Final answer:
Carbon footprinting measures greenhouse gas emissions resulting from human activities or product manufacture and use. It is a simpler process than water footprinting.
Step-by-step explanation:
Carbon footprinting is a method used to measure the volume of greenhouse gas emissions, which includes carbon dioxide, resulting from human activities or the production of a product. It provides a quantitative measure of the environmental impact of an individual, community, or business in terms of their greenhouse gas emissions. Carbon footprinting can measure both direct consumption, such as the emissions from product use, and indirect consumption, such as the emissions from the manufacture of a product. It is also important to note that carbon footprinting is a relatively simpler process compared to water footprinting, which involves calculating the water usage associated with a product or activity.
