👉 Emissions math involves calculating the total greenhouse gas emissions produced by activities like energy consumption, transportation, and industrial processes. It typically uses emission factors, which are coefficients that represent the amount of emissions (usually in metric tons of CO2 equivalent) per unit of activity (e.g., kWh of electricity, miles driven). For example, burning one megawatt-hour (MWh) of coal generates approximately 2.2 metric tons of CO2. To find total emissions, one multiplies the amount of activity by the corresponding emission factor. For instance, if a household uses 500 MWh of electricity annually and the emission factor is 2.2 tons/MWh, the total emissions would be about 1,100 metric tons of CO2. This method helps in understanding and quantifying the environmental impact of various actions, guiding efforts to reduce emissions and mitigate climate change.
