In order to reduce the emission of gases such as sulfur dioxide, oxides of nitrogen and carbon monoxide, we first have to know the sources of these gases before we can truly know how to reduce the emissions of such gases.
For example, sulfur dioxide is formed when fossil fuel are burnt and sulfur inside the fossil fuel is converted to sulfur dioxide. Thus, in order to reduce emission of sulfur dioxide, we first have to reduce the burning of fossil fuel, which is by reducing our usage of electricity. For example, besides just switching on the fan instead of air-con, there are many other things we can do. Many of our families use water boilers that require energy to keep the water inside it warm for drinking. Instead of doing so, we can actually use a kettle to boil the water and then store the water inside a hot water flask. Although the water will cool, it will take a long period, and additionally, saving electricity since it is not needed to keep the water warm.
Oxides of nitrogen are formed in car engines due to the high temperature causing nitrogen to combine with oxygen. In order to reduce emission, we firstly have to cut down on the number of active car engine on the road. The question is, how? Well, we firstly have to cut down on the amount of car sold in order to cut down on the number of active car engine. This can be done by raising the prices of COEs and cars for people who are buying their second car for the family. This will not only allow each family to have a car, but also reduce the amount of car on the road. With the increased prices, families will be discouraged to buy more cars, and this in turn will gradually lower the number of active car engines on the road and ultimately, emission of oxides of nitrogen.
Lastly, the emission of carbon monoxide comes from the incomplete combustion of petrol in car engines. Thus, to reduce on the emission, we firstly have to cut down the use of petrol. One way is to mass produce hybrid and electric cars which rely more on electricity to be powered rather than petrols. By mass producing, the prices of hybrid and electric cars will be lowered and the price of petrol-powered cars will be more expensive. This will thus encourage more people to buy electric and hybrid cars than petrol-powered ones. Thus, with a reduction in the usage of petrol, there will be lesser incomplete combustion of petrol and a lower emission of carbon monoxide.
Sulfur dioxide is produce mainly due to burning of fossil fuels for electricity thus, to reduce sulfur dioxide, the individual must conserve electricity. This can be done by using fans instead of air conditioners, switch off lights when it is not needed, adjust air conditioner temperature to 25 degrees Celsius or above, unplug or switch off appliances when unused, when cooking leave the lid on to keep the heat in, etc. This means that less fuel is burnt and less sulfur dioxide is produced.
The application of fertilizers accounts for the majority of N2O emissions. Emissions can be reduced by reducing nitrogen-based fertilizer applications and applying fertilizers more efficiently, as well as following better manure management practices. Nitrous oxide is a byproduct of fuel combustion, so reducing mobile fuel consumption in motor vehicles can reduce transportation emissions. Additionally, the introduction of pollution control technologies, such as catalytic converters to reduce exhaust pollutants from passenger cars, can also reduce emissions of N2O. Nitrous oxide is generally emitted from industry through fossil fuel combustion so technological upgrades and fuel switching are effective ways to reduce industry emissions of N2O. Production of adipic acid results in N2O emissions that can be reduced through technological upgrades.
Ways to reduce carbon monoxide are as follows. Do not use the oven of a gas kitchen stove for heating. Avoid use of charcoal grills indoors for cooking or to eliminate the chill in a room or closed garage as they give off CO fumes, even when no glow is visible in the coals. Provide a constant supply of fresh air for safe burning of fuels. This can be done by leaving a window slightly open. Be sure the doors are open in the garage or enclosure where an automobile motor is running.
Ways to reduce carbon dioxide emissions Recycle, re-use and avoid useless purchases. We throw too much away and still re-cycle too little of what we must discard. Large amounts of energy and water go into producing endless amounts of ‘stuff’, much of which we don’t really need or end up using. So be sure to use your local recycling service, for plastics, metals and paper. Try to get appliances and tools fixed rather than replaced – the carbon footprint of fixing things is far lower than making them from scratch. Avoid the temptation to buy useless trinkets and knick-knacks, just because it feels good to accumulate things. There are limits to everything, including, most importantly, the ability of the planet to supply people with an ever burgeoning supply of raw materials. Think sustainability.
Ways to reduce Oxides of Nitrogen emissions The application of fertilizers accounts for the majority of N2O emissions. Emissions can be reduced by reducing nitrogen-based fertilizer applications and applying fertilizers more efficiently, as well as following better manure management practices.
One of the ways to reduce carbon monoxides that we can do is to eat less red meat. Traditional red meat comes from ruminant livestock such as cattle and sheep. These animals produce large amounts of methane, which is a greenhouse gas that packs 72 times the punch of CO2 over a 20 year period. Other types of meat, such as chicken, pork or kangaroo, produce far less emissions. At average levels of consumption, a family’s emissions from beef would easily outweigh the construction and running costs of a large 4WD vehicle, in less than 5 years. There is no need to cut out red meat entirely, but fewer steaks and snags mean far less CO2.
The other way is to buy energy and water efficient appliances. Aside from behavioural change, we can invest in more sensible technologies that help us in our day to day lives. When buying new electronic appliances, air conditioners or washing machines, look at their energy and water usage. The more energy efficient they are, the more they’ll save you in the long run, and the lower their CO2 impact will be.
