“…However, evidence suggesting that CMS positively impact individual environmental behaviors exists (Froehlich et al, 2009;Tight, Vocat, Bristow, Pridmore, & May, 2007). For instance, Tight et al (2007) found that a 20 percent reduction in carbon emissions from landbased travel could be achieved by households when a CMS was used to summarize travel behavior and provide estimates of the carbon footprint resulting from changes in these behaviors. Nevertheless, many carbon calculators are not as effective as they could be due to weaknesses in usability, poor communication and presentation of carbon footprint calculations, limited social networking capabilities, absence of automated data inputs, and a lack of standard and transparent calculation methodologies (Bottrill, 2007;Froehlich et al, 2009;Padgett et al, 2008).…”
