I propose to take Questions Nos. 298, 299 and 300 together.

In relation to Question No 298 (Ref: 23147/25), I am advised by Revenue that the number of category A vehicles and revenue raised from the applied Nitrogen Oxide (NOx) emissions levy in 2023, 2024 and to the 31st of March 2025 is provided in the table below.

In relation to Question No. 299 (Ref: 23148/25), I am advised by Revenue that, based on the most recent full year data (2024),

• Doubling the NOx levy from €5 to €10 on the first 40 mg/km, increasing the rate from €15 to €30 on the next 40 mg/km to 80 mg/km and increasing the rate from €25 to €50 on the remainder, while maintaining the current maximum charge of €600 for petrol powered vehicles and €4,850 for diesel powered vehicles, is estimated to yield approximately €34.7m in a full year.
• Doubling the NOx levy whilst also doubling the maximum charge on petrol vehicles to €1,200 and €9,700 for diesel powered vehicles would raise €36.8m.
