How are countries responding to the pandemic? When and what measures have countries put in place?

Data on the extent of testing for COVID-19 provides important information about the reliability of the data we use to understand the spread of the virus’. Here we discuss two measures of the extent testing and what they can tell us about the pandemic.

Our goal is to bring together the best data and build the visualization tools that allows you to understand the spread of the pandemic. Our free, open-access charts cover all countries in the world. Here we show how to customize and embed charts in your own articles.

We worked with the Youtube channel, Kurzgesagt, to make a video on the COVID-19 pandemic and what to do about it.

There are three main data sources on the latest Coronavirus outbreak (COVID-19). How do estimates of confirmed cases and deaths compare?

Food losses and waste – in supply chains and by consumers – account for around one-quarter of greenhouse gas emissions from food. That’s 6% of total global emissions.

How we treat the climate impacts of methane has a significant difference on the carbon footprint of foods. But even if we exclude methane, meat and dairy products have the highest footprint.

Fossil fuels are the dirtiest and most dangerous energy sources, while nuclear and modern renewable energy sources are vastly safer and cleaner. The differences are huge.

Despite large differences in farming practices across the world, plant-based protein sources still have a lower footprint than the lowest-impact meat products.

Adjusted for both population growth and aging, mortality from cancer is falling globally.

Transporting food by plane can come with a large carbon footprint. But very little of our food travels this way – just 0.16% of food miles are from air travel.

‘Eat local’ is a common recommendation to reduce the carbon footprint of your diet. But transport tends to account for a small share of greenhouse gas emissions. How does the impact of what you eat compare to where it’s come from?

The media claims we are experiencing a ‘loneliness epidemic’. What is the evidence for this?

In countries such as Denmark and Switzerland, it is very common for people to live alone; but contrary to what many believe, this does not translate into higher loneliness. Loneliness and aloneness are not the same.

One-person households are becoming increasingly common across the world. In this post we explore the data behind this trend.
