Climate change could potentially disrupt our ability to provide consistent mail service. To better manage emerging risks and ensure effective operations and resiliency, the Postal Service works to incorporate climate into strategies, plans, business processes and programs. In 2015, the Postmaster General reaffirmed this commitment in a memorandum. Internal steering and working groups track and manage climate change considerations in appropriate actions and policies. They also work to identify ways that long-term planning and collaboration can reduce or avoid costs associated with natural disasters, rising sea levels and temperature extremes. The groups take into account rebuilding costs, downtime, equipment loss, employee safety and other significant cascading effects resulting from climate change.
