A new version of the PAGE model, PAGE2002, has been used to calculate the marginal impacts of CO₂, CH₄ and SF₆ emissions based on Scenario A2 of the IPCC. The mean marginal impact of CO₂ is found to be US$19 per tonne of carbon (or about US$5 per tonne of CO₂), for methane it is US$105 per...

The social cost of carbon (SCC) is the value of the climate change impacts from 1 tonne of carbon emitted today as CO₂, aggregated over time and discounted back to the present day. We used PAGE2002, the same probabilistic integrated assessment model as used by the Stern Review (Stern et al.,...

At the recent UN climate negotiations in Bali, most countries sought an agreement to cut industrialized countries' emissions of CO₂ by between 25% and 40% by 2020. The final agreed wording at Bali was that 'deep cuts' in emissions were required, without further quantification. The PAGE2002...

This study quantifies the costs and impacts of six scenarios for carbon dioxide(CO₂) and sulphur dioxide(SO₂) emissions in North East Asia(NEA) within an integrated probabilistic analysis. The inclusion of the cooling effect of sulphates means that CO₂ control in China would be likely to...
