This methodology may be used by project developers to generate carbon credits by utilizing algae-integrated treatment systems for wastewater nutrient removal, thereby avoiding greenhouse gas emissions associated with the construction and operation of conventional nutrient removal infrastucture. By reducing nutrient loading of traditional treatment processes, algae-integrated treatment systems can effectively lower direct GHG emissions in subsequent treatment steps, while also minimizing energy-intensive operations and chemical use resulting in the avoidance of emissions. Project develops will calculate the reduction in GHG emissions associated with both reduced direct emissions and avoided energy and materials as compared to business-as-usual case where gray infrastucture would have been constructed.
