|a Today the Administrator is proposing to find that
greenhouse gases in the atmosphere endanger the public
health and welfare of current and future generations.
Concentrations of greenhouse gases are at unprecedented
levels compared to the recent and distant past. These high
atmospheric levels are the unambiguous result of human
emissions, and are very likely the cause of the observed
increase in average temperatures and other climatic
changes. The effects of climate change observed to date
and projected to occur in the future – including but not
limited to the increased likelihood of more frequent and
intense heat waves, more wildfires, degraded air quality,
more heavy downpours and flooding, increased drought,
greater sea level rise, more intense storms, harm to water
resources, harm to agriculture, and harm to wildlife and
ecosystems – are effects on public health and welfare
within the meaning of the Clean Air Act. In light of the
likelihood that greenhouse gases cause these effects, and
the magnitude of the effects that are occurring and are very likely to occur in the future, the Administrator
proposes to find that atmospheric concentrations of
greenhouse gases endanger public health and welfare within
the meaning of Section 202(a) of the Clean Air Act. She
proposes to make this finding specifically with respect to
six greenhouse gases that together constitute the root of
the climate change problem: carbon dioxide, methane,
nitrous oxide, hydrofluorocarbons, perfluorocarbons, and
sulfur hexafluoride.
The Administrator is also proposing to find that the
combined emissions of carbon dioxide, methane, nitrous
oxide, and hydrofluorocarbons from new motor vehicles and
new motor vehicle engines are contributing to this mix of
greenhouse gases in the atmosphere. Thus, she proposes to
find that the emissions of these substances from new motor
vehicles and new motor vehicle engines are contributing to
air pollution which is endangering public health and
welfare under section 202(a) of the Clean Air Act. |
