GHG Calculation Tools

The GHG Calculation Tools intends to facilitate the calculation of N2O emissions from adipic acid production, direct CO2 emissions from the production of ammonia and Nitric acid tool allows the N2O emissions from nitric acid production. The tool also calculates any emissions reductions associated with the use of emissions control technologies. The guideline is intended to facilitate the measurement and reporting of direct greenhouse gas emissions from the production of adipic acid, ammonia, and nitric acid at the company and plant level. A step-by-step approach is presented that covers each stage of the calculation process from data collection to reporting. This tool is based on the emission factor-based methodology, which multiplies activity data (the amount of ammonia produced by a facility) by an emission factor that describes the amount of energy required to produce one ton of ammonia. The resulting estimate of energy consumption is combined with carbon content data to calculate the CO2 emissions generated by a plant's ammonia production.

GHG Reduction Potential

The tool allows identifying emission sources in the production of adipic acid. With the tool, there is no direct reduction. However, it sets the first step for a business to calculate CO2 and NO2 emissions, allowing it to develop a strategy to suppress or reduce emissions where possible. The guideline includes a multi-step approach that allows reporters to choose between simple and more advanced approaches to measuring N2O emissions from nitric acid production. The most accurate emissions data can be obtained by directly monitoring N2O emissions. The use of site-specific emission factors is the second best solution. The least accurate results are obtained by using standard emission factors.
