Within IPCC the National Greenhouse Gas Inventory Program develops methodologies to estimate emissions of greenhouse gases This has been undertaken since 1991 by the IPCC WGI in close collaboration with the Organisation for Economic Cooperation and Development and the International Energy AgencyA greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect The primary greenhouse gases in Earth's atmosphere are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and ozone (O 3)Without greenhouse gases, the average temperature of Earth's surface wouldIn order to ensure precision and reliability, national GHG inventories are required to fulfil certain criteria, as laid out in the IPCC Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories (hereinafter referred to as the IPCC good practice guidance)6 Thus, the inventories must be

Greenhouse gases (GHGs) are a group of substances that contribute to global warming They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulphur hexafluoride (SF6), perfluorocarbons (PFCs) hydrofluorocarbons (HFCs) and many other compounds listed by the IPCC* The 100year GlobalIn discussions on climate change, we tend to focus on carbon dioxide (CO 2) – the most dominant greenhouse gas produced by the burning of fossil fuels, industrial production, and land use changeWe cover CO 2 – global emissions, annual, cumulative, per capita, and consumptionbased emissions – in great detail in our CO 2 emissions page But CO 2 is not the only greenhouse gasThe IPCC Special Report on Aviation demonstrates that the total impact of a sector is not represented by (nor scalable to) the direct emissions of primary greenhouse gases alone, but needs to consider a wide range of atmospheric changes
