This question is not so easy to answer. In order to create optimal growing conditions for the plants, the sun is artificially simulated - that requires electricity. However, we use one of the latest vertical farming technologies: our low-voltage multispectral lighting requires less electricity than that of other farms.
Besides, we put a lot of focus on getting our energy from solar energy supplied by Greenman Energy as fossil fuels or other traditional energy sources account for most of the CO2 emissions.
