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

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.

Global GHG Emissions

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 countries realized that emission reductions were inadequate strengthened the global response to climate change adopted the Kyoto Protocol United Nations Framework Convention on Climate Change (UNFCCC) limit global temperature increases cope with its impacts Global GHG Mitigation

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

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 Perfluorocarbons ,200 Sulfur hexafluoride22,800

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 ~$ billion

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

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

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

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 Water and energy are dependent on each other; the use of one requires the use of the other.
