I am retired from all my official roles, but I am still very active. I have close relationships at the U.N. I don't have any role at the U.N, but I'm still quite cooperative with a number of U.N. activities, in particular to China and that region.

I've got used to criticisms and, naturally, I try to make sure I don't listen to the more extreme ones because most of the people who have taken their rightwing extremist view of my life are people that I've never met.

I've developed a huge regard for Toyota for its environmental awareness, for its immense commitment to research and development in this field, and for its leadership in developing hybrids which others are now following.

The combination of population growth and the growth in consumption is a danger that we are not prepared for and something we will need global co-operation on.

Don't accept that you can't make a difference. Because if you can't make a difference, you won't make a difference, and if you put a multiplier on that we will continue on an unsustainable pathway.

I am President of the UN created University for Peace, which has a strong commitment to the relationship between peace, security and the environment. I meet with young people around the world and I always come away enthused and encouraged.

Anyone who is seriously interested in me would usually do a little more homework and realise that the extreme criticisms are almost exclusively ideologically based.
