All major problems cannot be solved unilaterally, she stressed, calling for unity of purpose among the world’s countries to deal with such challenges. Commenting on Iran’s nuclear activities, Ms. Merkel described them as a clear breach of the demands of the UN and its International Atomic Energy Agency (IAEA). Turning to climate change, Ms. Merkel said unity of purpose was also vital and she urged participants at the major summit in Bali, Indonesia, in December to agree on a clear road map so that a successor to the Kyoto Protocol on the reduction of greenhouse gas emissions can be developed. The world must halve global emissions by the middle of this century, she said, calling for a common understanding between nations on the scale of emissions reduction, fair national contributions and the mechanisms needed to protect both the environment and sustainable economic growth.--SPA www.spa.gov.sa/485953
