Technology Roadmap Low-Carbon Transition in the Cement Industry Key actions to 2030 Actions by all stakeholders are critical for
realisation of the vision laid out in this roadmap
for the cement industry. These are consistent
with at least a 50% chance of limiting the average
global temperature increase to 2°C by 2100 (2DS).
Government and industry must take collaborative
action to create a favourable investment framework
for accelerating the sustainable transition of the
cement industry globally, to achieve the levels of
carbon emissions reductions envisioned. These
actions include the following.
Creating an enabling level playing field
Governments should pursue efforts towards
developing stable and effective international
carbon pricing mechanisms complemented by
interim financial stimulus packages that compensate
asymmetric pricing pressures in different regional
markets. While a considerable proportion of
cement production is not exposed to cross-border
competition, it is crucial that carbon pricing
mechanisms are coupled with measures that ensure
local lower-carbon cement production remains
competitive against higher-carbon cement imports.
Putting technological change into action
All stakeholders should intensify collaborative
action to increase implementation of state-of-the-
art technologies and share best operating practices.
Industry stakeholders should assess, at the cement
plant level,
4
opportunities to use low-carbon
technologies and should develop plant-level action
plans to increase the speed and scale of deployment
of such technologies.
Governments, in collaboration with industry,
should develop legislation to support the use of
fuels that are less carbon intensive in cement kilns.
Cement manufacture provides an efficient use
of waste for heating purposes and incorporates
non-combustible components into a valuable
product compared to landfilling. This is preferable
to using landfill sites or other, less-efficient thermal
treatment methods. Emissions monitoring must be
regulated, and awareness-raising campaigns and
industry training should be enhanced.
4. For example, Cement Sustainability Initiative (CSI) member
companies in India have assessed the potential for implementing
carbon mitigation technologies in a sample of cement plants
to gain site-level insights into the opportunities for wider
deployment at the national level as Phase II of the
Technology Roadmap: Low-Carbon Technology for the Indian Cement Industry (IEA and WBCSD, 2013).
Governments and industry should ensure sustained
funding and supportive risk-mitigating mechanisms
to promote the development and demonstration
of new technologies and processes that offer the
potential for CO
₂
emissions reduction. Immediate
action is required to achieve the commercial-
scale demonstration of oxy-fuel carbon capture
technologies in cement production by 2030, as well
as to gain experience of operating large-scale post-
combustion technologies in cement plants. Public-
private collaborative platforms can be supportive
actors in such exercises.
Governments need to promote market mechanisms
that value the provision of flexibility in the energy
system to stimulate power generation from
renewable sources of energy and power generation
capacity additions based on excess heat recovery
(EHR), in the cement industry.
Facilitating uptake of sustainable products
Governments need to ensure regulations and
standards are in place to enable greater use
of cementitious constituents to lower the
clinker content of cement and to support wider
penetration of blended cements while ensuring
appropriate product performance. Awareness-
raising campaigns, industry training and education
can enhance acceptance by markets and also
widespread dissemination.
Governments and industry should further
collaborate to accelerate the development of
standards and durability testing of alternative
binding materials for cements, to facilitate market
deployment. Joint efforts are also required to review
and establish building regulations and specifications
aimed at achieving carbon neutrality of the built
environment over its entire life cycle, including
during the use phase and at end of life.
