The document discusses achieving targets to limit global warming to 2°C, including concentration targets of 450ppm and 550ppm of CO2 by 2050. It outlines emission reduction targets needed from developed and developing countries to achieve these concentrations. It also analyzes scenarios for Australia's electricity sector to meet emission reduction goals of 1990 levels or 60% below 1990 levels by 2050, exploring uncertainties around gas prices, technology availability, and the rate of reducing emissions. Key findings are that carbon capture becomes competitive only with high early emission cuts, and renewable energy and nuclear power are most competitive alternatives if carbon capture is infeasible.
