The Emissions Impact of Coronavirus Lockdowns
There’s a high chance you’re reading this while practicing social distancing, or while your corner of the world is under some type of advised or enforced lockdown.
While these are necessary measures to contain the spread of the COVID-19 pandemic, such economic interruption is unprecedented in many ways—resulting in some surprising side effects.
The Evidence is in NO₂ Emissions
Nitrogen dioxide (NO₂) emissions, a major air pollutant, are closely linked to factory output and vehicles operating on the road.
As both industry and transport come to a halt during this pandemic, NO₂ emissions can be a good indicator of global economic activity—and the changes are visible from space.
These images from the Centre for Research on Energy and Clean Air (CREA), as well as satellite footage from NASA and the European Space Agency (ESA), show a drastic decline in NO₂ emissions over recent months, particularly across Italy and China.
NO₂ Emissions Across Italy
In Italy, the number of active COVID-19 cases has surpassed China (including the death toll). Amid emergency actions to lock down the entire nation, everything from schools and shops, to restaurants and even some churches, are closed.
Italy is also an industrial hub, with the sector accounting for nearly 24% of GDP. With many Italians urged to work from home if possible, visible economic activity has dropped considerably.
This 10-day moving average animation (from January 1st—March 11th, 2020) of nitrogen dioxide emissions across Europe clearly demonstrates how the drop in Italy’s economic activity has impacted the environment.

That’s not all: a drop in boat traffic also means that Venice’s canals are clear for the time being, as small fish have begun inhabiting the waterways again. Experts are cautious to note that this does not necessarily mean the water quality is better.
NO₂ Emissions Across China
The emissions changes above China are possibly even more obvious to the eye. China is the world’s most important manufacturing hub and a significant contributor to greenhouse gases globally. But in the month following Lunar New Year (a week-long festival in early February), satellite imagery painted a different picture.

NO₂ emissions around the Hubei province, the original epicenter of the virus, steeply dropped as factories were forced to shutter their doors for the time being.
What’s more, there were measurable effects in the decline of other emission types from the drop in coal use during the same time, compared to years prior.
Back to the Status Quo?
In recent weeks, China has been able to flatten the curve of its total COVID-19 cases. As a result, the government is beginning to ease its restrictions—and it’s clear that social and economic activities are starting to pick back up in March.

With the regular chain of events beginning to resume, it remains to be seen whether NO₂ emissions will rebound right back to their pre-pandemic levels.
This bounce-back effect—which can sometimes reverse any overall drop in emissions—is [called] “revenge pollution”. And in China, it has precedent.

Vegetarianism: Tapping Into the Meatless Revolution
This graphic unearths the origins of the meatless revolution, while exploring how the $1.8 trillion meat market is responding to the threat of disruption.
Vegetarianism: Tapping into the Meatless Revolution
The way people choose and consume their food is changing, and it’s encouraging a sweeping shift from animal-based to plant-based food products.
Whether it’s from the perspective of environmental impact, cruelty to animals, or health benefits, meatless diets are quickly becoming a new normal for people around the world—but where did it all begin?
Today’s infographic unearths the origins of vegetarianism and explores how the industry erupted into a lucrative web of sub-categories that are whetting the appetite of investors the world over.
The Origins of the Meat-Free Diet
Taking a holistic view of vegetarianism, there are several different diets that people typically adhere to. A vegetarian for example, doesn’t eat meat but still consumes animal products such as dairy and eggs. On the other hand, a vegan eats a strictly plant-based diet.
With 70% of the global population now reducing their meat intake, veganism has become a lifestyle choice for many. By 2026, the global market is projected to be worth over $24 billion.
While this seems like a relatively new phenomenon, the meatless revolution has been quietly building for almost two centuries.
- 1847: The first vegetarian society is formed in England
- 1898: The world’s first vegetarian restaurant opens in Switzerland
- 1944: The term “vegan” is coined
- 1994: The first World Vegan Day is introduced
- 2014: Influential breakout documentary Cowspiracy is released
- 2017: 6% of the entire U.S. population claim to be vegan
- 2018: Roughly 8% of the global population claim to eat plant-based
- 2020: Acceptance of plant-based diets by both the medical community and general public is at an all-time high
Although vegetarian and vegan diets were once heavily stigmatized, global support is now growing.
Towards a Plant-Based Future
Today, people in dozens of countries are making big strides towards plant-based lifestyles.
China, for example, introduced guidelines to help its population of 1.3 billion people reduce their meat consumption by 50%. These ambitious goals will be driven by consumer’s growing understanding of the positive impacts of eating less meat, such as:
- Health benefits
According to the American Heart Association, reducing meat intake could reduce the risk of stroke, high blood pressure, type 2 diabetes, and even certain cancers.
- Environmental impact
Animal agriculture creates more greenhouse gases than the world’s entire transportation systems combined, but shifting to a plant-based diet could significantly reduce this problem.
- Animal welfare
Roughly two thirds of the 70 billion animals farmed annually are cramped in close quarters and given heavy medication. Plant-based diets eliminate animal suffering while lowering demand for other animal food products.
In fact, if more people commit to embracing a plant-based lifestyle, it could result in up to $31 trillion—or 13% of global GDP—in savings for the economy.
Big Players Fight For a Piece of the Pie
Given the newfound consumer demand for meat alternatives, it’s no surprise that global companies are clamouring to enter the market.
Many established food companies such as Nestlé and Danone are either advancing their own formula for plant-based proteins, or acquiring companies with existing experience.
Meanwhile, fast food chain McDonald’s features vegan products as permanent staple on their menu, and report an 80% uplift in customers buying these products in certain countries.
Big Meat Shifts Gears
As new players in the space attempt to cut into the $1.8 trillion global meat market, big meat companies are responding in kind.
Tycoons such as Tyson Foods and Cargill are placing bets on plant-based startups and filling shelves with their own plant-based products.
But while plant-based products created by traditional meat companies may appeal to less rigid flexitarians, vegans and vegetarians may not accept them so readily due to their strong ethics.
Food For Thought
Along with the uncertainty of how these products will be received, there are other challenges that the market must overcome in order to be considered truly accessible. For instance, plant-based alternatives boast higher price points than their predecessor’s products, which may deter consumers from entering en masse.
Regardless, it is clear that the shift to plant-based diets is a disruptive force that could change the food industry over the long term. Early movers are dangling a golden carrot in front of investors—but will they take a bite?
Visualizing the Human Impact on the Ocean Economy
The ocean economy is under threat. How are human activities impacting the sustainable use of our ocean assets, valued at over $24 trillion?
Visualizing the Human Impact on our Ocean Economy
When you think of economic output, it’s likely the ocean isn’t the first entity that comes to mind. But from facilitating international trade to regulating the climate, the “blue economy” contributes significant value in both tangible and intangible ways.
The sustainable use of the ocean and its resources for economic development and livelihoods have such far-reaching effects, that its protection is a significant goal of the United Nations, as well as for many other countries and organizations throughout the world.
However, these vital ocean assets are in danger of sinking quickly. Ahead of World Oceans Day on June 8, 2020, we look at the total value of assets that come from our ocean, and how various human activities are affecting these resources.
Global Ocean Asset Value
Economic value from all the oceans is measured both by their direct output, as well as any indirect impacts they produce.
According to the World Wildlife Fund, these combined assets are valued at over $24 trillion. Here’s how they break down:
- Direct Output: Marine fisheries, coral reefs, seagrass, and mangroves
Total value: $6.9T
Examples of direct output: Fishing, agriculture
- Trade and Transport: Shipping lanes
Total value: $5.2T
- Adjacent Assets: Productive coastline, carbon absorption
Total value: $7.8T, and $4.3T respectively
Examples of services enabled: Tourism, education/conservation (such as jobs created)
In fact, the annual gross marine product of the oceans is comparable to the Gross Domestic Product (GDP) of countries, coming in at $2.5 trillion per year—making it the world’s eighth largest economy in country terms.
Unfortunately, experts warn that various human activities are endangering these ocean assets and their reliant ecosystems.
The Cumulative Human Impact on Oceans
An 11-year long scientific study tracked the global effect of multiple human activities across diverse marine environments. The researchers identified four main categories of stressors between 2003-2013.
- Climate change: Sea surface temperature, ocean acidification, and sea level rise
- Ocean: Shipping
- Land-based: Nutrient pollution, organic chemical pollution, direct human pollution, light pollution
- Fishing: Commercial and artisanal fishing, including trawling methods
Across the board, climate stressors were the most dominant drivers of change in a majority of marine environments. Similarly, pollution levels have also increased for many ecosystems.
Plastic pollution is especially damaging, as it continues to grow at unprecedented rates, with a significant amount ending up in the oceans. The World Economic Forum estimates that by 2050, there could be more plastic in the ocean than fish by weight.
Among the various marine environments, coral reefs, seagrasses, and mangroves proved to be most at-risk, experiencing the fastest increase in cumulative human impact. However, these are also the same ecosystems that we rely on for their direct economic output.
Overall, climate-induced declines in ocean health could cost the global economy $428 billion annually by 2050.
The Ocean Economy is in Hot Water
It can be difficult to truly understand the scale at which we rely on the ocean for climate regulation. The ocean is a major “carbon sink”, absorbing nearly 30% of the carbon emitted by human activity. But acidity levels and rising sea surface temperatures are changing its chemistry, and reducing its ability to dissolve CO₂.
According to the UN, ocean acidification has grown by 26% since pre-industrial times. At our current rates, it could rise to 100-150% by the end of the century. Overfishing is another urgent threat that shows no signs of slowing down, with sustainable fish stocks declining from 90% to 66.9% in just over 40 years.
To try and counteract these issues, this year’s virtual World Oceans Day is focused on “Innovation for a Sustainable Oceans” to discuss various solutions, including how the private sector can work with communities to maintain the blue economy. In addition, there’s a petition in place to urge world leaders to help protect 30% of the natural world by 2030.
Will our human activities continue to stress the ocean economy, or will we be able to positively reverse these trends in the years to come?
