Migros (supermarkets) sponsored AquaClics for schools and kindergartens
The Migros sponsoring + corporate volunteering project in detail:

AquaClic screw-on accessories limit water flow by about half, thus saving energy that would have been used to heat water, resulting in a substantial reduction in CO2 emissions.
The aim of the campaign is to save 701 tonnes of CO2 a year* by fitting water-saving attachments to over 1000 taps and showers.
The water-saving tap and shower attachments were supplied by Migros, who stock them at their Do It + Garden stores.The campaign is financed by Migros, but the institutions who received the accessories were asked to make a donation to a myblueplanet climate protection project.
The volunteers worked on the campaign during office hours. Migros employees organised the campaign in collaboration with myblueplanet, in the cantons of Zurich, Bern, Schaffhausen, Lucerne, Zug, Aargau und Thurgau.
Migros is engaged as one of the BlueCompanies with corporate volunteering, and also sponsors myblueplanet.
*By comparison: 70 tonnes of CO2 correspond to a saving of 23,000 litres of heating oil. This amount of oil is sufficient to heat eleven family homes for a year.
