We now know that climate change is a driver of migration, and is expected to increase the displacement of populations.

I do not support individual countries taking military action against another country because of its human rights record, or subsequently justifying taking such action on human rights grounds.

The whole human rights structure is based on the accountability of governments.

There are some parts of the business world, in my judgment, that are actually trying to ensure that the U.S. does not take on board the preponderance of arguments for global warming, and that is something I am really very concerned about.

The UN may not be very effective but I am a fan of the idea of the United Nations. I have been there, I know the problems. To parody Winston Churchill: It is the worst system, except we don't have any other.

Democratic governments are not delivering on their promises, which is partly due to the fact that governments are less powerful than they were after the Second World War. There were fewer governments then, but they actually had more political power.

In human rights theory it is very important that governments still have the primary responsibility for the standards and provision of such services even if they no longer deliver them. They must insist that the private sector delivers without discrimination. So governments still have responsibility, including the need to influence business.
