JPA or Joint Implementation Programme Activity

A Joint Implementation programme activity is a measure or a number of measures which result in a reduction of anthropogenic emissions that satisfy the criteria of additionality:

A JI programme activity is a single measure or a set of interrelated measures that result in a reduction of anthropogenic
emissions by sources or enhancement of anthropogenic removals by sinks that are additional to any that would otherwise occur.

Joint Implementation Programme Activities are classified by type according to the technologies and/or measures involved and the baseline setting and monitoring plan used:

A type of JPA is defined by the technologies and/or measures to be used and includes a selection and a justification of the baseline setting and monitoring plan chosen for each technology and/or measure.
