Higher Gas Prices Mean Greater Cost Savings from
Reducing Methane Emissions
Natural gas has never been a more valuable
commodity! With elevated gas prices and
demand at an all-time high, some gas
companies may see a welcome boost to
profits. Today's high prices also mean that
operators are likely to have additional cost-
effective opportunities to reduce methane
emissions and increase gas sales.
With annual industry-wide emissions estimated at
312 Bcf and well-head prices averaging $4.00/Mcf
and higher, approximately $1.2 billion of natural
gas are lost to the atmosphere each year. Now is
a good time to take a second look at gas leaks
and losses that were not economic to address
at lower prices, (continued on page 2)

Higher Gas Prices
Mean Greater Cost
Savings
continued from page 1
Historically, Natural Gas STAR has
used $2.00/Mcf to calculate savings
and evaluate economic opportunities
from methane emission reduction
technologies and practices. Given
today's higher gas prices, potential
savings are even more impressive,
and payback periods are significantly
shorter. The table on page 1
demonstrates possible savings and
payback periods for selected STAR
Best Management Practices and
Partner Reported Opportunities,
using gas prices of $4.00/Mcf and
$6.00/Mcf.
We hope this information will
encourage you to consider which
practices and technologies will boost
your company's bottom line.
To showcase the methane reduction
efforts of Gas STAR Partners and
promote the Natural Gas STAR
Program, this public service
announcement appeared pro bono
in the December 1999 issue of
Pipeline & Gas Industry and in the
March 2000 issue of American Gas.

Mitigating Greenhouse Gases:
State of New Jersey First To Implement Action Plan
With the unveiling of its
Sustainable State Project
on April 17, 2000,
New Jersey became the
first state to establish a goal for
greenhouse gas (GHG) reductions with
specific milestones. Last year, the New
Jersey Department of Environmental
Protection (NJDEP) committed to
cutting state GHG emissions by
3.5 percent below 1990 levels by
2005. The plan calls for reducing
emissions by about 20 million tons
through five initiatives: energy
conservation, pollution prevention,
innovative technologies, recycling
and solid waste management, and
natural resource protection. New
Jersey produces about 2 percent of the
nation's greenhouse gases (about
130 million tons a year). If no action is
taken, emissions are projected to rise
6 percent annually.
On February 12, all 56 New Jersey
colleges and universities agreed to
implement programs to help reach
the state's 3.5-percent GHG reduction
target. State Environmental Protection
Commissioner Bob Shinn is now
working to develop environmental
partnership agreements with cities
and counties that contain a similar
commitment to GHG reductions.
The City of Bayonne and Hudson
County have already signed on;
three more agreements are in draft
stages. Joe Genovay, Office of the
Commissioner, notes that Shinn plans
to create a statewide program through
these agreements.
Strategies to address greenhouse gases
include the following:
• Establishing incentives that
encourage voluntary reductions,
such as a banking and trading
system for carbon dioxide emissions
• Promoting energy efficiency
through the Open Market Emission
Trading Program and requiring
power suppliers in the forthcoming
deregulated electricity market
to disclose energy efficiency
information
• Addressing mobile sources of
carbon dioxide emissions
• Reducing landfill methane
emissions
• Promoting and establishing
incentives for the use of renewable
energy technologies, including
geothermal, fuel cells, wave, solar,
methane from landfills, biofuels and
biomass used in the transportation,
heating/cooling and energy
production sectors
The state's action plan follows on the
heels of an incentive program for
permit applicants established by NJDEP.
The program seeks to reduce GHG
emissions and achieve higher levels of
pollution prevention. The Silver and
Gold Track Programs for Environmental
Excellence offer regulatory flexibility to
companies with superior track records
in exchange for a covenant committing
to specified environmental gains. Five
applicants have signed up for these
programs since they were announced
in late 1999.
Natural Gas STAR strives to keep
Partners informed about greenhouse
gas and climate change-related
developments at the state and
federal levels.
For more information on New Jersey's
greenhouse gas action plan,
contact Mike Winka, NJDEP, at
(609) 292-9962. For more information
on the partnership agreements,
contact Joe Genovay, Office of the
Commissioner, at (609) 633-1238.
