This year, the overall energy consumption decreased by 25%; usage of gas and electricity was reduced by 26% and 24% respectively, and usage of fuel increased by 5%.
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.
Energy saving initiatives implemented in 2016 led to a recurrent energy saving of 7 492 GigaJoules, which is 0.9 % of UCB’s scope-1 and scope-2 energy usages. Energy saving projects were completed at the sites in Bulle (Switzerland), Braine-l’Alleud (Belgium) and Zhuhai (China). Key contributors were the installation of a heat recovery unit on steam condensation and the optimization of HVAC installations in Braine-l’Alleud and the completion of a project allowing to recover heat on process air compressors in Bulle.
In 2016, 80% of the electricity consumed by UCB originated from renewable sources with four UCB sites relying fully on green electricity, i.e., Bulle (Switzerland), Monheim (Germany), Braine-l’Alleud and Brussels (Belgium).
UCB generated 1 537 GigaJoules of electricity through solar panels installed in Braine-l’Alleud and Bulle.
Overall scope-1 and scope-2 CO2-emissions were reduced by 40%; scope-1 emissions decreased by 24% while scope-2 emissions were reduced by 60%. These reductions are mainly due to the divestiture of the sites in Seymour and Shannon. The impact therefore upon the scope-2 emissions was even strengthened by the fact that the sites in Seymour and Shannon still relied on electricity mainly generated from non-renewable sources.
Business travel, associated with scope-3 CO2-emissions resulted in 54 651 tons, an increase of 17% when compared to 2015.
