Mexico: Cemex has updated its sustainability-linked financing framework in line with its latest emissions reduction targets of 475kg/t of CO₂ per tonne of cementitious material. Under the new framework, Cemex will issue up to US$350m-worth of sustainability-linked bonds on the Mexican Stock Exchange. The group plans to use the funds to refinance debt, as well as for ‘general corporate purposes.’ It aims to acheive 85% sustainability-linked financing by 2030.

Cemex said "The proceeds will be used exclusively for eligible green projects in pollution prevention and control, renewable energy, energy efficiency, clean transportation, sustainable water and wastewater management, production technologies and processes adapted to the circular economy and/or eco-efficient products.”

US: Heat Battery developer Rondo Energy has concluded a financing round with US$60m raised in investments, Renewables Now News has reported. Investors included Siam Cement Group and Titan Cement Group, as well as Breakthrough Energy Ventures, Energy Impact Partners, the Climate Innovation Fund, Rio Tinto, SABIC, Aramco Ventures, SDCL Energy Efficiency Income Trust and John Doerr. Rondo Energy’s Heat Battery is a means of connecting cement plants and other industrial facilities to a constant supply of electricity ultimately derived from renewable energy sources.

Australia’s Climate Change Minister announced plans this week to look at a potential carbon border adjustment mechanism (CBAM). Chris Bowen told an Australian Business Economists forum in Sydney that policies were needed to ensure a level playing field for Australian firms. Mentioning the European Union’s (EU) CBAM by name, he said that his department would prepare a review to assess carbon leakage risks, develop policy options and look at the feasibility of an Australian CBAM, particularly in relation to steel and cement.

The Antipodean nation has past form when it comes to carbon legislation. Back in 2012 it introduced the Clean Energy Act under the Gillard administration. The legislation was intended to introduce an emissions trading scheme with a carbon pricing scheme. However, it faced opposition from rival political parties and the Cement Industry Federation warned that the local cement sector was vulnerable to overseas competitors outside of the scheme. Job losses followed and Adelaide Brighton appeared to react by focusing more on imports. The Abbott administration then abolished the act in 2014 putting forward its Clean Energy Future package instead, which focused more on investing towards change. Jump forward nearly a decade and the Albanese government passed its Climate Change Bill in 2022. This set legally binding targets, including a commitment to cut CO2 emissions by 43% from 2005 levels by 2030. Bowen’s look at a CBAM is an obvious next step from here, addressing one of the main criticisms of the previous Clean Energy Act.

Local building materials company Boral reacted positively to a CBAM in its annual results released earlier this week with chief executive officer Vik Bansal saying that the company was “...advocating for an effective Carbon Border Adjusted Mechanism for Australia.” He also reconfirmed the group’s commitment to a target of net zero emissions by 2050. However, at the same time, Boral also reduced its emissions reduction target to 2025 from 2019 figures to up to 14% from 19% previously. This was blamed on “external factors” such as delays in securing the required regulatory approvals for the next phases of an alternative fuel program. Mining company Rio Tinto also warned in late July 2023, as part of its half-year financial results, that it might potentially miss its emissions target for 2025 unless it resorted to buying carbon credits.

CBAMs became serious in 2023 when the EU passed its own scheme into law in May 2023. The EU CBAM will now enter into a transitional phase from 1 October 2023 until the end of 2025. During this period importers of goods covered by the legislation will be required to report greenhouse gas emissions (GHG) embedded in their imports (direct and indirect emissions) but they will not have to make any financial payments or adjustments. The system will then enter its full format from 1 January 2026, with affected importers being forced to purchase and surrender CBAM certificates, which will be priced at the EU emission trading scheme (ETS) rate, currently at around Euro88/t. Other CBAMs have also been mooted in Canada and the US. In Canada the government ran a consultation on border carbon adjustments in 2021. It is currently considering its next steps. The US meanwhile has had both Republican and Democrat party senators make separate suggestions for a CBAM since at least 2021.

Just because the EU is set to implement its CBAM and other countries are considering their own versions doesn’t mean that they are necessarily a good idea. Cembureau, the European cement association, has been steadily lobbying on the details such as indirect emissions and waste incineration in the EU CBAM for years. Criticisms of CBAMs in general include potential clashes with World Trade Organisation rules, accusations of protectionism, triggering inflation, not being equitable to less developed nations and even failing to stop carbon leakage in the first place. The EU CBAM has also linked itself to the local ETS price. So, even after the transitional period, the carbon price may start to jump about in unpredictable ways once the system fully goes live in 2026.

The game-changer in recent years for international carbon emissions reduction legislation though was arguably when the US government introduced its Inflation Reduction Act in 2022. This is because it served both sustainability and self-interest on a grander scale than seen previously. The act promised US$369bn in subsidies for companies to invest in low carbon technology. However, the catch was that the investment tied supply chains to the US market, much to the ire of some of the US’ trade partners such as the EU. CBAMs offer a similar opportunity to governments around the world if they choose. They can be used to protect domestic carbon emission reduction effects in heavy industry but they can also be used for protectionism. Hence Bowen was due to say during his speech that the Inflation Reduction Act and other policies elsewhere “mean that Australia needs to act to stay in the game.” Australia has the advantage that it can watch how the EU CBAM pans out before it implements its own version.

Australia: The Ministry of Climate Change, Energy, the Environment and Water is holding a consultation over the possible implementation of a Cross-Border Adjustment Mechanism to penalise imported cement for its CO₂ emissions in line with the Australian cement industry’s emissions reduction goals. The Guardian Australia newspaper has reported that the government expects to publish its report on the policy in mid-late 2024. The government began implementing new CO₂ emissions limits for Australia’s 200 largest industrial emitters in July 2023. It expects these to eliminate 200Mt-worth of CO₂ emissions over the period up to 2030. Climate Change and Energy Minister Chris Bowen said “80% of these companies, and 86% of covered emissions, are covered by corporate net zero commitments.” Australia is committed to net zero CO₂ emissions by 2050.

With regard to the proposed Cross-Border Adjustment Mechanism, Bowen said “It’s a potentially important mechanism to ensure domestic sovereign capability and supply. One of the biggest challenges we face is supply-chain crunches, and any measure which helps us deal with that is a positive thing for the transition.”

Spain: Switzerland-based Synhelion and Cemex España plan to build a new clinker plant near Madrid. The plant will use Synhelion’s synthetic fuel to produce clinker from clay and crushed sand at 1200°C. The fuel consists of a gas produced from green hydrogen and captured CO₂, using solar heat. La Tribune de Genève Online News has reported that Synhelion’s thermochemical reactor further helps to capture CO₂ emissions from clinker production. A study by the Swiss Federal Institute of Technology Lausanne indicated that this can halve the cost of carbon capture at cement plants, to below Euro85/t.

Canada: Lafarge Canada says that it successfully integrated 10,000t of recycled concrete waste in cement production at its St. Constant cement plant in Quebec using its ECOCycle Technology process. The year-long production trial constituted the first phase of Lafarge Canada’s pilot of ECOCycle Technology. The producer says that the achievement solidifies its leading position in North American circular construction innovation. Waste360 News has reported that concrete constitutes 4Mt (40%) of Canada’s 10Mt annual generation of construction and demolition waste.

President and CEO David Redfern said “By reusing construction and demolition wastes in the production of new building materials, we are reducing waste sent to landfill. Across Lafarge Canada, we’re evaluating any opportunity to decarbonise our operations, and circularity is part of this effort. This pilot is critical to demonstrate that we can effectively repurpose concrete waste, which goes a long way to conserve our naturally occurring resources and loops in construction sustainability - building new from old.”

US: UK-based Breedon Group says that it is seeking a ‘beachhead’ acquisition from which to build its own building materials business in the Eastern US. CEO Rob Wood said that the top 10 US building materials companies control 40% of the market there, compared to 75% of the UK market being controlled by five leading companies. The Times newspaper has reported that Breedon Group is due to join the UK’s FTSE 250 share index in September 2023. The producer noted the slow progress of proposed reforms to UK building standards, which it says would enable it to reduce its non-fuel CO₂ emissions by 25%. It also said that the government may fail to co-adopt EU emissions trading scheme (ETS) carbon border adjustment mechanism (CBAM) measures, leaving the UK market more open for third-party exporters of cement and other heavy materials.

Wood said “The North American market has big growth opportunities, backed by the certainty of infrastructure investment.”

Sweden: CemVision has reported the successful conclusion of a large-scale production pilot of its ultra low carbon alternative clinker. CemVision produces the clinker using up to 100% recycled industrial secondary materials from the steel and mining sectors. CemVision says that its production process heats the raw materials using renewable electricity, and without the use of fossil fuels. The alternative clinker offers CO₂ reductions of up to 100% compared with ordinary Portland cement (OPC) clinker. CemVision has opened an invitation to possible collaborators to help scale up production, with a target of hundreds of thousands of tonnes per year.

Chief technical officer Claes Kollberg said "We are a climate-first company, making high performance cement. With our competence and experience, it is our duty to produce the most environmentally friendly cement for each application."

Mexico/Switzerland: Cemex and industrial solar heat specialist Synhelion have achieved constant clinker production on an industrially viable scale using only solar heat. The partners say that this confirms the technology's potential for industrial-scale implementation.

Cemex chief executive officer Fernando A González said “I am convinced we are getting closer to the technologies that will enable net-zero CO₂ cement and concrete production. The solid progress I see here proves that solar cement is not just a dream: it is achievable through continued collaboration, and backed up by rigorous research and testing.”

Australia: Alternative cement and concrete producers have welcomed a new Australian civil engineering standard that allows builders to use reduced-CO₂ geopolymer concrete in infrastructure projects. Wagners, which produces Earth Friendly Concrete (EFC), said that the revision has removed on if its key barriers to wider market acceptance. EFC replaces 100% of cement with supplementary cementitious materials, including ground granulated blast furnace slag (GGBFS) and pulverised fly ash, by virtue of its binder technology. Wagners previously supplied EFC for the London Power Tunnels project in the UK, based on local technical approval-based building codes. The producer now expects a new standard like the Australian one to follow in the EU.
