Happy Earth Day! Join GreenSigns in celebrating our favorite holiday. Since our inception, GreenSigns is committed to putting planet before profit. Our digital billboards run on 100% renewable energy. The structures that hold those billboards were constructed from recycled steel and recycled plastic resins. And we work to ensure our supply-chain partners share our green mindset. What steps is your business taking to better the planet?
