Green Finance and Sustainable Investment Instruments in Türkiye
In 2025, Türkiye has firmly positioned green finance and sustainable investment at the core of its economic transformation agenda. The country’s government institutions, financial organizations, and private sector are collaborating to achieve a balance between environmental sustainability and economic growth. This alignment aims to build a resilient financial ecosystem capable of supporting long-term climate goals.
Regulatory Framework and Strategic Policies
National Climate Policy and Emission Targets
Türkiye’s climate policy landscape has reached a pivotal stage. The Ministry of Environment, Urbanization, and Climate Change published the 2025 Performance Program on January 31, 2025, raising the national greenhouse gas (GHG) reduction target to 41%. This enhancement aligns Türkiye with the Paris Agreement and the European Green Deal. The nation’s long-term goal remains achieving Net Zero Emissions by 2053.
Under the 2024–2030 Climate Change Mitigation Strategy and Action Plan, Türkiye identified seven primary mitigation sectors: energy, industry, buildings, transportation, agriculture, waste, and land use, land-use change, and forestry. Within these areas, 49 strategies and 260 actions are defined to ensure an integrated and measurable transition.
National Green Taxonomy
To strengthen the green finance ecosystem, Türkiye is establishing a National Green Taxonomy compatible with international standards. This system will provide clear definitions of environmentally sustainable projects, guiding financial flows toward sectors with measurable climate impact.
Green Finance Instruments
Green Bonds
Türkiye’s green bond market began in 2017 with the issuance of the first local green bond by the Industrial Development Bank of Turkey (TSKB). The market remains in a developmental phase, with primary funding directed toward renewable energy and energy efficiency projects.
The Capital Markets Board of Türkiye (SPK) introduced its Sustainability Reporting Communiqué in 2020, encouraging companies to disclose Environmental, Social, and Governance (ESG) performance. These reporting requirements have improved transparency and fueled investor confidence, paving the way for standardization in green bond issuances.
Financing Mechanisms and Grant Programs
Türkiye’s green finance models have expanded to include a wide range of incentives and concessional credit. Through the Türkiye Green Finance Project, supported by the Ministry of Treasury and Finance and the World Bank, TSKB secured a 155 million USD loan to fund corporate green transformation. These mechanisms target low-carbon investments and encourage the private sector to adopt sustainable practices.
Institutional Leadership and Support Structures
TSKB’s Leadership in Sustainable Finance
TSKB remains the key institution in the country’s ESG and green finance initiatives. The bank continues to expand its venture capital portfolios through Maxis Private Equity Portfolio Management Inc., enabling new sustainable investments across multiple sectors. Its focus lies on energy transition, low-carbon industry, and digital sustainability solutions.
Regulatory and Supervisory Bodies
Türkiye’s financial regulators play proactive roles in sustainability:
- BDDK: provides strategic guidance for banks to integrate ESG and sustainable lending policies.
- Central Bank of the Republic of Türkiye (TCMB): supports green financial instruments through monetary and prudential frameworks.
- TÜRKÇEV: facilitates environmental project financing, consultancy, and awareness-building.
Sectoral Transformation Strategies
Renewable Energy
Under the 2024–2028 National Transformation Investment Strategy, renewable energy is identified as a key priority. Türkiye is streamlining administrative procedures, reducing investment costs, and providing targeted incentives to encourage private sector participation in solar, wind, and geothermal projects.
Circular Economy and Industrial Decarbonization
Industrial policy integrates resource efficiency and circular economy models to reduce sectoral carbon intensity. Policies promote low-emission production technologies and digital integration across manufacturing supply chains, advancing Türkiye’s competitiveness in sustainable industry.
Built Environment and Transportation
The construction sector targets the adoption of nearly zero-energy buildings, while district heating and cooling networks are being expanded. In transportation, electrification and the transition to low-emission mobility systems are being accelerated, reducing urban air pollution and energy dependency.
International Alignment and Competitive Positioning
EU Green Deal and Carbon Mechanisms
Türkiye is advancing its climate policy alignment with the European Union through the implementation of carbon pricing mechanisms and the introduction of an Emissions Trading System (ETS). This harmonization supports exporters in maintaining market access to the EU and strengthens Türkiye’s position as a competitive regional hub for sustainable production.
Investor Appeal
The synergy between policy, technology, and financial innovation has made Türkiye increasingly attractive to international investors. The stabilization of interest rates in late 2025, combined with ongoing merger and acquisition activity, has led to greater engagement in sustainable finance and green venture markets.
Financing Access and SME Support
Small and medium-sized enterprises (SMEs) form a critical part of the green transition. Through KOSGEB, the government has allocated 250 million USD to support energy efficiency, circular economy, and emission reduction projects. Updated Treasury guidance documents provide detailed information on financial instruments available for achieving the green transformation objectives.
Market Potential and Growth Outlook
Although Türkiye’s green bond and finance markets remain in the early stages compared to developed economies, the growth trajectory is positive. Increasing investor awareness, expanding renewable investments, and government support form a solid foundation for market maturation.
Future development will depend on three main factors:
- enhancing regulatory infrastructure and standardization;
- improving transparency and impact reporting mechanisms;
- strengthening verification and sustainability consulting capacities.
This ongoing evolution positions Türkiye as a leading regional player in sustainable finance and a dynamic destination for investors focused on ESG-driven growth.
