Guided tour at Sentosa, textile recovery workshops among activities in Go Green SG 2026 line-up

SINGAPORE – Sentosa, which draws throngs of visitors to its attractions and sandy beaches, will be shining a spotlight on its biodiversity in May and June.

The public can sign up for a free guided tour to learn about the southern island’s unique wildlife and conservation efforts at the Sentosa Nature Discovery gallery, which also sports a replica of a military bunker that is home to the largest known colony of swiftlets in Singapore.

The new guided tour, held by Sentosa Development Corporation (SDC) in collaboration with the National Environment Agency (NEA), will also introduce participants to the cooling measures installed around the island.

For instance, cool nodes are being rolled out across Sentosa over the next few years, providing visitors with pit stops to seek respite from the heat. Each cool node has different cooling features, such as shades, fans and heat-reflective paint that can reduce surface temperatures by up to 2 deg C.

Visitors on the tour will also explore sustainable practices employed by Siloso Beach Resort and visit its wormery – a small outdoor shed housing 100 trays of earthworms that turn the eco-resort’s food waste into 300kg of fertiliser each month.

The guided tour of Sentosa’s sustainability and conservation efforts is just one of many activities that will be taking place during the 2026 edition of Go Green SG, an annual movement led by the Ministry of Sustainability and the Environment (MSE) to rally citizens, businesses and the community to take collective action towards a more environmentally sustainable and climate-resilient Singapore.

Go Green SG 2026 will run from May 11 to June 28, and feature more than 1,000 activities organised by around 500 partners, with some initiatives on raising awareness of climate change.

MSE has designated 2026 as Singapore’s Year of Climate Adaptation, signalling the need for climate action as a national priority as the Republic feels the impacts of climate change, such as hotter weather and the threat of rising sea levels.

“It’s important for the public to know what climate adaptation is about and how it is relevant to them,” said Ms Gloria Tan, director of NEA’s 3P (people, public and private) Network Division.

“The guided tours provide a hands-on experience for everybody to go through because explanations in classrooms can only do so much, but seeing is actually believing.”

SDC’s director of sustainability Anthony Tan said: “Sustainability is a very wide topic and very often people will focus on carbon emissions. But as custodians of the island, it’s important for us to be comprehensive in our approach, looking not just at decarbonisation, but also the protection of our natural and historical heritage.”

Go Green SG began as Climate Action Week in 2019 and was rebranded in 2023 to reflect growing interest and partnership among the 3P sectors and Singaporeans. The 2025 edition of Go Green SG saw more than 232,000 people taking part in over 900 activities.

Other activities taking place in the 2026 edition include learning journeys to an energy-from-waste plant on Jurong Island, escape room-style workshops by the Singapore Fashion Council about the fashion industry, and tours by the Earth Observatory of Singapore highlighting issues such as rising sea levels and the real-world applications of research.

Members of the public can also sign up for new exclusive activities, such as a behind-the-scenes tour of fashion social enterprise Cloop’s sorting facility.

Launched in 2020, Cloop aims to tackle the problems of textile waste and overconsumption in Singapore. The social enterprise organises clothing swops for shoppers who can also buy pre-owned clothes. It also manages textile donation bins here for people to drop off pre-loved clothing, accessories and plush toys.

This is the first time Cloop’s sorting facility will be opened to the public. Visitors can lend a hand in sorting donated clothing for repair, reuse, upcycling and recycling, while getting a glimpse into the realities of recycling textiles in Singapore.

The facility receives around 1,000kg of donated textiles weekly, collected from bulk donations and its white collection bins, which are specifically for items in good condition.

Participants will also learn tips on how they can adapt to the heat through their fashion choices, such as picking clothes made of natural materials like linen and cotton, which are better suited to Singapore’s climate. The activity is priced at $8 for children aged six to 12 and $15 for adults.

As Singaporeans experience the thinking process and laborious work behind the scenes, Cloop co-founder Jasmine Tuan hopes that more of them will be inspired to not just donate and recycle their unused or unwanted clothes, but also practise mindful consumption.

“A lot of people aren’t aware of what happens after they donate their clothes. After they donate, it’s out of sight, out of mind, and then they might shop for new clothes again,” she said. 

“We feel that there’s a gap in awareness that we haven’t filled among the public who use and know our recycling bins,” she added.

“There are uncertainties about where the clothes go after being put into our bins,” Ms Tuan said.

“Through Go Green SG, we want to empower the community to be part of the solution.”

The public can visit www.gogreen.gov.sg to browse the activities held during Go Green SG 2026. Online registration for activities will begin from May 8.

Correction note: In an earlier version of the story, we said that members of the public can choose from more than 1,000 activities. MSE has clarified that not all activities will be open to the public.
