About CSL

We believe that people hold the potential to facilitate the transition to sustainable ways of living and a global society, and we help them to be as effective as possible in doing this.

What We Do


We believe that people hold the potential to facilitate the transition to sustainable ways of living and a global society founded on a shared ethical framework.

Taking our cue from the Earth Charter Initiative, our broad vision for a positive future (framework) includes but is not limited to: respect and care for the community of life, ecological integrity,  universal human rights, respect for diversity, economic justice, democracy, and a culture of peace.

We believe our world needs leaders and change makers who have the commitment, courage and skills to drive positive, transformative change. We enable leaders (individuals and organisations) and equip them with the skills and insights they need to create the future they want – the future we all need.


We amplify the creativity, capability and community of emerging leaders by deepening their understanding of how they can influence change, challenging their thinking, building their confidence and effectiveness, and connecting them to a community of practice of other leaders to learn from and be supported by.

We are a not for profit organisation. We believe in the power of cross-sector collaboration so we work with individuals, communities, corporations and government. We know that leaders for the future will come from all industries and disciplines, so we actively look for partners and participants from across the spectrum, creating sustainability leaders working for a better future in all areas of business and civic life.


We run a series of award-winning training programs, designed to give passionate individuals the agency and ability to create the change they envisage.

Our programs are innovative, immersive, and transformative. They use cutting edge pedagogy and curriculum, all based on a robust best practice and academic framework.

All of our programs cover a mix of the following areas which we believe are key capabilities for leaders of the future:

  • Philosophy of leadership
  • Leadership for sustainability
  • Self enquiry and personal effectiveness
  • Values and ethics
  • Systems thinking
  • Creative and innovative thinking
  • Dynamics of change
  • Making things happen
  • Collaboration
  • Influencing and enabling others
  • Resilience
  • Communications and advocacy

We’ve been doing this since 2004, and we are consistently amazed by the results.

We know it works, because our program participants go on to do great work in their personal and professional lives. So far, we’ve helped more than 350 individuals working to create positive change.


We believe passionately in our human potential to live with compassion and connection.


We believe in challenging people to think and feel differently, and to live a life of meaning and purpose.


We believe that truly understanding ourselves, others and the environment around us is a key step towards sustainability – both of ourselves as individuals, and of the world we live in.


We believe in fostering the kind of leadership needed to tackle the complex challenges we face in sustaining the life of all species.


We believe in leadership that is creative, compassionate and courageous. Leadership that comes from the heart and the head, that is insightful, purposeful and playful. Leadership that enables and empowers other leaders to take up the challenge.


We believe that the power of enabling a community of people working for positive environmental and social outcomes cannot be underestimated.
