The need for real estate to provide a positive social and environmental impact has never been so pressing: according to the World Business Council for Sustainable Development, buildings account for up to 40% of energy use in most countries.

Too few developers and investors are providing the right buildings consistent with the COP26 and UN targets on global warming and sustainable development. They need encouragement, and one of the big changes that could help bring this about is the introduction of a consistent valuation methodology related to green and sustainable metrics.
