The Kyoto Protocol has recently opened new opportunities for joint imp
lementation (JI) activities between parties to the Framework Conventio
n on Climate Change. Before JI markets can develop, however stakeholde
r acceptability of the instrument must be enhanced. Remaining barriers
to acceptability include the lack of an agreed approach to assess add
itionality-the emission reductions achieved by a JI project relative t
o a baseline-and the lack: of an operational framework to ensure that
sustainable development and international equity objectives are met by
JI activity. Difficulties besetting current approaches to assessing a
dditionality are rooted in the uncertainties characterizing assumed ba
selines. This paper outlines an observable baseline framework for JI p
rojects in the energy sector, which could remove these uncertainties.
In contrast to current approaches to define baselines, observable base
lines are calculated from om a country's existing energy and emissions
data, and not from the particularities of a hypothetical baseline pro
ject. The framework provides for unique baseline definitions, permitti
ng unambiguous assessments of additionality. Furthermore, observable b
aselines dynamically adjust over time to ensure that many sustainabili
ty development objectives are met by JI activity. I will demonstrate a
number of sustainability benefits that naturally result from applicat
ion of the framework, and explore additional conditions that can be ad
ded to the framework to promote international equity objectives.
