The World’s 25 Largest Lakes, Side by Side
The World’s 25 Largest Lakes, Side by Side
In many parts of the world, you don’t have to look very far to find a lake.
According to satellite data, there are roughly 100 million lakes larger than one hectare (2.47 acres) to be found globally. The largest lakes, which rival the size of entire nations, are more of a rarity.
One might expect the world’s largest lakes to be very alike, but from depth to saline content, their properties can be quite different. As well, the ranking of the world’s largest lakes is far from static, as human activity can turn a massive body of water into a desert within a single generation.
Today’s graphic – created using the fantastic online tool, Slap It On A Map! – uses the Great Lakes region as a point of comparison for the largest 25 lakes, by area. This is particularly useful in comparing the scale of lakes that are located in disparate parts of the globe.
The Greatest Lakes
The largest lake in the world by a long shot is the Caspian Sea – a name that hints at a past when it was contiguous with the ocean around 11 million years ago. This massive saline lake, which is nearly the same size as Japan, borders five countries: Kazakhstan, Russia, Turkmenistan, Azerbaijan, and Iran. An estimated 48 billion barrels of oil lay beneath the surface of the basin.
The five Great Lakes, which run along the Canada–U.S. border, form one of the largest collections of fresh water on Earth. This interconnected series of lakes represents around 20% of the world’s fresh water and the region supports over 100 million people, roughly equal to one-third of the Canada–U.S. population.
Amazingly, a single lake holds as much fresh water as all the Great Lakes combined – Lake Baikal. This rift lake in Siberia has a maximum depth of 5,371ft (1,637m). For comparison, the largest of the Great Lakes (Lake Superior) is only 25% as deep, with a maximum depth of 1,333ft (406m). Lake Baikal is unique in a number of other ways too. It is the world’s oldest, coldest lake, and around 80% of its animal species are endemic (not found anywhere else).
Here’s a full run-down of the top 25 lakes by area:

The Great Lakes World Tour
For people living in Canada and the U.S., the shape and relative size of the Great Lakes system may be quite familiar. This makes the Great Lakes a fantastic point of comparison to help put the size of other world locations into perspective. To this end, we begin our Great Lakes World Tour.
First, the image below shows how the Great Lakes system would look if it was located in India.
Distortions on commonly used maps can downplay the size of India compared to more northern nations. This view of the Great Lakes can help put India’s true size into perspective.
Next, we look at the Great Lakes overlaid within Central Europe.
In the context of Europe, the lakes are so large that they extend from the Netherlands over to Slovakia. Lake Superior’s surface area of 31,700 mi2 (82,000 km2), is similar in size to Austria. Here’s are the five Great Lakes and European countries of equivalent size:
Great Lakes | Surface Area | Equivalent Country | Area |
---|---|---|---|
Lake Superior | 82,000 km2 (31,700 sq mi) | 🇦🇹 Austria | 83,879 km2 (32,386 sq mi) |
Lake Huron | 60,000 km2 (23,000 sq mi) | 🇱🇻 Latvia | 64,589 km2 (24,938 sq mi) |
Lake Michigan | 58,000 km2 (22,300 sq mi) | 🇭🇷 Croatia | 56,594 km2 (21,851 sq mi) |
Lake Erie | 25,700 km2 (9,910 sq mi) | 🇲🇰 North Macedonia | 25,713 km2 (9,928 sq mi) |
Lake Ontario | 19,000 km2 (7,340 sq mi) | 🇸🇮 Slovenia | 20,271 km2 (7,827 sq mi) |
Lastly, here is a look at the Great Lakes in Southern Australia. Australia is the world’s 6th largest country, so the Great Lakes only occupy one corner of its land mass.
Australia’s lack of glacial history means that there are few permanent freshwater lakes in the country. Many of the country’s largest lakes only fill up during periods of excessive rainfall.
Shrinking out of the rankings
Not far from the world’s largest lake, straddling the border between Kazakhstan and Uzbekistan, lay the sand dunes of the Aralkum Desert. In the not so distant past, this harsh environment was actually the bed of one of the largest lakes in the world – the Aral Sea.
For reasons both climatic and anthropogenic, the Aral Sea began receding in the 1960s. This dramatic change in surface area took the Aral Sea from the fourth largest lake on Earth to not even ranking in the top 50. Researchers note that the size of the lake has fluctuated a lot over history, but through the lens of modern history these recent changes happened rapidly, leaving local economies devastated and former shoreside towns landlocked.
Lake Chad, in Saharan Africa, and Lake Urmia, in Iran, both face similar challenges, shrinking dramatically in recent decades.
How we work to reverse damage and avoid ecosystem collapse in vulnerable lakes will have a big influence on how the top 25 list may look in future years.

The Carbon Emissions of Gold Mining
Gold has a long history as a precious metal, but just how many carbon emissions does mining it contribute to?


The Carbon Emissions of Gold Mining
As companies progress towards net-zero goals, decarbonizing all sectors, including mining, has become a vital need.
Gold has a long history as a valuable metal due to its rarity, durability, and universal acceptance as a store of value. However, traditional gold mining is a process that is taxing on the environment and a major contributor to the increasing carbon emissions in our atmosphere.
The above infographic from our sponsor Nature’s Vault provides an overview of the global carbon footprint of gold mining.
The Price of Gold
To understand more about the carbon emissions that gold mining contributes to, we need to understand the different scopes that all emissions fall under.
In the mining industry, these are divided into three scopes.
- Scope 1: These include direct emissions from operations.
- Scope 2: These are indirect emissions from power generation.
- Scope 3: These cover all other indirect emissions.
With this in mind, let’s break down annual emissions in CO2e tonnes using data from the World Gold Council as of 2019. Note that total emissions are rounded to the nearest 1,000.
Scope | Type | CO2e tonnes |
---|---|---|
1 | Mining, milling, concentrating and smelting | 45,490,000 |
2 | Electricity | 54,914,000 |
3 | Suppliers, goods, and services | 25,118,000 |
1,2,3 | Recycled Gold | 4,200 |
3 | Jewelry | 828,000 |
3 | Investment | 4,500 |
3 | Electronics | 168 |
TOTAL | 126,359,000 |
Total annual emissions reach around 126,359,000 CO2e tonnes. To put this in perspective, that means that one year’s worth of gold mining is equivalent to burning nearly 300 million barrels of oil.
Gold in Nature’s Vault
A significant portion of gold’s downstream use is either for private investment or placed in banks. In other words, a large amount of gold is mined, milled, smelted, and transported only to be locked away again in a vault.
Nature’s Vault is decarbonizing the gold mining sector for both gold and impact investors by eliminating the most emission-intensive part of the mining process—mining itself.
By creating digital assets like the NaturesGold Token and the Pistol Lake NFT that monetize the preservation of gold in the ground, emissions and the environmental damage associated with gold mining are avoided.
How Does it Work?
Through the same forms of validation used in traditional mining by Canada’s National Instrument NI 43-101 and Australia’s Joint Ore Reserve Committee (JORC), Nature’s Vault first determines that there is gold in an ore body.
Then, using blockchain and asset fractionalization, the mineral rights and quantified in-ground gold associated with these mineral rights are tokenized.
This way, gold for investment can still be used without the emission-intensive process that goes into mining it. Therefore, these digital assets are an environmentally-friendly alternative to traditional gold investments.
