Guided ferry tour of Southern Islands, mushroom cultivation among activities in Go Green SG 2025
SINGAPORE – Despite being the world's second-busiest container port after Shanghai, with a national record of 3.11 billion gross tons in arriving ship traffic in 2024, Singapore and its waters remain hospitable to a variety of marine and coastal wildlife.
The Republic is home to a third of the world's hard coral species, half the number found in Australia's Great Barrier Reef – the world's largest coral reef system.
In an exclusive and informative guided tour by the Maritime and Port Authority of Singapore (MPA), visitors will be introduced to the maritime ports of mainland Singapore and its Southern Islands.
This is just one of over 900 activities organised by the Ministry of Sustainability and the Environment (MSE), together with some 400 partners from across the people, public and private sectors, for Go Green SG in 2025 .
There will be external activities for the public to partake in and internal ones conducted in schools and organisations. The aim is to rally the populace to make Singapore a green, liveable and climate-resilient nation.
Among the activities are a mushroom cultivation workshop by Mushroom World Academy held at Vidacity , tours of the Solar Energy Research Institute of Singapore – the island's first inland floating solar farm – and upcycling workshops by Kong Wai Shiu Hospital. An adaptive reuse of the now-defunct Loyang Primary School, Vidacity is a hub for sustainability and agri-tech start-ups, social enterprises and innovators from tertiary institutions and the community.
First launched as Climate Action Week in 2020, the annual affair was revamped into a month-long campaign and rebranded as Go Green SG in 2023, after MSE saw growing interest in sustainability efforts among the public.
This third edition will be launched by President Tharman Shanmugaratnam at Changkat Primary School on May 16, and will run till June 29.
As it partially overlaps with the school holidays, families with children can participate in the activities during and outside the school term.
The 2024 Go Green SG campaign saw more than 50,000 people take part in over 400 activities, said MSE.
With 2025 marking 60 years of Singapore's independence, Go Green SG will feature sustainability-related activities highlighting the nation's progress in environmental efforts over the years, as well as intergenerational bonding.
MPA Sea Exploration Tour
Showcasing Singapore's maritime sustainability and decarbonisation efforts, the tour begins at the Singapore Maritime Gallery at Marina South Pier.
Visitors will be introduced to Singapore's rich maritime history and heritage through videos, models of ships and buildings like the five lighthouses of Singapore and its ports, and artefacts of navigation tools and ship parts still in use today.
A new maritime heritage zone was also recently curated to showcase archaeological artefacts found within Singapore's waters, and its maritime legacy that well precedes its colonial history.
A highlight is a repurposed 20-foot equivalent unit shipping container that has been converted into an exhibition area illustrating Singapore's evolution from manually transporting goods via gunny sacks to containerisation – the transport of large quantities of items in containers.

According to tour guide Grace Christine, one 20-foot equivalent unit is able to transport almost anything, with enough space to carry up to 48,000 bananas, for instance.
'Containerisation is historically significant to Singapore, because in the 1950s no other countries in our region were practising it. We were the first. Today, we are connected to more than 600 ports around the world,' she said.
An hour-long ferry ride will then take participants along Singapore's southern coast to observe port operations and maritime activities, before touring some of the Southern Islands, including Pulau Tekukor, Pulau Bukom, Pulau Semakau and Pulau Jong – which at low tide exposes a coral reef six times the size of the island itself.
The ferry bypasses Jurong Island and Pulau Sebarok, which is home to many industrial chemical and energy facilities. Participants will hear about Singapore's green energy and decarbonisation efforts from the tour guides.
Participants will disembark at Large Sisters' Island to tour the recently revamped island. Since its reopening in October 2024, it has featured signages to educate visitors of its rich biodiversity. Some of the fauna found here include the lesser dog-faced fruit bat, kingfisher, brahminy kite, Haddon's carpet anemone, flower crab, tuskfish and reef shark.
Mushroom cultivation workshop
Participants will learn how to cultivate mushrooms using recyclable materials during a workshop conducted by World Mushroom Academy.

The workshop by Mushroom World Academy offers participants a hands-on experience at growing their own edible fungi using recyclable materials.
The academy conducts workshops for the public to learn how to grow a variety of mushrooms using recyclable materials in the comfort of their homes. It also partners educational institutions like Ngee Ann and Republic polytechnics to further its research and development efforts.
'The final product is an edible and delicious mushroom that serves as excellent protein alternatives... The mushroom that participants will cultivate in this workshop is the milky mushroom, which is commonly used in masala (an Indian spice blend) ,' said academy founder William Leong.
Milky mushrooms grow well in hot and humid climates, making cultivation in South-east Asia ideal, according to the academy. It has a nutty flavour with a 'meat-like bite' and is most suitable for stir-fries, curries and grilling.
In the two-hour workshop, participants will be introduced to the basic science of mushroom anatomy, and the significance of waste in Singapore, in particular, cardboard waste.
Cardboard is an excellent organic matter that offers mushrooms the necessary nutrients to grow since it has no chlorophyll and cannot produce energy from the sun. Understanding the extent of cardboard waste in Singapore and food insecurity globally, the people in the academy came together with a dream of tackling two issues with one stone – or rather, one cardboard.
According to the National Environment Agency (NEA), Singapore generated over 1.2 million tonnes of paper and cardboard waste in 2023 but only recycled 31 per cent of it. Globally, famine affects over 200 million people today, noted the World Bank Group.
Participants will learn how to create the substrate – a combination of wet, shredded cardboard, sawdust, a nutrient mixture to activate and expedite the growth of the mushrooms, and compost – which will bury a mushroom fruiting pack containing the fungi's mycelium, the vegetative part of the fungus, akin to that of a plant's root system.
The substrate offers the mycelium an ideal environment to grow into mushrooms. This process takes about three to four weeks.
Once the white mushrooms are harvested, the substrate mixture can be reused as compost in its entirety, and if needed, the sawdust used can be extracted and repurposed in subsequent yields of mushrooms.

Other mushrooms the academy has successfully cultivated using recyclable materials include the termite mushroom, wulingshen mushroom, tiger milk mushroom, lion's mane mushroom and even lingzhi mushroom, a popular medicinal mushroom used in traditional Chinese medicine.
'Our focus is on educating the public about the importance of sustainability and food security through our educational programmes... According to the NEA, Singapore has an ever-increasing rate of cardboard use. So we want to show Singaporeans a way to reuse their cardboard waste,' Mr Leong said.
The public can go to the Go Green SG website on to check out the activities. Online registration for activities starts from May 12, with more being released gradually across the Go Green SG period.
Here are some other activities.
