I'm by no means a expert on this stuff but found it while researching Hedera. It basically tracks transactions and data across the Hedera Hashgraph network. I signed up and searched for the Tymlez, its continually updating. At the moment there are 54 transactions showing from the 15/3 till today.
They show 3 types: Track carbon emission, Track carbon reduction and Track carbon forecast.
I can't see much more detail in each transaction apart from it saying" succesful" and the time taken averages about 10 sec so pretty close to what is advertised by Hedera.
I'm presuming that this is the dummy billing process that Tymlez is demonstrating with the companies in the trial as it collects the emissions data for them.
I'm not sure if I'm interpreting it all correctly and someone with better technical knowledge may have some input but I'm keen to hold till there is a announcement from these trials which shouldn't be too far away.
