The Paris Agreement: hold temperature below 2 C
That can only be done if we can:
Conserve
energy
Increase renewables and reduce coal
Remove CO

from
burning fossil
fuel
Remove CO
2
from the atmosphere.Slide3
The global carbon budget: how much CO
2
can we add to the atmosphere before we reach 2°C?

Sources of Carbon Dioxide
More CO
2
is emitted from coal fired electric generation plants than from any other technology or sector, including all modes of surface transportation combined.Slide12
Coal fired electricity production decline in 2016 is the
largest annual decline in tons and percentage since 1949.

What’s Driving the Decline of Coal in the United States?
“
natural
gas boom,
the falling cost of wind and solar energy
, and environmental regulations
