Green Building Accreditations

Sustainability, ESG & Social Value Consultancy

Green Building Accreditations

With 40% of global carbon emissions linked to the built environment and growing regulatory requirements, building certifications like BREEAM, LEED and SKA are crucial to your capital and asset plans. With emerging ESG focus on real estate assets, green building accreditation is a key reportable indicator in frameworks such as the Global Real Estate Sustainability Benchmark (GRESB). Our sustainability experts are here to support you at every step, from estate-wide strategies to project-level certifications.

Work with a partner you can trust

BREEAM (Building Research Establishment Environmental Assessment Methodology) and LEED (Leadership in Energy and Environmental Design) are leading international standards for sustainable buildings, while BREEAM RFO and SKA Ratings are leading standards for refurbishments. RLB’s certified providers have supported hundreds of clients around the world in this field. We are your trusted partner for all aspects of delivery within your tight timescales and budgets.

Attain the best standards

Around the world, a wide range of other building standards can play a crucial role in your ESG performance and path to net zero – from the WELL standard, providing a holistic approach to support health and wellbeing, to NABERS, bringing efficiency to occupant energy use. We can help you understand and implement the building standard that is right for you.

Value & Impact

How we’ve helped others meet their challenges



Guiding NatWest towards net zero

We developed a strategic roadmap for achieving net zero carbon across the retail estate of NatWest, one of the UK’s biggest banks. Our approach, which embedded sustainability into NatWest’s branch refurbishment programme, has already delivered significant carbon reductions, setting a new standard for sustainability in the retail banking sector.

“The RLB sustainability team showed us what holistic good practice looks like when it came to a roadmap towards target net zero. Their knowledge of sustainability within the built environment is very strong, and their innovative approaches have set the bar for our sustainable fit-out practices going forward.”
