“…8 Although elasticities range a great deal depending on studies: 0.25 in north China (Liu et al, 2013) and 0.6 in the UK (Büchs and Schnepf, 2013). 9 In the identified studies, expenditure elasticities range from 0.84 to 0.94 for GHG emissions (Kerkhof et al, 2009;Girod and De Haan, 2010;Duarte et al, 2012;Roca, Serrano, 2007), from 0.64 to 1 for energy consumption (Lenzen et al, 2006), from 0.86 to 0.96 for acidifiant gases (Kerkhof et al, 2009;Roca and Serrano, 2007), and from 0.71 to 0.81 for eutrophicant pollutants (Kerkhof et al, 2009;Roca and Serrano, 2007). We can note a 1.42 expenditure elasticity level for smog-forming pollutants in the case of The Netherlands, which shows the necessity to conduct separate analyses for different pollutants (Kerkhof et al, 2009).…”
