Characterizing uncertain sea-level rise projections to support investment decisions

Many institutions worldwide are considering how to include uncertainty about future changes in sea-levels and storm surges into their investment decisions regarding large capital infrastructures. Here we examine how to characterize deeply uncertain climate change projections to support such decisions using Robust Decision Making analysis. We address questions regarding how to confront the potential for future changes in low probability but large impact flooding events due to changes in sea-levels and storm surges. Such extreme events can affect investments in infrastructure but have proved difficult to consider in such decisions because of the deep uncertainty surrounding them. This study utilizes Robust Decision Making methods to address two questions applied to investment decisions at the Port of Los Angeles: (1) Under what future conditions would a Port of Los Angeles decision to harden its facilities against extreme flood scenarios at the next upgrade pass a cost-benefit test, and (2) Do sea-level rise projections and other information suggest such conditions are sufficiently likely to justify such an investment? We also compare and contrast the Robust Decision Making methods with a full probabilistic analysis. These two analysis frameworks result in similar investment recommendations for different idealized future sea- level projections, but provide different information to decision makers and envision different types of engagement with stakeholders. In particular, the full probabilistic analysis begins by aggregating the best scientific information into a single set of joint probability distributions, while the Robust Decision Making analysis identifies scenarios where a decision to invest in near-term response to extreme sea-level rise passes a cost-benefit test, and then assembles scientific information of differing levels of confidence to help decision makers judge whether or not these scenarios are sufficiently likely to justify making such investments. Results highlight the highly-localized and context dependent nature of applying Robust Decision Making methods to inform investment decisions.

Climate Action Plan Phase 1: Greenhouse Gas Emissions Reduction Plan

California Department of Water Resources (DWR) | May 18th, 2012

Summary

The California Department of Water Resources (DWR) in an effort to reduce its impact on the environment and lead by example, has developed this Greenhouse Gas (GHG) Emiss

The California Department of Water Resources (DWR) in an effort to reduce its impact on the environment and lead by example, has developed this Greenhouse Gas (GHG) Emissions Reduction Plan to guide its project development and decision making with respect to energy use and GHG emissions. It is now clearly understood that these gases enhance the Earth’s ability to absorb and retain the heat radiated from the sun. Increased concentrations of GHGs in the atmosphere are the principal cause of anthropogenic climate change. As the connection between GHG emissions and climate change has strengthened and California has established GHG policies and reduction goals, DWR has focused on its own GHG emissions and developed strategies to reduce its contribution to the global problem of climate change consistent with those policies and goals. This GHG Emissions Reduction Plan (Plan) is the first Phase in DWR’s Climate Action Plan and considers GHG emissions from all DWR activities. In this Plan, DWR details its progress and future plans for reducing GHG emissions consistent with the GHG emissions reduction targets established in Assembly Bill (AB) 32, Executive Order S-3-05, and DWR’s own policies, the aggressive steps it will take to reduce its emissions by over 80% below 1990 levels, and the steps that it will take to monitor its progress toward achieving these reductions. DWR estimates that its total GHG emissions in 1990 were nearly 3.5 million metric tons, roughly the equivalent of a coal fired power plant or 680,000 passenger cars. Most of these emissions were released as a result of generation of electricity used to move water through the State Water Project (SWP), which DWR owns and operates. Since 1990, DWR’s GHG emissions have fluctuated due to hydrologic conditions, water demands, and energy resources. DWR GHG emissions peaked in 2003 at over 4.1 million metric tons per year. This Plan shows how DWR will make substantial reductions in its GHG emissions in the near-term (present to 2020) and how it will continue to reduce emissions beyond 2020 to achieve its long-term (2050) GHG emissions reduction goals.
