Social entrepreneurship creates green industry, which helps to solve environmental problems through the development of innovative solutions. Some companies go green either to reduce environmental harm or to gain consumer support.

Green startups face additional challenges brought on by their inherent “triple bottom line,” social responsibility, economic value and environmental impact. However, these ventures typically have founders with the passion and drive to rise above challenges, and they can grow fast while helping to protect the health of humanity and Earth. Green startups are attracting venture capitalists and are gaining new support from socially responsible investors, green investors, and popular crowdfunding platforms.
