Interesting but little known and little appreciated; The Kyoto Protocol charts a soft energy path:

"As industrialised nations take on commitments to limit CO2 emissions as required under the Climate Change Convention (Kyoto Protocol) and/or implement national legislation, some electricity industries (utilities and nuclear advocacy groups) and certain nuclear power producing countries have suggested that nuclear power is one of the central means to combat climate change.

This lobby considers nuclear a key technology in achieving climate protection commitments. This is not, however, consistent with recent decisions in the global community. The finalised rules of the Kyoto
Protocol exclude nuclear from the Clean Development Mechanism (CDM) and Joint Implementation (JI). This does not, however, have a direct impact on national decisions to run existing plants or install new nuclear facilities anywhere in the world."
