聯合國氣候問題高級官員德布爾(Yvo de Boer)表示，「無論這個政治社群是否願意在峇里島的會議中，推動2012年後氣候變遷機制的全面性計畫，此次維也納氣候變遷會談，代表氣候變遷過程中測量氣溫的一項機會。」
Climate change talks that opened Monday have drawn 1,000 people from over 150 governments, business and industry, environmental organizations and research institutions to Vienna. The delegates are seeking to build the political will to limit global warming ahead of an international climate summit set for December in Indonesia that will determine what happens after the Kyoto Protocol expires at the end of 2012.
"The Vienna Climate Change Talks present an opportunity to measure the temperature of the climate change process - whether or not the political community is willing to advance a comprehensive agenda on a future climate change regime post-2012 in Bali," said the top UN climate official, Yvo de Boer.
The Kyoto Protocol, the current global framework for reducing the emission of greenhouse gases responsible for global warming, is seen as merely a first step because does not include many major emitters such as the United States, China, India, Brazil, Mexico and South Africa.
Today, the Vienna meeting is discussing a new UN report that examines the financial aspects of climate change over the next 25 years. The report takes into account the need to limit global temperature rise to 2°C, the level at which scientists say the worst effects of global warming may be averted.
The financial report says that by 2030 additional investments of up to US$210 billion a year will be needed to return greenhouse gas emissions to the current level.
