Why and what is CO2 footprint calculation
Human activities are one of the main factors of greenhouse gas emissions. These increase the Earth’s temperature and are emitted from the use of fossil fuels in electricity and other by-products of production. Major effects of such actions mainly include climate change such as heavy precipitation and ocean acidification and warming. Climate change has occurred since the Industrial Revolution began in the 1820s. Due to human’s heavy dependence on fossil fuels, energy consumption and continuous deforestation, the amount of greenhouse gases in the atmosphere is increasing, making it more difficult to reduce the greenhouse gas footprint. However, there are many ways to reduce your greenhouse gas footprint, choose more energy-efficient eating habits, use more efficient appliances, increase the use of fuel-efficient cars, and save electricity.
Greenhouse gases (GHGs) are gases that increase the Earth’s temperature due to the absorption of infrared radiation. Although some greenhouse gases are natural, their production rate has increased due to humans. These gases are emitted from the consumption of fossil fuels in electricity, heat, and transportation, and are also released as byproducts of production. The most common greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and many fluorinated gases. Greenhouse gas footprint is the numerical amount of these gases emitted by a single organism. Calculations can be calculated from one person to the whole world.(https://en.wikipedia.org/wiki/Carbon_footprint)
