FOOD TECHNOLOGY

Detailed explanation-1: -Globally, if food waste could be represented as its own country, it would be the third largest greenhouse gas emitter, behind China and the United States. The resources needed to produce the food that becomes lost or wasted has a carbon footprint of about 3.3 billion tons of CO2.

Detailed explanation-2: -CO2 accounts for about 76 percent of total greenhouse gas emissions. Methane, primarily from agriculture, contributes 16 percent of greenhouse gas emissions and nitrous oxide, mostly from industry and agriculture, contributes 6 percent to global emissions.

Detailed explanation-3: -The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks.

Detailed explanation-4: -Top 15 Countries with the Highest CO2 Emissions per Capita (t)-EU JRC 2020. By this measure, the U.S. has the thirteenth-highest per capita emissions at 13.68 tons, while Russia is 20th (11.64), Japan is 26th (8.39), China is 28th (8.20), and India is 110th with a mere 1.74 tons per capita.
