The present study aims to estimate CO2 emissions from decommissioning of solar and wind power plants. Using a hybrid method that combines process and input-output analyses, the CO2 emission is calculated based on an average decommissioning cost, which is estimated from the detailed construction cost data for different types of power plants. For a solar photovoltaic power plant, the estimated CO2 emission at the demolition stage is 2.1 g-CO2/kWh (tentative value), which accounts for about 4% of life cycle CO2 emission including the construction, operation and maintenance stages.
