How did we calculate our estimates?
Pupils and their families delivering Cut Your Carbon actions resulted in an approx. emissions reduction of 629,155 kg CO₂E.
This is a total of savings across all 7 of the carbon emissions reducing actions. 2 of the actions do not result in direct emissions reductions.
The workings for each are explained below. Equivalencies were calculated here: https://www.epa.gov/energy/greenhouse-gas-equivalencies-calculator
Make at least one journey more sustainable. This resulted in an estimated. emissions reduction of 25,087 kg CO₂E.
We’ve opted to base this calculation on the average journey to school: 2.4 miles. A medium petrol car emits 0.28676 CO₂E p/m. This is 0.688224 CO₂E over
2.4miles. Our figure is based on a sum of 0.688224 kg CO₂E x 36,452 pupils switching a car journey for a walk/scoot/cycle.
Go meat-free for a day. This resulted in an estimated. emissions reduction of 115,379 kg CO₂E.
A vegetarian diet produces, on average, 3.4kg less kg CO₂E per day in comparison to one that contains meat. Our figure is based on a sum of 3.4 kg CO₂E x 33,935
pupils going meat free for a day..
Have a no food-waste weekends. This resulted in an approx. emissions reduction of 50,219 kg CO₂E.
The average person produces 143kg per year of food waste - this equates to approximately 784g over a 2 day period. An average of 1.96 kg CO₂E comes from
784gkg of food waste. Our figure is based on a sum of 1.96 kg CO₂E x 25,622 pupils having a no food-waste weekend.
Turn down the heating by 1° for a week. This resulted in an approx. emissions reduction of 74,464 kg CO₂E.
Turning heating down by 1°C for a week could reduce emissions by 310kg CO₂E. That’s 5.96 CO₂E per week. 2 child families remain the most common family size
and we can presume that many of these attend the same school and took part in the campaign. Our figure is based on a sum of 5.96 kg CO₂E x (24,988/2) pupils
turning down the heating by 1°C for a week.
Say ‘no’ to a new item. This resulted in an approx. emissions reduction of 172,060 kg CO₂E.
The most common category of purchase outside of essentials/services is clothing, and of this category the most popular item to purchase is a t-shirt. The lifetime
carbon footprint of a t-shirt is 7kg CO₂E. Our figure is based on a sum of 7kg CO₂E x 24,580 pupils saying no to a new item.
