Methodology for Quantifying Nitrous Oxide (N2O) Emissions Reductions through Reduced Use of Nitrogen Fertilizer on Agricultural Crops
The ACR Methodology for Quantifying Nitrous Oxide (N2O) Emissions Reductions from Reduced Use of Nitrogen Fertilizer on Agricultural Crops details requirements for quantifying greenhouse gas (GHG) emission reductions by reducing the amount of nitrogen used to fertilize crops. The methodology was jointly developed by Michigan State University (MSU) and the Electric Power Research Institute (EPRI).
The methodology is applicable to the Agriculture, Forestry and Other Land Use (AFOLU) sector, and is specific to Agricultural Land Management (ALM) project activities. The scope of this methodology is limited to on-farm reductions in N fertilizer rate associated with the management of N-containing synthetic and organic fertilizers that reduce net N2O emissions from annual or perennial cropping systems. Emissions reductions and crediting for project activities occur by reducing the N fertilizer rate during the crediting period, when compared to the baseline (pre-project) period.
During a project crediting period, adherence to Best Management Practices (BMPs) as they relate to the application of synthetic and organic N fertilizer at the cropping site is required. These BMPs are related to N fertilizer formulation (or N content of organic additions) and dates and methods of application. Project Proponents shall describe and justify in the GHG Project Plan how relevant BMPs have been adhered to.
Three project categories are eligible under this version of the methodology:
During a project crediting period, projects initially accepted for inclusion in Category 2 can be re-assigned to Category 3, should new data become available. A retroactive crediting mechanism is provided to incentivize the collection of N2O emissions data and the development of emissions factors compatible with IPCC Tier 2 methodologies.
Projects using this methodology must comply with all requirements of the ACR Standard, submit a GHG Project Plan for certification by ACR, and secure independent validation and verification by an ACR-approved third-party verifier.
