How can you judge the quality of the water that comes out of your tap or the air you breathe? Is it better or worse than in other neighbourhoods? How well does it conform to the government's environmental objectives? The obvious answer is to go online, but how easy is it to make a judgement based on the kind of information provided? This study explores these very questions for two sample households in Berlin-Mitte and London Tower Hamlets. The findings confirm the potential of the internet, but also indicate that much more could be done and that a coordinated policy strategy is lacking.(Original source: http://www.agf.org.uk/pubs/pdfs/1489web.pdf)
