About This Podcast

Zero Ambitions is a consultancy and weekly podcast about sustainability and the built environment. We find interesting and experienced guests who know what they're talking about, usually to discuss how we navigate the complexity of decarbonisation and sustainability in the built environment and its many related sectors. Hosted by Jeff Colley and Dan Hyde, publishers of Passive House Plus magazine (UK and Ireland), the podcast has now grow into a consultancy, Zero Ambitions Partners. The consultancy specialises in defensible sustainability communications. We create the strategy that makes built environment leaders stand out, enabling them to occupy positions that are distinct and defensible. As with the podcast itself, we help organisations to communicate about what they do and the value that they offer. Usually, this means strategies to change a conversation from price to value and how to futureproof an offer with evidence that makes its claims watertight. If you're a leader, or want to become one, we help you to make sense of where you stand in your sector, how to improve your positioning, how to communicate this to the market you operate in, and how to highlight the difference between you and your peer group. If you can engage your value chain by speaking about what matters to them, you can educate your key stakeholders and turn them into evangelists for your cause. Book a ‘ZAP Defensibility Audit’, but brace yourself - Uncover value and opportunities that you may  not have recognised - Find out if your sustainability claims are defensible - Find out if your claims are too meek - Change the conversation from price to value
