WWF and Quantis have launched a free biogenic carbon footprint calculator to measure emissions from forest-based products.

Takeaways

WWF and Quantis have launched a free biogenic carbon footprint calculator to help companies measure emissions from wood-based products.
The tool supports dynamic accounting of biogenic carbon and improves greenhouse gas (GHG) inventory accuracy.
It aims to promote sustainable sourcing and better decision-making for forest-based industries.

The World Wide Fund for Nature (WWF), in partnership with Quantis International, has introduced a free and user-friendly biogenic carbon footprint calculator designed to measure emissions from a wide range of forest-based products. This innovative tool enables companies to assess the biogenic emissions of wood-based materials, helping them improve the accuracy of their greenhouse gas (GHG) inventories and make informed decisions about sustainable sourcing, design, and product use.

Currently in its beta phase, the calculator will be updated and refined based on user feedback and alignment with forthcoming Greenhouse Gas Protocol guidance.

Wide Application Across Forest-Based Products

The new calculator can be applied to an extensive list of forest-based products, including bioenergy pellets, paper, and timber, and their various end uses, such as renewable energy generation, furniture manufacturing, and pulp and paper production.

It provides reference values for different forest types, tree species, and product life spans, for instance, less than one year for energy pellets and up to 15 years for wooden furniture. Users can also customize the tool using location- or company-specific data for more accurate results.

Comprehensive instructions are available through a quick start guide and user manual, making it easy for organizations to begin using the calculator effectively.

Dynamic Accounting Methodology

Unlike traditional static accounting methods, the biogenic carbon footprint calculator uses a dynamic accounting approach that factors in how carbon flows over time. This approach relies on time-dependent characterization factors that assess both emissions and carbon removals each year.

The tool expands on the concept of the global warming potential of biogenic carbon (GWPbio), which accounts for carbon gaps, the temporary reduction in forest carbon stocks before regrowth, and the climate benefits of storing carbon in wood products.

Its methodology covers several key carbon pools:

Above-ground biomass (AGB)
Below-ground biomass (BGB)
Dead organic matter (DOM)
Soil organic carbon (SOC)

Results are provided in kilograms of CO₂ equivalent (kg CO₂e), offering a standardized way to compare emissions and removals.

Focus on Biogenic Emissions

While the calculator focuses specifically on biogenic carbon emissions, it does not account for other environmental aspects of forest biomass use, such as biodiversity, water use, or socioeconomic factors. Nonetheless, it represents an important step toward standardized and transparent reporting of biogenic carbon in forest-based industries, supporting more credible and science-based climate action strategies.
