Sanfield, SHKP's construction arm, launched the 2024 Environmental Day on 10 October to encourage colleagues to go green in both the workplace and everyday life. On the event day, Sanfield organized a series of activities, including reusable goods donation and exchange, a vegetarian lunch and a half-hour lights-out session.

This marked the third edition of Sanfield Environmental Day, which was initiated to support Hong Kong's Climate Action Plan 2050. In 2022, Sanfield stopped distributing disposable plastic utensils, opting instead for reusable titanium cutlery for its staff. The company also set up recycling bins at various construction sites to promote clean recycling and a greener workplace.
