Greenhouse Gas Emissions


Quiz Questions

1.The term global climate change refers to the destabilizing impact on climate and weather patterns that result from continuous addition of these gases, the resultant increase in heat energy in the earth’s atmosphere, and the associated changes that follow.
True
False
2. A warmer climate increases total demand for electricity, because the increase in demand for summer cooling is expected to outweigh the decrease in winter warming needs.
True
False
3.Landfill sequestration – A portion of waste disposed in landfills is composed of carbon and is not expected to break down, therefore becoming sequestered in the landfill. This is a negative number, which represents carbon dioxide that was absorbed from the atmosphere through respiration during the life of the organic matter and which will not break down in the landfill in the foreseeable future.
True
False
4. _________________ is the year for which the CCP member conducts its emissions inventory.
Base year
Background Year
5.Carbon dioxide equivalent CO2e is a unit that allows emissions of greenhouse gases of different strengths to be added together or compared. For carbon dioxide itself, emissions in tons of CO2 and tons of CO2e are the same thing, whereas for methane, an example of a stronger greenhouse gas, one ton of methane emissions has the same potential effect on global climate change as 21 tons of CO2.
True
False
6.Chlorofluorocarbons are carbon compounds that also contain some chlorine and some fluorine. CFCs do not occur naturally: they are synthetic products used in various industrial processes and also as propellant gas for sprays. CFCs are typically used in refrigerants, solvents, foam-makers, and for use in aerosol sprays. CFCs are significant contributors to ozone depletion and also contribute to global climate change.
True
False
7. The greenhouse effect refers to the increasing warming of the earth because of gases in the atmosphere that trap the sun’s energy on earth. In other words, the sun’s energy passes through to the earth, but more energy than usual is prevented from escaping back into space. This energy remains trapped on earth and gradually warms the earth beyond its normal temperature.
True
False
8. Nitrous oxide is produced through the combustion of fossil fuels and through the production and application of fertilizer used for agriculture. One ton of nitrous oxide has the same potential effect on global climate change as 310 tons of CO2.
True
False
9.The Energy Cost Reduction program (ENCORE) provides for energy conservation and clean technology projects in City facilities.
True
False
10.___________________represents the waste share percentages for government inventory.
Table 2
Table 3
11. The Clean Air Climate Protection (CACP) software used in these analyses calculates a municipality’s greenhouse gas emissions for its target year using that year’s electricity and fuel coefficients.
True
False
12. Figure 19 illustrates the breakdown of energy sources that are responsible for the greenhouse gas emissions from the operation of New York City’s government buildings and facilities.
True
False
13.New York City has already begun implementing measures that contribute to reducing the City government’s greenhouse gas emissions. These measures include energy reduction programs, street tree-planting programs, conversion of streetlights to more efficient technologies, landfill methane recovery, use of alternative fuel vehicles, and solid waste recycling.
True
False
14.Figure 27 illustrates each measure’s contribution to the total annual avoidance of 446,000 metric tons of CO2e emissions.
True
False
15. This emission factor specifies the emissions per kilowatt-hour of the annual average kilowatt-hour produced in the electricity region specified. The average grid electricity emission factor is the average of emissions generated per kilowatt-hour over an entire year, taking into account fuels used and generating and emission control technologies in use in each plant.
True
False
