The university encourages hitchhiking, but stresses the risks and provides safety guidelines to both drivers and passengers. New staff are required without exception to live within 20 miles of campus. The nett unit price of natural gas has increased due to international global warming taxes, so the overall cost to the university has fallen little since 1998. General recycling and waste minimisation. Most office-grade paper sent for recycling is printed on both sides.
Some staff receive and mark written work by email.
But costs associated with the collection, transport and dumping of non-recycled rubbish have fallen relatively little, due to increased landfill taxes. In new and some old buildings, rainwater is collected for non-drinking purposes, and some grey water is recycled for toilets. Water meters are installed in all staff flats and houses. Taps in residences turn off automatically after a given period. Toilets have a choice of two flush quantities.
