Pull away gently and keep the catalytic muffler good

To pollute less, pull away slowly without accelerating suddenly, don't keep low gears if not needed and change the catalytic muffler when it is old. With a cold engine, just started, the catalytic converter pollutes more, not less.

Word: Marmitta catalitica = a muffler that cleans the exhaust gases.
