On 26th July 2023, CAM held its first multiplier event in Budapest. The participants were really interested in the project and green topics in general, 20 citizens attended the event. The programme covered the Greenvolve project with a special focus on the already developed Handbook and on green city elements such as green walls, composting, recycling of clothes, heat islands, etc. Based on the participants’ feedbacks, our initiation has a high relevance and they were looking forward to new outputs.
