Reducing the carbon
dioxide emissions associated with the production of concrete and
its constituent materials can be achieved by improving energy
efficiency and reducing consumption. The indicator (kWh/tonne) also
referred to as ‘energy intensity’ reports energy consumption during
the manufacture of concrete products added to proportional
contributions from each of the constituent materials. This is
effectively a measure of the average embodied energy of all
concrete produced (by the Forum members).
Energy used in production as a proportion of production
In 2015, the energy intensity
figure for the Rolling mix is 133.1 kWh/t. The figure for concrete
and reinforcement is 156.0 kWh/t. The energy intensity figure for
Standardised mix is 122.7 kWh/t. The figure for concrete and
reinforcement is 146.5 kWh/t.
To provide an indicator that more
accurately reflects the performance of the industry, energy
intensity is now also shown as a baseline or standardised mix. This
shows the energy intensity per year, based on the concrete mix of
the 2008 baseline year.
