The British government is conducting a study to calculate the carbon dioxide emissions absorbed by concrete,

The British government has commissioned a study to calculate the carbon dioxide emissions that concrete naturally absorbs into buildings and infrastructure in the UK.

The Department for Business, Energy and Industrial Strategy (BEIS) has appointed a consortium led by the Metal Products Association (MPA),

to assess the size of the emissions focal point for carbonation of concrete in the UK.

MPA has worked with Heriot Watt University, Consulting Engineer Ricardo, and The Concrete Society.

The project intends to create the world’s first national greenhouse gas inventory to include a scientific model (Tier 2),

to calculate the benefit of the emissions focus provided by the carbonation of concrete over its life cycle.

Carbonation is a naturally occurring process in concrete in which hydrated minerals react with carbon dioxide from the air to form calcium carbonate.

This project will create a methodology that will inform the UK’s Greenhouse Gas Stock (GHG) and the UK’s national and international reporting commitments on climate change.

Buildings are also responsible for 42% of emissions, either directly from heating or indirectly through the use of electricity.

While this research will determine what the use of concrete in buildings and infrastructure contributes to the absorption

of carbon dioxide into the atmosphere by improving national accounting for greenhouse gases.

The Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) recognized the carbonation of concrete.

But there is still no approved method for calculating the emissions foci associated

with the carbonation of concrete in the 2019 United Nations Framework Convention on Climate Change (UNFCCC).

This research aims to help bridge this gap.

Achieving net production of concrete and cement in the UK does not depend on carbonation;

this natural carbonation has previously been overlooked by national and international carbon accounting.

But it could undoubtedly help industry remove more carbon dioxide from the atmosphere than it emits,

especially when carbonation can be boosted or accelerated.

This important research will help improve carbon accounting in the UK,

by evaluating exposed concrete used in buildings up to bridges.

It will also provide an accurate assessment of carbonization across the life cycle of the built environment.

How buildings and infrastructure are designed to shape the future,

and subsequently use and optimize their use of demolished materials to serve as carbon hotspots and accelerate CO 2 uptake.

The UK concrete and cement industry has developed a roadmap to reduce emissions beyond Net Zero by 2050.

The plans are to meet Net Zero through decarbonized electricity and transmission networks,

fuel switching, and increased use of low-carbon cement and concrete.

As well as the technology of carbon capture, use or storage (CCUS) for the manufacture of cement.
