Abstract: Abstract This paper proposes the projected gradient algorithm to find a solution that allows economic restructuring to minimize carbon emission intensity and not hinder targeted economic growth. It develops a general formula to calculate how much each sector should change its share in gross domestic products and its emission intensity such that the economy can have a lower aggregate emission intensity without hindering economic growth. Used data for 30 nations during 1997–2009, the study indicates that if a country follows this proposed optimal restructuring solution, it experiences a lower carbon emission intensity than its initial scenario. This solution is helpful to (1) find the optimal direction and quantitative solutions of a low emission economic structure; (2) continuously check and quantify the differences between the optimal and actual directions of economic structuring for adjusting economic and environmental policies.
