Some comments
* How is a 'summit' != a 'conference' (or a 'round table' for that matter)? 'Summit' sounds a lot more high- falutin, but in the end ain't it a bunch of suits around a table swapping presentations?
* Isn't Asda the UK version of Wal-Mart? If so, they could consider sourcing more of their product from in-country to cut down on the emissions required to cargo-ship stuff from overseas (where environmental regulations tend to be less robust -- great 2 for 1 deal, no?) while also creating more jobs at home (economic stability).
* Too many "environmental" groups seem to have been 0wn3d by corporate polluters (see http://www.thenation.com/article/wrong-kind-green for some examples), so they might not be the great counterbalance one expects.
* "Growth for the sake of growth is the ideology of the cancer cell." -- Edward Abbey. Clearly, some growth will be needed to bring developing nations to levels of self- sufficiency, but I am concerned that any money thrown in this direction will be for wheel- spinning and handing out of fish instead of education, infrastructure, and other long-term "deep" foundations needed for residents to fish for themselves.
