Excise clearances of marked gas oil, otherwise known as green diesel, were 1.2% higher in 2025 when compared with the previous year, the Central Statistics Office (CSO) said.

The latest data shows that green diesel excise clearances increased to 1.1 billion litres in 2025.

Clearances for green diesel in December 2025 stood at 78 million litres, which is up from 60 million litres in the same month in 2024.

However, the December 2025 figure is down from 82 million litres recorded in November 2025.

Green diesel is primarily used for off-road purposes such as agriculture and the heating of larger buildings.

Dr. Robert Stapleton, statistician in the CSO Climate and Energy Division, explained that "clearances are the duty paid on the quantity of oil removed from bonded warehouses and provide a proxy for sales".

The data also shows there was a 5.4% rise to 1.1 billion litres in unleaded petrol excise clearances when comparing last year with 2024.

This was the highest annual excise clearances for unleaded petrol since 2017.

The CSO noted that the figure was 42.5% lower than the unleaded petrol clearances figure of 2 billion litres reported in 2000.

Excise clearances of unleaded petrol in December 2025 were 99 million litres, compared with 91 million litres in December 2024.

Autodiesel clearances were 3.7% lower in 2025 compared with the previous 12 months.

The lowest annual excise clearances for autodiesel since 2021, the CSO said.

In 2025, autodiesel clearances were 3.4 billion litres which was 71% higher than the figure of 2 billion litres recorded in 2000.

Autodiesel clearances in December 2025 were 286 million litres compared with 281 million litres in December 2024.

The data also shows that kerosene excise clearances, at 964 million litres, were 0.8% lower, compared with 2024.

Kerosene is mainly used as a home heating fuel.
