Our plan—and, if I take a step back, Rio Tinto's plan as a group—is to lower its CO2 emissions by 50% by 2030 and to get close to zero by 2050, which is much more ambitious than the average in the mining industry.
The emissions of Rio Tinto aluminum are 70% of the total of the emissions of Rio Tinto. We want to reduce CO2 emissions, first, to meet our group's CO2 targets; second, to create a long-lasting competitive advantage; and third, I would say, to create a much more healthy aluminum business.
I've been in renewable energy before, as I told you, and it's clear now that when you look at the energy transition, in moving the world to renewable energy there are bottlenecks that need to be lifted, but that happens. What you need to attack is the how-to of each sector: steel, aluminum and transportation. Greening aluminum is part of that pool as well.
