- Global inflationary pressures, coupled with the industry chain's active consumption of excessive inventory, have dealt a blow to the recovery of end-market consumption, further slowing down the pace of inventory destocking
- intense global industry competition and threats
- Global climate anomalies leading to water shortages and operational disruptions due to heavy rainfall
- Increased pricing for greenhouse gas emissions
- Strengthened emissions reporting obligations
- Requirements for and oversight of existing products and services
- Substitution of existing products and services with low-carbon alternatives
- Costs of transitioning to low-carbon technologies
- Changes in customer behavior
- Changes in rainfall patterns and in extreme climate patterns
