The value of wood: impacts on the environment and sustainability
Without doubt, wood is one of the most environmentally and
sustainable friendly material. To address global challenges such as climate
change, a growing population and resource scarcity, Europe must find pathways
to produce goods, food and energy by using renewable organic materials more
widely.
In this sense, the promotion of timber construction is
anchored in the bio-economy concept. The European sawmills industry makes
market products with a small carbon footprint, from raw material procured from
sustainably managed forests. Companies process hardwood and softwood for a wide
range of construction and furniture products.
The Forum
International Forum “The Value of Wood,” was held in
Brussels, in conjunction with the International Day of Forests on 21 March
2017. The conference’s aim was simple:
reduction of CO2 emissions, particularly in the construction sector, the role
of wood and forests for
the bio-economy and sustainable development. The
Conference attracted roughly 100 participants.
The members of the EU Parliament (Paul Brannen and Henna
Virkkunen, among others) highlighted the need for an increase of wood
products as building materials. “Wood
is the building material of the future -versatile, beautiful, and carbon
neutral”, they argued. However, wood production and processing has been a
key player in tackling climate change and developing a sustainable bio-economy.
The European sawmill industry, as part of the forest based
industry, provides a large number of employment opportunities and career
development in a wide range of occupations. Jobs are being created across the
skills spectrum and in a variety of business types and sizes – predominantly
the SME sector.
The sawmill industry is the backbone of the bio-economy.
Residues from sawmill processes can be converted into a broad range of
wood-based products including bio-composite materials, bio-plastics, textiles
and carbon-neutral biofuels. Simultaneously, the production of saw-logs, and
the correlated use of by products and residues, complies with the resource
efficiency principle, guarantees the highest profitability for forest owners
and provides the raw materials needed for developing the bio-economy.
Growing role of timber
Director for the environment at the French research centre (Gerard Deroubaix) offered a technical
explanation of the wood products as carbon store. He recalled that the carbon
footprint of construction products made of wood is, in a very large majority of
cases, significantly lower than the carbon footprint of the products made of
competing materials. He recalled that a recent study commissioned by the EU
Commission and entitled “Climwood2030” presented calculations at European level
showing that “the material use of wood products instead of functionally
equivalent alternative products leads to a decrease of fossil based GHG
emissions over the whole life cycle of about 1.5-3.5 t CO2 per ton of wood
product”.
The role of timber in architecture is great as well; some
participants (was Andrew Waugh)
showed the latest achievements of building with wood. For example, he presented
the Dalston Lane Project that has been the world’s largest CLT building: the
ten-storey, 121-unit development is made entirely of CLT, from the external,
party and core walls, through to the floors and stairs, weighing a fifth of a
concrete building of this size, and reducing the number of deliveries during
construction by 80%.

during construction by 80%. Another example of the wood application is the
Murray Grove. As explained by A. Waugh, the Murray Grove is the first urban
housing project to be constructed entirely from pre-fabricated solid timber,
from the load bearing walls and floor slabs to the stair and lift cores.
Per-Olof Weding,
President of European State Forest Association emphasised that European forests
are constantly growing both in size and in volume of wood. This extremely
positive fact is due to an active and sustainable forest management system that
ensures the production capacity and resilience of forest ecosystems as a whole.
He stressed that a vibrant European forestry sector can make
the bio-economy the next major economic development and can bring real benefits
to mitigate climate change.
Still questions to answer…
The
bio-economy is central to combating climate change and safeguarding ecosystems.
- What
services, technologies and industries in the forest-based sector are boosting
the bio-economy?
- How is
the bio-economy advancing the triple bottom-line of sustainability for society,
environment and business?
- How can
timber, wood-based products and other bio-based materials add value to the
durability of buildings and the resilience of cities while bringing down CO2
emissions?
- How to
make European urban construction/fabric more sustainable?
