Now that 192 nations have ratified the historic Paris Climate Agreement, many have beefed up their efforts to reduce carbon emissions. One measure is to promote the sale of only 100 percent electric cars or to ban fossil fuel cars on the roads.
In the past couple of years, the clean energy revolution has steadily been gaining ground. Aside from transitioning to cleaner, renewable energy sources, a number of countries are also bent on keeping their roads clean by banning combustion engine vehicles. With the transportation sector contributing roughly 15 percent of man-made carbon emissions worldwide, this is a noteworthy step.
