Water is the world’s most vital resource. Beyond its basic functions of sustaining life, it’s also a precious commodity – one that billions of people in the world have trouble accessing.

Today’s infographic is from Raconteur, and it puts the global issue of water access into staggering perspective. It’s a two-fold problem: safe drinking water is hard to come by, while basic access to sanitation is less common than you’d expect.

Diving into Drinking Water

It’s easy to take water for granted when it comes out of every tap in developed economies, but the stark reality is that 2.1 billion people worldwide can’t get safe water this way.

Many people in the world spend hours waiting in long lines, often multiple times a day, for community-shared water, or, they have to travel to distant sources just to collect it.

World regions are categorized according to five classifications for drinking water access.

Here’s a breakdown of how each region fares.

The water crisis in Flint, Michigan is a dire exception to the safely managed water rule in North America. After a change in river source in 2014, insufficient water treatment resulted in lead from pipes leaching into the drinking water, affecting over 100,000 residents.

The Struggle of Sanitation

managed sanitation classifications

The invention of the toilet in 1875 is credited with saving one billion lives to date. Yet, poor water hygiene and its associated diseases claim the lives of roughly one million people annually.

This is because roughly 4.5 billion people still don’t have access to a toilet, with the problem being particularly acute on the African continent. More than half of the population in Eritrea (76%), Niger (71%), Chad (68%) and South Sudan (61%), for example, do not have any access to even basic sanitation.

Every Drop of Water Counts

According to the World Economic Forum, water has been a top-five global risk for the past seven years.

From an economic perspective, it’s easy to see why:

  • An estimated $260 billion is lost globally each year from the lack of basic water and sanitation.
  • Almost $18.5 billion in benefits can come from universal access to basic water and sanitation.

Securing water access has profound consequences. For every $1 invested in water and sanitation, there’s a $4 return from lower health costs, higher productivity, and fewer preventable deaths.

Fortunately, progress is being made on the global scale. Between 2001 and 2015, there’s been a 9% improvement in safe drinking water, while safely managed sanitation has risen by 10%.

The Biggest Carbon Emitters, By Sector

The manufacturing and construction sector contributed to 6.3 billion tonnes of global greenhouse gas emissions in 2019.

The Biggest Carbon Emitters, By Sector

It’s no secret that greenhouse gas emissions need to decrease drastically in order to fight the effects of climate change.

As countries across the globe ramp up efforts to reduce global warming, every industry needs to do its part. So who’s lagging and who’s leading?

Although often less discussed, the manufacturing and construction sector is a large contributor to global greenhouse gas emissions.

The above graphic from Northstar Clean Technologies takes a look at the biggest contributors by sector in relation to greenhouse gas emissions.

Breakdown Of Emissions

The manufacturing and construction sector is a growing one, and as population and infrastructure expand, it’s vital that we take all actionable paths to reduce emissions.

Manufacturing and construction contributed to 6.3 billion tonnes of global greenhouse gas emissions in 2019. Let’s look at the breakdown of greenhouse gas emissions by sector over the years from Our World In Data.

In 2019 electricity and heat were the biggest carbon emitters, while transport came in second place.

Manufacturing and construction overtook the agriculture sector in 2007 to become the third largest contributor to global greenhouse gas emissions.

Building a Solution

One solution to reducing the impact of the manufacturing and construction sector is to repurpose materials. This reduces emissions and waste while also being both energy and cost-efficient.

Take a material like asphalt shingles as an example. This product is found on the roofs of approximately 75% of single-family detached homes in the U.S. and Canada.

In 2018, 86% of total asphalt shingles waste was dumped in landfills where they do not decompose or biodegrade. Reusing and recycling existing materials like asphalt shingles is a vital step in reducing greenhouse gas emissions in the industry.

Northstar Clean Technologies repurposes the three primary components of asphalt shingles which are then recycled back into the market.

By reprocessing asphalt shingles into three primary components, Northstar’s clean technology has been shown to reduce CO₂ emissions by 60% compared to virgin production of liquid asphalt.

Mapped: Carbon Dioxide Emissions Around the World

This graphic maps out carbon emissions around the world and where they come from, using data from the European Commission.

Mapped: Carbon Dioxide Emissions Around the World

According to Our World in Data, the global population emits about 34 billion tonnes of carbon dioxide (CO₂) each year.

Where does all this CO₂ come from? This graphic by Adam Symington maps out carbon emissions around the world, using 2018 data from the European Commission that tracks tonnes of CO₂ per 0.1 degree grid (roughly 11 square kilometers).

This type of visualization allows us to clearly see not just population centers, but flight paths, shipping lanes, and high production areas. Let’s take a closer look at some of these concentrated (and brightly lit) regions on the map.

China, India, and the Indian Ocean

As the two most populated countries and economic forces, China and India are both significant emitters of CO₂. China in particular accounts for about 27% of global CO₂ emissions.

And looking at the oceans, we see how much shipping adds to emissions, with many shipping lanes east of China clearly outlined as well as the major Indian Ocean lane between the Strait of Malacca and the Suez Canal.

The United States and Central America

The United States is one of the world’s biggest carbon emitters. While other countries like Qatar and Saudi Arabia technically have higher emissions per capita, their overall emissions are relatively low due to smaller populations.

Across the U.S., the most brightly lit areas are major population centers like the Boston-Washington corridor, the Bay Area, and the Great Lakes. But also lit up are many of the interconnecting highways linking all these population centers, even in the less-populated middle of the country.

With so much traffic in and out of the U.S., the oceans become a murky mix of shipping and flight paths. To the south, very clearly visible is the major concentration of people around Mexico City and the traffic flowing through the Panama Canal.

South America’s Network of Emissions

Like the other regions, some of South America’s most populated areas are also the biggest emitters, such as São Paulo and Rio in Brazil and Buenos Aires in Argentina. This map also highlights the continent’s rough terrain, with most of the population and highway emissions limited to the coasts.

However, the cities aren’t the only big emitters in the region. There are clear lines intersecting the Amazon forest in many sections where cities and roads were constructed, including the economic hub city of Manaus along the Amazon River. Likewise, the oceans have many major shipping lanes highlighted, particularly East of Brazil.

Europe and North Africa

Germany is one of Europe’s biggest carbon emitters—in 2021, the country generated almost 644 million tonnes of CO₂.

Also making an impression are Italy (which is the second-highest CO₂ emitter after Germany) and the UK, as well the significant amount of trade along the English Channel.

Compared to the intricate network of cities, towns, and bustling highways spanning Europe, across the Mediterranean are far clearer and simpler lines of activity in Northern Africa. Two major exceptions are in the Middle-East, where Egypt’s Nile River and Suez Canal are massively lit up, as well as Israel on the east of the sea.

But a more significant (albeit murkier) picture is drawn by the massive amounts of shipping and flight paths illuminating the Atlantic and Mediterranean at large.

Net Zero by 2050

To mitigate the negative effects of climate change, countries around the world have made commitments to reach net-zero emissions.

Imagining the global map of emissions with these commitments in action requires a complete transformation of energy production, consumption habits, transportation infrastructure, and more. And even then, a future generated map wouldn’t be fully dark, as “net-zero” is not equivalent to zero emissions but a balance of emissions and removal.

How might this map of global emissions look in the near and distant future? And what other interesting insights can you generate by browsing the world this way?
