This year, the overall energy consumption decreased by 5%; the usage of gas and electricity was reduced by 9% and 4% respectively.

The change in energy consumption is influenced by the above stated changes in reporting scope, to UCB’s production volumes in general, to variations in climatological conditions (with an impact on the need for cooling and/or heating), to energy saving programs implemented at various UCB sites. The increase in the consumption of fuel is due to the fact that the Brazilian operations are included for the first time in the reporting scope.

Energy saving initiatives implemented in 2017 led to a recurrent energy saving of 7 135  GigaJoules, which is 0.9% of UCB’s scope 1 and scope 2 energy usage. Energy saving projects were completed at the sites in Bulle (Switzerland), Braine-l’Alleud (Belgium) and Saitama (Japan). Key contributors were an optimization of the Multicolumn Continuous Chromatography (MCC) equipment used at the chemical production plant in Bulle and energy efficiency gains in the distribution of fluids at the chemical production plant in Braine l’Alleud and in the microbial inactivation process at the bioplant in Bulle.

In 2017, 92% of the electricity consumed by UCB originated from renewable sources, with six UCB sites relying fully on  electricity generated from renewable sources, i.e., Bulle (Switzerland), Monheim (Germany), Atlanta (U.S.), Slough (U.K.) Braine-l’Alleud and Brussels (Belgium). Electricity sources include solar, wind and hydropower, as well as, biomass.

UCB generated 2 336 GigaJoules of electricity through solar panels installed in Braine-l’Alleud and Bulle, an increase of 52% compared to 2016 due to the installation of additional solar panels in Braine l’Alleud.

Overall scope 1 and scope 2 CO2 emissions were reduced by 17%; scope 1 emissions decreased by 5% while scope 2 emissions were reduced by 46%. These reductions are mainly due to the divestiture of the sites in Shannon in the second quarter of 2016, the revamping project that occurred at several manufacturing plants and the fact that 92% of consumed electricity is now generated from renewable sources.

Business travel, associated with scope 3 CO2 emissions resulted in 54 987 tons, an increase of 1% when compared to 2016.
