Nancy's Final Five Question Responses:

What is one piece of advice you would give other sustainability professionals that might help them in their careers?

Schedule out your own personal sustainability because it could be an easy burnout field. That's probably my first and foremost recommendation.

What are you most excited about right now in the world of sustainability?

I'm excited to see the light bulb go off in the CEO's heads. We're seeing that frequently and across our client base now. That's exciting because when that happens, we know that we've done our job well and we know that the market's moving in the right direction. We know that humanity is moving in the right direction.

What is one book you would recommend sustainability professionals read?

I have a lot right now because I'm also teaching for a few universities. Strangely enough, it's not necessarily sustainability-driven. It's a series on building business models, and that's The Business Model Navigator Set. There's one on value proposition, there's a business model generator and then the original business model navigator. So, I would highly recommend those because it's a very easy read and quick resource that helps bridge the gap between sustainability being a nice-to-have to something that's operationalized.

What are some of your favorite resources or tools that really help you in your work?

Google docs is a great one. Our team loves working within Google docs, and with our clients we can quickly add notes and work on things together in the same system even though we're in different parts of the world. It really expedites our work.
