Removing carbon dioxide from the atmosphere is essential to meeting international climate goals, scientists say. Without it, it’s all but impossible to reach net-zero greenhouse gas emissions in time to limit global warming to 1.5 or 2 degrees Celsius, the primary targets of the Paris climate agreement.
Yet carbon dioxide isn’t the only climate-warming gas that needs a sharp cutback in the atmosphere. Experts are turning their focus to methane as well.
On Tuesday and Wednesday, the National Academies of Sciences, Engineering and Medicine hosted a workshop dedicated to atmospheric methane removal, which is the process of removing methane emissions directly from the air.
The workshop included presentations by dozens of researchers and policy experts addressing questions about the science and effectiveness of methane removal, potential side effects and unintended consequences and the ways it should be governed and regulated.
