Int. J. Environ. Res. Public Health 2009, 6 696 emissions of fine particulates and other transport-related atmospheric pollutants (e.g. sulphur dioxide, nitrous oxide, carbon monoxide) other than CO2, of which some also have a greenhouse effect (e.g. nitrous oxide), as well as the reduction of health impacts related to air pollution, particularly in young children, the elderly, people with respiratory problems (e.g., asthmatics) or people with a heart condition [8-14]. Those population groups are also among the most vulnerable to health impacts from climate change [15]. Clearly, remote car starters encourage motorists to warm up their vehicles by idling the motor – a polluting habit with impacts on public health which becomes even more problematic with the increasing supply and demand for this type of technology in Canada [1]. The aim of this study was to examine diverse perceptions and individual characteristics associated with use of a remote car starter in winter (among other climate change related behaviors) through a survey carried out in 2005 in southern Québec (Canada) in the context of a research program on some climate change (CC) adaptation and mitigation strategies [16]. 2. Methods 2.1. Study Population and Sample The study population consisted of adults aged 18 years or older from the southern part of the Province of Québec south of the 49th parallel, namely all the health regions presented in Figure 1, with the exception of sub-arctic regions 10, 17 and 18.
