Although we witness a proliferation of collaborative consumption platforms, especially in times of Covid19 pandemic restriction, when so many services moved to online, Elder persons (> 60 years old) have some specific challenges in front of these opportunities: lack of knowledge and Digital Skills for using of CC Platforms, lack o awareness of these opportunities and the risks (online security) which prevent them to use CC Platforms; This where our project steps in, by providing an innovative training program with the main objective of increasing the competences (attitudes, skills, knowledge) of Elder Persons(>60 years old) about how to exploit Collaborative Consumption (CC) Through the execution of this Project, 7 partners from 5 countries have: • developed Co-Created Methodological Guide, with the direct participation of End Users, determining the key contents, methodologies and tools needed for creating and improving the critical competences of Elder Persons (> 60 years old) for improving their access and exploitation of Collaborative Consumption • developed Training Materials addressed to Elder Persons for increase their access and exploitation of Collaborative Consumption. The structure of the Training materials is organized as follows: 1. Introduction to Collaborative Consumption (CC) 2. Impact of CC in Sustainability. 3. Evaluating my competences and expectations in CC. Self-assessment. 4. CC in the field of Wellbeing. 5. CC in the field of Energy and Water Consumption. 6. CC to reduce Wastes (inc. Food) and promote Recycling/Reusing. 7. CC in the field of Mobility. 8. CC for Sharing essential goods. 9: COL-SUMERS LAB. • developed Experiential Training Activities : based in practical and experiential training involving Elder Persons, focused in the optimal and oriented exploitation of aforementioned Training Materials within real environments. • developed an e-Training Platform (I.O.4), for supporting the implementation of the Training Methodology, including Training Materials(I.O.2), Designed Experiential Training Activities(I.O.3), Workspace and link to applicable ICT Tools and Collaborative Consumption Platforms. The platform is available at: https://platform.col-sumers.eu • developed 4 COL-SUMERS UNITS in the Consumers Associations belonging to the Consortium in order to ensure the sustainable exploitation of the project after the project lifetime. (Romania, Spain, Slovenia, Bulgaria and Greece) • dissemination Actions addressed to the European collective related to Consumption. The e-Training Platform (I.O.4), Training Materials(I.O.2), Designed Experiential Training Activities(I.O.3) have been produced in English, translated and available also in Spanish, Romanian, Greek, Slovenian and Bulgarian. From the COL-SUMERS project benefited a number of persons during the project lifetime:- 126 persons involved in the Co-Created Methodological Guide • 178 Elder Consumers have been trained through their participation in the validation actions of full training methodology which included: Training Materials (IO2), Designed Experiential Training Activities (IO2) and e-Training Platform (IO4). • more than 7.000 Persons, including Elder Consumers and other stakeholders (Romania, Spain, Slovenia, Bulgaria and Greece) have been made aware of project results, through multiplier events (175 persons) and dissemination actions to be carried on through the project website (>3000 page visits), newsletters (>3.500), leaflets (>3.500) .
