Que signifie climate+?
Comment peut-on faire mieux?
- •Baisser le thermostat de deux degrés;
- •Porter tes vêtements plus d’une fois avant de les laver;
- •Te déplacer en vélo, à pied ou en autobus;
- •Faire la transition vers les ampoules DEL et les électroménagers intelligents;
- •Acheter des fruits et des légumes locaux et saisonniers;
- •Remplacer la pellicule plastique par des emballages alimentaires à la cire d’abeille;

Le calcul
The Math
This climate+ package assumes people use 1.5 straws, 1 plastic cup, 0.4 plastic water bottles and 2 plastic wrappers everyday over 10 years.
| Straws | 0.000779 MT CO2 |
| Cups | 0.00625 MT CO2 |
| Plastic Water Bottles | 0.0129 MT CO2 |
| Plastic Wrapper | 0.146 MT CO2 |
| x 10 years | |
| Total | 1.66 MT CO2 |
Straws
Canada uses 57 million straws per day and there are 37.6 million people in Canada, if we divide the number of straws by the number of people we get 1.5staraws per day per person
57 million straws / 37.6 million people = 1.515 straws per day per person
Each straw emits 1.46 grams of carbon, if each person uses 1.5 straws per day over one year they would emit 799.35 grams of CO2
1.46 grams per straw x 1.5 straw per day x 365 days = 799.35 grams CO2 per years
To get from grams to metric tons we use the conversion factor 0.000001and get 0.000779 MT CO2
799.35 kg CO2 x 0.000001 = 0.000779 MT CO2
Cups
Each cup emits 17.12 grams of CO2 , assuming people use 1 plastic cup per day equals 6.249 grams CO2
17.12 grams of carbon x 365 days = 6,249 grams CO2 per year
To get from grams to metric tons we use the conversion factor 0.000001and get 0.00625MT CO2
6,249 grams CO2 x 0.000001 = 0.00625 MT CO2
Plastic Water Bottles
Each water bottle emits 82.8 grams of CO2 and each individual uses 156 plastic bottles per year. If we multiply grams ofCO2 per bottle by the amount of bottles per year we get 12,916.8 grams of CO2 per year.
82.8 grams CO2 x 156 bottles = 12,916.8 grams CO2
To get from grams to metric tons we use the conversion factor 0.000001and get 0.0129 MT CO2
12,916.8 grams CO2 x 0.000001 = 0.0129 MT CO2
Plastic Wrapper
Assuming people use about 2 plastic wrappers per day, over a year , and each wrapper emits 200grams of CO2, in a year 146,000 grams CO2
2 bagsx 200grams CO2x 365 days = 146,000 grams CO2
To get from grams to metric tons we use the conversion factor 0.000001and get 0.146 MT CO2
146,000 grams CO2 x 0.0000001 = 0.146 MT CO2
Total
0.146 MT + 0.0129 MT + 0.00625 MT + 0.000779 MT = 0.166 MT CO2
Over 10 years of single use plastic 1.66 MT of CO2 would be emitted.
0.166 MT CO2 x 10 years = 1.66 MT CO2
