Operationalization of the nutrient reduction scheme follow up system (2015-2017)

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 is to:

  • streamline and quality assure the production of the assessment through development of an integrated software tool,

  • support the communication of PLC assessments due in autumn 2016 by ensuring transparent access to data, assessment results and methods

  • propose an operational procedure for expert verification and approval of corrected PLC data by the Contracting Parties taking into account automation, and

  • document the assessment calculations and communicate that with experts of the Contracting Parties.

These project aims fit well with the PLC strategy for future deliverables ("Strategy for future HELCOM assessments of inputs of nutrients and selected hazardous substances") agreed in general by HOD 48-2015.

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.
