Sustainable by Every Measure

At the Westin Michigan Avenue Chicago, we’re committed to eco-friendly and sustainable practices in every corner of our hotel, so you can feel good about meeting here, and staying here. Recent renovations allowed us to replace wall board, ceiling tile, carpeting, lighting, and more with recycled and low-energy alternatives. Our beautiful new doors were crafted from wood that meets criteria for forest stewardship. Speaking of trees, our “Clutter Free Meetings” initiative and paperless sales and inventory system dramatically reduce our paper use. We monitor our water use, waste management, and food choices to support sustainability efforts. In our kitchen, too, we embrace a no-waste approach to food and curate our ingredients from local farms with sustainable practices. We’re thoughtful about how we can support the environment, because we want the environment to continue supporting us, and you.
