missions reduction treaties between nations have been proposed as a key method with which to tackle climate change and its negative impacts. One such treaty is the Paris Agreement. Adopted by 197 nations in 2015, the deal aims to substantially reduce carbon emissions and to limit the global temperature increase in this century to 2 degrees Celsius. A summary of the Paris Agreement can be found here. The Paris Agreement includes commitments from all nations to reduce their emissions and work together to adapt to the impacts of climate change and calls on a strengthening of commitments over time. The agreement provides a pathway for developed nations to assist developing nations in their climate mitigation and adaptation efforts. Nations can set their own nationally determined contributions towards emissions reductions that reflect their capabilities, level of economic development, and contribution to emissions over time.
