The programme reinforced that sustainability is not a standalone discipline but a core component of business strategy, risk management and long-term value creation.
From the Classroom to the Boardroom: Why Global Perspectives Matter in Sustainability Leadership
Sustainability has become one of the defining business priorities of our time. Yet for many leaders, the challenge is no longer understanding why it matters. It is knowing how to translate sustainability ambitions into sound business decisions that create lasting value.
For Andrew Retschko, Senior Executive, Talent Engagement, Diversity & Inclusion, Sustainability & Community at Medibank, that challenge arrived as sustainability became an increasingly important part of his role. Looking for a broader perspective beyond Australia's rapidly evolving landscape, he chose the INSEAD Business Sustainability Programme to deepen his understanding of how organisations around the world are approaching the same questions.
A career shaped by purpose and continuous learning
Andrew's career has taken an unconventional path. He began as a secondary school Mathematics and Science teacher before making the transition into the corporate world.
Since joining Medibank, his responsibilities have steadily expanded across diversity and inclusion, community impact and sustainability.
"A highlight has been bringing these functions together to create stronger business and societal impact."
Today, he leads a diverse portfolio that includes sustainability strategy, governance and reporting, helping embed sustainability into decision-making while creating positive outcomes for people, communities and the environment.
Looking beyond the local perspective
As sustainability responsibilities became a larger part of his role, Andrew wanted more than technical knowledge of reporting requirements or regulations.
"I was looking for a programme that combined strategic business thinking with sustainability leadership."
INSEAD's international reputation, combined with its global cohort, stood out.
"The programme itself seemed really well rounded in taking a holistic view of how to build a clear business case for sustainability within an organisation, which applied perfectly to the changing conditions in my organisation and Australia."
His timing reflected broader changes taking place across Australia, where mandatory climate-related financial disclosures and new sustainability reporting standards are reshaping expectations for organisations.
While familiar with the Australian context, Andrew wanted exposure to international perspectives and best practices that could help him navigate an increasingly complex environment.
Seeing sustainability through a broader business lens
One of the programme's biggest takeaways was a shift in perspective.
"The programme reinforced that sustainability is not a standalone discipline but a core component of business strategy, risk management and long-term value creation."
Rather than viewing sustainability as a separate function, Andrew left with an even stronger conviction that it should be embedded throughout the organisation.
The programme's diverse case studies and global classroom played an important role in that learning.
"The global perspective. Learning alongside executives from different industries and countries challenged my assumptions and exposed me to approaches that would have been difficult to encounter through an Australian-only lens."
Learning from leaders around the world
For Andrew, the cohort was one of the programme's defining strengths.
"The diversity and quality of the cohort was exceptional."
Discussions brought together executives from organisations at different stages of their sustainability journeys, offering valuable comparisons and fresh perspectives that extended well beyond the classroom. He also appreciated the way the faculty balanced academic rigour with practical application.
"The professors were great in making sure the content focused on practical business insight, helping participants translate sustainability theory into real-world action."
At the same time, their depth of expertise encouraged thoughtful debate while creating an engaging learning environment.
Bringing learning back into everyday work
The value of executive education is often measured long after the programme ends.
For Andrew, the lessons continue to shape his work.
"The programme gave me a broader strategic framework for navigating sustainability challenges, particularly as Australian organisations adapt to evolving reporting requirements and stakeholder expectations."
More importantly, the learning has become part of his day-to-day decision-making.
"Since completing the course, I have found myself reflecting back on what I learnt at INSEAD to help solve the day-to-day challenges I have been facing, which has reinforced the value of the course for me."
Learning as a leadership responsibility
Having started his career as a teacher, Andrew views lifelong learning as an essential part of leadership.
"I believe learning is a responsibility of leadership. As an ex-teacher it's been ingrained in me that you can't sit still if you don't want the world to sail past you."
He believes this is particularly important in sustainability, where expectations, regulations and business realities continue to evolve.
"Especially in rapidly evolving fields such as sustainability, leaders need to continually challenge assumptions and seek new perspectives."
A global perspective for a changing world
Andrew would readily recommend the programme, particularly to Australian leaders navigating today's evolving sustainability landscape.
"For Australian leaders in particular, the programme offers valuable global context at a time when sustainability expectations, reporting obligations and stakeholder demands are evolving rapidly."
His experience reflects what many executives are discovering. As sustainability becomes increasingly integrated into business strategy, leaders need more than functional expertise. They need the ability to connect environmental and social priorities with business performance, organisational resilience and long-term value creation.
The INSEAD Business Sustainability Programme brings together experienced executives from around the world to explore these challenges through practical frameworks, real business cases and peer learning. For leaders seeking to strengthen both their strategic thinking and their ability to lead sustainable transformation, it offers an opportunity to gain perspectives that extend well beyond their own market.
