2 We have three choices: mitigation, adaptation and suffering. Were going to do some of each. The question is what the mix is going to be? Dr. John Holdren, Science Advisor to President Obama We have three choices: mitigation, adaptation and suffering. Were going to do some of each. The question is what the mix is going to be? Dr. John Holdren, Science Advisor to President Obama Real adaptation is substantially more expensive than mitigation Real adaptation is substantially more expensive than mitigation Real adaptation without substantial mitigation is just a cruel euphemism Real adaptation without substantial mitigation is just a cruel euphemism Real adaptation by itself is so expensive (and endless) that it is essentially impossible to imagine how a real adaptation bill could pass Congress Real adaptation by itself is so expensive (and endless) that it is essentially impossible to imagine how a real adaptation bill could pass Congress The goal should be to choose a mix that minimizes the sum of mitigation, adaptation and suffering costs Even with todays climate we need to invest in a more resilient coast Even with todays climate we need to invest in a more resilient coast 2

3 3 Coasts are already experiencing hazards related to climate and sea level rise (very high confidence) The Business Case As a company serving the Gulf Coast, Global Climate Change effects put at risk: As a company serving the Gulf Coast, Global Climate Change effects put at risk: Our customer base Our customer base Welfare of our employees, their families and our communities Welfare of our employees, their families and our communities Billions of dollars of investment Billions of dollars of investment Louisiana coast line loses 24 square miles a year.

4 4 Coasts will be exposed to increasing risks over coming decades due to many compounding climate change factors (very high confidence) Rise in sea level of 1.0 m by 2100 Rise in sea level of 1.0 m by 2100 Rise in sea surface temperature 3oC Rise in sea surface temperature 3oC Intensified storms Intensified storms Storm Surge (Cat 3 = 3-4m) Storm Surge (Cat 3 = 3-4m) Subsidence 1.0 m by 2100 Subsidence 1.0 m by 2100

13 13 What is at stake

14 14 What are the physical risks? Damage to power plants, T&D system & Operation Centers from more frequent, intense storms & flooding Damage to power plants, T&D system & Operation Centers from more frequent, intense storms & flooding The load: where will it be and how much The load: where will it be and how much Disruptions in supply chain from storm events Disruptions in supply chain from storm events Availability of insurance & cost Availability of insurance & cost Loss of customer base and employees from fear of future storm damage Loss of customer base and employees from fear of future storm damage Reduced economic well being of the area from investments needed to adapt to climate change Reduced economic well being of the area from investments needed to adapt to climate change

15 Going forward, the risk we face is just going to increase, given economic growth, subsidence and climate change 15 New Orleans Skyline 1 Represents cumulative of average expected losses between 2010 and Asset value (replacement cost) for New Orleans buildings are $60 bn SOURCE: Swiss Re; Moodys; FEMA; MMS; EIA; OGJ; Wood Mackenzie; Energy Velocity; team analysis; others To place this in context, ~$370B could be used to reconstruct New Orleans buildings six times over – 2030 Cumulative Losses Extremechange Averagechange Todays climate 345 Cumulative annual expected losses $ Billions; 2010 dollars

16 16 A set of resilience measures needs to be deployed, based on their cost / benefit characteristics Cost per unit of benefit$ Loss averted, 2030 Cost-benefit ratios calculated based on discounted present value estimates Actions below 1 $/$ line on the y axis provide net economic benefits (benefits refer to loss averted ) Reduction of the expected loss in 2030, by countering the effects of climate risk 1 0

17 A large range in cost-benefit assessments exists for the potential portfolio of measures 17 Note: Costs and benefits refer to net present values Build all new residential buildings with 110-mph rated shingles, applied with adhesive strips Build all new residential buildings with 110-mph rated shingles, applied with adhesive strips Improved roof cover, new builds C/B ratio: ~0.3 C/B ratio: ~0.3 Cost: $34M Cost: $34M Benefit: $990M Benefit: $990M Homes affected: 1.7M Homes affected: 1.7M Increase vegetation management cycle frequency and remove hazard trees Increase vegetation management cycle frequency and remove hazard trees Vegetation Vegetation management, distribution C/B ratio: ~1.0 C/B ratio: ~1.0 Cost: $470MM Cost: $470MM Benefit: $480MM Benefit: $480MM Miles affected: 51,000 Miles affected: 51,000 All existing residential homes in the most flood-risk counties are elevated 10 ft All existing residential homes in the most flood-risk counties are elevated 10 ft Home elevation, retrofits C/B ratio: ~5.5 C/B ratio: ~5.5 Cost: $6.3B Cost: $6.3B Benefit: $1.2B Benefit: $1.2B Homes affected: 123,000 Homes affected: 123,000

18 And there are some key near term actions to protect our region that are cost effective, and will help our economy and our environment 18 Residential/ commercial 1 Building codes Oil and gas 6 Floating production systems 7 Replacing semi-subs with drill ships 8 Levees for refineries, petrochemical plants Infra- structure/ Environ- mental 3 Wetlands restoration 1 2 Beach nourishment 4 Levee systems 1 Electric utility 9 Resilience of electric utility systems Loss averted, 2030 $ Billions 1 Included despite high C/B ratios due to strong co-benefits, risk aversion 2 Total capital investment, non-discounted, across 20 years 5 Improved standards offshore platforms Total C/B ratio x CapEx required 2 $ Billions Public funding Private funding

19 19 Implementing these key measures will require leadership and coordination across stakeholders Engagement that would need to occur 1.7 million new buildings affected 1.7 million new buildings affected 3.2 million buildings retrofitted 3.2 million buildings retrofitted Includes stronger roof covers and roof wall connections Includes stronger roof covers and roof wall connections ~230 miles of beach nourishment ~230 miles of beach nourishment ~1000 square miles of wetlands restored ~1000 square miles of wetlands restored ~120 miles of levees ~120 miles of levees 102 levees to protect refineries and petrochemical plants 102 levees to protect refineries and petrochemical plants 19 FPSOs deployed 19 FPSOs deployed 2.2 MM of boe in new offshore production capacity developed using higher specifications 2.2 MM of boe in new offshore production capacity developed using higher specifications ~540,000 miles of new, rebuild or retrofitted resilience distribution lines ~540,000 miles of new, rebuild or retrofitted resilience distribution lines ~1,600 miles of new, rebuild or retrofitted resilience transmission lines ~1,600 miles of new, rebuild or retrofitted resilience transmission lines Increasing vegetation management Increasing vegetation management 1 Total capital expenditure, non-discounted, across 20 years FOR DISCUSSION Residential/Commercial $12B in CapEx 1 Infrastructure/Envionmental $44B CapEx 1 Oil and gas $50B CapEx 1 Electric utility $15B CapEx 1
