Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will make an estimate of the potential impact on greenhouse gas emissions of global adoption of the Bridge to Busan Declaration approach to the Global Plastics Treaty.

The UK has signed the Bridge to Busan Declaration - a political declaration which makes the case for an ambitious treaty that includes upstream measures to ensure sustainable consumption and production of primary plastic polymers.

The Organisation for Economic Co-operation and Development has modelled different policy scenarios for reducing plastic pollution to 2040, including a Global Ambition scenario, which simulates global action across the whole lifecycle of plastic, including on the production and consumption of plastic. This scenario could achieve a 41% reduction in plastics-related greenhouse gas emission levels compared with levels expected in 2040 under a business-as-usual policy course (1.7 GtCO₂e in 2040 versus 2.8 GtCO₂e in the baseline).
