Baseline assumptions with all electricity production technologies available.
Rapid reduction in costs of renewable energy technologies; no new builds of nuclear plants; carbon capture unavailable.
Optimistic assumptions about costs of nuclear and CCS technologies; slow decline in costs of renewables; restricted supply of biomass for energy transformation and end-use.
Reduction targets attained in 2050, relative to emissions in 2005.
