A B-Corporation business is one that goes the extra mile when it comes to being sustainable and eco-friendly. The certification labels an organisation as meeting the highest social and environmental standard of living and working for people and the planet. Only 3500 businesses in the world, spread across 70 countries, have this certification. B-Corp is very hard to get, with a business having to go through a long assessment process and needing to meet lots of different requirements, so it is a huge achievement.
