Turkey Sustainability & Tax Guide 2026 – Pre-COP31 Edition

A Comprehensive Framework for Foreign Sustainability, ClimateTech, Energy Transition and ESG-Driven Companies Entering the Turkish Market Ahead of COP31

Introduction

Turkey’s selection as the host country for the United Nations Climate Change Conference (COP31) in November 2026 has accelerated the nation’s transition toward a low-carbon economic model. Over the next 24 months, Turkey is expected to implement substantial regulatory, fiscal, and institutional reforms. These measures are designed to align with international climate expectations, attract green investment, and position the country as a regional sustainability hub bridging Europe, Asia, and the Middle East.

For foreign businesses operating in renewable energy, environmental technologies, ESG reporting, green finance, carbon markets, or sustainable manufacturing, Turkey’s evolving landscape offers significant opportunity—provided companies understand the country’s tax structure, incentives, compliance obligations, and practical market-entry considerations.

This 4,000-word Pre-COP31 Edition consolidates the full spectrum of regulatory, tax, investment, and sustainability-related topics relevant for foreign enterprises planning operations in Turkey during the crucial 2025–2030 window. The aim is to offer an authoritative guide for investors requiring clarity, precision, and strategic foresight.

1. Turkey’s Green Transition Framework in 2026

Turkey’s climate and environmental policies have gained unprecedented momentum following its ratification of the Paris Agreement in 2021 and reinforced by its commitment to host COP31.
