Uganda: Security provider G4S has installed solar powered laser security systems for Hima Cement at one of its plants and several mines. The system was commissioned in March 2021 and it uses chargeable solar cells in perimeter security towers. G4S says that the system will improve sustainability and reduce costs compared to conventional alternatives. Where sensors detect a breach, security guards will investigate using electric bikes. The supplier says that the bikes facilitate more covert operations compared to motor vehicles, in addition to having sustainability benefits.

Head of technology Samuel Tebandeke said “We wanted to challenge ourselves to think of a better solution for our customer. We knew that we wanted to introduce electronic perimeter security to enhance the protection for the three mines and the cement plant we protect. Other providers were proposing laying many kilometres of cabling underground to provide power for their electronic perimeter monitoring, but our team decided to investigate a greener solution.”

Canada: St Mary’s Cement plans to apply for a licence to substitute alternative fuel (AF) for a part of its coal, gas and petcoke fuel mix. The plant previously held a two-week AF substitution trial in May 2011. CBC News has reported that the subsidiary of Votorantim Cimentos will present its plan at an evening meeting for the general public on 18 November 2021. The company says that it plans to implement similar AF arrangements to those at its Bowmanville plant, where it uses 90,000t/yr of biomass, wood from construction and demolition and non-recyclable paper and plastics.

Environmental manager Ruben Plaza said "Lower CO₂ emissions is the first consideration and, equally as important, the material has to be approved and available in sufficient quantities with a reliable and sustainable long-term supply."

Climate activist Greta Thunberg memorably summarised the outcome of the 2021 United Nations (UN) Climate Change Conference (COP26) as “blah, blah, blah” but what did it mean for the cement and concrete industries?

Making sense of the diplomatic language the UN uses is a full time job due to its impenetrable jargon. This is partly why climate activists and others may have become jaded about the outcome of the world’s biggest climate change jamboree. The conference of the parties (COP) tried desperately to hang on to the 1.5°C warming aim set at the Paris event (COP21) in 2015. This is dependent though on countries sticking to their 2030 targets and becoming net-zero by 2050 or earlier. Unfortunately, both China and India, two of the world’s current top three CO₂ emitters, have announced net-zero dates of after 2050. Those two countries also drew fire in the western press for weakening the language used in the COP’s outcome document about the ‘phasing out’ or ‘phasing down’ of coal use. However, simply getting coal written on the final agreement has been viewed as a result. Other positive outcomes from the event included commitments for countries to review their 2030 targets in 2022, progress towards coordinating carbon trading markets around the world and work on adaptation finance from developed countries to developing ones.

The headline results from COP26 carry mixed implications for the building materials sector. The Paris agreement (COP21) has already achieved an effect in the run-up to COP26 by prompting the cement and concrete industries to release a roadmap from the Global Cement and Concrete Association (GCCA) in October 2021. Now it’s down to whether individual governments actually follow the targets and how they enforce it if they do. If they don’t, then the response from building material producers is likely to be mixed at best.

What may have a more tangible effect is the work on carbon markets at COP26. Countries were finally able to complete technical negotiations on the ‘Paris Agreement Rulebook,’ notably including work on Article 6, the section that helps to govern international carbon markets and allows for a global carbon offsetting mechanism. The European Union (EU) Emissions Trading Scheme (ETS) has shown over the last year how a high carbon price may be able to stimulate companies to invest in mitigation measures such as upping alternative fuels substitution rates and developing carbon capture and storage/utilisation projects. Critics would argue that it may simply be offshoring cement production and closing local plants unnecessarily. Making a more global carbon trading scheme work amplifies both these gains and risks. Either way though, having an international framework to build upon is a major development. Finally, work on adaptation finance could have an effect for cement producers if the money actually makes it to its destination. The big example of this announced at COP26 was a US$8.5bn fund to help South Africa reduce its use of coal. It is mainly targeted at power generation but local cement producers, as a major secondary user of coal, are likely to be affected too.

Alongside the big announcements from COP26 lots of countries and companies, including ones in the cement sector, announced many sustainability plans. One of these included the launch of the Industrial Deep Decarbonisation Initiative (IDDI) during COP26 by the governments of the UK, India, Germany, Canada and the UAE. This scheme intends to create new markets for low carbon concrete and steel to help decarbonise heavy industry. To do this it will disclose the embodied carbon of major public construction projects by 2025, aim to reach net zero in major public construction steel and concrete by 2050, and work on an emissions reduction target for 2030 which will be announced in 2022. Other goals include setting up reporting standards, product standards, procurement guidelines and a free or low-cost certification service by 2023.

All of this suggests that the pressure remains on for the cement and concrete sector to decarbonise, provided that the governments stick to their targets and pledges, and back it up with action. If they do, then the industry will remind legislators of the necessity of essential infrastructure and then continue to ask for financial aid to support the development and uptake of low carbon cements, carbon capture and whatever else. Further adoption of carbon markets around the world and global rules on carbon leakage could help to accelerate this process, as could adaptation finance and global standards for low carbon concrete. The next year will be critical to see if the 1.5°C target survives and the next decade will be crucial to see if global gross cement-related CO₂ emissions will actually peak. If they do then it will be a case of ‘hip hip hurrah’ rather than ‘blah blah blah’.

Brazil: Members of the Brazilian National Cement Industry Association (SNIC) have committed to a 34% reduction in the CO₂ emissions of their cement production to 375kg/t by 2050 from 564kg/t in 2019. Ten cement producers including Cimento Tupi, CSN Cimentos, InterCement and Votorantim signed the commitment. With the industry's forecast rate of growth in cement production capacity, this will result in possible total CO₂ emissions of 45Bnt in 2050 compared to 36.7Bnt in 2020.

Planned CO₂ emissions reduction investments before 2032 are US$637m across the industry.

Spain: Cementos Molins has secured a renewal of its sustainability-linked loan until December 2026 and increased its limit to Euro300m. The loan is linked to reductions in Cementos Molins’ CO₂ emissions.

Chief financial officer Jorge Bonnin said “This innovation, together with the robust financial position and the strong cash generation, enables the development of the profitable and sustainable growth strategy through markets consolidation and development in new markets.”

Colombia: Dow Jones has named Grupo Argos in its Sustainability Index 2021, the company’s ninth time appearing in the ranking. It achieved its highest ratings in materiality, risk management, environmental reporting, climate change strategy, social reporting and human rights. The group said that the listing constitutes its recognition as the most sustainable cement company in the world. Its sustainable initiatives include offering collection of its used cement bags, supplying all the electricity for its Colombian operations from renewable sources and currently having three credit facilities linked to environmental, social and governance indicators.

Legal and sustainability vice-president Maria Isabel Echeverri said “At Argos, we are greatly satisfied with this result which places us as a world benchmark in sustainability and reassures our commitment to closing gaps and implementing best practices in social, environmental, financial and corporate governance matters. This drives us to continue moving forward in creating social value to build the dreams of housing and infrastructure for millions of people.”

World: The governments of Canada, Germany, India, the UAE and the UK have signed a commitment to support the development of markets for low-carbon cement and concrete in their countries. The governments will create market incentives for purchasers, review and update product standards to allow low-carbon materials to be used in all safe settings and promote their use through their public sector tendering rules.

World Cement Association (WCA) chief executive officer Ian Riley said “I’m delighted to see that governments are heeding our call for urgent action to accelerate decarbonisation of the cement industry around the world, and we look forward to hearing more details from the UK, India, Germany, Canada and UAE on the steps they will take.” He added “This commitment marks a hugely significant shift in mindset that we hope will be followed by other countries in the months ahead. When it comes to hard-to-abate industries like cement, it is vital to work together with governments to create the conditions in which we can get to net zero and beyond, as quickly as possible. We cannot do this alone in time.”

UK: SigmaRoc has announced the ratification of its Greenbloc cement-free concrete block’s environmental credentials with an Environmental Product Declaration (EPD). The EPD is a Type III environmental declaration with ISO 14025, providing full-lifecycle information on the product’s impacts. Greenbloc, an ultra-low carbon alternative to traditional concrete blocks, is the first product of its kind.

Managing Director Michael Roddy said “With the launch of Greenbloc, we believe that we can now offer architects, contractors and housebuilders a competitive, reliable and – thanks to our EPD certification – proven low-carbon alternative to ordinary Portland cement (OPC) blocks. Making the switch from traditional blocks to Greenbloc can reduce the embodied carbon of a typical three-bedroom house by 73%, saving the equivalent of 2.7t of CO₂ per dwelling. It is also worth noting that we have obtained additional third-party test results against the declaration of performance certificate.” He added “The world is changing for the better, and technology is facilitating greater accessibility to materials that can bring about meaningful change for the construction industry. The reception for Greenbloc has already exceeded all expectations, and we are incredibly excited for the potential it has to offer.”

Switzerland: Holcim says it wants to reach at least 40% of sustainable financing by 2024. It intends to put climate action, water preservation and safety at the heart of its strategy to do this. The company has linked this commitment with the completion of two new sustainability-linked financing transactions worth above Euro2.8bn. It has also joined the United Nations Global Compact (UNGC) Chief Financial Officers (CFO) Taskforce alongside 60 companies representing a combined US$1.7Tn in market capitalisation. The UNGC CFO Taskforce aligns members’ finance strategies with the United Nations Sustainable Development Goals (SDG).

Holcim’s CFO Géraldine Picaud said, “Sustainability is at the core of what we do. That's why we set ourselves some of the most ambitious goals in our industry. Walking the talk, we are putting climate, water and safety at the heart of our financing strategy. To make a bigger impact, I am delighted to be a member of the UNGC CFO Taskforce to move this agenda forward with my peers.”

In August 2021, Holcim refinanced a Euro3bn syndicated credit line linking it to climate and safety in line with the UN SDGs. The cost of the credit facility will depend on the company’s achievement of its annual targets in these areas. In September 2021, Holcim placed a new 10-year US$100m sustainability-linked bond, based on its 2030 CO₂ reduction target. This issue represents its first private placement of a US Dollar medium-term note linked to climate action. The investor will be entitled to a higher coupon should the company not meet its climate objective. These actions follow the company’s Euro850m sustainability-linked bond issued in November 2020.

India: Dalmia Cement plans for 100% of its cement to be low carbon by 2031. The company has a US$405m carbon capture and utilisation (CCU) investment plan to help it to realise its goal. It will also undertake carbon offsetting measures.

Business Line News has reported that the company plans to spend US$1.35bn to increase its installed cement capacity by 52% to 50Mt/yr from 33Mt/yr before the 2024 financial year.
