1. Climate Change Climate Literacy 101 Session: Mitigation Jennifer Morales December 8 th, 2015

2. Mitigation Climate Change Mitigation refers to efforts to reduce or prevent emission of greenhouse gases. Mitigation can mean using new technologies and renewable energies, making older equipment more energy efficient, or changing management practices or consumer behavior. Climate Change Mitigation – UNEP www.unep.org/climatechange/mitigation

6. Global GHG Emissions

7. Continued negotiations among the 192 signatories amended the Protocol to achieve more ambitious results by 2030 The Kyoto Protocol legally binds developed countries to emission reduction targets 1995- countries realized that emission reductions were inadequate strengthened the global response to climate change 1997- adopted the Kyoto Protocol 1992- United Nations Framework Convention on Climate Change (UNFCCC) limit global temperature increases cope with its impacts Global GHG Mitigation

8. U.S. – China Climate Change Agreement (2014) U.S. to reduce GHG’s by ~ 27% below 2005 levels by 2025 China reach peak GHG’s in 2030 & increase renewable energy to 20% EU pledged to reduce GHG’s by 40% below 1990 levels by 2030 The Three Most Polluting Nations

15. California’s 2013 GHG Emissions Transportation= 37% Electricity Generation= 20% Industrial = 23% Agriculture = 8% Total California emissions in 2013 was 459.3 MMTCO ₂ e Other = 13%

16. What is CO₂e? There are many greenhouse gases of varying potencies; meaning some have more global warming potential than others. Some example greenhouse gases and their GWP (Global Warming Potential) in CO₂e CO₂e stands for Carbon Dioxide Equivalent GasGlobal Warming Potential (CO₂e -100 year) Carbon Dioxide1 Methane28 Nitrous Oxide298 Hydrofluorocarbons12-14,800 Perfluorocarbons7390-12,200 Sulfur hexafluoride22,800

18. 2005 EO S-3-05 Set the first GHG goals for State Agencies 2006 AB 32 Authorized a multi- year program to achieve long-range GHG reductions 2007 SB 97 Added GHG analysis requirement to the CEQA process 2013 Cap and Trade Created a carbon market with caps and reduction demands 2015 EO B-30-15 State agency GHG emissions 40% below 1990 levels by 2030 California Mitigation Legislation

19. Cap-and-Trade Goal is to reduce GHG by putting a cap on emissions that declines 3% every year. Emitters have to purchase additional emission allowances through an auction. The auction proceeds are used to fund GHG reduction programs. -Covers 85% of GHG emissions -All allowances for the current year, and some for future years are being sold -Should provide ~$2.2-2.5 billion

40. State Water Project Pumping SWP is a large power consumer in California 6-9.6 million MWh consumed per year 40-60% from our own hydropower

41. SWP Generation SWP is one of the largest generators of clean hydropower in CA 4 -7 million MWh generated annually Produces about 14% of California’s hydropower

42. Benefits to the Grid SWP’s off-peak pumping means fewer plants are cycling up and down, reducing the stress on the grid SWP’s off-peak pumping means fewer plants are cycling up and down, reducing the stress on the grid Limitations: Limitations: - Delta restrictions - Water deliveries drive power schedules

43. Take Home Messages Mitigation- reducing GHG emissions that contribute to climate change Mitigation planning is occurring at all levels of government, but statewide and global emissions are still rising as a whole. DWR is currently reducing its emissions and has ambitious plans to continue reducing through the year 2050. Water and energy are dependent on each other; the use of one requires the use of the other.
