The problem of massive emissions of carbon dioxide (CO2) from the burning of fossil fuels and their climatic impact has become major scientific and political issues. Electricity generation, transportation, industrial and residential are the main sectors identified to contribute to the emission of CO2 in Malaysia. In this study, a comprehensive modeling tool, long-range energy alternatives planning system (LEAP) was utilized to project CO2 emissions from year 2000 to year 2020 for each sector. It was projected that without any mitigation measures being taken up by the country, 285.73 million tonnes of CO2 will be released in 2020, which is a 68.86% increase compared to the amount of CO2 emitted in year 2000. Electricity generation, which gives 43.40% out of total of emissions, was discovered to be the largest emitting sector among all sectors. In addition, this study also reviews recommended mitigation analysis proposed by other researches as well as implementation of energy efficiency program in Malaysia. This projection and mitigation is a hope to provide an important basis to reduce future CO2 emissions and their associated impact in Malaysia. © 2010 American Institute of Chemical Engineers Environ Prog, 2010.

Food waste has formidable detrimental impacts on food security, the environment, and the economy, which makes it a global challenge that requires urgent attention. This study investigates the patterns and causes of food waste generation in the hospitality and food service sector, with the aim of identifying the most promising food waste prevention measures. It presents a comparative analysis of five case studies from the hospitality and food service (HaFS) sector in Malaysia and uses a mixed-methods approach. This paper provides new empirical evidence to highlight the significant opportunity and scope for food waste reduction in the HaFS sector. The findings suggest that the scale of the problem is even bigger than previously thought. Nearly a third of all food was wasted in the case studies presented, and almost half of it was avoidable. Preparation waste was the largest fraction, followed by buffet leftover and then customer plate waste. Food waste represented an economic loss equal to 23% of the value of the food purchased. Causes of food waste generation included the restaurants’ operating procedures and policies, and the social practices related to food consumption. Therefore, food waste prevention strategies should be twofold, tackling both the way the hospitality and food service sector outlets operate and organise themselves, and the customers’ social practices related to food consumption.
