How do we make our software greener? While at NDC in Porto, Carl and Richard talked to Lea Mladineo about her work in sustainable development. Lea talks about the impact of digital technology on the environment and how, with some thought and effort, we can make a real difference to that impact. The conversation explores how cloud computing can worsen the problem - or better!
