Greener Tech can also be appealing and fun. I’m really excited to see how CTL is turning positive impact into commercial and social value. I lead the commercial department for this great industry innovation, which means I connect to B2B tech users and their suppliers. Connect to me for questions on how the tech you use can be more aligned with your values - and why that is a smart thing to do.
