Waisman, H., de Coninck, H., Rogelj, J. (2019). Key technological enablers for ambitious climate goalsInsights from the IPCC Special Report on Global Warming of 1.5°C. Environmental Research Letters in press.
The Special Report on Global Warming of 1.5°C (SR1.5) by the Intergovernmental Panel on Climate Change (IPCC) shows that achieving greenhouse gas (GHG) emission reductions that can limit warming to 1.5°C requires rapid and far-reaching transitions in energy, land and ecosystems, urban and infrastructure and industry systems. Three layers of assessment underpin the report's insights in technological enablers of these transitions: global technology pathways emerging from techno-economic global modelling, feasibility assessment of various technology options along economic, technological, institutional, socio-cultural, environmental and geophysical dimensions, and evaluation of synergies and trade-offs between different mitigation options and sustainable development goals. This paper identifies and discusses eight robust messages emerging from the report regarding the technological enablers for limiting global warming to 1.5°C in the context of sustainable development.
