GDP = gross domestic product, POP = population.<br />

Source: ERIA, calculated from the Cambodia Energy Balance Table 2010–2015.<br />

TPES is measured as the energy intensity multiplied by GDP:<br />

TPES = TPES/GDP × GDP<br />

The intensity effect is estimated as:<br />

(TPES/GDP) × GDP<br />

The production effect is estimated as:<br />

(TPES/GDP) × GDP<br />

Thus, the impact of the effects to TPES can be estimated as:<br />

TPES =(TPES/GDP) × GDP + Intensity Effect<br />

(TPES/GDP) × GDP + Production Effect<br />

Crossover Term<br />

Crossover term is just a term for the difference between the impacts of both effects<br />

with the changes in TPES.<br />

3.5.2 Energy and CO2 emissions<br />

CO2 emissions from fuel combustion can be calculated using the reference<br />

and the sectoral approaches as suggested in the 2006 Intergovernmental Panel on<br />

Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories. The<br />

reference approach provides simple estimates for CO2 emissions from all fuel<br />

combustion and some fugitive emissions.<br />

The sectoral approach provides estimates of CO2 emissions from the main<br />
