Car emissions have been on the rise in North America each and every year now for the past while and it appears that most people don't really want to pay attention to the issue at hand because more and more cars are on the road. The number one emission problem is CO2 and this is causing our atmosphere to crumble apart and it's not good for anyone. Everyone needs to begin to realize that they need to find alternative means of energy to power their vehicles or they need to stop using their vehicles as much.

With gas prices soaring higher and higher each day it should help keep some of the cars off of the road, and hopefully some of the big truck owners have to keep their trucks in park while the gas prices are high. Millions of trucks are sold each year and they are causing the most CO2 emissions into our air and it's causing the environment lots of problems which will cause us problems in the near future. If something isn't done about the amount people drive then soon something catastrophic is going to happen.

Almost all of the car manufactures in North America have announced that they will be releasing some sort of alternative energy model vehicle throughout the year.

It is believed that passenger cars generate maximum amount of harmful emissions that results in ecological imbalance. As car manufacturers started understanding the significance of ecological imbalance, they started hunting for ways and measure to reduce automotive emissions and protect environment.

Many Indian car manufacturers like Maruti Suzuki, Hyundai, and Honda are presently working on their green projects to ensure protection to the environment and even help car owners to reduce their fuel bills.

With the advent of technology, more and more advanced engines and alternative fuels are introduced to widespread the urgency of protecting the environment. These days, the trend of Liquefied Petroleum Gas (LPG) and Compressed Natural Gas (CNG) is increasing in the car industry. These alternative fuels are believed to reduce the burden on environment by producing lower level of emissions.

Some of the car manufacturers in India are also looking at water and air as alternative fuel. Though that’s a long way to go but if these are introduced as fuel in the Indian car market, the industry will definitely witness a new dawn.

The savings on gas over the long haul will be greater then the cost of the green cars being introduced to us and it means that buying a green car is the smart choice. It not only will help the environment for our children but it will also save us for having to buy gas off of crooks, who continually raise the price of gas.

Sir Mark, chairman of the United Nations' Foundation for the Global Compact, which raises fund to perk up sustainability, has this to say: "We need very tough regulation saying that you can't drive or build something less than a certain standard. You would be allowed to drive an Aston Martin – but only if it did 50-60mpg.

He noted making people with less fuel-efficient cars pay more in road and fuel tax would simply let the rich avoid taking responsibility for tackling climate change. "You can buy the roomiest, vroomiest car, as long as it meets the efficiency standard. We have driven a hybrid since 2001 and it is a beautiful piece of engineering," added Sir Mark, now a chairman of mining group Anglo American.

United Kingdom’s Society of Motor Manufacturers and Traders said Sir Mark's call was not helpful. "This is a really bizarre proposal. If we are trying to reduce emissions, it should not be confused by using other measurements. Our priority is to reduce, which will have the knock-on effect of improving engine efficiencies," the society’s spokesperson said.
