Multi-level assessment of Bio-based Negative Emission Technologies - Sub-project 3: Forestry and Silviculture

Climate neutrality is an important long-term goal of climate policy. It requires bringing emissions of greenhouse gases at least into balance with their uptake in sinks. How can forests and forestry contribute to this goal?

Background and Objective

Technologies and concepts for CO2 capture using biomass (biobased negative emission technologies, or NETs for short) are a central element of net-zero policy strategies. They are embedded in agricultural and forestry value chains, can be implemented in a variety of ways and compete with the provision of materials and energy. However, these concepts have not yet been realised and are characterised by various risks in terms of feasibility and market introduction, among other things because a holistic evaluation that takes local and regional conditions into account has been lacking up to now.

This is where the BioNET project (Multi-level assessment of biobased NETs) comes in and provides a problem-adequate knowledge base for the assessment of biobased NETs in Germany. New social science approaches are combined with established methods of modelling competition for limited biomass, and trade-off analyses. For this purpose, a three-stage approach will be developed:
(1) provision of a transparent and easily accessible database on biobased NETs,
(2) new participatory approaches to explore societal and institutional feasibility, and
(3) development and holistic assessment of national scenarios for biobased NETs taking into account the Sustainable Development Goals (SDGs).

This is to achieve understanding of and confidence in the concepts and processes, and to use stakeholder mobilisation in all project phases to identify and overcome barriers. As a result, possibilities for action for bio-based NETs should be communicated in an adapted manner and political and other decision-makers at different scales, but also scientists, should be empowered to take these appropriately into account in their work and decisions.

Approach

The Thünen Institute for Forestry contributes to the overall project by providing the forestry/ silvicultural NET concepts:

  1. In the first step, different silvicultural management options at stand level and their short-, medium- and long-term effects on carbon stocks and substitution potentials are qualitatively presented, taking into account the respective production risks. The product is a set of indicators of which silvicultural management options can contribute to emission reductions for a given baseline condition.
  2. Based on this, the individual silvicultural elements are compiled and quantified into strategies coordinated over the lifetime of the stand; this also includes estimating the impacts on costs, yields and values of environmental services. The products are fact sheets on the emissions balance in the individual scenarios over time and their impacts on the yield situation and value of environmental services, as well as a literature review on forestry options for improving the emissions balance.
  3. Finally, the previously developed strategies are synthesised into scenarios that fit into the baseline conditions in three focus regions. Product are scorecards that inform about regional climate protection and adaptation potentials in the forest, and their economic and socio-ecological consequences.

In addition, we support the project partners in the preparation and implementation of relevant workshops as well as in the development of national NET scenarios and their technical-economic modelling.
