Junior college, Institute of Technical Education and polytechnic students should start with the official Clean & Green Singapore Sustainable Cities Challenge page. It identifies the eligible institution types and links to the detailed 2026 challenge microsite.
The 2026 tertiary edition used the theme “Designing Circular Cities” and invited teams to choose sustainable fashion or responsible food production. The linked microsite carries the proposal framework, rules, entry route, roadmap and next-stage information.
The microsite reviewed on 21 October 2026 says preliminary submissions closed on 24 August 2026 and the edition is officially closed. Shortlisted finalist teams are contacted directly by email, so a past entry form is not a route for a new team or a later cycle.
Find your next step
Which sources own the challenge information?
Clean & Green Singapore provides the official programme-level route under the Youth for Environmental Sustainability movement. The linked organiser microsite owns the detailed task, team format, rules, submission status and finalist process. A school notice may explain local coordination, but it should not be used to infer eligibility or deadlines for another institution.
| Your question | Best source | What to verify |
|---|---|---|
| Who is the challenge for? | Clean & Green Singapore page | Eligible institution types and current programme route |
| What is the current task? | 2026 challenge microsite | Theme, chosen sector, proposal expectations and team size |
| What rules apply? | Rules and proposal framework linked on the microsite | Evidence, format, originality, judging and submission conditions |
| What happens after submission? | Microsite status and organiser email | Closure notice, finalist contact and next-stage instructions |
What should a team check first?
1. Confirm the institution category
The government page describes the tertiary challenge as open to students from junior colleges, polytechnics, ITE and equivalent institutions in Singapore. That is an eligibility description, not proof that an individual entry was accepted. Check the current rules and ask the institution’s coordinator how teams are registered or endorsed.
2. Read the cycle status before using any form
The 2026 preliminary deadline has passed and the microsite labels the edition closed. Students who did not submit should not send materials through an old form. Finalists should follow the direct email instructions, while future teams should monitor the government page for a new cycle.
3. Match the proposal to one task
For 2026, teams of two to four selected either a fashion-apparel category or a food-production sector. The proposal needed practical, scalable improvements with evidence about environmental impact and resource efficiency. Mixing both tracks or offering slogans without analysis would not answer the stated brief.
4. Keep calculations and claims traceable
A sustainability proposal may discuss carbon, water, waste, sourcing, packaging or resilience. Record where each figure came from, state assumptions and distinguish a measured result from an estimate. The official framework and rules—not a past winning project—should decide the required format and evidence.
A practical next step
If your team entered the 2026 cycle, check the organiser email address used in the submission and follow only verified finalist instructions. If you missed the deadline, save the government page and build a small evidence file on one production system while waiting for a new official notice.
Use eduKate’s Singapore School Pathways and Calendar to place the opportunity alongside JC, ITE and polytechnic commitments. The official source-guides directory provides other source-first routes without treating competition participation as an admissions guarantee.
