Global use of materials will increase from 85 to 186 billion tonnes per year by 2050
In the past 50 years deforestation has occurred at an average of 13 million hectares a year.
Material efficiency strategies can reduce emissions from materials and operational energy in housing by 40% in 2050 in G7 countries and up to 70% in India and China.
Global material resource use is expected to reach nearly 90 billion tonnes in 2017 and may more than double from 2015 to 2050.
About 25 per cent of the world's land is degraded.
Compact, resource-efficient cities could see cuts of 36-54 per cent in GHG emissions, and in metals, land, energy and water use.
Trade in material resources – biomass, fossil fuels, metals, and minerals – has increased by more than 90% in the past two decades.
Restoring 350 million hectares of degraded landscapes by 2030 could generate $US 9 trillion in ecosystem services and take 13-26 gigatons of greenhouse gases out of the atmosphere.
