Launch of Go 25 national movement

25 June 2025

On 16 May 2025, the Ministry of Sustainability and the Environment (“MSE”) issued a press release announcing that the Singapore Green Building Council (“SGBC”) and MSE, supported by the National Environment Agency (NEA) and Building and Construction Authority (“BCA”), have officially launched Go 25 to encourage sustainable cooling, by setting indoor air-conditioning at (or above) 25°C. This was announced by Senior Minister of State for Sustainability and the Environment Dr Amy Khor in her speech at the launch of Go Green SG 2025, Singapore’s national sustainability movement. 

Key initiatives under Go 25 

As part of the Go 25 movement, there will be a series of initiatives and activities to raise awareness on sustainable cooling best practices, and to support businesses and building owners. 

Go 25 Pledge 

The Go 25 Pledge is a voluntary industry commitment to sustainable cooling. Under this initiative, building owners, businesses, and organisations commit to: 

  • setting indoor temperatures at 25°C or higher, or as close to 25°C as possible if it cannot be achieved without compromising comfort due to infrastructural constraints; 
  • adjusting temperature gradually to ease transition for occupants; 
  • providing alternatives such as fans and encouraging relaxed dress codes; 
  • displaying indoor temperatures and promoting the pledge publicly via a downloadable Go 25 Toolkit (includes poster templates, social media assets, and infosheets). 

The Go 25 Pledge creates a platform for Singaporeans to commit to energy-efficient cooling practices. 

Go 25 Industry Guide 

A Go 25 Industry Guide will be published in the third quarter of 2025 to help facilities managers and building operators implement higher indoor temperatures on their premises. Developed by SGBC and BCA, the guide will serve as a technical reference for the process and considerations needed when raising indoor ambient temperature, while maintaining occupant comfort.
