The Most Regulated Fiber Is the MostSustainable — And the Least Regulated Is the Most Harmful

We need to talk honestly about cellulose, polyester, and the future of textile materials

Throughout my 37-year career in the cellulosic fiber industry, one narrative has persisted in sustainability circles: “Cellulose = deforestation.” Meanwhile, the harmful aspects of polyester are largely ignored.

Here’s the reality most people don’t see:

• Over 90% of dissolving pulp for MMCFs comes from certified, responsibly managed forests.

• These forests are regrown, stewarded, and independently audited — they are carbon sinks, not carbon sources.

• The cellulose industry is one of the few that requires long-term replanting and must comply with an ever-expanding landscape of regulations each year.

Meanwhile:

• Polyester fibers are fossil-derived, non-biodegradable, and responsible for 35% of ocean microplastic pollution.

• The polyester industry remains almost entirely unregulated, largely untraceable, and rarely scrutinized by NGOs.

So why does cellulose face intense scrutiny while polyester gets a free pass?

Because cutting trees feels emotional. Extracting fossil fuels feels distant. Regulation follows emotion, not science.

Close: If we want real sustainability progress, we must stop punishing renewable materials and start addressing the fossil-based ones.

This is why I’m launching Expand the Forest — a positive, science-driven effort to champion responsible cellulose and the managed forests that support it.

It’s time to rebalance the conversation.
