The Livestock GRACEnet mission is to develop livestock management practices that reduce greenhouse gas emissions and provide accurate measurement and modeling of emissions. The group aims to collaborate with scientists and stakeholders, support policymakers with consistent data, and efficiently share new knowledge. Livestock GRACEnet includes 24 scientists across 13 locations focusing on beef, dairy, poultry and swine emissions. The goals are to create emissions measurement protocols, develop factsheets on management practices, build an emissions database, enhance scientist collaboration, and interact with agencies on emissions information. The website provides factsheets and information on the group's work measuring and reducing livestock emissions.

2. Livestock GRACEnet Mission
…to lead the development of livestock management
practices to reduce greenhouse gas, ammonia, and other
emissions and provide a sound scientific basis for
accurate measurement and modeling of emissions.
We will:
• Collaborate with fellow scientists and stakeholders to identify
and develop appropriate management practices
• Support the need of policy makers and regulators for
consistent, accurate data and information
• Foster scientific transparency and rigor
• Transfer new knowledge efficiently to stakeholders and the
scientific community

4. Livestock GRACEnet Goals
• Methods manual: provide protocols and methods for
measuring on-farm emissions given a variety of available
equipment and production systems.
• Factsheets: Develop two page factsheets describing
management practices that can be used on-farm to reduce
emissions
• Database: Develop a database containing emissions data from
a variety of livestock production systems in various regions
that can be used for model development and validation.
• Enhance collaboration between scientists: Provide a network
and vehicle for multi-location projects.
• Interact with other agencies: Provide a consensus response to
agencies requiring information related to emissions.

7. Future Livestock GRACEnet
There has been interest from the Global Research
Alliance to open the group up to any interested
parties….
Paddy rice Livestock Crops
Livestock Research Group
• Improve the greenhouse gas intensity of livestock production systems
• Increase the quantity of carbon stored in those soils
• Key emissions covered:
• methane from enteric fermentation and waste management
• nitrous oxide from animal wastes and fertilisers

Today’s session
Nine presentations that will highlight some of the work
being done by our scientists
Two additional presentations from collaborators.
Special JEQ Issue
There will be a special issue of JEQ that features work
being don by the Livestock GRACEnet group which will be
out late this year.
