THE REFINEMENT TO THE 2006 IPCC GUIDELINES FOR NATIONAL GREENHOUSE GAS INVENTORIES

Abstract

. In May 2019, the 49 th session of the Intergovernmental Panel on Climate Change (IPCC) adopted a methodological report entitled 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. In the document, the general methodological approaches used for the calculations of greenhouse gases emissions remained unchanged. The improvements mainly relate to the refinement and update of emission data and parameters for existing categories of sources and sinks, as necessary, as well as to the development of estimation methodologies for emissions from new, previously unrecorded, anthropogenic activities. The refinements proposed will improve quality and reliability of national greenhouse gases inventories. The introduction of new estimation methodologies enhances completeness and coverage of human-induced greenhouse gas emissions. However, the implementations of the proposed improvements will modify emission estimates from specific categories and sectors of anthropogenic activity, as well as the national inventory totals as a whole.
