Background information

The Portuguese Government has issued a set of measures with the objective to support families and consumers in general, amidst the rising prices of fuel and other energy products, as a consequence of the COVID-19 pandemic and the further exponential increase in energy prices as a consequence of the war in Ukraine.

The present Ordinance is one of the several measures approved by the Portuguese Government to support citizens and families during the current period of rising energy and fuel prices.

The Law 82-D/2014, of 31 December, which approves the Reform of Green Fiscal Affairs, adds article 92 A, which determines that some fuel and energy products are subject to an addition on the emissions of CO2 (also known as carbon tax). This measure freezes the value of the tax addition, setting it to the value practiced in 2021.

Content of measure

The Ordinance 315/2021 of 23 December suspends the update of the tax addition on carbon emissions until 31 March 2022. This measure is extended by the Ordinance 118/2022 of 23 March, until 30 June 2022. This measure has additional extensions with the Ordinance 167-A/2022, of 30 June (extends measure until 31 August 2022), and Ordinance 217-A/2022 of 31 August (extends measure until 2 October 2022). On 5 September the Government announced that the suspension of the update of the tax addition on carbon emissions will continue until the end of the year (Government Press Release, 5 September 2022).

The measure maintains the 2021 tax addition on carbon emissions, in the value of €23,921 per ton of CO2, in the terms set by the Ordinance 277/2020, of 4 December. In practice, this measure avoids a rise of 5 cents per litter of fuel (both gasoline and diesel). The value of the addition tax is set annually on the basis of the prices of auctions of licenses of gas emissions of greenhouse effect, held within the framework of the European Commerce of License Emissions (Comércio Europeu de Licenças de Emissão (CELE)).

According to the newspaper Dinheiro Vivo this measure has a cost of €93 million, until the end of March 2022 (Dinheiro Vivo, 22 October 2021). Additionally, the extension of the measure until the end of the year will represent an effort of €537 million (Dinheiro Vivo, 6 September 2022).
