Microsoft Partners with Chestnut Carbon in Landmark 7MT Carbon Credits Deal

A Major Step in Microsoft's Sustainability Efforts

Microsoft has once again taken a bold step in its carbon removal strategy, entering a long-term agreement with Chestnut Carbon, a U.S.-based leader in nature-based carbon removal.This deal will provide Microsoft with over 7 million metric tons of carbon credits, sourced from Chestnut’s expansive Afforestation, Reforestation, and Revegetation (ARR) project across the Southern United States.

The partnership builds on an initial agreement from December 2023, expanding Microsoft's commitment to leveraging sustainable carbon sequestration solutions. Through this initiative, 60,000 acres of land will be restored with 35 million native trees planted, reinforcing the company’s goal to become carbon-negative by 2030.

Chestnut Carbon’s Sustainable Restoration Project

Chestnut Carbon is leading one of the most scalable nature-based carbon removal initiatives. Their Sustainable Restoration Project focuses on transforming degraded croplands and pastures into thriving forests.

By working closely with local foresters, landowners, and nurseries, Chestnut ensures that reforestation efforts align with regional soil, drainage, and land-use characteristics.

Key Aspects of the Project

• Designing planting sites based on ecological data
  
• Monitoring tree survival rates for long-term impact
  
• Measuring carbon sequestration with proprietary technology, verified by Gold Standard
  

Ben Dell, CEO of Chestnut Carbon and Managing Partner of Kimmeridge, highlighted the importance of this agreement, stating, "We’re excited to be expanding our collaboration with Microsoft given their market leadership in net-zero commitments. The signing of a second agreement within a year reaffirms their confidence in our ability to deliver high-quality removal credits."

Delivering High-Quality Carbon Credits

Unlike traditional emissions-avoidance initiatives, Chestnut's project focuses on removal-based carbon credits, ensuring long-term environmental benefits. By adhering to Gold Standard verification, the company maintains strict quality control over its sequestration methods.

Why This Project Stands Out

• Durability: Long-term conservation efforts protect against fire, disease, and climate threats.
  
• Additionality: The initiative restores degraded land that would otherwise remain barren.
  
• Environmental Impact: Enhanced air and water quality, improved wildlife habitats, and strengthened local economies.
  

Microsoft’s Expanding ARR Portfolio

Through this partnership, Microsoft will support Chestnut Carbon in expanding its ARR portfolio to 500,000 acres by 2030, with an ambitious target of removing 100 million metric tons of CO2 over the next 50 years. This collaboration is a significant part of Microsoft's broader climate strategy, which includes investments in bioenergy with carbon capture and storage (BECCS), direct air capture (DAC), and enhanced rock weathering.

Brian Marrs, Senior Director of Energy & Carbon Removal at Microsoft, emphasized the deal’s impact, stating, "This agreement with Chestnut Carbon is another positive step towards Microsoft’s goal to become carbon-negative by 2030. We look forward to scaling forest restoration within the United States and attracting sophisticated private capital in the process."

Microsoft’s Carbon Removal Strategy

In its latest sustainability report, Microsoft revealed that it contracted over 5 million metric tons of carbon removal credits in 2023, with commitments spanning the next 15 years. The company strategically invests in projects with varying durability levels, balancing short-term and long-term climate solutions.

Key Elements of Microsoft’s Portfolio

• Low-Durability Solutions: Forestry and soil-based methods store carbon for up to 100 years.
  
• Medium-Durability Solutions: Biochar sequesters carbon for up to 1,000 years.
  
• High-Durability Solutions: BECCS and DAC provide over 1,000 years of carbon storage.
  

Commitment to a Carbon-Negative Future

Microsoft's carbon removal efforts extend beyond forestry projects. Nearly 80% of its 2024 carbon credits come from BECCS projects, with its largest purchase of 3.3 million credits from Stockholm Exergi in Sweden. Despite these efforts, the company saw emissions rise by 29.1% in 2023, underlining the urgency of securing high-quality carbon credits.

This new partnership with Chestnut Carbon represents a significant milestone in Microsoft's sustainability journey. As the company continues to scale its climate investments, projects like these will play a vital role in achieving its ambitious carbon-negative goal by 2030 and offsetting historical emissions by 2050.
