How we help
Our culture would have us believe that sustainability is the responsibility of sustainability experts – we think that is nonsense.
We believe that people who care about the climate and nature crises – and social evils like poverty and inequality – are the greatest untapped resource that can help shift society to a world where people and nature flourish.
Stepping up to make a difference, even if it’s not in your job description, is sustainability leadership.

The Sustainability Leadership Knowledge Base
A collection of articles to support you to champion sustainability in your professional life.
We are part of nature
We are part of nature, but our culture leads us to think and behave in ways that deny this reality with disastrous results.
Sustainability leadership requires a deep emotional and psychological shift in how we understand and relate to rest of the living world.
Humans are naturally kind and caring
We live in a society that glorifies the worst of human nature, making us believe that people are inherently selfish.
This suppresses our natural instinct to look after each other. By recognising the reality that people are kind and caring we can break this vicious cycle.
We live in a world of abundance and potential
There is no fundamental shortage of the resources needed for good lives for all.
By tackling over-consumption by the few, and switching our focus to what really determines wellbeing, natural systems will recover, allowing us and the rest of the living world to flourish together.
