Regional climate change policies: An analysis of commitments, policy instruments and targets

Regional governments represent an increasingly relevant component in climate change policies, which showcase a high interest in the climate change sphere and provide several benefits connected with their governance. This study aims to shed light on this scale of governance by describing the climate change policies of 61 regions from all over the world and by analysing the possible connections between the regional environmental policy instruments and the level of mitigation and adaptation commitment. The results show that the regional governments of this work appear to be an active component in climate policy, since they all have their own GHG emission reduction targets, devise their own climate policies and instruments and participate in international climate networks. All regions have reported mitigation and adaptation commitments, with different levels of ambition. In addition, it is observable that while some regions (mainly the North) focus mostly on mitigation targets, other (the South) focus on adaptation. Finally, there does not seem to be a connection between the level of climate commitment and the preference for some policy instruments. © 2020 FrancoAngeli

Climate change induced socio-economic tipping points: review and stakeholder consultation for policy relevant research

Tipping points have become a key concept in research on climate change, indicating points of abrupt transition in biophysical systems as well as transformative changes in adaptation and mitigation strategies. However, the potential existence of tipping points in socio-economic systems has remained underexplored, whereas they might be highly policy relevant. This paper describes characteristics of climate change induced socio-economic tipping points (SETPs) to guide future research on SETPS to inform climate policy. We review existing literature to create a tipping point typology and to derive the following SETP definition: a climate change induced, abrupt change of a socio-economic system, into a new, fundamentally different state. Through stakeholder consultation, we identify 22 candidate SETP examples with policy relevance for Europe. Three of these are described in higher detail to identify their tipping point characteristics (stable states, mechanisms and abrupt change): the collapse of winter sports tourism, farmland abandonment and sea-level rise-induced migration. We find that stakeholder perceptions play an important role in describing SETPs. The role of climate drivers is difficult to isolate from other drivers because of complex interplays with socio-economic factors. In some cases, the rate of change rather than the magnitude of change causes a tipping point. The clearest SETPs are found on small system scales. On a national to continental scale, SETPs are less obvious because they are difficult to separate from their associated economic substitution effects and policy response. Some proposed adaptation measures are so transformative that their implementations can be considered an SETP in terms of 'response to climate change'. Future research can focus on identification and impact analysis of tipping points using stylized models, on the exceedance of stakeholder-defined critical thresholds in the RCP/SSP space and on the macro-economic impacts of new system states
