Nina Dar. The Change Troubleshooter
Change doesn’t only happen on big stages or inside shiny transformation programmes.
It happens in real lives, real communities and often far from the spotlight.
Nina Dar: The Change Troubleshooter is a podcast that gives space to those stories.
Hosted by Nina Dar, transformation leader, executive coach and founder of Cheeky Monkey Business Solutions, the podcast features conversations with people who’ve driven change from the grassroots up, challenged the status quo, or quietly shaped the world in ways you may never have heard of, but should.
Some episodes are planned. Some are wonderfully accidental. All are real.
In 2026, the podcast leans into the themes of Nina’s book,
Your Move: The Human Reset 100 Coaching Moments for Conscious Transformation in the Age of AI, exploring what it really means to stay human, awake and courageous in a world accelerating faster than our systems, and sometimes our thinking.
No hype. No hero worship.
Just honest stories, human insight and the belief that real change starts closer to the ground than we’re usually told.

Can we be Sustainable with or without Data?
Welcome to season 2 of The Change Troubleshooter, the sustainability season.
In today’s episode, Can We Be Sustainable With or Without Data? Nina is joined by
Federico Pettinella, Anders Praestholm and Alan Walker, three guys who work in data technology.
Every time we write an email, take a photo, download something from the web or send a message on Whatsapp, we are creating data. The amount of that data is massiveand growing quickly.
Business and industry create even more data than individuals and it all has to be stored somewhere. This accumulation and storage of data is not free, it comes at a cost, and not just a financial cost – the cost to the environment is considerable as stored data requires massive amounts of energy to keep all those computers running.
Our ability to analyse data is essential to good decision making, it’s how we know we have climate change issues but creating and storing too much data make decision making difficult. How do we find the right balance of quality of data, over quantity?
