Objectives

• Impartial, coherent and transparent comparison of GHG mitigation potentials and costs in Annex 1 countries

– using a multi-disciplinary systems approach,

– based on publicly available data,

– taking into account co-benefits on air pollution,

– independent assessment, financed through IIASA’s core funds.

• Results, input data and an interactive calculator freely available in the public domain:

http://gains.iiasa.ac.at

Methodology

Bottom-up approach:

• all gases and sectors,

• at detailed technical level (several 100 source categories, 300+ mitigation measures, etc.)

• systems approach (integrated perspective covering demand and supply sectors),

• consistent with UNFCCC 2005 inventories,

• employing exogenous activity projections,

• technical, economic and market potentials (before trading).

Based on earlier work with IIASA’s GAINS (Greenhouse gas – Air pollution Interactions and Synergies) model

An initial implementation

• For largest Annex 1 countries (98% of 1990 emissions), EU27 presented in aggregate

• Based on activity projections of IEA World Energy Outlook 2008 and FAO World Agriculture Perspective

• Key assumptions:– Only currently available technologies– Natural turnover of capital stock, no premature scrapping– No behavioural changes– Domestic measures only– LULUCF excluded for now

• Initial analysis compiled from publicly available information, received only limited review by national experts up to now

Conclusions

• IIASA’s GAINS analysis:

– Coherent and impartial comparison of mitigation efforts

– Analysis based on publicly available data

– Transparency: Open access to results and all input data:

http://gains.iiasa.ac.at

– Review workshop in May/June 2009

• The analysis quantifies impacts of objective reasons for differences in mitigation efforts.

• Different equity criteria deliver different rankings of countries.

• The GAINS calculator provides a practical tool for comparing mitigation efforts along multiple criteria.
