Friends of the Earth - Europe's 'Sustainable Europe Campaign', launched in November 199j, entered its second phase recently. The campaign aims at enhancing the development and diffusion of concrete ideas on sustainable development among all the key social groups: business, industry, NGOs, trade unions and other institutions. National teams from 29 European countries have started calculations on how to use the available environmental space. National debates and round tables are being organised in all the participating countries. Inputs for various international debates, including the Pan-European Environmental Ministers' Conference to be held in Sofia in October 1995, are being finalised.
