Why has Russia been so absent from the climate change debate?

A not often discussed topic: Russia and renewable energy sources.

I'd like some more specific information on the development of renewables in Russia, but this is a good general article on the issue from the NYtimes.

Despite its massive pollution, the collapse of the Russian economy in 1992 drastically reduced its carbon emissions. However the country remains woefully inefficient in energy use and still relies heavily on manufacturing rather than services.

I suppose world leaders have other major issues on their minds such as security of energy supply rather than getting Russia to lower carbon emissions and increase energy efficiency. However more renewables in Russia would mean savings for them, more hydrocarbons to sell and more for Europe to buy.

However any major change would require political will that Russia likley just does not have at the moment.
