I would like to have a carbon footprint tool to move us to be carbon neutral.

Amazon has a carbon footprint tool (https://aws.amazon.com/blogs/aws/new-customer-carbon-footprint-tool/).

It would be great to have the same overview on apps and addons on heroku.

Also I think heroku us is on us-east-1 which is not the carbon neutral(https://www.greenpeace.org/usa/reports/click-clean-virginia/).
How does heroku align this with salesforce pledge ? https://www.salesforce.com/company/sustainability/

Thanks.
