I had a great time at yesterday's Green IO Conference in London, hosted as part of the Apidays series.

It was busy but in a good way; everyone was friendly, pragmatic and willing to share their candid opinions.

Common themes (from presentations and conversations):

- Use of carbon offsets to back data centre sustainability claims increasingly considered greenwashing.
- Dynamic electricity pricing will become mainstream.
- How can we "lint" dependency/framework choice to suggest alternatives?
