The meeting was held at the British Museum and attended by more than 100 transport professionals.
It also called on the government to put more cash into encouraging public transport alternatives to the car and to do more to encourage public transport operators to use fuel from renewable sources.
To encourage existing green drivers, the meeting called on the government to set a mandatory target for sales of carbon free vehicles by 2020. And new targets should be imposed to cut greenhouse gas emissions from surface transport.
The 10 point plan was welcomed by the Campaign for Better Transport (formerly Transport 2000) but a spokeswoman told NCE that cutting the amount of cars on the road was more important than technological solutions.
"Putting the emphasis on technology is not the answer," she said. "Ultimately the government has got to grasp the nettle and reduce traffic on the road and invest more in the country's rail system."
