I gathered to this blog post information about Azure Cloud sustainability and how you can estimate the carbon emissions associated to your Azure services usage.
About carbon dioxide CO2 emissions in general
Carbon dioxide (CO2) is a greenhouse gas which heavily influences for global warming and climate change. Burning fossil fuels and deforestation, have significantly increased the amount of CO2 in the atmosphere. This has been leading to rising temperatures, changing weather patterns, and other negative impacts on the environment.
The success of Industrial Revolution in the late 18th century was heavily dependent about usage of fossil fuels such as coal and oil. Basically, Carbon dioxide (CO2) emissions have been increasing since the Industrial Revolution.
Carbon dioxide (CO2) emissions are still increasing in global level so there is still a lot of work to do. Most of the countries and different organizations & corporations and individuals are already committed to decrease these carbon emissions.
The European Parliament has adopted the European Climate Law, which raises the EU’s 2030 emissions reduction target to at least 55% from 40% and makes climate neutrality by 2050 legally binding (Reducing carbon emissions: EU targets and measures, 2023)
Microsoft has declared that Azure has committed to focus on four key areas of environmental impact to local communities—carbon, water, waste, and ecosystems (Azure Sustainability).
- 100% renewable energy by 2025
- Water positive by 2030 replenish more water than we consume by 2030.
- Zero-waste certification by 2030.
- Net-zerodeforestation from new construction.
How to find more sustainability information in Azure Region level?
Microsoft has created a Azure global infrastructure experience tool which visualizes locations of Data centers in a globe and provides interesting sustainability information. This tool also visualizes Microsoft's participation to sustainability projects such as building wind or solar capabilities.
Each Azure Region has an own sustainability fact sheet which presents interesting and useful information about Microsoft's local commitments in the area in those for key areas (mentioned in the above). You can find the sustainability fact sheet in the right panel when you have clicked one specific Region.
How to estimate the carbon emissions associated to your Azure services usage?
Currently there are at least two solutions available to estimate the carbon emissions associated to your Azure services usage.
Emissions Impact Dashboard for Azure
Emissions Impact Dashboard for Azure is a Power BI App which calculates your carbon emissions from the Azure cloud usage. Dashboard provides multiple views to carbon emission data such as emissions by Azure Service and emissions over the time. App has also an interesting view which explains thoroughly what kind of calculation methodologies are used to present the data.
Cloud for Sustainability API
Emissions Impact Dashboard for Azure is a ready and robust reporting tool to cloud carbon emission data. Cloud for Sustainability API provides an API level access to carbon emission data related to your Azure and also Microsoft 365 usage. Especially, if you need create a custom reporting or use the emission data e.g. to control your processes then Cloud for Sustainability API is your choice.
Currently Cloud for Sustainability API is in public review and you need to request access to it from here.
You can find more information about the API from these links:
Green software development
The purpose of green software development is to develop software so that carbon emission reduction is considered in the architecture and processes. If you're interested about green software development I would suggest you to follow The Green Software Foundation. The Green Software Foundation is a non-profit organization with the mission to create a trusted ecosystem of people, standards, tooling and best practices for green software.
The Green Software Foundation has developed Carbon Aware SDK which helps you build the carbon aware software solutions with the intelligence to use the greenest energy sources. This enables that you can run your software when the electricity is clean and do less when the electricity is dirty, or runs in a location where the energy is cleaner (Carbon-Aware SDK)
