Montenegro is approaching the provisional closure of EU accession Chapter 27 on Environment and Climate Change, but implementation of European environmental standards is expected to require investment exceeding €3 billion, according to Government estimates.
The financial requirement covers a wide range of environmental obligations, including wastewater infrastructure, drinking-water protection, waste management, landfill remediation, industrial controls, air quality, chemicals regulation, nature conservation, marine monitoring and climate measures. Environment Minister Damjan Ćulafić has identified the financial and technical requirements as one of the main challenges under Chapter 27. A detailed financial analysis of the required investments is still being prepared.
Government Adopts New Environmental Measures
On 28 May 2026, the Government approved proposed legislation on chemicals and environmental noise, along with the Marine Environment Protection Strategy until 2036. The three documents represent key elements of Montenegro’s efforts to meet Chapter 27 closing benchmarks and affect multiple sectors, including manufacturing, chemical imports, municipalities, airports, transport infrastructure, coastal development, ports, shipping and tourism.
The environmental transition is not linked to a single project or regulation but represents the combined cost of bringing multiple systems into compliance with EU standards.
Chemicals Rules Introduce New Business Obligations
The proposed chemicals legislation is designed to align Montenegro with the EU’s REACH and CLP regulatory frameworks. Companies placing chemicals and products containing chemical substances on the market will face additional obligations related to classification, labelling, safety information, restrictions and supply-chain documentation. Importers will need to ensure compliance and cannot rely solely on foreign manufacturers to meet regulatory requirements.
The impact extends beyond companies directly operating in the chemical sector. Products such as construction materials, detergents, paints, hotel cleaning supplies, fuels and industrial equipment may contain regulated substances. Businesses unable to provide documentation on product composition or classification may face market-access issues even if products have previously been sold without reported problems.
Noise Regulation Could Affect Development Projects
Environmental-noise legislation will introduce requirements related to noise mapping and action planning for urban areas, major roads, airports and industrial sources. The measures could influence operating conditions, construction standards, traffic management and the planning of new developments. For tourism and residential projects, legally defined noise zones could become an important factor in determining the suitability and value of locations.
Marine Protection Strategy Covers Coastal Economy
The Marine Environment Protection Strategy to 2036 establishes an integrated framework for assessing marine conditions, setting environmental objectives, monitoring and implementing measures to achieve or maintain good marine status. The strategy follows the principles of the EU Marine Strategy Framework Directive.
Its implementation will affect activities including wastewater discharges, ports, marinas, dredging, fisheries, shipping, coastal construction and plastic waste management. Tourism facilities may also be affected by wider infrastructure conditions, as individual compliance with permits does not eliminate dependence on municipal systems such as wastewater networks during periods of peak seasonal demand.
Waste Management Requires Major Infrastructure Spending
Waste infrastructure is expected to represent a significant part of the required investment. Montenegro is expected to move from disposal-based systems toward waste prevention, separation, recycling and controlled treatment.
The required infrastructure includes transfer stations, sorting facilities, regional waste-management systems, remediation of non-compliant disposal sites and collection systems capable of serving areas beyond major urban centres. The polluter pays principle will determine how costs are distributed. Municipal projects may initially rely on state funding, European grants or development-bank financing, while users are expected to contribute through water and waste tariffs. Industrial companies will need to finance compliance measures, including permits, monitoring, cleaner technologies and remediation activities.
Industrial Contamination Remediation Remains a Major Liability
Historical pollution sites represent some of the most complex environmental liabilities because previous operators may no longer have the financial capacity to cover remediation costs. The Government has identified remediation related to the former aluminium complex and associated industrial waste areas as examples of major projects. Estimated costs include approximately €32 million for work related to the red-mud pool and around €13 million for a solid-waste landfill.
Protected Areas Influence Future Development
Nature protection requirements introduce additional considerations for spatial planning and investment. Montenegro’s proposed Natura 2000 network covers 44.15% of the country’s total territory, including 50.97% of land areas and 7.06% of marine areas. Protected status does not automatically prevent investment, but projects affecting protected habitats will require stronger documentation, assessment of alternatives and mitigation measures.
Environmental Transition Creates Investment Pipeline
The implementation of Chapter 27 requirements is expected to create demand for engineering companies, environmental laboratories, consultants, construction contractors, equipment suppliers and financial institutions. Projects related to wastewater treatment, water-loss reduction, environmental monitoring systems, remediation and industrial-control technologies represent a multi-year investment programme.
Financing will need to combine national budget resources, municipal funding, private investment, EU pre-accession assistance, the Western Balkans Investment Framework and support from institutions including the EIB and EBRD. Grant financing will be particularly important for projects with significant environmental benefits but limited direct revenue-generation potential.
Coordination and Operating Costs Remain Key Challenges
A major implementation risk is fragmented project preparation and management. Differences in municipal planning standards, unresolved land issues, incomplete permits and insufficient tariff revenues could affect the long-term operation of completed infrastructure. Even projects financed through European support may face difficulties if municipalities cannot cover ongoing costs such as electricity, maintenance and skilled personnel.
The provisional closure of Chapter 27 would mark Montenegro’s acceptance of the EU environmental framework, while implementation of the required €3 billion-plus transformation will depend on long-term planning of projects, institutions, financing sources and operational costs.
