Climate and changing cars

In recent news, the world is now coming together in Copenhagen to tackle CO2 emissions.  CO2 levels affects the climate changes that we are now facing.  What has that got to do with changing cars?  Here is a food for thought - think of the energy and materials needed to produce the parts - all those need to get their power somewhere. 

So changing cars is not just about finances, it is also about being a good steward of the earth given to us.  I will hold off (thoughts of) changing cars as long as possible. 

Have a blessed day!
