The Green Games in Tourism/ Hospitality project (http://goo.gl/RVKd0J) consisted of partners from Ireland, the UK, Germany, the Basque country and Austria. The central aim of the Green Games project was to develop an online digital game and game-based-learning-methodology, along with associated guidelines and training for learners, for the understanding and implementation of knowledge and skills related to food and water waste and energy management within the Tourism and Hospitality sector, in addition to advocating attitudinal change and endorsement of relevant environmental values. The project was also tasked with researching sustainability education in the tourism and hospitality sector and activities related to “green” education in the tourism and hospitality sector and for the acquisition and transfer of similar competencies through digital games.The project achieved this by creating a digital game for mobile devices (tablets and smartphones) to develop skills & competencies in the areas of food, water & energy waste. A number of prototypes were developed before the developed game was created, based in the genre of business resource-management/ strategy – similar to highly-popular and successful games such as “Hay Day” or “Middle Manager of Justice”. The developed game – “The Green Hipster Hotel” - is currently freely available on all major mobile formats and can be installed from the Apple iTunes store (https://goo.gl/7lIGVQ) and/ or Google Play store (https://goo.gl/2nwfrS). The game was also shortlisted for the best mobile game at the 2015 European Conference on Games Based Learning (http://goo.gl/nnwE07).In addition, a number of research results were developed in accordance with the project activities, dealing with existing tourism and hospitality VET environmental education competencies, as well as a number of reviews of existing digital entertainment and existing “serious” environmental-orientated games, as well as their potential applicability in the classroom. Additional supplementary educational material was also developed, including a wide range of educational animations based on the educational content of the game (https://goo.gl/bJo1C4), as well as an online learning platform to facilitate the use of the project game for teaching and learning (http://goo.gl/bkXEQH).
