Pennsylvania’s Looming Climate Cost Crisis

Pennsylvania's municipal governments are projected to spend at least $15.47 billion by 2040 to adapt to climate change, with stormwater drainage capacity representing the largest expense at $7.8 billion. The report highlights that these costs will disproportionately affect rural, high-poverty, and Environmental Justice areas, with some small municipalities facing annual per capita costs exceeding $1,000. The authors argue that major oil and gas companies should be held legally accountable for these costs rather than taxpayers.

• Pennsylvania municipal governments are estimated to need at least $15.47 billion by 2040 to protect against extreme heat, heavy precipitation, and rising sea levels, averaging nearly $1 billion annually.
• Increasing storm drainage capacity is the most significant expense, accounting for 50% of total projected costs at $7.8 billion by 2040.
• Other major adaptation costs by 2040 include road maintenance ($2.98 billion), tree planting to combat urban heat islands ($1.7 billion), school HVAC upgrades ($1.23 billion), landslide protection ($935 million), and coastal defenses ($547 million).
• Climate adaptation costs will disproportionately burden vulnerable populations; rural communities face an estimated $5,990 per capita by 2040, while high-poverty areas face $5,870 and high-disability areas face $5,420.
• In 25% of Pennsylvania counties, municipalities will need to increase annual budgets by 5% or more to address climate impacts, which is nearly three times the average annual municipal tax increase of 1.8% seen from 1993 to 2021.
• Philadelphia faces the highest total adaptation costs at $3.3 billion by 2040, with annual costs of $190 million that would exceed the budgets of 40 of the city's 48 departments.
• Pittsburgh is projected to face $520 million in adaptation costs by 2040, with $380 million specifically for stormwater drainage.
• Small municipalities may face extreme fiscal stress; for example, Kingsley Township in Forest County is projected to have the highest annual per capita climate costs at $3,700 due to landslide protection needs.
• Sea level rise is expected to increase by 2.1 feet by mid-century and 4.7 feet by the end of the century, with 75% of communities incurring these costs being high-racial minority areas.
