2. Reducing Food Waste

2.1. Majorities of respondents in most countries and territories said they had tried to reduce food waste.

A majority of respondents (more than 50%) in 36 out of 37 surveyed countries and territories said they had tried to reduce their food waste in the prior month. Respondents in France (79%), Croatia (78%), and Italy (77%) were the most likely to say so, while respondents in the United States (60%), Japan (55%), and Israel (43%) were the least likely.

2.2. Most respondents who had tried to reduce food waste in the prior month said they faced no difficulties doing so.

Among respondents who said they had tried to reduce food waste in the prior month, majorities in nearly all countries and territories said they did not have any difficulties doing so. Respondents in Europe were most likely to say they had not had difficulties, with large majorities saying so in Czechia (87%), and in Spain, Austria, Norway, and Finland (all 84%). The only country where fewer than 50% of respondents said they did not face any difficulties in reducing their food waste was South Korea (47%).

However, other respondents who had adopted this behavior did report facing some difficulties. South Korea (21%), the United Arab Emirates (13%), and Japan (12%) had the largest percentages of respondents who said they thought the changes to their shopping routines would disrupt their lifestyle.Respondents were allowed to select more than one answer to this question, unless they selected “I didn’t have any difficulties.” South Korea (21%), Japan (11%), and Saudi Arabia (11%) had the largest percentages who said they thought it would take too much effort. Trinidad & Tobago (15%), the United Arab Emirates (12%), and Oman (9%) had the largest percentages who said that no one they knew was trying to reduce their food waste. Chile (13%) and Israel (10%) had the largest percentages who said that they did not know how to reduce their food waste. Finally, South Korea (12%), Israel (10%), and New Zealand (8%) had the largest percentages who said that it took a lot of time to reduce their food waste.​

These heat maps show the percentages of people in 37 countries and territories who have NOT reduced food waste and the reasons they had not done so. Among those who had not tried to reduce food waste, the most common barriers were not having thought about it, not knowing how, or not being interested.

2.3. Among those who had not tried to reduce food waste, the most common barriers were not having thought about it, not knowing how, or not being interested.
