Food miles refer to the distance food travels from where it is grown to where it is
consumed
The carbon footprint of food includes
greenhouse gas
emissions from production, transportation, and consumption.
What are the food miles of locally sourced produce compared to globally sourced produce?
Low
The carbon footprint of locally sourced produce is
lower
Why does importing apples from New Zealand increase their carbon footprint compared to locally grown apples in the UK?
Extensive transportation
Growing food is a factor contributing to the
carbon footprint
of food.
Match the food type with its carbon footprint (kg CO2e per kg):
Beef ↔️ 13.6
Chicken ↔️ 4.5
Tomatoes ↔️ 1.1
Lettuce ↔️ 0.3
How many kilograms of greenhouse gases are emitted to produce 1 kg of beef?
13.6 kg
The transportation of food contributes to its carbon
footprint
Chicken has a lower carbon footprint
per kilogram
compared to beef.
Steps in the environmental impact of food miles:
1️⃣ Longer distances traveled
2️⃣ Increased fuel consumption
3️⃣ Greenhouse gas emissions
4️⃣ Higher carbon footprint
What type of emissions are released when fossil fuels are burned for food transportation?
Greenhouse gases
Globally sourced food has lower food miles and a lower carbon footprint compared to locally sourced food.
False
Locally grown tomatoes have a lower environmental impact compared to those imported from
abroad
Higher food miles lead to a higher carbon footprint due to increased
fossil fuel
use.
What is the relationship between food miles and carbon footprint for locally grown apples?
Low food miles, low carbon footprint
Steps in reducing food miles and carbon footprint:
1️⃣ Choose locally sourced foods
2️⃣ Reduce transportation needs
3️⃣ Lower greenhouse gas emissions
4️⃣ Support environmental sustainability
Why do imported mangoes have a higher carbon footprint than locally grown apples?
Longer transportation
The carbon footprint of food includes emissions from
transportation
, storage, and consumption.
The use of fertilizers in growing food contributes to its carbon
footprint
Match the factor contributing to the carbon footprint of food with its description:
Growing ↔️ Use of fertilizers and equipment
Transportation ↔️ Distance food travels
Storage ↔️ Energy for refrigeration
Processing ↔️ Energy for packaging
Which food type emits the most greenhouse gases per kilogram, according to the table in the study material?
Beef
What is the carbon footprint of food?
Total greenhouse gas emissions
One factor contributing to the carbon footprint of food is the use of fertilizer in
growing
What are food miles related to in terms of the carbon footprint of food?
Transportation
Producing 1 kg of beef emits approximately 13.6 kg of
greenhouse gases
.
Steps in the lifecycle of food that contribute to its carbon footprint.
1️⃣ Growing
2️⃣ Transportation
3️⃣ Storage
4️⃣ Processing
What is the environmental impact of food miles?
Increases carbon footprint
Higher food miles lead to increased consumption of fossil fuels and greater greenhouse gas
emissions
Match the food source with its food miles and carbon footprint:
Locally Grown Apples ↔️ Low food miles, low carbon footprint
Imported Mangoes ↔️ High food miles, high carbon footprint
What are the key factors influencing food miles and carbon footprint?
Transportation, refrigeration, processing
Purchasing food from nearby farms is known as local
sourcing
Why does seasonal eating reduce the carbon footprint of food?
Less energy for storage
Sustainable transport methods, such as
rail
, lower fuel usage and emissions.
