Air quality and atmospheric emissions

Galp promotes the efficient use of energy and select a fuel portfolio to minimise atmospheric emissions.

Aware of the importance of air quality to public health and the environment, protecting it is already integrated in our operations management.

To ensure our operations and our products are more sustainable, we have implemented the best available technologies (BAT) to reduce atmospheric emissions by:

  • optimising combustion systems;
  • adjusting the fuel portfolio;
  • introducing nitrogen oxide reducing additives to the Fluid Catalytic Cracking (FCC) unit;
  • incorporating new fuel specifications to minimise the environmental impact caused by the use of marketed products;
  • establishing goals and targets based on performance KPIs.

We monitor our atmospheric emissions from both fixed and mobile sources and ensure that our performance is verified by an independent third-party.

Gas in energy production

We practice sustainable management of the fuel portfolio in all our operations. Gas is the main fuel used in energy production.

Emission reduction

In 2017, we achieved significant reductions in the atmospheric emissions from our refining units compared to 2006:

-76% -71% -85%
of NOX emissions of SO2 emissions of particulate emissions

Reduction of carbon intensity in refining (CO2/CWT)

Sines Refinery 2013/17 Matosinhos Refinery 2013/17
-17% -15%

We set ambitous targets in line with the eco-efficiency goals established for our operations. Our objective is to promote the continuous improvement of the environmental performance of our operations.

The definition of less ambitious targets, where applicable, is related to stoppages or maintenance in the units of our refineries.
