Hitting the targets could require a rapid shift to electric vehicles, the expansion of forests nationwide, development of complex new carbon-capture technology and many other changes, researchers said.
The Environmental Defense Fund has a clear message for the Biden Administration on the eve of an international climate summit marking the U.S.'s further re-entry into the Paris climate agreement: "We need to cut methane now."
The government estimates methane emissions in the oil and gas sector by mostly relying on mathematical modelling based on a small number of field measurements. But researchers say the government is underestimating those emissions, and better measurement techniques are possible.
"Time is running out to implement the Paris Agreement's emission targets to reduce global warming. The Arctic countries must take the lead in the run-up to COP26," said a spokesperson for Arctic Parliamentary Cooperation.
