How are emissions calculated?
Environmental protection agency (EPA) in the US uses several methods to calculate emissions statistics. The first aspect is the amount of carbon dioxide (CO2) produced for each gallon of gasoline. Another aspect of EPA in emissions statistics is fuel consumption and light trucks. In addition, the number of kilometers of driven vehicles is determined. Finally, emission statistics include the effects of other greenhouse gases. Other agencies and governments around the world can use similar or alternative methodologies for calculating emissions statistics. In general, it is accepted by those who believe in a climate change caused by man, that the largest contributor to global warming and exhaustion of the ozone layer is CO2 emissions from cars, trucks and factories. Other greenhouse gases, such as CH4, N2O and HCFSstatism of Ision, also contribute to EM. They are usually emitted from the tail pipeline of cars and air conditioning leakage. CO2 is assumed to contribute about 95 percent of all greenhouse gasesand therefore it is the primary focus of emissions statistics. Gallon of gasoline usually produces about £ 19.4 (8.8 kg) CO2. This calculation is based on the value of gallon carbon content of gasoline, as shown in the US Code of Federal Regulations.
As soon as the amount of carbon made of gasoline is known, it is necessary to determine how many kilometers the car can travel on one gallon of gasoline. This is commonly known as fuel consumption and is represented by unit kilometers per gallon. EPA generates estimated fuel consumption for the city and driving on the highway.
The third part of emissions on CO2 emissions is the number of kilometers of cars and trucks will travel per year. It is generally assumed that all cars will travel about 12,000 miles per year. It is estimated that light trucks travel about 15,000 miles per year.
the final calculation for determining CO2 emissions from a passenger car isA little complicated. It uses the number of kilometers of driven vehicles and divides it with an average fuel consumption of a passenger car. This number is then multiplied by CO2 to Gallon. The resulting value is multiplied by 100 and divides 95. Finally, this value is divided 1000.
The average passenger car will emit 5.48 metric tons of CO2 per year. It assumes that the car travels 12,000 miles and has fuel consumption of 20.3 MPG. It also uses 8.8 kg CO2 when calculating.
