Оцінка летучих викидів у газовій галузі України з врахуванням Уточнень 2019 р. до керівних принципів МГЕЗК 2006 р. з національних інвентаризацій парникових газів

Abstract

The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 to assess the risks and possible consequences of anthropogenic climate change. The IPCC includes a task force on national inventories, which develops methodological documents for national greenhouse gas inventories. The report 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. The development of 2019 Refinement is related to the improvement of existing and the emergence of new technologies in the world economy, which has led to the need to update emission parameters and take into account new sources of greenhouse gas emissions and removals. The purpose of the article is to study and apply changes in the methods of estimating fugitive emissions in Ukraine’s gas industry, taking into account 2019 Refinement to the 2006 IPCC Guidelines for national greenhouse gas inventories. The article examines the state of greenhouse gas emissions in the gas industry in 2019 according to the Ukraine’s Greenhouse Gas Inventory Report data. The formation methane and carbon dioxide fugitive emissions in the last National Inventory Report according to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories is analyzed. The changes in the methods for national inventories in the energy sector 2019 Refinement are compared to the 2006 IPCC Guidelines. The estimation methane and carbon dioxide fugitive emissions in Ukraine’s gas industry in 2019 according to 2019 Refinement is made (taking into account the new emission factors and a new subcategory of abandoned wells). The article provides a comparative analysis the results with fugitive emissions in the gas industry in 2019 according to data of National Inventory Report. A study of the results shows that the use of 2019 Refinement for future greenhouse gas inventories will reduce methane and carbon dioxide emissions.
