Barely a day goes by without a company talking up their green credentials -- how they're aligning themselves with global climate goals, cutting waste and upping their recycling. With all this corporate happy-talk about saving the planet on the rise, so are concerns about greenwashing. Investors and regulators are increasingly sounding the alarm about companies that exaggerate or misrepresent their environmental bona fides. That's what prompted academics at University College Dublin to develop algorithms to help the financial services sector detect and quantify greenwashing. Greenwashing encompasses everything from slightly disingenuous claims of being environmentally friendly to outright falsehoods.
