In 2007, HELCOM adopted a nutrient reduction scheme as part of the Baltic Sea Action Plan. In 2013, the nutrient reduction scheme was revised based on improved data and scientific models. The scheme consists of Maximum Allowable Inputs (MAI) and Country-Allocated Reduction Targets (CART) for nitrogen and phosphorus. Fulfilment of MAI and CART is to be followed up regularly through assessments.
The aim of the MAI-CART OPER project was to to operationalize the nutrient input assessment and
The implementation of the project was carried out by the Baltic Nest Institute in Sweden and the Danish Centre for Environment and Energy, and guided by the HELCOM Pressure Working Group consisting of the representatives of the Contracting Parties in HELCOM.
