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.
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.
Australia: Western Australia’s environment minister Reece Whitby has questioned the efficacy of tests submitted by Cockburn Cement in relation to its Munster lime plant in May 2023. The tests showed successes in odour reduction during sand feeding at the plant’s Kiln 6. Business News Western Australia has reported that the government and an independent expert have raised ‘areas of concern’ as to whether the trial represents normal operating conditions for the kiln.
David Scaife, who represents Cockburn District in the Western Australia Legislative Assembly, said "My gripe is not with the workers, it is with the senior management and the directors of Cockburn Cement and its owner, Adbri, who have refused to do the right thing either by moving the lime manufacturing operations to its Kwinana facility or at least making the investments necessary to eliminate the odour."
Bamburi Cement reduces carbon dioxide emissions by 3% in 2022
27 November 2023Kenya: Bamburi Cement reduced its Scope 1 CO2 emissions by 3% year-on-year in 2022. Data from its Sustainability Report for 2022 shows that the subsidiary of Holcim also increased its alternative fuels substitution rate by 6%, according to the Standard newspaper. The company’s managing director Mohit Kapoor attributed the drop in emissions to the increased use of alternative fuels, using alternative raw materials to substitute for clinker, using renewable energy sources and optimisation of the cement manufacturing process. In line with Holcim Group the company has committed to becoming net zero by 2050.
India: Nuvoco Vistas sold 4.5Mt of cement during the second quarter of its 2024 financial year (FY2024), up by 1.2% year-on-year. Its revenues grew by 7% to US$309m, while its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 73% to US$40.4m. The producer achieved specific CO2 emissions of 462kg/t and an alternate fuel (AF) substitution rate of 14%. During the quarter, it completed debottlenecking projects at the Risda, Chhattisgarh, and Nimbol, Rajasthan, cement plants. The company said that these raised its clinker capacity by 2000t/day. It also secured a new patent, for its fibre reinforced cement composition, and introduced its Concreto UNO and Duraguard F2F premium cements on the Jharkhand market.
Managing director Jayakumar Krishnaswamy said “Our value over volume strategy has positively contributed to the company’s performance. Our trade share has increased from 72% in the second quarter of the 2023 financial year (FY2023) to 74% in the second quarter of FY2024. In addition, the results also demonstrate our commitment to managing the dynamic cost environment through an optimised power and fuel mix, between conventional and clean energy sources.” He added “The expansion at the Haryana cement plant is expected to be completed in FY2024, which will enable us cater to strong demand in the Northern India region.”
Philippines: Holcim Philippines has appointed I Squared Capital subsidiary Berde Renewables to build, maintain and operate two rooftop solar power plants, at its Bulacan and La Union cement plants, respectively. The solar power plants will have a combined capacity of 7.8GWh/yr and reduce Holcim Philippines’ CO2 emissions by 5500t/yr. The Business Mirror newspaper has reported that the projects advance the producer’s aim to reduce its energy-related CO2 emissions by 65% between 2018 and 2030.
Holcim Philippines president and CEO Horia Adrian noted the 20% reduction in overall CO¬2 emissions that the company has already achieved up to 2022 and said “This project further strengthens our ability to support Holcim's net zero direction and the country's nationally determined contributions.”

CirCap-led consortium invests in Nanogence
19 October 2023Switzerland: Reduced-CO2 cement catalyst developer Nanogence has secured an undisclosed sum from a consortium of investors led by investment fund CirCap. Nanogence’s catalyst reduces the CO2 emissions of cement production by 40%, without changing production processes. Tech EU News has reported that the catalyst is capable of increasing cement’s strength and durability compared with that of ordinary Portland cement (OPC) produced without it. Prior to the latest financial development, the company had raised US$2.7m-worth of funding.
CEO Abhishek Kumar said “We are excited to receive the support from incoming renowned investors in this essential journey to accelerate the transition towards a low carbon built world. With growing demand worldwide, we need to align with like-minded strong backers for our growth phase.”
India: Dalmia Bharat sold 13.2Mt of cement during the first half of the 2024 financial year (1 April 2023 – 30 September 2023), up by 9.6% year-on-year 12Mt in the first half of the 2023 financial year. This contributed towards a 24% year-on-year rise in the producer’s earnings before interest, taxation, depreciation and amortisation (EBITDA) to US$144m from US$116m in the previous first half. During the first half of the current financial year, Dalmia Bharat commenced commercial production from its new 500,000t/yr Ariyalur clinker plant and 2Mt/yr Sattur grinding plant, both in Tamil Nadu. The former commissioning raised the company’s clinker capacity to 22.2Mt/yr.
Group managing director and CEO Puneet Dalmia said “We see a multi-year-strong cement demand trend continuing, as India is undergoing a large-scale metamorphosis. We were one of the first ones to foresee this upcycle and started building our capacity ahead of time. In the past 3.5 years, we have added 17.2Mt/yr-worth of cement capacity, which is 65% growth over 2020 financial year capacity. In line with our vision to reach 110 – 130Mt/yr by 2031, we are continuing to make consistent strides in that direction and capitalise upon the huge opportunity ahead of us.”
The company’s cement managing director and CEO, Mahendra Singhi, noted the effects of a ‘reduction in fuel prices, increased usage of renewable power and improvement in key performance indicators.’ He added “We continue to demonstrate our commitment towards the environment, as we have further brought down our CO2 footprint to 456kg/t of cement, which is one of the lowest in the global cement sector.”
