Therefore, the researchers conclude, the total impact of obesity may be an extra emissions of ~700 megatons per year of CO 2 eq—about 1.6% of worldwide GHG emissions. Inasmuch as obesity is an important contributor to global GHG burden, strategies to reduce its prevalence should prioritize efforts to reduce GHG emissions.
