What we have to do as a society is to find ways to extract minerals with a zero-carbon footprint going forward. There's not a lot of point in creating a lot of emissions, a lot of CO2, to save something elsewhere. We have to do both together. The commitment that we've taken as a company at Rio Tinto is to stay in line with our commitment to reduce our emissions by 2030 in line with the Paris Agreement, and also to be net zero in 2050.
That is going to require an awful lot of innovation. We will need to partner with people outside of our company because we don't have the ability to do all that.
