Scottish Environment Protection Agency
Probably one of the best designed official sites: contains all sorts of up-to-date material, an education section, and interesting historical statistical data. Guidance on the legislation, sorted by sector, in Scotland and Northern Ireland can be had on sister site NetRegs: www.netregs.org.uk. Meanwhile, www.sepaview.com is SEPA’s online magazine providing environmental news, features and analysis.
The equivalent to the Scottish site: lots of free and useful information and data.
An enormous list of links to just about every environmental law issue and country. Last updated in 2013.
Friends of the Earth
The Scottish and the English Campaigns are separate and have their own sites, both of which contain a lot of information about the work of the Campaigns and a limited amount of information about the legal issues.
