    Climate change is a major environmental challenge that should be mitigated by all parties concerned. One such party is the KMITL Lifelong Learning Canter (KLLC) which has committed to reducing its environmental externalities, including the impact of its operations on climate change. The idea of a “green KLLC” seeks to reduce adverse effects on the environment and improve indoor environmental quality through the use of natural building materials and biodegradable products, resource conservation (water, energy, paper), responsible waste disposal, and eco-friendly practices (recycling). To reduce these environmental externalities, the environmental performance of the KLLC canter should first be examined to establish measures for improvement. However, accurate evaluations of the environmental impact of Lifelong Learning Centers (LLCs) are uncommon because of the lack of data and the immaturity of appraisal methodologies. With a case study of KLLC, the newest LLC in Thailand, this paper appraises the environmental effects, thus setting benchmarks for subsequent studies. The appraisal demonstrates that the KLLC community can significantly reduce the environmental consequences by using e-certificates, motion sensor light installation, banana leaf packaging, solar cell installation, and carpooling systems. Although e-certificates and banana leaf packaging are the most cost-effective methods of implementation, the adoption of carpooling systems and electric vehicles demonstrates the highest potential for Greenhouse Gas (GHG) emissions reduction. The paper showcases how KLLC can reduce its GHG emissions and wastes, thus turning into a more environmentally sustainable business.

    Energy efficiency and environmental impact analysis in grocery store market in Canada
    (2018-01-01)

    There is growing pressure to limit Global Warming Potential (GWP) as it is the most significant way to reduce serious threats to people. The increase of average temperature in the atmosphere causes adverse effects on the environment, and this is changing the way business operates. Together with undergoing changes to be more environmentally friendly, the majority of business sectors has been launching many projects to reduce environmental impacts. Similar to grocery sector in Canada, many companies have been reported to investigate the environmental performance. Loblaw Companies Limited, the largest food distributors in Canada, has put more concerns on environmental impacts and worked diligently to reduce greenhouse gas (GHG) emissions through actions such as improving energy efficiency reducing refrigerant leaks, and incorporating renewable energy sources. This study analyzed Loblaw's energy efficiency and environmental performance and provided suggestions in the applications of skylight improvement, geothermal, refrigeration systems, kinetic energy to electricity, and e-grocery shopping. The results showed that the environmental concerns were substantially decreased. However, types of lights and refrigerators, distance driven, vehicle types, fuel used in e-grocery shopping results in the different amount of emissions; consequently, the GHG emissions varied depending on these factors. By integrating more environmentally technology, Loblaw could further reduce their emissions and waste and become a more sustainable company.
