Sector by sector: where do global greenhouse gas emissions come from?

  2023-10-06 (or before) in Our World in Data

Globally, we emit around 50 billion tonnes of greenhouse gases each year. Where do these emissions come from? We take a look, sector-by-sector.

Who has contributed most to global CO2 emissions?

  2023-10-04 (or before) in Our World in Data

There’s not only significant variability in how much CO2 countries emit across the world today. There are also large differences in how much each has emitted in the past. Who has contributed most to global CO2 since 1750?


Global primary energy consumption by source

  2023-07-30 (or before) in Our World in Data

Primary energy is calculated based on the 'substitution method' which takes account of the inefficiencies in fossil fuel production by converting non-fossil energy into the energy inputs required if they had the same conversion losses as fossil fuels.

Environmental Impacts of Food Production

  2023-04-16 (or before) in Our World in Data

What are the environmental impacts of food production? How do we reduce the impacts of agriculture on the environment?

Dairy vs. plant-based milk: what are the environmental impacts?

  2023-04-16 (or before) in Our World in Data

A growing number of people are interested in switching to plant-based alternatives to dairy. But are they better for the environment, and which is best?


Do we only have 60 harvests left?

  2022-12-30 (or before) in Our World in Data

Claims that the world has only 100, 60, or even 30 years of harvests left often hit the headlines. These claims are overblown, but soil erosion is a problem and we can do something about it.


If the world adopted a plant-based diet we would reduce global agricultural land use from 4 to 1 billion hectares

  2022-11-20 (or before) in Our World in Data

If everyone shifted to a plant-based diet we would reduce global land use for agriculture by 75%. This large reduction of agricultural land use would be possible thanks to a reduction in land used for grazing and a smaller need for land to grow crops.

Many countries have decoupled economic growth from CO₂ emissions, even if we take offshored production into account

  2022-08-05 (or before) in Our World in Data

Historically, CO2 emissions have been strongly correlated with how much money we have. This is particularly true at low-to-middle incomes. The richer we are, the more CO2 we emit. This is because we use more energy – which often comes from burning fossil fuels.

Income Inequality

  2022-03-14 (or before) in Our World in Data

How are incomes distributed and how and why did the distribution change over time?


Emissions from food alone could use up all of our budget for 1.5°C or 2°C – but we have a range of opportunities to avoid this

  2021-08-29 (or before) in Our World in Data

If we want to meet our global climate targets we need to reduce greenhouse gas emissions from food. What options do we have?

Nuclear Energy

  2021-04-13 (or before) in Our World in Data

As the world attempts to transition its energy systems away from fossil fuels towards low-carbon sources of energy, we have a range of energy options: renewable energy technologies such as hydropower, wind and solar, but also nuclear power. Nuclear energy and renewable technologies typically emit very little CO2 per unit of energy production, and are also much better than fossil fuels in limiting levels of local air pollution.

Global inequalities in CO‚ÇÇ emissions

  2020-05-07 (or before) in Our World in Data

There are two parameters that determine our collective carbon dioxide (CO2) emissions: the number of people, and quantity emitted per person. We either talk about total annual or per capita emissions. They tell very different stories and this often results in confrontation over who can really make an impact: rich countries with high per capita emissions, or those with a large population.


You want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local

  2020-01-25 (or before) in Our World in Data

‘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?

Energy

  2020-01-16 (or before) in Our World in Data

What energy sources does the world rely on? What is this energy used for? And how does it change over time?


World Population Growth

  2019-06-11 (or before) in Our World in Data

When and why did the world population grow? And how does rapid population growth come to an end?


CO‚ÇÇ and Greenhouse Gas Emissions

  2019-03-03 (or before) in Our World in Data

Who is emitting greenhouse gases? Which countries and which sectors? And what needs to happen to reduce emissions?
