I like this! I'm already using Pi Zero's like this for temperature sensing; adding a CO2 sensor sounds like a good enhancement!

  This would be a good application for a Pi Zero W (with WiFi) - if you want to collect the data in a central location. I've linked the CO2 sensor I used in another comment.

    Yep - Pi Zero W's for the sensors reporting to a Pi 3 for aggregation and reporting.
