What is the Diploma in Environmental Science & Sustainability about?

The Diploma in Environmental Science & Sustainability (ESS) is for you if you want to fight climate change and build a more sustainable future. ESS equips you with the scientific, engineering and digital skills to turn sustainability goals into real-world solutions – from managing water and resources to reducing pollution and waste, and supporting a circular economy.

You will also learn to harness emerging technologies such as data analytics, Internet of Things (IoT), artificial intelligence and machine learning to to develop smarter, more sustainable solutions to environmental challenges.

How will you put your learning into practice?

See sustainability in action through field trips and learning journeys to places such as Bishan-Ang Mo Kio Park, NEWater plants and the Sustainable Singapore Gallery. Apply your skills in hands-on projects using IoT sensors and drones for environmental monitoring.

In your final year, you may opt for a one-year internship for deeper industry exposure with PUB, Singapore’s National Water Agency. Alternatively, tackle a real-world environmental challenge through a capstone project, followed by a six-month internship with partners such as Sembcorp, Xylem Water Solutions, Marchwood Laboratory Services and NP's Centre for Environmental Sustainability (CfES).

What other opportunities does the course offer?

Build your skills and strengthen your portfolio through competitions and programmes such as WorldSkills, the Xylem Global Student Innovation Challenge and the NEA YES Leaders Programme.

You can also enhance your career prospects with additional certifications in bizSAFE Level 2, noise monitoring and noise control, equipping you with credentials relevant to safety, environmental and sustainability roles.

Can you get a head start in university?

Yes! Get a university head start through the NP-NUS or NP-NTU Pathway, available to selected students. You can take university-level modules while studying at NP, which may count towards your degree later and help you fast-track your studies.

What scholarships are available?

You may be eligible for a bond-free PUB scholarship, which includes an internship placement and the opportunity to vie for the Singapore Sustainability Scholarship. The NEA-Industry Scholarship also offers a $15,000 annual study award and employment with a sponsoring company.
