=== Energy ===
Basel is at the forefront of a national vision to more than halve energy use in Switzerland by 2050. To research, develop and commercialise the technologies and techniques required for the country to become a [[2000-watt society|2000 Watt society]], a number of projects have been set up since 2001 in the Basel metropolitan area. These include demonstration buildings constructed to [[Minergie]] or ''[[Passive house|Passivhaus]]'' standards, electricity generation from [[renewable energy]] sources,<ref>{{cite web|url=http://www.swissinfo.org/eng/front/detail/swissinfo.html?siteSect=105&sid=7407138|title=Geothermal project shakes Basel again|work=SWI swissinfo.ch|access-date=1 September 2015|archive-date=30 May 2008|archive-url=https://web.archive.org/web/20080530231218/http://www.swissinfo.org/eng/front/detail/swissinfo.html?siteSect=105&sid=7407138|url-status=dead}}</ref> and vehicles using natural gas, [[hydrogen economy|hydrogen]] and [[biogas]].<ref>{{Cite web|url=http://www.basel.ch/en/basel/urban_development/2000_watt_society|archiveurl=https://web.archive.org/web/20090111061314/http://www.basel.ch/en/basel/urban_development/2000_watt_society|url-status=dead|title=The Basel pilot region of the 2000 Watt Society|archivedate=11 January 2009}}</ref>

A building construction law was passed in 2002 also which stated that all new flat roofs must be greened leading to Basel becoming the world's leading green roof city. This was driven by an energy saving programme.<ref>Carter, J.G. 2011, "Climate change adaptation in European cities", Current Opinion in Environmental Sustainability, vol. 3, no. 3, pp. 193–198.</ref> A [[Enhanced geothermal systems|hot dry rock geothermal energy]] project was cancelled in 2009 since it caused [[induced seismicity in Basel]].
