Grosvenor Britain & Ireland makes Zero Carbon Commitment

Grosvenor Britain & Ireland (‘GBI’) has committed to achieving net zero carbon operational emissions* from all its directly managed buildings, including historic listed buildings** by 2030.

  • Stretching net zero, embodied carbon and broader environmental targets to accelerate behavioural change at historic property business

  • New Supply Chain Charter to deepen industry response and innovations to meet environmental and social imperatives

Grosvenor Britain & Ireland (‘GBI’) has committed to achieving net zero carbon operational emissions* from all its directly managed buildings, including historic listed buildings** by 2030. The business will also report on, and seek to significantly reduce, its embodied carbon emissions - carbon created through associated supply chain and tenant activities. 

To achieve these targets, GBI will eliminate carbon emissions under its control and sustainably design and construct and operate net zero ready buildings, enabling occupiers to reduce or eradicate carbon emissions from their own operations.

It has also today launched a Supply Chain Charter, which commits the business, together with its suppliers, to higher environmental and ethical standards, deepening GBI’s broader contribution to the communities it is active in.

Bold environmental goals are a key pillar of this strategy:

Becoming zero carbon:

  • By 2030, GBI will achieve net zero carbon* operational emissions from all its directly managed buildings, including listed buildings**.
  • GBI will report on, and seek to significantly reduce, the carbon emissions embodied in its supply chain, developments and tenant activity by 2030.
  • The business’ portfolio, including 147 acres of public realm on its London estate, will aspire to be climate positive+ by 2050.

Becoming zero waste:

  • GBI will eradicate all waste from buildings and developments in its control by 2030.
  • By working with customers and stakeholders, the business will aspire to eliminate waste from communities where it operates by 2050.

Valuing nature:

  • By 2030, GBI’s portfolio will have achieved a significant net biodiversity gain, responding to the need to halt the decline of the UK’s wildlife and restore ecosystems.
  • The business will fully map the materials in its supply chain by 2025 to ensure sustainable provenance.
  • GBI aspires to be water neutral by 2050.


Craig McWilliam, CEO, Grosvenor Britain & Ireland, commented: “Recent events simply reinforce our view that companies need to have a wholesale rethink on how they use their influence to halt the worsening impacts of climate change. As one of London’s largest property companies and with a growing business bringing forward large scale housing developments, we recognise the far-reaching impact a change in our behaviour can have.

“While we are on track to halve carbon emissions on our London estate by 2023, many of the tools and technologies needed to help us meet these targets are yet to be developed and tested. To be successful, our commitments will require us to work collaboratively and innovate.

“Through these targets and by working with our supply chain and tenants we can, for example, stimulate the design, construction and operation of zero carbon neighbourhoods at scale.”

Grosvenor Britain & Ireland creates, adapts and manages high quality neighbourhoods for the long-term. The business’ diverse property development, management and investment portfolio includes its historic London estate of Mayfair and Belgravia encompassing landmarks such as Eaton Square, Grosvenor Square, Mount Street and Victoria Coach Station. In addition, it is bringing forward housing developments in London, Oxfordshire and Cambridgeshire including a pipeline of 15,000 homes across new neighbourhoods delivered through its Strategic Land business. 

Supply Chain Charter Launch

Grosvenor Britain & Ireland has already invested in initiatives to help achieve these commitments (see notes). Today the business launches a Supply Chain Charter, which commits the business together, with its suppliers, to higher environmental and ethical standards including:

  • No diesel to be used on the London estate by 2025 and prioritisation of electric equipment.
  • Make a presumption in favour of sustainably sourced materials in design and procurement.
  • Help the business fundamentally change the way its buildings and public realm are designed, constructed and operated.
  • Payment of the Local Living Wage to staff, including apprentices and interns. In 2014, GBI was one of the first UK property companies to pay the London Living Wage to staff and suppliers.  
  • Exclusion of zero-hours contracts, unless requested by the employee.
  • Committing to prompt and fair payment of their own supply chain.
  • Help create inclusive and equitable opportunities for employment in the communities in which GBI is active.


Craig McWilliam added: “If we are truly serious about delivering and accelerating positive change we must partner with those who share our values and ambitions.

“By pushing ourselves to go further, faster these stretching targets will help deliver a better future for the communities we operate in today and future generations. We cannot achieve the change needed alone - together we can achieve more.”

GBI has more than 1,800 suppliers and will expect all to adhere to, and cascade, relevant charter commitments.  The business will work with its partners, and has established a supporting network of expert organisations who will provide advice at no additional cost, to help them achieve the charter’s aims.

Notes to Editors

*The World Green Building Council defines operational net zero carbon as net zero carbon when the amount of carbon dioxide emissions released on an annual basis is zero or negative. A net zero carbon building is a highly energy efficient building that is fully powered from on-site and/or off-site renewable energy sources and offsets. In striving to achieve net zero carbon GBI will only use offsets as the last possible option once all other avenues for reducing emissions have been explored.

** Grosvenor has c1,500 listed buildings on its London estate, of which approximately a third are directly managed.

+Climate positive activity goes beyond achieving net zero carbon emissions to create an environmental benefit by removing additional carbon dioxide from the atmosphere.
