The White House did not use the term "air quality" in this context. Here are the two opening paragraphs:
We have a moral obligation to leave our children a planet thatÂ’s not irrevocably polluted or damaged. The
effects of climate change are already being felt across the Nation. In the past three decades, the percentage of
Americans with asthma has more than doubled, and climate change is putting those Americans at greater risk of
landing in the hospital. And extreme weather events are becoming more frequent across the country – from
more rain falling in downpours in many regions, to longer and hotter heat waves in others, to more severe
droughts and wildfires in some areas, notably the West and Southwest. Through common-sense measures to cut
carbon pollution we can protect the health of our Nation, while stimulating the economy and helping to prevent
the worst impacts of climate change.
CLIMATE CHANGE CAUSED BY CARBON POLLUTION IS IMPACTING OUR COMMUNITIES
Climate change, caused primarily by carbon pollution threatens the health and well-being of Americans in many
ways, from increasing the risk of asthma attacks and other respiratory illnesses to changing the spread of certain
vector-borne diseases. Some of these health impacts are already underway in the United States and climate
change will, absent other changes, amplify some of the existing health threats the Nation now faces. Certain
people and communities are especially vulnerable to the health effects of climate change, including children, the
elderly, those with chronic illnesses, the poor, and some communities of color. In the coming years,
communities are expected to experience the following impacts in regions across the United States.

I'm not going to argue on their behalf. This is a rather weak point. Still, they're expressing a concern about the American people and they're trying to sell a position that many of your conservatives oppose. More power to 'em.
