Variable frequency drive retrofits on ethylene glycol pumps, chillers, air compressors, and ventilation systems at Changshu, Taixing, Jinshan, Waigaoqiao, Couvet, and Wuxi sites expected to save ~4,937 MWh electricity and 3,890 tonnes of steam annually. Waste-heat recovery installed on air compressors and chiller units at Changzhou, Suzhou, Nantong, and Couvet expected to save ~2,585 MWh electricity and 19,104 tonnes of steam annually.

sustainability_report p.58

Purchased goods and services account for over 80% of Scope 3 emissions, making raw material decarbonization the key pillar of WuXi AppTec's 2030 Scope 3 target. Established tiered supplier management classifying suppliers by carbon performance with differentiated reduction requirements. Collects primary site-level emissions data from a subset of significant suppliers; engaged 21 significant suppliers in carbon management collaboration in 2025. Gradually incorporating product/service carbon footprints into supplier evaluation.
