Pollution during Covid-19: What can we learn from this period?

Covid-19 has affected everyday life, but how has it affected pollution? We have heard good news that air pollution has gone down, but plastic waste seems to be making a comeback.

The only piece of good news that came out of Covid-19 seems to be the decrease in air pollution levels around the world. Most air pollution comes from the burning of fossil fuels from daily activities like driving cars and manufacturing items in factories, which with most of us staying home due to Covid-19, have decreased. The countries with the most polluted cities in the world – China and India – have seen massive drops in air pollution levels.

This is excellent news as 80% of people living in towns and cities are exposed to air pollution levels that are way above the healthy limit. According to the World Health Organization, many urban areas that are developing can have air pollution levels that are 4 to 15 times above WHO’s guidelines of the amount of Particulate Matter, or the particle pollution in the air, which stands at 10 micrograms per cubic meter for PM 2.5, and 20 micrograms per cubic meter for PM10. It is estimated that 7 million people die premature deaths every year due to air pollution.

However, it is expected that air pollution levels will go up again once the world goes back to business. As lockdown measures have lifted in China in the past month, reports are already emerging that China’s air pollution levels in April 2020 were higher than it was in April 2019. This pattern is expected to occur around the world as factories and businesses rush back to continue operations.

Air pollution is not the only concern during this time.

The amount of waste generated by single-use products during this time is increasing. As part of Singapore’s Circuit Breaker measures, it is now mandatory for us to wear masks when we leave our homes, and the masks have to be discarded after a single use. While the Singapore government has provided and encouraged us to use reusable masks, front-line workers have to use disposable surgical masks to protect themselves from the virus. A number of other equipment used by front line workers also has to be discarded after a single use. This is happening all around the world as COVID-19 continues to spread.

Single-use plastic is also making a comeback during this period due to safety and hygiene concerns. Most notably, Starbucks have banned the use of reusable tumblers and cups and will only sell beverages out of their single use cups out of safety concerns. Many states and stores in America have banned the use of reusable shopping bags, or temporarily suspended the laws that ban single-use plastic.
