Energy efficiency improvements over the last 25 years saved a cumulative USD 5.7 trillion in energy expenditures. This virtual supply of energy generates multiple benefits for governments, businesses and households, including greater energy security from reduced dependence on energy imports and billions of tonnes of greenhouse gas emissions reductions.
Strengthening our understanding of the energy efficiency market and the prospects over the medium term is becoming increasingly important. The 2015 Energy Efficiency Market Report (EEMR) evaluates the impact of energy efficiency in the energy system and assesses the scale and outlook for further energy efficiency investment using detailed country-by-country energy efficiency indicator data and IEA expertise.
This year’s report includes an in-depth look into the buildings energy efficiency market and the electricity sector. Energy efficiency investments in the buildings sector totalled between USD 90 billion in 2014. In the electricity sector, energy efficiency has proved critical in flattening electricity consumption in Organisation for Economic Co-operation and Development member countries, driving utilities to adapt their business models.
Promoting and expanding energy efficiency markets is a worldwide phenomenon, and EEMR 2015 presents a number of case studies at the national, state and municipal level. These include examinations of Latin America’s two largest economies, Brazil and Mexico, which are looking to efficiency to boost productivity and social development. Energy-exporting countries like Saudi Arabia and the Russian Federation are also increasingly turning to efficiency to increase exports and reduce the costs of growing domestic energy consumption. In addition to national governments, major urban areas such as Tokyo, Seoul and Paris are increasingly enabling energy efficiency investment.

The rapid development of tourism and energy-intensive industry is exerting increasing pressures on the environmental assets upon which much of Iceland’s growth has been founded.
As we approach COP21 it is becoming increasingly clear that more ambition is needed to get us on a 2 degree pathway. But it is not just about committing to emission reduction targets by 2030. Governments need to demonstrate how their policies will credibly put them on a pathway to even deeper reductions.
The current Volkswagen diesel emissions scandal highlights the difficult reality of making the transition to a low-carbon economy. It also highlights the growing need for governments to make smart policies, based on actual costs.
We know that the adverse impacts of climate change are expected to slow growth and exacerbate poverty. An effective climate response is therefore not only an environmental necessity but an integral part of sustainable development.
Le ruissellement de l'azote dans l'agriculture menaçait les eaux limpides du lac Taupo - le plus grand et le plus emblématique lac de Nouvelle-Zélande - et d'endommager d'importantes activités économiques et culturelles. En 2011, le gouvernement régional a présenté des mesures de la qualité de l'eau, une expérience politique audacieuse et unique. Rapport disponible en anglais.
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.
D'ici 2050, les ressources disponibles en eau douce subiront des pressions accrues, 2.3 milliards de personnes de plus qu’aujourd’hui étant appelés à vivre dans des bassins hydrographiques soumis à un stress hydrique élevé. Allocution du Secrétaire général de l'OCDE, M. Angel Gurría : "Mettre la révolution de l'information au service de l'eau", Paris, le 21 Septembre 2015.
Making sense of and communicating data requires imagination and creativity. The bolder and more ambitious we are, the better we can produce, analyse and communicate policy-relevant data to support better water policies for better lives.
Le Forum est un lieu qui rassemble des experts des pays membres et des économies non membres afin de partager leurs expériences et d'explorer les questions de politique commune en se concentrant principalement sur la dimension environnementale du développement durable et de ses liens avec les politiques économiques et sociales.
