18 Countries Launch Unprecedented Global Alliance to Combat Climate Change

On Thursday, 18 countries, and over 60 organizations launched an unprecedented Global Alliance for Buildings and Construction to speed up and scale up the sector's huge potential to reduce its emissions and literally build greater climate resilience into future cities and infrastructure.

Countries involved are as follows: Austria, Brazil, Cameroon, Canada, Finland, France, Germany, Indonesia, Japan, Mexico, Morocco, Norway, Senegal, Singapore, Sweden, Tunisia, Ukraine, United Arab Emirates and the United States of America.

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 percent of global wealth. Creating this transformation requires investing around an additional US$220 billion by 2020 - an almost 50 percent increase on 2014 investment in energy efficient buildings - but less than 4 percent of the current total global annual investment in construction activity ($8.5 trillion/yr). Returns on this investment could be as high as 124 percent 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 percent 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.
