Why Carbon Credits Are The Next Opportunity For Farmers - YouTube

This is a good friend of mine's field. And he's doing the same
[4]
thing I'm doing, growing corn, right, for harvest. He's just
[7]
doing it a lot differently. You've got the contrast of the
[10]
the soil versus the corn. You've got the beautiful rows straight
[14]
down. This is what I envisioned when I was a kid, of doing when
[18]
I was older is farming just like this. And when you get into
[22]
regenerative ag, you've got chaos.
[24]
On Trey Hill's farm in Maryland, the fields look a lot different
[27]
than the clean, orderly rows of crops that his friend is
[29]
growing. Unlike his friend, who tills his fields after fall
[33]
harvest and leaves them barren for the winter, Hill plants rye,
[36]
turnips, clover and a few other species of plants in the off
[39]
season so that his fields stay covered year-round. Known as
[43]
'cover cropping,' this practice is just one piece of a movement
[46]
called 'regenerative farming.' The approach focuses on
[49]
replenishing the soils nutrients and also includes things like
[51]
no-till cultivation, rotational cattle grazing and using less
[55]
synthetic fertilizers.
[56]
What we do is, after we harvest our corn or soybeans in the
[59]
fall, we plant a subsequent crop called a cover crop.
[62]
And that's what we're standing in right now. But then, when we
[64]
go to plant corn, our planters will go right directly through
[68]
this and put the seeds in the ground in the middle of all of
[72]
these flowers, and then we'll spray the cover crop off, and
[76]
it'll die and decompose into the ground and the corn will come up
[80]
through it.
[80]
As the cover crops grow, and eventually decompose, they
[83]
provide nutrients for microbes and improve the soil's health.
[86]
At the same time, the plants pull CO2 out of the atmosphere
[89]
and store in the soil.
[90]
Globally, about 25% of our climate change pollution is
[94]
caused by food and agriculture. Most of that's because we're
[97]
deforesting places like the Amazon to create more farmland.
[101]
But also the methane that comes out of our cattle and rice
[105]
fields is also contributing to climate change, as is the over
[108]
use of fertilizers and other things. But regenerative
[111]
agriculture seeks to reverse that, and not only, kind of, cut
[115]
down the pollution, but maybe in some cases even soak up some of
[119]
the pollution we put in the atmosphere, particularly carbon
[122]
dioxide.
[123]
Driven by climate conscious consumers, a number of massive
[126]
corporations, including General Mills and PepsiCo are vowing to
[129]
scale regenerative practices across millions of acres of
[131]
farmland. But can it help tackle climate change?
[144]
For the last five years, Hill's planted year-round cover crops
[147]
and refrained from tilling the soil, which prevents the trapped
[149]
carbon that he's worked hard to sequester, from escaping back
[152]
into the atmosphere. He says his yields are comparable to what he
[155]
would have gotten through conventional farming, but since
[158]
starting to farm regeneratively, he's noticed that his soil is a
[160]
lot healthier and his crops a lot more resistant to pests and
[163]
extreme weather such as floods and droughts. He's also seeing
[166]
some savings.
[167]
In terms of the regenerative, it's a lot more work in the fall
[169]
because you're adding a another planting season. But in the
[172]
spring, it's a lot less work. In the spring, we used to run a
[175]
disk, a plow, and then the land finisher and then the planters.
[179]
Now we run the planter and that's it. It's offset a lot of
[182]
our diesel costs, it's offset a lot of tractor costs, it's
[184]
offset a lot of tillage costs, all that stuff is expensive. So
[188]
it actually is a much more efficient way to farm. It just
[191]
there's it adds a lot of complexity.
[194]
Initially HIll begin forming regeneratively to appease local
[197]
environmental groups, who were worried about runoff from farms
[199]
polluting the Chesapeake Bay. Plus, Maryland has one of the
[202]
most robust cover crop incentive programs in the country.
[205]
Right now, we get between I think it's roughly $45 or $50 an
[209]
acre to do cover crops.
[210]
But Hill is also generating revenue from selling credits
[213]
through Nori, a small carbon marketplace based in Seattle.
[216]
Lately, there's been an explosion of private
[218]
marketplaces like Nori and Indigo Ag. Here, companies and
[222]
individuals eager to offset their own footprints can
[224]
purchase carbon credits from farmers who've sequestered CO2.
[228]
But some are skeptical that companies will use the markets
[231]
as an excuse to continue business as usual. Still,
[234]
McKinsey estimates that the market for carbon credits could
[236]
be worth over $50 billion in 2030. The Biden administration
[240]
has also earmarked $30 billion to help pay farmers to implement
[244]
sustainable practices and capture carbon in their soil.
[247]
Part of these funds could be used to create a federal carbon
[249]
bank, which would stabilize the price of carbon.
[252]
Okay, 10-4 well we can go ahead and do it then.
[255]
Last year, HIll became the first farmer in the country to sell
[257]
carbon credits through Nori. Currently, Nori offers its
[260]
farmers $15 for every metric ton of CO2 they sequester,
[264]
We put in all of our data for the farm, our yields were,
[267]
planting dates, what our cover crops are, what our cover crop
[270]
plant dates are, when our cover crop was killed, all of these
[273]
different things and we put it into a model that was developed
[275]
by the Department of Agriculture. What it ended up
[277]
being is about a ton of carbon per year per acre.
[281]
Hill says his farm already keeps records of most of the data
[284]
required by the carbon sequestration model, which made
[286]
the process easier, but not every farm does. And keeping
[290]
track of all this data can eat up valuable time.
[293]
We didn't do every field, it's a lot of work to get the model
[295]
done. So we took a portion of what we farm and sold that into
[299]
the carbon markets.
[300]
After paying a third-party auditor $4,000 to verify
[303]
Harborview's data, Hill has so far made around $210,000 for
[307]
sequestering just over 14,000 metric tons of carbon over the
[310]
course of five years.
[314]
So that's compost. And it's basically turning into really
[319]
awesome soil.
[320]
Loren Poncia owns Stemple Creek Ranch in Northern California.
[324]
Through a partnership with the Marin Carbon Project, a
[326]
consortium of independent agricultural institutions,
[329]
Poncia has also adopted a number of regenerative farming
[331]
practices. These include applying compost instead of
[334]
chemical fertilizers to pastures to avoid tilling, and
[338]
periodically moving livestock from one pasture to another,
[341]
thus giving the grass and soil a chance to recover.
[343]
We're part of this study, a 10-year study, that had a
[347]
35-acre treatment plot. And basically what we're seeing is
[351]
we sequester about 3,000 to 5,000 pounds of carbon per acre
[355]
per year. Poncia has already received state funding from
[358]
California's Healthy Soils Program to implement sustainable
[361]
farming practices on his ranch, but says he's not yet ready to
[364]
sell carbon credits on the private market because of the
[366]
high cost of determining how much carbon is contained in his
[368]
soil.
[369]
The carbon that we're putting in the soil has allowed us to grow
[372]
so much more forage that we are making more money now and
[375]
selling more pounds of protein now than we did 10 years ago.
[379]
But we haven't gotten to the point where we're selling carbon
[383]
credits to the open market, mostly because the value of the
[386]
carbon credits isn't really worth going through all of the
[389]
process of monitoring and measuring in order to pay for
[392]
them.
[393]
Current carbon market for pasture-based carbon
[396]
sequestration is somewhere between $5 and $10 per carbon
[400]
credit. And in order for me to get interested, I would be you
[404]
know, more like $80 or $100 a carbon credit.
[409]
Hill and Poncia agree that regenerative farming has been
[411]
beneficial for soil health and their businesses. But the jury
[415]
is still out on how effective the practices are when it comes
[418]
to mitigating climate change. For one, setting up a carbon
[421]
market is tricky, because measuring carbon sequestration
[424]
is hard.
[425]
Back in the 1990s, there was something called the Chicago
[427]
Climate Exchange, which was trying to trade carbon credits
[430]
from farmers with companies who were, very early on, talking
[433]
about greenhouse gas pollution. And the idea was, back then we
[436]
thought farmers who didn't till their landscape, didn't plow it
[440]
up every fall, would be absorbing carbon. They do, in
[443]
the top few inches of the soil. But then, when we started
[447]
measuring the lower parts of the soil, we noticed that they
[449]
weren't accumulating carbon as much. And it kind of became a
[452]
wash. And then, the whole idea of that market kind of fell
[455]
apart.
[456]
Even today, figuring out how much carbon is trapped in the
[458]
soil is not an exact science,
[461]
The traditional method is you take a core, you stick a big
[464]
kind of pole in the ground and pull up like what's basically a
[468]
long rod filled with soil. And you take that out and you
[472]
actually stick it in a really hot oven ,essentially, and you
[475]
bake out the water. But then eventually you bake out all the
[478]
organic matter, you burn it all off and measure the CO2 that
[481]
comes out. That's really time consuming, expensive. And you
[485]
basically get a measurement for the place you stuck the pole in
[487]
the ground. So you have to then go do that again and again and
[491]
again across the farm. Because every little patch of land is a
[494]
little bit different.
[495]
The other option is to use an algorithm.
[497]
Sometimes, what we do is we rely on an algorithm that says, well
[500]
based on the topography, the basic soil chemistry where you
[505]
are, the climate where you are, and the way you're farming, I'm
[508]
going to go look at 100 other farms who did something similar
[511]
and give you like a ballpark number to use as kind of a
[515]
baseline to credit the carbon that you're putting away.
[519]
Assuming that you get an accurate number for how much CO2
[521]
has been stored, the next challenge is ensuring that the
[524]
CO2 will remain in the soil long term.
[526]
In America, a lot of farmland isn't owned. It's leased by the
[530]
farmers. And so there's turnover. So I think as a
[533]
policymaker, members of Congress, the Biden
[535]
administration and so on, if they're going to plan to kind of
[538]
pay farmers to do this, or if companies paid farmers to do
[541]
this in some kind of market, how are you paying them to ensure
[544]
it'll be there for the next 100 years?
[546]
Nori demands that sellers on its marketplace sign a 10-year
[549]
contract promising that they will continue farming
[551]
regeneratively.
[552]
So in Nori's market, the farmers are signing a 10-year contract
[556]
with us that says that they're obligated to keep that carbon in
[560]
the ground and they have to re-verify the data that that
[563]
we're using for quantification, at least every three years. And
[566]
then at every three year verification mark, they can sign
[570]
a new 10-year contract.
[571]
Such a long commitment can be tough for farmers.
[574]
As a farmer, that's a huge risk. If we get a hurricane in the
[577]
fall, say September, and I have to harvest after 22 inches of
[581]
rain, I'm probably gonna have to do some tillage. At least in
[584]
places. What if I don't own the land? The owners that I rent
[587]
from, t's not typical to get a 10-year agreement because as the
[590]
markets fluctuate, so do the rental prices. I have some
[593]
owners that don't like this look. It's their farms and
[596]
they'd like it to look neat and clean and this is definitely a
[600]
different look than a freshly plowed field.
[602]
And Hill's not alone. According to the latest numbers from the
[605]
USDA, around 40% of the farmland in the US was rented in 2014.
[610]
Hill says challenges like these are why he's only sold about 35%
[613]
of his fields into the carbon market.
[615]
The biggest cost, of course, is time. If farmers have to switch
[619]
the way they're doing things from what they used to do for
[621]
years, which reliably could give them productivity and income,
[625]
and have to make some adjustments. During that time,
[628]
you might not be earning very much. Or maybe it takes time for
[631]
the farm, the ranch to shift to getting into kind of settling
[635]
into these new practices. So that's probably why it'd be good
[638]
to see things like price supports and government
[640]
assistance for these kinds of agriculture.
[645]
Coming up with accurate measures of carbon sequestration and
[647]
figuring out how to keep that CO2 in the soil long term are
[650]
moot points, unless farmers agree to adopt regenerative
[653]
practices in the first place. Nori currently only has six
[657]
farmers who are fully enrolled onto its marketplace and Foley
[660]
estimates that regenerative farming is still only practiced
[662]
on less than 1% of the farmland in the US. In order to gain
[666]
wider adoption, Hill and Poncia think there needs to be more
[669]
incentives for farmers.
[671]
I think what we need to do is be able to couple markets together.
[674]
So you know, if we can sell the $15 credit on the carbon market,
[678]
you know, maybe we can save another few dollars on crop
[680]
insurance. We're offsetting risk by growing crops this way. So it
[683]
should save crop insurance money anyway.
[686]
If the government would subsidize carbon in the soil
[690]
instead of subsidizing mono crops across the country that we
[695]
end up exporting overseas anyway, I think we could
[698]
definitely gain a lot of ground very quickly. If we could make a
[703]
living selling the carbon, I would love it.
[706]
As for a federal carbon market, Hill says that may not be a good
[709]
idea.
[710]
We have to turn over so much data in order to make this
[713]
marketplace valid, transparent and true. I don't know how many
[717]
farmers are going to be comfortable turning over that
[719]
level of information to the Farm Service Agency.
[722]
Most experts agree that regenerative farming is
[724]
beneficial and should be encouraged. But they say that
[727]
it's by no means a silver bullet for solving climate change and
[730]
should not be used as an excuse to continue emitting greenhouse
[733]
gases in other places
[734]
If we're paying farmers to secure carbon from the
[737]
atmosphere as an excuse not to turn off the dirty power plant
[741]
or to stop some industrial process somewhere else, that's
[744]
not a good idea.
[745]
Foley thinks we should also temper expectations of just how
[748]
much carbon farmers may be able to sequester.
[751]
There's always going to be a certain limit of land or how
[753]
much the soils can absorb or how fast they can absorb it. You
[757]
could put a sizable amount of carbon, maybe the equivalent of
[759]
a few years of our emissions back into the world soils, if we
[763]
did a massive regenitive push around the world. And that's
[766]
nothing to sneeze at. But again, it's not a silver bullet to
[768]
climate change. But the nice thing about regenerative
[770]
agriculture, despite the limits of it, is that it has so many
[774]
co-benefits. That it helps the soils. It helps the farms. It
[777]
helps the watershed. And ultimately should make farms
[780]
more productive and more resilient. But the concerns are,
[784]
how big is this really? Let's be careful about the claims being
[788]
made here and maybe discount them quite a bit until we're
[791]
sure. Because at the end of the day, the atmosphere's balance
[794]
sheet is the one that matters, not ours.
[796]
Hill and Poncia believe that the success of regenerative
[799]
practices may not be driven by the government or the private
[801]
carbon markets.
[802]
I really truly believe that it's going to be consumers that
[805]
demand it of the farmers.
[807]
I think more and more consumers on a daily basis are voting with
[810]
their dollars, supporting people like me and other regenerative
[813]
farmers out there that are doing their best to try and raise that
[817]
nutrient-dense, very health food
