As the demand for environmentally preferable products continues to grow and spread around the world suppliers and manufacturers are constantly trying to prove that their products are environmentally friendly. 

The two largest globally recognized programs are BREEAM and LEED®.
So what's the difference?


• BREEAM (Building Research Establishment Environmental Assessment Method) was first established in 1990 in England. 

• BREEAM requires trained personnel to analyze the evidence on the ground against the credits criteria. They then report their assessment to BRE (a building research organization funded mainly by the government) who go ahead to validate the findings before giving certification. 

• BREEAM has been able to adopt to the local market for a long time. If the assessment criteria for a certain location does not quite fit with BREEAM assessment criteria, the assessor can engage BRE to establish a criteria that fits the assessment. LEED® on the other hand does not have such provisions. 


• LEED®  (Leadership in Energy and Environmental Design) was first established in 1998 in the US,  largely inspired by and based on BREEAM. 

• LEED® on the other hand does not require any trained personnel, the certification of the buildings is given by US Green Building Council (USGBC). As a result, BREEAM is said to provide better credits compared to LEED®.

• LEED® gives slightly more importance to the occupant’s health and comfort, while BREEAM is more focused around environmental impacts. For example, LEED® will award you credits for increasing car parks in the building, BREEAM will not.

Choosing to follow either BREEAM or LEED® can sometimes depend on factors such as the type of building, is the building new or existing, the location of the building, etc. 


Both BREEAM and LEED® exist to help mitigate the impact by guiding specifiers towards more efficient and sustainable solutions.
