to minimize costs and ensure market access to the EU.

The document outlines a framework for mobilizing capital to reduce methane emissions and flaring in the oil and gas sector. It details how to structure debt instruments—such as green, sustainable, and sustainability-linked bonds—to prioritize emission reduction projects. The guide provides a comprehensive list of eligible activities, a hierarchy for quantifying emissions, and specific KPI and Sustainability Performance Target (SPT) matrices. It emphasizes the role of National Oil Companies (NOCs) and provides safeguards against 'greenwashing,' including requirements for third-party verification and rigorous reporting standards.

The document outlines a comprehensive approach to reducing methane emissions from solid waste, which accounts for approximately 20% of global anthropogenic methane emissions. It proposes a policy matrix categorized into legislative/regulatory, market-based, voluntary, and information/education approaches, mapped across the integrated solid waste management (ISWM) chain. The guide emphasizes that limiting global warming to 1.5 degrees Celsius requires the global implementation of solutions across all three categories of the ISWM chain: waste prevention/minimization, source separation/treatment of organics, and improved landfill engineering. It provides detailed case studies from Colombia, Germany, India, Italy, Peru, the Republic of Korea, and the United States to illustrate how different policy combinations are applied based on national contexts.

The waste sector accounts for approximately 20% of global anthropogenic methane emissions, equivalent to 5.4 Gt CO2e annually. This guide proposes a policy matrix organized by the solid waste management (SWM) chain to help policymakers implement a combination of legislative, market-based, voluntary, and educational tools. Key strategies include waste prevention, organic waste diversion (composting and anaerobic digestion), and improved landfill engineering (gas capture and biocovers). The document emphasizes that meeting the 1.5 degrees Celsius warming limit requires a comprehensive approach across the entire SWM chain rather than isolated solutions. It provides case studies from Colombia, Germany, India, Italy, Perú, the Republic of Korea, and the United States to illustrate how different nations layer these policy tools to reduce emissions.

The guide also details various financing models, including Public-Private Partnerships (PPP), and stresses the importance of a two-level maintenance strategy and the appointment of an energy manager ('Monsieur/Madame Energie') to ensure long-term system viability.

The CoMAT Methodology guide details how the tool calculates methane emissions using a bottom-up equipment-based inventory combined with specific top-down measurements. It outlines the data inputs, emission factors, and abatement strategies for various oil and gas industry segments, including exploration, production, processing, transmission, storage, LNG, and distribution. The tool leverages defaults primarily from the US GHG Inventory (US GHGI) while allowing for country-specific updates to refine emissions inventories and design policy strategies.

The document analyzes the implementation of Article 6 of the Paris Agreement, focusing on the distinctions between the bilateral/multilateral trades of Article 6.2 and the UN-overseen global market of Article 6.4. It highlights critical loopholes, including the risk of double counting in aviation offsetting (CORSIA), the lack of oversight for Article 6.2 trades, and the potential for 'junk' credits from the Clean Development Mechanism (CDM) to transition into the new system. The author argues for stricter authorization processes, mandatory transparency, and a 'firewall' between carbon markets and the new climate finance package being negotiated at COP29.

The document defines carbon dioxide removal (CDR) as the physical extraction of CO2 from the atmosphere and its permanent storage. It argues that CDR must be a complement to, not a substitute for, aggressive emission reductions (over 90%). The guide evaluates six negative emissions technologies and practices (NETPs)—including Bio-CCS, DACCS, and biochar—while critiquing current EU policies for failing to distinguish between permanent removals and temporary biological sequestration. It advocates for a diversified portfolio of CDR methods, rigorous life-cycle accounting, and a governance framework based on the 'planetary boundaries' to avoid ecological trade-offs.

Thermal batteries can abate up to 99% of heat emissions in US chemical and refining plants by storing renewable electricity as heat in materials like graphite or bricks. These systems can provide heat up to 1800°C for reactions and distillation, with a levelized cost of heat between $20 and $87 per MWh. Integration involves assessing heating needs, retrofitting steam systems, and implementing automated charging based on electricity prices. While heat pumps are suitable for processes up to 200°C, thermal batteries address higher temperature needs. The guide advocates for policy reforms, including wholesale electricity rate access and permitting reform for non-adjacent parcels, to enhance the viability of industrial electrification.
