Background: In 2015, one of the largest healthcare companies in the world committed to phasing out from all its products and processes worldwide any substances declared by the European Chemicals Agency to be of very high concern. Since then, extended practical experience was gained in the phasing out of substances of concern. Results: We report in detail on a company-wide programme to phase out substances of concern, the challenges of and the approaches to the phase-out. The paper provides concrete ideas of how to address the legitimate urge to remove substances of concern from economic activities in a holistic way, taking into account the broad diversity of aspects of sustainability. The present paper also reviews the regulatory and societal environment in which substances of concern are being phased out. The paper attempts to contribute to the ongoing discussion of how to improve the chemicals policy in Europe and beyond. Conclusions: Phasing out substances of concern, substance selection for new products and processes, and the avoidance of regrettable substitutions while maintaining the pace of genuine innovation will stay a major challenge for our industry in the years ahead whereby not only toxicological and ecotoxicological hazards have to be considered in the selection and deselection of substances, but also other sustainability criteria characterising the entire life cycle will play an increasingly important role. Legislators and industry need to pay more attention to how this is implemented while avoiding slowing down innovation, making essential products unnecessarily more expensive, and further pushing material production out of highly regulated countries.

Hydropower has played an important role in Europe in recent decades, offering a unique combination of safe, low-cost, and clean power generation. Today, it is still one of the largest renewable energy sources (RES), accounting for about 35 % of RES electricity generation. However, grid stability is threatened by the increasing amount of undispatchable RES. Flexibility and dynamics such as energy storage and rapid response are urgently needed to achieve EU policy goals. In such a context, hydropower can play a key role, not only as a provider of regulated renewable energy but also due to its ability to balance a renewable energy system in the short term and the medium/long term by pumped storage technology. All these aspects underline the new role of hydropower, which aims to strengthen grid stability and power supply resilience and to enable higher penetration of volatile RES. In this context, the aim of this paper is to demonstrate the role of hydropower at the European level as well as the needs and opportunities of modernization to fully exploit its potential. In particular, this study provides, the assessment of the today flexibility offered by hydropower to the power system at the European level by leveraging a database of information collected through the participants to the working groups of the COST Action Pen@Hydropower which includes stakeholders in the hydropower sector of 34 European countries. The study confirms the key role of hydropower in future energy scenarios with 30 % of the flexibility demand at all time scales met by hydropower. Furthermore, the paper presents a review of the digitalization solutions and innovative technologies that support the growth of a new generation of sustainable hydropower together with the modernization opportunities for existing hydropower plants. The results of this work have practical implications for stakeholders in the hydropower sector and policymakers as it provides evidence at the European scale of the role of hydropower technology in balancing the power system and the need to have supportive frameworks and adequate markets to fully exploit the European hydropower potential to achieve the energy transition goals.

• An approach for identifying and selecting sustainability indicators for assessing technologies at low TRL. • Three distinct screening tools – a framework, a questionnaire for actor priorities, and a list of indicator selection criteria – are developed and employed to select indicators. • From an initial pool of 382 indicators, the study narrows down to a set of 26 representative indicators deemed essential for assessing the considered system at its early stages. • The new approach outlined in the paper is found to be practical to implement and time- and resource-efficient, when no standard set of indicators exists. In Europe, a decrease in the availability of phosphate rock resources has led to the development of emerging technologies for phosphorus recovery, with the purpose of generating products that can be used as fertilisers. An innovative conceptual system dedicated to the phosphorus recovery from dairy wastewater is considered in the paper. New technologies need to be assessed using relevant sustainability indicators. In this study, we developed an approach for identifying and selecting indicators. Based on searches of literature and expert interviews, three different tools were developed: an indicator screening framework, a questionnaire for finding actor priorities, and a list of indicator selection criteria. The new approach was successfully used to narrow down an initial set of 382 indicators identified in the literature to 26 that were considered representative and practicable for the assessment of the considered system.

Climate-smart agriculture (CSA) is one response to the challenges faced by agriculture due to climate change. As with other sustainability transitions, technological innovation is highlighted as playing a critical role, however, the adoption and diffusion of technological innovations in OECD countries is slow. The aim of this paper is to identify key socio-economic barriers, in terms of supply and demand, that inhibit the adoption and diffusion of CSA technological innovations in Europe. To achieve this aim, a theoretical framework is constructed based on a literature review of socio-economic barriers effecting adoption and diffusion. This framework is explored with data from semi-structured interviews with CSA technology providers and members of agricultural supply chains, such as farmers associations and consumer goods producers (the end-users of the technology). Data was collected on the barriers they experienced, with interviews conducted in the Netherlands, France, Switzerland and Italy. This data was thematically coded and categorised to identify key barrier typologies. The results demonstrate that barriers exist on both the demand (user) and supply (technology provider) sides. The paper provides recommendations for increasing the adoption and diffusion of CSA technological innovations, as well as implications for the CSA and innovation literature. [ABSTRACT FROM AUTHOR]
