  Human-computer interaction (HCI) studies the design and use of interfaces and
interactive systems. HCI has been adopted successfully in modern commercial
products. Recently, its use for promoting social good and pursuing
sustainability, known as sustainable HCI, has begun to receive wide attention.
Conventionally, scientists and decision-makers apply top-down approaches to
lead research activities that engage lay people in facilitating sustainability,
such as saving energy. We introduce an alternative framework, Community Citizen
Science (CCS), to closely connect research and social issues by empowering
communities to produce scientific knowledge, represent their needs, address
their concerns, and advocate for impact. CCS advances the current
science-oriented concept to a deeper level that aims to sustain community
engagement when researchers are no longer involved after the intervention of
interactive systems.
