Climatic change: CD-Links special issue on national low-carbon development pathways

Abstract

One hundred and ninety-three governments adopted the Paris Agreement on Climate Change in 2015. The agreement foresees, for the near term, a new bottom-up process where countries pledge so-called nationally determined contributions (NDCs) for reducing their greenhouse gas (GHG) emissions by 2025–2030. At the same time, the Paris Agreement defines the longterm objective to hold temperature change to well below 2 °C and to pursue efforts to limit it further to 1.5 °C. The consistency between the NDCs and the long-term temperature goals is planned to be regularly assessed in global stocktaking exercises as part of the international negotiations. At the same time, countries have also committed themselves to implement a set of Sustainable Development Goals (SDGs) in order to eradicate poverty, protect the global environment and spur inclusive economic development. Within this context, the CD-LINKS project (www.cd-links.org) brought together an international team of researchers with global, national and sectoral expertise to explore possible linkages between national and global pathways consistent with the overall objective of the Paris Agreement and sustainable development. Part of this work is summarised in this special issue in Climatic Change, which contains eleven papers, including this introductory one, presenting the insights from the collaboration between national and global modelling teams and yielding a more coherent and detailed picture of the future than is typical of climate change mitigation pathways studies focusing on the global level only.
