Fighting climate change

Energy Transition and Decarbonization

REN’s activities seek to meet the energy policy objectives of the country and the European Union and, simultaneously, help the country and the planet combat climate change. REN guarantees the security and quality of the energy supply, increasingly sustained on renewable energy sources, while reducing its carbon footprint. 

Over the years, REN has carried out extensive work analysing the vulnerability to extreme climatic phenomena of electricity transmission and gas transmission and distribution infrastructures, reducing risks as regards security and quality of supply. 


Impact on infrastructure 

The worsening of the climate situation on the planet has put decarbonisation at the centre of public policies, in order to meet the targets for the reduction of greenhouse gas emissions.  


In the electricity sector the strong increase in renewable generation leads to the adaptation and development of transport infrastructures. in the gas sector this effort applies to the construction and adaptation of reception, storage, transmission, and distribution infrastructures for the incorporation of gases of renewable origin. 


A reinforcement in investment plans, fundamental to building and adapting electricity and gas networks to decarbonisation needs. 

The decarbonisation of electricity and gas energy systems is a crucial step towards a more sustainable future

Prevention of climate change

Greenhouse Gases (GHG) are gaseous substances naturally present in the atmosphere that absorb part of the infrared radiation emitted by the sun and reflected by the earth’s surface, hindering the release of this radiation (heat) into space. 
This natural phenomenon, called the Greenhouse Effect, hinders the loss of heat and allows the temperature on earth to remain within a range of values appropriate for the survival of living beings and ecosystems.

Sun light

Part of the solar energy is reflected by clouds and the Earth's surface.

These same gases, however, retain much of the heat generated by sunlight. This heat is reflected back to the surface by the molecules of the Greenhouse Gases, generating more heat.

As a result of human action, the concentration of these gases in the atmosphere is increasing, leading to an increase in the average global temperature.  

The main gases recognised by the Kyoto protocol as greenhouse gases are: Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), Sulphur Hexafluoride (SF6) and the Chlorofluorocarbon (CFC), Hydrofluorocarbon (HFC), and Perfluorocarbon (PFC) gas families. 

The first step for an organisation to contribute to combating climate change is to know its GHG inventory. Based on the inventory, the organisation can define strategies and targets for reduction and/or compensation. 

Direct and indirect emissions 

The emissions are classified according to the Greenhouse Gas Protocol (a joint venture between the World Resources Institute and the WBSCD - World Business Council for Sustainable Development) into: 

Scope 1 emissions

Direct emissions released into the atmosphere as a direct result of the company’s operations. An example are the gases produced from the burning of fuels, for mobility, industrial processes, heating of buildings, etc. Also included, in the case of REN, are emissions resulting from the loss of  methane, in gas infrastructures and sulphur hexafluoride, in electricity infrastructures. 

Scope 2 emissions

Indirect emissions, coming from the energy acquired for the company’s own use. Refers to all greenhouse gas emissions into the atmosphere from the consumption of electricity, steam, heating, and cooling. In the case of REN, emissions resulting from “losses” in the electricity transmission grid have a significant impact. 

Scope 3 emissions

These are all indirect emissions not included in scope 2 that occur in the company’s value chain. They are divided into 15 categories ranging from the purchase of products and services, to upstream transport and distribution, travel, treatment of sold products or investments, among others.
