Carbon emissions data at your fingertips

Tracking environmental impact can be fragmented, time-consuming, and disconnected from operational data. Beyond simply checking ESG reporting boxes or making sure your company is CSRD compliant, actively monitoring environmental impact is the foundation for building an effective sustainability strategy. 

At Upsun, we know that measuring progress is the first step toward improvement. Starting in 2024, we’ve made your annual carbon emissions data easily accessible in the Billing section of the Console -and the 2025 figures are now available.

Now you can easily track last year’s environmental impact at both the Organization and Project levels, and proactively incorporate this data into your financial and environmental strategies.

Organizations across industries can use this emissions data to:

• Meet ESG reporting requirements and CSRD compliance standards
• Build data-driven sustainability strategies
• Track progress on environmental goals
• Make informed decisions about resource allocation

Organization owners and users with billing permissions can access this data immediately—no setup required

How we calculate your emissions

We've simplified this process by partnering with Greenly to deliver precise emissions calculations using detailed billing data from our cloud providers. All calculations follow GHG Protocol standards to ensure your data meets compliance requirements.

Going forward, emissions data for the previous year will be automatically available in the Console and via our API, which means you get consistent, reliable data without manual collection or complex integrations.

More accurate data with updated methodology

If you received your 2024 emissions data last year, the 2025 emissions might be significantly different. If you have not done any major hosting changes, the gap between the 2 years might reflect improved calculation accuracy on our side, not actual emission reductions.

What’s changed from 2024?

In 2025, the methodology used to calculate project carbon dioxide emissions is still aligned with the GHG Protocol but has been updated based on 3 primary factors:

1. Updated electricity emission factors: Every year, we update emissions factors to reflect any significant changes in energy sources used at region level, reflecting for instance the decarbonization efforts at country level. As usual, we updated the emissions factors and in 2025 chose to blend IEA data (the most recognized actor) with ElectricityMaps (for some regions, like the U.S).
2. Granular PUE integration: Where publicly disclosed by providers, we have factored in regional PUE (Power Usage Effectiveness) data to calculate electricity consumption with higher precision.
3. Extrapolation Variability: For cloud services lacking specific infrastructure data for some services, we employ extrapolation. This process can result in year-over-year reporting variability.

What's next

Carbon accounting is an ever-evolving process. We are continually refining these calculations as emissions accounting standards and cloud provider strategies evolve.
