The Philippines is now following Euro 4 emission standard. To put things in perspective, North America and Europe have implemented Euro 3 in 2005. Clearly, we are behind when it comes to emission standard, which could be attributed to the country’s lack of resources.
Of note, the Philippines’ Department of Environment and Natural Resources (DENR) pushed for the implementation of the Euro 4 compliance in July 2015. However, a number of local oil companies and automotive manufactures stressed out that they prefer to follow the original timeline set by the Department of Energy (DOE), which is January 2016.
The upgrade from Euro 2 to Euro 4 reduces the toxic sulfur that comes out of the combustion engine by 450 parts per million (ppm), both on diesel and gasoline. Benzene, which is also considered harmful to humans, was also cut off by 4%. Standard CO emission permitted by Euro 4 on gasoline is 1.0g/km, while it's 0.5g/km for the diesel.
The local implementation of Euro 4 limit falls under the "Philippine Clean Air Act of 1999," which requires vehicles with Euro 4 fuel to comply with the standards issued by the DENR.
