Three of the world’s major building rating tools have signed a Memorandum of Understanding alongside the UK Green Building Council to try to ensure consistency in approach in different markets.
The memorandum has been signed by BREEAM, LEED and Green Star – respectively developed in the UK. United States and Australia. It has also been signed by the UK Green Building Council.
The agreement is in response to a growing demand for consistency and comparability between the tools, particularly with regards to the way they account for carbon emissions.
The new memorandum will help map out and develop common metrics to measure emissions of carbon dioxide equivalents from new homes and buildings. A working group formed of representatives from each of the rating tools will develop the Metrics and seek to align the tools and provide consistency in measurement and reporting.
Carol Atkinson, chief executive of BRE Global, BRE Global Ltd said: “This is a terrific opportunity for the major international system providers to move towards common carbon metrics.”
Rick Fedrizzi, president, chief executive and founding chairman of the US Green Building Council, said: 'The memorandum sets the stage for true progress by focusing on performance that is measurable and verifiable.
'As we work to alleviate the role buildings play in climate change - nearly 39 percent of greenhouse gas emissions in the United States – it's vital that we are able to measure carbon emissions in a consistent, reliable way.'
Paul King, chief executive of the UK Green Building Council, who is also chairman of the World Green Building Council International Policy Task Force, said: “The way in which we construct and operate buildings accounts for almost half of all carbon dioxide emissions contributing to climate change globally.
'Rating tools like BREEAM, LEED and Green Star have a proven track record in driving significant improvements in performance, and I’m delighted they are now coming together to help create an international language that will enable us to talk with one voice about the vital role green buildings can play in creating a low carbon future.”
Romilly Madew, chief executive of the Green Building Council of Australia, said: “Climate change is a global problem, so it is vital we find a global solution. In Australia, residential and commercial buildings contribute 23 per cent of Australia’s total greenhouse gas emissions.
'This memorandum demonstrates Australia’s commitment to ensuring that buildings play their part in any approach to address climate change.”
Green Star is developed and administered by the Green Building Council Australia, and the LEED rating system is developed and managed by the U.S. Green Building Council and BREEAM is owned by UK based research and education charity the BRE Trust and operated by BRE Global.
