The Global Scope 3 Problem
Emissions by industry are divided into three scopes->
Scope 1: Direct emissions from operations under a facility's control
Scope 2: Indirect emissions from the usage of electricity, cooling purchased from third parties, etc
Scope 3: Supply-chain emissions covering procured products, transport of suppliers and business travel, etc. (Indirect Emissions)
In essence, one company's scope 1&2 is another company's scope 3.
Scope 3 emissions can account for more than 80% of a company's overall emissions. On average, it is 11.4 times greater than a company's direct emissions. Globally, Upstream scope 3 emissions are estimated to be about 23 Gigatons, making it more than the emissions of the top 5 emitters - India, Russia, China, US, Brazil combined.
