The Trillion Tree Trap: Why Planting Trees Isn’t a Climate Cure-All

Aaron Fisher | August 14, 2025

In the age of viral campaigns and quick fixes, few climate solutions have captured public attention like the trillion tree movement. The idea is simple: plant enough trees, and we can reverse climate change (aka plant trees, save the planet). But as PBS Terra’s investigative video reveals, this popular narrative is not only misleading—it can be environmentally harmful.

20 Years to Carbon Benefits

It takes a forest, and the trees within it, ~20 years for a forest to become a carbon sink. That is until they are 20 years old, a tree emits more CO₂ than it stores.

While young trees grow quick, they also need to breathe in O₂ and breathe out CO_2, just like people, to grow big. And this emissions trend holds until a forest reaches about 20 years old. Furthermore to reach carbon neutrality it takes many more years to offset those emissions in the first 20 years.

So while planting trees will eventually help, it’s way more effective to maintain what we currently have. Especially, because many of our existing trees and forests are already 20 years old.

Survival Rates

As part of the Trillion Tree Campaign, 2000 trees were planted by Mr Beast in Oregon. PBS found the field and sadly only 118 of those trees survived 5 years, a 6% survival rate. What went wrong?

These kind of mass plantations miss out on the complexity and interdependence of nature. Simply put established ecosystems are more resilient. They resist heat, drought, and flooding better than juvenile ecosystems. Which in a world of changing climate have become more frequent, and more stressful to nature.

We need to be more deliberate in ensuring any efforts like this reach the critical threshold. New forests are not set it and forget it.

Harvesting for Lumber

About 50% of an intended harvest is left on site because it is not needed (slash): branches, limbs, leaves, etc. This all decomposes into CO₂ which immediately negates much of the purported benefit.

Lumber harvesting typically occurring around 45 years of age, which means we are finally just approaching carbon neutrality.

It is more impactful to store carbon today than it is at some future date. Environmentalists need to stop greenwashing in the name of the lumber industry.

Clearcutting and Flooding

Another challenge documented by researchers is that clearcutting can make catastrophic floods up to 18 times more frequent, with effects lasting over 40 years. (University of British Columbia study)

Clearcutting reshapes flood patterns, leading to more runoff. These areas saw average flood sizes increase by 50% and peak floods grow by 105% after logging. The study was able to link logging to the 2018 Grand Forks floods, which led to a class action lawsuit against the provincial government and logging companies.

Our bad forestry management worsens climate-related disasters.

Climate Literacy Over Clickbait

The trillion tree campaign may have started with good intentions, but its oversimplification risks undermining real climate progress. Planting trees can and should be part of the answer. Climate solutions must be rooted in science—not slogans.
