This practicum seeks to deepen understanding of how non-party stakeholders like businesses, banks, and investors engage on climate change under the Paris Agreement. It provides applied learning for Tuck students as they work with external project partners on the climate change Conference of Parties (COP) negotiations each year. The practicum explores how private sector voluntary pledges toward the Paris Agreement's 1.5C temperature goal complement the mandatory international commitments made by countries. These pledges began when the Paris Agreement was adopted in 2015 and have grown to more than 30,000 – with almost half from the private sector. As future business leaders, this practicum gives Tuck students an experiential learning opportunity in private sector climate action at the international level.
