Sustainable development promotes a clean environment. This is because the main goal of sustainable development is to create an equilibrium between our current needs and the needs of future generations. This involves using resources wisely, reducing waste and pollution, and promoting conservation efforts. Therefore, sustainable development does not promote pollution or unhygienic conditions, as these would harm the environment and deplete resources. So, the correct answer is "Clean environment".
