CDP reporting season is here again. As our sustainability team submits Domtar’s data for this year, let’s look back at last year’s achievements. Domtar’s CDP scores improved in every category in the company’s first disclosure as an integrated company: A− in Forests, B in Climate Change, and B in Water Security. The company also earned an A in the new Commodities (Timber) category.
CDP is an independent nonprofit that scores thousands of companies each year on environmental transparency and performance — which makes these scores something anyone can check for themselves.
What Is CDP and Why Does It Matter?
CDP runs one of the world’s most widely used environmental disclosure systems. Companies answer detailed questionnaires; CDP scores the answers independently and makes the results public. A better score isn’t a marketing claim — it’s an outside assessment of real disclosure and real progress. As Arianne LaBoissonniere, who manages Domtar’s CDP reporting, puts it, CDP is a credible and globally accepted third-party platform for measuring sustainability performance.
What Improved — and From Where
2025 marked Domtar’s first single, integrated submission, and the scores rose across the board.
- Forests improved to A
- Climate Change reached B.
- Water Security scored B
- In CDP’s new Commodities (Timber) category, Domtar earned an A.
That across-the-board improvement reflects two years of work integrating three sustainability programs into one strategy: one set of targets, one measurement system and one public record. The full picture is in our 2025 sustainability report, Advancing Our Sustainability Journey.
What’s Next?
Two commitments are on the calendar. Domtar has committed to setting a science-based greenhouse gas reduction target in 2026, and its first unified Scope 3 emissions inventory will be published in the September 2026 CDP report.
Scope 3 deserves a word of explanation. Greenhouse gas accounting sorts emissions into three buckets: Scope 1 is what a company emits directly, like the fuel burned in its own mills and vehicles. Scope 2 is the emissions behind the energy it buys. Scope 3 is everything else along the value chain — suppliers producing and shipping raw materials, customers using and disposing of products. For most manufacturers it’s the largest share of the footprint and by far the hardest to count, because the data lives in other companies’ operations. Publishing one, unified Scope 3 inventory across three legacy companies is a milestone, not a routine update. Transparency means saying so before the work is finished, not after.
Progress you can verify. We are the fiber for the future.
