This paper estimates the historic relationship between carbon emissions and
GDP using data across countries and across time. We combine this relations
hip with plausible projections for GDP and population growth to construct a
model that offers insights into the likely path of global emissions in the
next century. In addition, we experiment with a method for incorporating o
il prices into the model: Our analysis provides independent confirmation of
the business-as-usual forecasts generated by the Larger structural models.
