How can political polarization be overcome to solve important sustainability issues?

Political polarization, or the inclination to align with the identity, ideologies, and candidates of a party that results in subsequent partisan animosity that creates divisions between these groups, can prevent important policies from getting passed. Policies related to sustainability, defined as that which “meets the needs of the present without compromising the ability of future generations to meet their own needs,” have been found to be particularly vulnerable to polarization (Brundtland, 1987). This research analyzes literature and expert interviews to provide recommendations and strategies that can be employed by sustainability advocates to get important policies passed despite the divisive political arena. The research concluded that public salience of sustainability issues, presentation of the co-benefits of sustainability policies, relationships amongst elected officials, and use of politically neutral language are especially important to garnering bipartisan support for sustainability policies. Based on these conclusions, strategies were recommended for sustainability advocates to use to overcome political polarization including bolstering communication skills to demonstrate how people are affected by sustainability issues and can benefit from sustainability policies and giving careful and continuous consideration to the words, phrases, and labels used to describe sustainability policies. A final recommendation is to examine political polarization and sustainability at the municipal level since this research indicated that this is a relatively under-examined context.
