Environment Variables

Chris Skipper hosts Florent Morel and Joseph Cook to discuss Carmen on this Backstage episode. Built at Amadeus and now part of the GSF ecosystem, Carmen helps organizations measure software carbon emissions at both infrastructure and application levels using existing observability and FinOps data, all powered by the GSF Impact Framework. They discuss why granular, team-level emissions data matters, how Carmen works in practice, and how standardized, transparent measurements can turn sustainability insights into concrete engineering action.

Anne Currie hosts Anna Forlati to discuss why sustainability is not a cost center but a business advantage. Drawing on her journey from UX designer to Head of Digital Sustainability and Impact, Anna explores how inclusive design, ESG strategy, and cultural change can make digital products more resilient, ethical, and profitable. From B Corps and EU regulation to GreenOps and AI efficiency, the conversation reframes sustainability as a mindset shift that aligns purpose, performance, and long term value.

In this episode, host Chris Adams is joined by Wilco Burggraaf and Robert Keus of GreenPT to unpack what greener prompting and transparent AI actually look like in practice. They discuss why most AI services hide their environmental impact, how GreenPT exposes real energy and carbon data to users, and why user behavior plays a major role in AI’s footprint. The conversation explores prompt length, session design, model efficiency, and the limits of chat-based AI, making a strong case for transparency, better defaults, and more purposeful use of AI if it’s going to scale responsibly.

Chris Adams speaks with Tom Kerkhove of the Microsoft Azure API Management team about how thoughtful API design can reduce energy use and improve system efficiency. They discuss how API gateways, caching, throttling, and observability can cut unnecessary compute and data transfer, while also improving reliability and developer experience. The conversation shows how small architectural decisions at the API layer can have an outsized impact on cost, performance, and sustainability at scale.

Anne Currie is joined by Sara Bergman to explore what the shift to greener computing really looks like in practice, using .NET and modern CPU architectures as a concrete example. They unpack why moving from traditional x64 systems to more efficient ARM-based platforms can cut costs and carbon, how runtime environments like .NET make architectural transitions easier, and why staying up to date with platforms is essential for performance, security, and sustainability. Along the way, the conversation connects DevOps, modernization, and energy efficiency into a clear message: the green shift starts with building systems that are designed to change.
