SDG #9 is to “Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation”
Within SDG #9 are 8 targets, of which we here focus on Target 9.4:
By 2030, upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies and industrial processes, with all countries taking action in accordance with their respective capabilities
Target 9.4 has one indicator:
Indicator 9.4.1: CO2 emission per unit of value added
Carbon dioxide is an 80% share of all greenhouse gas emissions from the energy used to power industrial processes, so it’s the focus on this indicator.
As of 2018, the world emits 320 grams of carbon dioxide per dollar of value-added in the manufacturing sector. This figure hasn't unchanged since the most recent data around the adoption of the SDGs. The country with the most emissions per dollar of manufacturing value-added is Trinidad and Tobago with 1.16kg. Following is Mongolia with 1.09kg per dollar and North Korea with 1.18kg.
