Arctic Council experts tackle black carbon risk posed by wildfires
Forest fires, important sources of black carbon emissions, devastated Arctic regions around the world in 2018, and are an increasing concern for circumpolar nations, says the chair of the Arctic Council expert group on black carbon and methane.
The fires raged this summer in circumpolar countries like Sweden, Finland, Russia and Norway, including in their respective Arctic regions.
“It’s one of the reasons the Arctic Council has recognized (wildfires) more widely and it’s a topic that will be dealt with more widely by the Arctic Council working group,” said Mikael Hilden, chair of the expert group, in a phone interview with Eye on the Arctic from Helsinki.
“Our part in particular has been to look into the policy side of it and see, what kind of policies should one pursue? One cannot remove wildfires completely, but one can address them so they are less dangerous than they might otherwise be.”
The Arctic Council is a forum made up of world’s eight circumpolar nations: Canada, Denmark, Finland, Iceland, Norway, Sweden, Russia and the United States; and six Arctic Indigenous groups; the Aleut International Association, the Arctic Athabaskan Council, the Gwich’in Council International, the Inuit Circumpolar Council, the Russian Association of Indigenous Peoples of the North and the Saami Council.
The forum was established in 1996 to work on sustainable development and environmental protection in the North.

The expert group on black carbon was established by the forum in 2015 to help implement its goal of reducing black carbon and methane emissions.
The Arctic Council Expert Group on Black Carbon and Methane met for a two-day meeting in Helsinki January 16 and 17 to discuss their progress summary and recommendations for reducing emissions, that will be submitted to the next Arctic Council ministerial meeting in May.
Dangerous to health and environment
Black carbon and methane emissions are a serious concern for the world’s circumpolar countries because of this form of pollution’s role in warming the atmosphere. When black carbon is deposited on ice and snow, it absorbs heat, instead of reflecting heat from these surfaces, contributing to global warming.
After carbon dioxide, it’s the second biggest contributor to warming.
Black carbon is made up of fine matter produced by incomplete combustion of carbon-based fuels. It can be emitted by everything from diesel engines to forest fires.
Because black carbon particles are so small, they can be inhaled and have also been linked to respiratory and circulatory problems in humans.
Most boreal wildfires occur between March and October and can be caused either naturally, by things like lightening, or by humans.
The Arctic Council’s Arctic Monitoring and Assessment Programme described wildfire’s impact on the North in their 2015 assessment “Black carbon and ozone as Arctic climate forces.”
“Not only are emissions from fires within the Arctic important, but the Arctic atmosphere can be impacted by fires far from the region,” the assessment said.
“Wildfires can effectively inject emissions higher up into the atmosphere than other ground-based emission sources. Depending on the scale of the fire, fire plumes may penetrate the top of the boundary layer and so pollute the upper troposphere and even the stratosphere, where residence times are much longer and the pollutants can be transported greater distances.”
Mixed wildfire picture in North America
Alaska Public Media reported this summer that the American state had experienced a lower than average fire season this summer.
Canada’s Northwest Territories also experienced fewer wildfires in 2018 compared to the average. (Twenty-five fires and 11,271 hectares burnt, compared to the 25 year average of 172 fires and 402,976 hectares burnt, according to the territory’s Department of Environment and Natural Resources.)
However, wildfires burned in Canada’s neighbouring Yukon territory as well as the southern Canadian provinces of British Columbia, Saskatchewan, Alberta and Ontario.
Among other issues the expert group is discussing is fire containment and preparedness.
Norah Foy, a science officer at the federal department of Environment and Climate Change Canada, and a part of the expert group on black carbon since 2017, says exchanging with other circumpolar experts on emerging black carbon concerns like wildfires means faster progress on mitigation efforts.
“The cooperation and collaboration is invaluable,” Foy said in a telephone interview. “The Arctic Council is really special because it’s a collaborative fora. Everything is based on consensus. It’s less formal than most other international fora so it allows for more free exchange especially on the expert group and working group level. This allows people to share innovative ideas that work in their countries and these can often be applied across the Arctic, or parts of them can be applied across the Arctic, leading best practices to be uptaken regionally.”
“The conditions, although they are quite different, between the different Arctic countries, there are some specific features that the Arctic countries share,” said Mikael Hilden. “By sharing experiences, sharing knowledge, then you can, in a way, experiment your way forward so you can make faster progress than if you were each country by yourself.”
Small actions can lead to longterm solutions
Hilden says taking measures to reduce black carbon emissions is important because results can be measured quickly. Current priority areas are transport, oil and gas production, domestic heating and burning, and solid waste management.
The expert group is made up of everyone from scientists to policy advisers and includes members of Arctic Council countries, along with Arctic Council observer countries like Germany and Japan.
Because most black carbon in the Arctic is not produced in the Arctic, having other countries participate in the working group is particularly important, he said.
“There’s been an interest in the Arctic Council work on black carbon by non-Arctic countries such as Mexico and others, plus the Arctic Council has also invited explicitly the so-called observer countries to join in. We have, of course, big observer countries such as Chin and India for whom the black carbon issue is clearly an important local health issue in addition to the Arctic dimension.
“The main message is that, yes, the big picture is the progress, and is the goal to reduce the emissions overall. But, at the same time, one should do small scale actions and scale up. This way of progressing is what we hope this work will advance.”
