The increasing number of registrations and usage of private airplanes have an outside impact of aviation emissions. This paper describes a design intervention to reduce private aviation specifically, and business travel in general, by use of holographic video conferencing technologies that seek to address deficiencies in current videoconferencing technologies. With an open-source technology roadmap for an interoperable holoconferencing system in mind, a campaign object – the COPCube – was created that will be used to lobby policymakers at the upcoming COP28 conference in Dubai, UAE, to reduce private travel, by example and regulation, and to invest in development of alternative technologies such as described in the paper.
