In 2023, direct greenhouse gas emissions are estimated at 156,000 tonnes of CO2‑eq., down 25% year‑on‑year.
Quantified greenhouse gas emissions include carbon dioxide (CO2), methane (CH4) and nitrogen oxides (N2O).
In 2023, the Climate Policy of PJSC Rosseti was adopted. The document identifies climate risks that are significant for the Company, mechanisms for influencing them, and measures to adapt to climate change.

PJSC Rosseti identifies two groups of physical climate risks: extreme weather events and irreversible climate processes.
For the risks associated with extreme weather events, a number of adaptation measures have been elaborated and are being implemented on an ongoing basis.
Climate risks
Examples of adaptation measures
Extremely high/low air temperatures
Revision of regulations to improve the reliability of power transmission lines (PTL) and transformer substations
Measures to maintain design temperature profiles of industrial build‑ings
Changes in tempera‑ture/humidity profile and precipitation condi‑tions; permafrost deg‑radation
Monitoring of soil conditions where the Company’s production facilities are located in the permafrost zone
Monitoring of the condition of buildings’ foundations and roofs
Installation of erosion control systems to maintain the permafrost con‑dition of the foundations of structures, buildings, and overhead trans‑mission lines
Floods
Identification of (under)flooding zones and prohibition of use of such zones
Engineering protection of grid facilities (dams, diversion channels, hy‑draulic obstacles)
Bank protection structures, bank reinforcement, dredging
Hurricanes, tornadoes, hail, very strong winds, glaze‑ice and rime phe‑nomena
Dismantling or replacement of obsolete or frail buildings and struc‑tures, and PTL towers
Cutting down old and rotten trees
Reinforcement of industrial buildings
Determination of safe operating modes in high‑wind conditions
Reinforcement of linear structures and monitoring the icing of the same
Training of emergency repair teams
Mudflows, water‑snow flows and landslides
Adjustment of surface water runoff through vertical planning of the territory and arrangement of surface drainage system
Agroforestry, artificial alternation of slope relief
Arrangement of anti‑mudflow systems, confining facilities and struc‑tures
Establishment of protection zones
In addition, the Group carries out the following routine general activities aimed:
To improve hydrometeorological monitoring and forecasting systems
To update and revise wind and ice load standards in order to enhance the reliability of power grid facilities
Undertake operational analysis of short‑term weather forecasts and storm warnings of dangerous meteorological phenomena
To develop local regulations for each special period, taking into account retrospective analysis
To furnish the subdivisions, which are most exposed to unfriendly weather conditions, with emergency equipment, including reserve power supply sources and off‑road special vehicles
To run cooperation exercise in responding to emergency damage to power grid facilities
