Upsun offers several regions for hosting project data. You can choose a region based on criteria such as its closeness to your users and its environmental impact.

​
Environmental impact

Whenever you create a project with us, we provide information about the carbon intensity level of the region you are choosing. This number indicates if the area is “greener”, meaning if the local electric grid relies on high-carbon energy sources or not. We consider a region as “greener” when the carbon intensity number is below 100 CO2e/kWh. When choosing a region with a lower carbon intensity number, you are choosing greener sources of energy behind the data center electricity consumption, like renewables or nuclear power. And we offer a 3% discount for this sustainable choice (estimate your discount). This carbon intensity data is sourced from the annual averages provided by the IEA and ElectricityMaps. If you want to see real-time emissions generated by each power grid, we recommend checking out ElectricityMaps live data. Summary of data being used in Upsun’s Region Picker when creating a new Project:
SourceLast update of this page
We usually consider a region “greener” when it has a carbon density <100 CO2e/kWh. Carbon intensity data sourced from IEA 2024, ElectricityMaps 2025. While ElectricityMaps give us more granularity for certain regions, we tend to favor IEA databases, as they are the most recognized on the market.8 April 2026
Information on carbon intensity is also available in the Upsun API. For example, to get a list of the regions and their carbon intensities, run the following command: 
upsun api:curl regions | jq -r '.regions[] | select(.available != false) | "\(.label): \(.environmental_impact.carbon_intensity)"'
See all available information in the API documentation.

​
Carbon Emissions dashboard

The carbon emissions dashboard provides an overview of the yearly carbon footprint associated with your cloud resource usage. Leveraging real usage data from the cloud bills provided by AWS, GCP and Azure, we partnered with the third-party climate experts Greenly to develop our own methodology to estimate your cloud emissions. Users can view total emissions and project specific emissions (in kg CO2e) for the past year.

​
Access the dashboard

This dashboard is accessible via the Emissions tab within the Billing section in Console.

​
How is this calculated?

We collect detailed billing data from our cloud service providers (including associated costs and quantities) and this information is represented as line items. Greenly, our climate expert partner for this project, calculates the energy use and embodied emissions for each line item. This is done through data gathering and modeling that estimates energy consumption, power usage effectiveness (PUE), and carbon intensity for the cloud providers. Using cost allocation models, your project’s share of emissions is then estimated. We have been working closely with Greenly to build upon the model, tailoring it to better reflect our specific data and technical requirements to ensure your emissions data is credible, compliant and supports your progress toward real, measurable sustainability targets.
Only AWS, GCP and Azure data are available in this dashboard. Other providers are not covered by this analysis.

​
What affects emissions?

  • Where you run: Data center regions vary greatly in grid-carbon intensity. Selecting a cleaner region is the most impactful way to reduce footprint.
  • What you provision: Emissions rise in proportion to the resources you allocate.
Optimizing code or app performance reduces emissions only if it leads to lower resource allocation.

​
Greener Region Discount

You can get a 3% discount on your resource usage if you host your project in one of Upsun’s eco-friendly regions:
  • Gravelines, France (fr-3.platform.sh)
  • Montreal, Canada (ca-1.platform.sh)
  • Moses Lake, United States (us-3.platform.sh)
  • Paris, France (fr-4.platform.sh)
  • Stockholm, Sweden (eu-5.platform.sh)
  • Zurich, Switzerland (ch-1.platform.sh)
The 3% discount covers application CPU, application memory, service CPU, service memory, and build resources. It doesn’t apply to the project fee or other billing aspects. It can be combined with other offers or discounts. See more information on the greener region discount.

​
Region availability

The regions listed here may be different from those available to you when you create a new project. Each organization can have its own rules for what regions to allow. When adding a new project, you only see regions allowed by your organization.

​
Region location

As an alternative, you can also browse the full region list at https://meta.upsun.com/regions.You can also use the following command with the Upsun CLI to find out where a given region is hosted:
upsun api:curl regions | jq '.regions[] | select(.available)  | .id + ": " + .provider.name + " - " + .zone + " - " + .timezone' | sort
The returned list contains, for each available region, its name, provider, geographic zone and its timezone - as shown above.

​
Public IP addresses

The public IP addresses for regions are stable, but not guaranteed to never change. Before any change, you are notified well in advance regarding affected projects. They’re useful for cases such as when you have a corporate firewall that blocks outgoing SSH connections. In such cases, add the inbound IP addresses for your region to your allow list.
