Do forest carbon credits work and actually help the environment?

Science

It takes a lot of fuel to get an airplane up in the sky and keep it there—which means a lot of emissions. In fact, the airline industry produces more greenhouse gases than many major countries. Most airlines know this isn't a good look, so they are pushing for cleaner fuels—and offering passengers the chance to help them offset a flight's carbon emissions. Book a trip with a big carrier and you might be asked if you want to invest in forest preservation, saving enough trees to soak up your jet-setting's environmental emissions.
