2367.855 ÷ 3.7853 = 625.539 | BC ÷ K = B |

Each gallon of CNG is equivalent to 3.7853 liters of petrol, converted to liter gallons by using the formula. | |

625.539 × 125,000 = 78192448.418 | B × B |

CNG releases lead-free petrol at 125,000 BTU (produced thermal energy). Thus, using this formula, BTU BTU gasoline is obtained per gallon. | |

0.0781 × 19.35 = 1.513 | A |

Each gallon of CNG releases petrol equivalent to 19.35 tons of carbon, so this formula produces the amount of carbon released from the amount of consumed petrol. | |

1.513 × 1 | F |

Each hectare of fertile soil absorbs 1.8 carbons; in this formula the required land is obtained to absorb carbon. | |

0.841 ÷ 46,900 = 0.00001 | L ÷ P = EF |

In final stage, footprint per person is obtained by dividing required land for carbon absorption on city population. |
