"Opening the door to dirtier cars that guzzle more gas is exactly the wrong move for the American auto industry. It's like making a bet on beepers in an age of smart phones."

Whittling away at the standards will undermine the global competitiveness of the U.S. auto industry. As shareholders in its biggest companies – with more than $250 million worth invested in Ford and General Motors alone – we believe we have a duty to weigh in on this move, on behalf of our pension beneficiaries and the economy as a whole.

Opening the door to dirtier cars that guzzle more gas is exactly the wrong move for the American auto industry. It's like making a bet on beepers in an age of smart phones. No consumer is going to get excited about paying more for options that deliver less.

For consumers – everyday families, and businesses small and large – the fuel savings on more efficient cars and trucks adds up. And when people and businesses have more money in their bank accounts, they tend to spend it, boosting economic growth in our communities, creating jobs and strengthening our nation's economy.

Giving up on strong standards means slowing the pace of innovation and investment. And that would allow foreign automakers to pull ahead of America's auto industry at a time when auto markets are increasingly global, and governments around the world are adopting standards that place a premium on clean, efficient, advanced vehicles. Not only are other countries requiring cleaner vehicles, but China, India, France, the United Kingdom and other nations have announced plans to ban traditional internal combustion engines entirely.

In response, automakers are bringing more and more advanced-technology rides to market, from conventional vehicles that get great gas mileage to hybrids to plug-in electric vehicles that go farther on a charge than ever before.

A two-year government review of the national gas mileage and emissions standards through 2025, reinforced by independent analyses, confirmed that the goals are economically and technically feasible. And given that transportation is now the largest source of U.S. greenhouse gas emissions, cleaner and more efficient vehicles have a key role to play in curbing climate change and the myriad risks it poses to our economy, City and planet, as well as to the City's pension funds.

Rather than spending time, money and political capital fighting for a rollback, U.S. automakers need to get on with becoming the leading car and truck manufacturers on the planet. They need to double down on building quality vehicles that offer a great driving experience while using less fuel and emitting less pollution. Doing so will help ensure their continued competitiveness — and keep institutional investors comfortable enough to keep betting American.
