This policy brief argues that the current reliance on a single 100-year metric for greenhouse gas emissions obscures the distinct warming impacts of methane and carbon dioxide. The author advocates for a "multi-basket" approach with separate targets and dual metrics to address both short-term and long-term climate risks, asserting that simultaneous mitigation of both pollutants is essential to meet global temperature targets and reduce climate overshoot.

This RMI fact sheet introduces the Oil Climate Index plus Gas (OCI+), an interactive web tool designed to model the life-cycle emissions intensity of global oil and gas assets. The document argues that fossil fuel resources vary significantly in their climate footprints and emphasizes the need for high-quality public data and the use of a 20-year global warming potential (GWP20) to accurately assess the impact of methane emissions.

An assessment by Ember comparing government-reported coal mine methane (CMM) emissions to independent studies, finding that actual emissions may be up to twice as high as reported to the UNFCCC.

This briefing by RMI examines the debate over emissions accounting methods in New York State, specifically focusing on the shift to a 20-year global warming potential (GWP20) timeframe and the inclusion of upstream and biogenic emissions. The author argues that this 'new climate math' increases climate benefits without necessarily increasing costs, as physical emissions remain constant regardless of the accounting timeframe used.

This executive summary from the Canadian Association of Physicians for the Environment (CAPE) outlines the environmental and human health risks associated with hydraulic fracturing (fracking) for natural gas, specifically focusing on impacts in Canada and the United States. It argues that methane leaks undermine the role of natural gas as a bridge fuel and calls for a moratorium on new fracked gas wells in Canada.

This statement by RMI authors argues that a low-carbon, sustainable global energy economy is achievable through willpower and policy coordination, countering claims that renewable energy is too environmentally destructive or resource-intensive.

This fact sheet from the Environmental and Energy Study Institute explains the role of short-lived climate pollutants (SLCPs)—including black carbon, methane, tropospheric ozone, and hydrofluorocarbons (HFCs)—in global warming. It argues that while carbon dioxide (CO2) is the primary driver of long-term climate change, reducing SLCPs can provide rapid, short-term benefits to slow the rate of warming and improve public health and food security.

Ember's consultation response argues that Australia's Safeguard Mechanism must be significantly strengthened to address coal mine methane (CMM) emissions, which it claims are underestimated by 30-40%. The document advocates for a mandate against new coal mines, the adoption of a 20-year Global Warming Potential (GWP) for methane, and the implementation of strict industry benchmarks (1-3kg/tonne) to drive the closure of 'super-emitting' mines and the adoption of available capture technologies.

This guide describes the Effects screen within the LEAP software, which allows users to view, edit, and manage data for environmental effects such as pollutants and greenhouse gases (GHGs). It details the software's default data sets, the ability to customize effects, and the process for setting Global Warming Potential (GWP) values based on IPCC Assessment Reports.

This guide explains how to display and configure environmental results within the LEAP software, detailing the options for reporting individual effects, Global Warming Potential (GWP), and the territorial accounting approach used for emissions.

This WRI working paper provides a comprehensive analysis of global anthropogenic greenhouse gas (GHG) emissions for the year 2005, comparing them to data from 2000. It details the distribution of emissions by gas type and economic sector, highlighting the growth of emissions in developing countries and the impact of revised methodologies on land-use change estimates.

A data visualization of global greenhouse gas (GHG) emissions for the year 2000, detailing the percentage contributions of various sectors and specific activities based on a total global estimate of 41,755 MtCO2 equivalent.
