Climate change, global warming, carbon emissions, carbon footprint and a whole bunch of other words you've probably heard people mention when worrying about the environment. What the heck is a carbon footprint, why does it need to be reduced, and how does one go about doing that, anyway?
Simply put, a carbon footprint of individuals, businesses, systems or other organizations is measured by its total emissions of greenhouse gas. The greenhouse gas total of carbon dioxide (CO2) and methane (CH4) emissions are measured by using a GHG emissions assessment or carbon accounting.
