Studies show that cars use significantly more fuel per kilometre than suggested by official test ratings. This publication presents an analysis of the fuel efficiency gap and examines technologies available that could reduce that gap and improve fuel economy. It examines such areas as engine and...

Expanding markets for clean and efficient technologies will increase energy security and help reduce greenhouse gas emissions. But many promising technologies are still too expensive or face other obstacles to commercial deployment. Governments need to consider deployment policies to create...

This report identifies policy options and makes recommendations on market-oriented actions to promote the purchase of the most environmentally friendly vehicles. It assesses the impact of a wider use of low-emission vehicles, drawing on experience to date, research results and the responses to a...

"The European Conference of Ministers of Transport has released a report that analyzes the gap between fuel efficiency certification test ratings and the actual on-road fuel efficiency of automobiles. The report also examines technologies available that could reduce that gap and improve fuel...

Expanding markets for clean and efficient technologies will increase energy security and help to reduce greenhouse gas emissions. But many promising technologies are still too expensive or face other obstacles to commercial deployment. Realising the potential for a cleaner and more secure energy...

Buildings are the largest energy consuming sector in the world, and account for over one-third of total final energy consumption and an equally important source of carbon dioxide (CO2) emissions. Achieving significant energy and emissions reduction in the buildings sector is a challenging but...

The report brings together evidence, international experience and policy insights for the design of housing policies. Emphasis is placed on three broad aspects: inclusiveness, efficiency and sustainability. Inclusive access to housing has become increasingly challenging in many OECD countries...
