Another key aspect for Enagás in the environmental dimension is the management of natural capital and biodiversity. In this area, we analyse the dependencies and impact of our activity on natural capital in order to identify actions to minimise our environmental impact.
Below you can see the environmental impacts identified by the company, according to their significance and origin, and the main actions we carry out to prevent and reduce them.

Specifically, we conduct a natural capital assessment based on an environmental materiality analysis at the infrastructure level. In certain cases, we also carry out detailed assessments of the ecosystem services of the environment.
Enagás is a member of the Natural Capital Factory, a regional platform of the Natural Capital Coalition that brings together the Spanish community around natural capital approaches with the aim of ensuring that nature is included in decision-making.
We have set a target of no net loss of nature and biodiversity in 2040 and target of positive net impact in 2050, in both our greenfield construction projects and the existing infrastructure we operate. In addition, we have set the target of no net deforestation in 2040.
To this end, we carry out annual environmental assessments of the infrastructure in operation and Environmental Impact Assessments (EIA) for new construction projects, in accordance with the applicable typology and regulations. EIAs are public information and are subject to consultation processes with stakeholders. You can see the latest EIAs approved at the bottom of this page.
We have develop corporate biodiversity guidelines based on the impact mitigation hierarchy and aimed at preserving ecosystems and their biodiversity in our activities and areas of operation.
Our actions in the field of biodiversity aim to fulfil the following targets:
En la fase de diseño y planificación de los proyectos de construcción, siempre que sea posible, seguimos los corredores de otras infraestructuras ya existentes o utilizamos anchos de pista reducidos para evitar zonas de vegetación natural o hábitats potenciales de especies prioritarias.
Contamos con programas de vigilancia ambiental, que incluyen actuaciones como la reducción de los niveles de ruido y emisiones atmosféricas tanto en fase de obra como en operación aplicando las mejores técnicas disponibles.
Llevamos a cabo labores de restauración del suelo mediante la descompactación y reposición de tierra vegetal, la revegetación a través de la siembra de especies compatibles con el entorno o los programas de recuperación de especies.
Compensamos una parte de nuestras emisiones a través de la inversión en proyectos de reforestación, contribuyendo a evitar cambios en las condiciones físicas de los ecosistemas en los que se desarrollan especies vegetales y animales.
In addition, we collaborate with external stakeholders (environmental engineering and consulting firms, local communities, public authorities and town councils where Enagás is present, NGOs, and biodiversity associations and foundations, etc.) to ensure compliance with the commitments set out in our corporate guidelines.
Our facilities occupy an area of 6.7 km2 of protected natural areas (Natura 2000 Network, CIS/SAC), Ramsar wetlands and Biosphere Reserve.
Consult the documentation on the EIAs for the main projects we are developing.
We promote the development of renewable gases as new key solutions in the decarbonization process and in the development of a circular economy.
Most of the waste generated by Enagás is related to the maintenance of facilities and equipment, and is mostly liquid waste.. In 2021, we obtained AENOR Zero Waste certification*, which recognises the company’s progress in maximising the volume of waste recycled or recovered, and in minimising the waste generated. In this sense, we aim to treat (recycle/recover) at least 90% of hazardous and non-hazardous waste. In addition, we have an action plan to increase the percentage of waste recovery in infrastructure and minimise waste generation.
Enagás has signed the Pact for the Circular Economy promoted by the Spanish Government. Under the Pact, we commit to promoting the transition to a circular economy through different actions on which we are already working.
* The Barcelona plant is outside the scope due to the incident with sanitary water..
At Enagás, we have a number of measures in place to reduce emissions from our activity that have an impact on the atmosphere. During the combustion of natural gas in the equipment of our facilities, non-greenhouse gases such as CO, SOx, NOx, PM10 particles and Non-Methane Volatile Organic Compounds (NMVOCs) are emitted. Therefore, these emissions are directly related to CO2 emissions and are affected by the energy efficiency measures and CO2 emission reduction targets. In 2021, there was an increase in non-greenhouse gas emissions compared to 2020, which was directly related to the increase in CO2.
In addition, we carry out regular environmental noise measurements at the perimeter of all our infrastructure to check that the levels are within the limits set by the applicable legislation. If deviations are detected, corrective actions are taken (acoustic screens, silencers, insulation, etc.).
In terms of light pollution, we work to reduce night lighting in our facilities by keeping perimeter lighting to a minimum or turning off the lighting at night.
Enagás does not use water in its production processes. Our main water intake is seawater for use in vaporisers and regasification plants. At the end of the process, it is returned to the sea in the same state; the decrease in temperature is minimal and does not affect the marine ecosystem. In 2021, 217.2 Hm3 of seawater was extracted and returned to its source.
Enagás does not use raw materials in its production processes, but rather auxiliary substances for transmission activities such as THT, methanol, oils, triethylene glycol and liquid nitrogen.
