Greenhouse gas and air pollutant emissions

Policy to reduce greenhouse gas and air pollutant emissions GRI 103–2, GRI 103–3, TCFD

The assessment of greenhouse gas emissions and harmful emissions into the atmosphere is an integral part of the industrial environmental control system for atmospheric air and is carried out on an annual basis for all the Group’s generating facilities.

The data on greenhouse gas emissions contained in the 2018–2020 Annual Reports was certified by an international auditor in accordance with International Standard 3410 ‘Assurance Engagements on Greenhouse Gas Statements’ issued by the International Auditing and Assurance Standards Board, and the relevant opinions on this were obtainedSee more on the website.

The Inter RAO Development Strategy until 2025 with a View to 2030, which was approved in 2020, states that reducing specific CO2 emissions by 7% versus the 2019 level is a strategic goal. In addition, the new Strategy stipulates the need to introduce mechanisms to analyze and assess climate risks as well as conduct inventories of greenhouse gas emissions and reduce them.

Greenhouse gas emissions GRI 305–1, GRI 305–4, TCFD

Greenhouse gasesThis only includes carbon dioxide emissions. This is due to the insignificant emissions of other greenhouse gases. are measured in accordance with the Guidelines and Manual for the Quantification of Greenhouse Gas Emissions by Organizations Operating in Russia, which was approved by Order No. 300 of the Russian Ministry of Natural Resources dated June 30, 2015.

Thanks to a wide range of measures, Inter RAO has reduced direct greenhouse gas emissions by 44% compared with the 2014 level (adopted as the baseline) and 22% versus the 2018 level. The Group’s gross greenhouse gas emissions amounted to 64.783 thousand tons in 2020. Specific greenhouse gas emissions amounted to 427 g of CO2/kWh in 2020, down by 4% compared with 2019.

Total SF6 gas emissions for all heat and power generating facilities amounted to 271.4 kg of SF6 in 2020.

Main reasons for the decrease in greenhouse gas emissions:

  • An economically justified increase in the share of medium- and high-power condensing and cogeneration CCGTs and gas turbines in the structure of gas generating capacities (including with the use of Russian gas turbine engines) with energy efficiency (efficiency rate or specific fuel consumption) and environmental safety indicators (specific emissions) at the level of the best world analogs
  • Enhanced energy efficiency of equipment as part of the Energy Conservation and Efficiency Improvement Program
  • Sale of the coal-fired Ekibastuzskaya TPP-2 with installed capacity of 1,000 MW in December 2019.
7% A reduction in specific CO2 emissions versus the 2019 level is documented as a strategic goal

KPIs for climate risks and opportunities

One KPI that is relevant for all employees and carries a weight of 20% is the Integral Innovation Index Fulfillment KPI, which was created to assess innovative activities and, among other things, envisages the implementation of an innovative development program in which one of the objectives is to reduce specific greenhouse gas emissions per unit of electricity generated.

Air pollutant emissions GRI 305–7

As a whole, the level of various pollutant emissions decreased compared with 2019. NOx emissions declined by 22% to 94,000 tons in 2020, while the level of SOx emissions fell by 38% to 85,000 tons. There has been a positive trend overall in greater fuel efficiency. Decreased production of electricity and coal-fired heat was the main factor in the reduction of specific air pollutant emissions.

The mass of pollutant emissions has also declined due to the systematic implementation of the Energy Conservation and Energy Efficiency Improvement Program. A 42% reduction in solid emissions in 2020 resulted from the Ekibastuzskaya TPP-2 leaving the Group as well as such activities as the routine maintenance of dust extraction plants.
