UAE/UK: The Global Cement and Concrete Association (GCCA) has welcomed the launch of the Canada/UAE co-led Cement Breakthrough Initiative at the COP28 climate conference in Dubai on 6 December 2023. Prior to the launch of the initiative, the GCCA hosted a roundtable for representatives of the cement industry and governments.
GCCA chief executive officer Thomas Guillot said "We support and welcome the launch of the Cement Breakthrough Initiative. Cement and concrete are essential for so much of our modern world and will also be needed for meeting the challenges ahead. They will play a key role in providing resilient and sustainable infrastructure and safely housing communities around our planet. Our member companies are fully committed to a net zero future – and it will take the combined efforts of industry and government to deliver on this commitment. This is the decade to deliver, and we are delighted to work with the Cement Breakthrough Initiative and the government of Canada to accelerate the transition."
Update on cement at COP28
06 December 2023The Global Cement & Concrete Association (GCCA) has been cheerleading at the 2023 United Nations Climate Change Conference (COP28) in Dubai this week with the release of a progress report on the sector’s work towards reaching net zero by 2050. The headline figures are that net CO2 emissions per tonne of cementitious material fell by 23% in 2021 compared to 1990 based on Getting the Numbers Right (GNR) data. Energy efficiency improved by 19% and the fossil fuel component used by the cement sector has fallen to 80% from 98% in 1990. The GCCA has described 2020 - 2030 as the “decade to make it happen” and has set some targets to back this up. Its members intend to reduce CO2 emissions per tonne of cement by 20% by 2030 compared to 2020 levels and concrete CO2 emissions per m3 by 25% over the same time-frame.
The new developments for the cement sector at COP28 so far have been the launch of separate but apparently similar initiatives to help decarbonisation through coordination between nations. The Cement Breakthrough Agenda, backed by the government of Canada and other partners, follows the creation of the Breakthrough Agenda at the 2021 United Nations Climate Change Conference (COP26) whereby designated governments lead so-called ‘Priority Actions’ to decarbonise various sectors. The idea is to collaborate on measures such as policies, regulations and technologies to help reduce the cost of future investment in decarbonisation. The priority actions will be developed in 2023, worked towards in 2024 and then revised on a regular basis thereafter. The German Chancellor Olaf Scholz also launched the so-called ‘Climate Club’ on 1 December 2023 to help developing nations invest in technologies to decarbonise sectors such as cement and steel production. The intention is to set up the technical groundwork for a standardised calculation of CO2 intensity in selected products, such as cement and steel, set definitions on what net zero is for these sectors and then set up a platform to connect countries with funding and technical support from governments and the private sector. Neither the Cement Breakthrough Agenda nor the Climate Club has mentioned funding though.
Additionally, Holcim announced that it had become a founding member of the Sustainable Markets Initiative’s SMI Circularity Task Force. The group aims to promote the circular economy to the private and public sector. Holcim was keen to point out that it is already recycling nearly 7Mt/yr of construction and demolition waste, with a target of 10Mt/yr pencilled in by 2025.
Other groups are not as upbeat as the GCCA though. The Global Carbon Project, for example, has estimated in its annual Global Carbon Budget that global fossil CO2 emissions are set to rise by 1.4% year-on-year to 36.8Bnt in 2023. This figure includes both the CO2 released by cement production and the CO2 uptake from cement carbonation. Ongoing research by Robbie Andrew, a greenhouse gas emissions scientist at the CICERO Center for Climate Research in Norway and the Global Carbon Project, found that process emissions by the cement sector fell for the first time since 2015 in 2022, to reach 1.61Bnt. This decrease was most likely due to China’s falling cement production in 2022, stemming from a downturn in the local real estate sector. However, both the data from GCCA and the Global Carbon Project may be right simultaneously as they look at the emissions of the cement sector in different ways.
The GCCA’s job is to advocate for the cement and concrete sector and it is presenting itself well at COP28. Since its formation, it has set up roadmaps, encouraged collaboration and innovation, and is now reporting back on its progress. Net zero remains the goal by 2050, but the GCCA is being upfront about the role carbon capture, utilisation and storage (CCUS) is expected to play after 2030 and the lack of any full-scale CCUS units so far. Yet it is tracking what has happened so far through the Green Cement Technology Tracker in conjunction with Leadership Group for Industry Transition (LeadIT).
As for the rest of COP28, various reports have been aired in the international press about whether the conference will call for a formal phase out of fossil fuels in some form or another. Whether it actually happens is another matter entirely, especially considering that the president of COP28 is the chief executive officer of the Abu Dhabi National Oil Company, and any eventual language would likely be vague. Yet the work by the GGCA and others has started to make the unthinkable a little more thinkable.
Cemex launches 1000th reduced-CO2 truck
05 December 2023Mexico: Cemex has reached 1000 reduced-CO2 trucks in operation across its global cement business. This includes trucks fuelled by renewable diesel and natural gas. These efforts have reduced its global transport CO2 emissions by 5% since 2020, in line with the group’s commitment to a 30% reduction by 2030.
Chief executive officer Fernando González said “Our net-zero transition is supported by proven and readily-available lower-carbon technologies that guarantee that we meet our short and medium-term decarbonisation commitments. At the same time, we remain at the forefront of innovation and emerging transportation technologies so we can achieve our ultimate goal of becoming a net-zero CO2 company by 2050.”

Global Cement and Concrete Association publishes Cement Industry Net Progress Report 2023
04 December 2023World: The Global Cement and Concrete Association (GCCA) has published its Cement Industry Net Progress Report 2023. The report highlights the work of the GCCA and its members to lower their CO₂ emissions since signing the 2050 Net Zero Roadmap in October 2021. Initiatives include carbon capture and storage, renewables and alternative materials. These strategies have contributed to a 23% decline in cement and concrete’s CO2 emissions between 1990 and 2023.
GCCA president and Cemex chief executive officer Fernando González said “We are pleased to present this report, which captures the progress our industry is making towards net zero. But it will take the combined efforts of industry, governments and societies around the world to deliver on this commitment.” He added “This is the decade to deliver, and my number one priority is to facilitate the GCCA roadmap levers, designed to make full decarbonisation of our industry possible.”
The Cement Industry Net Progress Report 2023 is available here on the GCCA’s website.
UAE: Emirates Steel Arkan (ESA) has appointed consultancy A³&Co. to help plan and implement decarbonisation initiatives at its 5.7Mt/yr Al Ain cement plant in Abu Dhabi. The collaboration will focus on reducing CO2 emissions and costs, in line with the Science-Based Targets Initiative (SBTi)’s 1.5° Pathway for Net Zero and in conformity to the EU’s Carbon Border Adjustment Mechanism (CBAM).
ESA is committed to reducing its CO2 emissions by 40% between 2018 and 2030, and to achieving carbon neutrality by 2050.
Paebbl trials 100t/yr carbon-storing cement reactor
