Briefing
The Instituto Nacional de Estadística (INE) published preliminary results for the “Cuenta de impuestos ambientales” for 2025 on 5 November 2026 . According to the results, revenue from environmental taxes in Spain in 2025 amounted to 27,710 million euros, an increase of 7.5 per cent compared with 2024. At the same time, these taxes accounted for 6.6 per cent of total tax revenue in the Spanish economy, 0.2 percentage points less than in 2024. The INE note explicitly states that the data are provisional and may be adjusted in future revisions.
By sector, 80.1 per cent of environmental taxes in 2025 came from energy taxes, 11.4 per cent from transport taxes and 8.5 per cent from taxes on pollution and resource use. Energy taxes rose by 12.0 per cent compared with 2024, reaching 19,237 million euros. Transport taxes fell slightly (-0.3 per cent), while taxes on pollution and resources rose by 3.3 per cent.
Households paid a total of 11,758 million euros in environmental taxes in 2025, an increase of 1.4 per cent on the previous year; they therefore accounted for 42.4 per cent of the total. Of the tax burden on households, 72.6 per cent was attributable to transport, 42.0 per cent to energy and 6.0 per cent to pollution and resource taxes. Businesses paid the remaining 57.6 per cent; manufacturing industry and transport and storage were the largest contributors.
Methodologically, the INE classifies environmental taxes according to the system of national accounts and defines them by a tax base with clear environmental relevance. The publication includes detailed tables by tax type and economic sector, as well as a note on the methodology used. For further analysis of causes, distributional effects or sectoral impacts, the INE refers readers to future analyses and the complete datasets in INEBase.
