The transactions table for a closed economy is:

Agriculture Manufacturing Final demand Agriculture 10 20 50 Manufacturing 20 50 80 Primary inputs 50 80 The agriculture industry purchased 10 units of energy, the manufacturing sector 40 units.

(a) Calculate the energy intensities for deliveries to final demand by the agriculture and manufacturing industries.

(b) If the use of 1 unit of energy releases 3.5 units of CO2, calculate total CO2 emissions and allocate them to deliveries to final demand by the agriculture and manufacturing industries.

(c) Calculate what total CO2 emissions would be for deliveries to final demand of 100 from agriculture and 240 from manufacturing.
