Switzerland has taken steps to improve the environmental performance of its agricultural, energy and transport sectors. The country is a top OECD performer in terms of greenhouse gas emissions intensity and it should be commended for its innovative approach towards rehabilitation of its river system. Yet unsustainable consumption patterns and high levels of municipal waste generation, as well as high percentages of threatened species, are areas of concern. As a major financial centre, Switzerland has a key role to play in promoting green finance. This is the third Environmental Performance Review of Switzerland. It evaluates progress towards sustainable development and green growth, with special features on: water management and biodiversity conservation and sustainable use.
