Carbon Offseting calculations

Carbon Offseting calculations

Every day we cause carbon dioxide to be emitted into the atmosphere through the use of fossil fuels, for example by our modes of traveling; airplane, cars, etc.

To offset our emissions trees are a good counterbalance as they ‘inhale’ or absorb carbon dioxide and ‘exhale’ or emit oxygen. The amount of CO2 absorbed varies between trees and the environment which they are in, but on average a large tree will absorb approximately 20.3kgs per year over a 40 year lifespan.

The tree offset calculation below is based on a tree planted in the humid tropics absorbing on average 20.3 kg. of carbon dioxide annually over 40 years, therefore each tree will absorb 1 ton of CO2 over its lifetime.

  • 1 metric ton = 1000 kilograms
  • 1 large tree will absorb approximately 20.3 kgs of carbon dioxide / year for over a 40 year lifespan (on average).
  • 1 seed/plant = THB 500 with lifespan monitoring.
  • Prices in THB based on 1 USD = 36 THB.
