Environmental Transportation Tips

Every time 1 liter of fuel is reduced, 2.52KGS of CO2 emissions can be reduced to the air.

The passenger car uses 36.65 liters of fuel per 100 kilometers. If a passenger car travels 300 kilometers per day, it is equivalent to emitting 277KGS of CO2.

If a passenger car travels for 300 days a year, it will emit 83 TON CO2.

 

According to environmental protection information, each tree can absorb about 12 kg of CO2 per year, and 83 TON of CO2. It takes about 7,000 trees to absorb it to balance.

 

If each tree occupies an area of 5 square meters, 7000 trees will occupy 35,000 square meters (about 5 standard football fields).
