University College London has an extraordinary project going that fits the aims of P3 closely.
UCL’s Extreme Citizen Science (ExCiteS) group is an interdisciplinary research team that aims to challenge how we do science. Existing Citizen Science practices use educated citizens to participate in scientific data collection but not in formulating research questions or in analysis of results. We believe that the greatest future impact of science are likely to be gained when almost everyone is empowered to participate in research and use scientific tools to address local issues and share the knowledge globally. Extreme Citizen Science is science by citizens, regardless of their level of literacy or education. We develop tools and methodologies to facilitate anyone to collect, visualise and analyse appropriate data to raise awareness, and subsequently develop strategies, to address problems they have identified.

and they have an open-ended call for PhD students:
We seek research proposals that align with and complement our aims and objectives. Applications should formulate a clear research idea that contributes or extends ExCiteS activities, and which is theoretically sophisticated and methodologically novel. Your proposal should explain what your contribution will be, what methods you will use, an estimation of costs needed beyond the studentship (travel, equipment etc), and a timeline of key activities.
If you or anyone you know is looking for a combination sustainability/public-outreach doctorate, especially if you are lucky enough to be an EU citizen, have a look. (Applications are invited from UK and EU citizenship holders. Non-EU citizens are welcome to apply as well but unfortunately we are unable to cover the difference in tuition fee costs for them.)
