Wan Junaidi: 'Kap chai' ban proposal must be backed by research

KUALA LUMPUR: The suggestion to ban “kap chai” motorcycles from entering the city centre in order to reduce carbon emissions needs to be backed by scientific research, said the Natural Resources and Environment Ministry.

Responding to Federal Territories Minister Datuk Seri Tengku Adnan Tengku Mansor's suggestion that small motorcycles be disallowed from entering the city, Minister Datuk Seri Dr Wan Junaidi Tuanku Jaafar said bikers weren’t the biggest cause of pollution.
