Global AI race heats up, but its environmental toll is raising alarms . Tech giants Google and Amazon report sharp carbon emission spikes,casting doubts on their carbon neutrality promises.
Google's emissions jumped 82% by 2025 from 2019. Just last year, up over 18%. Still,they vow to cut emissions in half by 2030. Meanwhile,Amazon's data shows 58% rise in emissions over same period,with a 16% increase last year. They target carbon neutrality by 2040.
Both firms now emit more carbon per revenue dollar than before. Their emissions are outpacing sales growth. Kate Brandt,Google's Chief Sustainability Officer, admitted AI expansion is outstripping grid decarbonization. Cara Hurst from Amazon echoed that AI demand might derail their green goals.
Google pumped out 18.8 million tons of greenhouse gases last year, mainly from data centers and chip production. Amazon hit 80.85 million tons,fueled by cloud computing and global logistics. AI's energy appetite is massive—11th largest consumer globally now, could be sixth by 2030.
Chitka Wijensamy from UC Berkeley points out profit often trumps sustainability for companies . Cutting costs means green investments may lag. Supply chain control,especially in energy and minerals,is a major hurdle.
UN reports show data centers use more energy than all but ten countries . At London Climate Week, António Guterres,UN Secretary-General, urged AI firms to be transparent about their impact. He called for every data center to adopt renewables by 2030.
Despite concerns,Meta and Microsoft have yet to release similar reports . AI boom,since ChatGPT's launch in late 2022,drives data center expansion,demanding electricity,water for cooling, and materials like concrete and steel.
In three years, Google's electricity use doubled—like Greece's total consumption. Amazon's data center construction emissions soared over 40% in a year. Both firms are pushing renewables,Google signing transparent fuel contracts,investing in nuclear and geothermal . Amazon claims top spot in renewable energy buying,investing in small nuclear reactors and electric trucks.
AI's rise makes its environmental cost hard to ignore. Can tech leaders balance innovation with sustainability…?
