3. California’s Dual Emissions Challenge – 80% Reduction in NOx and GHG
Federal Clean Air Act (CAA) - requirements to meet ozone standards in Central and Southern California air basins will require a 75% to 90% reduction in combustion emissions over the next 20 years.
California Climate Change Initiatives - Assembly Bill 32 “Global Warming Solutions Act” (AB32) and Governor’s Executive Order 2050 – set goals of reducing greenhouse gas emission by over 80% by 2050. 3

4. Technology Advances Key to Meeting the Emissions Challenge
•
Continuing progress on increased efficiency for all end-uses addresses both NOx and GHG
•
Optimized combustion / oxidation and after- treatment systems will meet the NOx challenge
•
Carbon-neutral gaseous fuels (such as biogas and Power-to-Gas) and carbon capture will meet the GHG challenge
•
High-potential emerging applications: Transportation, Distributed Gen, Power-to-Gas 4
