Why environmental laws are more strict in Maine state like California?

Question

Why the vehicle emission laws are more strict in Maine than 45 states.

How come Maine state dont let pass any vehicle emissions?

Answer 1

States with high populations (California is the state with the highest population) usually have tighter regulations on pollution. That's because with more people and industry there is a lot more pollution. Pollution from cars, trucks, businesses, etc. States like Montana or Wyoming have very small populations, so they don't have to have as many regulations. There probably aren't enough people living in those areas to affect the environment significanly at the rate their population, industry, and pollution is growing (if it is growing at all).

I was reading the second part of your question and I have to say that I don't really understand. Some states just have voters more worried about pollution from auto emissions. Maine must be one of those states. This will usually cause fuel providers to put additives in the gasoline to lower harmful emissions. This will, unfortunately, usually raise the cost of gas in your area.

Answer 2

States with high population density often adopt the CA emissions standards. Although ME isn't high density in most of the state, they agreed to adopt them due to their proximity to MA which has a real problem. Many MA drivers were registering their cars in ME to avoid the emissions test. Down Easterners are pretty environmentally keen and had little problem with going along with MA to try to clean things up.
