Mitigation from a Cross-sectoral perspective

This chapter takes a cross-sectoral approach to mitigation options and costs, and brings together the information in Chapters 4 to 10 to assess overall mitigation potential. It compares these sectoral estimates with the top-down estimates from Chapter 3, adopting a more short- and medium-term perspective, taking the assessment to 2030. It assesses the cross-sectoral and macroeconomic cost literatures since the Third Assessment Report (TAR) (IPCC, 2001), and those covering the transition to a lowcarbon economy, spillovers and co-benefits of mitigation.
