This Recommendation provides deployment guidelines for ubiquitous sensor network (USN) applications and services for mitigating climate change. The scope of this Recommendation includes: ?C an overview of climate change monitoring; ?C analysis of environmental impact by USN applications and services; and ?C the requirements for deployment of USN applications and services for mitigating climate change. Monitoring climate change covers monitoring the status of greenhouse gas (GHG) emissions@ as well as monitoring climate change by tracing temporal changes of GHG emissions.
