The Math
This climate+ package assumes a year of food delivery once everyday.

Driving
The average car uses about 404 grams of CO2 per mile. To translate from
miles to kilometres, we divide miles by 1.609, and simultaneously divide
grams by 1.609. This means the average car uses about 251 grams of CO2 per
kilometer.
(divide by1.609) 1: 404grams (divide by 1.609)
0.6214:251grams
In order to convert grams of CO2 into metric tons we use the conversion
factor 0.000001
251 grams CO2 X 0.000001 = 0.000251 MT CO2
Let’s assume that the average distance of the restaurant you are ordering
from is 5km, so 10km round trip. To get to the total amount of carbon per
trip we will multiply 0.000251 MT CO2 by 10km. This means there will be a
total of 0.00252 MT CO2 emitted per trip.
0.000251 x 10km = 0.00251 MT CO2
Let’s say someone orders food once per day over a year. We will multiply
0.00251 MT CO2 by 365 days. This would equal a total of 0.91615 MT over a
year.
0.00251MT x 365 days = 0.91615 MT CO2
Meals
- Chicken - 1.36kg CO2 per serving
- Rice - 0.3315kg CO2 per serving
- Potatoe - 0.0438kg CO2 per serving
- Wine - 0.3123kg CO2 per serving
We are going to assume your meal includes one serving of chicken, rice,
potatoes and one glass of one. In total one meal would emit 2.0776 kg CO2
1.36+ 0.3315 + 0.0438 + 0.3123 = 2.0476KG CO2 = 2.05kg CO2
In order change this number from kilograms CO2 to MT CO2 we must multiply
2.05kg by the conversion factor 0.001 and get 0.00205 MT CO2
2.05 x 0.001 = 0.00205 MT CO2
Assuming you are eating out everyday for one year, you would be eating 365
meals. In order to find the total CO2 emissions we will multiply 365 by
0.00205 MT CO2.
365 x 0.00205 MT = 0.74825 MT CO2
Total
0.91615 MT + 0.74825 MT = 1.6644 MT CO2
