Euro-4 :: Honda Cars Philippines, Inc.

	Euro-4 level is the second strictest emission measurement of the European Emission Standards. To reach this level, vehicle emission of Carbon Monoxide (CO), Hydrocarbon (HC), Nitrogen Oxide (NOx) should be 1 g/km or below (pls see table below).
	European Emission Standards for Gasoline Fueled Passenger Cars (in g/km) Euro 1 and 2 level engines do not separate the hydrocarbon and nitrogen oxides. Euro 3, 4 and 5 level engines separate the hydrocarbon and nitrogen oxides. **US and Japan have their own emission standards equivalent to Euro-5 level of the European Emission Standards.
	All new vehicles sold in European countries should meet at least Euro-4 level, otherwise they will not be allowed on the roads. Some countries in Asia & Oceania such as Australia and India have adopted the Euro-4 level conformity. The Philippines on the other hand has adopted only up to Euro-2 level.
