CO2 is the most contributed gas to the greenhouse effect
accounting for 80% of the impact. CO2 and other gases arise
from combustion of fossil fuels, agricultural activities, industry,
energy use and fertilizers (Ozbayrak et al., 2011). It is
believed that global warming will affect the world even if we
managed to dramatically reduce emissions of GHGs today.
Such trends would continue for a long period, could be decades
or centuries to come (UNEP, 2003). Therefore, cutting
GHGs emissions in order to minimize future climate change
as well as responding to the unavoidable impacts that our past
emissions will cause must be a top priority. The Emission Gap
reports prepared by the United Nations Environment Program
(UNEP) advocate that a universal and collaborative effort to
reduce carbon footprint is the only way to ease the greenhouse effect and reduce the impact of global warming (UNEP, 2013).
Contributions such as saving energy around the house, using
public transportation and renewable energy can help too
(Brown, 2009), but it all starts with raising awareness
