What @paulkrugman says about green growth and degrowth is not only wrong - it is dangerous. Here is why.

Krugman argues that "despite lots of economic growth, British CO2 per capita is back down to the levels of the 50s — the *1850s*. Emissions reflect choices, not the level of GDP."

Even though they're rather small (2% of the footprint of aviation), private jet emissions are growing even faster than commercial emissions.

In a single hour, a private jet emits 2t of CO2, which is the individual yearly footprint we should be aiming for. On average, a private flights pollutes 10 times more than its commercial alternative.
