US: The Portland Cement Association (PCA) reports that cement consumption rose by 3.6% year-on-year in the first 11 months of 2021. Ed Sullivan, Senior Vice President and Chief Economist at the PCA, made the announcement at the World of Concrete trade fair in Las Vegas, Nevada. He also forecast that cement consumption would be driven by non-residential and public works in 2023 and 2024 as mortgage rates increased. The country is also set to spend US$1tn on new and rehabilitated infrastructure projects and this would consume 46Mt of cement over a five-year program. Over a quarter of this amount would be used on roads, bridges and resiliency structures.

The PCA’s president and chief executive officer Mike Ireland and Senior Vice President of Sustainability Rick Bohan also spoke at the event to further promote the association’s Roadmap to Carbon Neutrality.

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’.

US: The Portland Cement Association (PCA) has published a roadmap to carbon neutrality for the cement and concrete sectors by 2050. It says that the strategy document demonstrates how the US cement and concrete industry, along with its entire value chain, can address climate change, decrease greenhouse gases and eliminate barriers that are restricting environmental progress. It added that the document is a ‘major step’ towards engaging US policymakers, industry partners and non-government organisations.

“Cement and concrete have been pivotal in building resilient, durable and sustainable communities that enable people to live safe, productive and healthy lives via structures that withstand natural and man-made disasters,” said PCA President and chief executive officer, Michael Ireland. “The PCA is uniquely positioned to lead the industry-wide ambition to achieving carbon neutrality and enable our member companies and industry partners to continue building a better future.”

The PCA’s roadmap outlines a number of reduction strategies across the various phases of the built environment including production at cement plants, construction including designing and building and everyday infrastructure in use. It also recognises five main areas of opportunity: clinker; cement; concrete; construction; and carbonation (using concrete as a carbon sink).

Notably goals include a reduction of coal and petcoke use at cement plants to 10% in 2050 from 60% at present, a clinker ratio of 75% in 2050 from 90% at present and a reduction of the CO₂ intensity of concrete of 60% by 2050. The roadmap also noted the necessity of carbon capture and storage/utilisation (CCUS) for reducing CO₂ emissions from cement production. However is pointed out that there are no commercial-scale CCUS installations at any cement plant within the US, location and permitting challenges remained and that infrastructure investment would be required to deal with the captured CO2.

World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).

Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO₂ emissions by 2030 and the elimination of 4.9Bnt of CO₂ emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.

GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”

South Korea: Sampyo Group has announced a planned investment of US$171m before 2030 to reduce Scope 1 and 2 CO₂ emissions by 35% over the period from an August 2021 baseline. The parent company of Sampyo Cement plans to achieve this in the first phase by increased its use of alternative fuels, improving energy efficiency, introducing low-carbon raw materials such as fly ash and developing sustainable products. The company is targeting net zero CO₂ production by 2050.

Canada: The Cement Association of Canada (CAC) and the government have published a joint statement detailing their plant to develop a roadmap to net-zero carbon concrete. When launched in December 2021, the roadmap will provide Canadian cement producers with the policies, tools and technologies to contribute to the achievement of net-zero concrete by 2050. The plans will cover areas including: supporting the low-emissions building materials supply chain, building an innovative opportunities framework and engaging stakeholders. According to the statement, the roadmap will offer total potential CO₂ reduction of 15Mt by 2030, and 4.0Mt/yr thereafter.

The partnership will establish a CAC-led Industry-Government Working Group in collaboration with the National Research Council the Standards Council of Canada and Innovation, Science and Economic Development. Among its tasks will be the publication of updated environmental product declarations.

Australia: Adbri says it wants to achieve net zero carbon emissions by 2050 as part of its commitment to a low carbon future. The board and management team are assessing medium and long term emissions reduction options and are intend to release a roadmap by the 2022 annual general meeting. Adbri set its current emissions reduction target in 2019, to deliver a 7% reduction in its greenhouse gas emissions by 2024 against 2019 baselines. In 2020 it achieved 2.3% reduction.

“We recognise that process emissions from the production of cement and lime are not easy to abate. Adbri is committed to maintaining its sector leadership position in sustainability by continuing to increase its use of renewable energy, alternative fuels and supplementary cementitious materials. Developments in technology and partnership with industry, government and research institutions will be critical as we deepen our understanding of long term emission reduction options. This will form part of our roadmap toward net zero by 2050,” said Adbri’s chief executive officer Nick Miller.

Switzerland: The Swiss cement association Cemsuisse has published Roadmap 2050, a plan for the achievement of net carbon neutrality by 2050. As part of the plan, the association says that Swiss cement producers will launch carbon capture and storage (CCS) installations at their plants from 2030. Individual companies’ plans also involve the reduction of products’ clinker factors and alteration of cement kiln fuel mixes.

Cemsuisse lobbied the government to approve producers’ mining permits in order to prevent an increase in imports from 686,000t in 2020. The figure corresponds to 15% of the nation’s 4.70Mt consumption.

Spain: The Spanish cement association Oficemen has targeted a 43% emissions drop by 2030 across its entire value chain compared to 1990 levels. The objective has been published as part of the association’s sustainability roadmap to 2050. It is a tightening of the previous target of 27% by 2030. Oficemen intends to meet the tougher reduction by using the so-called 5C approach - clinker, cement, concrete, construction and built environment, and (re)carbonation – as detailed by Cembureau, the European Cement Association. Oficemen also revealed that it is working with the Spanish Technological Platform for CO₂ (PTECO₂) on identifying potential locations for storing captured CO₂. Hugo Morán, Secretary of State for the Environment, participated remotely with the launch event.

Oficemen also reports that Spanish cement consumption fell by 12% year-on-year to 12.2Mt in the first 11 months of 2020. Exports declined by 5%.

Germany: The German Cement Works Association (VDZ) has published a study entitled ‘Decarbonising cement and concrete: a CO₂ roadmap for the German cement industry,’ detailing the planned transformation to cement industry-wide carbon neutrality by 2050.

The study says that a decarbonisation scenario based on conventional reduction measures would cut carbon dioxide (CO₂) emissions by 36% between 2019 and 2050. Chief executive officer (CEO) Martin Schneider said that the sector is already “reaching the limits of its potential for any further reduction in the volume of CO₂, particularly as the process-related emissions specifically associated with clinker production cannot be lowered by employing conventional means." As such, the association proposed a “completely new approach to the production of cement and its use in concrete” in order to realise full climate neutrality. It proposes that cement producers help to reduce concrete’s clinker factor, capturing the remaining CO₂ from necessary cement production.

Schneider said, "We have placed the decarbonisation of cement and concrete at the heart of our activities. It will be essential to achieve an integrated approach, incorporating the entire construction value chain.” In order for this more radical scenario to work, he added, “Another essential factor will be to involve society as a whole in this process."
