Brazil: Votorantim Cimentos recorded specific CO₂ emissions per tonne of cement of 579kg/t in 2022, down by 3% year-on-year from 2021 levels and by 24% from its 1990 baseline.

The group achieved an alternative fuel (AF) thermal substitution rate of 27% in 2022, compared with 22% in 2021, marking strong progress towards its 2030 target of 53%. Meanwhile, its cement’s clinker factor fell to 74% from 75%, against a 2030 target of 68%.

Votorantim Cimentos’ global director of sustainability, institutional relations, product development, engineering and energy, Álvaro Lorenz, said “Fighting the negative effects of climate change is at the heart of our strategy and aligns with our focus on competitiveness and on creating a positive legacy for society. We continue to work to optimise our product portfolio, explore opportunities in the circular economy and develop new technologies. The improvements in our performance in 2022 reinforce our commitment and ongoing efforts to support the carbon neutral agenda.”

Mexico: Cemex has reviewed its global sustainability and financial performance during 2022 in its Integrated Report 2022. During the year, the group reduced its specific CO₂ emissions by 9% from 2020 levels and by 30% from 1990 levels. It achieved a target of US$1bn-worth of investment in strategic projects over a period begun in 2020. Projects included the execution of water optimisation plans at 20% of Cemex sites in high-water stress areas. Cemex co-processed 27Mt of waste as alternative fuel (AF) in its global cement production - 67 times greater than its own non-recyclable waste footprint - and achieved an AF substitution rate of 35%. Meanwhile, the group also reduced its cement's clinker factor to 74%. Its Vertua reduced-CO₂ concrete range accounted for 33% of its concrete sales. During the year, Cemex launched the world's first net zero, fully electric heavy concrete mixer truck.

In 2022, Cemex recorded sales of US$15.6bn, down by 12% year-on-year, and reduced its debt to US$408m.

France: Vicat and Materrup have formed a joint venture to industrialise production and accelerate marketing of Materrup's Clay Cement 1 (MCC1) raw clay cement. The Le Moniteur newspaper has reported that the technology is based on a precursor and activator mixture which removes the need for calcination of the clay. Materrup said that this halves MCC1 cement's CO₂ emissions compared with ordinary Portland cement (OPC).

The partners say that clay has better long-term feasibility than other alternative raw materials for cement production, because global reserves are currently 2Tnt.

Canada: A court has fined Lafarge Canada US$145,000 for a dust spill from its Bath, Ontario, cement plant in October 2019 that 'covered' homes, gardens and cars. The court found that the emission 'caused or was likely to cause adverse effects.' The Belleville Intelligencer newspaper has reported that the Canadian Ministry of Environment previously concluded that no harm to health resulted from the incident.

Plant manager Ignacio Arroyo said "Myself and our plant team unreservedly apologise for the upset and concern that our dust release has caused all of you. We intend to make it right and make sure it never happens again."

World: The United Nations (UN) has reviewed the progress of initiatives towards the reduction of mercury emissions from cement and other industries under its Environment Programme (UNEP). Mercury is sometimes present in the raw materials and fuel used in cement production. The sector currently emits 2220t/yr of mercury, 11% of global anthropogenic mercury emissions. The UNEP’s Cement Partnership Area aims to ensure ‘globally significant’ emissions reductions. Its priority actions include: establishing sectoral mercury inventories and baseline scenarios, encouraging techniques for the minimisation of mercury releases, increasing awareness in the industry, governments and regulatory bodies and supporting the development of policies in line with the Minamata Convention on Mercury.

The Cement Partnership Area said that it has achieved progress in expanding its cement plant mercury emissions management knowledge base and in reducing emissions. It called on governments to increase funding for projects, the development of new technologies and the publication of guidance documents.

Germany: The Science-Based Targets Initiative (SBTi) has validated Heidelberg Materials' new 2030 CO2 reduction targets. The targets have a base year of 2020 and conform to a 1.5°C climate change framework. Per tonne of cementitious material, the producer is now committed to reducing its Scope 1 CO2 emissions by 24%, its Scope 2 CO2 emissions by 65% and its Scope 3 emissions by 25%.

Heidelberg Materials' chief sustainability officer Nicola Kimm said “As reflected in our updated Sustainability Commitments 2030, climate action is a crucial element of Heidelberg Materials’ sustainability strategy. The SBTi validation shows that our sustainability agenda not only includes the most ambitious reduction target in the cement industry – but also a realistic, measurable plan in line with the 1.5°C scenario. We follow a clear, science-based approach, reducing our carbon footprint through the levers of product and process innovation and industrial-scale carbon capture, utilisation and storage. By closing the carbon and material loops, we will lead the sustainable transformation of our sector.”

In 2019, Heidelberg Materials became the first cement company to secure SBTi validation for its emissions reduction commitments.

Spain: Cemex España will install a carbon capture system at its Alicante cement plant in Valencia, as part of its efforts to make the unit a 'benchmark pioneer low-CO₂' cement plant. The producer holds a contract with ET Fuels for the supply of 45,000t/yr of CO₂ captured at the facility for methanol production.

Chief executive officer Fernando González said “Our goal of reaching net-zero CO₂ emissions is achievable and will be driven by collaboration and innovation. Our decarbonisation roadmap includes reducing emissions to the lowest possible level through proven levers such as clinker substitution and alternative fuels. New levers, such as rapidly developing CCUS initiatives, must effectively tackle the remaining CO₂ emissions to hit our ambitious 2050 objectives.”

India: Dalmia Cement (Bharat) has successfully launched its new fleet of 35 liquefied natural gas (LNG)-fuelled trucks from its Murli cement plant in Maharashtra. The trucks are of two types, covering ranges of 50 - 600km, and will transport bagged cement and bulk raw materials. They have 28% lower CO₂ emissions than conventional diesel-powered trucks, and are thus able to eliminate 840t/yr of CO₂ emissions, while also reducing emissions of nitrous oxides (NO_x) by 59% and particulates by 91%, and eliminating emissions of sulphur oxides (SO_x).

Dalmia Cement (Bharat) says that its next move will be to launch a second fleet of 25 trucks from its Ariyalapur cement plant in Tamil Nadu. By April 2024, it plans to convert 10% of its 3000 truck-strong fleet to LNG fuel.

A spokesperson for the company said “Dalmia Cement has been following the business philosophy of Clean & Green is Profitable and Sustainable. Our overall CO₂ emissions have come down from 670kg/t to 467kg/t – one of the lowest globally – and we are focusing on realising our carbon negative goal by 2040. We are delighted to partner with GreenLine Logistics for further reduction of our Scope 3 greenhouse gas emissions.”

Pakistan: A court has ordered a report by the Environmental Protection Agency (EPA) into alleged breaches of emissions rules at Kohat Cement's Kohat Cement plant in Babri Banda, Khyber Pakhtunkhwa. The Dawn newspaper has reported that alleged dust and chemical emissions from the plant have contributed to a local rise in cases of cancer, asthma and lung diseases, according to complainants.

Residents have filed a petition for contempt proceedings against the EPA and Kohat Cement, as well as local and provincial government authorities. The court previously ordered the EPA to monitor Kohat Cement's emissions in 2018. At that time, it also instructed Kohat Cement to operate its electrostatic precipitators system at all times that cement is being produced. Local residents claim that the plant has continually failed to operate the system.

Mexico: GCC has secured validation by the Science-Based Targets Initiative (SBTI) for its latest CO₂ reduction goals. The group has committed to reducing its Scope 1 emissions per tonne of cementitious product by 31% and its Scope 2 emissions per tonne of cementitious product by 57% between 2015 and 2030. It has also committed to a 37.5% absolute reduction in its products’ Scope 3 emissions over the same period. The goals will serve as sustainability performance targets for GCC’s US$500m sustainability-linked bond, which it issued in January 2022.

GCC's vice president of sustainability and environment Gina Lotito said "We are proud and excited to be a catalyst of progress towards a low-carbon future. Our laser-focus on our climate change strategy and emphasis on reducing CO₂ emissions is a testament to our commitment to creating a sustainable future. While we celebrate our achievements, we acknowledge that there is still much work to be done and remain steadfast in our mission."
