Last week the president challenged America to lead the world on climate solutions. Many American corporations are already on board, investing in high efficiency cars and trucks. Creating more fuel-efficient vehicles can have a huge impact on oil use and our climate. Everybody wins with increased efficiency. Companies save money. U.S. carbon emissions drop. And automakers push the boundaries of technology as they compete to build the highest efficiency cars and trucks.
Innovation driven by cost saving and climate progress will not only position the U.S. as a leader, it will eventually get us beyond oil. But as the president also said in his climate speech, we will not get there overnight. America will continue to rely on fossil fuels for some time to come. True as this is, it is also true that all fuels are not created equal. Companies with fleets of cars and trucks have a critical role to play ensuring that as America raises efficiency and embraces renewable fuels, we also turn away from the dirtiest, most carbon-intensive sources of oil -- Canadian tar sands.
