The design of international environmental agreements is not random, but driven by rather strategic considerations of their "masters:" the nation states (see Fearon, 1998;Leeds, 1999;Koremenos et al, 2001;Grigorescu, 2007;Lupu et al, 2014;Chiba et al, 2015;Tallberg et al, 2016;Rapport & Rathbun, 2020;Young & Stokke, 2020). An extensive body of research reports here that inter alia country features, characteristics of the environmental problem at hand, as well international influences all play a role in shaping institutional design (see, e.g., Murdoch et al, 2003;Bernauer et al, 2010Bernauer et al, , 2013Tallberg et al, 2016;Spilker & Koubi, 2016;Carbonell & Allison, 2015;Böhmelt & Spilker, 2016;Böhmelt & Butkutė, 2018;Wagner, 2001;Wangler et al, 2013).…”
