Three major companies are backing a global campaign which aims to ensure all buildings are net zero carbon emissions by 2050.

Engineering firm Integral Group, international property and infrastructure group Lendlease and product manufacturer ROCKWOOL Group have joined the World Green Building Council’s (WorldGBC) initiative as official sponsors.

The goal of the Advancing Net Zero project is the means by which the building sector is to help deliver on the Paris climate deal, the WorldGBC states.

It encourages national Green Building Councils which own and operate certification schemes to introduce or adopt a net zero certification scheme for their market, with a pilot version ready for January 2018.

A total of 11 GBCs are currently participating in the project.

Terri Wills, CEO of the World Green Building Council, said: “The support of major companies such as Integral Group, Lendlease and ROCKWOOL demonstrates the huge appetite amongst businesses to design, build, invest in and operate net zero buildings. We’ve started to pave the path towards net zero and there’s no turning back until every building gets there before 2050.”
