They are looking for a new way of constructing buildings without being so invasive to climate change. What is expected to change and how much pollution buildings create.
At least 70 countries agreed this Friday to review and adapt building construction methods to stop global warming and protect them from climate contingencies, they announced the UN and the French government.
The first “World Forum on Buildings and Climate”which began on Thursday, was co-organized by the UN Environment Agency and the french government and concluded with “Chaillot Declaration”in reference to the palace where the summit ended.

Also searched increase the resilience of buildings to increasing storms, floods and heat waves, especially in the most vulnerable countries in the south. Builders, architects, engineers, design offices, materials or construction industrialists, diplomats or international donors met since Thursday.
Why buildings for climate change are so important
The construction It is a sector “where “Global greenhouse gas emissions continue to rise” and is “not on track to achieve decarbonization by 2050” and respect the 2015 Paris climate agreement (COP21), the statement said.
The ONU foresees a doubling of built surfaces in the world between now and 2060, as well as the almost doubling of raw material consumption, most of which would be dedicated to construction. At the moment the sector is responsible for 21% of global greenhouse gas emissions and of 37% of CO2 emissions related to energy.
Also represents 34% of energy demand and captures half of global raw material consumption, according to the statement. Besides, Demolition and renovation generate 100 billion tons of waste every yearmost of which are not reused, and the 35% end up in areas where they are buried.
Renovation in construction
Among the commitments assumed by the participants is the priority given to renovation over new construction, to reduce the use of non-renewable resources and increase energy efficiency. The statement indicates that it is necessary to save water and energy and reduce air conditioning installations as much as possible.
He also points out that it should favor air circulation inside buildings and develop workforce training to perform this task.
