Initiated by the detection of the so called “ozone hole” over the Antarctic, the Montreal Protocol on Substances that deplete the Ozone Layer came into force in 1987. The Protocol regulates the phase-out of production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFC) in refrigeration and air conditioning. This phase-out has led to the introduction of new, environmental-friendly technologies in industrialized countries.

This publication examines the sectors, technologies and policy measures that will be central in the transition to a low-carbon energy system. It addresses the following questions: (1) What are the roles of coal and gas in meeting the stringent decarbonisation requirements for the power sector consistent with IEA modelling of global climate goals? (2) What are moderate carbon prices accomplishing in the electricity sector, and how can they be helpful as part of a package of other policies?

RenoValue is a 2-year project funded by the Intelligent Energy Europe Programme of the European Union. The project will develop a training toolkit for property valuation professionals on how to factor energy efficiency and renewable energy issues into valuation practices, understand the impact of building performance and property values and advise their clients accordingly.

Developed by the United Nations Environment Programme (UNEP), the Cleaner, More Efficient Vehicles Tool provides information and real-world examples of technology and policies used around the globe to improve auto fuel economy.
