COP21: How construction can help tackle climate change

18 countries and over 60 organizations launch an unprecedented global alliance for buildings and construction to combat climate change.

Ministers from Cameroon, Finland, France, Morocco, Senegal and Sweden, international organizations, multinational CEOs and civil society leaders launch the alliance to speed up and scale up the potential of the sector for climate action.

18 countries (Austria, Brazil, Cameroon, Canada, Finland, France, Germany, Indonesia, Japan, Mexico, Morocco, Norway, Senegal, Singapore, Sweden, Tunisia, Ukraine, United Arab Emirates, United States of America), and over 60 organizations on Thursday launched an unprecedented Global Alliance for Buildings and Construction to speed up and scale up the sector¹s huge potential to reduce its emissions and literally build greater climate resilience into future cities and infrastructure.

The Alliance, which gathers organizations from countries to cities, NGOs, public and private organizations, networks of professionals, of cities, of companies as well as financing institutions, announced the initiative at the Lima to Paris Action Agenda Focus on Buildings, in Paris. Among other members, the International Union of Architects (UIA) now represents, through national architecture organizations, close to 1,3 million architects worldwide; the World Green Building Council (WGBC) represents 27000 companies involved in green buildings business worldwide; the Royal Institution of Chartered Surveyors (RICS) represents 180000 building surveyors globally; the European Construction Industry Federation (FIEC) represents the construction sector employers through 33 national federations in 29 countries.

The buildings and construction sector is responsible for 30 per cent of global CO2 emissions but it also has the potential to avoid about 3.2GtCO2 by 2050 through mainstreaming today’s available state-of-the-art policies and technologies. Reducing energy demand in the building sector is one of the most cost-effective strategies for achieving significant greenhouse gas reductions.

Real estate represents about 50% of global wealth. Creating this transformation requires investing around an additional US$220 billion by 2020 ­ an almost 50% increase on 2014 investment in energy efficient buildings ­ but less than 4% of the current total global annual investment in construction activity ($8.5 trillion/yr). Returns on this investment could be as high as 124% if investments in ambitious policy and technology actions are being made now.

As of today, 91 countries have included elements of commitments, national programs, or projects and plans relating to buildings in their Intended Nationally Determined Contributions (INDCs), the declarations by countries of what they are prepared to commit to.

With support and greater awareness, many more may realize the potential for the building sector to contribute to realizing national targets. Yet, the building sector is very local and needs to align many different actors, which is a primary objective of the new alliance.

As cities keep on growing until more than 70% of the global population will call urban areas home, it becomes crucial for the sector to reduce its emissions and literally build in greater resilience against climate change.

Action will include:

  • minimizing energy demand
  • greening the construction value chain
  • integrating renewables through district energy
  • implementing integrated building design and urban planning
  • engaging financing institutions.

BREEAM’s significant contribution to carbon reduction detailed in new study

Study shows typical BREEAM Excellent building saves in excess of 30% CO2.

A new briefing paper gives an overview of sustainability standard BREEAM’s contribution to global carbon reduction in buildings. Published during global climate change conference COP21, the paper also gives details of how BREEAM has evolved since the standard was created 25 years ago and how it might develop in future so it continues to challenge the industry to go beyond standard practice.

The paper includes an analysis of assessment data (from 2011 onwards) shows that BREEAM assessed buildings achieve an average 22% reduction in CO2 emissions compared to buildings designed to regulatory minimum performance requirements. BREEAM Excellent buildings save more than 30% and Outstanding rated buildings in excess of 50%. To date over 530,000 building and homes have applied the standard in over 70 countries around the world.

‘On Monday over 150 world leaders gathered in Paris to discuss how to drive down carbon emissions and manage rising temperatures due to climate change. Given that buildings and homes together account for over 40% of the UK’s total carbon emissions, it’s more important than ever that standards like BREEAM are used to drive down emissions and reduce running costs over the life time of a building.’ said Director of BREEAM Gavin Dunn.

The paper says that one of the main aims of the BREEAM energy strategy moving forward is to strengthen the links between schemes covering different life cycle stages, with a particular focus on the relationship between the New Construction and In-Use schemes, and opportunities for addressing the ‘performance gap’.

This week BRE made a pledge to reduce further reduce CO2 emissions over the next 5 years by 900,000 tonnes, by certifying a further 9000 commercial buildings to the BREEAM standard. This pledge, together with other pledges from leading organisations in the built environment, forms part of the “Collective Commitment” created by the World Green Building Council as part of COP21.

Copies of the paper and details of BRE’s BREEAM pledge are available at www.breeam.com/cop21.
