Forest Carbon


Mind the gap: Study shows estimates of current land-based emissions vary between models due to differing definitions
by International Institute for Applied Systems Analysis in, Nov 22, 2023. “A new study published in Nature demonstrates that estimates of current land-based emissions vary between scientific models and national greenhouse gas inventories due to differing definitions of what qualifies as “managed” land and human-induced, or anthropogenic removals on that land, and shows how global mitigation benchmarks change when accounting for land use, land-use change, and forestry (LULUCF) fluxes in scientific models from the national inventory perspective.”

Canada’s “Managed and Unmanaged Forests”. Screen capture (Source). Comment: I guess if the forests are potentially readily accessible to intensive forestry but we leave them alone, we consider them “managed”. ‘Sure makes the forestry-related GHG balances look better; surely obscures the real impacts of intensive forestry practices on GHG balances.

P.E.I.’s new forestry commission lists 5 ways to modernize how wood becomes energy
Arturo Chang · CBC News. July 20, 2023: The commission offered five recommendations:
– That all biomass supply contracts for the 44 provincially owned buildings should be renegotiated to provide more clarity.
– That there is a clearer definition of biomass in those revised contracts.
– That for future projects, there’s a comprehensive review of the environmental impact of biomass harvesting on the long-term wood supply, including an assessment of the carbon emissions from moving the product from harvest sites to the plant.
– That the government more clearly define the role of public forests as a potential source of biomass for provincially owned buildings.
– That it determines how the forest biomass sector can contribute to the province’s “Path to Net Zero” by 2040.

P.E.I. seeks feedback on sustainability of biomass supply as part of forest policy
By Todd Humber in Canadian Biomass
“The paper posed four questions on the issue of the sustainability of biomass supply:
“-What should be the role of the Forests, Fish and Wildlife Division in monitoring the harvest of biomass used for heating and other purposes?
-What system of measurement should be used to define sustainability of biomass harvesting on individual woodlots and on a province-wide basis?
-What system of measurement should be used by the provincial government to assess applications for wood biomass projects under the Environmental Protection Act’s Environmental Impact Assessment process?
-Should limits be placed on biomass harvesting and, if so, by what means?
The discussion paper and survey are available at PEI Forestry Commission. The deadline for feedback is August 31, 2024”

Forests can add value without being clearcut
By Moira Donovan in National Observer. “In Nova Scotia, forests are potential wellsprings of biodiversity, sustainable livelihoods, and long-term climate change mitigation. Yet despite that potential, thousands of acres of forests are clearcut every year in the name of short-term profit. A company called Growing Forests is now aiming to combat that immediate threat, using ecological forestry and carbon offsets as an alternative to unsustainable practices.While the project has the potential to protect the long-term health of the forest — and of the planet — Dale Prest, Growing Forests’ CEO, says at its heart the company is motivated by a shared interest in rural communities: to protect and restore forests, and maintain local ownership of the land. “Carbon is just the way we pay for that to happen,” he says.”

3 Reasons Why Forest Carbon Offsets Don’t Always Work
Andrew Moore in NC State News. “While reducing emissions through carbon offsets is important to reaching global net zero goals, the effectiveness of the REDD+ framework remains in question. Erin Sills, the Edwin F. Conger Professor of forest economics at NC State, along with other researchers, studied REDD+ projects that generate carbon offsets for the voluntary market and found that many projects overestimate their impact.”

MPs urge government to get serious about tracking logging emissions
By Kate Allen Climate Change Reporter for The Star. “Every year, the federal government reports how much the logging industry contributes to our economy: $34.8 billion of Canada’s GDP in 2021, according to the latest figures. But how much does that sector contribute to the climate crisis? The answer is hazy, because of what environmental groups, scientists, and Ottawa’s environment commissioner have described as a lack of transparency around the federal government’s emissions reporting. Now a group of more than 25 MPs and senators, including nine Liberals, have added their names to the growing chorus of calls to change how emissions from logging are tracked, saying the current system is “undermining public accountability and creating a hidden subsidy for carbon pollution from the sector.”

Oil and gas must cut emissions more than a third by 2030
By Mia Rabson, The Canadian Press reported in “Companies can buy offset credits or contribute to a decarbonization fund that would lower their required reduction”
Related, see: The arc of progress in global carbon markets bends toward integrity by Manulife March 22, 2023 “As the world continues to adapt to climate change, carbon markets are integral to aiding the transition to net-zero emissions. Carbon markets must continue to strengthen to build stakeholder confidence and ensure that climate mitigation is delivered, highlighting the importance of establishing clear carbon standards that are systematically applied throughout development and management lifecycles to ensure quality and integrity.” Comment: Time for the B.S. about forest carbon accounting to end if NS woodlot/forested land owners and managers want to benefit which would also be good for our forests and biodiversity.

Carbon removal is needed to achieve net zero but has its own climate risks
In The Conversation. “…Net-zero carbon dioxide (CO₂) emissions refers to a balance between CO₂ emissions into the atmosphere and CO₂ removals from the atmosphere, such that the net effect on CO₂ levels in the atmosphere is zero. It is often assumed that if such a balance is achieved, the net effect on climate would also be zero. However, in a recent paper in Nature Climate Change, we show that unless we consider a number of other factors — such as permanence of carbon stored in vegetation and soils, changes in the reflectivity of landscapes and the full suite of greenhouse gases emitted — balancing CO₂ emissions with removals will not achieve the intended climate goal.

Temporary carbon storage in forests has climate value — but we need to get the accounting right
H. Damon Matthews et al., in The Conversation Sep 28, 2023. “…what if we measured and tracked both the amount and time of carbon storage? As we show in our new research published in Nature Communications, this can be done using the tonne-year metric — defined as the amount of carbon storage multiplied by the number of years that it remains stored.”

What does carbon offset actually mean for US forests?
by Sarah Kuta, University of Colorado at Boulder in “In a single calendar year, a mature tree can take in roughly 48 pounds of CO2, which remains stored in its woody fibers until some event—like a wildfire, a pest infestation or clearcutting by a logging company—triggers its release into the atmosphere. This natural process is at the heart of the world’s carbon offset industry, in which companies and consumers counteract their CO2 emissions by buying credits from projects that remove or reduce emissions. Carbon offsetting is part of a broader group of so-called nature-based solutions to human-caused climate change. Now, researchers at the University of Colorado Boulder are working to bring more transparency to this fast-growing industry.” Cites this paper: Lilli Kaarakka et al, Managing forests for carbon–Status of the forest carbon offset markets in the United States, PLOS Climate (2023).

The effectiveness of global protected areas for climate change mitigation
L. Duncanson et al. in Nature Communications “Forests play a critical role in stabilizing Earth’s climate. Establishing protected areas (PAs) represents one approach to forest conservation, but PAs were rarely created to mitigate climate change. The global impact of PAs on the carbon cycle has not previously been quantified due to a lack of accurate global-scale carbon stock maps. Here we used ~412 million lidar samples from NASA’s GEDI mission to estimate a total PA aboveground carbon (C) stock of 61.43 Gt (+/− 0.31), 26% of all mapped terrestrial woody C. Of this total, 9.65 + /− 0.88 Gt of additional carbon was attributed to PA status. These higher C stocks are primarily from avoided emissions from deforestation and degradation in PAs compared to unprotected forests. This total is roughly equivalent to one year of annual global fossil fuel emissions. These results underscore the importance of conservation of high biomass forests for avoiding carbon emissions and preserving future sequestration.”
