Air quality

At Repsol, we are aware of the importance of protecting air quality, so we apply the latest technologies to minimize emissions from our production processes and work to supply society with increasingly sustainable products.

Air quality and climate change

It is important to differentiate between air quality, which is a local issue, and climate change, which is a global phenomenon. Air quality is principally affected by the local concentration of pollutants, produced by combustion processes and is determined by the energy mix, the size, and density of populations, meteorological conditions, etc. Air quality management is mainly conditioned by emissions of three elements: sulphur dioxide (SO₂), nitrogen oxides (NO_x), and particulate matter.

Minimizing emissions from our operations

At Repsol, we exhaustively monitor operating conditions to control air emissions from our activities. Atmospheric emissions are one of the main areas of work for the Company. Therefore, all our industrial facilities have a network of continuous measurement systems at the emission sources that allow us to continuously measure and analyze the composition and levels of our atmospheric emissions.

The data obtained is provided to the competent environmental authorities for monitoring and control. In addition to continuously measuring our emissions, we monitor air quality through emission booths located at strategic points and shared with administrations to ensure a quick response if a deterioration in air quality is observed. We are committed to reducing emissions from our operations by using the best available technologies (BAT), including the so-called disruptive technologies, and applying the highest standards to minimize our impact on air quality. We operate in regions, such as the European Union, where legal requirements in this sector require us to meet the most stringent targets. In countries where there is no regulation, we apply internal standards that allow us to operate with minimal impact.

Using clean fuels

We obtain the energy required for our processes from natural gas, which minimizes the generation of SO₂ and particulate matter in its combustion.

Cutting nitrogen oxides (NO_x) emissions

In energy generation activities, we reduce NO_x emissions by adopting new technologies and controlling operating conditions.

Reducing Volatile Organic Compounds (VOCs) emissions

Through vapor recovery actions and the use of leak detection and repair (LDAR) technologies.

Tarragona Observatory, beyond environmental control obligations

Air Quality Observatory of Camp de Tarragona was created as a response by Repsol and the Institut Cerdà to the concern detected in the territory about air quality by social and institutional agents. It was designed as a tool to measure, evaluate and publish data on emissions in the Camp de Tarragona, in particular on Volatile Organic Compounds. Today, it constitutes an initiative to go beyond the control obligations to which we companies are subject, by exercising responsibility, generating knowledge and transparency.

The objectives are focused on:

Enhancing the dissemination of the results and promoting public awareness of what VOCs are, how they are measured, and what is the context of air quality policy and sustainability.
Consolidating the Observatory as a permanent tool that contributes to the knowledge and debate on air quality.

Minimizing emissions from our products

At Repsol, we are committed to a model that integrates various technological options, that combines the use of renewable energies with the use of products with a low, zero, or even negative carbon footprint, and that offers solutions to all the society's needs.

LPG, an efficient energy solution

It offers sustainable and efficient solutions adapted to the needs of private and professional customers in two formats: bulk and packaged. Thanks to its low carbon footprint, high calorific value, and efficiency, Repsol LPG cares for air quality through clean combustion that provides lower NOx emissions and almost zero emissions of volatile compounds and carbon particulate matter.

Blue+, Repsol's Adblue

We market AdBlue® under our Blue+ brand, with hundreds of points of sale. AdBlue is a urea solution that reacts with the exhaust gases of diesel vehicles with SCR (Selective Catalytic Reduction) technology and converts nitrogen oxides into compounds that are harmless to the atmosphere and the environment (nitrogen and water vapour).
