Sustainability: The Key To Our Future

Green, eco-friendly, natural — these words surface in our daily lives as people become increasingly environmentally conscious. But in today’s world, sustainability is no longer a buzzword; it’s a necessity.

The path to a sustainable future calls for collaboration — between governments, businesses, and individuals. But translating commitment into action often requires expertise that many organisations don’t yet have. That’s where environmental and social consultants come in — bridging the gap between good intentions and responsible impact.

To better understand the role, we spoke with Claudia Tan, an Environmental and Social Consultant and a current postgraduate student at Newcastle Australia Institute of Higher Education, where she is pursuing her Master of Environmental Management and Sustainability (MEMS).

Changing the World, One Project at a Time

As an Environmental and Social Consultant at Mott MacDonald Singapore Pte Ltd, Claudia helps businesses and banks navigate the complex frameworks that guide sustainable development — including the Equator Principles 4 (EP4).

These frameworks, often shaped by global financial institutions like the International Finance Corporation (IFC) or the Asian Development Bank (ADB), ensure that projects account for both environmental and social risks. In many cases, aligning with these standards can also help businesses secure project financing while minimising environmental and social impacts. 

Most days, Claudia is deep in reports and technical documents — assessing compliance, offering expert recommendations, and supporting project teams. Some days takes her out of the office, where she conducts on-site visits, checks on progress, and provides hands-on technical guidance.

Bit by bit, project by project, Claudia’s work contributes to a future where sustainable development is not just viable — but responsible and inclusive.

A Journey Fueled by Passion and Purpose

Claudia’s commitment to sustainability can be traced back to her earliest memories. Inspired by National Geographic shows and science books gifted by her parents, she developed a fascination with the natural world that only grew stronger over time.

That passion crystallised during her time in New Zealand, where the sheer beauty of the landscape deepened her resolve to protect it. “These unforgettable memories fuel my determination to preserve nature’s beauty,” she reflects.

Her first taste of consulting came through an internship, which led her to pursue a full-time role after graduation. Wanting to sharpen her expertise, Claudia enrolled in the MEMS programme at Newcastle Australia— a course that provided her with practical skills in environmental management, policy frameworks, and sustainability strategies.

“The course modules are very relevant to what I do on a daily basis,” she shares.

Even with passion as her compass, the role came with challenges. Claudia recalls a particularly tough assignment early in her career that tested her ability to anticipate client needs and adapt in real-time. “It was a steep learning curve,” she says. “But those early experiences shaped my confidence and equipped me with skills I still utilise, up till today.”

From Paperwork to People

While the technical reporting aspects of Claudia’s role bring her great fulfilment, it’s the human stories that have left the deepest impact. One standout experience took her to Vietnam, where she helped ensure that landowners affected by a project received fair compensation.

“It was really meaningful,” she shares. “I had to meticulously investigate every detail of the acquisition, and check for appropriate stakeholder engagements to ensure the standard of living for those affected wasn’t just maintained — it was improved.”

Experiences like these remind Claudia of why she chose this path: to ensure that sustainability includes not only environmental stewardship, but social justice too.

Building a Climate-Conscious Community

In Southeast Asia, the impact of climate change is no longer abstract. The 2024 heatwaves set new records for the highest temperatures and heat indices throughout the region. “Extreme weather patterns outside of the Milankovitch cycles, or typical warming and cooling cycles of the Earth are nature’s way of sounding the alarm,” says Claudia.

The growing awareness of climate change is pushing individuals and organisations to rethink their role in the climate crisis. Claudia encourages businesses to look toward the United Nations’ 17 Sustainable Development Goals (SDGs) as a roadmap for meaningful action.

“If you’re not sure where to start as an individual, begin small,” she advises. “Recycle and cut back on single-use plastics. Opt for energy and water-efficient appliances. Do your own research on actions the individual can take. Even small changes add up when done collectively.”

Still, she acknowledges the region’s unique challenges — balancing economic growth with environmental sustainability is no easy feat. But with collaboration and shared purpose, she believes progress is possible.

A Call to Future Changemakers

For those looking to follow in her footsteps, Claudia recommends building a strong foundation with a degree in environmental science. Environmental scientists interested in blending their skills with business management can opt for flexible programmes like MEMs

But more than qualifications, she believes what matters most is passion.

“Most of the people I’ve met in the environmental and social sector are very welcoming,” she says. “If you care deeply and want to make a difference, there’s always a place for you.”
