The New Carbon Order: IETA Greenhouse Gas Report 2025

IETA’s 2025 Greenhouse Gas Report, The New Carbon Order, brings together some of the world’s leading carbon-market voices, offering authoritative insights across compliance and voluntary markets, government systems, legal frameworks, and the fast-evolving digital frontier. With guest authors from across industry, finance, law, policy, and technology, the report captures both the breadth and depth of expertise shaping this rapidly evolving landscape.

Carbon markets have transcended their status as mere climate policy instruments. They are now the core economic infrastructure for the 21st century – a powerful, dynamic engine capable of solving the challenging equation of decarbonisation without sacrificing economic competitiveness or sustainable growth.

The New Carbon Order is launching at a moment of truth. The question is no longer if markets are needed, but how rapidly we can connect, scale, and integrate the existing patchwork of voluntary and compliance systems into a cohesive, borderless architecture. This is a vital task to ensure capital flows instantly to low-cost abatement opportunities worldwide, while driving innovation across every sector.

This 'System of Systems' is built on core pillars driving future trends and growth opportunities:

  • Competitiveness: Incentives and price signals must be powerful and clear enough to steer the trillions of dollars needed for the climate and transition, ensuring that investment in low-carbon growth is consistently more competitive – appropriate accounting frameworks must encourage and grow global markets.
  • Cooperation: Mechanisms like Article 6 of the Paris Agreement are non-negotiable. They are the essential diplomatic and legal links that allow companies and countries to cooperate on emission reductions, driving cross-border abatement projects and preventing a fractured, protectionist world of isolated and inefficient carbon bubbles.
  • Innovation: Technology is an indispensable catalyst. The Report details how AI-driven verification, digital MRV and blockchain registries are creating a digital backbone that ensures unprecedented transparency, integrity, and operational speed – redefining how capital is deployed in forests, industry, and energy.

The ultimate success of this infrastructure depends on radical collaboration – the meeting point of policy leadership and private-sector innovation. 

  • Governments must set the clear, ambitious frameworks and caps.
  • Businesses must deploy the capital, creativity, and execution at speed.
  • The Global Community must demand credible, fair and equitable outcomes.
