The World Resources Institute (WRI) reported 'net' CO2 emissions of 1,031 metric tons in 2004 and 978 metric tons in 2005, representing a 3% and 8% decrease respectively from its 2000 base year. To achieve its 'net zero' goal, WRI utilizes a combination of internal efficiency measures, the purchase of renewable energy certificates (RECs), and investments in GHG offsets through the Chicago Climate Exchange. The organization also updated its accounting methodology to exclude paper emissions from its primary goal due to calculation uncertainties, though it continues to track them separately. Beyond its own footprint, WRI manages several multi-stakeholder partnerships, including the GHG Protocol and Climate Northeast, to promote corporate greenhouse gas management.

The document provides a framework for Brazilian livestock producers to issue certified green bonds aligned with the 1.5°C goal of the Paris Climate Agreement. It details a three-step issuance process—pre-issuance, issuance, and post-issuance—and defines eligible projects across three routes: whole production units, specific unit interventions, and supporting activities outside the farm. To achieve certification, issuers must meet specific screening indicators, including no land conversion since 2010 and demonstrated low-carbon animal management. The guide highlights Brazil's significant role as a global livestock producer and the potential for green bonds to reduce methane emissions, which account for nearly 65% of the country's agricultural emissions.

The STARRS pilot project, initiated by Climate Group and Climate TRACE, demonstrates how satellite imagery and artificial intelligence can provide timely, granular greenhouse gas (GHG) emissions data for subnational governments. By tracking six pilot regions—Abruzzo (Italy), Basque Country (Spain), Jalisco (Mexico), Querétaro (Mexico), Pernambuco (Brazil), and Western Cape (South Africa)—the project addressed common barriers to emissions accounting, such as high costs and long timeframes associated with traditional bottom-up methods. The project provided historical data from 2015 to 2021 across sectors including electricity, heavy industry, and road transport, while also mapping biomass changes. Findings for the pilot regions highlighted specific emission drivers, such as the dominance of the Bilbao Refinery in the Basque Country's oil and gas sector and the significant impact of feedlots in Jalisco and Western Cape.

Ember argues that Australia's 43% emission reduction target by 2030 is implausible without addressing coal mine methane (CMM), which dominates the energy sector's methane emissions. The submission urges Australia to join the Global Methane Pledge, improve its methane inventory to address potential underreporting, and adopt a 20-year emissions factor for domestic strategy to better reflect methane's short-term warming power.

The document provides technical instructions for displaying environmental results in LEAP, detailing the use of Global Warming Potential (GWP) factors based on IPCC reports and the four available reporting formats for GHG emissions.

It also explains specific data entry functions, such as the distinction between exogenous and endogenous capacity and the use of share versus saturation units in demand analysis.

The document argues that the existing UNFCCC monitoring system requires a significant retrofit and new processes to meet the more specific MRV obligations envisioned in the Bali Action Plan for a post-2012 agreement. It highlights that MRV is essential for the credibility and effectiveness of commitments regarding mitigation actions by developed and developing countries, as well as the associated technology, finance, and capacity-building support.

The Land Emissions and Removals Navigator (LEARN) is a free, interactive web tool designed to help U.S. cities, counties, and municipalities analyze the greenhouse gas (GHG) impacts of forests and trees at a community scale. Developed by the World Resources Institute, ICLEI, and partners, the tool provides automated spatial analysis to support data-driven planning and monitoring of nature-based solutions. It utilizes national datasets from the U.S. Forest Service and U.S. Geological Survey to estimate carbon emissions and removals resulting from land cover change, forest disturbances, and changes to tree canopy on non-forest lands. The tool is intended to complement ICLEI's U.S. Community Protocol’s Appendix J: Forests and Trees to assist local leaders in aligning their actions with state and national mitigation targets.

The report analyzes greenhouse gas (GHG) emissions for Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin. Utilizing the World Resources Institute's Climate Analysis Indicators Tool (CAIT-US), it examines all six Kyoto GHGs across the regional economy to overcome inconsistencies in previous state-level inventories. The analysis covers regional, sectoral, and state levels, assessing major emission sources, trends, and socioeconomic drivers to inform stakeholders on the Midwest's role in global climate change.

The document examines the distinct roles of national and corporate/facility GHG inventories, noting that they are often developed independently. It argues that integrating source-level data from facilities into national systems and sharing technical and institutional resources can enhance the quality of emissions data and strengthen mitigation strategies, particularly in resource-constrained environments.

The document defines GHG emissions registries as databases for tracking emissions from individual emitters, distinguishing them from top-down national inventories.
