Growing Carbon Footprint of Plastics

After analysing the global plastics value chain, ETH researchers have revealed that the impact of plastics on climate and health is bigger than originally thought due to the increased use of coal for process heat, electricity and as a raw material in production.

Plastics are useful, cheap and extremely popular. Global demand for them has quadrupled in the last forty years and is expected to continue to rise, with negative consequences for the environment and human health. The public is aware of the environmental harm caused by plastics, particularly at the end of their life cycle, such as when they release greenhouse gases and air pollutants when burned, or pollute water and soil in the form of microplastics.

Research into the global environmental impact of plastics has also focused primarily on the disposal phase. There are few studies about the production of plastics, which also affects the climate and air quality. However, such an in-​depth analysis requires detailed information about supply chains and processes in order to trace the relevant material and energy flows.
