Introduction of CO₂ toll charging in Bulgaria

CO₂ Toll Charging in Bulgaria Is Coming Soon

What Carriers Need to Know and How TollPass Will Help You?

From 1 March 2026, important changes to the toll charging model for heavy goods vehicles over 3.5 tonnes in Bulgaria will come into effect. A new parameter accounting for the vehicle's carbon dioxide (CO₂) emissions will be added to the existing toll rates. This is part of European measures to reduce harmful emissions and promote greener road transport.
To prepare the sector, the Road Infrastructure Agency will activate a special online CO₂ calculator from 15 December 2025.

What Is the CO₂ Calculator?

The calculator allows owners and drivers of heavy goods vehicles to determine the CO₂ class of their vehicle by entering its technical information into the national database. The resulting CO₂ class will serve as the basis for calculating the new emissions component in toll charges after 1 March 2026.

How Is the CO₂ Class Determined?

Users must create a profile and enter the vehicle's data, using information from:

• the vehicle registration certificate (VRC)
• the certificate of conformity (COC)
• the customer information file (CIF)

CO₂ Classes – What Do They Mean?

• Class 1 – for vehicles with a first registration date before 1 July 2019. They automatically fall into this category and are not required to be registered in the calculator. This is the group with the highest emissions and results in the application of the highest CO₂ component.
• Classes 1–4 – for vehicles over 3.5 t registered on or after 1 July 2019, with internal combustion engines. The assigned CO₂ class is valid for 6 years from the vehicle's first registration, after which it is reassessed.
• Class 5 – for zero-emission vehicles, including electric and hydrogen-powered ones.

Why Is a CO₂ Component Being Introduced in Toll Charges?

The new rules implement Directive (EU) 2022/362 and aim to:

• reduce harmful emissions from road transport
• improve ambient air quality
• encourage the use of greener vehicles
• introduce uniform European principles for road tolling

How Will TollPass Support Carriers?

As a national service provider, TollPass will offer:

• a convenient online CO₂ calculator for vehicles and submission of data to the national system
• verification that the CO₂ class has been entered correctly
• integrated tools for tracking emissions classes
• information and assistance in preparing for the new toll charging model

Our customers will receive timely reminders and guides for correctly entering data, to avoid being automatically assigned to the lowest emissions class.

The CO₂ component is an important step towards the modernisation of road tolling and sustainable transport. Carriers have ample time to prepare – and TollPass will be their reliable partner every step of the way.
