Carbon dioxide, a major greenhouse gas has become an indicator in global warming and climate change. Meanwhile, cities are a medium whereby the source of carbon dioxide is released due to the urbanization and transportation sector. This situation leads to unpredictable impact to the environmental, social and economic condition of the city. Kuala Lumpur is a capital city that experiences rapid growth and was chosen for input-output analysis while Bukit Bintang road and Tunku Abdul Rahman road were chosen for ambient air monitoring due to traffic congestion problems in the city centre. The ambient air quality monitoring was measured on Saturday, Sunday and Monday for 8 hours. The sampling started at 7.00 a.m until 3.00 p.m. with a 5-minute log interval. The study found that carbon dioxide emission from both roads in Kuala Lumpur contributed to 376 ppm of carbon dioxide showing that transportation was a massive source of greenhouse gas emission in the city. Meanwhile, the input-output analysis in Kuala Lumpur showed a significant increase between 2010 and 2016 where electricity consumption, food consumption input, water consumption, gas emission and wastewater output rise due to urbanization and increasing population in the city. In contrast, the enforcement of mandatory waste management by the government has resulted in the decrease of solid waste output in Kuala Lumpur. The greenhouse gas released output in terms of Global Warming Potential from the input-output analysis was 5.88 MMtCO2eq. The study showed that the impact of urbanisation such as ambient air pollution is closely related to energy consumption and greenhouse gas emission.

Electricity is an essential element for the production and the consumption in any economy. Electricity can be generated by thermoelectricity, hydroelectricity, nuclear power, solar power and wind power, etc.Each method of electricity production can make the level of greenhouse gas emissions of the economy differently. This study adopted Input - Output analysis method to examine the electricity requirments and greenhouse gas emissions in the Vietnamese economy.

Purpose – The purpose of this paper is to be limited to provide an overall economic structure linked with a particular hospitality industry by identifying the economic structure of relations between the two hotel industries and other industries within a particular state in the USA. Design/methodology/approach – The analyses of output, labor income and employment multipliers from the input–output system were performed using the IMPLAN 3.0 software. The study attempted to compare the hotel/motel industry (industry code 411) and the accommodations industry (industry code 412) with the top ten industries and averages of each set of multipliers to estimate the relative importance and contribution of the two hotel industries to the economy of Texas. After this comparison, the aggregated input–output tables and multipliers were prepared to determine the economic inter-relationship between the two combined hotel industries (industry code 411 plus industry code 412) and the non-hotel industries, using the criteria of the NAICS (North American Industry Classification System). Findings – The three findings of this study are summarized as follows. First, the two hotel industries impacted the state economy due to a high induced effect from output and a considerable direct, indirect and induced effect from labor income and employment, despite their relatively lower multipliers and the economic downturn in the state. Second, the hotel-related industry had a strong inter-dependent relationship with the finance and insurance-related industries. Finally, while the hotel industry generated more labor income and employment than did the other accommodations industry, it is interesting that the other accommodations industry created more output than did the hotel industry. Research limitations/implications – Other than limitations pertaining to assumptions of input-output model, an input-output analysis alone cannot become the best analytical method for decision-making. The study was a cross-sectional study with 2009 data and did not incorporate a time-series flow of the state economic structure over several decades. A study of the inter-relationship among varied states bordering the state could be worthwhile to identify the flow of inputs and outputs. Originality/value – Despite a considerable number of research in measuring the economic impacts, this paper was of great significance, in that the economic impact of the hotel industry that has never been performed in a particular state of the USA was analyzed. Additionally, these quantified economic data and results should be helpful to future plans and policies associated with the hotel industry.
