Since four years ago, Ireland adopts a new strategy to reduce its deficit: charging households and businesses for the environmental damage. Thus, government imposed taxes on most of the fossil fuels used at home, offices, vehicles, and farms based of course on each fuel’s carbone dioxide emissions, which immediately has an impact on the price of oil, gas, kerosene, etc. By this way, residents are billed for anything which wasn’t recycled. Now, the Irish pay purchase taxes on new cars in proportion to the car’s emission. Environmentally and economically, we can see very good results: this decline is awarded to a recession, changes in the behaviors also have a great role. The country’s emissions dropped 6.7 percent in 2011. When the Irish people were faced with this new environment which includes taxes, they quickly shifted to green ecology for cars, recycling. “Automakers like Mercedes found ways to make powerful cars with an emissions rating as low as tinier Nissians. With less trash. And a fossil fuels became more costly, renewable energy sources became more competitive allowing Ireland’s wind power industry to thrive” (1). But not everyone agree because of the prices of basic like gazoline and heating oil which have increased about ten percent. At a gas-station a woman said “ you call it a carbon tax, but what good is being done with it to help the environment”(1). Reference: The New York Times, E. Rosenthal.
