We plant the world’s most powerful carbon capturing forests.

Our most productive forest was able to capture a phenomenal 34.21 MT CO2e per hectare per year for the Mohegan Sun Casino.

For decades, Reforest The Tropics has been measuring the productivity of its forest plantations. In June 2017, for the first time, RTT contracted with an accredited third party, EARTH University, to verify its carbon claims under the protocols established by the International Organization of Standards. The results are fantastic news for RTT and anyone with an interest in global sustainability. Verified forests are averaging 23.66 metric tons (MT) of CO2e capture per hectare, per year! To help put this into perspective, most literature on tropical reforestation demonstrates carbon capture of 10-15 MT of CO2e capture under favorable conditions. In other words, RTT is essentially doubling the carbon capacity of current, successful reforestation projects.

One of RTT’s longstanding research goals was to design a mixed-species forest that can capture and store an average of at least 20 MT of CO2e per hectare, per year. Internally, we recognized this target was ambitious, however we have maintained the belief that lofty goals are fundamental to fulfillment of our mission of ‘making a tangible contribution to global sustainability.’ Not only have we met this objective, but we are exceeding it.

The amazing carbon capture of RTT forests is only part of the story however. Two additional pieces distinguish the RTT approach:

  1. RTT’s mixed-species forests are more beneficial to the
    biome than ubiquitous single species monocultures, and
  2. RTT forests are designed to generate perpetual income,
    which allows partnering landowners to participate in the
    project over the long-term.

Essentially, RTT is planting some of the worlds most productive forests…is doing so in more environmentally beneficial manner than typical reforestation models…and is working to ensure they will remain standing indefinitely. Impressive Carbon Capture Verified RTT has focused on forestry research for many years.

Dozens of different planting matrices and mixtures of species have been investigated in order to discover the optimal design to achieve RTT’s three research goals:

  1. Sequester 500 MT CO2e over the initial 25-year
    contract period,
  2. Generate $500 income for the landowner per hectare
    per year, and
  3. Create a ‘permanent’ (read 100+ year) farm forest.

The verification process certified carbon from 8 different designs. The most productive forest was able to capture a phenomenal 34.21 MT CO2e per hectare per year for the Mohegan Sun Casino. Conversely, the least productive design achieved a respectable 11.9 MT CO2e per hectare per year. This design is noteworthy, however because one of the species in this mixture succumbed to a disease and had to be removed. Despite the elimination of hundreds of trees, the 5-year old forest is still productive and will only improve in terms of carbon capture as it matures. This example highlights the importance of RTT’s mixed species orthodoxy and offers a fair warning to advocates of a monoculture approach. Furthermore, if we remove this outlier from our analysis, verification results show that RTT forests are actually storing 25.38 MT CO2e per hectare per year.

The Big Picture: If RTT can plant a forest that doubles or triples CO2 capture of the most common reforestation models per hectare, we only need half the land (or less) to extract a corresponding amount of CO2. We at RTT have long known this is possible and now we have official verification of the RTT model’s potential. We thank you for your support as we spread the word.

We believe in a market based approach to address climate change.

We make it easy for your business to reach it’s sustainability goals while making your carbon-balanced products more attractive to your customer.

RTT believes in a market-based approach to address the issue of climate change. By offering a cost-effective, secure, and efficient approach to long-term carbon emissions balancing, we make it easy for businesses to reach their sustainability goals while making their carbon-balanced products more attractive to the public.

Support a non-profit in a worthy cause


Balance the carbon dioxide emissions of your business!

Reforest The Tropics, Inc. is a local 501(c)(3) non-profit organization that has developed an innovative model to sequester carbon for the long-term by converting cattle pasture to biologically and economically sustainable new farm forests. The program is formally approved by the US and Costa Rican governments and is based on over 50 years of research in tropical forestry. The concept for RTT was approved in 1995 by the United Nations FCCC-AIJ.

How to participate…

Step 1: With the guidance of RTT, calculate the annual emissions of your business.

Step 2: Plan with RTT to offset all, or a portion of, your annual emissions with your donation.

Step 3: Attract new clients and increase sales by communicating your commitment towards sustainable operations.

Step 4: Enhance team morale by touring your forest in Costa Rica!

Your donation will…

Demonstrate your commitment to environmental sustainability.

Provide you with business opportunities by capitalizing on “green marketing” opportunities.

Allow you to stay ahead of the curve in terms of societal and regulatory demands for sustainability.

Be tax deductible.

Support an exciting project that can substantially contribute to the global climate change mitigation effort. Highlights…The RTT program works! The model is a scientific approach to optimize the sequestration of carbon in a new forest, while ensuring sustainability by allowing landowners to profit from prescribed forest thinnings. The program is inexpensive. Many large corporations are already including carbon costs (between $30-60 per metric ton) in their financial projections. The RTT model sequesters a metric ton of carbon for only $15. The approach is necessary. Numerous scientific studies demonstrate that reducing our emissions is not enough. We must actually extract carbon from the atmosphere. New forests are the safest and most cost effective manner for pulling excess CO2 from the atmosphere. Please contact RTT for more details on how the program works for you and the planet!

We make a tangible contribution to global sustainability.

Our model is not simply a “plant a tree” program, rather it is a scientific approach to develop a biologically and economically sustainable ecosystem that can remain as forest perpetually.

One of the research goals of Reforest the Tropics is to develop forests with a 100+ year capacity for CO2 capture and storage. Research began in the 1960s by our staff who tested 99 tree species for farm forests. One of the more interesting species was Araucaria hunsteinii, or the “Klinkii Pine” from Papua New Guinea. This species has proven to be an ideal candidate for inclusion in mixed-species plantations. It is noninvasive, grows to tremendous sizes, produces high quality timber, shows promise as a shade tolerant species that can be planted beneath existing canopies, and it coexists well with other species in RTT mixtures. The tallest Klinkii ever formally measured was 273 feet in height and over 6 feet in diameter. This gives the tree a special potential, namely of being able to store CO2 in the form of wood in a live forest stand for a very long time.
Klinkii is now included in virtually all of RTT’s mixed-species designs. RTT’s approach is to develop and test mixed-species models, which reduce the risks of disease and pest attacks associated with traditional monocultures. They also enhance biodiversity, create habitat for a variety of fauna, and have been shown to be more productive than monocultures in their ability to fix CO2.
