The PA should forge a consensus among air carriers to accelerate adoption of a framework that calculates the carbon footprint of international air travel, quantifies the cost to offset and qualifies candidates for investment.
Remarks to Port Authority of NY&NJ, 10.24.2019
Last month, I contrasted the Port Authority’s $30 billion investment in air travel with the region’s need for sustainable, effective mass transit. Today I propose ways for the Agency to redress that imbalance.
Impact of Air Travel on the Environment
Air travel is a powerful agent of climate change.
- A person on a return flight between New York and London flight generates more CO2 than citizens of some countries produce in a year.1
- The altitude at which emissions are dispersed doubles their impact.2
- Flying’s “supernatural” speed enables trips that otherwise not be taken.3 4
- Technical innovation will make only modest reductions in emissions.5
- Resources devoted to air travel are unavailable to grow sustainable modes.
The air travel industry faces significant headwinds. A survey of European travelers forecasts that “flight shame” will slow growth from 4.5% a year to 1.5%.6 This will delay new plane orders and plans for airport expansion.7
In the U.S. the demand for carbon offsets is projected to grow to $3.8 billion per year for leisure travel and $2.4 billion for business. Beneficiaries will include rail operators, governments and forest landowners.8
In 2018, the Regional Plan Association recommended that the region’s airports be “hardened” to withstand 3-6 foot sea level rise.9 RPA’s caution may be prudent, but it misses the point. The immediate threat to those facilities is political, not physical.
As sea level rises and the effects of climate change manifest, public demand for carbon-neutral transport will intensify. By the time sea level rise reaches 3 feet, the PA will face an insurrection. New capacity will go unused, and “sunk costs” will be wasted.
What the Agency Can Do
In light of the evolving climate, political as well as environmental, the Agency should revisit its growth projections for air travel with an eye towards scaling back mid-to-long term expansion plans. This will free up resources to reinvest in sustainable transport modes.
Second, the Agency should forge a consensus among carriers to accelerate adoption of the CORSIA framework to calculate the carbon footprint of international air travel, quantify the cost to offset and qualify suitable candidates for investment.10 11
Online services already provide a comparable, voluntary opportunity to travelers.12 MyFlight.com prices a New York-London roundtrip at $50 to $150, depending on class of seating.
The Agency should further work to extend CORSIA to domestic flights. JFK, Newark and Laguardia together serve 140 million customers per year.13 Even 2% compliance generates a hundred million dollars for reinvestment in projects within the Port District.14
Major carriers have already embraced the concept. Delta Airlines purchased carbon offsets for 300,000 customers on Earth Day.15 And United Airlines has partnered with the Environmental Defense Fund and Conservation International to accelerate CORSIA implementation.16 17
Clearly, they see the marketing opportunity. Certainly, the existential threat to their business models. So should the Agency.

2 “The high cruising altitudes of jetliners exacerbate their climate impact. The contrails can form clouds that trap thermal radiation, and at that height, other emissions, such as nitrogen oxides, also contribute to warming. As a result, the total warming caused by aviation is estimated to be at least double the amount caused by the CO2 emissions alone.” Flight Shame: The Climate Hazards of Air Travel”, New York Review of Books, 8/28/19, https://tinyurl.com/y3ke7ly3

In other words, flying from JFK to LAX not only emits far more greenhouse gases than, say, taking a bus; if we had to travel by ground, we would be far less likely to make the trip at all.”, Ibid

8 Guilt over the environmental toll of air travel is causing customers to look for ways to offset carbon emissions, and also to take alternate modes of transport when possible. Over the next five years the cost of carbon offsetting for leisure travel alone will reach $3.8 billion per year, with the potential for that number to be 10 times higher.
