Häyhä’s research interests include exploring challenges of human development and global environmental sustainability. Her current research focuses on developing approaches for operationalising the planetary boundaries framework at sub-global scales and for different sectors.
Recently, she worked in a project commissioned by the European Environment Agency and the Environment Knowledge Community to improve understanding of planetary boundaries and a safe operating space at the European Union level.
In collaboration with Ellen MacArthur Foundation, she studies how circular economy can help deal with global environmental issues, with a particular focus on textile industry.
Her other research activities, together with PBL Netherlands Environmental Assessment Agency, investigates global energy pathways in the context of UN’s Sustainable Development Goals. The project assesses quantitatively the role of the energy sector in a broad set of global environmental change and human development issues.
Häyhä holds a PhD in Environment, Resources, and Sustainable Development from Parthenope University of Naples, Italy. She has a background in environmental and ecological economics, environmental assessment, energy, and ecosystem services.
She is involved in a number of international networks, including Planetary Boundaries Research Network (PB.net), Future Earth Fellows, and IIASA Alumni Association.

2019 - Journal / article
Background : The Planetary Boundaries concept (PBc) has emerged as a key global sustainability concept in international sustainable development arenas. Initially presented as an agenda for global sustainability research, it now shows potential for sustainability governance. We use the fact that it is widely cited in scientific literature (>3500 citations) and an extensively studied concept to analyse how it has been used and...

A rapidly growing share of global agricultural areas is devoted to the production of biomass for non-food purposes. The expanding non-food bioeconomy can have far-reaching social and ecological implications; yet, the non-food sector has attained little attention in land footprint studies. This paper provides the first assessment of the global cropland footprint of non-food products of the European Union (EU), a globally import...

This study has made an initial disaggregation, allocation and benchmarking analysis to the EU-28 level, for the planetary boundaries for climate change, biosphere integrity, land systems change, freshwater use, biogeochemical flows (nitrogen and phosphorus), and novel entities (chemical pollution). The following overarching insights relate to all PBs: Based on equal-per capita allocation of the global safe operating space, ...
