VDA#8

Many economies in developed countries have an effective impact on co2 emission. Almost all co2 emissions (about 96.5%) come from fossil fuel use. the most common types of fossil fules are coal, petroleum, natural gas, methane and propane. When these fuels are burned, they react with oxygen and produce carbon dioxide and the carbon stored in them is emitted almost entirely as co2.
The most important source of co2 emissions worldwide is caused by the transportation sector, which carries people and goods by cars, ships and others. The impact that transporting people and goods has on greenhouse gas emissions and climate change is so large that it is beyond emission from all industrial manufacturing.  On other main large impact on co2 emission are industries. Many manufacturing facilities directly use fossil fules to create heat and steam needed during various stage productions. Also their energy intensive activities use more electricity than any other sector.
