"Integrity and impartiality are the priority": How McGill St. Laurent backs up its carbon trading desk with third-party trust

July 22, 2026 - Customer Stories

McGill St. Laurent is a commodity trading firm based in Montreal, Canada. As the firm expands its operations beyond Quebec and works with large corporate clients, the dynamics of its carbon portfolio are evolving.

We spoke with Pierre-Luc Lamontagne, Carbon Solutions Lead at McGill St. Laurent, about how the firm works with Calyx Global to validate complex projects, manage client expectations, and uphold the highest standards of market integrity.

Meeting the market for third-party trust

As the voluntary carbon market matures, buyers value quality and transparency. For McGill St. Laurent’s expanding client base, independent validation has become a critical part of that.

"Bigger clients want to have either the project or the methodology rated by a third-party agency," Pierre-Luc explains.

This rising demand drives corporate buyers to require unbiased, independent verification for both specific project outcomes and underlying methodologies before making large-scale commitments. To meet this need and confidently guide their clients, McGill St. Laurent works with Calyx Global to do diligence on credit quality.

How Calyx Global helped

As McGill St. Laurent expands its carbon trading desk, the company is evaluating projects in a growing number of geographies and with new methodologies. Calyx supports them with a dedicated team of subject matter experts to complement McGill’s expertise.

"Calyx handles a huge variety of project types, from every standard and a lot of countries. The team really understood the specific project and methodology we asked them to analyze, and has a large number of people who can speak to unique questions and needs.”

Prioritizing integrity over expectations

In the carbon market, reality doesn’t always align with initial commercial hopes—but that is exactly where the true value of independent ratings lies.

"Integrity and impartiality are always the priority for us and for Calyx," Pierre-Luc notes. "Credits might get a higher or lower rating than we expect, but Calyx always backs up its analysis with strong arguments."

McGill St. Laurent and Calyx are both committed to sharing honest views of the risks and opportunities of different credits, meaning ultimate buyers can invest with greater confidence.
