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).
1. The IEA’s Electricity Market Report 2022 states that nearly all of the increase is attributable to growing electricity consumption in developing countries across southeast Asia and Africa.

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).

Sources: IEA World Energy Statistics database and Enerdata
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).

Sources: IEA World Energy Statistics database and Enerdata
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.

Saskatchewan Indigenous leaders urging need for access to natural gas

“Come to my nation and see how my people are living, and the struggles that they have day to day out here because of the high cost of energy, of electric heat and propane.”
Indigenous communities across Canada need access to natural gas to reduce energy poverty, says a new report by Energy for a Secure Future (ESF).
It’s a serious issue that needs to be addressed, say Indigenous community and business leaders in Saskatchewan.
“We’re here today to implore upon the federal government that we need the installation of natural gas and access to natural gas so that we can have safe and reliable service,” said Guy Lonechild, CEO of the Regina-based First Nations Power Authority, on a March 11 ESF webinar.
Last year, 20 Saskatchewan communities moved a resolution at the Assembly of First Nations’ annual general assembly calling on the federal government to “immediately enhance” First Nations financial supports for “more desirable energy security measures such as natural gas for home heating.”
“We’ve been calling it heat poverty because that’s what it really is…our families are finding that they have to either choose between buying groceries or heating their home,” Chief Christine Longjohn of Sturgeon Lake First Nation said in the ESF report.
“We should be able to live comfortably within our homes. We want to be just like every other homeowner that has that choice to be able to use natural gas.”
At least 333 First Nations communities across Canada are not connected to natural gas utilities, according to the Canada Energy Regulator (CER).
ESF says that while there are many federal programs that help cover the upfront costs of accessing electricity, primarily from renewable sources, there are no comparable ones to support natural gas access.
“Most Canadian and Indigenous communities support actions to address climate change. However, the policy priority of reducing fossil fuel use has had unintended consequences,” the ESF report said.
“Recent funding support has been directed not at improving reliability or affordability of the energy, but rather at sustainability.”
Natural gas costs less than half — or even a quarter — of electricity prices in Alberta, British Columbia, Ontario, Manitoba and Saskatchewan, according to CER data.
“Natural gas is something NRCan [Natural Resources Canada] will not fund. It’s not considered a renewable for them,” said Chief Mark Fox of the Piapot First Nation, located about 50 kilometres northeast of Regina.
“Come to my nation and see how my people are living, and the struggles that they have day to day out here because of the high cost of energy, of electric heat and propane.”
According to ESF, some Indigenous communities compare the challenge of natural gas access to the multiyear effort to raise awareness and, ultimately funding, to address poor water quality and access on reserve.
“Natural gas is the new water,” Lonechild said.

The beauty of economic corridors: Inside Alberta’s work to link products with new markets

From the Canadian Energy Centre
Q&A with Devin Dreeshen, Minister of Transport and Economic Corridors
CEC: How have recent developments impacted Alberta’s ability to expand trade routes and access new markets for energy and natural resources?
Dreeshen: With the U.S. trade dispute going on right now, it’s great to see that other provinces and the federal government are taking an interest in our east, west and northern trade routes, something that we in Alberta have been advocating for a long time.
We signed agreements with Saskatchewan and Manitoba to have an economic corridor to stretch across the prairies, as well as a recent agreement with the Northwest Territories to go north. With the leadership of Premier Danielle Smith, she’s been working on a BC, prairie and three northern territories economic corridor agreement with pretty much the entire western and northern block of Canada.
There has been a tremendous amount of work trying to get Alberta products to market and to make sure we can build big projects in Canada again.
CEC: Which infrastructure projects, whether pipeline, rail or port expansions, do you see as the most viable for improving Alberta’s global market access?
Dreeshen: We look at everything. Obviously, pipelines are the safest way to transport oil and gas, but also rail is part of the mix of getting over four million barrels per day to markets around the world.
The beauty of economic corridors is that it’s a swath of land that can have any type of utility in it, whether it be a roadway, railway, pipeline or a utility line. When you have all the environmental permits that are approved in a timely manner, and you have that designated swath of land, it politically de-risks any type of project.
CEC: A key focus of your ministry has been expanding trade corridors, including an agreement with Saskatchewan and Manitoba to explore access to Hudson’s Bay. Is there any interest from industry in developing this corridor further?
Dreeshen: There’s been lots of talk [about] Hudson Bay, a trade corridor with rail and port access. We’ve seen some improvements to go to Churchill, but also an interest in the Nelson River.
We’re starting to see more confidence in the private sector and industry wanting to build these projects. It’s great that governments can get together and work on a common goal to build things here in Canada.
CEC: What is your vision for Alberta’s future as a leader in global trade, and how do economic corridors fit into that strategy?
Dreeshen: Premier Smith has talked about C-69 being repealed by the federal government [and] the reversal of the West Coast tanker ban, which targets Alberta energy going west out of the Pacific.
There’s a lot of work that needs to be done on the federal side. Alberta has been doing a lot of the heavy lifting when it comes to economic corridors.
We’ve asked the federal government if they could develop an economic corridor agency. We want to make sure that the federal government can come to the table, work with provinces [and] work with First Nations across this country to make sure that we can see these projects being built again here in Canada.
