The OpenCO2 emissions database is one of the most comprehensive emissions databases in Europe. Our experts select and validate all emission factors added to the OpenCO2 database and keep them up to date.

By creating a free account on the OpenCO2net platform, you can view approximately 1,200 emission factors with background information. If you would like to use all of our approximately 8,000 emission factors, please contact us or purchase OpenCO2net subscription.

Background of emission factor

The emission factor for plywood indicates the carbon dioxide equivalent emissions per cubic meter of production. It is influenced by factors such as raw material sourcing, the energy sources used in manufacturing, and transport distances.

Emission factor category

A product’s emission factor indicates either life cycle emissions (cradle-to-grave) or emissions from production (cradle-to-gate). The correct emission factor depends on the type of calculation being made. Cradle-to-grave is commonly used for consumer products, while cradle-to-gate is often more practical for business-to-business cases, especially for raw materials. The cradle-to-gate emission factor is, for example, applied in industrial companies’ scope 3 calculations when assessing emissions from raw material purchasing. A product’s carbon footprint also often includes only the cradle-to-gate stages, in which case it is referred to as a partial carbon footprint.

More information Density 680 kg/m3. Density 680 kg/m3, moisture content 8%. Plywood is made from thin wood veneers by gluing. The thickness of an individual veneer is between 0.2 and 3.2 mm. There is usually an odd number of veneers in birch plywood (at least three). The adhesive is usually weather- and boil-resistant phenol formaldehyde resin. There are several EPDs available for plywood products manufactured in the Nordic countries. However, some of the results are outdated and are being currently recalculated. Proposal for uncoated birch plywood is an average calculated based on the values given in EPDs by Koskisen and MetsäWood.Standard used: EN 13986+A1 Wood-based panels for use in construction. Characteristics, evaluation of conformity and marking . Database version: 1.01.001. This emission factor updated in CO2data database in 2023-06-29.

Quality of emission factor

5 star5 star5 star5 star5 star

High-quality emission factors verified by an external verifier, usually sourced directly from the supplier (primary data). The factor may be a maximum of 3-5 years old and cover all greenhouse gases (CO2e).

4 star4 star4 star4 star4 star

Unverified primary data factors, as well as new and accurate average factors based on physical quantities. The factor may be a maximum of 3-5 years old.

3 star3 star3 star3 star3 star

Average, based on physical quantities, with one of the following shortcomings: more than 5 years old, only CO2 emissions, or contains many assumptions.

2 star2 star2 star2 star2 star

Inaccurate emission factors based on physical quantities that contain several of the following shortcomings: more than 5 years old, only CO2, or contains many assumptions. The newest, highest-quality spend-based emission coefficients also fall into this category.

1 star1 star1 star1 star1 star

Old and inaccurate spend-based emission factors. Their use in emission calculations should be avoided.
