Green Tourism (was formerly known as The Green Tourism Business Scheme - GTBS) is a national sustainable tourism grading scheme in the UK that has been endorsed by VisitEngland, VisitScotland and VisitWales and has been validated by the International Centre for Responsible Tourism since 2008.
Operated by a not-for-profit organisation, Green Business, there are over 2,300 GTBS members throughout the UK and Ireland.
Businesses are graded by qualified environmental assessors and can benefit from significant marketing advantage and reduced running costs of up to 20%.
Green Traveller has visited and filmed over 100 Green Tourism graded businesses in the UK, writing, photographing and filming the businesses as part of our Green Travel Guides series.
Here's a video that explains how video can be used to to promote green tourism businesses:
