4、zed chemical production in the United StatesZachary ByrumHIGHLIGHTS Reaching net-zero greenhouse gas(GHG)emissions will require tackling emissions-intensive sectors like chemical production,the highest-emitting U.S.industrial sector.“Defossilizing”chemicals by substituting fossil feedstocks with non
5、fossil feedstocks and energy carriers is a pathway that could achieve net-zero emissions when paired with other emissions-reduction strategies.Reducing chemical sector GHG emissions can also address environmental justice concerns such as adverse health impacts,particularly if accompa-nied by account
6、ability measures.Waste biomass,captured carbon dioxide(CO2),clean hydrogen(H2),and ethanol can be processed to create high-value chemicals with current or near-term technology.Although not yet readily available to meet current or future chemical demand,these technologies are likely to scale up in th
