Any decisions either to extend the lifetimes of nuclear plants, or for early retirement of plants, will have a major impact on emissions, unless carbon-free alternatives are available. Several Parties have expanded, or plan to expand, nuclear power generation (Croatia, Czech Republic, Finland, Japan, Switzerland). The Czech Republic reported that the Temelin plant was brought on line over 2001-2002, but that up to 2020 no new plants were planned. Japan noted that its programme for new plants has fallen behind the schedule set out at the time of the NC2. Extending the lifetime of existing nuclear plants is considered by some Parties to be a cost-effective means of reducing GHG emissions. The United States reported on a major research and development programme on lifetime extension. Finland considered constructing a new, fifth nuclear unit as a GHG mitigation option.
