Food systems air pollution
Poor air quality is considered one of the greatest environmental mortality risk factors. While progress has been made on air pollution from the industry, transportation, solid waste management and household sectors, air quality has been largely absent from the discussion of food systems, and of human and planetary health. The development of tools for estimating air pollution from food systems have not kept pace with other sectors.
The European Commission’s Emissions Database for Global Atmospheric Research (EDGAR) is now used to develop an inventory of NH3, NOx, N2O, SO2, CO, non-methane volatile organic compounds, and particulate matter emitted in the production (including land-use change), distribution, consumption and waste of food. Air pollution emissions from food systems have risen over the past 50 years, corresponding to more than half of total nitrogen emissions and more than a third of particulate matter globally. More than a fifth of deaths due to poor air quality are related to pollution from food systems.
