Please advise us what consideration you gave to providing the same type of climate-related disclosure in your SEC filings as you provided in your Corporate Sustainability Report. Risk Factors, page 27 2. It appears that you have identified technological advances in fuel economy and energy generation devices, growing alternative energy sources, and the transition to a lower- carbon economy as transition risks related to climate change.

Tell us how you considered providing more detailed disclosure regarding past and future capital expenditures for these types of projects. Include quantitative information for each of the periods covered by your Form 10-K and for future periods as part of your response. 5. To the extent material, discuss the indirect consequences of climate-related regulation or business trends, such as the following; increased competition to develop innovative new products that result in lower emissions; any anticipated reputational risks resulting from operations or products that produce material greenhouse gas emissions; and developments that create new opportunities such as the use of lower-emission sources of energy and increased revenues through gas captured rather than flared. 6. We note that extreme weather conditions can interfere with your production and increase your costs and that damages resulting from extreme weather may not be fully insured. Disclose in greater detail the physical effects of climate change on your operations and results, including as it relates to the potential for indirect weather-related impacts that have affected or may affect your major customers or suppliers. In your response, tell us about and quantify weather-related damages to your property or operations and any weather-related impacts on the cost or availability of insurance for each of the last three fiscal years and explain whether changes are expected in future periods. 7.
