The frenzied rollout of AI data centres in Australia is rushing through massive new projects, which will derail Australia’s energy transition unless the government urgently intervenes. View full report View this post on Instagram A post shared by Greenpeace Australia Pacific (@greenpeaceap) Key findings The frenzied rollout of AI data centres in Australia is rushing through massive new projects, which will derail Australia’s energy transition unless the government urgently intervenes. Our conservative assumptions mean this impact is understated, in this analysis. Australia’s biggest proposed data centre, the 1GW Mamre Road Data Centre Campus in Western Sydney, will generate peak annual grid emissions equivalent to that produced by 560,000 petrol cars for a year or all domestic flights within NSW in 2023. Data centres already fail to cover their own emissions with new renewables and their rollout will dramatically hold back Australia’s energy transition. No data centre operator analysed in this report adequately proves their claim of driving Australia’s renewable energy growth. Claims they are doing this through truly “additional” new power purchasing agreements for renewable energy are unsubstantiated.  There are early signs of a data centre-fuelled gas boom in Australia, which will come with massive, nationally significant climate costs. For example, the Tamboran proposal for the Northern Territory would effectively double the state’s emissions. In NSW, Cloud Carrier’s proposed gas-fired project would wipe out NSW’s entire projected 2028 emissions cuts.

New analysis shows that on-site gas for data centres globally could fuel emissions that exceed Brazil’s total power grid emissions by 2030. Fossil fuel corporations are quietly joining the data centre lobby group as members, and sponsoring and attending technology industry conferences. The two industries are reinforcing each other’s talking points and PR spin.

Data centres can be ‘right sized’ through community ownership schemes, well-deployed AI software and strict moratoria to allow for democratic governance of this industry.
