The average amount of paper purchased in 2010-2011 was 26.5 tons, i.e. 9.6% lower than in 2009 (29.3 tons), which corresponds to a per capita consumption of 3.2 tons (a decrease of 12% compared to 2009). In 2011 (4.85 x 106 of printed pages) FEUP printed 1.4 million fewer copies than in 2009 (-23%).
2011 saw a slight decrease in electricity consumption (6,85 x 106 kWh) compared with the previous year (2%), with 803 kWh per member of the academic community being metered. It is worth stressing that, compared with 2010, electricity consumption per member of the academic community decreased by 4%.
Consumption of natural gas has declined over the past 4 years, consumption in 2011 being 107,831 m3, corresponding to 13 m3 per capita.
In 2011 water consumption increased (27%) compared with 2010, recording a figure of about 48,000 m3, equivalent to 5.6 m3 per member of the FEUP community. The increase may be due to water consumption in new laboratories.
No withstanding this increase in water consumption, it is worth noting that in 2011, there were a considerable number of taps which were replaced by "saver" models, which ensure the same efficiency by means of a nozzle with more jets and greater dispersion, consuming only 30% of water compared to the older taps.

FEUP has about 23,000 m2 of green spaces (27% of the total area of the institution), where you will find 24 olive trees from Alqueva which, due to the construction of the dam, were doomed to disappear. Their re-utilization constituted the commencement of the beautification and enhancement of the green spaces and landscaped environment of the FEUP campus. This reclamation of the natural vegetation, an essential aspect of FEUP’s environmental strategy, deserves to be highlighted as a further contribution to the sustainable development policy pursued by the Faculty.
