NAMAC - Non-Annex I Marginal Abatement Cost curve

Welcome to the website of the Marginal Abatement Cost (MAC) curve for Non-Annex I countries, which ECN has been developing since 1999. The curve results from compiled data of bottom-up country based studies at regional sectoral level and presents greenhouse gas (GHG) abatement opportunities by 2020.

MAC curves describe the expected marginal cost and GHG abatement potential of several mitigation options. In addition to other tools and country specific assessments, these curves are tools for policy makers seeking for sectoral overviews of possible cost-effective mitigation options. The MAC curve tool developed by ECN covers the GHG abatement potential by means of over 1100 country-technology combinations in the non-Annex I region. This curve is updated whenever new relevant studies are published.

Users need to be aware of the approach and the limitations of the MAC curves. A brief description can be found here. Information about operating principles and implementation aspects/drivers for several low carbon technologies can be found here).

The Non-Annex I MAC curve has been used in various studies including:

• Impact of CCS on the CDM (2011)
• Differentiation in the CDM: options and impacts (2009)
• Balancing the carbon market (2009)
• UNFCCC Technical paper: Investment and financial flows to address climate change: an update (2008)
• Carbon credit potential post-2012 (2007)
