France generates two-thirds of its electricity from nuclear power. As the chart shows, that’s far more than the global average, just under 10%. Even though its share in France has declined slightly in recent years, it’s still its dominant power source.
Nuclear power is a low-carbon electricity source, allowing France to have a very clean electricity mix for decades.
Per unit of electricity, France emits far less carbon dioxide (CO2) than its neighbors and has some of the lowest-carbon power in the world. The global average is 438 grams of CO2 per kilowatt-hour of electricity generated. In France, this figure is 85 grams.

The United States is the world’s largest oil producer.
The chart shows annual production by country from 1990 to 2023. The US has been the largest producer for the last seven years.
Production in the US gradually declined during the 1990s and early 2000s but increased steeply again post-2010 and is now at an all-time high.
This data comes from the Energy Institute’s Statistical Review of World Energy.

European neighbors Portugal and Spain are currently neck-and-neck in the race to roll out solar and wind power.
On the chart, you can see the share of electricity from the combination of solar and wind in each country. Their rate of progress has been very similar.
In 2023, both countries generated around 40% of their electricity from these sources. Wind power is more prevalent in Portugal, while solar is more used in Spain.
This data comes from Ember.

There are two key drivers of sea level rise. First, water expands as it gets warmer. Second, ice on land — in the form of ice sheets and glaciers — melts and adds water to ocean basins.
Both of these processes have accelerated due to climate change. The effect is shown in the chart, based on data from the US’s National Oceanic and Atmospheric Administration. It combines two sources: recent data from the University of Hawaii Sea Level Center and a publication from Church and White (2011).
On this chart, the rise in sea level is measured relative to the average from 1993 to 2008. Levels had risen by almost 20 centimeters between 1880 and this period, and 5 more centimeters since. Combined, that’s around 25 centimeters.

Food miles — moving products from farms to processors to consumers — contribute just 5% to 6% of the greenhouse gas emissions from food. Instead, most emissions come from land use change or emissions on the farm.
Within food miles, people often assume that international freight accounts for most of the climate impact. In reality, most of these emissions come from domestic delivery trucks on the road.
In the chart, you can see the breakdown of transport’s 5% of food emissions. Road transport represents 3.9%, compared to just 0.02% from aviation. This is based on data from a 2021 study by researchers M. Crippa and colleagues.
International food miles are just a small share of emissions because very little food is flown by air, and transporting goods by boat is much more carbon-efficient than by road.

Today, there are around 830 million people aged 65 and older in the world. According to the latest UN data, it is projected to grow to 1.7 billion by 2054.
Asia, the world's most populous continent, is at the heart of this change, with its elderly population expected to more than double.
While rapid population growth has driven some of this increase, better healthcare and longer life spans also play a huge role.
It’s a great achievement that so many more people are living longer, healthier lives. At the same time, the working-age population will only grow 20% between 2024 and 2054. Societies will need to figure out how to care for more elderly people while improving everyone’s quality of life.

Around 40% of the world’s plastic waste comes from packaging. Packaging also makes up a significant share in the three regions that generate the most plastic waste: the United States, Europe, and China.
Packaging accounts for 37% of total plastic waste in the United States. It’s 38% in Europe, and in China, it's 45%. Together, these regions account for 60% of global packaging waste generation. This data comes from the OECD Global Plastics Outlook.
These figures show the vast impact of packaging on global plastic waste.

At the turn of the millennium, Australia got more than 80% of its electricity from coal. This has dropped to less than 50%.
The chart shows how the country’s electricity mix has changed in recent decades. The data comes from the Energy Institute’s Statistical Review of World Energy.
In the 2000s and early 2010s, coal was initially replaced by gas, with only moderate growth in solar and wind. But in the last five years, solar and wind have been deployed much more quickly. Gas is now on the decline, too. In 2023, solar overtook gas to become Australia’s second-largest electricity source.
While coal is declining, it still supplies much more of Australia’s power than most high-income countries.
