Moving Past the Fear of Impermanence

How science-based strategies help manage durability risk in carbon-crediting Natural Climate Solutions

By Susan Cook-Patton, Lead Reforestation Scientist, & Campbell Moore, Managing Director, Carbon Markets

A hundred years ago, humans traveled around the world via airplane for the very first time. Getting there took 175 days and four planes. Contrast this feat of daring and endurance with today: A round-the-world flight only takes hours.

We cannot know exactly what the world will look like in 100 years. Yet we have not let this uncertainty inhibit bold action, action that has resulted in progress. And we can’t let it stop us from investing in nature as a climate solution today.

We can’t let uncertainty stop us from investing in nature as a climate solution today.

Reducing fossil fuel emissions remains paramount in humanity’s journey to a livable future. But we must also work with nature to avoid the worst of climate change. This means protecting, better managing and restoring forests, grasslands, wetlands and agricultural lands around the world—rapidly and at scale. But these solutions only arrive through investment, and carbon markets represent an essential financing mechanism.

Carbon projects should set a high scientific bar for calculating long-term benefit for the climate. One facet under intense scrutiny is whether a forest can store carbon for 100 years. While guaranteeing 100 years of durability may seem daunting, science can help us navigate this complexity. The alternative is ignoring a three-billion-year-old technology called “photosynthesis” that uses sunlight to easily move carbon dioxide from the atmosphere into land-based carbon storage.

The alternative is ignoring a three-billion-year-old technology called ‘photosynthesis’ that easily moves carbon dioxide from the atmosphere into land-based carbon storage.

Instead of fearing that disaster will strike everywhere, let’s leverage the best-available science to focus investments on places and strategies that are more likely to remain stable. As the science improves, we can increasingly tip the odds in our favor. Here’s how:

1. Reduce the risk of carbon loss.

As the climate crisis worsens, forests should be protected, managed and restored in places where the chance of losing large amounts of carbon is low and where carbon can be recovered quickly if a natural disaster occurs. Our latest science gives unprecedented clarity on where best to restore forest cover for climate. There are even places where increased carbon storage is expected with climate change—as CO2 fertilization and warming temperatures can both boost growth.

From Crisis to Renewal

The Power of Investing in Nature

Even when natural disaster does strike, the carbon that is released is not lost forever. Natural systems regrow. A forest may burn down, but from the ashes a new forest can rise. A hurricane may blow down scores of trees, but the remaining trees will rapidly expand to fill the gaps. Nature is the original comeback kid.

With TNC-led science we are getting better and better at predicting how much and how quickly carbon will be be recovered after disturbance. And we can design interventions with resilience in mind—for example, by planting fire-adapted species or increasing prescribed burning to set up more natural fire regimes.

2. Use risk management mechanisms to compensate.

Risk is and has been part of every aspect of life on earth. From crop and flood insurance to retirement investment accounts and long-term financial instruments like trusts, there are well-established risk control systems that allow us to handle uncertainty.

For carbon markets, simple insurance mechanisms called “buffers” already exist. They can help control the risk of losing carbon in natural disasters for some years to decades, while we develop better solutions. For example, the buffer system used by Verra, which certifies most of the voluntary carbon market, has more than 70 million credits on hand to compensate for reversals yet so far has only been called on a handful of times. These buffer systems are not perfect, and their improvement needs to be informed by better science. Fortunately, scientists are already working on it.

3. Strengthen nature to do what it does best.

The musts of NCS

What are real, high-integrity natural climate solutions?
These principles provide guidance on what constitutes a natural climate solution so that investments can be made with confidence. Learn why NCS must be nature-based, sustainable, climate-additional, measurable and equitable.

Approximately half of the carbon from fossil fuel burning is pulled back into the land and ocean—we are already reliant on nature to protect us from climate change and to prevent crossing irreversible tipping points in the planetary system. Carbon markets, and the natural climate solutions they finance, are simply a strategy to enhance and optimize that irreplaceable natural benefit we already rely upon.

Acting now by strengthening nature gives us valuable time to address hard-to-abate sectors, form coalitions necessary to unlock political change and continue developing other solutions.

 

4. Follow the lead of local communities.

Local communities are at the forefront of generational leadership. Our rule of thumb at TNC is that an NCS project must make people’s lives better. If we want the carbon stored in a forest, grassland or farmland to be there decades from now, it is critical that the intervention storing that carbon is co-designed with farmers, landowners and communities to make their lives better as a result.

This is the case of the DeSeves, one of more than 1,000 families who have signed on to the Family Forest Carbon Program. They joined the program to give their land a new purpose—one that supports climate goals while staying rooted in family values. Managing their forest for carbon storage has become a shared commitment, connecting generations through practical stewardship.

Right now, we are in a climate emergency. We should start acting like it. Climate change causes increasingly more damage with every fractional increase in warming. Nature offers ways to address carbon emissions, using methods that have been on Earth for eons. But what if the worst comes to pass? Let’s say by 2100 climate impacts are so severe that we lose a lot of the carbon we stored through the efforts above. Even in this worst-case scenario, we will have delayed peak warming, given ourselves time to develop other complementary solutions, invested hundreds of billions in sustainable economies around the world, made lives better for tens of millions of people, saved species from extinction and created a greener (yet still damaged) planet.

So let’s be bold. And let’s be smart about it. Let’s use essential solutions at our disposal today, like NCS and carbon markets, and commit to improving them in the decades that come. It’s really that simple.
