Because I have just read it a few days later and it would slot in a treat here, let me add this not disimilar set of thoughts on the matter from FOE.
And with another day, another viewpoint, this time from the business section of The Independent (answering my first question, and adding weight to my subsequent musings)...
"To counter the negative publicity being drummed up by lobby groups, there is to be £100m for environmental initiatives - everyone is clambering aboard this bandwagon, it seems - and some sort of "multi-pronged" community plan is about to be hatched in an attempt to make Tesco seem even more warm and cuddly than it already likes to think it is. In so doing the company plans to go beyond the rampant consumerism of its message to date of "every little helps"."
...and The Telegraph:
"With yesterday's annual result came details of a £100m investment in wind turbines, solar energy and geothermal power for its new stores. If this were a vacuous political statement to buy off the "green lobby" it would be a very expensive mistake. In fact it is simply the latest investment, and there will be more to come, in what in Terry Tesco's judgment will be the next big thing for supermarkets."
I'm kinda hoping they are on the money, as this means that at last business may be seeing doing the right green thing to be an opportunity. Breath is being held as we speak.
