The solutions already exist


Not long ago, it seemed impossible for women to get the right to vote or to abandon apartheid and slavery.

Our current challenges, such as climate change, the mountains of plastic entering our oceans each year, poverty and the scarily rising inequality, may seem impossible to overcome. But we can if we want to. At the heart of Big Tree Global lies a strong belief that we can evolve to a  flourishing world and that business has a vital role in getting there. 

The essential question is how can we best invest time, money and energy for the best outcomes? What are the right solutions that tackle the root cause of the issues? How can you integrate these as part of your business model? And how to balance this with a strong commercial platform?

Pioneers from across our planet have already developed innovative, effective solutions for each of our global issues. But to change the statistics we need these to become more mainstream.
We aim to inspire and support clients to develop powerful solutions as part of their business model that make a genuine, lasting difference and that are well balanced with strong commercial outcomes.
