1 year ago I've developed a prototype operator which I demoed today at the Karmada community meeting. Thanks for having me!
It would be great to collaborate with the community to implement this as a production ready feature.

What would you like to be added:
I'd like to be able to use Karmada to move workloads to clusters at physical locations with lower carbon emissions.
Why is this needed:
Data centres consume 1-1.5% of global electricity usage according to the IEA. Energy usage from data centres is increasing rapidly. https://www.iea.org/energy-system/buildings/data-centres-and-data-transmission-networks
Carbon aware spatial shifting can reduce carbon emissions by moving workloads to regions with lower carbon intensity.
This paper presented at the HotCarbon 23 conference found a similar approach implemented using a global load balancer service could provide savings on average of 21%. https://hotcarbon.org/2023/pdf/a6-maji.pdf
Since Karmada already has powerful multi-cluster and multi-cloud scheduling capabilities it would be great to extend this to add carbon awareness.
