Nicholas Stern: "With 10 ... 15 billion dollars per annum we can cut deforestation by half. That will give us carbon reductions at a price of 10 ... 15 dollars per ton of CO2." (Anmerkung: Wenn Deutschland allein das Geld für das Wald-Erhaltungsprogramm aufbringen würde, kostete das jeden der 80 Millionen Deutschen 34 ... 51 Cents pro Person und Tag.) "You have to go into the evidence quite carefully, for this to be true you'd have to do some experiments, to make sure you're using the right kind of methods, and you have to have those experiments run by the countries in which the trees stand. It'd be quite wrong for those outside to go around telling people about how to do that, but there's the obligation of those outside to support those who try to take on these tasks. ... around half of it could be done at about 5 dollars per ton CO2 equivalent (umgelegt auf 80 Millionen Deutsche wären das 14 Cents pro Person und Tag). McKinsey doesn't agree with that but I think they got it wrong.
Carbon capture and storage (CCS) would be absolutely crucial. India and China will use coal, probably so will Poland, probably so will Germany ... So we have to help get good at CCS ....
- Demonstrating and sharing of technologies,
and we ought to be as economists and public policy people concentrating very hard on just how we share the technologies.
- Do we have buyouts of patents,
- do we give incentives for joint ventures so that the know-how can be shared, how's that going to be done,
there's lots of difficult eonomics in public policy to make that happen. ... we need to operate much more quickly.
The climate is going to change on us, ... and it's going to be particularly difficult for the developing countries. I draw your attention to the "Human Development Report" which was published by UNDP about a month ago. They argued that in 2015 (we are talking about 0.8 or 1 degree centigrade temperature increase) that the extra costs facing the developing countries because of climate change might cost them another 85 billion dollars a year (umgelegt auf 80 Millionen Deutsche wären 2.74 Euro pro Person und Tag). I think that's quite conservative. That's roughly the same order of magnitude as total overseas development assistance. If we doubled overseas development assistance by 2015 the costs of climate change eats up roughly half of the new level of development assistance. These [climate change related costs] are costs -we're talking about the near future now- imposed on poor countries by rich countries . That is a responsibility -it seems to me- that we have to look at directly. And again, if we are talking about the equity characteristics of the global deal that would bring developing countries into the story, I think at least delivery on the promises of overseas development assistance is absolutely necessary, and we can't wring this out of the environment ministers' discussions, it has to be a seperate discussion in terms of different ministeries integrated in that environmental discussion."
