This brochure provides key lessons learnt from OECD work on adaptation, including challenges and recommendations for climate adaptation, with a focus on OECD member countries.
"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...
More than 150 countries have submitted their post-2020 Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change (UNFCCC). Such contributions are vital to the #COP21 climate change conference in Paris this December.
It has become the accepted wisdom that meeting the global climate challenge will require zero net greenhouse gas (GHG) emissions by the end of this century. Read the full op-ed by Gabriela Ramos, OECD Special Advisor to the OECD Secretary-General.
Cost-benefit analyses and other quantitative appraisals are used in many countries to support decision-making in public policy, including investment projects in sectors such as transport and energy. This paper discusses the range of approaches which can be employed to value changes in carbon emissions in policy appraisalsand presents some case studies and a survey of current practice in OECD countries.
La transition vers une économie bas carbone est réalisable, mais nécessite davantage de concertation et de cohérence à travers un éventail de mesures gouvernementales, allant des permis échangeables à des normes strictes.
Climate change is giving rise to diverse risks, ranging from changing incidences of tropical diseases to increased risks of drought, varying widely in their potential severity, frequency and predictability. Governments must integrate the management of these climate risks into policy making if they are to successfully adapt to a changing climate. Economic analysis has a vital role to play in supporting these efforts, by identifying costs and benefits and supporting decision-making for an uncertain future. However, this analysis needs to be adapted to the institutions, policies and climate risks in a given country. Building on the experience of OECD countries, this report sets out how the latest economic evidence and tools can enable better policy making for adaptation.
This report produced in co-operation with the International Energy Agency (IEA), the International Transport Forum (ITF) and the Nuclear Energy Agency (NEA) identifies the misalignments between climate change objectives and policy and regulatory frameworks across a range of policy domains (investment, taxation, innovation and skills, trade, and adaptation) and activities at the heart of climate policy (electricity, urban mobility and rural land use).
Outside of countries’ core climate policies, many of the regulatory features of today’s economies have been built around the availability of fossil fuels and without any regard for the greenhouse gas emissions stemming from human activities. This report makes a diagnosis of these contradictions and points to means of solving them to support a more effective transition of all countries to a low-carbon economy.
