By setting standards and regulations for emissions levels, pollution controls, and renewable energy adoption, regulatory policies can effectively drive systemic changes to reduce greenhouse gas emissions. Additionally, regulatory policies can potentially yield more equitable outcomes by imposing standards uniformly across industries and ensuring that all
