ANTALYA, Türkiye — Türkiye and the Asian Infrastructure Investment Bank (AIIB) have agreed a record $1.6 billion climate-focused financing package to help the country implement emissions reforms, expand sustainable finance and strengthen its defences against climate risks, the bank announced on Thursday at the COP31 United Nations climate conference in Antalya.

The agreement is AIIB’s largest climate policy-based financing package to date. It is designed to support Türkiye’s Climate Law and its updated national climate commitments, including an interim emissions target for 2035 and the country’s ambition to reach net-zero emissions by 2053.

The deal comes as Türkiye faces a major funding challenge. AIIB estimates that the country will need an additional $68 billion in climate investment by 2030, with around half expected to come from private sources. The new package is intended not only to provide financing but also to strengthen the policy and regulatory conditions needed to attract further investment.

What The $1.6 Billion Package Will Fund

According to AIIB, the programme combines two equal financing components: a Climate-Focused Policy-Based Financing loan for the Türkiye Climate Action Acceleration Program and supplemental financing under the bank’s Energy, Food Security and Economic Resilience Facility. Together, they total $1.6 billion.

The programme is organised around three main pillars: sustainable finance, sectoral decarbonisation and climate resilience. These pillars are intended to connect national climate targets with government policy, financial regulation and practical changes across the economy.

Emissions Trading And Green Finance

A significant part of the reforms will support Türkiye’s emerging emissions trading system. Under such a system, companies in covered high-emitting industries receive or acquire emissions allowances and can trade them, creating a financial incentive to reduce pollution.

The programme aims to have at least 180 facilities report baseline emissions under the system by April 2027. It also seeks to strengthen the country’s green finance framework and expand the use of financial instruments that direct capital towards lower-carbon projects.

The reforms could also matter for Turkish exporters, particularly producers of steel and cement that sell into the European Union. A domestic carbon-pricing system may help companies account for carbon costs already paid in Türkiye under the EU’s carbon border rules, although the commercial benefit will depend on how the Turkish system is designed and recognised.

Renewable Energy Capacity Gets A Boost

The financing programme includes a target to secure production licences for 1,800 megawatts of wind and solar capacity by early 2027. The objective is to accelerate the development of renewable electricity and support the country’s broader emissions-reduction plans.

Expanding renewable power can help reduce dependence on fossil fuels, diversify energy supply and limit exposure to volatile international fuel prices. However, licences are an early stage in project development: actual delivery will also depend on financing, grid connections, construction, permitting and the ability to integrate variable renewable power into the electricity system.

Farmers And Water-Stressed Regions Included

The programme also recognises that climate policy must extend beyond energy and heavy industry. AIIB says the plan aims to help 225,000 farmers in water-stressed basins switch to crops that require less water by 2028.

Another target is to designate 50,000 hectares of land as carbon sinks by 2028. Carbon sinks are natural or managed areas, such as forests and certain soils, that absorb and store carbon dioxide from the atmosphere.

These measures are particularly relevant as Türkiye faces increasing pressure from water scarcity, drought, extreme heat, wildfires and urban flooding. Better water management and more climate-resilient agricultural practices could reduce risks to rural livelihoods and food production, although implementation will require sustained technical support and local participation.

Why The Deal Matters At COP31

COP31 is taking place in Antalya from November 9 to 20, with Türkiye hosting the conference and Australia leading the negotiations. The summit is focused heavily on implementation: translating existing climate promises into policies, projects and measurable results.

The AIIB agreement gives the host country a major financing announcement at a summit where climate finance remains one of the most difficult issues. Developing countries have repeatedly argued that ambitious emissions and adaptation targets cannot be achieved without predictable, affordable funding and stronger support from international financial institutions.

For Türkiye, the package is also a way to demonstrate how climate goals can be built into fiscal policy, financial regulation and planning across all 81 provinces. AIIB says the programme is led by the Turkish government, with the Ministry of Treasury and Finance coordinating implementation alongside the Ministry of Environment, Urbanisation and Climate Change and other public agencies.

A Record Loan Is Not The Same As Climate Results

Although the $1.6 billion agreement is a major financing commitment, its success will ultimately be measured by what changes on the ground. The programme’s targets provide milestones, but progress will depend on whether emissions trading becomes operational, renewable energy projects reach construction and production, farmers receive practical support, and climate risks are incorporated into public planning.

The financing is also only part of the much larger investment requirement identified by AIIB. With Türkiye seeking another $68 billion in climate investment by 2030, mobilising private capital will be essential. That will require credible regulations, transparent project pipelines, stable incentives and confidence that climate policies will be implemented consistently.

The package therefore represents both an immediate financial commitment and a test of whether policy-based lending can unlock broader investment. If the reforms are delivered, they could support cleaner energy, more resilient agriculture and better preparation for extreme weather. If implementation falls short, the headline financing figure alone will not deliver the country’s climate ambitions.
