IDEA 1
Forest-based bio-economy has
intrinsic sustainability assets, as
it contributes to a full-world
economic model, including
natural capital and ecosystem
services

• Economy is at the service of societal well-being, and societies can prosper
within the possibilities and limits offered by the natural environment.
• Things have to be ecologically sound to be economically viable (Piketty)
• Increasingly influential, as feasible alternative for the pillar model, which is
failing to keep society within planetary boundaries (Rockström et al. 2009
Nature; Steffen et al. 2015 Science)

should take up a leading position in
sustainability transition

SUSTAINABILITY ASPECTS OF THE BIO-ECONOMY
• Climate mitigation and adaptation
• Sustained yield
• Water
• Biodiversity
• Integration/Synergies
![Page 15: Sustainability of the forest-based Bio-economy · 2017-12-22 · Circular Bioeconomy: more than bioeconomy or circular economy Biomass Chemicals Materials Bioenergy Biofuels Food](https://reader034.fdocuments.net/reader034/viewer/2022052612/5f0f651b7e708231d443f257/html5/thumbnails/15.jpg)
SUSTAINABLE YIELD = maintenance of long-term
site productivity
It is good practice to minimize extraction of nutrients and to
compensate losses where needed
Overall limitation and site specific prohibition on stump and
harvesting residues extraction

Matter management across
the EU, DG ENV

SUSTAINED YIELD
Transition to biobased economy will lead to scarcer
and more valuable biomass
From a historical perspective biobased economies are
a threat to forest growing stocks
Sustained yields in and outside Europe will be at stake
and yield regulation will become a policy and
management challenge.
21st century biobased economy must demonstrate the
effectiveness of its sustained yield control tools
We propose a stress test on the existing control tools
in every European country

Beyond carbon:
forests for global ecosystem services
• Trees, forests and water: Cool insights for a hot world (Ellison et al. 2017, Global Environmental Change)
• Joint efforts between conventions

IDEA 3Several SD evaluation tools exist
with each its strengths &
weaknesses.
C&I and LCA are promising to
guide the circular bioeconomy
![Page 19: Sustainability of the forest-based Bio-economy · 2017-12-22 · Circular Bioeconomy: more than bioeconomy or circular economy Biomass Chemicals Materials Bioenergy Biofuels Food](https://reader034.fdocuments.net/reader034/viewer/2022052612/5f0f651b7e708231d443f257/html5/thumbnails/19.jpg)
IDEA 4Sustainability evaluation needs
consideration of the
whole chain from cradle to cradle,
includes both services as impacts,
and all aspects of sustainability

“purchased science”

Forests play key role in mitigation targets
• PARIS AGREEMENT: ¼ of anticipated global emission
reductions by 2030 (INDCs) in LULUCF(Grassi et al., 2017, Nature CC)
• LULUCF crucial to stay within 1.5°C

Climate mitigation in the forest sector
To manage or not to manage: that’s the question
LULUCF regulation? Solid bioenergy regulation?

Carbon storage in wood
• EU-POOL: 9t C for every ha
of productive forest
(Germany 22tC/ha, doubled
over the last 20 years) (Brunet
Navarro 2017, PhD KU Leuven, CASTLE Marie
Curie Training Network)
• CURRENT EU-SINK: about
10% of forest carbon sink
• SHORT TERM: maintaining
sink only at the expense of
forest C (Pili et al. 2015, Carbon Balance &
Management)
• LONG TERM: maintaining
sink by generalising CLT in
construction and cascading

the planet” Nature

Cascading
Move away from eternal recycling loops to realistic cascading scenarios.
Substitution• Move away from hybrid calculation between carbon accounting and GWP
calculation
• Use improved, dynamic displacement factors
• Do not consider all wood supply as substitution, but consider effective
substitution by marginal approach
PhD works Pau Brunet and Giuseppe Cardellini
![Page 29: Sustainability of the forest-based Bio-economy · 2017-12-22 · Circular Bioeconomy: more than bioeconomy or circular economy Biomass Chemicals Materials Bioenergy Biofuels Food](https://reader034.fdocuments.net/reader034/viewer/2022052612/5f0f651b7e708231d443f257/html5/thumbnails/29.jpg)
Cascading and substitution
• Mitigation effect of EU wood sector: effects of carbon stock change
(dashed lines) and overall mitigation effect with substitution (full lines) for
different scenarios (Brunet Navarro, 2017, PhD KU Leuven, CASTLE Marie Curie Training Network)
• Effect in 2030 compared to EU target for 2030 (2,272 Mt CO2):
BaU sc. 47.97 Mt CO2 (1.4%); Material sc. 94.91 Mt CO2 (2.8 %); Energy sc. 14.76 Mt CO2 (0.4 %);
Engineered wood sc. 59.99 Mt CO2 (1.8 %)

IDEA 5The climate mitigation potential of
forests is large but uncertain. The
climate mitigation potential of
wood products is smaller and
requires large transition efforts.
