As an organisation that has declared Climate and Nature Emergency, we believe the most important thing for us to do is to win and facilitate decisive action to tackle dangerous climate change and restore nature, and for this to be achieved through a just transition.

However, it is also important that we 'walk our talk'. As an organisation, Sustain is deeply committed to ensuring that we adopt and promote responsible policies and practices on the issues we care about. Our staff are equally committed, and many are also leading lights on important issues and campaigns. So Sustain is also committed to listening, learning and developing our approach over time.

Making time for climate, nature and social justice (volunteering policy)
Sustain has adopted a system of ‘volunteering days’ for staff to take a day out of the office, to participate in some form of climate, nature or social justice activity. The purpose is to support Sustain staff taking part in climate, nature and social justice activities that develop knowledge, skills, sense of agency, diversity of experience and thoughtful connections.

Climate Change and Nature: Sustain has taken a keen interest in the rapidly accumulating evidence about the effect of food and farming on climate change and nature, as scientific evidence emerges that our food system is a very significant contributor to greenhouse gas emissions and biodiversity loss.
