How can technology help achieve the Paris Agreement goals of net zero emissions and limiting global warming? The Alestra et al. (2022) Advanced Climate Change Long-term Model (ACCL) is used to assess different scenarios of technological innovations and carbon taxation. Only a multi-lever strategy could reach the climate objectives.

Technology may significantly contribute to reaching the 2015 Paris Agreement goals of net zero carbon dioxide (CO2) emissions and global warming below 2°C in 2100. To test that, we use the Alestra et al. (2022) Advanced Climate Change Long-term Model (ACCL), particularly adapted to quantify the consequences of energy price and technology shocks. We assess a multi-lever climate strategy combining energy efficiency gains, carbon sequestration, and a decrease in the relative price of “clean” electricity with a rise in the relative price of polluting energy sources. None of these components alone is sufficient to reach climate objectives, but our composite scenario achieves the climate goals.

Climate policy has so far had limited results despite national commitments under the Paris agreement. Various scenarios establishing a cost-benefit balance of this policy bring to light the main obstacles it is facing. Its net gains are highly significant but remote in time and very unevenly distributed between countries.
