Compendium on methods and tools to evaluate impacts of, and vulnerability and adaptation to, climate change

PAGE2002 (Policy Analysis for the Greenhouse Effect)
Description

PAGE2002 is a spreadsheet probabilistic model written in Microsoft Office Excel with the @RISK add-in. The model calculates regional and global impacts of climate change, and social costs of different greenhouse gases. It also calculates the costs of abatement and adaptation. It is an Integrated Assessment Model starting from emission projections, and carrying uncertainties throughout the calculations.

Appropriate Use The model is designed to explore the impacts and social costs under any user-specified emission scenarios. It can be used to calculate optimal abatements.
Scope The model is global in scope, with a user-defined focus region. It calculates to 2200 by default.
Key Output The model and the results obtained with it are the key outputs.
Key Input Emission scenarios and about 80 parameter probability distributions covering both scientific and economic inputs.
Ease of Use Designed to be transparent and easy to use.
Training Required A single session with the model developer is all that is normally required.
Training Available The model developer will offer advice and support under contract.
Computer Requirements PC running Microsoft Office Excel and @RISK.
Documentation PAGE2002 is described in detail in Hope C, 2006, “The marginal impact of CO2 from PAGE2002: An integrated assessment model incorporating the IPCC's five reasons for concern”, Integrated Assessment, 6, 1, 19-56.
Applications

Several analyses performed for the GB Office of Gas and Electricity Markets who paid for the development of the model. PAGE2002 was the main model used for the impact calculations in the UK Government’s Stern report.
