Going long on carbon

From Martin Waller's Times of London City Diary column:

Some query whether the markets that allow trading in carbon emission permits are a mere passing fashion. One market veteran has apparently decided they are here to stay. I hear that Brian Williamson is joining the board of AIM-listed Climate Exchange, which owns the European Climate Exchange. He did two spells as chairman of Liffe, so was instrumental in creating the last big manufacturing market to arrive in London.
