A surge in carbon removal credit purchases from major tech firms like Microsoft and Google is creating a global supply crunch—an inflection point poised to accelerate the next phase of climate action and reshape the rules of corporate sustainability.
How Big Tech Sparked a Carbon Credit Supply Crunch
Microsoft, Google, and other tech giants are buying up carbon removal credits at unprecedented speed, driving prices for high-quality credits to nearly four times the rate of cheaper alternatives such as credits tied to forest-preservation projects. Since 2019, these companies have collectively invested hundreds of millions of dollars into durable carbon removal, sharply accelerating over the last two years as demand soared to offset emissions from rapidly expanding AI-powered operations.
Durable carbon removal credits, which include projects like biochar production and direct air capture, are distinguished by their long-term storage of carbon dioxide—qualities highly prized as the world races to meet ambitious climate goals. Market tracker CDR.fyi estimated a combined $10 billion in spot-market purchases and long-term offtake agreements, signifying a seismic shift in how corporations, especially in tech, approach climate responsibility.
The Urgent Context: Tech Expansion, AI, and Emissions
As AI becomes integral to their operations, tech companies’ rapidly expanding data center footprints are driving up both profits and emissions. The resulting surge in demand for durable carbon credits is a direct ripple effect of AI’s transformative impact on the economy and energy use—a trend noted by industry leaders and market analysts. With profits up, major players are funnelling returns into climate offsets, viewing carbon removal credits as core to their future business models.
- Microsoft, for example, has anchored large-scale, multi-year procurement deals to stimulate market innovation and supply growth.
- Google and others are increasingly cited as the primary force behind skyrocketing volume and price for biochar and direct-air-capture credits.
Why Carbon Removal, Not Just Offsetting, Matters
Scientists and climate experts stress that simply reducing emissions is not sufficient—active removal of atmospheric carbon is essential for net-zero pathways and a realistic shot at slowing global warming. Historically, voluntary offset projects were criticized for unverifiable claims; the current demand spike reflects a new era of rigorous, durable removal practices.
The highest-value credits now stem from:
- Biochar projects: Converting waste biomass into stable carbon stored in soils.
- Direct air capture: Physically removing CO2 from the atmosphere for long-term storage.
- Land restoration: Revitalizing degraded ecosystems with long-term sequestration value.
Market Consequences: Supply Can’t Keep Pace With Demand
This gold rush for durable carbon credits is rapidly creating a supply shortage. According to climate platform Patch, one-third of customer requests focus on biochar credits—yet only a fraction can be fulfilled due to such limited availability. In 2024, just 8 million tons of durable carbon removal were purchased; projections for this year already hit 25 million, a pace outstripping actual issued supply—less than 1 million tons to date, driven mostly by biochar.
Lukas May, chief commercial officer at carbon registry Isometric, notes the “desire for high quality is very real” and increasingly dominated by the purchasing power of Big Tech. These companies’ moves have effectively established a new price floor for the industry, outcompeting other sectors vying for the same limited supply.
Innovative Solutions: Building Your Own Credits
The squeeze is prompting new strategies, with some companies moving to generate credits themselves. Pure Data Centres Group, a supplier to tech firms, is investing £24 million (about $31.6 million) to launch the United Kingdom’s largest biochar facility. Their chief executive, Dawn Childs, notes that sourcing reliable, high-quality credits is nearly impossible in the open market. The project is designed to deliver 9,000 tons of carbon removal annually once scaled—a direct response to industry bottlenecks. Plans are already in place for more sites to meet persistent demand.
Turning Crisis Into Opportunity: The Long-Term Impact
What looks like a market failure—Big Tech outbidding everyone else and creating a supply crunch—may actually be a crucial lever for global climate progress. The scramble for credits forces innovation and multiplies incentives for new carbon removal projects worldwide. Firms with the most to gain from operational growth are now in the driver’s seat to build, finance, and mainstream technologies that could have wide-reaching impacts far beyond their own emissions.
As this supply-demand dynamic matures, experts predict:
- Further price increases for truly durable credits, pushing even more innovation in removal methods.
- Increased investment in verification, transparency, and international market standards.
- A gradual expansion in high-quality supply, eventually making credits more accessible to other sectors and smaller players.
This moment sets the stage for the next phase of climate action, where technology, market forces, and environmental urgency converge to accelerate solutions at scale.
