How to network and why it matters in sustainability

In sustainability and environmental practice, connection is not simply helpful, it is essential. The challenges we face are complex, interconnected, and constantly evolving.

No single professional, organisation, or sector has all the answers. That is why cultivating and maintaining a strong professional network is vital. 

Whether you’re in the early stages of your career or have decades of experience, relationships are at the heart of effective sustainability practice. Our work depends on shared insight, diverse perspectives, technical expertise and mutual support, all of which are built through connection. 

A personal perspective 

I have not always found networking easy. Early in my career, I often felt uncomfortable initiating conversations at events. One approach I found helpful was positioning myself near the coffee bar and simply greeting people with a friendly, “I don’t think we’ve met before,” as they turned around with their drink. It was a small step, but it often led to engaging and insightful conversations. 

Over time, I came to understand that meaningful networking is not about perfect introductions or forced conversations. It is about openness, being prepared to listen, learn and connect. 

Now, with many years in the profession, I can say with confidence that some of the most valuable insights I have gained, and some of the most enduring relationships I have formed, came from those unplanned, informal conversations. They have shaped my thinking, broadened my perspective and, in many cases, had a lasting influence on my career and approach to leadership. 

Why networking matters 

Sustainability professionals frequently work within complex systems, addressing environmental, social, and economic issues simultaneously. A strong professional network helps to: 

• Stay informed about changing regulations, best practice, and emerging trends 
• Understand how other sectors and disciplines are approaching shared challenges 
• Exchange ideas, share lessons learned, and build mutual support 
• Identify opportunities for collaboration, innovation, or development 
• Reduce the sense of isolation that can arise in small teams or independent roles 

The people you meet through networking often become mentors, collaborators and advocates and, in some cases, long-standing friends. 

Practical ways to network effectively 

The concept of networking can sometimes feel daunting, but it is fundamentally about building authentic professional relationships. Here are a few approaches that can make a real difference: 

• Show curiosity. Ask thoughtful questions and be genuinely interested in others’ work 
• Follow up. Reconnect with former colleagues or reach out after an event or webinar 
• Participate. Join professional forums, attend ISEP events and contribute to community discussions 
• Share your experience. Your insights may provide clarity or encouragement to others 
• Offer support. Recommend resources, make introductions or simply listen. 

Over time, these actions help to establish trust, credibility and visibility within the profession. 

Conversation starters  

A great way to start a conversation when networking is to look for someone standing on their own, as they are often the most open to being approached. Walk over with a warm smile, open body language and confident eye contact, then say, “Hi, I don’t think we’ve met before. I’m [Your Name].” This simple, friendly opener sets a positive tone. Follow up with an open question like “How are you finding the event so far?” to keep the conversation flowing. Be genuinely curious, listen actively and share a little about yourself when it feels natural. The key is to be warm, open and approachable, remembering that everyone is there to connect. 

The importance of engaging with early-career professionals 

Those of us with more experience in the field have a responsibility to create space for those who are just beginning. Engaging with early-career professionals brings value not just to individuals, but to the sustainability profession as a whole. 

Newcomers bring energy, creativity and a fresh perspective. They often see things differently and are not afraid to ask important questions. In return, we can offer context, share practical knowledge, and help them navigate the challenges of the profession. 

By fostering inclusive, accessible networks, we support a stronger and more resilient community of practice – one that better reflects the values we advocate in our work. 

Final thoughts 

Networking is not a separate task or an occasional activity. It should be embedded in how we grow, lead and learn as professionals. As ISEP enters a new phase, we have an opportunity to deepen our connections and continue learning across disciplines, generations and sectors. 

Strong networks make us more informed, more capable, and ultimately more effective in driving lasting change. The conversations we start today could shape the solutions we create tomorrow.
