Carbon dioxide emissions are the primary driver of global climate change. It’s widely recognised that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless p...oint of contention in international discussions.
This debate arises from the various ways in which emissions are compared: as annual emissions by country; emissions per person; historical contributions; and whether they adjust for traded goods and services. These metrics can tell very different stories.
We teamed up with the YouTube channel, Kurzgesagt, to produce a video which explored these different metrics in detail: ‘Who is responsible for climate change? – Who needs to fix it?’. All of the data and research featured in this video is contained in this article: below we look in detail at the many ways emissions are broken down.

Both Ukraine and Russia are some of the world’s largest food exporters. How could global food be impacted?
Here you can download different charts about cases by world region, prevalence rates, and progress towards polio eradication and much more.
Polio is an infectious disease that is caused and transmitted by the poliovirus. Most infections do not lead to any symptoms, but—among the unvaccinated—...between 1 in 50 and 1 in 500 infections result in paralysis. For some it leads to death.
At the start of the 20th century, polio was endemic worldwide, with large epidemic outbreaks every year. But with the development of two vaccines in the 1950s, countries began eliminating polio one by one.

The Living Planet Index is the biodiversity metric that always claims the headlines. It’s often misinterpreted. How should we understand it?
High prevalence of target diseases in rural and developing nations, increased prevalence of malnutrition across the globe, lack of hygiene and poor sanitation facilities, Migratory patterns of population, introduction of new chemical entity in the field of therapeutics, favorable government regulati...ons, and increased R&D investments are key factors contributing to high CAGR of point of care diagnostics market during the forecast period.

The number of global reported natural disaster events in any given year. Note that this largely reflects increases in data reporting, and should notbe used to assess the total number of events.
Indoor air pollution is one of the world's largest environmental problems – particularly for the poorest in the world, who often do not have access to clean fuels for cooking.The Global Burden of Disease is a major global study on the causes and risk factors for death and disease. The study estima...tes of the annual number of deaths attributed to a wide range of risk factors are shown here. This chart is shown for the global total but can be explored for any country or region using the "change country or region" toggle.

Disease burden is measured in Disability-Adjusted Life Years (DALYs) – both from years of life lost due to premature death and years lived witha disability. One DALY equals one year of healthy life.
Estimated annual number of deaths from alcohol and drug use disorders per 100,000 people. These include only direct deaths from thesedisorders, meaning they do not include suicide deaths which can in some cases be connected or attributed to them.
Alcohol has historically, and continues to, hold an important role in social engagement and bonding for many. Social drinking or moderate alcohol consumption for many is pleasurable.
However, alcohol consumption – especially in excess – is linked to a number of negative outcomes: as a risk fa...ctor for diseases and health impacts, crime, road incidents, and, for some, alcohol dependence.
This topic page looks at the data on global patterns of alcohol consumption, patterns of drinking, beverage types, the prevalence of alcoholism, and consequences, including crime, mortality, and road incidents.

Estimated annual number of deaths from drug use disorders, by type of drug.
The article "Cardiovascular Diseases" on Our World in Data provides an in-depth analysis of cardiovascular diseases (CVD), the leading cause of death globally. It examines CVD trends, such as the decline in mortality rates in high-income countries d...ue to improved healthcare and lifestyle changes, while low- and middle-income countries experience rising CVD burdens. The article highlights major risk factors, including high blood pressure, obesity, smoking, and poor diet. It emphasizes the importance of preventive measures and access to treatment to reduce global disparities in CVD outcomes. The data-driven approach uses visualizations to illustrate the global impact and distribution of CVD.

The Our World in Data webpage on air pollution provides an extensive overview of the global impact of air pollution on health and the environment. It presents data on sources of pollution, such as i...ndustry, vehicles, and domestic energy use, and highlights the associated health risks, including respiratory and cardiovascular diseases. The site emphasizes that air pollution is one of the leading environmental risk factors for premature deaths worldwide, particularly affecting low- and middle-income countries. It also discusses trends in air pollution levels over time and the effectiveness of policy interventions in reducing pollution and improving public health.
