Climate 411

Hurricanes are getting stronger, more dangerous and forming earlier. Here’s how we can prepare.

Last week, Tropical Storm Arthur skirted North Carolina’s coast before veering into the Atlantic. While damage was minimal, this marked the sixth straight year that a named storm developed in the Atlantic before the official start of hurricane season on June 1.

Experts are predicting this year to be a very active hurricane season, and even more concerning, researchers from NOAA and the University of Wisconsin at Madison just released a study that found climate change is causing more intense and dangerous hurricanes. Their research indicates that the likelihood of a tropical cyclone becoming a Category 3 or stronger storm has increased 8% per decade as a result of climate change.

This news comes on the heels of several record-breaking hurricane seasons. It is a reminder of the urgent need to curb emissions to limit the worst impacts of climate change, while also working to build resilience to the changes we know are coming.

CORSIA: Industry-sought rule change threatens aviation climate program

The coronavirus pandemic has created a global health and economic crisis that has affected families all over the world and nearly all industries, with aviation taking a particularly steep toll.

Airlines may feel under pressure to save money at any cost, but hastily rewriting the fundamental structure of the industry’s flagship market-based program to address airline carbon emissions would be penny-wise and future-foolish.

In a new analysis by Environmental Defense Fund, we look at the implications of a rule rewrite sought by the International Air Transport Association (IATA) to the Carbon Offsetting and Reduction Scheme for International Aviation, or CORSIA.

The Trump administration’s air toxics loophole would intensify environmental injustice

By Taylor Bacon / Published: May 11, 2020

(Some statistics in this post were corrected on June 24, 2021)

One of the most disturbing aspects of the new coronavirus crisis is that people already struggling with underlying respiratory conditions seem to be at greater risk. This means that vulnerable communities already bearing the brunt of the health harms from dangerous pollution may suffer even more.

Yet the Trump administration has spent the last few weeks racing to roll back policies that safeguard the air we breathe. These rollbacks often impact vulnerable communities the most as well.

One such roll back is the proposed air toxics loophole, which would allow thousands of large industrial facilities nationwide to evade pollution controls and emit more toxic air pollution. In a previous post, we presented analysis of EPA’s own data indicating that the loophole could lead to an increase in emissions of hazardous air pollutants like benzene and mercury by over 49 million pounds across 48 states. We’ve now done further analysis and found that the facilities likely to increase toxic air pollution under this loophole are disproportionately located in vulnerable communities – leading to increased exposure to these dangerous pollutants for heavily minority and low-income neighborhoods.

Power company commitments to cut carbon pollution are an important step for our climate and health. Here’s what we need next.

By Taylor Bacon / Published: May 5, 2020

Arizona’s largest utility, Arizona Public Service, has joined over a dozen other power companies across the U.S. that have committed to delivering 100% carbon-free electricity by 2050. These commitments, which add to momentum for ambitious climate action and would significantly reduce health-harming pollutants that contribute to soot and smog, are a key step in addressing one of our nation’s leading sources of climate pollution. They also highlight the types of action that will be required across all sectors of the U.S. economy to reach net-zero economy-wide carbon pollution by mid-century, a target guided by science and supported in recent bills introduced in the U.S. Senate and House of Representatives.

Not only do these commitments show strong federal policy is feasible, they underscore that the Trump administration’s efforts to dismantle limits on carbon pollution from existing power plants ignore the most effective strategies for reducing pollution from the power sector. In fact, nine of the nation’s leading power companies recently submitted a brief in court opposing the Trump administration’s rollback for this very reason.

At the same time, these commitments by themselves are not enough. Due to the cost-effective pollution reduction opportunities in the power sector and the urgent need to reduce climate pollution by electrifying other sectors, even more ambitious near-term targets from power companies will be needed to achieve net-zero emissions economy-wide by 2050. In addition, commitments alone from power companies must be followed up with concrete actions that will achieve real reductions in carbon pollution – and reduce other harmful pollutants associated with premature death and respiratory illnesses.

California’s experience with buyer liability shows how aviation can help ensure environmental integrity

The International Civil Aviation Organization is preparing to stand up its market-based emissions reduction program, the Carbon Offsetting and Reduction Scheme for International Aviation, or CORSIA. As it does so, ICAO must maintain CORSIA’s environmental integrity.

To that end, airlines should not be allowed to count, for CORSIA compliance, carbon credits that have been found to be invalid, e.g., fraudulently issued or otherwise not meeting CORSIA’s standards for credit quality. To ensure that all credits represent actual emission reductions, such substandard credits should be invalidated – even if the fraud isn’t exposed until after airlines have canceled the credits in CORSIA. The emissions for which the credits had been tendered have occurred, and still need to be covered by valid reductions in order to meet CORSIA’s promise of “carbon neutral growth.”

California offers one approach to how CORSIA can do this. In its market-based climate program, California has developed a way to cover the emissions from invalidated credits to uphold the integrity of its program and encourage emitters to invest only in high-integrity offsets. It’s known as “buyer liability,” which means that if the California Air Resources Board (CARB), the regulatory body, invalidates offset credits, then those who purchased the credits for compliance with California’s emissions limit must replace the invalidated credits. This ensures that emitters meet their full compliance obligations and that they are more diligent in selecting offsets.

Early on, California’s buyer liability approach caused some uncertainty among offset project developers. But seven years of experience demonstrates that buyer liability has worked in California’s carbon market. Here’s how we know:

California must defend rules to protect health, especially now

A public health emergency is precisely the wrong time to undermine measures meant to improve air quality, address environmental health disparities, or ensure the sustainability of our common resources. In fact, the COVID-19 public health crisis makes it more essential that California upholds its bedrock environmental and health rules, and ensures clean air and water for all.

A preliminary nationwide analysis by Harvard University shows COVID death rates are higher in counties that had higher levels of air pollution in advance of the pandemic. This underscores the vital importance of pollution protections for human health, both during and after the COVID-19 crisis.

Understanding the importance of having rules to protect California’s health, environment and natural resources, 37 California legislators, led by Assembly Member Eloise Gomez Reyes, have called on Governor Gavin Newsom to “resist efforts to roll back any current protections” and to focus on the health and environmental impacts in the state’s most vulnerable and disadvantaged communities. They know that weakening these safeguards will mean more cancer, more asthma attacks, more heart and lung problems, and more loss of life for Californians.

The following summarizes some key programs and protections that appear to be under threat, and where California should heed the call of these legislators to stand firm:
