What I am looking for is an industrial dataset of environmental metrics that contains possible green house gas emission values like CO2 or CH4 preferably along with some environmental values like temperature and humidity of the environment where the actual sensor has been placed.

This is a good example of a similar dataset http://iot.ee.surrey.ac.uk:8080/datasets.html#pollution

However, it originates from city placement (not industrial setting) and it does not directly contain environmental circumstances like temperature and humidity.
