Greenhouse Gas Emissions (GHG)
Greenhouse gas emissions (GHG) are gases that are released into the atmosphere and trap heat, contributing to the greenhouse effect and global warming. The most well-known greenhouse gas is carbon dioxide (CO2), which is released through the burning of fossil fuels (such as coal, oil, and natural gas), as well as through the deforestation and land use changes. Other GHG include methane, nitrous oxide, and fluorinated gases.
GHG are emitted into the atmosphere through both human activities and natural processes. Human activities that contribute to greenhouse gas emissions include the burning of fossil fuels for electricity, transportation, and industrial processes, as well as the production of certain industrial chemicals, and the raising of livestock. Natural sources of GHG include the decomposition of organic matter, and the emission of gases from wetlands, rice paddies, and other natural systems.
Measuring and reporting greenhouse gas emissions is an important part of understanding and reducing their environmental impact. Governments and organisations around the world use various methods to measure and report greenhouse gas emissions, including the use of emission inventories and accounting frameworks. By understanding and reducing greenhouse gas emissions, we can take steps to mitigate the negative impacts of climate change and protect the environment for future generations.
