- GC has set the target to reduce water consumption intensity by 10 percent, based on Business as Usual (BAUs), within 2023 compared to base year (2013)
- Halve dependence on current water sources by 2032
Challenges and Opportunities
GC’s production process may be susceptible to the risk of water shortage due to climate change, which may result in business disruption. Moreover, changes in policy and regulation may impact production costs. Therefore, GC has worked closely with networks, government agencies, industries, water users, communities, and all stakeholders to collectively achieve efficient and sustainable water management. The company systematically monitors internal and external water usage and regularly assesses the quality of effluent to ensure that the quality of water discharged from its operations is safe and meets required legal standards.
