Environmental benchmarking

Environmental benchmarking is a tool for assessing and managing the environmental efficiency of Samruk-Energy JSC by comparing its own indicators with the results of leading companies in the industry. This approach promotes the introduction of the best international practices in the field of environmental management and sustainable development. The current analysis uses publicly available data for 2021–2023. After the publication of environmental indicators for 2024, the benchmarking will be updated and its results will be posted on the Company's official website.

The following indicators are defined for benchmarking:

  • utilisation of fresh water for technological and domestic needs;
  • direct (Scope 1) and indirect (Scope 2) greenhouse gas emissions.

To determine the environmental trend, the largest companies in the energy industry in Kazakhstan and the world were analysed, namely:

  • Enel;
  • ERG;
  • RusHydro PJSC.

The companies differ in terms of installed capacity and the volume of electricity generated, so the comparative analysis of specific indicators of greenhouse gas emissions and fresh water intake is tentative.

According to the obtained results, Samruk-Energy JSC has the following tendency:

  • specific GHG emissions in 2023 remained at the level of 2022 without significant changes, similarly to ERG and RusHydro PJSC. At the same time, Enel demonstrates an annual decrease of the indicator: by 3.6% in 2022 and by 25.9% in 2023;
  • the average specific water withdrawal for 2021–2023 was 6.22 m3/thousand kWh, which:
    • 20 times higher compared to Enel (0.31 m3/thousand kWh);
    • is 26.4% higher than that of RusHydro PJSC (4.92 m3/thousand kWh);
    • 16.6 times lower than ERG (103 m3/thousand kWh).

Based on the results of the analysis, Samruk-Energy JSC confirms its commitment to the sustainable development course. We will continue systematic work on carbon footprint reduction, introduction of modern technologies and solutions aimed at reducing greenhouse gas emissions. Modernisation of main and auxiliary equipment remains an important priority, which will improve resource efficiency and reduce water intake for technological needs of our subsidiaries.
