Irrational incandescence

May 31st 2007
From The Economist print edition

SOME ways of cutting carbon are cheaper than others. So, at different carbon prices, different sorts of methods of abatement become worthwhile. Vattenfall, a Swedish power utility, has tried to quantify which ones would be worth undertaking at what price (see chart 3).

The result is a testament to economic irrationality. The measures below the horizontal line have a negative abatement cost—in other words, by carrying them out, people and companies could both cut emissions and save money. At a macroeconomic level they would boost, rather than reduce, economic growth.
