Google's Carbon Emissions Soar 51% as Artificial Intelligence Hampers Green Efforts

Google's carbon emissions have skyrocketed by 51% since 2019, largely due to the surge in artificial intelligence models requiring significant datacentre capacity. The tech giant's efforts to go green have been hindered by its growth in datacentre electricity consumption, which has increased by 27% year-on-year. This is primarily driven by the need to power AI models such as Gemini and OpenAI's GPT-4, which relies heavily on datacentres.

Key Takeaways:

• Google's carbon emissions have increased by 51% since 2019, largely due to the growth in datacentre capacity required to power AI models.
• Datacentres play a crucial role in training and operating AI models, with electricity consumption expected to double to 1,000TWh (terawatt hours) by 2026, equivalent to Japan's electricity demand.
• The International Energy Agency estimates that datacentres will use 4.5% of global energy generation by 2030.
• Google has invested in renewable energy and carbon removal technology, but has failed to curb its scope 3 emissions, which are those further down the supply chain.
• The company highlighted the slower-than-needed deployment of carbon-free energy technologies, such as Small Modular Reactors (SMRs), which are behind schedule due to regulatory issues.
• Google's total ambition-based emissions were 11.5m tons of CO2-equivalent gases, representing an 11% year-over-year increase and a 51% increase compared with the 2019 base year.
• The company aims to help individuals, cities, and partners reduce 1GT (gigaton) of carbon-equivalent emissions annually by 2030 using AI products.
• Google has eliminated plastic packaging for new Google products launched and manufactured in 2024, meeting its environmental goal early.

Statistics:

• Google's datacentre electricity consumption has increased by 27% year-on-year.
• The International Energy Agency estimates that datacentres will use 4.5% of global energy generation by 2030.
• The total electricity consumption of datacentres is expected to double to 1,000TWh (terawatt hours) by 2026.
• Google has signed over 170 agreements to purchase 22 gigawatts of clean energy since 2010, including 25 new clean energy deals added online in 2024.
• The company has signed contracts for 8 gigawatts of clean energy in 2024, a record year for clean energy deals.
