The objective of the project is capacity building for development of energy efficiency (EE) investment projects. It will assist UN Regional Commissions (RCs) to strengthen capacities of their member states to attract investments in energy efficiency projects in the context of climate change mitigation and sustainable development.While a number of countries worldwide have expressed their interest in adopting energy efficiency measures in sectors with high carbon dioxide emission levels, they still face serious challenges in attracting private investments in EE area. Capacity building for the development of energy efficiency investment projects is an essential requirement for this work. In addition, there are weak cooperation links between UN RCs in EE investment projects. UNECE experience combines technical assistance in design and implementation of investment projects, advice on policy and institutional reforms, and direct links with financial institutions (e.g. banks and investment funds) in order to establish mechanisms, which are able to fast-track the development of self-sustained markets for energy efficiency. The project will replicate this experience in other countries in different parts of the world through cooperation between the UN Regional Commissions, as well as cooperation within the UN-Energy framework.Through a close cooperation with the countries concerned and in the framework of a desirable investment framework, a series of interactive events and the use of local experts, the projects focuses of facilitating the increased mobilization of financial resources for energy efficiency measures.The project will (a) develop the skills of the public and private sectors at the national level to identify, develop and implement EE investment projects; (b) provide assistance to authorities to introduce regulatory and institutional reforms needed to support these investment projects; and (c) enhance financing of energy efficiency projects in selected countries.The project will provide case studies on the experience of policy reforms, regional trainings, workshops and seminars focusing on policy reforms and investment projects development The project builds on the UN experience and recommendations in the area of sustainable energy development and follows the work undertaken under the Financing Energy Efficiency Investments for Climate Change Mitigation (FEEI) project and other projects of the Energy Efficiency 21 (EE21) Programme. The proposed project will be implemented in cooperation with all UN RCs, other relevant UN agencies and national counterparts to strengthen their capabilities through a number of capacity building activities. While the project includes activities in policy reforms, the main focus will be capacity building for the development of energy efficiency investment projects.
