However, reducing emissions will quite quickly lead to reduced atmospheric levels of such substances. While reducing vehicle idling alone won't solve the climate change problem, it's a step in the right direction and it's easy to do! What is climate change?
If Canadian motorists avoided unnecessary idling for just three minutes every day of the year, it would prevent 630 million litres of fuel from being wasted and 1.
