Resource Efficient Housing programme is being piloted with Burkina Faso and Sri Lanka as the first 2 selected countries. The programme responds to the urgent need to reduce global greenhouse emissions with a focus on material resource efficiency, given the fact that 50% of the building stock is yet to be built, with most of it to occur in developing countries. The main objective is to support countries building their roadmap towards a resource efficient, low carbon and climate resilient buildings strategy.
