ST Engineering Sustainability Report 2020

CORPORATE OVERVI EW PERFORMANCE REVI EW SUSTAINABI L ITY CORPORATE GOVERNANCE F INANCIAL REPORT Reducing Engine Test Cell Fuel Consumption Aircraft engine testing consumes a large quantity of fuel and contributes significantly to both operating costs and our carbon footprint. Our engineers embarked on several initiatives to reduce fuel consumption for CFM56 engine testing since 2016, including adjusting the Single Run Multi-Thrust rating, optimising the trimming of the vibration fan and reducing oil use per run. These continuous improvements have reduced fuel consumption by 20%. GHG Emissions and Intensity Water Consumption and Intensity (SGP) Waste Recycled (SGP) 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. GHG emissions intensity figures are computed based on Scope 1 and 2 emissions. 6. 2020 figures have yet to be audited. 7. GHG emissions figures are normalised using Group revenue. 8. Water intensity figures for Singapore operations are normalised using revenue from Asia, of which Singapore is a significant contributor. 81 ANNUAL REPORT 2 0 20 / 0 0.20 0.15 0.10 0.05 0.00 1200 900 600 300 Water Consumption Intensity ('000m 3 ) Intensity ('000m 3 /$m) 0 200 20 15 10 5 0 150 100 50 Intensity Scope 1+2 Scope 3 ('000t)CO 2 e Intensity (tCO₂e/$m) Metal Paper & Carton Electronic Waste Wood, Crates & Pallets Tyres Waste Oil Batteries 34.1% 45.3% 1.8% 0.9% 15.2% 2.4% 0.3% 2018 2020 2019 125 122 111 0.3 11.2 12.4 18.6 15.5 15.5 2018 2020 2019 664 656 717 0.14 0.13 0.16
