Yellow text that says Nuclear Weapons by Our World in DataNuclear WeaponsHow many states have nuclear weapons, and how many warheads do they have? How is this changing over time? Explore research and data on nuclear weapons.EnergyExplore our data and research on global energy.A dark blue background with a lighter blue world map superimposed over it. Yellow text that says CO2 and Greenhouse Gas Emissions by Our World in DataCO₂ and Greenhouse Gas EmissionsHuman emissions of greenhouse gases are the primary driver of climate change. The world needs to decarbonize to reduce them.ThumbnailPer capita, national, historical: how do countries compare on CO2 metrics?There are many ways to measure countries’ contributions to climate change. What do they tell us?ThumbnailAnimal WelfareSee all our data, visualizations, and writing on animal welfare.ThumbnailDiet CompositionsExplore data on diet compositions.Food PricesFood needs to be affordable for people, and at the same it is a key source of income for one-quarter of the world’s labor force.Hunger and UndernourishmentWhat are the consequences of undernourishment and how can we make progress against hunger and undernourishment?Agricultural ProductionHow much, and what types of food, do countries produce across the world?ThumbnailNatural DisastersHow many people die from disasters, and how are these impacts changing over time?A dark blue background with a lighter blue world map superimposed over it. Yellow text that says Environmental Impacts of Food Production by Our World in DataEnvironmental Impacts of Food ProductionWhat are the environmental impacts of food production? How do we reduce the impacts of agriculture on the environment?FertilizersFertilizers supply plants with nutrients that are essential for growth.A dark blue background with a lighter blue world map superimposed over it. Yellow text that says Crop Yields by Our World in DataCrop YieldsIncreasing crop yields is crucial to improve food security, living standards, and reduce human impacts on the environment.Which countries have put a price on carbon?Putting a price on carbon helps us account for the real costs of fossil fuels in the market. Which countries have a carbon tax or trading system?PesticidesPesticides are used to protect plants from weeds, fungi, or insects. Where are they used? What is their impact?The wordmark for Our World In DataWhat’s the difference between direct and substituted primary energy?How do different metrics of energy quantification compare?Missing data on energy: our list of datasets that are needed but are not availableWhat are the key datasets on global energy that the world needs, but are not publicly available?Renewable EnergyRenewable energy sources are growing quickly and will play a vital role in tackling climate change.Electricity MixExplore data on where our electricity comes from and how this is changing.Nuclear EnergyExplore global data on nuclear energy production and the safety of nuclear technologies.Energy MixExplore global data on where our energy comes from, and how this is changing.Energy Production and ConsumptionExplore data on how energy production and use varies across the world.ThumbnailCO₂ emissions by fuelCoal, oil, gas or flaring: where do our CO₂ emissions come from? How are emissions from these fuels changing over time?ThumbnailGreenhouse gas emissionsWhich countries emit the most greenhouse gases each year? How do they compare per person?ThumbnailBreakdown of carbon dioxide, methane and nitrous oxide emissions by sectorHow much does electricity, transport and land use contribute to different greenhouse gas emissions?A dark blue background with a lighter blue world map superimposed over it. Yellow text that says Meat and Dairy Production by Our World in DataMeat and Dairy ProductionMeat is an important source of nutrition for people around the world. How quickly is demand growing? And what are the implications for animal welfare and the earth’s environment?Access to EnergyAccess to electricity and clean cooking fuels are vital for a good standard of living and good health.Fossil fuelsFossil fuels were key to industrialization and rising prosperity, but their impact on health and the climate means that we should transition away from them.A dark blue background with a lighter blue world map superimposed over it.
