Transport accounts for nearly a quarter of carbon dioxide emissions from fuel combustion. The price attached to these emissions is critical to climate policies and emissions mitigation efforts in the sector. As the impact of emissions on climate does not depend on where CO2 is released, the price of carbon should be uniform. In reality, however, it varies immensely, reflecting the complexity of assessing climate impacts.
This report reviews the three key challenges in considering the effects of carbon dioxide emissions in economic appraisal: the valuation of carbon dioxide emissions, the treatment of uncertainty in climate change and the approach used to discounting future costs and benefits. The report reviews current approaches in selected countries (France, Germany, Japan, The Netherlands, New Zealand, Norway, Sweden, the United Kingdom and the United States) and provides examples of good practice and recommendations for national and international policy making.

Tackling climate change will require action in three key areas. First, we must strengthen carbon pricing and remove fossil fuel subsidies. Second, we must remove barriers to green investment. And third, we must align policies across the economy to leave fossil fuels behind and improve transparency on climate finance.
This project is unique in that it explores how national-level policies impact household behaviour. Topics include energy use, food consumption, personal transport choices, waste generation and recycling, and water consumption. Yet the project does not specifically discuss the term “ecological footprint,” and it retains a macro-policy focus, targeting governments interested in learning which policies to implement.
Read the latest articles on climate change by the OECD Observer, which helps policymakers stay ahead of today’s pressing challenges.
This report on climate change disclosure in G20 countries takes stock of mandatory climate change reporting schemes in G20 countries and identifies commonalities and divergences between the various schemes.
To increase transparency and improve understanding of different countries’ situations, the OECD has developed an interactive map that brings to life key climate change mitigation statistics and policy settings. The webinar on Monday 16 November 2015, 15h00-16h30 (Paris time) consisted of a summary of the main messages of the report "Climate Change Mitigation: Policies and Progress" and a demonstration of the interactive tool.
How have CO2 and greenhouse gas (GHG) emissions changed since 1990? Three different visuals tell three very different stories (click on them to see full size). Which perspective offers the most clarity?
Brazil has made remarkable social and economic progress in the past two decades, but must now overcome important challenges if it is to put its economy on a stronger, fairer, greener growth trajectory, according to two new reports from the OECD.
"Back to the Future" festivities marking 21 October 2015 as the date Marty and Doc travel to the future in the famous film with Michael J. Fox. If only we had a similar time machine allowing us to travel to 2045 to see what the climate has in store to better decide what policies to adopt today. Alas, no time machine has been invented yet but, in the absence of such a cool device, we can rely on climate and economic models...
This report provides a new detailed quantitative assessment of the consequences of climate change on economic growth through to 2060 and beyond. It focuses on how climate change affects different drivers of growth, including labour productivity and capital supply, in different sectors across the world. The sectoral and regional analysis shows that while the impacts of climate change spread across all sectors and all regions, the largest negative consequences are projected to be found in the health and agricultural sectors, with damages especially strong in Africa and Asia.
