Call open from 1 August to 30 September 2022


The 2022 Open17 Challenge is managed by the Crowd4SDG project, a three-year EU project aiming to promote citizen science projects tackling the SDGs and focusing on climate action, and is in partnership with UNICEF’s Yoma initiative for “learning to earning”, and Goodwall, the social network connecting youth and opportunities.

How it Works

The Open17 Challenge is an online interactive coaching programme to help young global innovators connect and shape good ideas into viable social innovations projects, with a focus on the use of crowdsourcing tools and methodologies. The Open17 Challenge supports projects that leverage grassroots innovation and citizen science methodologies to tackle the 17 Sustainable Development Goals (SDGs), using open data and crowdsourcing technologies.


An Open17 coaching cycle starts with a call for projects to solve concrete challenges inspired by experts from UN agencies, International Organizations and NGOs targeting one or more of the SDGs. Open17 favors solutions that use crowdsourcing and open data.


The call is open to anyone, anywhere, over the age of 16. Applicants submit ideas for projects that tackle the challenge. The most promising applicants and ideas are selected and connected with like-minded innovators into global teams.


The teams receive interactive online mentoring and coaching from international experts and coaches over five weekly 2-hour sessions, to transform their ideas into viable projects. The most promising projects receive further support for their development.
