Nowadays, climate change is a common concern of mankind. It represents an urgent and potentially irreversible threat to human societies and the planet. Additionally, World Health Organization
emphasized that the scale of environmental health problems has expanded from household (e.g. indoor air pollution), to neighborhood (e.g., domestic wastes) to community (e.g. urban air pollution) to region (e.g. transboundary contamination), and now to global level (e.g. climate change) (WHO, 2003). Therefore, the major challenge facing the world community is to achieve sufficient reduction in greenhouse gas emissions so as to avoid dangerous interference in the climate system. In the 2015 United Nations Climate Change Conference, the member of participants including Thailand agreed to reduce carbon output “as soon as possible” to keep global warming to well below 2 ℃ compared to pre-industrial level. In the 21st Conference of the Parties (COP21), also known as the 2015 Paris Climate Conference, Thailand commits to reducing greenhouse gases emission to 20e25% by 2030 (UNFCCC, 2016). In 2013, Thailand emitted 262.23 million tons of CO2 (European Commission, 2016). Therefore, many activities to produce products required in the country including agriculture, industry, and transportation sectors should be considered to help reduce carbon emission to the atmosphere.
