Question

Explain how effective the modern machines are in combating pollution.

Answer 1

Unnecessary idling of cars, trucks, and school buses pollutes the air, wastes fuel, and causes excess engine wear. Modern vehicles do not require “warming up” in the winter, so there is no need to turn on the engine until you are ready to drive.

Reducing idling from diesel school buses prevents children from being exposed to diesel exhaust, reduces greenhouse gas emissions, and saves money on fuel. EPA's Clean School Bus Program includes information and resources that can help you reduce school bus idling in your community
