Metric Ton Exercise
Scenario: A company produces 500 metric tons of steel per year. They want to reduce their environmental impact by decreasing their steel production by 10%.
Task: Calculate the following:
- How many metric tons of steel will the company produce after the reduction?
- What percentage of the original production will they be reducing?
- How much carbon dioxide (in metric tons) will they be saving if their steel production generates 2 metric tons of carbon dioxide per metric ton of steel produced?
Exercice Correction
1. New Steel Production:
Reduction = 500 metric tons * 10% = 50 metric tons
New production = 500 metric tons - 50 metric tons = 450 metric tons
2. Percentage Reduction:
The company will be reducing its production by 10% (as stated in the initial scenario).
3. Carbon Dioxide Savings:
Original CO2 emissions = 500 metric tons * 2 metric tons/metric ton = 1000 metric tons
New CO2 emissions = 450 metric tons * 2 metric tons/metric ton = 900 metric tons
CO2 Savings = 1000 metric tons - 900 metric tons = 100 metric tons
