emission trading - Answers bringing new parts to less efficient countries to increase efficiency. it is paid
for and then claimed for credit of emission reduction.
biomass - Answers replanting forests to offset Carbon sinking. advantages: increased employment,
increased security of energy, increased fossil fuel lifetime, net carbon dioxide neutral, less pollution.
methane - Answers contributes to increased concentration in atmosphere. capture the methane for use
instead of allowing leaks. livestock and landfills contribute the most leakage.
sequestration - Answers locking away CO2 to keep it from entering the atmosphere. storage of CO2:
ocean, minerals, depleted oil and gas wells, brine fields, coal fields, carbon sinks. power plants: air mixed
with nitrogen... we want the oxygen but it's costly to separate.
sequestration: the ocean - Answers need more plankton to fertilize and trap CO2 as they decay for
carbon cycle. this is a carbon sink, there's more carbon in the ocean than in the atmosphere.
3 processes of ocean sequestration - Answers 1. carbon sink through fertilization 2. inject CO2 into
ocean to form hydrates 3. inject CO2 into bottom of ocean to form CO2 underwater lake.
sequestration: oil fields - Answers small holes in oil fields can be filled with CO2. if the field is still
producing the gas aids in extraction of crude through pressure. otherwise cap the methane leaks.
sequestration: brine fields - Answers saline formations. estimated saline storage capacity in the US is
large and most existing CO2 point sources are within easy access to a saline injection point. Sleipner
West Heimdel gas reservoir of the Norwegian oil company Statoil is the only commercial CO2 geological
sequestration facility.
sequestration: coal - Answers large cracks and pores in coal allows permeability. CO2 is attracted to the
coal micropore and doesn't need much space to bounce around, it wants to associate so we can fill
more volume than we could with empty space. kicks out methane too, sequester coal, collect methane.
cost is slightly high and would increase the cost of electricity.
conservation - Answers if we conserve, we use less, if we use less, we pollute less.
reduction - Answers achieved through economic depression, kind weather.
reducing N2O - Answers NOx consists of NO N2O and NO2. N2O is the greenhouse gas of the three.
solutions include: NOx removal (acid deposition), mitigation, prevention are applicable to N2O.
nuclear - Answers % of power supplied will decrease. output will remain the same but % contribution
will decrease and decommissioning reactors and plants will result in a loss of capacity.
smog - Answers ground level ozone. it's harmful.
