Significant gapsPending Review

BYD is a rapidly scaling EV and battery manufacturer with critical transparency gaps. Absolute emissions have surged 5x since 2016 despite intensity-based targets. Scope 3 supply chain emissions remain entirely undisclosed, and recent controversies—including a 2022 pollution scandal dismissed as 'malicious fabrication' and 2025 slavery allegations in Brazil—reveal a company prioritizing growth over accountability.
