気候目標の厳格化に伴い、社会技術的な転換点(ティッピングポイント)が注目されています。ドイツの持続可能性研究所の研究によれば、電気自動車と太陽光発電の導入を例に、これらの転換点は予測可能であり、政策決定者が適切な対応を取ることができるとされています。電気自動車市場はまだ転換点に達していませんが、太陽光発電分野はポジティブな進展を見せています。今後、電力網の拡大などが転換点への鍵となるとしています。

ポジティブな変化の指標としての転換点(Tipping Points as Indicators of Positive Change)

Highlights

  • Socio-technical tipping can be anticipated when evaluated across subsystems.
  • Electric vehicle and solar PV transitions show different proximities to tipping.
  • Technology system has greatest potential to tip rapidly.
  • Technology progress is significant but represents only one facet for a system to tip.

Abstract

The tipping point concept, widely recognized within the natural sciences, is experiencing a resurgence in social studies. The emerging field sees growing insights about characteristics and mechanisms of social system tipping; however, much disagreement remains. This includes whether social tipping points can be anticipated – determining its political relevance, as anticipation is essential for actions to intentionally trigger tipping. We address this disagreement and propose a framework which operationalises socio-technical tipping across subsystems and elements to anticipate tipping points, illustrated in two case comparisons. We show that whereas the transition to electric cars in Germany has started but is not about to tip, especially not regarding normative and regulatory regime factors, the same transition in Norway is about to tip, but still requires international car markets to tip before the sectoral transition is tipped and complete. Similarly, we show that the transition to a PV-based renewable power system in Germany has progressed strongly, both regarding technology and regime factors, but the system has not yet tipped: further efforts reforming infrastructure and regulation are essential. Hence, our findings emphasise the notion that while technological progress holds significance, it represents only one facet among several that must align for a system to undergo a tipping point.
