How can we develop and further improve life cycle impact assessment methods, characterisation factors and normalisation factors?

A critical look at the impact assessment modelling of metals in Life Cycle Impact Assessment and improvement options.

The ReCiPe methodology for Life Cycle Impact Assessment (LCIA).

CML-IA is a database that contains characterisation factors for life cycle impact assessment (LCIA) and is easily read by the CMLCA software program.

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

The project falls in the context of the EU Thematic Strategy on the Sustainable Use of Natural Resources (COM(2005)670). The Institute for Environment and Resources (IES) of the Joint Research Centre (JRC) has developed three sets of decoupling indicators. Such indicators require the definition of a…

Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Hoe kunnen we onze maatschappij zo inrichten dat de wereld leefbaar blijft voor onszelf en al het andere leven om ons heen? Aan dat vraagstuk werken Leidse wetenschappers samen vanuit allerlei disciplines, van biologie tot datawetenschap en van milieueconomie tot archeologie.

Are there significant differences among the environmental impacts resulting form the production of Asian aquaculture commodities and what are the main causes for these?

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

Promotor: Prof.dr. G.R. de Snoo

What performance criteria does a new technology have to fulfill in order to be added to the list of future energy options and what constraints exist in terms of broad market penetration?

What are the life-cycle environmental impacts and risks to human health and ecosystems of a III-V/Si PV system? How can these be expected to change when the system is deployed at industrial scale? What are the most favourable recycling scenarios?

How to bring together different footprints into an integrated family and what are the synergies? What are the roles of inventory analysis and characterization in measuring individual footprints and how these affect a footprint family? How to benchmark environmental footprints against related planetary…

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

What are the environmental trade-offs for SMEs considering moving from monoculture aquaculture practice towards IMTA? What are the environmental trade-offs comparing IMTA species with their conventional monoculture alternatives?

Possible improvements for the assessment of abiotic depletion in LCA.

What is the role of the rebound effect in achieving environmental savings from transport eco-innovation? Are traditional definitions of the rebound effect adequate in the context of transformative innovations and multidimensional environmental issues?
