Influence of access to clean fuels and technology, food production index, consumer price index, and income on greenhouse gas emissions from food system: evidence from developed countries.

Abstract

Sustainable development objectives heavily promote the advancement of cleaner production technologies to reduce emissions and conserve the average world temperature. For the years 1990-2020, the USA, China, Japan, Russia, Germany, and Australia are studied by using the panel fully modified ordinary least square (FMOLS). The results show that clean fuels and technologies and a consumer price index are helpful to reduce greenhouse gas emissions from food system which reduce environmental degradation. Contrarily, increased income and food production contribute to environmental deterioration. There are bidirectional Dumitrescu-Hurlin causal relationships between access to clean fuels and technology and greenhouse gas emissions from food system; real income and greenhouse gas emissions from food system; income and access to clean fuels and technology; income and consumer price index; and income and food production index. This research also revealed a unidirectional causation between the consumer price index and greenhouse gas emissions from food system; food production index and greenhouse gas emissions from food system; access to clean fuels and technology and the consumer price index; and access to clean fuels and technology and the food production index. These findings provide policymakers with relevant content: to promote the goal of green growth, the government should implement consistent measures to subsidize the food industry. Incorporating carbon pricing into food system emissions models would serve to lower production of polluting foods, which would enhance air quality indicators. Finally, a consumer price index should be controlled by controlling prices of green technologies in environmental modeling to improve sustainable development globally and reduce environmental pollution.
