Question

Obama will drive up miles-per gallon requirements

Obama’s revision of auto-emission and fuel-economy standards will require automakers to boost fuel economy to 35.5 miles per gallon by 2016, notching up 5% each year from 2012, to limit the amount of carbon dioxide cars can emit.

what are the two benefits of the new miles-per gallon requirements?

Answer 1

This is the way of limiting carbon emission.

It has benefits as below:

No.1) protecting health: It gives clear air to breath, which ultimately improves human health.

No.2) protecting weather: Increasing the percentage of carbon dioxide in the air is the main cause of global warming; change in climatic conditions and increasing unbearable humidity are the effects of such global warming. If this continues one day may come when there will be lives in this world. The new requirement is just an attempt to protect weather and to save earth.
