greenhouse gas emissions

Hard to believe 2019 is almost over. With New Year's Eve fast approaching, it's that time of year when many of us take a moment to reflect on all the things we accomplished during the year.

Extreme climate events can be devastating. However, some of their effects can be transformed into opportunities.

Over the past two decades, the demand for renewable fuels — including corn-based ethanol — has helped drive a strong domestic market for corn, and supported rural America by generating jobs (PDF, 1.5 MB). New research is confirming that corn ethanol also has more greenhouse gas benefits than previously thought.

Increasingly, food companies, environmental organizations, and agricultural commodity groups are setting ambitious goals to reduce greenhouse gas (GHG) emissions from farms. These goals are realized through conservation practices such as reduced tillage farming, and precision technologies, like autosteer tractors. Yet, there’s not much nationally consistent data to help farmers and policymakers know which practices are being used, and how the adoption of those practices is changing over time.

Climate projections indicate Puerto Rico may be warmer and drier, likely impacting one of the Island's most iconic crops. This could result in less-favorable growing conditions in the coming decades for coffee. A new study by the USDA Caribbean Climate Hub shows that if greenhouse gas emissions and temperatures continue to increase, we may see a reduction in lands with highly-suitable conditions for coffee. Climate adaptation practices and research can help growers respond to new conditions and keep Puerto Rican coffee growing and flowing.

Ethanol, primarily derived from corn, supplies about 10 percent of US motor fuel needs.  A new study from ICF which was released today, titled “A Life-Cycle Analysis of the Greenhouse Gas Emissions of Corn-Based Ethanol,” finds that greenhouse gas (GHG) emissions associated with corn-based ethanol in the United States are about 43 percent lower than gasoline when measured on an energy equivalent basis.  This is comparable to reducing GHG emissions in the U.S.

Eating a pint of Ben & Jerry’s ice cream may make you feel guilty about your waistline, but thanks to a new partnership between the ice cream company and USDA’s Natural Resources Conservation Service (NRCS), you may be able to feel less guilty about contributing to climate change. The partnership is designed to help Ben & Jerry’s milk suppliers—generally small dairies—understand their greenhouse gas footprint and consider voluntary conservation approaches to reduce that footprint.

NRCS and Ben & Jerry’s will help dairies implement conservation practices that meet Ben & Jerry’s objective of “Happy Cows, Happy Planet, & Happy Farmers.” Through its Caring Dairy sustainability program, Ben & Jerry’s will use USDA’s suite of greenhouse gas estimation tools, COMET-Farm^TM and COMET-Planner^TM, to quantify on-farm GHG emissions and reductions. The COMET tools—COMET stands for CarbOn Management & Emissions Tool – are a product of a long-standing partnership between NRCS and Colorado State University.

By keeping their grasslands intact, two Colorado ranches are reducing greenhouse gas emissions and protecting vital wildlife habitat, all while earning additional revenue.

It may seem too good to be true, but it is thanks to a unique partnership spearheaded by the Climate Action Reserve, one of North America’s leading carbon offset project registries.

With the help of a Conservation Innovation Grant (CIG) from USDA’s Natural Resources Conservation Service (NRCS), the Climate Action Reserve listed Raven’s Nest and Heartland Ranch, both owned by the Southern Plains Land Trust (SPLT), as the first two grassland offset projects developed and executed under a new Grassland Project Protocol.

USDA is bringing tools and solutions to farmers, foresters and ranchers so they have help confronting climate change while working to produce a global food supply adequate to feed the 9 billion people estimated by 2040 while still protecting the earth’s natural resources.

Today, USDA is launching the fifth chapter of USDA Results, telling the story of how USDA has been working since 2009 with partners across the country and around the world to curb the effects of climate change for a healthier tomorrow. Throughout May, we will be announcing new projects and highlight the progress we’ve made under Secretary Vilsack’s leadership, which has made this issue one of his top priorities. Here in the Climate Change Program Office and in Agencies across the Department, we have been busy.

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.
