The main project aim is to develop the capabilities of participating organizations through gaining creative marketing knowledge for increasing the awareness especially of public authorities and business sector about the three pillars of sustainable development [SD]: economic, social and environmental benefits.Previous experiences from preceding activities realized from consortium members, primarily based on achieved outcomes in YiA and Erasmus+ projects encouraged us to develop the idea of CBY in order to cooperate and exchange the best marketing practices and promotion tools for creating policies and implementing imaginative campaigns for SD using social media.The project gathers 12 partners from 11 countries: Bulgaria; Croatia; Czech Republic; FYR of Macedonia; Ghana; Kyrgyzstan; Nepal; Poland; Romania; Slovakia and Slovenia.Focus will be on creating synergies between the next objectives:1.Capacity building and networking of consortium members: NGOs, education (community learning centres) and business sector from Africa, Asia and Europe;2.Rising knowledge for SD (Economic, Social and Environmental well-being for today and tomorrow);3.Creative contribution of 3 existing marketing sub-disciplines: Green; Social and Critical marketing paradigm;4.Using marketing 8Ps instruments through gaining traffic or attention by social media in order to build awareness and SD knowledge;5.Increasing pressure on the public authorities and business sector for the implementation of policies for SD;6.To balance different, and often competing, needs against an awareness of the SD limitations we face as a society, without compromising the ability of future generations to meet their own needs.Project activities will be set on several different methodologies based on non-formal approach:1.Kickoff meeting and monthly online meeting of the implementation team;2.Two Mobility of youth workers (54 participants);3.Organizing 12 Training Course for own members and representatives of other NGOs, Business community and/or Local authorities;4.Final event ‘YouMUST: Do it!
