The blue bars display data on mitigation investment ﬂows for four years: 2017, 2018, 2019 and 2020 by sector and by type of economy. For the 
regional breakdown, the annual average mitigation investment ﬂows for 2017–2019 are shown. The grey bars show the minimum and maximum level of global annual mitigation 
investment needs in the assessed scenarios. This has been averaged until 2030. The multiplication factors show the ratio of global average early mitigation investment needs 
(averaged until 2030) and current yearly mitigation ﬂows (averaged for 2017/18–2020). The lower multiplication factor refers to the lower end of the range of investment needs. 
The upper multiplication factor refers to the upper range of investment needs. Given the multiple sources and lack of harmonised methodologies, the data can be considered only if 
indicative of the size and pattern of investment needs. {WGIII Figure TS.25, WGIII 15.3, WGIII 15.4, WGIII 15.5, WGIII Table 15.2, WGIII Table 15.3, WGIII Table 15.4}
