What the 191 members of the United Nations have “pledged to do” “by the year 2015.” A good list. Specifically environmental goals (e.g. taking measures to prevent global warming) are not included—perhaps because they were too controversial, but also, possibly, because they don’t score very highly on the cost/benefit equation.
(The much longer Millennium Declaration, I now notice, does include some environmental aims, such as ratification of the Kyoto Protocol.)
