means Making a product, company, or policy look environmentally responsible through marketing and branding while doing little or nothing to actually reduce environmental harm.

from A blend of 'green' (environmentally friendly) and 'whitewash' (to cover up faults or wrongdoing with a superficial, deceptive gloss). The term was coined in the 1980s, usually credited to environmentalist Jay Westerveld, who used it after noticing hotels urging guests to reuse towels 'to save the planet' — a cost-cutting move dressed up as eco-virtue. The word caught on precisely because the pattern was everywhere: the cover-up implied by 'whitewash' simply got painted green.
