The document analyzes the transition from project-based mechanisms like the Clean Development Mechanism (CDM) to sectoral-scale mechanisms. It evaluates three governance models for a Sectoral Crediting Mechanism (SCM): centralized (UN-led), hybrid (bilateral with UN minimum standards), and decentralized (independent of the UN). The authors argue that while decentralized models offer flexibility, they risk undermining environmental integrity and market credibility. The paper proposes a centralized SCM project cycle that improves upon the CDM by introducing more interactive baseline reviews, professionalizing the regulatory body, and utilizing biennial update reports for better verification.

The document serves as a resource for First Nations in Canada to navigate the economic opportunities and risks of carbon markets. It emphasizes that while global literature on indigenous peoples and carbon markets exists, there is a significant information void specifically regarding First Nations in Canada. The report argues that for indigenous participation to be equitable, governments must recognize carbon rights, obtain free, prior and informed consent, and adopt decentralized governance models that prioritize local employment over simple financial compensation. It also highlights the technical necessity of accurate carbon accounting, particularly in the boreal forest, where factors like insect infestations and soil moisture significantly impact carbon stock measurements.

The report argues that carbon trading is an ineffective and often corrupt mechanism for addressing climate change in Africa. It examines the Clean Development Mechanism (CDM) and voluntary markets, finding that they frequently favor large industrial polluters over sustainable development and marginalize local communities. Through case studies in South Africa, Uganda, and Ethiopia, the authors illustrate how 'additionality' is often fabricated and how projects can lead to land grabs or the subsidization of fossil fuel expansion. The document concludes that the carbon market is structurally flawed and should be abolished in favor of direct public funding and low-carbon development pathways based on historical responsibility.

The document examines the risk of 'double-counting' international greenhouse gas offsets, where both the buyer (developed country) and seller (developing country) count the same emission reduction toward their respective pledges. The authors argue that such accounting could dilute global climate ambition by up to 1.6 billion tons CO2e by 2020, potentially undermining the 2°C warming pathway. The brief analyzes different supply and demand scenarios and proposes policy remedies, such as buyer-only counting, credit-sharing, or the use of an international transaction log to ensure environmental integrity.

The report outlines how tropical forests can be transitioned from net carbon emitters to net sinks through the REDD+ framework. It details specific reforestation, restoration, and sustainable production forestry techniques, while emphasizing the necessity of 'additional' carbon benefits beyond business-as-usual baselines. The authors argue that achieving zero net emissions by 2030 requires a combination of reducing deforestation and scaling up sequestration activities, supported by international financial incentives and national policies that protect biodiversity and the rights of indigenous and local communities.

The document argues that the lack of harmonized accounting rules for Annex I pledges in the Copenhagen Accord creates uncertainty regarding the actual level of climate ambition. It recommends that the Conference of the Parties (COP) mandate the development of consistent, transparent, and accurate measurement, reporting, and verification (MRV) guidelines. Specifically, it addresses the need for standardized coverage of greenhouse gases and sectors, rules for land use, land-use change, and forestry (LULUCF), the prevention of double counting in international offsets, and the management of surplus assigned amount units (AAUs) from the Kyoto Protocol's first commitment period.

The review concludes that the Manomet study likely underestimates the net carbon emissions of biomass energy due to overly optimistic assumptions regarding forest regrowth, soil carbon, and fuel sourcing. While the Manomet study suggests utility-scale biomass emissions are higher than coal and natural gas, the review argues that the perceived benefits for small-scale thermal and CHP plants are likely illusory. Key criticisms include the model's reliance on harvesting large trees to maximize regrowth, the omission of soil carbon losses, and the failure to account for indirect land-use effects such as firewood leakage.

The paper examines the complexity of comparing national emissions pledges due to inconsistent base years, varying scopes of greenhouse gases, and divergent accounting methods for LULUCF. It analyzes the specific pledges of Annex I countries (Australia, Canada, EU, Japan, Russia, Kazakhstan) and non-Annex I countries (China, India), highlighting how 'cherry picking' accounting systems can make targets appear more ambitious than they are. The authors recommend a common accounting framework where countries provide scenarios showing how energy-related emissions, LULUCF, and international offsets contribute to their total commitments.

The report analyzes the environmental and social footprints of China's rapid economic growth within three specific sectors: forestry, cotton, and E-products. It argues that because China is a central 'middleman' in global supply chains, it shares responsibility with international partners to address degradation. For forestry, the report highlights China's role as a major importer of illegally logged timber and recommends building capacity in supplying countries and adopting sustainable procurement. In the cotton sector, it notes high water and pesticide use in domestic production and suggests promoting sustainable sourcing and Sino-African cooperation. For E-products, it focuses on the crisis of E-waste and the toxicity of informal recycling, recommending a national E-waste strategy and international cooperation on responsible disposal. The overarching strategy emphasizes national capacity building, leveraging sustainable markets through green procurement, and active participation in international sustainability standards.

The report analyzes the landscape of carbon offsets, contrasting mandatory compliance mechanisms like the Clean Development Mechanism (CDM) and Joint Implementation (JI) with voluntary standards and retail providers. It evaluates key design elements including project eligibility, additionality testing, and quantification protocols, while highlighting risks to environmental integrity such as leakage and non-permanence.

The working paper by the Graz Group outlines strategies to enhance the environmental integrity and completeness of LULUCF accounting. It suggests moving toward 'fuller accounting' through activities-based, emissions/removals-based, or land-use-based approaches. Key recommendations include mandatory accounting for forest and peatland degradation, a 'restricted stock-change approach' for harvested wood products to prevent false credits, and policy-based methods for 'factoring out' natural disturbances. The authors argue that current Kyoto Protocol rules allow significant emissions from degradation to go uncounted, particularly in Annex I countries that did not elect Article 3.4.

The report analyzes the global commodity chain of forest products where China acts as the central processing hub, importing raw materials from developing nations and exporting finished goods to Western markets. It highlights a systemic failure in governance and sustainability, particularly in Mozambique and Russia, where weak tenure rights and corruption lead to illegal logging and forest degradation. Conversely, it notes that trade with New Zealand demonstrates a positive model where strong governance ensures sustainable plantation management. The document argues that China's own self-interest—specifically the need for secure, long-term fibre supply—should drive it to lead international efforts in sustainable forest management, improve its procurement policies, and support capacity-building in supplier countries.

This research paper evaluates three prominent air travel emissions calculators, focusing on their handling of aircraft models, flight profiles, cargo, occupancy rates, and seat classes. The authors find that results vary significantly, with economy seat emissions differing by a factor of 1.7 between calculators. TRX Travel Analytics is rated as the highest quality due to its use of extensive, regularly updated datasets and carrier-specific information. The paper highlights that while specificity in aircraft models and seat classes can improve accuracy, uncertainties regarding engine types, maintenance, and actual flight behavior remain challenges for all tools.

The document outlines three primary methods for companies to obtain green power: retail green power programs, renewable energy certificates (RECs), and on-site generation. It provides a business case for the transition, focusing on GHG reduction, stakeholder relations, and cost stability. The guide also details procurement strategies to minimize premiums, such as energy efficiency upgrades and demand aggregation, and explains the methodology for accounting for carbon benefits in corporate GHG inventories using e-GRID emission factors.

The document examines BECCS as a tool for carbon dioxide removal (CDR) and energy production, detailing the interactions between biomass feedstocks, conversion technologies, and system outputs. It highlights the potential for BECCS to mitigate emissions from forest thinnings and agrifood wastes, while warning against land-use changes that compromise carbon sinks. The authors emphasize that BECCS cannot be categorically labeled as beneficial or detrimental, as lifecycle impacts vary based on the supply chain and technology used.

The Clean Air Task Force (CATF) is leading a project to reform the incentive and reward ecosystem for carbon-free energy (CFE) procurement. The initiative aims to move beyond limited renewable energy standards toward metrics that accurately reflect carbon impact, targeting the buying power of corporations, governments, and utilities. Key activities include updating GHG accounting standards, supporting pilot transactions, and helping federal agencies implement Executive Order 14057 to achieve 50% 24/7 CFE by 2030.

The Clean Air Task Force (CATF) argues that the EU must adopt a diversified, options-based climate strategy to reach its 2050 net-zero goal, as relying on a single pathway increases risk. The document emphasizes the necessity of carbon capture and storage (CCS) and carbon dioxide removal (CDR) technologies, noting that no operational CO2 storage sites currently exist in the EU. CATF recommends a portfolio of zero-carbon fuels, nuclear fission, fusion, and superhot rock energy to ensure energy security and a reliable 24/7 carbon-free electricity grid. It specifically proposes separate targets for greenhouse gas emissions reductions, nature-based removals, and industrial removals to ensure transparency and durability. Additionally, the document advises against including methane in the EU Emissions Trading System (EU ETS) to avoid disincentivizing CO2 reductions, suggesting instead separate initiatives like an EU Import Standard for oil and gas.

The authors argue that the current RED III methodology over-credits manure-based biomethane by using unrealistic baseline assumptions for manure management and incorrectly treating manure as a zero-emission waste feedstock. They call for a revision of the default avoided-emissions credit and a reassessment of system boundaries to include upstream livestock emissions.

The guidance outlines the application of GHG accounting within the real estate sector, specifically focusing on Scope 3 (value chain) emissions. It adapts the GHG Protocol's 15 categories to the building and construction system, identifying intended users—such as property developers, asset managers, and architecture firms—and mapping their reporting responsibilities across different life cycle stages of a building project.

A coalition of individuals and organizations argues that a clear, implementable model for funding beyond value-chain climate action already exists to support the global transition to net zero emissions. The proposed framework requires companies to prioritize their own decarbonization along a 1.5C° trajectory and follow five specific steps: calculating and disclosing GHG footprints (scopes 1, 2, and 3), determining a dedicated budget, conducting due diligence for a high-impact portfolio, financing those initiatives, and maintaining public transparency by separating these funds from internal efforts.
