Google lessens data center emissions, yet carbon footprint is elevated due to persistent supply chain pollution.
Google, the tech giant, has announced significant strides in reducing carbon emissions from its data centers, achieving a 12% decrease in 2024 despite a 27% increase in electricity consumption. This improvement is attributed to increased energy efficiency through advanced cooling technologies, new AI chips, optimized software coding models, and the purchase of carbon-free energy (CFE) via large power purchase agreements, including geothermal, nuclear, solar, and wind power.
However, Google's overall carbon footprint increased in 2024, largely due to a sharp rise in emissions from its supply chain (Scope 3 emissions), which grew by more than 20%. Scope 3 emissions now represent about 73% of Google’s total carbon footprint, with approximately 60% of those emissions coming from electricity use within the supply chain.
Google's Chief Sustainability Officer, Kate Brandt, stated that the company has a better understanding of what it takes to get further down the path toward its climate goals. However, she acknowledged that navigating these external factors requires flexibility to maintain momentum towards Google's climate goals.
In response to these challenges, Google has set ambitious environmental goals: net zero emissions across its operations and value chain by 2030, a 24/7 Carbon-Free Energy goal to match electricity demand with carbon-free energy supply every hour of every day by 2030, globally, and the transitioning of suppliers to clean electricity to reduce Scope 3 emissions. Google plans to persist with these efforts, balancing cost, quality, and speed to continue reducing emissions and meeting its 2030 targets.
Google's efforts extend beyond renewables, as the company is pursuing technologies beyond renewables to address its clean energy needs, including enhanced geothermal, advanced nuclear, and biomass solutions.
In 2024 alone, Google signed agreements for over 8 GW of clean energy generation, the most in any year. Google has also made an investment in BlackRock portfolio company New Green Power (NGP) aimed at supporting the development of 1 GW of renewable energy projects in Taiwan.
Google's Energy Assessment Tool helps supplier facility managers identify energy efficiency opportunities across their operations. The tool, which has been used by over 1,000 suppliers, is part of Google's broader sustainability strategy to engage suppliers and reduce Scope 3 emissions.
Despite these initiatives, Google acknowledges that achieving these objectives has become more complex due to factors like slower-than-expected deployment of carbon-free energy technologies, rapid growth in energy demand driven by AI, policy uncertainties, and regions that are still early in their decarbonization journeys.
In summary, while Google has successfully cut emissions from its data centers and is aggressively pursuing carbon-free energy, the company's supply chain emissions are increasing and represent the major remaining hurdle. Google is actively working to reduce Scope 3 emissions through supplier engagement and clean energy transition as part of its broader sustainability strategy. The company continues investing billions in clean energy and infrastructure to support these goals.
