Google recently released its annual sustainability report, and the results are not encouraging. The report revealed that the company’s greenhouse gas emissions have risen by almost 50 percent over the past five years. This increase is primarily attributed to the significant energy consumption of artificial intelligence (AI) technologies. It appears that Google has a long way to go before it can achieve its goal of net zero emissions by 2030.
One of the most concerning statistics in Google’s 2024 Environmental Report is the staggering 48 percent increase in greenhouse gas emissions compared to the base year of 2019. This amounts to a year-on-year increase of 13 percent, resulting in 14.3 million tonnes of carbon dioxide equivalent. To put things into perspective, this is equivalent to the emissions of over 3.1 million cars in a year. Google attributes this spike in emissions to the growing energy consumption of data centers and the emissions generated by its supply chain. It is no surprise that AI plays a significant role in this, as even a single AI search summary consumes 10 times more energy than a standard Google search.
Google has been rapidly integrating AI into various aspects of its business operations, ranging from its Translate tool to its Photos app. This widespread adoption of AI technologies poses a challenge in reducing emissions, as the increased intensity of AI compute inevitably leads to greater energy demands and associated emissions from technical infrastructure investments. Despite acknowledging the potential difficulties in reducing emissions, Google shows no intention of slowing down on its AI integration.
The company’s annual report suggests that there may be a temporary rise in greenhouse gas emissions before a decline. Unfortunately, Google does not offer a concrete plan on how it intends to achieve this. It also acknowledges that some barriers preventing it from reaching its net zero target do not currently have solutions. This lack of clarity raises questions about the feasibility of Google’s net zero goal.
Google’s approach to reducing emissions seems to rely heavily on the broader clean energy transition and the uncertain future impact of AI on the environment. The company’s report states that navigating through these uncertainties will necessitate an evolving approach. Additionally, Google cites a report by the Boston Consulting Group, which claims that AI has the potential to reduce global greenhouse gas emissions by five to 10 percent. While this sounds promising, the report pays little attention to the emissions cost of AI technologies themselves. Furthermore, the report was conducted by members of BCG GAMMA, a division of BCG that sells AI solutions to companies, which raises potential conflicts of interest.
Amidst the concerning emissions data, Google does highlight some positive sustainability efforts in its report. The company states that it has replenished approximately 18 percent of the freshwater used by its data centers and offices, tripling the percentage from the previous year. Although it falls short of Google’s 120 percent goal, this progress is still significant. Additionally, the packaging for new products launched in 2023 was 99 percent plastic-free, showing a commendable improvement.
However, the report also reveals areas where Google has fallen short. The diversion of food waste from landfill decreased from 85 to 82 percent, indicating a regression in this aspect of sustainability. Furthermore, the amount of recycled plastic used in Google products decreased from 41 to 34 percent, indicating a decline in the company’s efforts to incorporate recycled materials.
In conclusion, Google’s sustainability report highlights both progress and setbacks in the company’s efforts to reduce greenhouse gas emissions and improve overall sustainability. The significant increase in emissions, particularly driven by the energy consumption of AI technologies, poses a significant challenge. While Google acknowledges the difficulties ahead, it lacks a clear plan to achieve its net zero emissions goal by 2030. As the company continues to integrate AI into its operations, it must also prioritize finding sustainable solutions that minimize the emissions associated with these technologies.
