intensity of the nine largest steel producing countries and the EC-27.1 The curtailment of domestic steel production due to a coke supply shortage would make the U.S. dependent on imports of steel from countries where GIIG emissions from steel production arc substantially higher, not to mention the environmental emissions associated with shipping millions of tons of coke across the world. Domestic steel is a critical material for U.S. transition to a low-carbon economy.

SunCoke's patented heat recovery cokemaking process was recognized by EPA as the MAC-I. and the most environmentally friendly method to make coke.' SunCoke's unique cokemaking process creates higher quality, higher strength coke that results in steelmakers using less coke in their blast furnaces and thereby lowering their GIIG emissions; in this way, SunCoke supports steelmakers in achieving their GHG-reduction SunCoke invests in maintaining and improving its cokemaking plants to ensure they arc performing optimally and in compliance for decades to come. With its environmentally superior technology and younger cokemaking assets,' SunCoke is well positioned to be a leader in producing coke for the domestic steel market for many years to come. SunCoke's Jewell facility also began producing foundry coke in 2021 after making a S50 million investment to refurbish its coking facility in Vansant, Virginia.
