"Cars, public or private, are not the solution [to carbon emissions.]

South China Morning Post: "Such a reduction is only possible through the widespread adoption of public transport such as double-deck buses carrying 138 passengers that occupy only 12 metres of road space versus the same space with two cars carrying eight passengers at best. As with most densely-populated world cities, Hong Kong has a limited amount of road space for the number of users requiring it so it must be used as intelligently and efficiently as possible. Cars, public or private, are not the solution."
