Greenhouse Gases and our Sustainability Efforts

Posted on by

Greenhouse gases contribute to many dangers in sustainability efforts and these greenhouse gases have been closely monitored by the EPA, with the government organization monitoring the rises and sinks of greenhouse gas emissions and the biggest contributors to greenhouse gas emissions in the United States.  I believe that sustainability efforts should first and foremost look to reduce the amount of CO2 and other greenhouse gas emissions that we are placing into the world.  The US emissions totaled 5,222 million metric tons of CO2 equivalents in 2020.  This is an 11% decrease from 2019 with the total change from 2019 to 2020 decreasing from 5796.42 million metric tons to 5222 metric tons.  This resulted in a 574.42 million metric ton decrease in CO2 emissions.  This was largely due to the pandemic  as well as the continued search for more renewable and sustainable forms of energy.

One interesting topic I found regarding sustainability GHG emissions, especially CO2 emissions is electric cars.  While electric cars are better for the environment, the deciding factor on the sustainability is how much is required to produce these electric cars.  An all electric Chevrolet Bolt produces 189 grams of CO2 for every mile, as opposed to a gas fueled Toyota which produces 385 grams of CO2 per mile.  However the challenge comes in the production of electric cars and the energy grid.  It is important to understand that just because a car is electric might not mean it is as sustainable as it seems.  This issue concerning electric cars relates back to my main point earlier about greenhouse gas emissions.  We as people need to look to find the best possible solutions to decrease the harm we are doing to our planet.

Carbon Dioxide Levels are Increasing Yearly

Carbon dioxide has a heavy impact on the atmosphere of the Earth and is proven to affect climate change, global warming, and the ecosystems for the future. With the increase of carbon dioxide in the atmosphere, this is an issue to the energy imbalance which leads to the Earth’s temperature to increase; global warming. Due to human interactions and human life, there will always be carbon dioxide being released in different forms into the atmosphere, but there needs to be a way to reduce this amount of carbon dioxide for the wellbeing of the human population and the earth. If it continues to rise with the amounts of carbon dioxide, the human population and the land we inhabit will be in trouble due to temperature and destruction. What can be attested to this rise of earth’s temperature is the burning of fossil fuels: coal, oil, and gas, that all release greenhouse gasses into the atmosphere. This has been studied heavily and due to the amounts of greenhouse gasses being pushed yearly, this is not normal or necessary. In a USA Today article reporting on the carbon dioxide emissions it states, “In the past 20 years, the world’s temperature has risen about two-thirds of a degree Fahrenheit,” which may not seem impactful, but this constant rising of temperatures will be detrimental without changes being made. Just hearing that global carbon dioxide emissions have reached the highest level in history, should be alarming and should incite awareness and sustainability ideas. To preserve the environment we live in and increase recycling, renewable energy sources, and reducing emission is crucial. As the world shifts back to a “normal society” after recovering from Covid-19, there needs to be a change from the Pre-Cvoid Era where human population abused the amount of fossil fuel use. There needs to be an alternative to burning coal in order to have factories, cars, and businesses be run. Coal has been the issue of 40% of the overall global carbon dioxide emissions in 2021. One idea we can look toward is electric car batteries and also the rise in use of solar panels.

The pandemic’s affect on Carbon Dioxide Emission

Posted on by

The pandemic brought forth by Covid-19 caused much change and hardship.  However, not every change that the world underwent in regards to the pandemic was bad.  Due to the decreased levels of travel that occurred from the pandemic, CO2 emissions fell by 5.4% in 2020.  In the United States alone, the 4.58 billion metric tons of carbon dioxide produced in 2020 was an 11% decrease from the previous year.  The decrease in the US was also due largely to the decrease in transportation seen both in the US and throughout the world.  Since the transportation sector is the biggest contributor to CO2 emissions in the US since 2016, this 11% decrease is a welcome change.   The drastically decreased amount of man-made pollution in the air appears as a positive from the outside.  However, despite the sudden 5.4% drop in CO2 emissions, the growth in atmospheric concentrations remained within the year to year variation caused by natural processes according to NASA.  This is due largely to the fact that absorb as much CO2 as it had in previous years.

The dip seen in reported levels of CO2 emissions was however temporary and the CO2 emission levels have bounced back up.  The 5.4% decrease reported during the early stages of the pandemic was still short of the necessary 7.6% yearly reduction estimated by the United Nations Environment Programme.  Even with the world at a standstill during the early months of the pandemic, the required decrease of CO2 emissions estimated to be necessary were still not met.  These decreased levels of CO2 have now rebounded due to the reopening of many sectors and the world is back on the same trajectory it had been on prior to the pandemic.
