G20 Per Capita Coal Power Emissions 2023

More countries are seeing decreasing per capita coal emissions as they shift towards clean power, but coal pollution remains an issue.

New analysis by energy think tank Ember finds that per capita coal power pollution in more than half of the G20 economies are declining. However, despite continued decline, the top two coal polluters — Australia and South Korea — are still far ahead; a position they have held since 2020.

This showcases the pace of clean transition, which is one of the key drivers to phase down coal, is not fast enough. Coal reliance continues in the group’s major economies, increasing in countries such as China which falls in third place for per capita coal emissions.

The G20 could make or break global efforts to accelerate clean power.

The G20 has become a focal point for global efforts to advance clean power transition and reduce carbon emissions. Accounting for 85% of the global GDP and contributing to 80% of the world’s power sector emissions, the G20 plays a crucial role to lead this transition.

Around 36% of global electricity was generated from coal in 2022, producing 8,367 million tonnes of carbon emissions. Calculated on a per capita basis, this means that the average person worldwide emitted around 1.1 tonnes of carbon dioxide from coal power in 2022. 

In addition to comparing countries on their share of coal power and total power sector emissions, it is a helpful metric to consider emissions on a per capita basis to compensate for large differences in population size and electricity demand.

Ember data shows that G20 countries (excluding the EU as a region) emit 1.6 tonnes of coal power emissions per capita, exceeding the world average of 1.1 tonnes of carbon dioxide.

Yet the G20 countries remain divided in their deliberations on the call to triple renewables and have failed to come to a consensus.

Amid controversies, 75 nations are showing commitment by either phasing out coal or not building new coal plants without carbon capture. However, challenges remain, as seven G20 nations—Brazil, China, India, Japan, South Korea, South Africa, and the United States—haven’t yet unveiled their coal phase-down strategies.

Highlighted by an increasingly extreme climate, the urgency to ensure a global temperature rise well below 1.5C is clearer than ever. As the world’s major economies and top carbon emitters, decisions the G20 states make on clean transition will have lasting implications. And wider acceleration of renewables within the G20 will help drive this.

Each of the top two polluters emit more than triple the 2022 global average, highlighting the urgency for faster clean transition.

In 2022, per capita emissions from coal power in all G20 countries combined was 1.6  tonnes of carbon dioxide. This is 54% more than the global average in the rest of the world which stood at 1.1 tonnes of carbon dioxide.

Australia and South Korea particularly stood out as the top two coal polluters per-capita among the G20, an unchanged status since 2020. They each emit over three times the global average and more than twice the G20 average, surpassing even China, the US, and Japan.

Australia remained the highest in terms of per capita coal power emissions of all G20 countries despite recent uptick in wind and solar power. Australia has twice the electricity use per capita of China, and still 47% of its electricity in 2022 was from coal power. However, solar and wind power have been growing: their share of electricity rose from 7% in 2015 to almost 26% in 2022, which was the main reason for the fall in share of coal from 64% to 48%. At the same time, electricity use per capita was broadly unchanged. This means per capita coal power emissions fell by 26% from 2015 to 2022. 

In 2022, coal power emissions per capita fell by about 5%, compared to 2021, as coal generation fell by 8 TWh. This was caused by a rise in solar, wind and gas generation, even as electricity demand rose by more than 2%.

In South Korea, the  share of wind and solar was only 1% of electricity in 2015, and it has grown fivefold since then to more than 5% in 2022. Yet South Korea’s solar and wind share is still well below the global average of 12%, and their electricity is still 34% powered by coal. This has led them to emit more than three metric tonnes of carbon dioxide per individual, which also amounts to approximately three times the global average. This is despite their per capita coal emissions having dropped by 10% in seven years between 2015 to 2022.

The combined G20 per capita emissions barely changed since 2015.

Growing wind and solar are helping to reduce coal power emissions per capita in many countries, but it’s not enough yet to keep pace with rising electricity demand in most emerging countries. The G20 per capita emissions have shown minimal change since 2015.

Trends in coal power emissions per capita in G20 countries, 2015-2022

Global coal power emissions per capita have increased slightly from 1 tonnes of carbon dioxide in 2015 to 1.1 tonnes of carbon dioxide in 2022. However, at a national level in the G20, there has been a decline in the majority of countries, with some emerging economies continuing to see increases in coal power emissions per capita.

Twelve G20 economies seeing declines in emissions per capita

Per capita coal power emissions have decreased in major G20 economies in the last seven years, including in Australia, South Korea, South Africa, the US, Germany, Canada, the UK, Brazil, Mexico, France, Italy and Argentina.

The UK saw the most significant decline in coal power emissions per capita in the last seven years, dropping by 93%, followed by France (-63%), Italy (-50%), and Brazil (-42%). In both France and Brazil, the declines resulted from fossil generation being replaced by cleaner sources.

In Australia, coal power emissions per capita have dropped by 26% since 2015, driven by the massive growth in solar and wind. South Korea’s emissions have also decreased, though not as fast. With increasing clean power generation, South Korea has seen a 10% drop in coal power emissions per capita between 2015 and 2022.

However, despite these noteworthy declines in Australia and South Korea, their coal power emissions per capita remain much higher than the world average.

Among the G20, per capita coal power emissions in Australia remains the highest as it continues to rely on coal, which made up 48% of the country’s electricity generation (130.9 TWh) in 2022. Australia is also falling short of its 2030 goal to achieve 82% share of renewables in power generation by 2030.

In addition, the vast resource of coal has made Australia an enabler for other countries in becoming polluters as they rank second in the world as largest coal exporter after Indonesia.

Emissions per capita increasing in six G20 countries

Two G20 countries — Indonesia and Türkiye — saw notable rises in coal power emissions per capita over the last seven years, although still below the world average.

Indonesia witnessed the highest percentage rise among the G20, with per capita coal power emissions surging by 56% from 2015 to 2022 (+0.2 tCO2). Türkiye also experienced a significant increase of 41% in emissions per capita (+0.3 tCO2).

In China, per capita coal power emissions rose by 30% (+0.7 tCO2 from 2015 to 2022), which were only below Australia and South Korea. But unlike Australia and South Korea, this was due to rapidly growing demand outpacing the growth in clean generation. Since 2015, its per capita coal emissions have increased by about 4% annually on average, despite 670 GW of renewables being added in the same period.

India experienced a 29% increase in seven years (+0.2 tCO2). Both countries are experiencing rapid electricity demand growth, which is outpacing even the massive renewables expansion in recent years. As a result, their coal-fired generation has also increased in this period.

Russia’s per capita emissions also grew by 20% since 2015 (+0.17 tCO2). Japan, while showing a relatively modest increase, saw its per capita coal power emissions inch up by 2% from 2015 (+0.04 tCO2).

The rises in emissions per capita stem from the ongoing use of coal to meet the pick up in demand as pandemic restrictions ease, as well as the extreme weather events in summer and winter which drove coal generation up.

G20 needs to build renewables much faster

Although per capita emissions have declined in most G20 countries since 2015, this is not enough to reduce global coal power emissions per capita, nor the overall G20 coal power emissions per capita. In fact, the G20 per capita coal emissions slightly increased by about 9% from 1.5 tonnes of carbon dioxide in 2015 to 1.6 tonnes of carbon dioxide in 2022.

Coal power is still rising, where it needs to be rapidly falling. Concerted efforts are required to accelerate the transition to renewables and effectively phase down coal power. Adopting renewables on a broader scale will play a pivotal role in expediting the clean power transition, which is essential to significantly reduce per capita coal power emissions.

Opportunity for G20 to take centre stage on an ambitious global renewables goal, leading to an accelerated transition to clean power.

The G20 nations are at a critical juncture to show leadership and drive global actions to end fossil fuels and usher in an era of clean power. As the world’s largest economies, the G20 has the opportunity to prepare the scene at the G20 Summit for determined actions:

Investing in renewables, rather than persisting with coal dependency, brings multiple benefits. Renewables provide homegrown clean power, curb emissions, bolster energy security and spur economic growth through innovation and job creation.
