MY VISION FOR SUSTAINABILITY AT NSG

Author: Dr Mélodie Herbas

Stepping into the role of Sustainability Lead at NSG feels both exciting and deeply personal. Sustainability has been part of my journey within the business for several years, from contributing to tender responses to supporting clients in meeting their own sustainability commitments.

Now, I have the opportunity to help embed sustainability more fully into how we operate, make decisions and deliver projects. For me, this role is about more than strategy or compliance. It is about shaping how we grow responsibly as a business while continuing to support the nuclear industry and the communities we serve.

SEEING SUSTAINABILITY AS A LONG-TERM RESPONSIBILITY

I view sustainability as fundamentally about long-term responsibility. It means safeguarding the future viability of our organisation while creating positive outcomes for people, the environment and society.
In a consultancy and project delivery environment, sustainability cannot exist in isolation. Every project involves technical, environmental and human considerations. Success lies in balancing cost, schedule, safety, technical excellence and environmental protection alongside meaningful social value.
It is about seeing the full picture. Every decision we make has consequences, some visible, others less obvious. Sustainable delivery means ensuring that our choices today do not create unintended impacts tomorrow.

My personal connection to sustainability began around a decade ago with a simple realisation about the amount of plastic waste generated through everyday grocery shopping. That moment prompted a broader reflection on responsibility and consequence, and those principles continue to guide my professional approach today.

BALANCING THE THREE PILLARS OF SUSTAINABILITY

Sustainability leadership requires balancing environmental, social and economic priorities. There is rarely a single perfect solution. Instead, progress comes from understanding different perspectives and aligning stakeholders toward shared objectives.

This involves listening carefully to colleagues, clients and partners and recognising the realities each group faces. Behavioural change plays an important role here. Sustainability is not about imposing rigid rules; it is about enabling informed decisions made with awareness, collaboration and empathy. When people understand why change matters, meaningful progress becomes possible.

BUILDING A VISION FOR MARKET-LEADING DELIVERY

Our ambition at NSG is clear: to become a market leader in sustainable delivery. Achieving this means moving sustainability from a parallel initiative into the foundation of every business decision.

My vision is to build a dynamic, purpose-driven sustainability function that works closely with project teams, leadership and clients. By strengthening our internal capability, we can transform our own operations while also helping our clients achieve their sustainability goals. In doing so, we create a ripple effect that extends across the wider sector.

Expectations from governments, regulators and clients are evolving rapidly. Remaining ahead requires proactive strategy, transparency and strong collaboration. Sustainability must be something we actively shape rather than something we react to.

LESSONS I’VE LEARNED

Before becoming Sustainability Lead, I spent significant time developing sustainability responses for competitive tenders. During that period, I saw a clear shift: sustainability questions became more technical, more demanding and increasingly decisive in contract awards. The message is clear — sustainability is no longer optional.

If we cannot demonstrate credible, measurable delivery, we risk missing opportunities. This is why innovation is essential. I encourage our teams to challenge established approaches, explore new ways of working and confidently present sustainable solutions to clients.
Progress depends on curiosity, creativity and the willingness to rethink how things have always been done.

MAKING SUSTAINABILITY EVERYONE’S RESPONSIBILITY

One of my central goals is to move sustainability beyond a specialist function and into everyday business culture.

Teams across NSG operate under different pressures and priorities, so building strong connections between departments is vital. Through open communication, shared learning and collaborative engagement, I want sustainability to feel accessible and relevant to everyone.

Ultimately, sustainability should not belong to one team or one role. It should define how we work — shaping decisions, strengthening relationships and reinforcing our identity as a responsible, forward-thinking organisation. By working together, we can turn sustainability from a commitment into a defining characteristic of NSG.
