The US Labs21 programme has developed a number of on-line toolkits.
The Environmental Performance Criteria below has been 'lightly'
adapted for the UK:
Note that, because the toolkits were developed by different
sub-contractors in the US, there is some overlap of content
between them. For the same reason, they are also set up as self-contained
sub-sites, appearing in a new browser window (so pop-ups must
be enabled). Unfortunately, it is not possible to navigate from
these sub-sites to the main Labs21 UK site.
