For the evaluation of environmental benefits, 10 products were selected from the list of 17 designated products/services for GPP. Using different methodologies such as; life cycle assessment, life cycle costing and others, NSTDA estimated the difference in impacts of conventional versus green products. In addition, it also established impact reduction coefficients per green product in terms of CO2 equivalent emissions reduction and environmental external costs reductions linked to energy use, waste management, operational costs, etc.
NSTDA calculated the estimated emissions and external
