Greenhouse gases, also known as GHG, are gases that trap heat in the atmosphere. These gases occur naturally and help keep the planet's temperature stable. However, human activities have increased the concentration of these gases. Once these gases are present in the atmosphere, they act as a blanket and trap heat. This trapped heat causes global warming which, in turn, leads to a changing climate.
GHG emissions data is collected and reported using a single metric for ease of understanding, which is metric tons of carbon dioxide equivalents or MTCDE. Emissions are reported according to their source and scope. There are three scopes of emissions - scopes 1, 2, and 3. Below are examples of emission sources for each scope.
