This report outlines approaches to quantify the uncertainty associated
with national greenhouse-gas emission scenario projections. It does so by
describing practical applications of those approaches in two countries –
Mexico and South Africa.
The goal of the report is to promote uncertainty quantification, because
quantifying uncertainty has the potential to foster more robust climate-change
mitigation plans. To this end the report also summarises the rationale for
quantifying uncertainty in greenhouse-gas emission scenario projections.
