Carbon emissions from the steel industry
The steel industry produces about 3 billion tonnes of CO2 per year, accounting for 9% of the world's total.
The total amount of greenhouse gases directly or indirectly emitted by various industries during their production, operation, and transportation processes.
Carbon emissions from the cement industry
Carbon dioxide emissions from the chemical process of producing cement and concrete in the cement industry account for 7％ to 8% of global emissions.
Carbon emissions from the aluminum industry
Carbon emissions from aluminum production account for about 0.8% of global greenhouse gas emissions. There are two major types of greenhouse gases emitted during the aluminum smelting process, namely carbon dioxide (CO2) and perfluorocarbons (PFCs).
Carbon emissions from the aviation industry
Before the outbreak of the COVID-19 pandemic, the International Civil Aviation Organization (ICAO) projected that by 2050, carbon emissions from international aviation could double what they were in 2015.
