Global petrochemical capacity keeps expanding, but the demand for cleaner performance is rising at the same time, and the figures reveal the tension. With 2023 ethylene capacity at 101.8 million metric tons and global petrochemical market growth projected at 4.9% CAGR from 2024 to 2030, capacity momentum is clear. Yet emissions benchmarks for steam cracking are still typically reported around 0.7–1.2 tCO2 per ton of ethylene and OECD projects plastics emissions could reach 3.4 GtCO2e by 2050, making the economics and environmental tradeoffs impossible to ignore.
