ConclusionsConclusionsConclusionsConclusionsPotential energy & emissions savings via catalysis in the gy g ychemical segment vs. a “do nothing” case of 12 EJ/yr and 0.86 Gt CO2/yr by 2050 (incremental + BPT scenarios)Full implementation of Best Practice Technology could improveFull implementation of Best Practice Technology could improve energy intensity per ton of product by as much as 40% by 2050. While these energy savings are sizeable on an absolute scale, expected production increases globally will likely outpace these savings and overall energy and GHGs will likely increase Reducing energy use or GHG emissions by half or more by 2030 or 2050 does not seem realistic even in developed regions with lower growth such as Europeregions with lower growth such as Europe . Gamechangers could yield additional reductions in GHGs, but would increase energy use and require huge investments to
