Reducing our energy footprint is a challenge, but one we are determined to meet. We are making progress, cutting our GHG emissions intensity by 27 per cent between 2008 and 2017.
As a whole, around three quarters of Rio Tinto’s total energy comes from hydro, nuclear and renewable power sources.
Aluminium smelting is an energy-intensive process, so using renewable energy sources has a significant impact on our carbon consumption. Around 80 per cent of the Aluminium group’s power needs comes from carbon-free sources, with 57 per cent generated by our own hydropower assets.
We have pioneered the development of efficient aluminium smelting technology that reduces electricity consumption and lowers emissions. Our proprietary AP TechnologyTM is recognised as a world-leader in clean aluminium production.
While these numbers are encouraging, there is more for us to do around managing energy use at our sites, which is our major source of carbon dioxide emissions.
