Microsoft Counts 80 Million Tonnes of CDR and Four Hard Lessons

Microsoft has signed offtake agreements for 80 million tonnes of additional carbon dioxide removal since mid-2023, with deliveries running to summer 2026. The figure anchors a new paper in which the company distils six years of CDR procurement into four lessons for buyers, developers, financiers and policymakers in emerging compliance markets.

The program launched in 2020 and has backed numerous removal projects to date. Since publishing its previous reflections on carbon removal purchasing in 2023, Microsoft has continued to refine its quality criteria annually and has sponsored technical whitepapers intended to make complex qualitative issues practically accessible.

The paper divides the decade neatly. The first five years, Microsoft writes, were about building knowledge and gaining practical experience. The second half should be about translating those insights into action: learning through deployment while accelerating responsible scale.

What are the four lessons?

The first is patience. In Microsoft's experience, a CDR project takes between 5 and 8 years from inception to the receipt of first credits. The company's verdict is blunt: any business working toward removal targets for 2035 or beyond should start procuring opportunities today.

The second is risk. Project execution, Microsoft notes, carries setbacks clustered around five areas: permissions, market risk, financing, execution, and generation. Buyers who model only the happy path will find the actual path expensive.

The third concerns the tension between speed and scarcity. Methodologies for quality remain thin, yet near-term deployment cannot wait for perfect ones. Scaling carbon removal, in Microsoft's view, demands progress on two fronts at once: deploying projects responsibly today, and continuously strengthening quality standards as experience, science and the market evolve.

The fourth is structural. Public-private alignment, the paper argues, can unlock accelerated CDR advancement. Projects advance more effectively when private-sector demand is reinforced by public investment, risk-sharing mechanisms and clear policy frameworks.

Why does a buyer's paper matter to the market?

Microsoft is one of the most prominent buyers of CO2 removals, and its procurement behavior functions as a de facto benchmark for the voluntary market. When it publishes criteria, developers align to them. When it flags a 5-to-8-year delivery lag, financiers price it.

The paper's stated audience extends beyond voluntary buyers. Microsoft addresses policymakers in emerging compliance markets directly, positioning its lessons as input for regulators designing removal obligations rather than as private commentary.

The timing is deliberate. The company frames 2025 as the hinge between a learning phase and a deployment phase, with its own 80-million-tonne offtake book as evidence that demand at scale already exists.

What happens next?

The milestone to watch is delivery. The offtake agreements run to summer 2026, and the paper's own risk taxonomy — permissions, financing, generation — describes exactly where those tonnes can fail to materialize.

Quality criteria will keep moving too. Microsoft has updated its standards every year and has begun addressing delivery risk explicitly in joint criteria work with Relae. Expect the 2026 reflections to measure the program less by signatures and more by credits actually issued.

The lesson count, for now, stays at four.
