EU Commission I Targeted Consultation I 16 September 2026

Consultation on the ‘Do No Significant Harm’ Principle

The Commission has launched a targeted consultation on the envisaged approach to apply the ‘do no significant harm’ principle to the 2028-2034 Multiannual Financial Framework.
This consultation will help the Commission prepare a guidance on the application of the ‘Do No Significant Harm’ (DNSH) principle (by 2027).
The DNSH principle defines the environmental and climate conditions EU funds should apply. It means that EU money should not support activities that cause significant harm to the Union’s environmental and climate objectives.
The DNSH guidance aims to define a clearer, more predictable and more enforceable framework for applying this safeguard across the next Multiannual Financial Framework, replacing the current fragmented approach applied under the current budget.
In the Commission concept paper on the guidance, mechanical-biological treatment (MBT) plants for municipal waste and waste incineration plants (with exemptions) are listed as activities that could be considered to do significant harm to environmental objectives.

Deadline for feedback: 16 September 2026.
EU Commission | Written answer to MEP question

More information on the place of bio-based materials in future Circular Economy Policies

The EU Commission has responded to a question raised by Finish MEP Katri Kulmuni (Renew) regarding how bio-based materials and products will be taken into account in various EU policies.
In its answer, the Commission explains that several initiatives are intended to support the development of bio-based materials, including the Biotech Act II, the Circular Economy Act (both due by the end of the year), and dedicated work on bio-based plastics under the Packaging and Packaging Waste Regulation. It states that these initiatives will support the uptake of bio-based materials and improve the collection, treatment and use of bio-waste.
In addition, it advocates a technology- and material-neutral approach to the Ecodesign Regulation, and notes that environmental footprint methods are being revised to take into account the differences between bio-based and fossil materials, such as carbon uptake.

ECN Task Group Quality Assurance I 8 July 2026

Discussion on monitoring approaches of potential hazards in Input Materials for Biological Treatment

On 8 July, leading quality managers from compost and digestate quality assurance organisations across Europe met at Vlaco’s office in Mechelen, Belgium, to discuss potential contaminant levels in input materials for composting and anaerobic digestion.
Three presentations were given to demonstrate how different national quality assurance organisations monitor contaminants in materials entering composting and anaerobic digestion plants. The different approaches to monitoring were discussed, and the analysis results demonstrated that an indicative positive list for input materials for composting and anaerobic digestion would be the most effective way to prevent the dilution and contamination of the final compost and digestate products.
In addition, Stefanie Siebert, the Quality Manager of ECN, presented the revision of the quality manual of the European Quality Assurance Scheme ‘ECN-QAS’.
This has been updated in relation to the limit values for different impurities (glass, metal, and plastics) in the Fertilising Products Regulation (Regulation (EU) 2019/1009), as well as the European analytical standards under the standardisation mandate M/564 that are due to be officially published in 2027.

Soils for Europe Conference I 7–11 September 2026 I Coimbra (PT)

ECN Presents Long-Term Benefits of Compost for Soil Health

ECN will contribute to the Soils for Europe conference in Coimbra, Portugal, from 7 to 11 September 2026. Co-organised by several Mission Soil projects, the event brings together researchers, policymakers, land managers and other stakeholders to showcase European research and innovation for healthy and resilient soils.
Olivier Labrie, ECN Project Officer for Agriculture, will present “Quantifying the Long-Term Agronomic and Economic Benefits of Compost: Soil Health, Nutrient Supply, and Fertiliser Reduction” in Session 9.1 on 9 September. Drawing on long-term compost trials and ECN’s 2026 Fact Sheets, the presentation will highlight compost’s potential to help reverse soil degradation, with 62% of EU soils currently considered unhealthy.
The presentation will underline the importance of taking a long-term perspective when assessing compost for soil health and farm resilience to climate change. It will focus on organic matter and carbon as key drivers of soil functionality and nutrient provision, and on how greater valorisation of bio-waste into compost could help reduce farm vulnerability and stabilise yields under increasing climate stress.

LIPOR Seminar I 25 September 2026

The future of Climate-Resilient Urban Gardening

How can urban gardens adapt to hotter and drier conditions? Which crops are best suited to a changing climate, and how can gardens contribute to more resilient communities?
These questions will be at the heart of “My Garden in Tomorrow’s Climate”, a seminar organised by LIPOR on 25 September at Casa do Corim – The Place of Sustainability. From 8:45 am to 1:00 pm, gardeners and municipal technicians will come together to share knowledge, experiences and practical solutions for adapting urban agriculture to climate change.
The programme will explore key aspects of climate-resilient gardening, from healthy soils and water management to drought- and heat-resistant crops. Sessions will include “Healthy Soil, Happy Garden”, led by Pedro Nogueira from CIBIO, a presentation on resilient horticultural varieties by agricultural scientist Rosa Moreira, and a practical exchange of experiences featuring the gardens of Famalicão Municipality.
The morning will conclude with the round table “Roots in Conversation”, bringing together the speakers to discuss the challenges and opportunities facing urban gardens in a changing climate.
Through this initiative, LIPOR aims to connect technical knowledge with the practical experience of gardeners and highlight the role of urban gardens in promoting biodiversity, healthy soils, responsible resource use, composting and stronger communities.
