ACR+ member LIPOR and its associated municipalities have launched a campaign called "4M is for Everyone" to promote the "4M" principle. In Portuguese, 4M stands for less waste, less carbon, more climate and more biodiversity. Waste prevention, composting and recycling, biodiversity, urban gardens and mobility are some of the key issues to be addressed, always from the perspective of how citizens, with their choices, can join the 4M movement, assuming this strategy as a way of life and thus reducing their impact on the planet.  The campaign is based, in a first phase, on digital media, with approaches to the strategy and the issue, as well as challenges on social networks and the sharing of an online quiz called "Scan 4M".
