Reduction of GHG emissions

In 2019 as part of consistent reduction of GHG (CO2) emissions, KPO set a target to reduce direct GHG emissions by 280 thousand tonnes through implementation of a number of production optimization and energy efficiency projects.   

Thanks to implementation of the six projects listed in table below, the actual reduction of the GHG emissions exceeded the target almost twice. The reduction of GHG emissions (87%) was mainly achieved through the measures preventing the hydrocarbons flaring at wells.

Direct greenhouse gas emissions

KPO  direct greenhouse gas (GHG) emissions are regulated under the national quotas trading system in place. For 2018-2020 KPO obtained a quota on  GHG emissions based on the specific emissions` indicators (or benchmarks) for in the volume of 6,927,159 tonnes. In 2018 – 2019, total actual emissions amounted to 3,441,245 tonnes of CO2, which made 50% of the quota obtained.

The GHG emissions are accounted for carbon dioxide (СО2), methane (СН4) and nitrous oxide (N2O) using the calculation method on the basis of the Company’s operations data (in terms of fuel consumption and laboratory data on fuel composition).

According to the verified GHG Emissions Inventory Report for 2019, the total volume of GHG emissions amounted to 1,870,324tonnes in СО2-equivalent, of which, СО2 accounts for 1,710,330  tonnes of СО2-equivalent (91.4%), CH4 – 151,6532 tonnes of СО2-equivalent (8,1%), and N2O - 8,342 tonnes of СО2-equivalent (0.5%).

Information on the dynamics of generated GHG emissions is provided in table below. A slight decrease in GHG emissions (by 1.2%) in 2019 compared to 2018 was owing  to less consumption of fuel by stationary sources due to the total shutdown of the Field facilities (turnaround) in the reporting year.

Specific greenhouse gas emissions

In 2019, KPO specific GHG emissions amounted to 64 tonnes of СО2 per thousand tonnes of produced hydrocarbons, which is fully consistent with the target indicator on specific GHG emissions of no more than 67 tonnes of CO2 per thousand tonnes of hydrocarbon produced.

Graph below shows the dynamics of specific GHG emissions comparing to the specific emissions data provided by the International Association of Oil and Gas Producers (IOGP). The actual specific GHG emissions in KPO are lower than the European indicators by 23% and lower than the international indicators by 52%.
