At Igniting Minds Organization, we strive to provide accurate and insightful information regarding the environmental impact of various activities facilitated through our platform. It's essential to note that the calculation of environmental impact parameters, including CO2 footprint, Land footprint, Water footprint, and Plastic footprint, for eco-activities such as transportation, food & beverage consumption, plastic consumption, among others, is based on established methodologies and data sources.
However, it's crucial to recognize that these calculations involve certain assumptions and approximations due to the inherent complexity and variability of environmental systems. Factors such as regional variations in resource use, technological advancements, and changes in consumer behaviour can influence the accuracy of these calculations.
Therefore, while we endeavour to provide reliable estimates, users should interpret the results with caution and consider them as indicative rather than absolute values. Additionally, we encourage users to consult multiple sources and conduct further research to gain a comprehensive understanding of the environmental impacts associated with their activities.
By acknowledging these limitations and uncertainties, we aim to promote transparency and informed decision-making regarding environmental conservation efforts. We remain committed to refining our methodologies and incorporating the latest scientific insights to enhance the accuracy and reliability of our environmental impact assessments.
To accurately determine the amount of CO2 absorbed by trees, two critical measurements are taken directly from the tree: its diameter, measured in centimetres, and its height, measured in meters. These measurements are essential for calculating both the Above-Ground Biomass (AGB) and Below-Ground Biomass (BGB). The calculation of these biomass values is based on a specific formula that incorporates these two parameters.
AGB = 0.25 x D2 x H
The overall green weight of the biomass is estimated to be 120% of the AGB value, based on the assumption that the BGB, which comprises the tree’s root system, accounts for approximately 20% of the AGB. Therefore, BGB can be calculated as follows:
BGB = 0.2 × AGB
From these formulas, we can calculate the total biomass of a tree:
Total Biomass (TB) = AGB + BGB = AGB + 0.2 x AGB = 1.2 × AGB
On average, a tree consists of 72.5% dry matter and 27.5% moisture content. To calculate the tree’s dry weight, we multiply the total biomass by 72.5%:
Total Dry Weight (TDW) = TB × 0.725
Carbon makes up 50% of the total dry weight. Therefore, the total carbon content in the tree is:
Total Carbon (TC) = TDW × 0.5
To find the CO2 equivalent sequestered in a tree, we use the molecular weight ratio of CO2 to Carbon. CO2 has one molecule of Carbon and two molecules of Oxygen, with atomic weights of 12u for Carbon and 16u for Oxygen. The ratio of the weight of CO2 to Carbon is 44/12 = 3.67. Therefore, to determine the weight of CO2 sequestered in the tree, we multiply the weight of carbon in the tree by 3.67:
CO2 weight = TC × 3.67
It is important to note that the CO2 weight calculated above represents the CO2 sequestered over the entire lifetime of the tree. To ascertain the annual or yearly rate of CO2 sequestration, divide the total weight of CO2 absorbed by the tree’s age.
At Igniting Minds Organization, we are committed to providing accessible and actionable information on carbon sequestration by trees. As a part of this effort, we have approximated the value of CO2 sequestration for trees to 650 grams per day for all species. This approximation allows for simplicity and ease of understanding while still conveying the significant impact of tree planting initiatives on reducing atmospheric carbon dioxide levels. Please note that this value is an estimate and may vary based on various factors such as tree species, age, environmental conditions, and geographical location.
