🌱 Why do sustainability certifications matter in 2026?

Because today’s sustainability professionals need more than awareness. They need credibility, practical skills, and the ability to apply sustainability knowledge across real business operations.

We are proud that the CSE Certified Sustainability Practitioner has been included in Trellis’ “99 Sustainability Certifications for 2026”, under the category “Sustainability and climate professional certifications.”

For 20 years, CSE has supported professionals and organizations in building the expertise needed to turn sustainability knowledge into measurable impact.

“ESG leadership will belong to the companies that can prove performance, not simply communicate ambition.”

This was one of the key messages shared by Nikos Avlonas, Founder and President of CSE, during his participation in the 3rd Annual World ESG & Climate Summit 2026 in Amsterdam.

At a time when ESG claims face increasing scrutiny, credibility matters more than ever. Companies must now show evidence, strengthen assurance, and embed sustainability into products, operations, and decision-making.

CSE remains committed to helping organizations turn sustainability strategy into verified impact.

CSE was proud to participate in the 3rd Annual World ESG & Climate Summit 2026, held in Amsterdam on 27–28 May.

Nikos Avlonas, Founder and President of CSE, joined leading ESG, climate, finance, and sustainability experts to present “Product Circularity as a Strategic Advantage: Ratings and Assurance.”

His session highlighted how companies can move from ESG ambition to measurable performance, credible assurance, and stronger market trust.

As ESG expectations continue to evolve, product circularity is becoming a key driver of transparency, regulatory readiness, and long-term business value.

World Environment Day reminds us that protecting the planet starts with the choices we make every day.

From protecting biodiversity and acting on climate change to choosing circularity and supporting responsible business, every action matters.

Small actions today can help create a more sustainable tomorrow.

Warm congratulations to our valued partners Group of Companies, Ships S.A., Maritime Holdings Corp., and Shipping Inc. for their recognition at the ESG Shipping Awards 2026.

Their awards highlight the growing role of ESG leadership in shaping a more responsible, innovative, and sustainable shipping industry.

At CSE, we are proud to celebrate partners who turn sustainability commitments into meaningful impact.

Sustainability consulting is evolving, and clients now expect practical guidance on ESG regulations, reporting standards, materiality, Scope 3, supply chain sustainability and net zero.
