The aim of the NAMA is to rehabilitate 19 arterial roads across the country, each of which is considered essential for the transport of people and goods, with a total length of 324 km. The NAMA concept is based on the fact that optimal maintenance of road infrastructure, notably the characteristics of its surface, can increase the efficiency of vehicular traffic and reduce fuel consumption and associated GHG emissions. This is achieved by reducing the rolling resistance of vehicles and preventing their unnecessarily slow movement. The need to rehabilitate road infrastructure is referred to in domestic transport, climate change and sustainable development strategies, and it is expected to have a transformative impact by enhancing mobility and economic development across the country. The submission to the NAMA Registry states that the National Implementing Entity is the Public Enterprise Roads of Serbia (PERS), and they are requesting a grant for EUR 139.33 million, which is the total estimated infrastructure cost.

Mitigation potential

The rehabilitation of the 19 different arterial road sections (collectively approximately 300km in length), each of which is deemed essential for the transport of people and goods. The optimal maintenance of road infrastructure, notably the characteristics of its surface, can reduce fuel consumption from vehicular traffic and associated GHG emissions.

The mitigation potential arises from the following points:

  • Traffic management and speed optimisation can cut CO2 emissions. Reductions in CO2 of about 20% can be obtained by techniques to mitigate congestion, manage excess speeds, and smooth traffic flow. Road maintenance projects can significantly reduce Carbon Dioxide Emission Rates.
  • An uneven road can increase fuel consumption by up to 12% relative to an even road. A rough macro-texture may increase fuel consumption by 7% relative to a very smooth macro-texture. Fuel consumption for a car may be influenced as much as 12% by road surface characteristics within the tested range.

Considering these factors, it was calculated that the project would mitigate CO2 emissions of 2,138 tons per year. Over a lifetime of 20 years, 46,360 tons of CO2 will have been mitigated.


Total costs EUR 146.33 million
Costs for preparation EUR 3.5 million
Costs for implementation EUR 142.83 million

The funding of the NAMA is planned primarily as a grant. A financing possibility as a loan will be subject to further negotiations with the implementing agency. The Development Bank of Serbia will be an intermediate in the financing process.

The financing costs for preparation of the NAMA will include technical support of the MRV process and capacity building within the implementing agency.



Monitoring activities will be conducted by PERS (or accredited laboratory), based on its ISO 9001:2008 certified quality management system. PERS will perform monitoring activities and measurement on the site.

The PERS will conduct quantification and monitoring of greenhouse gas emissions annually in accordance with internationally recognised methodologies. GHG calculation is not required by Air Protection Law of Serbia. In addition, the PERS will evaluate technically and financially feasible and cost/effective options to reduce or offset project-related greenhouse gas emissions during project design and operation. Installing devices which will allow measuring of CO2 emissions (possible link with Road Weather Information System – RWIS stations) is part of this project too. Results will be automatically collected and stored (in real time) in PERS Server.

PERS will prepare a Report that contains information on 1) the detailed result of the monitoring activities conducted based on the monitoring plan, 2) the result of emission reduction calculation based on the above mentioned methodology, and 3) any support received under NAMA scheme from Annex-I countries or international organisation regarding financial support, technical support, or support on capacity building.

  • Energy resources – rehabilitated road sections will ensure smooth traffic and will reduce fuel consumption.
  • Air – Due to the application of the modern technology and higher energy efficiency of the road, project will result in reduced emission levels of CO2, SOx and NOx, comparing to the existing conditions on proposed road sections.
  • Soil – Rehabilitation of proposed roads will be performed within the road right of way, so it would not be necessary to change the purpose of the land. In addition, waste disposal will be at the area anticipated for this purpose with application of the reclamation measures.


  • Life conditions improvement – Project implementation of such scope, lead up to the employment increase, as well as income increase, on the local and regional level.
  • Capacity increase – According to the work needs and modern equipment maintenance, strategic partner will provide training for the employees, as well as expertise and tools for local companies engaged on this implementation of the project during its operational life.


  • Economic development of the region – Rehabilitation of proposed road sections will ensure better traffic conditions on Serbian road network. It can significantly contribute to the economic development of those regions.
  • Rehabilitation of proposed roads will provide work for many domestic companies
