What's the secret to effective engagement with those, particularly those top tier suppliers?

I think there's that ongoing drumbeat that you keep with the suppliers.

We engage at a lot of different levels.

We provide capacity building training.

We have teams in region who are real experts and able to talk to our suppliers one-to-one and do site visits.

And then having kind of like a multi-layer of programs that we work with suppliers on so that we've even got foundational compliance across all of our suppliers and then how we engage on a deeper level with those that are really making moves to decarbonize or improve other environmental impacts.

within their facilities and those real kind of like top movers who need a bit more in-depth help with their decarbonisation and technical advice and feasibility studies.

What's the secret to that as well? How do you make that work?
