→ Continue to reduce absolute GHG emissions and expand initiatives globally, especially in renewable energy use → Continue to reduce waste generation from operations and maintain waste recycling at 50% or better KEY GOALS FOR 2022 Notes: 1. SGP: Material Singapore operations. 2. Scope 1: Direct GHG emissions from sources owned or controlled by the Group. 3. Scope 2: Indirect GHG emissions from the generation of purchased electricity consumed. 4. Scope 3: Indirect GHG emissions from business travel by air. 5. 2021 figures have been internally verified. ENVIRONMENTAL → Environmental Protection WATER CONSUMPTION AND CONSERVATION In 2021, our water consumption intensity decreased by 15% compared to the intensity in our 2015 base year. We introduced initiatives including a water harvesting pilot where we collected and reused rain water for aircraft washing at our hangars, and stepped up communication efforts to heighten awareness and shape behaviour towards water conservation. WASTE MANAGEMENT AND RECYCLING In 2021, our Singapore operations recycled 78% of 5,900 tonnes of waste generated. The recyclables included metal, wood, batteries and paper products.
