Microsoft's questionable plan to counteract AI's carbon footprint suggests underground disposal of waste – a move that strongly hints at greenwashing efforts
In the rapidly evolving world of technology, Microsoft's focus on generative AI and cloud infrastructure expansion is causing a significant strain on data center infrastructure globally. This shift has led to a surge in energy consumption and carbon emissions, sparking concerns about the company's sustainability efforts.
Last year, Microsoft's energy use increased by a staggering 168%, highlighting the enormous environmental cost of scaling AI compute resources. This increase is reflected in the company's annual sustainability report, which revealed a 23.4% increase in total carbon emissions compared to its 2020 baseline.
Criticisms and concerns regarding Microsoft's sustainability efforts primarily focus on rising carbon emissions, questionable waste management approaches, and accusations of greenwashing.
To offset emissions, Microsoft signed a deal with Vaulted Deep to bury organic waste such as manure and sewage deep underground, claiming it permanently removes carbon. However, critics argue this method "stinks of greenwashing," as it is seen as an unsophisticated fix that obscures the real environmental toll of AI infrastructure expansion rather than substantially reducing emissions.
Microsoft's disclosures do not fully include "enabled emissions" — carbon released from downstream AI applications like oil exploration or logistics optimization. These are part of Scope 3 but remain absent from reporting, which some experts see as a significant omission undermining transparency about AI’s full environmental footprint.
Despite these criticisms, Microsoft is not resting on its laurels. The tech giant is implementing novel data center cooling techniques and using cross-laminated timber (CLT) in data center construction to reduce carbon emissions. Microsoft is also investing in carbon removal projects, such as a deal with Chestnut Carbon for reforestation in the United States to offset 7 million metric tonnes of carbon. In April, Microsoft signed a deal with carbon capture company AtmosClear to remove nearly 7 million tonnes of carbon emissions.
However, these efforts do not significantly offset Microsoft's yearly emissions of around 15 million tonnes in FY24. The company is considering various methods to meet surging energy demands, including reopening nuclear power stations, geothermal energy projects, and development of small modular reactors (SMRs).
The growing energy demands and emissions raise serious concerns about the effectiveness and sincerity of Microsoft's sustainability efforts. Critics emphasize that reductions reported using market-based accounting methods are misleading and that the company's "carbon negative by 2030" target has taken hits due to these emission increases.
As Microsoft and its counterparts in the industry rush to find a quick fix for sustainability issues due to their focus on generative AI, it is crucial that they consider the long-term impact of their actions and make substantial changes to address the escalating environmental impact.
