It's deployed in a test network. The carbon footprint of this little experiment is negligible:
"This application would be able to run 'forever' - so long as there was some funds in an Ethereum account that could be used to run each 'step'.
However, the cost of Ethereum (and therefore 'gas') used to run smart contracts is so high that it would cost (in March 2021) over $80 just to register the smart contract, and to run a single 'step' of the game would cost over $2,000! No doubt that the code could be made more efficient and consume less resources, but hey that's just too much work for a concept app, so I have simply registered the contract on the Kovan test network instead, and use some 'fake' Ethereum to run the system. The app is the same, but it just points to the 'Kovan' test network instead of the Ethereum mainnet."
