This table contains the full text for all our old WORDPRESS content in html form. The format is a bit odd as it represents a direct copy from wordpress content that includes a lot of wordpress specific comments that carry some meaning in terms of layout instructions etc.. The html in the content column can thus be rendered as is but will not look identical to the way it looks on our website as several post processing steps are not applied yet. The content should work though as a readable approximation for every post. For easy searching etc, a markdown copy of the content is available in the markdown column. If you want to query all posts (both wordpress and gdocs), use the posts_unified table or the posts_unified_with_content view.

25082 Annual CO2 emissions untitled-reusable-block-34 wp_block publish <!-- wp:paragraph --> <p>Who emits the most CO<sub>2</sub> each year? In the treemap visualization we show annual CO<sub>2</sub> emissions by country, and aggregated by region. Treemaps are used to compare entities (such as countries or regions) in relation to others, and relative to the total. Here each inner rectangle represents a country – which are then nested and colored by region. The size of each rectangle corresponds to its annual CO<sub>2</sub> emissions in 2017. Combined, all rectangles represent the global total.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The emissions shown here relate to the country where CO<sub>2</sub> is produced (i.e.production-based CO<sub>2</sub>) , not to where the goods and services that generate emissions are finally consumed. We look at the difference in each country’s production vs. consumption (trade-adjusted) emissions <strong><a href="https://ourworldindata.org/grapher/production-vs-consumption-co2-emissions">here</a></strong>.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Asia is by far the largest emitter, accounting for 53% of global emissions. As it is <a href="https://ourworldindata.org/grapher/world-population-by-world-regions-post-1820?stackMode=relative">home to 60%</a> of the world’s population this means that per capita emissions in Asia are slightly lower than the world average, however.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>China is, by a significant margin, Asia’s and the world’s largest emitter: it emits nearly 10 billion tonnes each year, more than one-quarter of global emissions.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>North America – dominated by the USA – is the second largest regional emitter at 18% of global emissions. It’s followed closely by Europe with 17%. Here we have grouped the 28 countries of the European Union together, since they typically negotiate and <a href="https://climateactiontracker.org/countries/eu/">set targets</a> as a collective body. You can see the data for individual EU countries in the interactive maps which follow.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Africa and South America are both fairly small emitters: accounting for 3-4% of global emissions each. Both have emissions almost equal in size to international aviation and shipping. Both aviation and shipping are not included in national or regional emissions. This is because of disagreement over how emissions which cross country borders should be allocated: do they belong to the country of departure, or country of origin? How are connecting flights accounted for? The tensions in reaching international aviation and shipping deals are discussed in detail at the Carbon Brief <a href="https://www.carbonbrief.org/in-depth-will-countries-finally-agree-climate-deal-for-shipping"><strong>here</strong></a>.</p> <!-- /wp:paragraph --> <!-- wp:image {"id":25353} --> <figure class="wp-block-image"><img src="https://owid.cloud/app/uploads/2019/10/Annual-CO2-emissions-Treemap-1-603x550.png" alt="" class="wp-image-25353"/></figure> <!-- /wp:image --> <!-- wp:heading {"level":4} --> <h4>How did CO<sub>2</sub> emissions change over time?</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The same data is also explorable by country and over time in the interactive map.&nbsp;</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>By clicking on any country you can see how its annual emissions have changed, and compare it with other countries.</p> <!-- /wp:paragraph --> <!-- wp:html --> <iframe src="https://ourworldindata.org/grapher/annual-co2-emissions-per-country" style="width: 100%; height: 600px; border: 0px none;"></iframe> <!-- /wp:html --> <!-- wp:heading {"level":4} --> <h4>Share of global CO<sub>2</sub> emissions by country</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>In the interactive chart you can explore each country’s <em>share</em> of global emissions. Using the timeline at the bottom of the map, you can see how the global distribution has changed since 1751. By clicking on any country you can see its evolution and compare it with others.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>If you’re interested in which countries emit more or less than their ‘fair share’ based on their share of global population, you can explore this <a href="https://ourworldindata.org/share-co2-emissions"><strong>here</strong></a>.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The distribution of emissions has changed significantly over time. The UK was – until 1888, when it <a href="https://ourworldindata.org/grapher/annual-share-of-co2-emissions?tab=chart&amp;year=1890&amp;country=GBR+USA">was overtaken</a> by the US – the world’s largest emitter. This was because the UK was the first country to industrialize, a transition which later contributed to in massive improvements in living standards for much of its population.&nbsp;</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Whilst rising CO<sub>2</sub> emissions have clear negative environmental consequences, it is also true that they have historically been a by-product of positive improvements in human living conditions. But, it’s also true that reducing CO<sub>2</sub> emissions is important to protect the living conditions of future generations. This perspective – that we must consider both the environmental and human welfare implications of emissions – is important if we are to build a future that is both sustainable and provides high standards of living for everyone.&nbsp;</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Rising emissions and living standards in North America and Oceania followed soon after developments in the UK.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Many of the world’s largest emitters today are in Asia. However, Asia’s rapid rise in emissions has only occurred in very recent decades. This too has been a by-product of massive improvements in living standards: since 1950 life expectancy in Asia <a href="https://ourworldindata.org/grapher/life-expectancy?time=1770..2019&amp;country=Asia">has increased</a> from 41 to 74 years; it has seen a dramatic <a href="https://ourworldindata.org/grapher/share-of-the-population-living-in-extreme-poverty?tab=chart&amp;time=1981..2015&amp;country=East%20Asia%20%26%20Pacific+South%20Asia">fall in extreme poverty</a>; and for the first time most of its population <a href="https://ourworldindata.org/grapher/mean-years-of-schooling-long-run?tab=chart&amp;country=IND+CHN+BGD+JPN+KOR">received formal education</a>.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Whilst all countries must work collectively, action from the very top emitters will be essential. China, the USA and the 28 countries of the EU account for more than half of global emissions. Without commitment from these largest emitters, the world will not come close to meeting its global targets.</p> <!-- /wp:paragraph --> <!-- wp:html --> <iframe src="https://ourworldindata.org/grapher/annual-share-of-co2-emissions" style="width: 100%; height: 600px; border: 0px none;"></iframe> <!-- /wp:html -->

 Who emits the most CO2 each year? In the treemap visualization we show annual CO2 emissions by country, and aggregated by region. Treemaps are used to compare entities (such as countries or regions) in relation to others, and relative to the total. Here each inner rectangle represents a country – which are then nested and colored by region. The size of each rectangle corresponds to its annual CO2 emissions in 2017. Combined, all rectangles represent the global total. The emissions shown here relate to the country where CO2 is produced (i.e.production-based CO2) , not to where the goods and services that generate emissions are finally consumed. We look at the difference in each country’s production vs. consumption (trade-adjusted) emissions **[here](https://ourworldindata.org/grapher/production-vs-consumption-co2-emissions)**. Asia is by far the largest emitter, accounting for 53% of global emissions. As it is [home to 60%](https://ourworldindata.org/grapher/world-population-by-world-regions-post-1820?stackMode=relative) of the world’s population this means that per capita emissions in Asia are slightly lower than the world average, however. China is, by a significant margin, Asia’s and the world’s largest emitter: it emits nearly 10 billion tonnes each year, more than one-quarter of global emissions. North America – dominated by the USA – is the second largest regional emitter at 18% of global emissions. It’s followed closely by Europe with 17%. Here we have grouped the 28 countries of the European Union together, since they typically negotiate and [set targets](https://climateactiontracker.org/countries/eu/) as a collective body. You can see the data for individual EU countries in the interactive maps which follow. Africa and South America are both fairly small emitters: accounting for 3-4% of global emissions each. Both have emissions almost equal in size to international aviation and shipping. Both aviation and shipping are not included in national or regional emissions. This is because of disagreement over how emissions which cross country borders should be allocated: do they belong to the country of departure, or country of origin? How are connecting flights accounted for? The tensions in reaching international aviation and shipping deals are discussed in detail at the Carbon Brief [**here**](https://www.carbonbrief.org/in-depth-will-countries-finally-agree-climate-deal-for-shipping). <Image filename="Annual-CO2-emissions-Treemap-1.png" alt=""/> ## How did CO2 emissions change over time? The same data is also explorable by country and over time in the interactive map.  By clicking on any country you can see how its annual emissions have changed, and compare it with other countries. <Chart url="https://ourworldindata.org/grapher/annual-co2-emissions-per-country"/> ## Share of global CO2 emissions by country In the interactive chart you can explore each country’s _share_ of global emissions. Using the timeline at the bottom of the map, you can see how the global distribution has changed since 1751. By clicking on any country you can see its evolution and compare it with others. If you’re interested in which countries emit more or less than their ‘fair share’ based on their share of global population, you can explore this [**here**](https://ourworldindata.org/share-co2-emissions). The distribution of emissions has changed significantly over time. The UK was – until 1888, when it [was overtaken](https://ourworldindata.org/grapher/annual-share-of-co2-emissions?tab=chart&year=1890&country=GBR+USA) by the US – the world’s largest emitter. This was because the UK was the first country to industrialize, a transition which later contributed to in massive improvements in living standards for much of its population.  Whilst rising CO2 emissions have clear negative environmental consequences, it is also true that they have historically been a by-product of positive improvements in human living conditions. But, it’s also true that reducing CO2 emissions is important to protect the living conditions of future generations. This perspective – that we must consider both the environmental and human welfare implications of emissions – is important if we are to build a future that is both sustainable and provides high standards of living for everyone.  Rising emissions and living standards in North America and Oceania followed soon after developments in the UK. Many of the world’s largest emitters today are in Asia. However, Asia’s rapid rise in emissions has only occurred in very recent decades. This too has been a by-product of massive improvements in living standards: since 1950 life expectancy in Asia [has increased](https://ourworldindata.org/grapher/life-expectancy?time=1770..2019&country=Asia) from 41 to 74 years; it has seen a dramatic [fall in extreme poverty](https://ourworldindata.org/grapher/share-of-the-population-living-in-extreme-poverty?tab=chart&time=1981..2015&country=East%20Asia%20%26%20Pacific+South%20Asia); and for the first time most of its population [received formal education](https://ourworldindata.org/grapher/mean-years-of-schooling-long-run?tab=chart&country=IND+CHN+BGD+JPN+KOR). Whilst all countries must work collectively, action from the very top emitters will be essential. China, the USA and the 28 countries of the EU account for more than half of global emissions. Without commitment from these largest emitters, the world will not come close to meeting its global targets. <Chart url="https://ourworldindata.org/grapher/annual-share-of-co2-emissions"/>
