Environmental Engineering, disaggregation exponential growth question: Suppose world carbon emissions are expressed as the following product: Carbon Emissions= (energy/person) x (carbon/energy) x (population) If per capita enegy demand increases at 1.5% per year, fossil fuel emissions of carbon per unit of energy increase at 1% per year, and the world population grows by 1.5% per year, a) How long would it take before we are emitting carbon at twice the current rate? b) At that point, by what fraction would per capita energy demand have increased? c) At that point, by what fraction would total energy demand have increased?

Question
Environmental Engineering, disaggregation exponential growth question:
Suppose world carbon emissions are expressed as the following product:
Carbon Emissions= (energy/person) x (carbon/energy) x (population)
If per capita enegy demand increases at 1.5% per year, fossil fuel emissions of carbon per unit of energy increase at 1% per year, and the world population grows by 1.5% per year,
a) How long would it take before we are emitting carbon at twice the current rate?
b) At that point, by what fraction would per capita energy demand have increased?
c) At that point, by what fraction would total energy demand have increased?
