In practice, customers will have to pay four cents for transparent plastic bags often used for fruit, vegetables or bread.

At issue is article 277 of OE2024, which creates a contribution "on light and very light plastic bags, produced, imported or acquired in the territory of mainland Portugal, as well as on light and very light plastic bags sent to the country".

"For the purposes of the provisions of this chapter, very light plastic bags are understood to be those purchased in the bulk sale of bakery products, fresh fruit and vegetables".

The contribution on these very light plastic bags is "0.04 (euros) for each very light plastic bag".

The Government also stipulated that bags that "are used in a social or humanitarian context, namely in the social distribution of food or in combating food waste" are exempt from this contribution.

"The contribution on light and very light plastic bags is the responsibility of the final purchaser, and economic agents in the commercial chain must pass on the economic burden of the contribution to their purchaser, as price", it is also mentioned.
