I'm not sure that offsetting would be ok - it's generally viewed pretty poorly and the most widely accepted Net Zero standard (https://sciencebasedtargets.org/), doesn't allow it.
I think it depends on what they want to be net zero - is it the construction or the operation of the stadium, or...
A mate and I are coming to Burton and then need to get the train back to London.
Last time I tried to get the bus it was a bit of a nightmare, they were all full and didn't manage to get one for ages.
Is there a better way? Maybe a taxi from bullnose?
All advice welcome!
