In 2021, the Group withdrew 18.1 million cubic metres of fresh water, a 6% increase from 2020. Almost all (99%) of the water we used came from municipal water sources. Swire Coca-Cola withdrew the rest from groundwater sources.
Swire Coca-Cola accounts for the majority (86%) of the Group’s water use. It tracks the efficiency of its manufacturing process using the water use ratio (WUR) metric (litres of water used per litre of finished product produced) and aims to achieve a WUR of 1.45 by 2030. In 2021, its overall WUR was 1.81, a marginal improvement from 1.82 in 2020. Testing and commissioning new production lines in the Chinese Mainland, Hong Kong and Taiwan, and increased product variation impacted the water demand.
Swire Properties is the second largest water user, accounting for almost 10% of the Group’s water footprint in 2021. Water intensity at Swire Properties increased by 4.7% and decreased by 20.1% in its Hong Kong and Chinese Mainland portfolios respectively, compared to a 2016 business-as-usual base year. At its hotels, water intensity increased by 6.6% compared to a 2018/2019 levels. Overall, it used 1% more water in 2021 than in 2020.
