Short-haul vs. long-haul; rich vs. poor countries: where do global CO2 emissions from aviation come from?
Aviation accounts for 2.5% of global CO2 emissions. How much from short vs. long-haul flights? How much from rich vs. poor countries?
Our World in Data
Aviation accounts for 2.5% of global CO₂ emissions.
Where do these emissions come from?
Most come from passenger flights. The richest half of the world account for 90% of emissions from air travel.

Climate change and flying: what share of global CO2 emissions come from aviation?
Flying is a highly controversial topic in climate debates. It accounts for around 2.5% of global CO2 emissions, but 3.5% when we take non-CO2 impacts on climate into account.

How much does aviation contribute to global climate change?
→ 2.5% of global CO₂ emissions
→ Non-CO₂ impacts mean it accounts for around 3.5% of warming today

Which form of transport has the smallest carbon footprint?
Transport accounts for almost one-quarter of global CO2 emissions. For individuals, it can be the largest part of their carbon footprint. But if you need to travel, what is the lowest-carbon way to do so? We take a look at the data.

Which form of transport has the lowest carbon footprint?
In our latest article we compare the emissions of different ways to travel.
For example, taking the Eurostar train from London to Paris reduces emissions by ~96% vs. taking a flight.

The Our World in Data COVID-19 Testing dataset has been published in the academic journal, Nature
Testing for COVID-19 is our window onto the pandemic and how it is spreading. Without data on who is infected by the virus, and how many people are dying from the infection, we have no way of understanding the pandemic. Without testing there is no...
Our World in Data
Since the early days of this pandemic we are building and maintaining the dataset on COVID-19 testing for countries around the world.
Now our dataset has been published in the academic journal @Nature Scientific Data.

The portal and database contain over 3 million data points and more than 100 indicators on COVID-19, updated daily.
Cars, planes, trains: where do CO2 emissions from transport come from?
Transport accounts for around one-fifth of global CO2 emissions. But where do these emissions come from, and how might they change in the coming decades?

Cars, planes, trains: where do CO₂ emissions from transport come from?
Three-quarters come from road transport.
But cars will be much easier to decarbonise than aviation, freight and ships.

Audience Survey – Who uses Our World in Data, and for what purpose?
Lately I’ve been using the analogy of a museum to describe Our World in Data. A museum offers its visitors a variety of experiences: you can book a guided tour and hear all the detailed stories behind the artworks, explore for yourself and wander...
Levelized cost of energy by technology
Levelized cost of energy (LCOE) estimates the average cost per unit of energy generated across the lifetime of a new power plant. It is measured in 2019 US$ per kilowatt-hour.
Per capita: tests for COVID-19 vs. Confirmed cases
Both measures are shown per million people of the country's population.
Living Planet Index by region
The Living Planet Index (LPI) provides a measure of biodiversity based on the average change in populations of species over time. The index value is measured relative to 20,811 populations of 4,392 species in 1970 (i.e. 1970 = 1).

We teamed up with Kurzgesagt to make a video about climate change: ‘Is It Too Late To Stop Climate Change? Well, it’s Complicated’
We teamed up with the YouTube channel, Kurzgesagt to make a video about climate change: its drivers and possible solutions.

We teamed up with our friends at @Kurz_Gesagt again to make a video about climate change.
It looks at the 4 factors driving CO₂ emissions, and how we can use these levers to find solutions.

When was homosexuality legalized?
Shown is when same-sex sexual acts stopped being considered a criminal offence. Some countries never contained a criminalising provision in their Penal Codes, while others consciously removed the criminalising provisions.
Military expenditure, constant 2015 US$
Figure illustrates military expenditure in constant 2015 US$. SIPRI's military expenditure aims to include all spending on current military forces and activities. See the source tab for further information on its definition.
It’s not just about child mortality, life expectancy improved at all ages
It’s often argued that life expectancy across the world has only increased because child mortality has fallen. But this untrue. The data shows that life expectancy has increased at all ages.
