Reducing carbon (and other climate forcing gases) outputs by 30% by 2030 is practical, feasible, and actually very conservative in terms of achievable. The utility companies will deny this, and counterargue, because it would mean an initial cut in their profits. But areas like the Hampton Roads area, Richmond, and Northern Virginia (DC suburbs) are low-lying and already significantly affected by effective sea level rise.

We needed to act 40 years ago. Failing to act now is ludicrous. I'd personally say that we need to reduce our carbon emissions by 50% - 75% by 2030, but 30% should be a no-brainer.

30 by 30, minimum.
