Today, President Obama signed into law a bill that would send a signal that it is way past time for aviation to reduce its global warming pollution. At the same time the White House signalled its commitment to securing a global solution to reduce aviation’s carbon pollution. We echo the Obama administration in calling for an international solution, as that is the best way to address the growing problem of carbon pollution from international aviation. We are glad that the Administration is signaling its willingness to roll up its sleeves to get that done. While the new law changes nothing, it serves as a timely reminder that the international community must work together, and quickly, to address carbon pollution from aviation.
