Greenhouse gas emissions rise among G8 nations

CO2 Removal Technologies address climate change via negative emissions, including carbon capture, reforestation, soil carbon, biochar, BECCS, DAC, and mineralization, helping meet Paris Agreement targets while managing costs, land use, and infrastructure demands.

Key Points

Methods to extract or sequester atmospheric CO2, combining natural and engineered approaches to limit warming.

✅ Includes reforestation, soil carbon, biochar, BECCS, DAC, mineralization

✅ Balances climate goals with costs, land, energy, and infrastructure

✅ Key to Paris Agreement targets under 1.5-2.0 °C warming

The world is, on average, 1.1 degrees Celsius warmer today than it was in 1850. If this trend continues, our planet will be 2 – 3 degrees hotter by the end of this century, according to the Intergovernmental Panel on Climate Change (IPCC).

The main reason for this temperature rise is higher levels of atmospheric carbon dioxide, which cause the atmosphere to trap heat radiating from the Earth into space. Since 1850, the proportion of CO2 in the air has increased, with record greenhouse gas concentrations documented, from 0.029% to 0.041% (288 ppm to 414 ppm).

This is directly related to the burning of coal, oil and gas, which were created from forests, plankton and plants over millions of years. Back then, they stored CO2 and kept it out of the atmosphere, but as fossil fuels are burned, that CO2 is released. Other contributing factors include industrialized agriculture and slash-and-burn land clearing techniques, and emissions from SF6 in electrical equipment are also concerning today.

Over the past 50 years, more than 1200 billion tons of CO2 have been emitted into the planet's atmosphere — 36.6 billion tons in 2018 alone, though global emissions flatlined in 2019 before rising again. As a result, the global average temperature has risen by 0.8 degrees in just half a century.

Atmospheric CO2 should remain at a minimum
In 2015, the world came together to sign the Paris Climate Agreement which set the goal of limiting global temperature rise to well below 2 degrees — 1.5 degrees, if possible.

The agreement limits the amount of CO2 that can be released into the atmosphere, providing a benchmark for the global energy transition now underway. According to the IPCC, if a maximum of around 300 billion tons were emitted, there would be a 50% chance of limiting global temperature rise to 1.5 degrees. If CO2 emissions remain the same, however, the CO2 'budget' would be used up in just seven years.

According to the IPCC's report on the 1.5 degree target, negative emissions are also necessary to achieve the climate targets.

Using reforestation to remove CO2
One planned measure to stop too much CO2 from being released into the atmosphere is reforestation. According to studies, 3.6 billion tons of CO2 — around 10% of current CO2 emissions — could be saved every year during the growth phase. However, a study by researchers at the Swiss Federal Institute of Technology, ETH Zurich, stresses that achieving this would require the use of land areas equivalent in size to the entire US.

Reforestation has potential to tackle the climate crisis by capturing CO2. But it would require a large amount of space

More humus in the soil
Humus in the soil stores a lot of carbon. But this is being released through the industrialization of agriculture. The amount of humus in the soil can be increased by using catch crops and plants with deep roots as well as by working harvest remnants back into the ground and avoiding deep plowing. According to a study by the German Institute for International and Security Affairs (SWP) on using targeted CO2 extraction as a part of EU climate policy, between two and five billion tons of CO2 could be saved with a global build-up of humus reserves.

Biochar shows promise
Some scientists see biochar as a promising technology for keeping CO2 out of the atmosphere. Biochar is created when organic material is heated and pressurized in a zero or very low-oxygen environment. In powdered form, the biochar is then spread on arable land where it acts as a fertilizer. This also increases the amount of carbon content in the soil. According to the same study from the SWP, global application of this technology could save between 0.5 and two billion tons of CO2 every year.

Storing CO2 in the ground
Storing CO2 deep in the Earth is already well-known and practiced on Norway's oil fields, for example. However, the process is still controversial, as storing CO2 underground can lead to earthquakes and leakage in the long-term. A different method is currently being practiced in Iceland, in which CO2 is sequestered into porous basalt rock to be mineralized into stone. Both methods still require more research, however, with new DOE funding supporting carbon capture, utilization, and storage.

Capturing CO2 to be held underground is done by using chemical processes which effectively extract the gas from the ambient air, and some researchers are exploring CO2-to-electricity concepts for utilization. This method is known as direct air capture (DAC) and is already practiced in other parts of Europe.  As there is no limit to the amount of CO2 that can be captured, it is considered to have great potential. However, the main disadvantage is the cost — currently around €550 ($650) per ton. Some scientists believe that mass production of DAC systems could bring prices down to €50 per ton by 2050. It is already considered a key technology for future climate protection.

Carbon capture facilities are still very expensive and take up a huge amount of space

Another way of extracting CO2 from the air is via biomass. Plants grow and are burned in a power plant to produce electricity. CO2 is then extracted from the exhaust gas of the power plant and stored deep in the Earth, with new U.S. power plant rules poised to test such carbon capture approaches.

The big problem with this technology, known as bio-energy carbon capture and storage (BECCS) is the huge amount of space required. According to Felix Creutzig from the Mercator Institute on Global Commons and Climate Change (MCC) in Berlin, it will therefore only play "a minor role" in CO2 removal technologies.

CO2 bound by rock minerals
In this process, carbonate and silicate rocks are mined, ground and scattered on agricultural land or on the surface water of the ocean, where they collect CO2 over a period of years. According to researchers, by the middle of this century it would be possible to capture two to four billion tons of CO2 every year using this technique. The main challenges are primarily the quantities of stone required, and building the necessary infrastructure. Concrete plans have not yet been researched.

Not an option: Fertilizing the sea with iron
The idea is use iron to fertilize the ocean, thereby increasing its nuturient content, which would allow plankton to grow stronger and capture more CO2. However, both the process and possible side effects are very controversial. "This is rarely treated as a serious option in research," concludes SWP study authors Oliver Geden and Felix Schenuit.

Texas Electricity Prices are shifting as deregulation matures, with competitive market shopping lowering residential rates, narrowing gaps with regulated areas, and EIA data showing long term declines versus national averages across most Texans.

Key Points

Texas Electricity Prices are average residential rates in deregulated and regulated markets across the state.

✅ Deregulated areas saw 17.4% residential price declines since 2006

✅ Regulated zones experienced a 5.5% increase over the same period

✅ Competitive shopping narrowed the gap; Texas averaged below US

Shopping for electricity is becoming cheaper for most Texans, according to a new study from the Texas Coalition for Affordable Power. But for those who live in an area with only one electricity provider, prices have increased in a recent 10-year period, the study says.

About 85 percent of Texans can purchase electricity from a number of providers in a deregulated marketplace, while the remaining 15 percent must buy power from a single provider, often an electric cooperative, in their area.

The report from the Texas Coalition for Affordable Power, which advocates for cities and local governments and negotiates their power contracts, pulls information from the U.S. Energy Information Administration to compare prices for Texans in the two models. Most Texans could begin choosing their electricity provider in 2002.

Buying power tends to be more expensive for Texans who live in a part of the state with a deregulated electricity market. But that gap is continuing to shrink as Texans become more willing to shop for power, even as electricity complaints have periodically risen. In 2015, the gap “was the smallest since the beginning of deregulation,” according to the report.

Between 2006 and 2015, the last year for which data is available, average residential electric prices for Texans in a competitive market decreased by 17.4 percent, while average prices increased by 5.5 percent in the regulated areas, even as the Texas power grid has periodically faced stress.

“These residential price declines are promising, and show the retail electric market is maturing,” Jay Doegey, executive director for the Texas Coalition for Affordable Power, said in a statement. “We’re encouraged by the price declines, but more progress is needed.”

The study attributes the decline to the prevalence of “low-priced individual deals” in the competitive areas, while policymakers consider market reforms to bolster reliability.

Overall, the average price of electricity in Texas (which produces and consumes the most electricity in the U.S.) — including the price in the deregulated marketplace, for the third time in four years — was below the national average in 2015.

Brazil ICMS Tax Cap limits state VAT on fuels, natural gas, electricity, communications, and transit, promising short-term price relief amid inflation, with federal compensation to states and potential legal challenges affecting investments and ANP auctions.

Key Points

A policy capping state VAT at 17-18 percent on fuels, electricity, and services to temper prices and inflation.

✅ Caps VAT to 17-18% on fuels, power, telecom, transit

✅ Short-term relief; medium-long term impact uncertain

✅ Federal compensation; potential court challenges, investment risk

Brazil’s congress approved a bill that limits the ICMS tax rate that state governments can charge on fuels, natural gas, electricity, communications, and public transportation. 

Local lawyers told BNamericas that the measure may reduce fuel and power prices in the short term, similar to Brazil power sector relief loans seen during the pandemic, but it is unlikely to produce any major effects in the medium and long term. 

In most states the ceiling was set at 17% or 18% and the federal government will pay compensation to the states for lost tax revenue until December 31, via reduced payments on debts that states owe the federal government.

The bill will become law once signed by President Jair Bolsonaro, who pushed strongly for the proposal with an eye on his struggling reelection campaign for the October presidential election. Double-digit inflation has turned into a major election issue and fuel and electricity prices have been among the main inflation drivers, as seen in EU energy-driven inflation across the bloc this year. Congress’ approval of the bill is seen by analysts as political victory for the Brazilian leader.

How much difference will it make?

Marcus Francisco, tax specialist and partner at Villemor Amaral Advogados, said that in the formation of fuel and electricity prices there are other factors, including high natural gas prices, that drive increases.

“In the case of fuels, if the barrel of oil [price] increases, automatically the final price for the consumer will go up. For electricity, on the other hand, there are several subsidies and policy choices such as Florida rejecting federal solar incentives that are part of the price and that can increase the rate [paid],” he said. 

There is also a possibility that some states will take the issue to the supreme court since ICMS is a key source of revenue for them, Francisco added.

Tiago Severini, a partner at law firm Vieira Rezende, said the comparison between the revenue impact and the effective price reduction, based on the estimates made by the states and the federal government, seems disproportionate, and, as seen in Europe, rolling back European electricity prices is often tougher than it appears. 

“In other words, a large tax collection impact is generated, which is quite unequal among the different states, for a not so strong price reduction,” he said.

“Due to the lack of clarity regarding the precision of the calculations involved, it’s difficult even to assess the adequacy of the offsets the federal government has been considering, and international cases such as France's new electricity pricing scheme illustrate how complex it can be to align fiscal offsets with regulatory constraints, to cover the cost it would have with the compensation for the states” Severini added.

The compensation ideas that are known so far include hiking other taxes, such as the social contribution on net profits (CSLL) that is paid by oil and gas firms focused on exploration and production.

“This can generate severe adverse effects, such as legal disputes, reduced investments in the country, and reduced attractiveness of the new auctions by [sector regulator] ANP, and costly interventions like the Texas electricity market bailout after extreme weather events,” Severini said.

Manitoba Clean Electricity Investment will upgrade hydroelectric turbines, expand a 230 kV transmission network, and deliver reliable, affordable low-carbon power, reducing greenhouse gas emissions and strengthening grid reliability across Portage la Prairie and Winnipeg River.

Key Points

Joint federal-provincial funding to upgrade hydro turbines and build a 230 kV grid, boosting reliable, low-carbon power.

✅ $314M for new turbines at Pointe du Bois (+52 MW capacity)

✅ $161.6M for 230 kV transmission in Portage la Prairie

✅ Cuts Brandon Generating Station emissions by ~37%

The governments of Canada and Manitoba have announced a joint investment of $475.6 million to strengthen Manitoba’s clean electricity grid that can support neighboring provinces with clean power and ensure continued supply of affordable and reliable low-carbon energy.

This federal-provincial investment provides $314 million for eight new hydroelectric turbines at the 75 MW Pointe du Bois Generating Station on the Winnipeg River, as well as $161.6 million to build a new 230 kV transmission network in the Portage la Prairie area, bolstering power sales to SaskPower and regional reliability.

The $314 million joint investment in the Pointe du Bois Renewable Energy Project includes $114.1 million from the Government of Canada and nearly $200 million from the Government of Manitoba. The joint investment will enable Manitoba Hydro to replace eight generating units that are at the end of their lifecycle, amid looming new generation needs for the province. The new, more efficient units will increase the capacity of the Pointe du Bois generating station by 52 MW.

The $161.6 million joint investment in the Portage Area Capacity Enhancement project includes $70.9 million from the Government of Canada and $90.6 million from the Government of Manitoba. The joint investment will support the construction of a new transmission line to enhance reliability for customers across southwest Manitoba and help Manitoba Hydro meet increasing demand, with projections that demand could double over the next two decades. By decreasing Manitoba’s reliance on its last grid-connected fossil-fuel generating station, this investment will reduce greenhouse gas emissions at the Brandon Generating Station by about 37%.

The federal government’s total contribution of $184.9 million is provided through the Green Infrastructure Stream of the Investing in Canada Plan, alongside efforts to improve interprovincial grid integration such as NB Power agreements with Hydro-Quebec that strengthen regional reliability. This federal funding is conditional on meeting Indigenous consultation requirements, as well as environmental assessment obligations. Including today’s announcement, the Green Infrastructure Stream has supported 38 infrastructure projects in Manitoba, for a total federal contribution of more than $766.8 million and a total provincial contribution of over $658.4 million.

“A key part of our economic plan is making Canada a clean electricity superpower. Today’s announcement in Manitoba will deliver clean, reliable, and affordable electricity to people and businesses across the province—and we will continue working to expand our clean electricity grid and create great careers for people from coast to coast to coast,” said Deputy Prime Minister and Finance Minister Chrystia Freeland.

The federal government will continue to invest in making Canada a clean electricity superpower, supporting provincial initiatives like Hydro-Quebec's fossil-free strategy that complement these investments to ensure Canadians from coast to coast to coast have the affordable and reliable clean electricity they need today and for generations to come.

“Manitoba Hydro is extremely pleased to be receiving this federal funding through the Green Infrastructure Stream of the Investing in Canada Infrastructure Program. The investments we are making in both these critical infrastructure projects will help provide Manitobans with energy for life and power our province’s economic growth with clean, reliable, renewable hydroelectricity. These projects build on our legacy of investments in renewable energy over the past 100 years, as we work towards a lower carbon future for all Manitobans,” said Jay Grewal, president and chief executive officer of Manitoba Hydro.

About 97% of Manitoba’s electricity is generated from clean hydro, with most of the remaining 3% coming from wind generation. Manitoba’s abundant clean electricity has resulted in Manitobans paying 9.455 ¢/kWh — the second-lowest electricity rate in Canada, though limits on serving new energy-intensive customers have been flagged recently.

Alberta Energy-Only Electricity Market faces capacity market debate, AESO price cap review, and coal-to-gas shifts by TransAlta and Capital Power, balancing reliability with volatility as investment signals evolve across Alberta's grid.

Key Points

An energy market paying generators only for electricity sold, with AESO oversight and a price cap guiding new capacity.

✅ AESO reviewing $999 per MW-h wholesale price cap.

✅ UCP retained energy-only; capacity market plan cancelled.

✅ TransAlta and Capital Power shift to coal-to-gas.

The Kenney government’s decision to cancel the redesign of Alberta’s electricity system to a capacity market won’t side-track two of the province’s largest power generators from converting coal-fired facilities to burn natural gas as part of Alberta’s shift from coal to cleaner energy overall.

But other changes could be coming to the province’s existing energy-only electricity market — including the alteration of the $999 per megawatt-hour (MW-h) wholesale price cap in Alberta.

The heads of TransAlta Corp. and Capital Power Corp. are proceeding with strategies to convert existing coal-fired power generating facilities to use natural gas in the coming years.

Calgary-based TransAlta first announced in 2017 that it would make the switch, as the NDP government was in the midst of overhauling the electricity sector and wind generation began to outpace coal in the province.

At the time, the Notley government planned to phase out coal-fired power by 2030, even as Alberta moved to retire coal by 2023 in practice, and shift Alberta into an electricity capacity market in 2021.

Such a move, made on the recommendation of the Alberta Electric System Operator (AESO), was intended to reduce price volatility and ensure system reliability.

Under the energy-only market, generators receive payments for electricity produced and sold into the grid. In a capacity market, generators are also paid for having power available on demand, regardless of how often they sell energy into the provincial grid.

The UCP government decided last month to ditch plans for a capacity market after consulting with the sector, saying it would be better for consumers.

On a conference call, TransAlta CEO Dawn Farrell said the company will convert coal-fired generating plants to burn gas, although it may alter the mix between simple conversions and switching to so-called “hybrid” plants.

(A hybrid conversion is a larger and more-expensive switch, as it includes installing a new gas turbine and heat-recovery steam generator, but it creates a highly efficient combined cycle unit.)

“Our view is fundamentally that carbon will be priced over the next 20 years no matter what,” she said Friday.

“We cannot get off coal fast enough in this company, and gas right now in Alberta is extremely inexpensive…

“So our coal-to-gas strategy is completely predicated on our belief that it’s not smart to be in carbon-intensive fuels for the future.”

Elsewhere in Canada, the Stop the Shock campaign has advocated for reviving coal power, underscoring ongoing policy debates.

The company said it’s planning the coal-to-gas conversion and re-powering of some or all of the units at its Keephills and Sundance facilities to gas-fired generation sometime between 2020 and 2023.

Similarly, Capital Power CEO Brian Vaasjo said the Edmonton-based company is moving ahead with a project that will allow it to burn both coal and natural gas at its Genesee generating station, even as Ontario’s energy minister sought to explore a halt to natural gas generation elsewhere.

In June, the company announced it would spend an estimated $50 million between 2019 and 2021 to allow it to use gas at the facility.

“What we’re doing is going to be dual fuel, so we will be able to operate 100 per cent natural gas or 100 per cent coal and everything in between,” Vaasjo said in an interview.

“You can expect to see we will be burning coal in the winter when natural gas prices are high, and we will be burning natural gas in summer when gas prices are real low.”

The transition comes as the government’s decision to stick with the energy-only market has been welcomed by players in the industry, and as Alberta's electricity future increasingly leans on wind resources.

A study by electricity consultancy EDC Associates found the capacity market would result in consumers paying an extra $1.4 billion in direct costs in 2021-22, as it required more generation to come online earlier than expected.

These additional costs would have accumulated to $10 billion by 2030, said EDC chief executive Duane-Reid Carlson.

For Capital Power, the decision to stick with the current system makes the province more investable in the future. Vaasjo said there was great uncertainty about the transition to a capacity market, and the possibility of rules shifting further.

Officials with Enmax Corp. said the city-owned utility would not have invested in future generation under the proposed capacity market.

“There is no short-term need (today) for new generation, so we’re just looking at the market and saying, ‘OK, as it evolves, we will see what happens,’” said Enmax vice-president Tim Boston.

Sticking with the energy-only market doesn’t mean Alberta will keep the existing rules.

In a July 25 letter, Alberta Energy Minister Sonya Savage directed AESO chair Will Bridge to examine if changes to the existing market are needed and report back by July 2020.

AESO, which manages the power grid, has been asked to investigate whether the current price cap of $999 per megawatt-hour (MW-h) should be changed.

The price ceiling hasn’t been altered since the energy-only market was implemented by the Klein government about two decades ago.

While allowing prices to go higher would increase volatility, reflecting lessons from Europe’s power crisis about scarcity pricing, during periods of rising demand and limited supply, it would send a signal to generators when investment in new generation is required, said Kent Fellows, a research associate at the University of Calgary’s School of Public Policy.

“Keeping the price (cap) too low could end up costing us more in the long run,” he said.

In a 2016 report, AESO said the province examined raising the price cap to $5,000 per MW-h, but “determined that it was unlikely to be successful in attracting investment due to increased price volatility.”

However, the amount of future generation that will be required in Alberta has been scaled back by the province.

In the United States, the Electricity Reliability Council of Texas (ERCOT) allows wholesale power prices in the state to climb to a cap of $9,000 per megawatt hours as demand rises — as it did Tuesday in the midst of a heat wave, according to Bloomberg.

Jim Wachowich, legal counsel for the Consumers’ Coalition of Alberta, said while few players are exposed to spot electricity prices, he has yet to be convinced raising the cap would be good for Albertans.

“Someone has to show me the evidence, and I suspect that’s what the minister has asked the AESO to do,” he said.

Generators say they believe some tinkering is needed to the energy-only market to ensure new generation is built when it’s required.

“The No. 1 change that the government has to … think about is in pricing,” added Farrell.

“If you don’t have enough of a price signal in an energy-only market to attract new capital, you won’t get new capital — and you’ll run up against the wall.”

Ontario Electricity Rebate clarifies hydro rates as OEB aligns bills with inflation, shows true cost per kilowatt hour, and replaces Fair Hydro Plan; transparent on-bill credit offsets increases tied to nuclear refurbishment and supply costs.

Key Points

A line-item credit on Ontario hydro bills that offsets higher electricity costs and reflects OEB-set rates.

✅ Starts Nov. 1 with rates in line with inflation

✅ Shows true per-kWh cost plus separate rebate line

✅ Driven by nuclear refurbishment and supply costs

The Ontario Energy Board says electricity rate changes for households and small businesses will be going up starting next week.

The agency says rates are scheduled to increased by about $1.99 or nearly 2% for a typical residential customer who uses 700 kilowatt hours per month.

The provincial government said in March it would continue to subsidize hydro rates, through legislation to lower rates, and hold any increases to the rate of inflation.

The OEB says the new rates, which the board says are “in line” with inflation, will take effect Nov. 1 as changes for electricity consumers roll out and could be noticed on bills within a few weeks of that date.

Prices are increasing partly due to government legislation aimed at reflecting the actual cost of supply on bills, and partly due to the refurbishment of nuclear facilities, contributing to higher hydro bills for some consumers.

So, effective November 1, Ontario electricity bills will show the true cost of power, after a period of a fixed COVID-19 hydro rate, and will include the new Ontario Electricity Rebate.

Previously the electricity rebate was concealed within the price-per-kilowatt-hour line item on electricity statements, prompting Hydro One bill redesign discussions to improve clarity. This meant customers could not see how much the government rebate was reducing their monthly costs, and bills did not display the true cost of electricity used.

"People deserve facts and accountability, especially when it comes to hydro costs," said Energy Minister Rickford.

The new Ontario Electricity Rebate will appear as a transparent on-bill line item and will replace the former government's Fair Hydro Plan says a government news release. This change comes in response to the Auditor General's special report on the former government's Fair Hydro Plan which revealed that "the government created a needlessly complex accounting/financing structure for the electricity rate reduction in order to avoid showing a deficit or an increase in net debt."

"The Electricity Distributors Association commends the government's commitment to making Ontario's electricity bills more transparent," said Teresa Sarkesian, President of the Electricity Distributors Association. "As the part of our electricity system that is closest to customers, local hydro utilities appreciated the opportunity to work with the government on implementing this important initiative. We worked to ensure that customers who receive their electricity bill will have a clear understanding of the true cost of power and the amount of their on-bill rebate. Local hydro utilities are focused on making electricity more affordable, reducing red tape, and providing customers with a modern and reliable electricity system that works for them."

The average customer will see the electricity line on their bill rise, showing the real cost per kilowatt hour. The new Ontario Electricity Rebate will compensate for that rise, and will be displayed as a separate line item on hydro bills. The average residential bill will rise in line with the rate of inflation.
