“…Moreover, this unjustified difference of performance variables was also present in studies with specific goals, such as papers with a greenhouse gas focus (see Dragomir [94], Wang et al [101], Misani and Pogutz [103], and Trumpp and Guenther 2015 [71]) or papers that focused on a financial crisis period (see Gallego-Alvarez et al [97], Muhammad et al [104], Muhammad et al [105], and Trumpp and Guenther [71]). Furthermore, with reference of specific industrial sectors analyzed (Table 3, third column), we recognize a non-homogeneity of variables considered to measure EP and BP (Table 3, second and third columns): e.g., López-Gamero et al [77], Molina-Azorín et al [50], and Trumpp and Guenther [71] in services sector; Zeng et al [84], Figge and Hahn [70], Fuji et al [63], and Sánchez-Medina et al [106] in manufacturing sector; Kranjc et al [73], and Galdeano-Gómez [74] in food sector.…”
