The main idea is to implement selected measures to improve cooking facility operated in the AIT campus. Technology intervention by introducing high efficiency of improved cook stoves and other measures will help to save the energy consumption at the same time minimize the negative impacts. The issues of air pollution, energy consumption and climate are inter-linked and certain efforts can be done to achieve co-benefits. Co-control approach implemented in initiative is relevant to cope with sustainability in every aspect. The approach will show the community on how energy and environmental problems can be solved at the micro-scale to achieve impacts on the bigger scale. This initiative is expected to be a “role model” in AIT community and can inspire people to replicate similar activities in other places. It is also important to convey a key message to the community that “global” air pollution and climate change mitigation measures are nearby and can be done at the “local” scale.

Our goal

  • To conduct benchmarking of the existing cooking facilities of the food vendors inside the AIT campus, such as type of fuel, quantities, stove technology, and exhaust condition
  • To assess environmental impacts of the existing facilities
  • To identify workable measures to mitigate the associated negative impacts
  • To Implement selected measure set in a “pilot case study”, and therefore the impacts can be measured
  • To develop the standard protocol to raise the public awareness among of vendors and visitors.

Our progress

Conducted surveys in order to acquire data on LPG fuel usage and sale. Pre-test questionnaires were circulated to 25 food vendor operators in AIT. It was revealed that out of 25 vendors, only 14 vendors cook on-site without using electric cookstoves. The questionnaires were then refined and distributed again among of these 14 vendors. In depth interview to the vendor owners was conducted. A detailed survey on the fuel consumption was also conducted by measuring daily residual weight of LPG tanks and charcoal storage for one week at the main vendors such as AITCC, the Park, Vietnamese restaurant, SU Snack Bar and duck pond restaurants.

Further activities will be carried out such as:

  • Conduct emission inventory of major air pollutants (CO, NOx, SOx, VOC) and greenhouse gases (GHGs) from public cooking facilities in AIT based on the results of survey of stove technology and fuel consumption
  • Conduct measurements of air quality both indoor and outdoor of selected restaurants
  • Identify and screen/rank measures to improve the current situation
  • Implementation of a selected measure in a demonstration project assessment of the performance.
