       Response dated September 28, 2021

       General

   1.                                                   Your response to prior
comment 1 refers to current or pending climate-related laws and
                                                        regulations in the
jurisdictions where you operate. Explain in greater detail how you
                                                        determined whether
these laws and regulations are reasonably likely to have a material
                                                        effect on you. Also,
tell us how you considered providing disclosure regarding the
                                                        difficulties involved
in assessing the timing and effect of pending climate-related laws or
                                                        regulations.
   2.                                                   Your response to prior
comment 2 states that you have not experienced material indirect
                                                        consequences of
climate-related regulation or business trends and that you do not believe
                                                        any such trends are
reasonably likely to have a material impact on your business, results
                                                        of operations or
financial condition. Please describe the indirect consequences you
 Brian L. Roberts
Comcast Corporation

         considered in your analysis and explain how you concluded they were
not material.
3.       Your response to prior comment 3 states that severe weather events
have impacted your
         business and operations for many years and discusses some severe
weather mitigation
         efforts; however, it does not appear to discuss the significant
physical effects of climate
         change, such as effects on the severity of weather, on your operations
and results.
         Accordingly, please revise to discuss the physical effects of climate
change on your
         operations and results or explain in greater detail how you concluded
that such effects
         have been, and are expected to continue to be, immaterial to your
operations and results.
         In order to help us assess your response, please provide a
quantification of material
         weather-related damages to your property or operations, a discussion
of how weather-
         related impacts have affected or may affect your customers and
suppliers and a discussion
         of any weather-related impacts on the cost or availability of
insurance.
4.       We note from your response to prior comment 3 that capital
expenditures for your
         climate-related projects have not, to date, been a material component
of your capital
         expenditures. Please provide us with additional detail supporting this
statement, including
         quantitative information.
5.       Your response to prior comment 4 appears to focus on your transition
to carbon neutrality
         by 2035 and concludes that you do not anticipate costs connected to
this goal to be
         material to your results of operations or financial condition. Please
tell us more about
         how you considered providing disclosure quantifying the estimated
costs of achieving
         your carbon neutral goal and explain how you analyzed the materiality
of these costs.
         Lastly, please tell us about transition risks related to climate
change separate from those
         arising from your carbon neutral goal and explain how you considered
providing
         disclosure regarding their possible effects.
6.       Your response to prior comment 5 states that while annual compliance
costs related to
         climate change have increased, the increases have not been material to
the company.
         Please tell us about the nature of the compliance costs incurred,
quantify the increased
         amounts and explain how you analyzed the materiality of these
increases.
       Please contact Mitchell Austin, Staff Attorney, at (202) 551-3574 or
Anna Abramson,
Staff Attorney, at (202) 551-4969 with any questions.
