Résumé

To what extent does digitalization of inputs decrease greenhouse gas emissions via efficiency gains? Taking an economy-wide perspective using inter-country input-output tables, as well as subnational input-output tables for the top three global emitters -- the United States, China, and India -- this paper estimates the impact of downstream sectors' adoption of digital inputs on greenhouse gas emissions. Using a shift-share instrumental variable strategy, we exploit productivity shocks among trading partners' digital sectors, as an identification strategy and reveal both substantial rebound effects and evidence that digitalization of inputs has unexpected adverse impacts on emission levels.
