Preliminary new international research has linked the adoption of ISO 14001, the world’s most widely used environmental management systems standard, with significant reductions in GHG emissions intensity.
A two-year research project led by the Standards Council of Canada (SCC) analysed data from 83 countries between 1999 and 2022, identifying a strong, statistically robust correlation between the adoption of ISO 14001 and improved environmental performance.
The study found that a one per cent increase in ISO 14001 certifications is associated with a 0.14% decrease in GHG emissions per unit of GDP, reinforcing the credibility and value of the ISO 14000 family and the relevance of the standard’s new edition, which ISO recently launched.
ISO 14001, the leading International Standard for environmental management, is adopted by more than 670,000 organisations worldwide. ISO 14001:2026, the new edition, updates a trusted framework to align with current environmental priorities, including climate change and biodiversity.
Sergio Mujica, Secretary-General of ISO, said ISO 14001:2026 empowered organisations everywhere to improve environmental performance, cut costs and stay compliant, while building credibility and making a tangible difference for the planet.
“The new edition of ISO 14001 is smoother to implement and integrates seamlessly with other ISO management systems standards, making it easier for organisations of all sizes to embed environmental management into their strategy, achieve tangible results and demonstrate real impact,” Mujica said. “We are encouraged by the findings of this new research and excited to launch the new edition of ISO 14001.”
Chantal Guay, CEO of Standards Council of Canada (SCC), who holds the secretariat for ISO Technical Committee 207 (Environmental Management), said, “We know that standards help reduce costs, improve efficiency, and support stronger economies. We’ve been measuring these impacts at the organisational level.
“But increasingly, through targeted research, we’re able to demonstrate their broader, system-wide benefits. This study is a strong example of that. In simple terms, increasing the use of ISO 14001 is associated with lower emissions, even as the economy continues to grow.
“Another important finding is that countries with more mature standardisation systems—where industry, government, and regulators work closely together—see even greater benefits. These are significant findings that reinforce what we’ve long believed: standardisation delivers real value across economic, environmental, and societal fronts.”
Susan Taylor Martin, Chief Executive of BSI, who holds the secretariat for ISO Technical Committee 207/SC1 (Environmental management systems), added, “Thirty years ago, ISO 14001 redefined how organisations approach environmental responsibility. BSI is proud to have played a leading role in its original creation. Since then, it has provided a shared global framework, enabling hundreds of thousands of organisations to manage their environmental impact in a structured, credible and measurable way.
“As environmental risks become more complex and interconnected, and expectations for transparency and accountability continue to rise, this latest revision represents far more than a routine update. It is a major step forward, strengthening governance, enhancing resilience and aligning with emerging priorities such as climate change, biodiversity and natural capital. It will equip organisations with the tools to embed environmental thinking into strategy, demonstrate real accountability and deliver measurable impact to support the transition to a fair society and a sustainable world.”
While the new research highlights the standard’s impact on GHG emissions, ISO 14001 addresses a broader range of environmental challenges. The standard supports organisations in managing their impact across areas such as biodiversity, resource use, waste and pollution, helping to drive more sustainable practices throughout operations and value chains.
It also provides a robust framework for environmental data collection, management, and reporting, enabling organisations to strengthen the quality and credibility of their sustainability disclosures. By taking a holistic approach to environmental management, ISO 14001 enables organisations to respond to interconnected global challenges and deliver meaningful, measurable improvements beyond climate alone.
By transitioning to ISO 14001:2026, organisations ensure they remain at the forefront of credible, effective and globally recognised environmental management.
The updated standard makes environmental responsibility more accessible for every organisation of all sizes, while also supporting more transparent and consistent reporting aligned with evolving stakeholder and regulatory expectations. In doing so, it helps turn sustainability goals into measurable impact: cleaner air, safer water and a healthier planet for generations to come.
