Traditional intercoms are a forgotten carbon sink, with a single 50-unit building generating up to 26 metric tons of CO₂ in operational emissions over a decade. G.Talk confronts this by dematerializing the intercom. It replaces kilograms of hardware with a single 6-gram smart tag, eradicating both the embodied carbon of the physical device and the operational carbon from parasitic energy drain. Guided by the belief that sustainability must serve planet and people equally, this revolution transforms a carbon liability into a human asset—a design that is "Born Green" and "Born Equal." This promise is delivered through default-on accessibility: AI-powered summaries act as a digital memory for users with memory challenges, while a simple one-tap NFC interaction ensures users of all digital literacy levels are included. This isn't an iteration of the intercom. It is a fundamental redefinition of how buildings and people connect.
