Abstract Human-driven freshwater change relates to elevated Earth system risks, which motivates analysis to better understand its global characteristics. Here, we analyse global and regional patterns of anomalous conditions and their drivers in streamflow (blue water) and soil moisture (green water), building on the recently updated planetary boundary for freshwater change (PB-FW).

Abstract Cities and companies have great potential to reduce pressures on Earth system boundaries. Science-based target setting has emerged as a powerful tool to help achieve the potential, but its uptake has been limited. Moreover, cities and companies usually develop their targets separately, even though many are co-located. Focusing on the top 200 cities and 500 companies by greenhouse gas emissions, we analyse the current state and potential of adopting science-based targets for climate.

Abstract Operating within safe and just Earth system boundaries requires mobilizing key actors across scale to set targets and take actions accordingly. Robust, transparent and fair cross-scale translation methods are essential to help navigate through the multiple steps of scientific and normative judgements in translation, with clear awareness of associated assumptions, bias and uncertainties.
