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.

New children’s book demonstrates how the everyday world is connected to natural resources

From the Canadian Energy Centre
‘Today’s youth have the opportunity to lead us into the future with innovative solutions for environmental challenges’
After a 24-year career in oil sands land reclamation, author Tanya Richens is sharing her knowledge with young minds.
Her new book, From the Earth to Us: Discovering the Origins of Everyday Things, explores the relationship between natural resources and the things we use in everyday life, from computers and water bottles to batteries and solar panels.
“There is a gap in society’s understanding of where things come from. We are a society driven by consumerism and immediate gratification. We order something online, and it arrives on our doorstep the next day. We don’t stop to think about where it really came from or how it was made,” Richens says.
“There’s an ever-increasing societal position that mining is bad, and oil is even worse… But there’s a simple hypocrisy in those beliefs, since so many things in our lives are made from the raw materials that come from mining and oil and natural gas,” she says.
The book, illustrated by reclamation artist Shannon Carla King, follows young Hennessy Rose and her Cavalier King Charles Spaniel Riley on a trip to a children’s summer camp.
Hennessy’s mom is a guest speaker on the origin of everyday items and the relationship between humans and the earth. Through detailed explanations of items surrounding her, Hennessy’s mom teaches the kids how rocks, minerals, oil and gas from the earth are used to power and aid our lives, creating items such as building supplies, food and hair products, camping and sports equipment, and cell phones.

“I thought a simple and fun book explaining the raw materials needed to make everyday items would be valuable for all ages,” Richens says.
“When people feel personally connected to natural resources, they are more likely to promote sustainable practices. Today’s youth will have the opportunity to lead us into the future with innovative solutions for environmental challenges.”
Richens‘ career began with Alberta Environment, where she was a coordinator of reclamation approvals in the oil sands. She oversaw technical reviews of oil sands reclamation applications, communicated with statement of concern filers, coordinated public hearings and provided support for legislative changes.
She moved from government to Suncor Energy, ensuring the company’s compliance on reclamation projects and led initiatives to obtain reclamation certificates. She now works as an independent consultant.
Drawing on her wealth of experience in the field, Richens’ first book, Adventures in Land Reclamation: Exploring Jobs for a Greener Future, seeks to excite kids aged 9-12 years about jobs related to the environment and land reclamation.
Hoping to get From the Earth to Us into the hands of teachers, Richens is heading to the Edmonton Teachers Convention in late February. She says the book supports multiple learning outcomes in Alberta’s new science curriculum for grades 3, 4, 5 and 6.
“Ultimately, I’d like people to understand and acknowledge their individual part in the need for mining and oil and natural gas development. Until the naivety and hypocrisy in the world is addressed, I’m not sure that real environmental change is possible.”

U.S. tariffs or not, Canada needs to build new oil and gas pipeline space fast

From the Canadian Energy Centre
Expansion work underway takes on greater importance amid trade dispute
Last April, as the frozen landscape began its spring thaw, a 23-kilometre stretch of newly built pipeline started moving natural gas across northwest Alberta.
There was no fanfare when this small extension of TC Energy’s Nova Gas Transmission Limited (NGTL) system went online – adding room for more gas than all the homes in Calgary use every day.
It’s part of the ongoing expansion of the NGTL system, which connects natural gas from British Columbia and Alberta to the vast TC Energy network. In fact, one in every 10 molecules of natural gas moved across North America touches NGTL.
With new uncertainty emerging from Canada’s biggest oil and gas customer – the United States – there is a rallying cry to get new major pipelines built to reach across Canada and to wider markets.
Canada’s Natural Resources Minister Jonathan Wilkinson recently said the country should consider building a new west-east oil pipeline following U.S. President Donald Trump’s threat of tariffs, calling the current lack of cross-country pipelines a “vulnerability,” CBC reported.
“I think we need to reflect on that,” Wilkinson said. “That creates some degree of uncertainty. I think, in that context, we will as a country want to have some conversations about infrastructure that provides greater security for us.”
Many industry experts see the threat to Canada’s economy as a wake-up call for national competitiveness, arguing to keep up the momentum following the long-awaited completion of two massive pipelines across British Columbia over the last 18 months. Both of which took more than a decade to build amidst political turmoil, regulatory hurdles, activist opposition and huge cost overruns.
On May 1, 2024, the Trans Mountain pipeline expansion (TMX) started delivering crude oil to the West Coast, providing a much-needed outlet for Alberta’s growing oil production.
Several months before that, TC Energy finished work on the 670-kilometre Coastal Gaslink pipeline, which provides the first direct path for Canadian natural gas to reach international markets when the LNG Canada export terminal in Kitimat begins operating later this year.
TMX and Coastal GasLink provide enormous benefits for the Canadian economy, but neither are sufficient to meet the long-term growth of oil and gas production in Western Canada.
More oil pipeline capacity needed soon
TMX added 590,000 barrels per day of pipeline capacity, nearly tripling the volume of crude reaching the West Coast where it can be shipped to international markets.
In less than a year, the extra capacity has enabled Canadian oil production to reach all-time highs of more than five million barrels per day.
More oil reaching tidewater has also shrunk the traditional discount on Alberta’s heavy oil, generating an extra $10 billion in revenues, while crude oil exports to Asia have surged from $49 million in 2023 to $3.6 billion in 2024, according to ATB analyst Mark Parsons.
With oil production continuing to grow, the need for more pipeline space could return as soon as next year, according to analysts and major pipeline operators.
Even shortly after TMX began operation, S&P Global analysts Celina Hwang and Kevin Birn warned that “by early 2026, we forecast the need for further export capacity to ensure that the system remains balanced on pipeline economics.”
Pipeline owners are hoping to get ahead of another oil glut, with plans to expand existing systems already underway.
Trans Mountain vice-president Jason Balasch told Reuters the company is looking at projects that could add up to 300,000 barrels per day (bpd) of capacity within the next five years.
Meanwhile, Canada’s biggest oil pipeline company is working with Alberta’s government and other customers to expand its major export pipelines as part of the province’s plan to double crude production in the coming years.
Enbridge expects it can add as much as 300,000 bpd of capacity out of Western Canada by 2028 through optimization of its Mainline system and U.S. market access pipelines.
Enbridge spokesperson Gina Sutherland said the company can add capacity in a number of ways including system optimizations and the use of so-called drag reducing agents, which allow more fluid to flow by reducing turbulence.
LNG and electricity drive strong demand for natural gas
Growing global demand for energy also presents enormous opportunities for Canada’s natural gas industry, which also requires new transportation infrastructure to keep pace with demand at home and abroad.
The first phase of the LNG Canada export terminal is expected to begin shipping 1.8 billion cubic feet of gas per day (Bcf/d) later this year, spurring the first big step in an expected 30 per cent increase in gas production in Western Canada over the next decade.
With additional LNG projects in development and demand increasing, the spiderweb of pipes that gathers Alberta and B.C.’s abundant gas supplies need to continue to grow.
TC Energy CEO Francois Poirier is “very bullish” about the prosect of building a second phase of the recently completed Coastal GasLink pipeline connecting natural gas in northeast B.C. to LNG terminals on the coast at Kitimat.
The company is also continuously expanding NGTL, which transports about 80 per cent of Western Canada’s production, with more than $3 billion in growth projects planned by 2030 to add another 1 Bcf/d of capacity.
Meanwhile Enbridge sees about $7 billion in future growth opportunities on its natural gas system in British Columbia.
In addition to burgeoning LNG exports from Canada, the U.S. and Mexico, TC Energy sees huge potential for gas to continue replacing coal-fired electricity generation, especially as a boom in power-hunger data centres unfolds.
With such strong prospects for North America’s highly integrated energy system, Poirier recently argued in the Wall Street Journal that leaders should be focused on finding common ground for energy in the current trade dispute.
“Our collective strength on energy provides a chance to expand our economies, advance national security and reduce global emissions,“ he wrote in a Feb. 3 OpEd.
“By working together across North America and supporting the free flow of energy throughout the continent, we can achieve energy security, affordability and reliability more effectively than any country could achieve on its own.”
