Abstract The United States has achieved economic growth compatible with carbon reduction since 2007. This work is addressed to understand the eight effects, especially effects related to research & development (RD whereas economic scale was the primary inhibitor to the drop of carbon emission, followed by investment intensity, population size and sectoral energy structure. The results of decoupling efforts analysis uncover that energy intensity, R&D intensity, R&D efficiency and sectoral carbon intensity contributed to decoupling economic growth from carbon emission, whereas investment intensity, population size and sectoral energy structure did not contribute to the decoupling. Finally, some policy implications are proposed.
