2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers; Special Report on Climate Change and Cities; Global Warming of 1.5°C; Climate Change and Land; 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories; The Ocean and Cryosphere in a Changing Climate

The 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories was adopted and accepted during the 49th Session of the IPCC in May 2019. It was prepared by the Task Force on National Greenhouse Gas Inventories (TFI) in accordance with the decision taken at the 44th Session of IPCC in Bangkok, Thailand, in October 2016.

IPCC assessments and special reports are prepared by three Working Groups, each looking at a different aspect of the science related to climate change: Working Group I (The Physical Science Basis), Working Group II (Impacts, Adaptation and Vulnerability), and Working Group III (Mitigation of Climate Change).

The IPCC has completed assessment reports, developed methodology guidelines for national greenhouse gas inventories, special reports and technical papers. For more information on the IPCC, its activities and publications, please see the IPCC homepage .

This document provides 100-year time horizon global warming potential (GWP) values from the Intergovernmental Panel on Climate Change (IPCC). The table below is adapted from the IPCC Sixth Assessment Report, 2020 (AR6).i.

Intergovernmental Panel on Climate Change (IPCC) Summary text Library of emission factors and other parameters with background documentation or technical references

Help countries estimate and report GHG emissions reliably. Provide methods and tools for consistently compiling GHG inventories. The guidelines don’t assess the potential of emission reduction measures or mitigation strategies. • Used by compilers to create GHG inventories for international reporting (e.g., to the UNFCCC).

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for the assessment of climate change. The IPCC reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of …

Several components of the climate system, notably the oceans and living things, affect atmospheric concentrations of greenhouse gases. A prime example of this is plants taking CO 2 out of the atmosphere and converting it (and water) into carbohydrates via photosynthesis.

The overall IPCC approach to greenhouse gas emissions from combustion of biomass or biomass-based products (e.g., ethanol) at the national level allows for complete coverage of emissions and removals, and involves all IPCC sectors, including in particular, Energy, AFOLU, and Waste (see e.g. Volume 2, Chapter 2, Section 2.3.3.4; Volume 3, Chapter...
