To drive progress toward carbon neutrality, Avient’s low carbon transition plan targets intermediate (2030) goals around Scope 1 (direct) and Scope 2 (indirect) sources of greenhouse gas emissions. Most of Avient’s Scope 1 and 2 GHG emissions are attributed to the consumption of energy. Scope 3 emissions are many times greater than our combined Scope 1 and 2 emissions.
