It’s the world’s most consumed vegetable oil, used for everything from frying food to making it last longer – but can palm oil be produced in a way that doesn't wreak enormous environmental and human damage?
We visit the Sabah region of Malaysian Borneo, where different groups are working together to change the way palm oil is produced.
Presenter Graihagh Jackson hears about a certification system aimed at raising standards on smallholders, reducing the industry’s impact on biodiversity, and boosting incomes. And she speaks to an organisation fighting for the rights of indigenous communities against land-hungry palm oil companies.
Plus, what can consumers do to affect change in the industry? We hear how it's sometimes difficult to know whether products contain sustainable palm oil or not, and why the real impetus might need to come from China.
