HoliSoils supports key stakeholders with science and tools for GHG reporting

Experts from the Land Use, Land Use Change and Forestry (LULUCF) sector are one of HoliSoils’ main target stakeholders. The LULUCF group at the Joint Research Centre (JRC) Bioeconomy Unit provides science-based support to the European Commission’s services in understanding how forests mitigate and interact with climate change in the context of EU and international climate policies. Many of the results developed in HoliSoils are directly targeted to these experts and HoliSoils has established a good and regular dialogue with the group, not least through Anu Korosuo who represents JRC on the HoliSoils Stakeholder and End-User Advisory Board (SEAB).

Partners from the HoliSoils project were invited to present the project and its results so far at the 2023 JRC LULUCF workshop, held in May. The main purpose of these meetings is to provide understanding on how LULUCF regulation is interpreted and of the methods used by different member states for their GHG inventories. The May workshop focused on the needs and opportunities to enhance LULUCF reporting to support climate change mitigation targets for 2030 and beyond.

Aleksi Lehtonen (Luke) presented the HoliSoils project while Mart-Jan Schelhaas (WUR) presented on EFISCEN-Space, the high-resolution forest resource model being updated as part of the project. Hans Verkerk (EFI), also a partner in HoliSoils, presented the ForestPaths project, of which he is coordinator. HoliSoils is working with ForestPaths and other relevant EU-funded projects to ensure synergies between activities and avoid duplicating efforts.

The LULUCF workshop combined overview sessions on the state-of-art of the GHG inventories and the revised LULUCF regulation. Specific sessions focused on moving to higher Tiers in reporting, and on the use of geographically-explicit data and new advances in remote sensing in GHG inventories.

Interesting for HoliSoils is that countries will need to improve their GHG inventory methods in the near future. While many countries do well with forest biomass reporting, there is room for improvement: most countries use Tier 1 but will need to move to Tier 2 by 2028. HoliSoils is providing tools to support such a transition, with a model ensemble tool currently in a beta phase and soon to be launched. Also of interest is the HoliSoils peat map (and other maps) under development, which will support spatially explicit reporting and improve land-use change estimates by providing soil data, contributing to the reporting needed for biodiversity and emission hot-spots.
