    The “carbon inventory” allows, once completed, to know where the cost increases would be if a carbon tax came into force. For example, the company “Smith and sons” sells biscuits. It realizes that for every ton of biscuits sold, there is roughly one ton of carbon equivalent of greenhouse gases that go into the atmosphere, corresponding to :

    Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy-saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in

    Data selection for background air. In 1957 Dave Keeling, who was the first to make accurate measurements of CO 2 in the atmosphere, chose the site high up on the slopes of the Mauna Loa volcano because he wanted to measure CO 2 in air masses that would be representative of much of the Northern Hemisphere, and, hopefully, the globe. That goal has not changed.
