2), nitrogen oxides (NOx), sulfur dioxide (SO2), and energy consumption in Papua New Guinea by employing AIM/Trend model. The AIM/Trend is a energy related Green House Gas (GHG) emission predictor driven by past time series data of annual population, GDP, yearly NOx emission, yearly SO2 emission, and annual energy consumptions. For both NO2 and SO2, past time series data from 1990 to 2003 shows emission level increase of 55% and 38% respectively. 1995 to 2005 CO2 emission shows a jump by a massive 72%. From 2003 to 2030 both NOx and SO2 are projected to increase by 33%. Although the emissions from 1990 to 2003 are below the global average, it is a cause of concern due to the nature of increase within a space of 15 years. The model also shows that Oil energy consumption by 2030 is predicted to increase four folds relative to the 1985 levels. The total primary energy supply is conservatively project to grow from 0.8Mtoe to 1.8Mtoe whilst demand from 1.4Mtoe in 2002 to 3.7 Mtoe. The increase in the supply reflects a corresponding increase in GHG emission by 3 times relative to the 2000 level. At the current trends, the AIM/trend model suggests air pollution in PNG 40 years time is controllable. However, in terms of sustainability development of resources, energy intensity indicates needed concerted effort. For greater developmental sustainability, clean energy technology in industrial energy usage is recommended.
