Boston can become a global climate justice leader by embracing radical possibilities that prioritize systemic change. A Green New Deal for Boston can address the root causes of issues such as affordability, congestion, and unequal access to city resources. The Boston Green New Deal recommends seven main principles for systemic change rooted in transformation and accountability. It calls for changes that are people-centered, rights-based, and democratic. These changes must demand the prioritization of justice, decommodify society and nature, and provide social and ecological resilience. Initiating concrete policy proposals that align with these principles will help Boston recover from the pandemic in a way that ensures community resilience and promises residents secure jobs, affordable housing, and a thriving local economy.
