Countries participating in the Paris Climate Act of 2016 have collectively agreed to reduce carbon emissions in an effort to keep global temperature rise below 2 degrees Celsius. There are two methods of reaching this goal. One is to reduce carbon emissions by using smarter and more efficient ways of powering our society such as renewable energy and biofuel. The other is to suck carbon out of the atmosphere or existing industrial emissions sources and either sequester it (put it back into the ground) or use it to make cleaner fuels and other products.
Globally, transportation accounts for 20% of total Green House Gas emissions. This is simply the carbon produced by sourcing, transporting, and consuming the fuel we use to drive our cars, fly and get from A to B. Reducing transportation emissions to a neutral or slightly positive carbon output would go a long way in balancing the carbon budget.
We can’t just replace the billions of cars that exist in the world with electric or hydrogen powered vehicles, and although the popularity of FCV and battery-powered auto brands is growing, this change will take time.
