Carbon neutralA scenario in which the net discharge of carbon dioxide into the atmosphere is zero. Carbon neutrality can be achieved by planting trees so that CO2 emissions as a result of combustion would be offset by CO2 absorption by the plants. In the presence of water and light, trees convert CO2 into sugar and oxygen through the process of photosynthesis. The average tree absorbs 22 pounds of CO2 per year. Carbon neutral is also referred to as “net zero carbon.” It is also the result of balancing the amount of carbon dioxide produced from activities like driving a car or producing electricity with an equal amount offset by planting trees or supporting renewable energy from solar and wind. |
