2. Introduction
 New York-based financial professional Jay Zises serves as
chairman of Associated Capital, an investment management
firm for high net worth individuals. Alongside his work with
Associated Capital, Jay Zises contributes to a wide range of
nonprofit organizations including the Environmental Defense
Fund.
The Environmental Defense Fund is a nonpartisan
organization dedicated to science-based environmental
stewardship. It works to bridge the divide between economic
interests and environmental concerns by supplying mutually
beneficial solutions to contemporary problems.
One of the Environmental Defense Fund's current campaigns
centers on curbing methane emissions. Methane is a
greenhouse gas, and its short term potency is 84 times that
of carbon dioxide. Methane is also a key component of
natural gas.

3. Environmental Defense Fund
 Approximately 25 percent of human-caused
global warming is caused by methane
emissions. When methane leaks into the air, it
absorbs heat from the sun and contributes to
atmospheric warming. In order to combat the
leaks that cause these emissions, the
Environmental Defense Fund conducted a 30-
month study to identify the sources of this
contamination. Google Earth Outreach
contributed to this project, resulting in
interactive maps of methane leaks and
ongoing solutions.
