In part 2 Sterner starts by continuing the comparison of fuel prices and fuel use between the US and the UK.
He moves on discussing whether fuel taxes are generally progressive or regressive, in other words if they affect the rich or the poor most. He gives the example of South Africa and illustrates how the richer part of the population is also proportionately using more of their money on fuel than the poor (not only in absolute numbers) and are hence affected more by higher prices. The same is true in Kenya, even when you include traveling with public transportation.
Sterner then mentions what he believes is the main reason to why the climate negotiations are so tough and why it so hard to reach an agreement.
He then starts telling about his experiences working with the IPCC and their third and latest climate report, although the last part is no published since it contains some sensitive information.
The first IPCC reprot was dedicated to what is actually happening in nature, the second about the effects on humanity and this one about what we can do about it.
