The Greenhouse Gas Emissions of Various Dietary Practices and Intervention Possibilities to Reduce This Impact

Abstract

This chapter examines the link between dietary choices and greenhouse gas (GHG) emissions and possible interventions to reduce this impact. The connections between climate change, food systems and public health are explored. It is shown that there is variance in the impact of different food types on GHG emissions, with animal products having the greatest impact. The role of food system activities in the production of GHG emissions is also explored. Dietary choices and GHG emissions are examined using case studies from a variety of countries. Results show that reduced animal food production has increased potential to reduce GHG emissions compared to technological mitigation or increased productivity measures. Finally, a systems science approach is used to explore possible interventions aimed at reducing consumption of animal products.

Rethinking the Reasons of Greenhouse Gases Emission in Asean Countries: Finding Reasons in Urbanization, Industrialization and Population Growth

“…In accordance with Green et al (2017), across all ASEAN countries, the population is more than 622 million of individuals. ASEAN make up the largest economy.…”

Collective intelligence for fighting food waste: changing the way things are done with participatory design

“…Food waste is responsible for the loss of valuable resources, especially as the natural resources required to produce food, such as land, water and energy, are depleted or wasted alongside the food itself. Food waste also contributes to greenhouse gas emissions (Munesue et al , 2015), not only because of the pre-sales production processes (Pradhan, 2023) but also because decomposing food produces methane (Green et al , 2017). Moreover, food waste exacerbates food insecurity and hunger, as it reduces the amount of edible food available for human consumption (Kong et al , 2022).…”
