Biofuels and hydrogen powered bikes could feature in the future, says minister
The TT needs to work with the motorsport industry to ensure it meets sustainability targets in the future.

Organisers will be offsetting emissions in a bid to make this year's event carbon neutral.
But Dr Allinson says there needs to be a focus on zero or low emissions bikes in the future:
