The Sustainabul

In 2015 we noticed that Leiden University was the only university in the Netherlands that was not participating in the Sustainabul. The Sustainabul is a ranking, set up by Studenten voor Morgen, to measure the sustainability of the educational institutions nationwide. So we started a petition and ended up convincing the executive boards that we really needed to participate.  In the first year (2015) that Leiden University participated in the ranking it scored fairly low, 15th place. However, since then the University has improved and as of 2016 it scored 5th place. Follow this link to see the current ranking. (Dutch). 

 The Environmental Policy Plan (2016)

In collaboration with the university, Green Keys developed the institution’s environmental policy: Leiden University Environmental Policy Plan 2016-2020. In this document the policy of the university concerning reduction of their impact on the environment as an institution, the education and research concerning theenvironment at the university and the visibility and communication of the sustainability at university, and of this policy, is presented. Key-aspects discussed in the policy are: energy, water, sustainable housing, sustainable purchasing and investing, waste, mobility, education and research, awareness and involvement, and organisation and execution.To see the full article you can go to the following link.

  Sustainability Trophy (2016)

Every study year the board of the University organises a small reception for all active student organisations and associations of the university. During this occasion the Duurzaamheidstroffee (Sustainability Trophy) is handed out to the best/most green initiative from any organisation/individual for the students and university.  Green Keys Leiden Functions as the key advisor for the awarding of this prize. This year the prize was awarded to the student association of V.S.L. Catena for their sustainable festival during the summer. It was a great initiative sinds it was an energizing and fun student activity and at the same time an almost completely sustainable event.

 Warme truiendag (2018)

Leiden University will participate for the third time in the “Warme Truiendag” on February 2nd this year. Each year Greenchoice and the Klimaatverbond organise a national “Warm Sweater day”, a day to be conscious about your energy use and to collectively turn down your heating to save energy. On this day the heating in the classrooms within five of the 7 faculties of the university were turned down a few degrees. This was all possible in collaboration with the university and the faculties of Humanities, Social Science, Law, Archaeology and Science.
During this day free Chocolate Milk will be handed out to the students and information on how to live a little greener is also available. Because of the enthusiastic and encouraging reactions we received from staff and student we would like to call it a great success.
