Day 50: Download a car sharing app and register

If everyone started car sharing today we’d reduce the number of cars on the roads by about 1 billion! Imagine how much better the traffic jams would be!

Car sharing, when implemented effectively, has the potential to significantly reduce carbon emissions. Here are a few reasons why:

1. Reduced Number of Vehicles: Car sharing programs encourage multiple users to share the same vehicle, leading to a reduced overall number of vehicles on the road. If more people share cars, fewer cars need to be manufactured, leading to lower emissions from the manufacturing process.

2. Increased Vehicle Utilization: Car sharing can lead to higher utilization rates for vehicles. Private cars are typically used only a fraction of the day, whereas shared vehicles are often in use by different individuals or families throughout the day, leading to better resource utilization and reduced waste.

3. Transition to Electric and Fuel-Efficient Vehicles: Car sharing services can invest in electric vehicles (EVs) or other fuel-efficient vehicles, reducing emissions associated with traditional fossil fuel-powered cars. Additionally, car sharing companies may have the resources to invest in the latest green technologies, further reducing emissions.

4. Encouraging Alternative Transportation: Car sharing programs can complement public transportation systems, biking, and walking, encouraging people to use these alternatives instead of relying solely on private cars. This shift to greener transportation options directly reduces carbon emissions.

It’s challenging to provide a specific numerical value for the reduction in carbon emissions without detailed data on the number of participants, their travel patterns, and the types of vehicles used. However, various studies and real-world examples have shown significant reductions. For instance, a study by UC Berkeley found that each car in a car-sharing program resulted in removing 9 to 13 privately owned vehicles from the road, leading to reduced emissions.

In summary, widespread car sharing has the potential to make a substantial impact on reducing carbon emissions, but the exact amount would vary based on the factors mentioned above. The promotion of car sharing, combined with investments in sustainable and efficient transportation options, can contribute significantly to mitigating the effects of climate change.


Imagine if 1 million people completed 100 Days to Save the World.

We would change the world.

It's possible.

Imagine how the world could be.

It's up to us to change it. Not someone else.
