OECD Companion to the Inventory of Support Measures for Fossil Fuels 2015

This publication is concerned with all policies that directly support the production or consumption of fossil fuels in OECD countries and in a selection of partner economies. It provides a useful complement to the online OECD database that identifies and estimates direct budgetary transfers and tax expenditures benefitting fossil fuels, and from which it derives summary results and indicators on support to fossil fuels, as well as policy recommendations.

The report emphasises the problems that fossil-fuel subsidies cause in the context of broader policy efforts for mitigating greenhouse-gas emissions, and reviews the various reform initiatives that have already been taken at the international level (G-20, APEC, etc.). In addition, it presents the coverage, method and data sources used for constructing the online database, and further discusses caveats and data interpretation.

G20 voluntary peer reviews of the reform of inefficient fossil fuel subsidies

In September 2009, Leaders of the Group of Twenty (G20) economies committed to “phase out and rationalize over the medium term inefficient fossil fuel subsidies while providing targeted support for the poorest.” To follow up on this commitment, members of the G20 have since engaged in a voluntary process of periodically reporting on their fossil-fuel subsidies. In an effort to further facilitate the sharing of experience and mutual learning among G20 members, G20 Finance Ministers announced in February 2013 that they would seek to develop a framework for voluntary peer reviews for rationalising and phasing out inefficient fossil-fuel subsidies that encourage wasteful consumption. 


This led in December 2013 to a joint announcement by the People’s Republic of China and the United States of America that the two countries would undertake a reciprocal peer review of their fossil-fuel subsidies under the G20 process. The OECD was invited to serve as Chair of these reviews. The final versions of the reviews (and of the countries’ own self reviews, which were issued at the start of the process) were issued in September 2016 and can be downloaded from here:

In November 2017, the reciprocal peer reviews of Germany and Mexico, conducted as part of the G20 process outlined above, were published. These reviews were chaired by the OECD.

IEA World Energy Outlook

The global energy landscape is evolving at a rapid pace, reshaping long-held expectations for our energy future. The 2016 edition of the World Energy Outlook (WEO) incorporates all the latest data and developments to produce a comprehensive and authoritative analysis of medium- and longer-term energy trends. It complements a full set of energy projections – which extend from today through, for the first time, the year 2040 – with strategic insights into their meaning for energy security, the economy and the environment. Oil, natural gas, coal, renewables and energy efficiency are covered, along with updates on trends in energy-related CO2 emissions, fossil-fuel and renewable energy subsidies, and universal access to modern energy services.
