Irwin's introduction

I have consistently gravitated towards opportunities that enable me to explore, learn, and contribute to a greater purpose within an organisation. As an advisor, I focus on developing sustainability strategies and managing sustainability transformation for large organisations. I specialise in sustainability advisory (both strategy and reporting), impact investing, stakeholder engagement, and climate action, and my expertise and passion align with driving positive change. I have actively advocated and participated in foundations, as well as not-for-profit partnerships, in the Asia Pacific region. Currently, I am in the media space leading Dentsu’s global ambition to be a recognisable, purpose-driven company. In this role, I am dedicated to supporting brands in achieving their sustainability goals through innovative strategies and initiatives.

Expertise in the following
What brought you to sustainability?

My connection to sustainability comes from a blend of curiosity and the drive to make an impact using technical knowledge. I am a chemical & environmental engineer by qualification, and I love the idea of ties between science, technology, and creativity to solve technical issues. Plus, the idea of contributing to a healthier society and planet is both inspiring and urgent.

Which sustainable actions are you in charge of or have you implemented in your organisation?

I have worked on both forward-thinking strategies and reporting disclosures in many organisations. My consultancy background has allowed me to explore every aspect of sustainability in business.

Which challenges did you meet and how did you overcome them?

Shifting mindsets — be it among individuals, companies, or policymakers — can be tough. People often hesitate to adopt new approaches due to uncertainty or perceived costs.

I focus on storytelling and data to bridge this gap, showing the tangible benefits of sustainability practices through real-world examples and measurable impacts.

What are you most proud of?

One of the things I’m most proud of in my sustainability work is helping to bridge the gap between vision and action. It’s incredibly fulfilling to see ideas and strategies — whether it's a circular economy initiative, a renewable energy transition, or a community-driven conservation project — move from concepts to tangible results that make a difference.
