 I'm Fiona Rideshead. I chair the Sustainable Health Coalition. I'm a senior associate of Cambridge Institute for Sustainability Leadership and I work mainly in the UK but also a lot with global organisations. As a senior associate at CSL I've really focused on bringing health into the sustainability agenda by thinking about how can we create conditions where people thrive but as we think across building sustainability in any sector how can you link the design of sustainable solutions that also promote people's health. The health care sector has a huge contribution to global warming. It's about 45% of emissions overall and there's a lot that we need to do around transforming clinical care, thinking about sustainable supply chains but also thinking about innovation and how in those solutions we can promote health as well as reducing environmental impact. CSL I think is a fantastic organisation to really promote system change because it brings innovation, thought leadership, educational programmes but it also has an amazing convening power to bring together people to come up with new solutions because the reality is we're all learning about how to make our society more sustainable and I think CSL is really well placed to do that. An example of sustainability in action that's kind of I think I've been impressed by in the last year is some work actually that I'm involved in where we're looking at how do you make innovation and health care more sustainable and we're bringing together industry from life sciences in particular with academics to think about how do we make research more sustainable and particularly about how do you measure it and I think what's really been impressive for me is the fact that people realise that they've got so much to learn from each other even though at the beginning of the work people thought well why are we going to work together so I think that's why convening power and getting people to work in partnership across systems is just so critical.
