The international norms that will help to regulate the amount of carbon dioxide released into the air as defined by the Clean Air Act are 0.010 gram/mile and 0.030 gram/mile for newer vehicles.
Kyoto protocol is the reason on which the international norms to regulate the emission of carbon dioxide is based. This protocol was negotiated in Dec 1997 at Kyoto, Japan and came into force on Feb 16th, 2005. It is an international treaty which extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC).

Euro II norms suggest that the aromatic hydrocarbons are to be contained at 42 %
Negative carbon dioxide emission is the opposite of carbon dioxide. The formula for carbon dioxide is CO2.
The best way of reducing emission of carbon dioxide is to use carbon-free or reduced-carbon materials
Emission.
Carbon dioxide is a greenhouse gas. It traps heat from the sun and prevents it escaping from the atmosphere. It makes the Earth a warmer place. In 2007 the US Supreme Court ruled that carbon dioxide was a pollutant and so the EPA had the right to regulate its emission from new cars.

In some cases the emission of a large amount of carbon dioxide can displace oxygen from the air. As a result, people and caught in the gas cloud can asphyxiate.

The most obvious effect is the emission of carbon dioxide.
The worlds carbon dioxide emissions from the use of fossil fuels has decreased since 2002. The United States has had the largest decrease in carbon dioxide emissions.
