District energy in cities - Unlocking the potential of energy efficiency and renewable energy
This report by the United Nations Environment Programme (UNEP) prepared in collaboration with the Copenhagen Centre on Energy Efficiency (C2E2), ICLEI – Local Governments for Sustainability and UN-Habitat, provides an overview into what integration and systems thinking look like in practice when addressing challenges in the energy, transport, buildings and industry sectors and showcases the central role of cities in the energy transition. The document provides concrete policy, finance and technology best practice guidance on addressing the heating and cooling sectors in cities through energy efficiency improvements and the integration of renewables. It offers an in-depth review of 45 cities around the world, providing a platform for further global expansion of district energy approaches across cities worldwide. It aims to serve as guidance for accelerated implementation and expansion of district energy systems through a “cities -for- cities” thematic twinning process. The report highlights why and how cities are deploying district energy systems, including by demonstrating key policy best practices, new business models and emerging innovations. It also consolidates data on the multiple benefits that cities, regions and countries have achieved from a transition to modern district energy systems including greenhouse gas emissions reductions, air pollution reductions, energy-efficiency improvements, use of local and renewable resources, resilience and energy access and green economy.
Low-carbon cities worldwide have been surveyed to identify the key factors underlying their success in scaling up energy efficiency and renewable energy, as well as in attaining targets for zero or low greenhouse gas emissions. District energy systems (DES) emerged as a best practice approach for providing a local, affordable and sustainable energy supply, improve energy efficiency and support energy access efforts. They represented a significant opportunity for countries and cities around the world to move towards climate-resilient, resource-efficient and low-carbon pathways.
