AB 32 Scoping Plan
Our primary focus in 2008 has been working within Sierra Club California for the best-possible Scoping Plan under AB 32, where we developed and submitted detailed comments and spoke for the Sierra Club at public hearings.
AB 32 is California's landmark 2006 law to reduce global warming emissions to 1990 levels by 2020, about 30% from business-as-usual projected for 2020, 15% from todays levels, with a long-range goal of 80% from 1990 levels by 2050 (chart below; click to enlarge).
The largest two sectors of greenhouse gas emissions (below) are transportation
38% and electricity generation 23%.
This timeline below shows CARB's first milestones in 2007; developing
the high-level Scoping Plan over the last year; and the upcoming detailed
rulemaking through 2011 to implement it.
Following is the overview of how the Scoping Plan expects to reduce emissions.
Recommended Reduction Measures Counted Towards 2020 Target (MMTCO2E*)
ESTIMATED REDUCTIONS FROM CAP AND TRADE PROGRAM AND COMPLEMENTARY MEASURES 146.7
California Light-Duty Vehicle Greenhouse Gas Standards 31.7
ESTIMATED REDUCTIONS FROM UNCAPPED SOURCES 27.3
High Global Warming Potential Gas Measures 20.2
TOTAL REDUCTIONS COUNTED TOWARDS 2020 TARGET 174
