                                                        providing the same type
of climate-related disclosure in your SEC filings as you provided

   2.                                                   Disclose the material
effects of transition risks related to climate change that may affect
                                                        your business,
financial condition, and results of operations, such as market trends that
                                                        may alter business
opportunities, credit risks, or technological changes.

4.       It appears you have identified climate-related projects in your
Sustainability Report.
         Please tell us about and quantify past and/or future capital
expenditures for climate-related
         projects for each of the periods for which financial statements are
presented in your Form
         10-K and those planned for future periods.
5.       To the extent material, discuss the indirect consequences of
climate-related regulation or
         business trends, such as the following:
             decreased demand for goods or services that produce significant
greenhouse gas
              emissions or are related to carbon-based energy sources;
             increased demand for goods that result in lower emissions than
competing products;
             increased competition to develop innovative new products that
result in lower
              emissions; and
             increased demand for generation and transmission of energy from
alternative energy
              sources.
         Also, disclosure on page 23 of your Form 10-K appears to address
reputational risks
         related to regulatory changes surrounding greenhouse gas emissions and
other climate
         change-related laws and regulations. Tell us how you considered
providing disclosure
         regarding reputational risks as an indirect consequence of
climate-related business trends.
6.       We note your disclosure on page 16 regarding the impacts of extreme
weather conditions
         and natural disasters, including those caused by climate change.
Please further discuss the
         physical effects of climate change on your operations and results,
such as weather-related
         damages to your property or operations, and weather-related impacts on
the cost or
         availability of insurance. Include quantitative information with your
response for each of
         the periods covered by your Form 10-K and explain whether increased
amounts are
         expected in future periods.
7.       Tell us about and quantify any compliance costs related to climate
change during the
         periods for which financial statements are presented in your Form 10-K
and explain
         whether increased amounts are expected in future periods.
8.     If material, provide disclosure about your purchase or sale of carbon
credits or offsets and

of operations.
