Microsoft is one of many large enterprises making public sustainability commitments, setting a bold target to become carbon negative by 2030. As part of this commitment, the company is evolving its supplier sustainability requirements, pushing for measurable emissions reductions across its entire supply chain. For suppliers, these changes present both challenges and opportunities.

The 2025 Disclosure Cycle introduces new requirements for emissions reporting, verification, and reductions, with fiscal year data submissions due by June 2025. This marks a pivotal shift toward greater transparency, accuracy, and accountability for all suppliers. Now is the time to establish the systems and processes needed to meet these standards and unlock new opportunities for collaboration.

At Greenplaces, we work with many companies reporting directly to Microsoft, giving us firsthand insight into the hurdles suppliers face and practical strategies to navigate them. For mid-market businesses, compliance isn’t just about meeting Microsoft’s standards—it’s an opportunity to demonstrate leadership, enhance operations, and build credibility in an era where sustainability is increasingly non-negotiable.

What’s new for 2025?

Microsoft’s updated supplier sustainability requirements emphasize  greater precision and transparency in carbon accounting. Here’s what you need to know:

• Independent Assurance Letter: Suppliers must provide an independent third-party Assurance Letter on total company emissions, covering Scope 1, Scope 2, and Scope 3 categories 1 through 8 (even if zero or immaterial). This letter can come from consultants who conducted or reviewed the work, or from auditors who validate the data.
• Service-level accounting (SLA) emissions: Suppliers are now required to provide emissions data tied specifically to their work with Microsoft. This includes breakdowns by service, using specific reference units and UNSPSC codes.
• Carbon-free electricity (CFE): Suppliers must demonstrate progress toward using carbon-free electricity for 100% of their operations related to Microsoft by 2030.
• Greenhouse gas (GHG) reduction plan: Suppliers must have a plan to achieve a 55% reduction in Microsoft service-level emissions by 2030, supported by actionable steps and data-driven benchmarks.

These changes reflect Microsoft’s commitment to raising the bar for sustainability within its supply chain, setting a standard other enterprises are likely to follow. Learn more about Microsoft’s supplier sustainability requirements on their website.

Steps to stay compliant

Meeting Microsoft’s sustainability standards might seem daunting, but breaking the process into manageable steps can help.

1. Understand your carbon footprint

Start by gaining a comprehensive view of your company’s Scope 1, Scope 2, and Scope 3 emissions:

• Scope 1: Direct emissions from owned or controlled assets, such as company vehicles or equipment.
• Scope 2: Indirect emissions from purchased energy, including electricity or heating.
• Scope 3 (categories 1-8): Upstream emissions, such as those from purchased goods, business travel, and employee commuting.

Greenplaces can help streamline this process by providing auditable, GHG Protocol-aligned carbon footprints.

2. Implement service-level emissions accounting

Service-level accounting isolates the emissions directly associated with your work for Microsoft. This ensures clarity and accuracy, enabling suppliers to meet Microsoft’s requirements with confidence. For example, emissions from business travel for Microsoft-related activities would be included, while travel for other clients would not.

Using detailed corporate activity data, Greenplaces can provide accurate Microsoft service-level emissions analysis to meet reporting standards.

3. Develop and execute a GHG reduction plan

Microsoft requires a 55% reduction in service-level emissions by 2030. Your reduction plan should include actionable strategies such as:

• Improving data quality for service-level emissions.
• Transitioning to renewable energy, such as purchasing Renewable Energy Credits (RECs) or installing on-site solar power.
• Optimizing operations by upgrading equipment, improving energy efficiency, or streamlining logistics.
• Encouraging sustainability initiatives among your vendors and within your supply chain.

4. Leverage Microsoft’s resources

Microsoft offers tools and training to help suppliers navigate these requirements. These resources can be invaluable in simplifying your path to compliance.

Why compliance matters

Non-compliance with Microsoft’s sustainability standards could jeopardize your contracts and harm business relationships. Beyond Microsoft, meeting these standards positions your business as a proactive, forward-thinking partner ready to tackle the next wave of climate regulations and market demands.
