Imagine a rice farmer in Arkansas altering his water management techniques to deliver water more efficiently and use fewer days of flooding, allowing for more precise water and nutrient management while maintaining consistent yields. After a decision by the California Air Resources Board (CARB), in addition to improving water quality and reducing water use and nutrient input costs, that Arkansas farmer now has the option of selling carbon credits to large regulated emitters in California.
In 2012, California put in place a cap-and-trade program for greenhouse gas emissions, one of the most aggressive climate change programs in the world. Last week’s groundbreaking vote by CARB adopted the first crop-based agricultural offset protocol, designed to reduce methane and nitrous oxide emissions from rice production. Methane and nitrous oxide are potent greenhouse gases emitted through the cultivation and fertilization of rice fields. Read more »
A truck is filled with wood chips as part of the process of turning wood into energy.
An industry that can reduce greenhouse gas emissions, increase forest growth, and create jobs sounds too good to be true. But that is the reality of the emerging wood pellets market in the Southern U.S. That conclusion is supported by independent economic assessments of wood bioenergy, including a recent study that specifically focused on European pellet demand conducted by researchers at Duke and North Carolina State Universities. Those researchers found that increasing demand for wood pellets resulted in more forest area, more forest investment, large greenhouse gas reductions, and little change in forest carbon inventories.
So, why is there concern?
Some critics have recently argued that land used to produce biomass for energy should instead be permanently protected as forests. They say that harvesting biomass from forests reduces forest carbon stocks. Instead, they claim that the best way to increase carbon storage is to reduce demand for renewable products that come from the land. Read more »
America’s farmers, ranchers and forest landowners understand the threats that a changing climate can have on their operations and on their bottom line. As the world warms, that warming triggers many other changes to the Earth’s climate, including an increase in extreme events. Over the last 50 years, much of the U.S. has seen increases in excessively high temperatures, heavy downpours, and in some regions, severe floods and droughts. These events can drastically impact the agriculture and forestry sectors.
Today, I announced USDA’s comprehensive plan to tackle these challenges by working with partners and producers on a voluntary basis to reduce greenhouse gas emissions and enhance carbon sequestration in agriculture and forestry by over 120 million metric tons over the next 10 years. Our strategy lays the foundation for agriculture and forestry to be part of the climate change solution. The plan will encourage farmers, ranchers, and forest landowners to set an example for the world by showing that climate-friendly conservation practices can benefit the environment, individual farms and forest operations, and the economy as a whole.

Did you know that carbon dioxide, or CO2, is one of the main contributors to the greenhouse gases that are causing climate change?
And, did you know that one averaged-size tree – say a 30-footer – can store hundreds of pounds of CO2 over its lifetime and even longer if it’s used in building materials for a house or furniture? Read more »

We know that there are climate change risks and vulnerabilities facing agriculture that have significant implications not just for farmers, ranchers, and forest landowners, but for all Americans and the world. That’s why we are working on measures to reduce greenhouse gas emissions and prepare for climate change impacts such as flooding, sea level rise, severe weather and temperature extremes.
Today’s release of the USDA Sustainability Plans and Climate Change Adaptation Plans coincide with the fifth anniversary of President Obama’s 2009 Executive Order on Environmental, Energy and Economic Performance, which set aggressive energy, climate and environmental targets for agencies, and detail how USDA’s actions have already contributed to reducing the Federal Government’s greenhouse gas emissions by more than 17 percent since 2008 – the equivalent of permanently taking 1.8 million cars off the road.

New energy efficient lights in USDA greenhouses at the Western Regional Research Center in Albany (above) will reduce greenhouse gas emissions and save about $200,000 a year in electrical costs. The City of Albany, California recently issued a proclamation recognizing USDA for installing the new LED luminaires and reducing greenhouse gas emissions. Plants in the greenhouses, used for research by Agricultural Research Service scientists, also are growing faster and producing higher yields.
This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.
Sometimes greenhouse gases can be traced to greenhouses—or at least to their lighting systems.
That’s why the Albany City Council recently recognized USDA with a proclamation for reducing greenhouse gas emissions by installing energy-efficient lighting in the USDA greenhouses at the Western Regional Research Center (WRRC) in Albany, California. The greenhouses are used by scientists with USDA’s Agricultural Research Service (ARS), and the retrofit advances the goals of the city’s 2010 Climate Change Action Plan because it reduces citywide electrical use and carbon emissions.
