Open17 Challenge on Climate Justice

The Open17 Challenge is an interactive online coaching programme supported by Crowd4SDG, a three-year Horizon 2020 Research and Innovation Action aiming at achieving the SDGs focusing on climate action. The Open17 Challenge is open to any individual from around the world and encourages public participation and citizen science through the use of open data and crowdsourcing.

Selection Criteria

  • Novelty – Presentations should be about your ideas or a specific challenge rather than general problems.
  • Relevance – Proposals must address the topic of climate justice and help build community resilience.
  • Feasibility – Ideas should be ambitious but realistic.
  • Crowdsourcing – Proposals should explain how to get more people involved in helping you achieve your idea by either collecting data or taking collective action.


Applicants for the Open17 Challenge can be rewarded for their participation in the challenge with weekly €100 prizes for the best pitches. Two teams will be selected by a jury and invited to present their project in Geneva to potential UN and NGO partner organizations and impact investors at the international “Geneva Trialogue” conference in March 2023.

More information on the contest and participation modalities are available here. Deadline of submission is on 30 September 2022, midnight CEST.

#MakeMercuryHistory Photo Contest

The #MakeMercuryHistory Photo Contest is organized by the Secretariat of the Minamata Convention on Mercury, a global treaty
administered by the United Nations Environment Programme (UNEP). The contest invites photographers worldwide to raise awareness of the ongoing global concern of toxic mercury.

Selection categories

The Photo Contest is organized into three categories. You can send one picture per category :

  • Mercury contamination show that this critical issue transcends borders and affects us all.
  • The people working to phase out mercury from policymakers to academia and working on the ground.
  • The environment demonstrate what a world without mercury pollution would look like.


There will be one winner for each of the three categories listed above and nine finalists. Attractive rewards and visibility will be offered to each winner, ranging from a printed copy of their photo to participation in a physical exhibition at the fifth meeting of the Conference of the Parties to the Minamata Convention on Mercury (COP-5) to be held in October-November 2023 in Geneva, Switzerland.

Results will be announced on April 22 in honor of Earth Day 2023. Participation modalities are available here. Deadline of submission is on 31 December 2022.
