Expert Workshop on Estimating Support to Fossil Fuels, 18–19 November 2010


OECD Conference Centre, 2 rue André Pascal, 75016 Paris, France



In September 2009, leaders of the Group of Twenty (G-20) economies committed to “Rationalize and phase-out over the medium term inefficient fossil-fuel subsidies that contribute to wasteful consumption.” At the same time, they called upon other nations of the world to join them in this action, while recognizing the importance of providing households in need with essential energy services. They also requested that the OECD, along with the IEA, OPEC and the World Bank, “provide an analysis of the scope of energy subsidies and suggestions for the implementation of this initiative and report back at the next summit.”

One outcome of the joint work of the IEA, OPEC, OECD and the World Bank was a new set of estimates of fossil-fuel consumer subsidies, updating the estimates used in the 2009 analysis of the effects on GHG emissions of phasing out the subsidies. The work (and the report of the G-20 Energy Expert Group) also revealed a number of examples of tax expenditures that are being used to support production or consumption of fossil fuels, including by OECD countries. Work commenced on trying to identify more cases of tax expenditures and other forms of subsidies supporting fossil fuels in OECD countries, but that effort is still on-going.

Objectives and participants

Understanding the extent and nature of fossil-fuel subsidies, especially in an international context, requires a consistent method for identifying and estimating the transfers associated with various support; a framework for aggregating them; and a set of common support metrics. This expert workshop aims to begin that process by bringing together national government experts on measuring tax expenditures and other forms of domestic support, along with a selected group of experts from academia, other inter-governmental organizations, and non-governmental organisations with a shared interest in the issues under consideration.
