Despite triumphant reports and numerous messages from metallurgical companies about environmental upgrades, the total amount of greenhouse gas emissions in the global metallurgical industry has practically not decreased. This is evidenced by World Steel Association data for the last three years.
It can be seen from the report that CO2 emissions per ton of steel produced in 2017 averaged 1.84 tonnes, and in 2019 - 1.83 tonnes. At the same time, energy consumption does not decrease either: in 2017, 19.85 GJ was spent on the production of one ton of steel, and in 2019 - 19.84 GJ.
Taking into account that the world steel production in 2018 increased by 4.6%, and in 2019 grew by another 3.4%, it can be concluded that the total amount of greenhouse gas emissions from the metallurgical industry has increased significantly over the past three years.
The document also notes a sharp reduction in injuries in metallurgical industries and an increase in investment in new processes and products.
The World Steel Association uses 8 indicators to measure key aspects of the economic, environmental and social sustainability of the steel industry. The data was provided by 104 steel companies, which account for 1.1 billion tonnes of steel, accounting for almost 60% of the world's raw steel production.
