Implications of Climate Change on Beet Sugar Manufacturing
Climate Change
Global Warming is Occurring Greenhouse Gasses are increasing Correlation is there Convincing evidence for causal
relationship Implications are uncertain Governments are acting
Greenhouse gas concentrations in the atmosphere will increase during the next century unless greenhouse gas emissions decrease substantially from present levels. Increased greenhouse gas concentrations are likely to raise the Earth's average temperature, influence precipitation and some storm patterns as well as raise sea levels. The magnitude of these changes, however, is uncertain.

Implications of Warming Longer Growing Season
Longer cool spring and fall Larger beets More Tons
Hotter Summers More water More nutrients
Warmer Winters Poor beet storage
Possible Actions Decrease Acres Increase Daily Slice Increase Juice Storage More protection for stored
beets
Precipitation
Implications for Extremes in Annual Precipitation
Dry Years Small crops Expensive water Stressed beets
Wet Years Small crops Muddy beets Stressed beets
Possible actions Reduce Labor Force Dirt and mud equipment

EPA Endangerment Finding 12/7/2009
The Administrator finds that the current and projected concentrations of the six key well-mixed greenhouse gases--carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O),
hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)--in the
atmosphere threaten the public health and welfare of current and future generations.
GHG Reporting Requirements
September 22, 2009 Who Must Report
Suppliers of fossil fuels or industrial greenhouse gasses
Manufactures of vehicles and engines Facilities that emit 25,000 metric tons or more
of GHG
GHG Tailoring Rule
Issued May 13, 2010 Establishes thresholds for GHG for
New Source Review (NSR) Permits Title V Permits
Covers 70% of GHG emissions from stationary sources
Minnesota
Thu Feb 22, 10:55 AM ET
ST. PAUL, Minn. - Minnesota has a new law that will require utilities to use wind, sun and cleaner-burning fuels to produce a quarter of the state's electricity by 2025, a standard that advocates called among the most aggressive in the country.
Possible Financial Assistance
DOE and USDA Award $17 Million via Joint Biomass Research and Development Initiative
Greenhouse Gas Taxes?
Boulder Voters Approve Greenhouse-Gas Tax Nov 9, 2006 8:37 am US/Mountain (AP) BOULDER, Colo.
Voters in Boulder have overwhelmingly approved a "climate tax" on businesses and residents as part of a plan to lower the city's greenhouse-gas emissions by about 25 percent.
The tax, based on energy consumption, passed with a 59 percent majority.

Opportunities for Energy Reduction in Sugarbeet Production Harvest and Storage
Crop Improvements Genetic Engineering Sugar Content Higher Yields
Technology Dirt removal Chip recovery
Beet storage management
Minimize hauling Larger payloads Piler location
Other Opportunities for Greenhouse Gas Reduction
Biomass for fuel Wastes as products Beet top utilization Ethanol from pulp, molasses or
wastes
Summary
Beet sugar industry has opportunities to keep in step with climate-change reduction efforts
Efficiency is a big part Much research, development and
investment is required
