"The situation with the so-called post-Kyoto period agreement, which, according to current plans, will be valid from 2012 to 2020, is already beginning to find itself in a dead-end, as most countries, including Russia and the U.S., are not ready to undertake the commitments proposed there on the further reduction of greenhouse gas emission volumes," he told RIA Novosti.
Chestin said the only way out was to extend the validity period of the new agreement until 2030. "This will cardinally change the whole structure of the issue... many countries will develop more environmentally friendly technologies and reach the required levels of emission reduction," he said.
The Kyoto Protocol obliges the 35 industrial states that have ratified the document to cut emissions by 5% below 1990 levels by 2008-2012. The United States, a major polluter, has pulled out from the protocol, saying this could damage its economy.
Developed and developing countries have been locked in a dispute over who should bear the main burden of carbon emission restrictions.
Chestin said the peak of greenhouse gas emissions in Russia would be in 2015-2017, and added that, according to experts, by 2030 Russia would be again at the current 2005-2007 level of emissions, some 30% less than in 1990.
The signatory countries will consider the post-Kyoto agreement issue in December 2007 at a UN conference on climate change in Bali.
