The NetZero Roadmap sets out a pathway for Autoclaved Aerated Concrete (AAC) products to reach net-zero emissions by 2050 with the potential to become carbon negative, thereby absorbing more carbon dioxide from the atmosphere than they produce.

The roadmap aligns the European Autoclaved Aerated
Concrete Association (EAACA) and its members with
the objectives of the Paris Agreement to limit global
warming to 1.5°C and supports policies to decarbonise
Europe’s buildings and construction sectors.

AAC is a lightweight, yet strong and durable building
material that offers ultra-efficient thermal insulation,
optimum fire protection, and a high load-bearing
capacity. With its net-zero roadmap and the potential
to become carbon negative, AAC has a role to play as
a building material in helping to reduce the life-cycle
emissions of Europe’s buildings.

The roadmap sets out the main levers that must
be applied to achieve this. We have drawn these
from known technologies and have based our netzero
target on a life-cycle analysis provided by
an independently verified Environmental Product
Declaration. As the majority of CO2e emissions come
not from the manufacture of AAC itself, but from the
manufacture of two key raw materials – cement and
lime – the roadmap draws on the decarbonisation
pathways published by global and European cement
and lime industry associations.

The building and construction sectors account for a
significant share of Europe’s greenhouse gas emissions
that contribute to climate change. Through this
roadmap, the EAACA and its members are committed
to achieving net-zero emissions in AAC products by
2050 and supporting the development of a climateneutral
Europe.

The EAACA

The European Autoclaved Aerated Concrete Association
(EAACA) represents the interests of producers of autoclaved aerated concrete (AAC) and their national associations across Europe. Founded in 1988, EAACA has members from  19 countries operating more than 100 production sites and producing 17.5 million m3 of AAC per year, enough to build about 400,000 homes.
