ISO/DIS 14070-1:2026

Quantification of GHG emission rates from urban environments, where a wide range of GHG emission sources and sinks are located, requires atmospheric measurements to assess the background concentrations of GHGs that represent the incoming air stream and the GHG concentrations in the outgoing stream; the difference represents the “enhancement” of GHG concentrations due to emission sources and sinks within the control volume representing the urban dome. This document represents the first in a series of standards that establish requirements for accurate measurement of GHG emissions in urban environments.
