Well actually, not quite.
As a former active environmentalist (back in the early 1990s when I had hair) and as a proud keeper of ducks, I obviously support their move.
Fabrication technologies also have the possibility to be more environmentally friendly as well.
Though I'm not involved with the environmental movement today, I obviously have concerns about such issues. At ETech in Mar' 2007 and OSCON we demonstrated a mashup of GoogleMaps and a Carbon offset calculator in Zimki. A more impressive system is Will Carter's OffSetr which uses Dopplr data and provides cumulative effects of your networks.
I do however oppose the idea of widespread use of tradeable carbon permits as this is a mechanism for social exclusion. A more equitable system would be based upon non-transferable personal share which gives rise to an annual carbon quota. That quota (or part of) can be sold on an open market, but the the right to that share cannot be transferred.
I am also fully aware that such as system is a bit of disaster for anyone living in the richer countries, as we produce far too much carbon per capita and under such a system we'd be forced to share more with the rest of the world.
I also believe that each country should pay for the cumulative damage it has caused so far.
I also believe that the likelihood of the richest countries agreeing to such things are relatively small, and hence any 3rd world country should avoid tradeable permits and pollute as much as is necessary to build their economies in order to avoid lifelong servitude and hence force richer countries to negotiate reasonably.
I'm fully aware of all the risks of inaction and I stopped working in the environmental field when it became obvious that change would only happen as a result of severe consequences. At which point it is a guessing game.
Still anything to improve the lot of ducks is a good thing in my book.
