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:
- RTT’s mixed-species forests are more beneficial to the
biome than ubiquitous single species monocultures, and
- 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:
- Sequester 500 MT CO2e over the initial 25-year
- Generate $500 income for the landowner per hectare
per year, and
- 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.
