Iranian President Mahmoud Ahmadinejad has left Tehran for Copenhagen to attend a UN sponsored conference on climate change.
Ahmadinejad is due to deliver a speech at the summit on Thursday. A high-ranking political and economic delegation is accompanying the president.
On the sidelines of the summit, Ahmadinejad will hold talks with some foreign leaders and meet Iranian expatriates in Denmark as well.
Before leaving Tehran, Ahmadinejad told reporters that Iran is very concerned about climate change and would present strategies to control global warming.
He called on the countries most responsible for environmental damage to demonstrate greater commitment to protect the globe.
The climate change conference in Copenhagen will wrap up on December 18.
Heads of states and representatives from 170 countries have convened in Copenhagen to meet for the last time to concentrate efforts on coming up with a new climate protocol.
The Kyoto Protocol to prevent climate change and global warming runs out in 2012.
