GHG Emission Trends and Targets (GETT) : Harmonised quantification methodology and indicators

The Paris Agreement maps out a path for internationally coordinated efforts to curb global warming. At the centre of the Paris Agreement are Nationally Determined Contributions (NDCs) that establish countries’ plans to mitigate greenhouse gas (GHG) emissions as well as adapt to the impacts of climate change. However, mitigation contributions defined in NDCs are different across countries in terms of target types, coverage of sectors and gases. This makes it challenging to assess progress on mitigation commitments. To complement the UNFCCC efforts, and facilitate the evaluation and monitoring of targets, this paper develops a methodology that harmonises countries’ 2030 mitigation targets in physical units and provide clarity on sector and gas coverage. The results are used to develop the GHG Emission Trends and Targets (GETT) indicators for non-EU countries and the EU-27 covered under the International Programme for Action on Climate (IPAC). The GETT indicators support the analyses of emissions' trajectories by describing historical GHG emission trends and comparing them to NDC emission targets, considering various reference years and indicators, including emissions intensity per capita or per unit of GDP.
