The global problem of food waste keeps piling up

• And as much as 8% to 10% of global greenhouse gas emissions are associated with food that is produced but not consumed, according to the UN Environment Program.

By the numbers: 1.3 billion metric tons of food never makes it to consumers, either lost between the farm and the market or wasted once it gets there, according to a new report from the appliance maker Bosch.

• China produces the most food waste overall, at 179 million metric tons, followed by India at 128 million metric tons and the U.S. at 45 million metric tons.
• On a per capita basis, Greece has the highest levels of household food waste, at 141 kg per capita, while Malaysia tops the table for waste from food service and retail establishments.

The other side: Russians stand out as unusually thrifty, wasting just 33 kgs per capita at the household level, the lowest in the world.

• U.S. households waste nearly twice as much per capita.

The bottom line: The good news for a still hungry world is that we can potentially feed more people without increasing emissions by making more out of what we already have.
