Decreasing Energy Demand Despite Rising Number of Students

In 2024, UZH’s energy demand was prima­rily covered through elec­tri­city and dis­trict heating. In a long-term com­pa­rison, a de­coup­ling between UZH’s num­ber of stu­dents and its ener­gy de­mand be­comes ap­pa­rent: since 1980, the num­ber of stu­dents has in­creased signi­fi­cantly more than the energy de­mand. Be­tween 2020 and 2024, the energy de­mand de­creased des­pite the ri­sing num­ber of stu­dents. Fur­ther re­le­vant fi­gures re­gar­ding UZH’s sus­tai­na­bi­lity can be found in the inter­active diagrams.

At the time of the edi­torial dead­line for this report, the num­bers for the year 2025 were not yet acces­sible. Con­se­quenly, the num­bers for the year 2024 are shown. The num­bers for 2025 are avai­lable on the Sus­tai­na­bi­lity Hub web­site from May 2026 onwards.

2018 is the base year for cal­cu­la­ting the re­duc­tion path re­gar­ding cli­mate neu­tra­lity. In­for­ma­tion re­gar­ding the cal­cu­la­tion method for the green­house gas emis­sions can be found in the Sus­tai­na­bi­lity Re­port 2023/2024 of UZH (in german).

In com­parison to 2018, UZH was able to de­crease its green­house gas emissions in 2024. After a strong de­crease of roughly half the emis­sions during the pan­demic, the green­house gas emis­sions have been rising again since 2021. Con­se­quently, UZH is cur­rently wor­king on further measures to re­duce its green­house gas emissions.
