A bus company in my town are misleadingly labelling their new hybrid buses as zero emission and electric when they are in fact 100% diesel powered and have normal levels of emissions. As an asthmatic who suffers serious negative health effects from exposure to air pollution I feel the bus company has a duty to label them correctly. I would like to force the bus company to change the signs, what law does this come under? Also, I am not a customer of the bus company but someone who is affected negatively by the emissions.
(I contacted Advertising Standards but it is not relevent as the advertising is on the product itself)
