I spoke to taxi drivers from Unite the union who are worried that Glasgow's Low Emission Zone, which comes into force in June, could decimate their industry.
Experts estimate that more than 1,000 black cabs could be removed from the road - which is going to have a significant impact on the city centre as well as groups like the elderly and disabled.
Drivers are facing significant challenges in ensuring that their vehicles are compliant so Glasgow City Council must give them more time to prepare.
