Foreword
Awareness is growing
of the urgent need to turn
political statements and analytical findings into
climate mitigation action that leads to a more
sustainable future. We can and must change
the path that we are on. Innovative low-carbon
technologies will play a central role in this
transition.
Goal 13 of the United Nations 2030 Agenda for
Sustainable Development,
adopted by world
leaders in September 2015, calls for urgent action
to combat climate change and its impact. The
Paris Agreement, negotiated in December 2015 at
the 21st session of the Conference of the Parties
to the United Nations Framework Convention on
Climate Change, attempts to limit the rise in global
temperatures this century to less than 2°C above
preindustrial levels.
To spark this movement
and build on a long-
standing collaboration, the International Energy
Agency (IEA) and the Cement Sustainability
Initiative (CSI) of the World Business Council for
Sustainable Development (WBCSD) have partnered
to develop this update of the global
Cement
Technology Roadmap
that was produced jointly in
2009 (the first industry-specific roadmap).
The cement industry currently represents about 7%
of the carbon dioxide (CO
2
) emissions globally and is
the third-largest industrial energy consumer. Cement
companies in the CSI have
been long taking action to
reduce CO
2
and voluntarily reporting independently
verified CO
2
and energy performance information
(representing 21% of global cement production). The
analysis for this roadmap is based on a compilation
of performance data and information related to
cement production from the best available data
sources worldwide, a key source being the Getting
the Numbers Right database managed by CSI, which
is
externally verified, as well as other sources.
The vision of this roadmap is based on an energy
system pathway and a CO
2
emissions trajectory
consistent with at least a 50% chance of limiting
the average global temperature increase to 2°C by
2100. In contribution to this effort, the roadmap
uses a bottom-up approach to explore a possible
transition pathway based on least-cost technology
analysis for the cement industry
to reduce its direct
CO
2
emissions by 24% below current levels by 2050.
The outlined transition for such CO
2
emissions
reductions in cement production is ambitious,
and the changes must be practical, realistic and
achievable. The transition of the cement industry
can only be attained with a supportive regulatory
framework and effective and sustained investments.
The roadmap outlines
these policy priorities
and regulatory recommendations, assesses
financial needs, discusses investment stimulating
mechanisms and describes technical challenges
with regard to research, development and
demonstration needs and goals.
While this roadmap focuses on cement
manufacturing, the IEA and CSI recognise the need to
consider CO
2
emissions reduction over the overall life
cycle of cement, concrete
and the built environment
by working collaboratively along the whole
construction value chain. For instance, by optimising
the use of concrete in construction or by maximising
the design life of buildings and infrastructure, further
CO
2
emissions savings can be realised.
This roadmap aims to
contribute to the required
international collaborative effort among
stakeholders, and to be a source of inspiration for
international and national policy makers to support
evidence-based decisions and regulations in support
to the sustainable transition of the cement industry.
