What requirement must projects meet to be classified as sustainable on Alibaba's platform?

To classify projects as sustainable on Alibaba's platform, one crucial requirement is that they must be backed by investors on the "Blue Map" platform. This platform is designed to promote and track investments in environmentally friendly projects, thus ensuring that the projects align with sustainability goals. By being backed on this platform, projects demonstrate a commitment to sustainable practices and accountability, thereby reinforcing their credibility and impact within the sustainability sector.

Projects lacking this backing may not have the necessary support or validation that aligns them with Alibaba's sustainability standards. While government approval, inclusion of renewable energy sources, and adherence to safety standards can contribute to a project's sustainability, the specific association with the "Blue Map" platform is what distinctly connects a project to Alibaba's sustainability criteria. This highlights an emphasis on funding sources that prioritize eco-conscious initiatives.
