“…From the 1990s, pro-environmental behaviour has been operationalized as conservation behaviour (Castro, Garrido, Reis, & Menezes, 2009), recycling (Saphores et al, 2012), transport use (Eriksson, Garvill, & Nordlund, 2008), household consumption, (Ole, 2008), household waste separation (Tadesse, 2009). Meanwhile, research has addressed not only consumption habits but also purchase patterns in different areas, such as buying green products (Coad, De Haan, & Woersdorfer, 2009;Ramayah, Lee, & Mohamad, 2010), eco-labelled food products (Grankvist & Biel, 2007), electrical appliances (Gaspar & Antunes, 2011) and plastic bags (Jayaraman, Haron, Sung, & Lin, 2011). A whole variety of pro-environmental consumer behaviours are thus analysed in different studies.…”
