Nitrogen dioxide emissions decreased by 30% in some areas of China
Nitrogen dioxide (NO2) is a highly toxic pollutant generated by cars and other combustion engines. In an article published in the Science of the Total Environment, the authors examined the relationship between long-term exposure to nitrogen dioxide and coronavirus mortality. The results showed that 78% of deaths due to COVID-19 occurred in areas with the highest NO2 concentrations. Northern Italy, one of the regions hardest hit by the pandemic, exhibited high levels of NO2 and PM2.5, which are harmful particulates.
Satellite images revealed that nitrogen dioxide emissions in some areas of China decreased by 30%. This decrease in emissions can be attributed to country-wide investments in wind and solar energy. China has been at the forefront of renewable energy, with more than half of the solar and wind generation capacity installed globally in recent years being attributed to the country. In April 2025, wind and solar energy sources generated more than a quarter of China's electricity for the first time. This shift towards renewable energy sources has led to a decline in the use of fossil fuels, with electricity generated from these sources falling by 3.6% in the first four months of 2025 compared to the previous year.
While China's efforts to reduce emissions are commendable, it is important to note that the country is still responsible for approximately 30% of global emissions. However, the recent decline in emissions is significant, especially considering that previous drops have only occurred during economic shocks, such as the COVID-19 pandemic. The pandemic may have inadvertently contributed to the decrease in emissions, as it slowed down economic activity and reduced industrial operations.
Despite the positive impact on emissions, the pandemic has also had negative consequences for the environment. In the United States, for example, the Environmental Protection Agency (EPA) suspended requirements for companies to comply with environmental laws during the pandemic. Additionally, the administration rolled back emissions standards, hindering efforts to combat climate change. The focus on economic recovery may also lead governments to loosen environmental regulations, potentially undoing the gains made during the pandemic.
It is crucial to address the complex relationship between the pandemic and environmental factors. While emissions may have decreased in some regions due to reduced economic activity, the suspension of environmental regulations could offset these gains. The COVID-19 pandemic has highlighted the urgent need to transition to cleaner energy sources and implement sustainable practices to protect public health and the environment.

Air pollution can increase COVID-19 deaths
The COVID-19 pandemic has had a positive impact on the environment, with many countries experiencing improved air quality due to reduced economic activity and travel. However, the relationship between air pollution and COVID-19 mortality is complex and has been the subject of extensive scientific study.
Several studies have found a correlation between long-term exposure to air pollution and increased COVID-19 mortality rates. Research suggests that air pollution can increase the risk of dying from COVID-19 by up to 15% worldwide. For example, a study in the Netherlands found that a small increase in pollution exposure was associated with a 21% rise in the COVID-19 death rate. Similarly, a study by Francesca Dominici, director of the Harvard Data Science Initiative, showed that a small increase in long-term exposure to fine dust resulted in an increase in the COVID-19 mortality rate by up to 8%.
The link between air pollution and COVID-19 mortality is particularly strong in areas with high concentrations of pollutants, such as nitrogen dioxide (NO2) and fine particulate matter (PM2.5). These pollutants are known to cause breathing difficulties and other long-term respiratory and cardiovascular conditions, which can exacerbate the severity of COVID-19 symptoms. In England, 35% of COVID-19 deaths up to the end of June 2020 had a respiratory or cardiovascular disease as the main pre-existing health condition.
Additionally, the COVID-19 pandemic has disproportionately affected people of Black, Asian and Minority Ethnicities (BAME), who are more likely to live in inner-city areas with higher pollution levels. While the data is inconclusive, one study suggested that long-term exposure to PM2.5 could increase the risk of dying from COVID-19 by up to 7% for the BAME population.
Overall, while the coronavirus pandemic may have led to a temporary improvement in air quality in some regions, air pollution remains a significant factor contributing to the severity and mortality rates of COVID-19.

Lockdowns and quarantining reduce human activity and improve air quality
Lockdowns and quarantining have significantly reduced human activity, leading to notable improvements in air quality. NASA and the European Space Agency (ESA) satellites recorded a significant drop in pollution levels from January to February, specifically noting a decrease in nitrogen dioxide emissions. This reduction in nitrogen dioxide is directly linked to decreased traffic, as cars are a significant contributor to this pollutant, along with power plants and industrial sites. The decrease in air pollution may have even saved more lives than the coronavirus death toll, particularly among children under five, as per Stanford University scientist Marshall Burke's calculations.
The impact of lockdowns and quarantining on air quality was particularly evident in China, where satellite images showed a 30% decrease in nitrogen dioxide emissions in certain areas during the initial months of the pandemic. However, it is important to note that these gains may be temporary, as new data from April indicated slightly higher levels of nitrogen dioxide and fine dust in the same regions compared to the previous year.
The coronavirus pandemic has also led to a decrease in driving and flying, with notable improvements in air quality observed in various parts of the world. For instance, the canals in Venice were reported to be cleaner, and people in certain areas of India could see the Himalayan peaks for the first time in years due to reduced air pollution.
While the pandemic has resulted in a temporary improvement in air quality, it has also highlighted the trade-offs between economic growth and environmental progress. The economic slowdown associated with the pandemic has had devastating consequences for many industries, and governments may prioritize economic recovery over environmental regulations. Additionally, the pandemic has revealed the importance of balancing environmental progress with the ability to earn a living and access basic necessities, such as affordable and reliable electricity.
Overall, the lockdowns and quarantining measures implemented during the coronavirus pandemic have undoubtedly reduced human activity and improved air quality in the short term. However, the long-term impact on pollution remains uncertain, and the trade-offs between economic growth and environmental progress are complex and multifaceted.

Governments may loosen environmental regulations to boost economies
The COVID-19 pandemic has had a devastating impact on economies worldwide. In response, governments may loosen environmental regulations to stimulate economic growth. While this approach may provide short-term economic benefits, it could also have adverse effects on the environment and public health.
The relationship between environmental regulations and economic competitiveness is complex. Environmental regulations can impact firms' competitiveness through trade, industry location, employment, productivity, and innovation. Early studies on the impact of environmental regulations found measurable but not severe effects on the overall national economy. For example, while price increases due to regulatory requirements can be significant, they may be offset by investments in pollution abatement.
However, environmental regulations can also lead to adverse effects on trade, employment, plant location, and productivity, particularly in pollution- and energy-intensive sectors. Environmental policies can affect firms' long-term competitiveness by altering their investment decisions. For instance, investment in pollution control can divert resources away from production, potentially hampering productivity growth.
During the COVID-19 pandemic, some governments have relaxed environmental regulations to support economic recovery. For instance, in the United States, the EPA suspended requirements for companies to comply with certain environmental laws during the pandemic and rolled back emissions standards. Additionally, the congressional bailout deal favored fuel-inefficient industries while neglecting the growing renewable energy sector.
While loosening environmental regulations may provide short-term economic relief, it could also have negative consequences for the environment and public health. It is essential to consider the potential trade-offs between economic growth and environmental sustainability when making policy decisions.

The cost-benefit of environmental regulation is questioned
The COVID-19 pandemic has had a notable impact on the environment, with human activity decreasing significantly as lockdowns and travel restrictions were imposed worldwide. Satellite images from NASA and the European Space Agency (ESA) observed a significant reduction in pollution levels from January to February, specifically a decrease in nitrogen dioxide emissions, which are directly linked to the use of cars, power plants, and industrial sites. This environmental respite, however, comes at a devastating human cost, with the pandemic causing immense physical and financial suffering.
While the environmental benefits of the pandemic are evident, the question arises: is it worth it? The cost-benefit analysis of environmental regulation becomes crucial. The pandemic has forced a grand experiment upon humanity, revealing the intricate connection between economic activity and environmental consequences. The trade-off between economic growth and environmental progress is not always favourable, as seen in the United States, where higher prices for stricter environmental standards have yielded negligible environmental gains.
Moreover, the pandemic has highlighted the urgency of addressing the climate crisis. Experts argue that the rapid behavioural changes during the pandemic demonstrate our capacity to act on climate change. The dramatic decrease in greenhouse gas emissions from the transport and industry sectors underscores the potential for significant reductions with collective action. This realisation should propel us to harness human ingenuity to rebuild our economies in a more sustainable and environmentally harmonious manner.
The relationship between air pollution and COVID-19 mortality rates is another critical aspect. Studies indicate a strong link between long-term exposure to air pollution, particularly nitrogen dioxide (NO2), and increased COVID-19 deaths. In Northern Italy, for example, high NO2 concentrations were correlated with 78% of COVID-19 deaths. This knowledge underscores the importance of environmental regulation to safeguard public health and mitigate the impact of future pandemics.
In conclusion, while the COVID-19 pandemic has temporarily improved the environment, the cost-benefit analysis of environmental regulation remains complex. The pandemic has underscored the need to address the climate crisis, highlighted the potential for collective action, and emphasised the critical role of environmental regulation in protecting public health. Moving forward, we must strive to balance economic growth with environmental sustainability, harnessing our newfound awareness to create a healthier future for all.
