Due to the coronavirus crisis, it was difficult to estimate<br />
how <strong>Eawag</strong>’s energy balance had developed in<br />
2020 and 2021. Now it is clear that we have been able<br />
to improve. The total primary energy used in the building<br />
sector in <strong>2022</strong> was again at about the same level<br />
as in 2006 (approximately 3,600 MWh) – although the<br />
number of employees increased and the energy reference<br />
area grew from about 28,000 to 34,345 m 2 . The<br />
CO 2<br />
emissions fell from 1,640 to 256 tCO 2<br />
e in the same<br />
period. Net zero has not yet been achieved and more efforts<br />
are required to reach this objective. Likewise, the<br />
positive figures should not hide the fact that mobility<br />
(especially flying), procurement and catering cause considerable<br />
CO 2<br />
emissions, which have only been partially<br />
recorded so far. Another piece of the puzzle towards low<br />
CO 2<br />
mobility was laid in <strong>2022</strong> with the introduction of a<br />
PubliBike station on the Dübendorf campus.<br />
