Which ministry unveiled a draft 'Nation Resource Efficiency Policy'?

In order to save the natural resources, the Union environment ministry unveiled a draft 'Nation Resource Efficiency Policy' which suggests the institutional mechanism and a three-year action plan through the principle of 6R and 'green public procurement'. In India, the consumption of fossil fuels, biomass, metal ores and non-metal ores was increased by over 6 times in 45 years, from 1.18 billion tonnes (BT) in 1970 to 7.4 BT in 2015. It is projected to be doubled by 2030 from 2015 level. The 6R stands for Reduce, Reuse, Recycle, Redesign, Re-manufacture and Refurbish. It is to procure products with lower environmental footprints such as secondary raw materials and locally sourced materials. The draft suggests to set up 'National Resource Efficiency Authority' (NREA) to develop an action plan with 3 years time-frame, create and maintain database, measure progress and build capacities.
