Wuxi Apptec

Carbon per million dollars of revenue. The legacy industry-standard reference (CDP, MSCI). Useful for cross-sector context, but distorted by margin — high-margin firms appear artificially efficient. Read alongside the operational and asset intensities for the full picture.

OpEx (operating expenditure) is the running cost of the business — staff, services, energy, materials. This shows how carbon-intensive operations are per million dollars of spend. Removes the margin distortion that revenue-based ratios introduce.

EVIC (Enterprise Value Including Cash) is the firm's total capital footprint — equity + debt + cash + minority interest. The EU's standard intensity measure (SFDR PAI 3) — answers: how much carbon does each million of capital deployed in this business produce?

PP&E (Property, Plant & Equipment) plus leased real-estate assets is the firm's physical infrastructure on the balance sheet. This shows the carbon intensity of that physical footprint — uses Scope 1+2+3 for consistency with the other headline intensities. Surfaces stranded-asset risk for asset-heavy firms.

In 2025, WuXi AppTec procured 297,961.70 MWh of renewable electricity and generated 4,061.06 MWh from on-site photovoltaic systems, representing 34.21% of total operational electricity consumption. Distributed photovoltaic systems are installed at Couvet, Jinshan, Taixing, Wuxi, Suzhou, Wuhan, and Nantong sites on rooftops and carports. The Wuxi site is additionally equipped with energy storage systems enabling self-consumption with surplus power regulation. Existing PV reduced carbon emissions by about 2,475 tonnes during the reporting period.

The Company does not currently plan to use carbon credits to offset greenhouse gas emissions for the purpose of achieving any net greenhouse gas emissions target. Decarbonization strategy relies on absolute emissions reductions through energy efficiency, renewable energy transition, low-carbon design, and supplier collaboration rather than offsets or removals.

• On-site renewable generation expansion

  Continues to expand distributed photovoltaic systems at qualifying sites with rooftop solar and carport installations across seven main sites. Wuxi site has energy storage integration. 2025 generation: 4,061.06 MWh, avoiding ~2,475 tCO2e.

• Green chemistry: continuous manufacturing and enzyme catalysis

  Continuous manufacturing platform supports 60+ reaction categories across 35+ lines; in 2025 supported 150+ customers across 600 steps producing 650+ tonnes of compounds, with cumulative waste reduction of 8,000+ tonnes. Enzyme catalysis platform with 3,500+ enzymes reduces organic solvent usage by >90% vs traditional chemical routes; in 2025 reduced organic solvent use by ~2,000 tonnes across 100+ projects.

• Energy efficiency: equipment upgrades and waste-heat recovery

  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.

• Supply chain decarbonisation - purchased goods (Scope 3 Cat 1)

  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.

• Supplier capability building and low-carbon training

  Provided 1,282 hours of sustainability training to suppliers in 2025; 66 significant suppliers participated in the empowerment program. Conducted climate capability-building training with significant suppliers to align operations with WuXi's SBTi-validated targets.
