Although lay participation has long been a feature of scientific research, the past decades have seen an explosion in the number of citizen science projects. Simultaneously, the number of low-cost network connected devices collectively known as Internet of Things devices has proliferated. The increased use of Internet of Things devices in citizen science exists has coincided with a reconsideration of the right to science under international law. Specifically, the Universal Declaration of Human Rights and the International Covenant on Economic Social and Cultural Rights both recognise a right to benefit and participate in the scientific process. Whilst it is unclear whether this right protects participation by citizen scientists, it provides a useful framework to help chart the ethical issues raised by citizen science. In this chapter, we first describe the origins and boundaries of the right to science, as well as its relevance to citizen science. We then use the findings of a scoping review to examine three main ethical and legal issues for using Internet of Things devices in citizen science.

This chapter considers the research, development, and implementation of solar geoengineering by nonstate actors and their governance by intellectual property policies. Although some observers are concerned that nonstate actors could deploy it, states will probably retain control over operational decision-making regarding large-scale outdoor tests and implementation. At the same time, commercial entities will play roles – most likely as contractors in public procurement – as providers and innovators of goods and services for solar geoengineering activities. A leading means through which states govern nonstate actors in innovative domains is policies for intellectual property, particularly patents. This chapter reviews the current landscape of patents related to solar geoengineering and the social challenges that such intellectual property could pose. It comments on others’ proposals for intellectual property policies specific to solar geoengineering and also recommends one. Importantly, the suggested "research commons," which is centered on a system of patent pledges, does not require state action and could arise bottom-up among researchers and other nonstate actors.
