This report highlights two underutilized but fully implementable technologies that efficiently integrate heat and electricity systems, provide flexibility and enhance energy security. It examines what restricts co‑generation and efficient district heating and cooling systems that can help de-carbonize the energy system.

With more than half the Earth’s population now living in urban areas, some changes in the indoor and outdoor climates of cities are bound to occur. Climate scientists’ greatest concern is traditionally the urban heat island (UHI) effect – city areas where temperatures can be several degrees higher because there is lots of concrete and little blue or green infrastructure like lakes, rivers and parks. But another effect – air flow – can also cause serious health problems.

Ramboll Environ developed an innovative, sustainable and economically beneficial approach to addressing the impact of metal contamination on river sediments in the River Nent in Cumbria.

This guide is about taking account of, and managing, ecosystems to help people adapt to climate change in coastal areas: coastal Ecosystem based Adaptation (EBA). Vital to human wellbeing, adaptation to climate change is increasingly important in international policy discussions such as the UN Framework Convention on Climate Change (UNFCCC) and Convention on Biological Diversity (CBD), which have acknowledged the potential importance of EBA in meeting this challenge.

This publication catalogues activities of the joint International Waters Programme between the United Nations Development Program and the Global Environment Facilty.
