Natural gas“Twice as clean as coal”
![Page 10: ‘Shale’ Natural Gas A Global Warming Solution Jeffrey McManus Chesapeake Climate Action Network](https://reader034.vdocument.in/reader034/viewer/2022042821/56649d805503460f94a64fda/html5/thumbnails/10.jpg)
Half as dirty
![Page 11: ‘Shale’ Natural Gas A Global Warming Solution Jeffrey McManus Chesapeake Climate Action Network](https://reader034.vdocument.in/reader034/viewer/2022042821/56649d805503460f94a64fda/html5/thumbnails/11.jpg)
Half as dirty
It is still a fossil fuel
![Page 12: ‘Shale’ Natural Gas A Global Warming Solution Jeffrey McManus Chesapeake Climate Action Network](https://reader034.vdocument.in/reader034/viewer/2022042821/56649d805503460f94a64fda/html5/thumbnails/12.jpg)
Misleading Comparison
• Combustion is the last stage
• Natural gas life cycle– Exploration, Production, Processing, Transport,
Storage, Distribution, Combustion
• Direct, Indirect, & Fugitive Emissions
![Page 13: ‘Shale’ Natural Gas A Global Warming Solution Jeffrey McManus Chesapeake Climate Action Network](https://reader034.vdocument.in/reader034/viewer/2022042821/56649d805503460f94a64fda/html5/thumbnails/13.jpg)
Problem: Unburned natural gas
• Methane– Potent greenhouse gas– Gas drilling = 1/5th global emissions (human-caused)
• 100 years– 25 times worse than CO2
• 20 years– 72 times worse than CO2
• Why 20 years?
![Page 14: ‘Shale’ Natural Gas A Global Warming Solution Jeffrey McManus Chesapeake Climate Action Network](https://reader034.vdocument.in/reader034/viewer/2022042821/56649d805503460f94a64fda/html5/thumbnails/14.jpg)
Fugitive Emissions
• Even small leakages into atmosphere have very large global warming consequences
• Sources of fugitive emissions– Leaks– Intentional venting
• U.N. Environment Program– CO2 reductions over 20-30 years – no impact on 2
degree change by 2050– Methane & “Black Carbon” reductions
immediately felt. Delay until 2070

Natural gas can serve as a ‘bridge fuel’ as we transition to
renewable sources.

America’s Blind Jump
• Lobbying for subsidies and guarantees to make gas an indispensible energy source
• Creating a market for the supply– Generation: new power plants built to run on gas• $2 million and three years
– Transportation: natural gas vehicles– Aviation: natural gas planes
• Industry’s ‘infrastructure trap’– “Switching the needle”
![Page 25: ‘Shale’ Natural Gas A Global Warming Solution Jeffrey McManus Chesapeake Climate Action Network](https://reader034.vdocument.in/reader034/viewer/2022042821/56649d805503460f94a64fda/html5/thumbnails/25.jpg)
Look before you leap• What’s at risk?– Environment, Public Health, Climate– $ Billions taxpayer and industry investment spent for
limited/no gain• Unanswered questions– Let’s pause before making major policy decisions– Decide based upon science, not industry rhetoric– EPA Fracking Life-Cycle Study
• No rush– The shale gas is not going anywhere soon– Wait for better technology
• Federal lands

Don’t Frack with Maryland
• HB 852 The Marcellus Shale Safe Drilling Act of 2011
• Pause until July 2013• Puts onus on gas companies

A Truly Clean Alternative• Criterion wind farm
– 70 MW– 162 mostly local & union workers– $10 million shot into economy– $1.1 million in utility tax revenue (2nd largest)
• Maryland Offshore Wind Energy Act of 2011– 400-600 MW– 79% Eastern Shore homes– 2,000 manufacturing & construction jobs (5 years)– $1.9 Billion economic impact (5 years)– 8,200 job-years– $14 million in state tax revenues– 400 operations and maintenance jobs– Cost -- $1.44/month =replace two 60W bulbs w/ Compact
