Operational excellence – a lever to continuously increase our energy efficiency and avoid CO emissions 2 Reduction of CO emissions through operational 2 excellence measures  Opex measures helped to reduce CO emissions Kilo tons per year, cumulative 2 by ~1 million tons from 2013 to 2021 1400  In 2021, ~400 opex measures were realized that reduced CO emissions 1200 2  Examples: 1000 − Plant for plastics production repurposed 800 off-heat to generate steam for other plants, equaling ~5,000 tons lower CO emissions annually 2 600 400 − Further optimized process control in nitric acid cluster avoids 145,000 tons of CO2 200 equivalents per year  New process to foster opex projects linked to 0 CO emission reductions 2013 2014 2015 2016 2017 2018 2019 2020 2021 20221 2 20 December2022 | BASF ESG Investment Story 1 Forecast
