Overview
Lightweight plastic carrier bags (i.e., those with a wall thickness below 50 microns) are among Europe's top 10 littered items. They are often used only once, but take centuries to fully degrade in the natural environment.
Before this happens, terrestrial or marine animals ingest them, or they break into microplastics. Either way, they end up in the human and animal food chain.
This is why the EU introduced rules to deal with the problem of lightweight plastic carrier bags.

Background
The Plastic Bags Directive (Directive (EU) 2015/720) is a targeted legislative framework designed to address the unsustainable consumption and environmental impact of lightweight plastic carrier bags across the EU.
As an amendment to the Packaging and Packaging Waste Directive (94/62/EC), it specifically targets lightweight plastic carrier bags with a wall thickness below 50 microns — which are rarely reused and represent one of the most persistent sources of littering in Europe. The law obliges Member States to implement binding consumption reduction targets, mandatory pricing, or marketing restrictions.
Why do we have this law?
The directive was adopted in 2015 in response to severe public concern over the environmental footprint of single-use carrier bags. Lightweight plastic bags are often used for only a few minutes, yet take centuries to degrade fully in natural environments.
Because of their lightweight nature, they easily escape waste management systems and become marine or terrestrial litter. Once littered, plastic bags harm wildlife through ingestion and entanglement, and gradually fragment into persistent microplastics that enter animal and human food chains. The law was introduced to shift consumer behaviour away from a throwaway culture toward reusable alternatives and resource efficiency.
Alignment with other EU policies
The Plastic Bags Directive operates in tandem with broader EU waste and environmental law. It acts as a specialised instrument within the Packaging and Packaging Waste Directive (94/62/EC) and complements the Single-Use Plastics Directive (Directive (EU) 2019/904), which enforces Extended Producer Responsibility (EPR), awareness campaigns, and litter clean-up requirements for very lightweight plastic bags (under 15 microns). It also contributes directly to achieving the environmental objectives of the Waste Framework Directive and the Marine Strategy Framework Directive.
Strategic basis
At the strategic level, rules on plastic carrier bags are an integral component of the European Green Deal, supporting key initiatives such as the EU Plastics Strategy and the Circular Economy Action Plan.
By driving a sustained reduction in plastic bag usage — capping annual national consumption at a maximum of 40 lightweight bags per person by 31 December 2025 — the directive directly supports the targets of the Zero Pollution Action Plan and the EU Biodiversity Strategy for 2030.
