WHAT IF YOU COULD BREATHE, EAT AND DRINK YOUR FREQUENT FLYER MILES GUILT FREE?

When Justin Brothers, one of the Producers of the Envision Festival in Costa Rica, asked me to write an article about what ACCT does,  I wondered what  I could say that would resonate with this jet setting, fun loving, and mantra murmuring crowd.  Non profit Association Community Carbon Trees- Costa Rica has been working with the ENVISION FESTIVAL since it’s inception 5 years ago in an effort to provide a way for people attending the event to offset their carbon dioxide emitted from the airplanes, trains, and automobiles used to travel to the Southern Zone of Costa Rica. Envision’s example of giving back to the local and global community has set the stage for other festivals to be more environmentally aware not just about their footprint for the festival itself, but also for the planet as a whole due to the countless environmental services and sustainable products rainforest trees so generously give us. Trees do so much for us from sucking up excess carbon dioxide to recycling thousands of gallons of rainwater each year, to providing food, medicine and products. With so many amazing qualities, it is hard to focus on just one reason why we love rainforest trees.

Perhaps one of the most frequently asked questions from people at the festival  is HOW do the trees do their magic? Most people know a little about photosynthesis, that amazing atmospheric chemical exchange occurring in green plants which forms the basis of our symbiotic relationship with them. Humans exhale CO2 constantly, as do land based animals, and many fossil fuel consuming machines and factories. Trees breathe in CO2 and store the carbon molecule while literally recycling our pollution into the oxygen we breathe and the water we drink.

This mutually reciprocal relationship is nothing short of amazing as it provides for our most fundamental needs. Carbon is not the enemy.  In fact, Paul Hawken, esteemed environmentalist, reminds  us that carbon is an  extraordinary element we need to hold hands with and collaborate.   We need to fall in love with carbon.

I say we need to fall in love with rainforest trees too. Because they truly do hold hands with carbon and turn it into food for growth. Nevertheless, tree services often go unnoticed and taken for granted.  That old cliche “Save the Rainforest” never really worked and now we have so much carbon in the air that it has become a menace to society and no one really has invented a better way than a tropical tree near the Equator to absorb it and give us so much back in return.

Let’s go deeper. How do we calculate how much carbon dioxide is captured by any tree? It depends on  the growth characteristics of the tree species, the conditions for growth where the tree is planted, and the density of the tree’s wood.  In other words, how big and hard does the tree grow over time? Where is the tree located and how old is it? Carbon offset  is greatest within 10 degrees of the Equator and in the younger stages of tree growth, between 20 to 50 years.  This is why it is so important for every tree we plant to “keep on living and giving” which makes our long term, paid community farmer rainforest management and conservation program critical to real success.

Do you want to go even deeper?  Of course, all trees planted anywhere are wonderful and generous. But when you start calculating the real carbon sequestration of any given tree, those growing within 10 degrees of the Equator out perform all others because they grow 365 days a year with no real dormant cold season. Here is a basic outline of how the calculation works. First, we determine the total (green) weight of the tree by determining   “W” = Above-ground weight of the tree in pounds, “D” = Diameter of the trunk in inches and H = Height of the tree in feet.  Fn3

Then we determine the dry weight of the tree. This is based on extensive publications with  tables for average weights for one cord of wood for different temperate and tropical tree species. Taking all species in the table into account, the average tree is 72.5% dry matter and 27.5% moisture.Therefore, to determine the dry weight of the tree, multiply the weight of the tree by 72.5%.

Next, we determine  the weight of carbon in the tree.  The average carbon content is generally 50% of the tree’s total volume. Therefore, to determine the weight of carbon in the tree, multiply the dry weight of the tree by 50%.

Determine the weight of carbon dioxide sequestered in the tree. CO2 is composed of one molecule of Carbon and 2 molecules of Oxygen.

The atomic weight of Carbon is 12.001115.

The atomic weight of Oxygen is 15.9994.

The weight of CO2 is C+2*O=43.999915.

The ratio of CO2 to C is 43.999915/12.001115=3.6663.

Therefore, to determine the weight of carbon dioxide sequestered in the tree, multiply the weight of carbon in the tree by 3.6663.6

Finally, determine the weight of CO2 sequestered in the tree per year. To do this, we divide the weight of carbon dioxide sequestered in the tree by the age of the tree.

EXAMPLES

Estimated growth rates and sizes of agroforestry trees were taken from the World Agroforestry Centre’s “Agroforestree Database”:

Let’s see how much a Calliandra calothyrsus ( small leguminous tree native to Central America) might sequester in a year. A 10-year-old Calliandra would probably grow about 15 feet tall with a trunk about 8 inches in diameter. Therefore:

W = 0.25D2H = 0.25(82)(15) = 240 lbs. green weight above ground.

240 lbs. * 120% = 288 lbs. green weight (roots included) 288 lbs. * 72.5% = 208.8 lbs. dry weight
208.8 lbs. * 50% = 104.4 lbs. carbon
104.4 lbs * 3.6663 = 382.8 lbs. CO2 sequestered

382.8 lbs / 10 years = 38.3 lbs. CO2 sequestered per year

If nothing else, it becomes very clear that it is not enough to just plant the tree. Every single tree must be lovingly tended, especially the first four years if it is to grow up over the cattle grasses and form a biodiverse forest canopy to give us maximum environmental benefits.  Each one of these diverse trees contributes over 200 pounds of biomass each year to rebuild soils on deforested cattle farms participating in our programs.  Based on the number of trees Envision has sponsored to date, just picture more than 74,600 pounds of fresh new topsoil added from falling branches, leaves and animal droppings where it used to be just hot mess of cattle grass and erosion! But wait. There’s more! Each tree transpires or recycles  over 200  gallons of  rainwater each year.  By the time the trees reach 20 years old, they have formed a canopy which transpires  over 20,000 gallons of water per acre per year. That is a big deal with the ongoing drought and flood conditions plaguing our planet due to deforestation and unusually higher temperatures year after year.

Local Costa Ricans participating with us, both workers and host farm family members, all paid labor, chop cattle grasses and choking vegetation away from the  base of each and every tree and its perimeter 3 to 4 times per year the first two years, 2 times during the 3rd year and 2 times  the 4th year. This means the majority of the money from each ACCT  sponsorship is going out to the community to make sure each and every tree grows to maturity which is at least 25 years for the carbon sequestration numbers to be real.

ACCT distinguishes itself from most other tree planting groups by allocating money and management to the follow up care of every single tree. We even replace any trees that die the first 4 years. What’s more, we plant a huge diversity of trees. And we do not buy the land either, but rather empower local farmers to work on their own land which means less deforestation.  Through local job creation, ACCT cultivates greater chances of long term rainforest regeneration and conservation.  Social justice has a huge role to play in keeping rainforest standing for future generations.

IMG_0515My,  how we have all grown! As of planting season 2015,  just 5 years after our birth, 16 different family farms are participating in our ACCT forestry programs. Over the past 5 years, Envision Festival has grown as well. They have sponsored 373 trees for Future Generations with a projected measurable carbon offset of at least 373 tons of CO2 over a 25 year period.  We could break down these numbers  to yearly calculations, but given the long term nature of our work and commitment and dedication to forest management, the 25 year cycle is a more fair analysis based on a per tree basis.

So if you are traveling to Envision Festival this coming year 2016, or still want to offset your CO2 from previous years, or even other festivals or events, you can safely calculate that 1 tropical tree will absorb approximately 1 ton of CO2 plus give us all of the other benefits mentioned. We really do hold a powerful, socially just solution in the palm of our hands. And ACCT loves to do the dirty work with our community of men and women! Every single tree does makes a difference.   You have an important role to play. If not you, then who? Envision the forest we are planting. It is real and we need your help!

Smiles All Around for Rainforest Trees!

One of the best things we have done at Community Carbon Trees Costa Rica ( ACCT) is include women in the center of all of our tree production and planting activities. For the past three years, women have been working in our work crews and we can see the positive benefits at all levels of our rainforest tree planting community.

Women can IMG_2336swing machetes, collect seeds, load trucks, carry trees on their shoulders and cut away choking vegetation for good tree growth. They are experts witht he shovel! We watch the women gently care for each and every tree as they plant it and then follow it for 4 years with constant care. The tiny saplings really are babies in need of care out there in the cattle grasses and the women show great success with low death rates and superior growth rates. We could not be more proud of the women who work with our rainforest community.IMG_2349

After a half day of work, (6 am to noon), the women return to their homes and take care of their families with a heightened sense of self esteem and dignity. They share their tree work stories with their families from a positive place. They also feel good about contributing to the family budget. The men in the community love it too. There is a jovial team feeling among everyone involved in our projects. Conversations about reforestation and conservation pepper the dinner table and the whole family gets in on the excitement and the prosperity and dignity that comes from rural families reforesting their own land together. It is hard work but the benefits are obvious to everyone.

Keeping women in the center of our tree planting and care work is a proven recipe for long term success for the whole family.   Great examples are held out for kids and neighbors while we just keep growing more different kinds of trees. There is more good organic food around and people are obviously feeling empowered. No one is going out and illegally cutting down trees. Our participants do not use herbicides or pesticides. There is less desperation in the community of humans and animals and everyone is all smiles all around.
