There is still no international comprehensive methodology to assess on the environmental impact of ICT at a sector level, as well as to assess on the aggregated positive effect of the ICT sector in other sectors of the economy. Without a standard methodology evaluating the positive impacts of ICT, the role of ICTs in the fight against global warming will be only partially perceived. This Recommendation addresses the need to contribute to achieve the targets and goals of the 2030 Agenda for Sustainable Development, specially its Sustainable Development Goal 13 (SDG13), the Connect 2020 Agenda, and the Paris Agreement from a global perspective This Recommendation adresses the opportunity to use a computable general equilibrium (CGE) model as a possible methodology for simultaneously assessing the environmental and economic impacts of ICTs at sectoral level.
