The New Fall Crop for Rice Farmers: Carbon Offsets

rp_robert-200x300.jpgThis September, a new crop will be made available to rice producers: carbon offsets.

The California Air Resources Board (ARB) took another important step forward last week when it published the latest draft standard for the development of carbon offsets. The standard lays out the steps a producer needs to take in order to sell his new crop. Once it is approved, producers will be able grow and sell it as a new revenue stream.

So how does this work?

Rice fields are flooded as a part of growing this worldwide staple. It’s necessary for its growth. However, when water comes in contact with organic matter, the organic matter decomposes, generating methane – a strong greenhouse gas. By reducing the amount of methane generated through rice cultivation, a farmer can generate a carbon credit that can be sold to companies to offset their carbon emissions.

Fertilizer-Efficiency Credits Seed the Market for Agricultural Offsets

Robert ParkhurstFertilizer use is key to increasing the productivity necessary for farms to feed rising populations.  However, not using the right amount in the right place at the right time is one of the biggest threats to a stable climate. Nitrogen fertilizer not used by crops emits nitrous oxide, a heat-trapping gas 300 times more powerful than carbon dioxide. It also contaminates water supplies, causes algae blooms downstream and erodes soil health.

So, it was welcome news last week when the first greenhouse gas credits for fertilizer efficiency made their debut in the North American carbon market.

The American Carbon Registry issued the credits to Myron Ortner, a central Michigan farmer who voluntarily reduced nitrous oxide emissions from his crops by modifying his fertilizer use. Working closely with researchers at Michigan State University, Ortner tested fertilizer inputs on a 40-acre plot where he grows corn and soybeans in rotation. In an interview with Scientific American, he said he’s down to using 135 pounds of fertilizer per acre, less than the average 200.

"I found out we can use less nitrogen and get away with it through those studies," Ortner told the publication. "I want a few more years on it before I'm going to commit all my acres to it, but I don't think I've lost any yield by doing what we're doing." Read More »

Spreading Good News About the Compost Protocol

robertThere’s a growing excitement around spreading compost on rangelands to help fight climate change. Over the past four years we have learned that grazed rangelands are really good at pulling carbon out of the air and sequestering it in the soil below. And if you add compost just one time, you can capture carbon dioxide from the atmosphere for more than seven years. Plus, you’ll  increase  both the quality of the grasses and the ability of the soils to hold water. If we scaled this to just 5 % of California’s rangelands, we could capture approximately 28 million metric tons of carbon dioxide per year, which is about the same as the annual emissions from all the homes in California.

To measure the capture of CO2, we collaborated with Terra Global Capital to create a protocol to calculate the amount of CO2 and enable ranchers to generate carbon offsets which they can sell on the voluntary carbon market. Right now we’re  in the middle of a public comment period for this protocol –  Emissions Reductions from Compost Additions to Grazed Grasslands. After public comment is over the protocol will go through a peer review period, and then be approved and published by the American Carbon Registry.  A copy of the protocol and instructions for providing comments is available here.

This protocol quantifies the emission reductions from diverting organic materials from landfills and spreading it on rangeland to spur carbon capturing grass growth. Recent waste studies estimate that approximately 72% of the waste stream going to landfills is organic (6% wood, 7% textiles/leather, 13% yard debris, 12% food scraps, 34% paper). By accurately measuring how much we divert and sequester, we can also correctly reward landowners for their good work. With our partners, University of California at Berkeley and the Marin Carbon Project, we’ve already seen the beneficial impacts through pilot projects on rangeland in Marin, Sonoma, and Yuba counties.

Spring Cultivates Rice Offsets

rp_robert-200x300.jpgThe arrival of Spring can’t come soon enough for some, though it came early for the California offset market.  Three significant events will spur the development of carbon offsets from rice cultivation.  First, the California Air Resources Board (ARB) launched a rulemaking to adopt a compliance offset protocol for rice cultivation projects.  The American Carbon Registry (ACR) also approved a rice protocol for the Mid-South (Arkansas, Louisiana, Mississippi, Missouri and Texas).

And at EDF we announced the listing of the first California rice offset project with ACR.

As a part of ARB’s rulemaking, they released a discussion draft of a compliance offset protocol.  This protocol contained three different activities that growers can take to reduce the generation of methane associated with rice cultivation – dry seeding, early drainage, and alternate wetting and drying of fields.  All of these practices have been developed using the latest science and have been shown to reduce methane generation without impacting yield.  Methane is the second largest anthropogenic source of greenhouse gas (GHG) emissions, accounting for 9% of all U.S. GHG emissions from human activities.  Methane is also important because it is more than 20 times more potent a GHG than carbon dioxide.  At the meeting, the ARB stated that they intend to propose the protocol for consideration at the September 2014 Board meeting.

Plow, or Preserve and Profit?

Konza Prairie Biological Station

This weekend, long-time Minneapolis Star Tribune outdoors columnist and reporter Dennis Anderson wrote a revelatory call to arms about the dire state of conservation in Minnesota:

"This ain’t working, and we need to try something different. Radically different."

Directly to the West of Minnesota in the Prairie Pothole Region of Montana, North Dakota and South Dakota, annual losses of native grasslands have averaged approximately 50,000 acres per year since 2007, leading to a significant loss of soil carbon. High prices for commodity crops make it much more attractive to plow grasslands than to keep them intact.

What if a market-based initiative paid farmers and ranchers for keeping grasslands grass? A new carbon offset protocol announced yesterday may just do that.

The protocol officially titled the “Avoided Conversion of Grasslands and Shrublands to Crop Production” was developed through a partnership effort including Environmental Defense Fund, Duck’s Unlimited, The Climate Trust, The Nature Conservancy and Terra Global Capital and was funded in part by the U.S Department of Agriculture’s Conservation Innovation Grant.

Just approved by the American Carbon Registry, this first of its kind voluntary protocol will be best applied to grasslands in the Midwest. Producers of these offsets can sell them to any willing buyer in America. Ranchers in the Midwest already recognize the value of their land lies in the soil health below ground where the soil translates to healthy food for their cattle. Now these same producers can quantify this value and sell it through new environmental markets.

“This project provides Northern Great Plains producers with new ways to earn income from conservation activities, expanded opportunity for outdoor recreation and an opportunity to create jobs in their communities,” said Robert Bonnie, USDA Under Secretary for Natural Resources and the Environment. “The American Carbon Registry’s approval of this innovative ACoGS protocol enables vital projects like our partnership with Ducks Unlimited to preserve a treasured national landscape, while also preventing the release of greenhouse gas emissions.”

This first project the Under Secretary mentions, is estimated to perpetually conserve 5,000 – 6,000 acres of native mixed-grass prairie. The protection of grasslands will also indirectly protect 500-600 acres of seasonal and semi-permanent wetlands situated in the protected grasslands.

And these lands are protected not through onerous regulations or hollowed out federal conservation programs but through innovative new revenue streams for the agriculture sector from emerging environmental markets such as California’s carbon market.  Between now and 2020, companies in California can purchase more than 200 million metric tons of offsets.  This protocol has the opportunity to help supply that demand.

This is an exciting step forward for Midwest producers. By making ecosystems a part of the economy ranchers and their families will benefit from diverse opportunities to make more money off their land.

611,622 Offsets and Counting!

Yesterday the California Air Resources Board (CARB) delivered a total of 611,622 offsets to four offset project operators.  These offsets can now be used by California compliance entities to meet their obligations under the cap-and-trade requirements of California’s Global Warming Solutions Act of 2006 (AB 32).

This is an historic accomplishment for California.  Not only are these the first compliance offsets to be generated for the state’s landmark cap-and-trade program, but it sends a strong signal to compliance entities that there is supply.  It also creates a win-win for developers, like U.S. farmers and ranchers, giving them  the opportunity to generate a new revenue stream for their operations while helping California fight pollution in the process.

EDF looks forward to the further offset issuance from CARB.  There are 62 Early Action Projects under review and we expect those credits to be issued in the upcoming weeks.  In addition to Early Action Projects, offset project operators can develop projects under one of the four CARB compliance offset protocols – Forest, Urban Forest, Livestock, and ODS.  This is an exciting time for the cap-and-trade program.  Offsets are valuable, high quality reductions that have already been achieved.  As Board Chair Nichols said “These offsets have undergone the most rigorous verification of any existing program. They achieve real greenhouse gas reductions under ARB-approved protocols, and deliver a range of additional environmental benefits."
