Coal remains the primary fuel for global electricity generation, particularly in Asian countries

High energy prices, inflation, war, and the ongoing economic recovery from the pandemic has highlighted the general worldwide demand for electricity, particularly in Asia and Europe. The growing demand for electricity on these two continents has led some electricity producing plants to rely increasingly heavily on coal as a power source.

The electricity sector accounts for 34 per cent of the world’s energy-related carbon dioxide (CO2) emissions. In this Fact Sheet, we detail recent trends in electricity production and demand across the globe as well as CO2 emissions from the electricity sector worldwide.

Carbon dioxide emissions from the world’s top ten emitters between 2000 and 2022

A total of 38.2 gigatonnes (Gt) of energy-related CO2 was emitted globally in 2022, an increase of 53 per cent from 2000. However, the increase is not consistent for all countries; between 2000 and 2023, CO2 emissions trends diverged. Emissions from China, India, and Indonesia more than doubled in the last two decades, whereas emissions for other countries remained relatively consistent or even declined.

In 2022, Canada’s total energy-related CO2 emissions were 0.62 Gt, or 1.6 per cent of the global total. That compares to emissions of 0.64 Gt in South Korea, 1.09 Gt in Japan, 2.8 Gt in India, 5.0 Gt in the United States, and 13.0 Gt in China (see Figure 1).

Demand for electricity and sources of emissions

Global domestic electricity consumption increased from 13,188 terawatt-hours (TWh) in 2000 to 25,681 TWh in 2022 and estimates are that global demand for electricity will rise to 35,000 TWh by 2040.¹

That is a jump of 94 per cent, or 12,492 TWh, between 2000 and 2022. During the same period, electricity consumption in Asia rose a whopping 280 per cent. In Africa the demand for electricity increased by 90 per cent (see Figure 2). Coal remains the world’s largest source of fuel for electricity generation, with approximately 10,317 terawatt-hours of electricity generated by coal-fired plants in 2022 (see Figure 3).

In recent years, electricity generated from the combustion of coal declined in Canada, the United States, Europe, and Africa. However, electricity generated from coal combustion has continued to grow in China, India, and other parts of Asia.

Between 2000 and 2022, the share of coal-powered electricity generation in Asia increased from 49.8 to 56. 3 per cent, while in Canada it decreased from 19.4 per cent to less than 5 per cent.

Source of emissions in the electricity sector

The electricity sector accounts for 34 per cent of the carbon dioxide emitted across the world. The sector emitted 13.05 gigatonnes of CO2 in 2022, an increase of 5.01 Gt from 2000. In Asia, between 2000 and 2022, CO2 emissions from the electricity sector increased from 2.5 Gt to 8.3 Gt and the sector’s share of carbon dioxide (CO2) emissions increased from just over 32 per cent to well over 40 per cent (see Figure 5).

Coal burned to generate electricity accounts for the majority of the CO2 emitted in power generation. In 2022, coal-fired electricity\ generation accounted for 9.89 Gt, or nearly 76 per cent of the worldwide CO2 emissions from the electricity sector. The share was even higher in Asia where 92 per cent of emissions from the electricity sector come from coal combustion. Asian coal-fired plants accounted for 7.62 Gt of the total 8.26 Gt of emissions from the sector on that continent (see Figure 6).

Conclusion

The global electricity sector, and particularly the sector in Asia, is a major source of CO2 emissions. Relative to Canada’s existing carbon emissions, emissions from the coal-fired power plants worldwide will make any reductions in Canada’s carbon emissions and resulting job losses, higher taxes, and higher costs for consumers and businesses—meaningless.

As 56 per cent of the electricity in Asia is generated by coal-fired plants, a transition from coal- to gas-fired electricity generation in the region could lead to significant reductions in CO2 emissions, reducing emissions by 50 per cent on average. The corollary is that there is a potential market in Asia for natural gas extracted in and exported from Canada. Canada has an opportunity to play a useful and meaningful role in reducing CO2 emissions from the electricity sector by encouraging and contributing to the global natural gas market.

Sharing emissions reductions through Article 6 is possible when LNG replaces coal in power generation

With Asian countries continuing to rely on coal to fuel their growth, Canada can provide a cleaner alternative while having its efforts to reduce emissions recognized by the global community, says a new report. 

 Canada is getting closer to exporting some of the lowest-emitting liquefied natural gas (LNG) on the planet, with the first terminal nearing completion in British Columbia.  

 A Canadian think tank argues providing a significantly cleaner alternative to coal should merit credit for helping Asian countries reduce emissions under a global climate treaty. 

 “Sharing emissions reductions through Article 6 [of the Paris Agreement] is possible when LNG replaces coal in power generation,” writes Jerome Gessaroli, a senior fellow with the Macdonald Laurier Institute. 

“New LNG projects within British Columbia are amongst the least carbon-intensive sources of LNG in the world. BC’s LNG exports could lower global carbon emissions by displacing coal power, particularly in the Asia-Pacific region.” 

Adopted by the United Nations Framework Convention on Climate Change in 2015, the Paris Agreement was ratified by Canada on October 5, 2016. This agreement set forth the worldwide effort to mitigate the effects of climate change.  

Article 6 outlines that countries may pursue “voluntary cooperation” with others to implement their nationally determined efforts to reduce emissions.  

Coal use and coal plant construction are increasing each year in Asia as countries look to grow their economies.  

The increase in coal-fired power has ostensibly created a significant challenge to meeting climate targets as emissions from announced and planned plants alone are expected to be over 1,415 million tonnes of CO2 equivalent.

“Just over half of LNG Canada’s Phase 1 production capacity in British Columbia would result in approximately 1.2 Mt CO2e emissions annually,” Gessaroli writes.  

“Using the same production capacity to replace coal for power generation in Asia has the potential to significantly reduce emissions, ranging from 14.9 to 35.2 Mt CO2e per year. Such outcomes underscore the importance of international collaborative efforts.” 

Studies have concluded that LNG from Canada can provide a net benefit in emissions reduction when switching from coal.  

Last year, global energy research and consultancy firm Wood Mackenzie found that Canadian LNG could reduce net emissions in northeast Asia by an average of 188 million tonnes per year between 2022 and 2050.  

That’s three times the emissions of the entire province of B.C., which were 62 Mt in 2021, according to the provincial inventory. 

“If Article 6 is used, the assertion that British Columbia’s pursuit of LNG production would prevent the province from meeting its emission reduction becomes inaccurate,” Gessaroli said, noting Canada should announce its intent to use Article 6 as a tool to help meet its emissions reduction targets. 

“These are complex issues, but we can learn from other countries that have already established processes for managing such projects.”
