Which of the following describes an emissions factor?

An emissions factor is defined as a value that quantifies the amount of pollutants released into the atmosphere as a result of a specific activity or process, typically expressed in terms of mass per unit of activity (e.g., grams of CO2 emitted per kilowatt-hour of electricity generated). This measurement is crucial for assessing the environmental impact of various activities and is often used in carbon accounting and emissions reporting.

By quantifying emissions associated with specific processes or fuels, emissions factors enable organizations and policymakers to estimate total emissions and track progress towards sustainability goals. They help in comparing the efficiency and environmental performance of different technologies, processes, or operational practices. Being aware of emissions factors allows for informed decision-making regarding emissions reductions, clean technologies, and regulatory compliance.
