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 32%


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 2022 emissions:

  • Reduce Scope 1 and 2 emissions by 47% by 2026. This target linked to the variable pay of all the company’s professionals.
  • Reduce Scope 1 and 2 emissions by 61% by 2030
  • Reduce Scope 1 and 2 emissions by 94% by 2040

(1) Carbon neutrality will be achieved in 2040 with 23,162 tonnes of CO2e offset by nature-based solutions projects (reforestation).



Emission reduction targets Scope 3


Reduction targets* compared to data recorded by the company in 2022:

  • Reduce Scope 3 emissions by 42% by 2030
  • Reduce Scope 3 emissions by 61% by 2040


*Targets corresponding to 100% of indirect Scope 3 emissions, the most significant of which include emissions derived from natural gas flowing on and off our infrastructure network, emissions from our affiliates and our main suppliers (GHG Protocol categories 1, 2, 3, 4, 5, 6, 7, 9, 11, 15).





Since 2014, we have reduced our Scope 1 and 2 emissions by 32%.

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 30%. Specifically, in 2022, methane emissions accounted for 17.5% of Enagás’ carbon footprint (Scope 1 and 2). 76% of these emissions came from venting during operation, maintenance and safety work or from analytical equipment, and the remaining 24% from uncontrolled and continuous gas leaks. Regarding gas leaks, in 2022 they represented 0.010% and 0.019% of gas throughput for transportation and storage activities respectively.



We are implementing the following measures to minimise methane emissions from our 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.


In addition to its activity chain’s impact on emissions, Enagás includes the impact of the gas transported by the company in the natural gas value chain in its Scope 3 emissions. 


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


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.

Since 2021, we have the 100% of our electricity with a Renewable Energy Guarantee of Origin. In addition, we continue our commitment to self-generation of electricity from efficient, clean and renewable sources. Indeed, in 2022 we increased self-generation by more than 56% 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 2022, 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.


We ensure that our commitment to decarbonization is also reflected in the activities we carry out to contribute to the improvement and advancement of the European Union's legislative and regulatory framework, as well as in our lobbying activities and/or relationship with trade associations ensuring their alignment with the Paris Agreement. In this regard, these activities are carried out according to the following management system:

  1. Evaluation of the degree of alignment of the purpose of the initiative and/or association with that of Enagás. In this way, and prior to the development of an action or relationship with a partnership, we confirm that the purpose is aligned with our climate strategy and therefore with the decarbonization objectives of the European Union for 2030 and with the Paris Agreement to limit global warming to below 2ºC. In the event of identifying a misalignment between the two positions on climate change, this could lead to the termination of the activity support and/or the relationship with the trade association.
  2. Management of the partnership/organization in line with our stakeholder management model.
  3. Periodic reporting of information on activities and resources dedicated through registration in the European Transparency Register.

Responsibility for this management lies with the Directorate General for Energy Transition.

Within the group of associations and organizations aligned with the Paris Agreement where Enagás makes contributions, Hydrogen Europe, Gas for Climate and European Hydrogen Backbone stand out, among others. Likewise, our actions in these organizations are mainly aimed at contributing to ongoing European legislative and regulatory developments.







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.

Enagás has been listed in CDP’s Climate Change rankings since 2009. 


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