By following the principles of the circular economy, greenhouse gas emissions are automatically reduced on a global scale. Climate change and the use of materials are closely linked. According to Circle Economy calculations, 62% of global greenhouse gas emissions (excluding those from land use and forestry) come from the extraction, processing and production of goods to meet society's needs; only 38% are emitted in the supply and use of products and services (Circle Economy, 2019). For example, emissions from industry in the European Union would fall by 56% in 2050 if the circular economy were to become a reality (SITRA, 2018). The reduction in emissions measured on a global scale will be even greater, because the European Union will no longer import primary raw materials from countries outside the Union, which will also reduce greenhouse gas emissions in those countries.
