Lola Vallejo participated in this webinar organised by the European Chair for Sustainable Development of PSIA and School of Public Affairs at Sciences Po, and by SIPA and Earth Institute/Climate School at Columbia University.

The Paris Agreement aims to limit global warming well below 2 degree Celsius, and preferably to 1.5 degree Celsius, compared to pre-industrial levels. A recent estimate suggests that net zero commitments by governments cover 60% of global greenhouse emissions, 68% of the global economy and over 50% of the global population. Targets are important to marshal action; they are the means to an end. However, a paucity of immediate action and focus of governments (and of companies) on distant targets suggests a real danger of targets becoming ends in themselves. 

In this roundtable the speakers debated ideas on the pragmatics of marshalling action to meet socially inclusive net zero global emission by 2050. In what ways can targets be usefully employed? What should be the nature of planning and of instruments including market mechanisms, industrial policies and tariffs? What forms of coalitions, respecting the principle of common but differentiated responsibilities and respective capabilities, would yield the most progress? What are some ways of leveraging differing political economies, governance forms and development unevenness to limit global warming?
