From Elefsina Refinery Upgrade Overview


The completion, in previous years, of the two major modernization-upgrading projects at the Elefsina and Thessaloniki refineries, amounting to €1.7 billion,resulting in a significant improvement of the refineries’ environmental footprint and the air quality in neighbouring areas, constitutes a most favorable condition and starting point with which to harmonize with the new emission levels recently decided at a European level concerning refineries. The long-term environmental targets, in key priority areas for the Group and refineries (as main production activity), are as follows:

  • Reduction of tn CO2 emissions/ tn crude oil index by at least 5% though the next 5 years (refineries).
  • Reduction of Carbon Footprint by at least 250,000 tn CO2 investing in renewable energy (at least 100MW self-produced electricity) through the next 10 years.

Moreover, the Group, with the objective of continuous updating on the best environmental practices and the development of corporate culture, on environmental protection and management, firmly and consistently implements a number of activities concerning ongoing environmental education and awareness for its employees, customers, suppliers, subcontractors, public and local authorities, etc.
