The UK government is expected to slash its electric vehicle targets this week in a boost for car manufacturers.
The government's current rules state 80% of new cars sold in the UK must be electric by 2030, with new petrol and diesel cars set to be phased out and, by 2035, all new cars must be zero emission.
However, industry groups have called for "urgent relief", and the BBC reports the government has been consulting on lowering the 80% rule.
While the government says no decision has been made, a source told the BBC Downing Street would approach the issue in a "pragmatic and balanced" way.
A government spokesperson said: "We are committed to the phase out of all new cars relying solely on petrol and diesel engines by 2030, and to 100% of new car and van sales being zero emission by 2035, and our legally binding net zero targets."
The European Union opted to scrap similar plans, particularly sales of petrol and diesel cars from countries such as Germany with substantial car manufacturing industries.
