Greenwashing — deceptively promoting one's organization's policies as eco-friendly — isn't something only big oil does anymore. Some of America's airlines are jumping on the greenwashing bandwagon. But they're not fooling us.

The European Union has set standards to limit global warming pollution by airlines, requiring them to pay a tax if they exceed the limitations. But the United States, along with other countries and many airlines are opposing the law. Several of the opposing airlines have consistently touted their respective commitment to keeping the environment clean.

If these airlines were so committed to environmental conservation, they shouldn't be trying to block clean air standards every step of the way. The same goes for the United States. If airlines don't want to pay the fine, they should find better ways to limit their emissions.

Write to President Obama asking he support the EU's emission standards.
