Climate Change and GHG emissions



Climate Change and GHG emissions

Greenhouse gas emissions concentrate in the atmosphere and form a layer that allows solar rays to penetrate but prevents the heat generated by them from dissipating, leading to the so-called greenhouse effect.

Minimization and Adaptation

Adaptation to climate change consists of anticipating the adverse impact of climate change and acting to prevent or minimise the damage these impacts may cause.


Aware of the potential impact of climate change on energy transmission and storage infrastructures, REN has been actively working to identify and implement measures to adapt and mitigate the consequences arising from the risk of extreme weather events that might affect its infrastructures.

Direct and indirect emissions

The atmospheric emissions related to REN's activity can be divided, in terms of their origin, as follows:

Reduction of emissions

In order to reduce and control greenhouse gas emissions, REN has been implementing over the past years an action plan to reduce direct emissions of such gases, in particular with regard to emissions of sulphur hexafluoride (SF6), a gas used as an electrical insulator (dielectric) in various high voltage equipment. To learn about best practices in handling this gas, REN attends international working groups where these issues are discussed.

REN also strives to minimise its environmental impact associated with greenhouse gas emissions by implementing different measures, in particular:

- Control of natural gas purges which occur along the gas network;

- Preventive maintenance of infrastructures, responsible for the largest amount of CO2 equivalent indirect emissions into the atmosphere and for the direct emission of SF6;

- Decrease in indirect emissions associated with Group employees' travel by arranging videoconferences whenever possible between the various facilities and international meetings;

- Promoting and incentivising train rather than light vehicle travel for work-related journeys.
