The stage that made the catalytic converter and unleaded petrol compulsory in practice. One set of limits covered both fuels, with hydrocarbons and nitrogen oxides measured together rather than separately. The only particulate limit applied to compression ignition engines.

Common questions
- When did Euro 1 come in?
- It applied to new car registrations from 31 December 1992, having applied to new type approvals from 1 July 1992. The registration date is the one that matches a DVLA record, so it is the one to use when reading a car's age against a standard.
- Is a Euro 1 car allowed in a clean air zone?
- A petrol car does not meet the Euro 4 pass mark and a diesel does not meet the Euro 6 pass mark, so a Euro 1 car of either fuel pays the daily charge.
- What does Euro 1 actually limit?
- The stage that made the catalytic converter and unleaded petrol compulsory in practice. One set of limits covered both fuels, with hydrocarbons and nitrogen oxides measured together rather than separately. The only particulate limit applied to compression ignition engines.
- Where is the standard written on my car?
- Section D.2 of the V5C. It is also on the certificate of conformity the manufacturer issued, which is the document an operating authority will accept if a zone has the wrong figure on record for your car.
