Johns Manville Corporation, Corporate Greenhouse Gas Inventory Management.
Johns Manville is a Berkshire Hathaway Company that manufactures residential
and commercial insulation and roofing products (www.jm.com).
The company has 40 manufacturing facilities worldwide. MotivEarth conducted
baseline emissions inventory work focusing on two California facilities. The
2006 emissions inventory data was supplied to the California Climate Action
Registry and verified. On a corporate level, MotivEarth is working with Johns
Manville to develop corporate strategies to address climate change issues,
considering energy efficiency and credit development opportunities, national
registry participation, and insulation product sales.
Confidential Independent Power Producer, Greenhouse Gas Emissions Inventory
and Solutions. MotivEarth completed a baseline greenhouse gas
emissions inventory for an independent power producer operating nine plants
with 500 MW of total power production capacity. At six plants, the company
combusts petroleum coke, a fuel with CO2 emissions similar to coal. The company
is facing utility contract renewal, and is concerned that the facilities will
not be competitive to natural gas-fired plants. MotivEarth is working with the
company to analyze possible solutions to reduce GHG emissions ahead of
impending compliance requirements and contract renegotiation. Options reviewed
include boiler oxy-firing, fuel switching, carbon sequestration, load shifting
to re-permitted gas-fired power plants, and plant shutdown. The company is also
considering investing in renewable energy projects to offset GHG emissions from
fossil fuels. The project goal will be to help the company to remain
competitive in the rapidly changing U.S. power generation market.
Project: Oil Production CO2 Life Cycle Analysis, Client: Confidential
Refinery, California. Conducted a life cycle analysis to compare
the CO2 emissions from extraction and delivery of Los Angeles heavy crude oil
to a Los Angeles refinery versus extraction, marine shipping, and delivery of
Alaskan or Middle East light crude oil to a Los Angeles refinery. CO2 emissions
for extraction of Los Angeles heavy crude oil were based on an oil production
lease’s certified California Climate Action Registry emissions. CO2 emissions
calculations from transportation considered heavy fuel oil combustion in main
and auxiliary engines throughout the tanker travel distance, as well as marine
diesel combustion by tugs and during maneuvering and hoteling. Results were
compiled as a production carbon intensity to show that the higher CO2 emissions
from heavy crude oil production in Los Angeles were offset by the reduced
transportation emissions.
