Economic Analysis of Cap-and-Trade Legislation’s
Impact on Agriculture
There
is much discussion about the economic impact on agriculture of the American
Clean Energy and Security Act (ACES). This Act was passed by the U.S. House of
Representatives in 2009. The ACES establishes an economy wide cap-and-trade
program. The cap gradually reduces covered greenhouse
gas emissions to 17 percent below 2005 levels by 2020, and 83 percent below
2005 levels by 2050. Under ACES, capped entities could purchase offsets
to meet compliance obligations. Domestic and international offsets would be
allowed up to a total of 2 billion metric tons of greenhouse gas emissions
annually. Agriculture and forestry can serve as offset providers, and the USDA
would oversee the offset program for these industries. Currently, the bill
allows for emissions to be offset by:
*
Soil carbon sequestration
*
Animal waste methane capture
*
Nitrous oxide reductions from fertilizer application
*
Afforestation carbon sequestration
*
Forest management carbon sequestration
Some
of the important questions for agricultural producers are:
1.
How much will carbon credits be worth?
2.
How much could production costs increase through higher energy costs?
3.
What about those in the agriculture and forest industries who are unable to generate
carbon credits?
One of the factors to
consider when evaluating the potential costs to agriculture of the
cap-and-trade legislation is the potential cost in the absence of legislation.
If no federal legislation is passed to control greenhouse gases, the EPA now
has the authority to regulate CO2.
The Supreme Court ruled in
2007 that the EPA has the authority to regulate carbon dioxide emissions but
that the agency must first determine whether carbon dioxide presents a threat to
the public. This finding would give the federal agency the authority to regulate
carbon dioxide from vehicles and potentially from stationary facilities around
the
The
following is a brief summary of the currently available economic analyses of
ACES.
USDA Analysis

ACES will likely have small but significant effects on crop and
livestock producers. Over the short run, impacts are largely negligible due to
the “energy-
intensive, trade exposed entities” (EITE) provisions
of the bill which would shield producers from the effects of higher natural gas
prices on fertilizer prices. After 2025, however, fertilizer prices would
likely increase. While energy-intensive crops will be most affected, the
legislation also provides significant opportunities to offset increased costs
through carbon sequestration activities. Greater demand for renewable
electricity will put upward pressure on the demand for biomass and provide an
added source of farm income.
The increases in energy prices cause the variable cost of
production to increase for all crops. The extent of the price increases above
the baseline levels ranges from an average of 0.3 percent for upland cotton to
0.9 percent for sorghum. Most of the impacts are felt through increased fuel
costs. Thus, those crops where fuel costs are proportionately higher showed
larger impacts (e.g., rice, sorghum.) Total farm production expenses could rise by 0.3 percent,
in the near term.
ACES
would also provide opportunities for farmers and ranchers to receive payments
for carbon offsets. EPA’s analysis indicates that in 2020 agricultural lands
would supply 70 million tons of CO2e offsets through changes in tillage
practices, reductions in methane and nitrous oxide emissions, and tree planting
(afforestation). By 2050, agricultural lands could supply 465 million tons of
CO2e reductions and existing forests supply an additional 178 million tons of
CO2e reductions. This could generate gross domestic agricultural and forestry
offset revenues of $2 billion per year in real 2005 dollars in the near term,
rising to about $28 billion per year in real 2005 dollars in the long term.
USDA’s analysis strongly suggests that revenue from agricultural offsets
(afforestation, soil carbon, methane reduction, nitrous oxide reductions) rise
faster than costs to agriculture from cap and trade legislation. It appears
that in the medium to long term, net revenue from offsets will likely overtake
net costs from HR 2454, perhaps substantially.

Carbon
credits will initially have a value of $15 per ton of CO2
equivalent, and this value will rise slightly each year after the program takes
effect. There will be a 50% increase in the percent
of cropland using conservation-tillage and no-till by 2020 in response to a
$15/ton CO2 incentive payment.
Overall land area in crops will decline due to an increase in afforestation.
Reductions in fertilizer
use will result in declines in yields. If fertilizer application can be
improved without yield penalties, the potential for emissions reductions will
be higher.
Prices
for petroleum, electricity, and natural gas could rise above baseline levels by
4.0 percent, 12.7 percent, and 8.5 percent, respectively, by 2020. As the
limits on greenhouse gas emissions become more constraining over time, the
impact on energy prices becomes more significant. By 2035, prices for
petroleum, electricity, and natural gas could rise above baseline levels by 7.2
percent, 14.3 percent, and 16.9 percent, respectively. By 2050, petroleum
prices could be almost 15 percent above baseline prices, while natural gas and
electricity prices could exceed baseline levels by over 30 percent.

There are many uncertainties
to take into account when trying to project future energy costs under the ACES
Act. Across all main analysis cases (see the web site above for all the
assumptions involved), allowance prices range from $20 to $93 per metric ton in
2020 and from $41 to $191 per metric ton in 2030. The lower prices in the range
occur in cases where technological options such as Carbon Capture and Storage
and adoption of new nuclear power plants can be deployed on a large scale
before 2030 at relatively low costs, and/or the use of international offsets
helps to hold down compliance costs. Higher allowance prices occur if
international offsets are unavailable, among other possibilities.
ACES
increases energy prices, but effects on electricity and natural gas bills of
consumers are substantially mitigated through 2025 by the allocation of free
allowances to regulated electricity and natural gas distribution companies. In
most future scenarios, electricity prices range from 9.5 to 9.6 cents per
kilowatt-hour in 2020, only 3 to 4 percent above the Reference Case
level. Average impacts on electricity prices in 2030 are projected to be
substantially greater, reflecting both higher allowance prices and the
phase-out of the free allocation of allowances to distributors between 2025 and
2030. By 2030, electricity prices in the ACES Basic Case are 12.0 cents per
kilowatt-hour, 19 percent above the Reference Case level.

estimated by CRA International (http://www.nationalbcc.org/images/stories/documents/CRA_Waxman-Markey_%205-20-09_v8.pdf).
