Troubleshooting
The following topics provide troubleshooting advice for errors and issues that you could encounter when using the AWS Sustainability service. If you find an issue that isn't listed here, you can use the feedback button on this page to report it.

Why do I get an Access Denied error when I access the console?
You need to set up IAM permissions to see data in the AWS Sustainability service. See Prerequisites to learn how.
Why are all the numbers zero in the AWS Sustainability console?
In order to see data in the AWS Sustainability console, you need to have usage of AWS services, otherwise your environmental impact will be zero. The console shows data at the 0.000001 metric tons of carbon dioxide equivalent (MTCO2e), or 1 gram, resolution. If you have AWS usage but the console shows zero, it means your impact is lower than 0.5 grams of CO2e.
Why can't I see data for 2021?
You can see your carbon data back to January 2022 or whenever your usage started, whichever happened later.
Why did my data change?
The calculation methodology is updated over time based on evolving data, climate science, and more. We will also update your data to fix any bugs we identify. All updates are documented in the Release notes page in the AWS Sustainability console.
What's the difference between LBM and MBM?
LBM and MBM are GHG Protocol methods used in Scope 2 and Scope 3 fuel- and energy- related activities (FERA) carbon emissions. Location-based emissions (LBM) reflect the average emissions intensity of the grid where energy consumption occurs. Market-based emissions (MBM) reflect supplier-specific emissions intensity after account for Energy Attribute Certificates (EACs), such as AWS' carbon-free energy purchases.
Why is carbon intensity different depending on the AWS Region?
Electricity grids in different parts of the world use various sources of power. Some use carbon-intense fuels (for example, coal), and some are primarily low-carbon hydro or other renewables. The locations of Amazon's carbon-free energy projects also play a role, because the energy produced by these projects is accounted against our emissions from Regions on the same grid. As a result, not all AWS Regions have the same carbon intensity.
Why can’t I see data from older methodology versions?
We publish data using the latest methodology version to ensure your estimated emissions are as accurate as possible. If you create a carbon emissions export on Data Exports, you will be able to preserve historical data calculated with all methodology versions from that point on. Data Exports publishes your data into an S3 bucket, with each methodology version having its own prefix. When a new version is released, historical data calculated using previous versions will remain in your bucket unless you delete it.
Note
We do not maintain previous methodology versions. To access your data from historical versions, you must create a Data Export before a new version is released. If this is important to you, create a data export now.
