Climate action and energy efficiency

Improving energy efficiency and reducing greenhouse gas emissions are two aspects that will reinforce the key role that natural gas plays in creating a low-carbon economy, where energy is sustainable, safe and efficient.

At Enagás, we are committed to sustainability and, hence, have made a commitment to be a carbon-neutral company by 2040. As part of this commitment, we have a decarbonisation pathway based on specific energy efficiency and emission reduction measures, and the setting of interim emission reduction targets. 




Since 2014, we have reduced our Scope 1 and 2 emissions by 54%


These decarbonisation targets, which are set out in the company’s Energy Efficiency and Emissions Reduction Plan, are aligned with the 1.5ºC scenarios and have been set using science-based criteria. In addition, the company’s commitment to decarbonisation has been extended to all Enagás professionals, given that the emission reduction targets are linked to employees’ variable pay.


Our decarbonisation pathway

The company is currently working to achieve the following emission reduction targets:


Emission reduction targets Scope 1 and 2


Reduction targets compared to the company’s 2018 emissions:

  • Reduce Scope 1 and 2 emissions by 25% by 2024. This target is included in our 2022-2024 Long-Term Incentive Plan and linked to the variable pay of all the company’s professionals.
  • Reduce Scope 1 and 2 emissions by 50.4% by 2030.
  • Reduce Scope 1 and 2 emissions by 92.4% by 2040. 



Emission reduction targets Scope 3


Reduction targets compared to data recorded by the company in 2021:

  • Reduce Scope 3 emissions by 25% by 2030.
  • Reduce Scope 3 emissions by 50% by 2040.


Since 2014, we have reduced our Scope 1 and 2 emissions by 54%.

Scope 1 emissions arising from our activity come from the consumption of natural gas at our facilities, mainly at the compressor stations.

On the other hand, Scope 2 emissions are generated by electricity consumption. Given that Enagás has a 100% Renewable Energy Guarantee of Origin contract for all its facilities, the emissions associated with electricity consumption are zero.



Since 2015, we have reduced our methane footprint by 36%. Specifically, in 2021, methane emissions accounted for 23.5% of Enagás’ carbon footprint (Scope 1 and 2). 71% of these emissions came from venting during operation, maintenance and safety work or from analytical equipment, and the remaining 29% from uncontrolled and continuous gas leaks.



The company is implementing the following measures to minimise methane emissions from its activities:


In 2019, we joined the Global Methane Alliance initiative [SMN1] and committed to reduce our methane emissions by 45% by 2025 and by 60% by 2030 with respect to 2015 figures. The company also joined the Oil & Gas Methane Partnership (OGMP2.0) aimed at aligning companies’ methane emissions reporting with the European Methane Strategy, and obtained ‘Gold Standard’ recognition for its commitment to reduce emissions and data reliability improvement plan.


At Enagás, energy efficiency plays a key role in reducing emissions and, as such, we have made significant efforts to reduce the consumption of gas and electricity as part of our Energy Efficiency and Emissions Reduction Plan. In addition, we are ISO 50001 certified for energy efficiency.

In 2021, we increased the percentage of electricity with a Renewable Energy Guarantee of Origin to 100%. In addition, we continue our commitment to self-generation of electricity from efficient, clean and renewable sources. Indeed, in 2021 we increased self-generation by more than 45% compared to 2018 by implementing measures such as the use of waste energy from infrastructure processes to generate electricity.

In this area, special mention must be given to initiatives such as the use of waste heat at our Almendralejo compressor station, the use of waste cold from LNG at our Huelva regasification plant, and the use of pressure at the Barcelona regasification plant.

Furthermore, with the aim of being carbon-neutral in key strategic areas, in 2021, the company offset the emissions of all its regasification plants, Euskadour compressor station, the vehicle fleet and its headquarters.

We also support start-ups participating in our Corporate Venturing programme, Enagás Emprende, that offer innovative solutions for the utilisation of waste energy, such as E4Efficiency.


Scope 3 emissions correspond to our value chain. In this regard, after analysing the impact of gas transmitted throughout the value chain, the variables represented in the following diagram have been calculated.


(1) Includes emissions from the extraction and processing of LNG and transportation by tanker to the regasification plants. Emissions calculated based on the amount of LNG unloaded at regasification plants and based on the number of LNG tankers received..

(2) Includes emissions from the combustion of all gas 1) regasified; 2) loaded in trucks and 3) loaded in tankers at regasification plants.


As a result of this analysis, the company has updated and classified Scope 3 emissions, and takes a broader approach to its value chain.


In addition, the company is working on the following lines of action to achieve the reduction targets set for Scope 3 emissions:






Our carbon footprint is ISO 14064 certified and recorded in the Spanish Ministry for the Ecological Transition’s Carbon Footprint Register with the ‘Calculate, reduce and offset’ seal.

We are in CDP’s Climate Change ‘A List’, the highest ranking of this annual sustainability rating.


Our headquarters are LEED Gold certified as a sustainable building in terms of energy efficiency and environmental design.
