“…We gathered disclosure scores from the CDP regarding the year 2018. CDP data have been extensively used in the previous empirical literature as a proxy for carbon disclosure quality and have become an international standard (e.g., Cotter and Najah, 2012 ; Luo et al., 2012 , 2013 ; Stanny, 2013 ; Ben-Amar and McIlkenny, 2015 ; Liao et al., 2015 ; Grauel and Gotthardt, 2016 ; Ott et al., 2017 ; Ben-Amar et al., 2017 ; Ben-Amar and Chelli, 2018 ; Li et al., 2018 ; Hsueh, 2019 ).
