“…In the scholarship on global climate governance, a number of concepts and terms have been introduced to analyze how we have moved away from a single regime (the UNFCCC) consisting of predominantly state actors towards a more complex arrangement, such as regime complex (Keohane & Victor, 2011), networked climate governance (Bäckstrand, 2008), transnational climate governance (Andonova, Betsill, & Bulkeley, 2009;Bulkeley et al, 2014), transnational regime complex (Abbott, 2012;Widerberg & Pattberg, 2017), and polycentric governance (Jordan et al, 2015;Morrison et al, 2017;Ostrom, 2010). These terms describe the system, while terms such as international cooperative initiatives (Widerberg & Pattberg, 2015) and non-state climate actions (Chan et al, 2015) describe units of study within the system.…”
