World: A Systems Change Lab report on the state of climate change action has warned that the global cement industry is making insufficient progress towards its 2030 climate change targets and that a step-change in action is required. It recorded the carbon intensity of global cement production at 635kgCO₂/t in 2018 with the 2030 target of no more than 370kgCO₂/t. The rate of change over the previous five years was reported as being 2.9% but an annual rate of change of 22.5% would now be required to meet the 2030 target.

It also noted that emissions intensity from the cement industry had actually increased slightly in recent years. It reached this conclusion by using a different methodology from the Getting the Numbers Right (GNR) project. Instead it estimated the global emissions intensity by using global data on process emissions and energy data from the International Energy Agency and the GNR.

The report said that the cement sector would need to go beyond traditional mitigation options such as improving energy efficiency and switching fuels to meet its climate commitments. However, carbon capture utilisation and/or storage (CCUS) and novel cements were described as costly and immature. In its view, “Decarbonisation in the long term thus will depend on significant investments in research, development, and demonstration, alongside efforts to create a demand for low-carbon cements and policies to support investment in decarbonisation technologies.” It described both strategies as, “not yet fully mature in terms of technology development, costs and scaling.” The ‘critical enablers’ it identified to help the cement sector meet its target included stricter regulations, increased demand for low-carbon cement and investment in pilot and industrial scale projects looking at novel cements.

Overall, the report said that change towards averting climate change across 40 key areas in power generation, buildings, industry, transport, land use, coastal zone management and agriculture was not happening fast enough and that none were on track to meet their respective 2030 targets. Change was happening but not at the required pace. Systems Change Lab is a collaboration between the High-Level Climate Champions, Climate Action Tracker, ClimateWorks Foundation, the Bezos Earth Fund and World Resources Institute.

Mexico: Cemex says that Carbon Trust has validated its roadmap to decarbonise global operations in line with the Sectoral Decarbonisation Approach (SDA) 2-degree scenario (2DS) developed by the International Energy Agency (IEA). The validated roadmap is intended to help the company to achieve a 35% reduction of net carbon emissions by 2030. The findings validate Cemex's roadmap for reducing Scope 1 and 2 emissions.

The Carbon Trust has assessed the technical feasibility of the plan based on guidelines defined by international institutions including the International Energy Agency, the Cement Sustainability Initiative, and the European Climate Research Alliance. The CO₂ reduction methods include the use of alternative fuels, using decarbonated raw materials, renewable power projects, and novel cements, among others. The validation also included a review of Cemex's commitment to implement the scheme based on governance mechanisms and business planning.

“The magnitude and complexity of change required by a company such as Cemex to decarbonise its global operations is significant. Our assessment provides the organization’s management, investors and stakeholders with an independent validation that its commitments are backed up by sound assumptions and planning,” said Aleyn Smith-Gillespie, Associate Director Advisory at the Carbon Trust.

One of the summer news stories in the UK has been the drama surrounding the near-failure of dam near Whaley Bridge in Derbyshire. Concrete slabs on an overflow spillway fell away after a period of heavy rain leading to fears that the dam could fail inundating the area. Around 1500 local residents were evacuated for about a week as a precaution until the reservoir’s water level could be pumped down low enough for inspection.

No one was hurt in the incident but it has raised questions about the maintenance and renewal of infrastructure and how this fits with changing weather patterns caused by anthropogenic climate change. A sadder example of this is the collapse of the Morandi Bridge in Genoa, Italy in August 2018 that killed 43 people. This was later blamed on decaying steel rods in the structure. There have been similar debates in the US with President Donald Trump’s on-going attempts to push through a US$2tn infrastructure bill to repair the country’s structures. Although, predictably, it is floundering on the question of who is actually going to pay for it all.

In the UK, for example, cement production hit a high of over 15Mt in the late 1980s before declining to a low of 7.6Mt in 2009 and eventually climbing to above 9Mt/yr since 2015. A big cause of that decline was the 2008 financial crash and the subsequent government austerity policies. Yet, even with this taken into account, production was at around 11Mt/yr in the 2000s. How much, if any, of this production capacity gap of at least 4Mt between the late 1980s and the 2000s might be needed to maintain the country’s infrastructure? Southern Mediterranean countries like Spain and Italy offer even starker examples. Italy’s cement production fell to 19.3Mt in 2017 from nearly 40Mt in 2001. Spain’s production hit a high of around 50Mt/yr in 2007 with apparent production (local consumption and exports) falling to around 20Mt in 2018. Much of these declines are due to loss of export markets but the same basic questions remain about how much capacity will be required in the future to maintain and repair existing structures in developed nations. This could be imported but the usual constraints about moving heavy building materials around inland mean than at least some of this cement will need to manufactured locally.

The International Energy Agency (IEA) estimated in 2010 that the world would need 50Bnt of cement between 2015 and 2030. The global cement industry was already producing around 3.5Bnt/yr in 2015 according to the Global Cement Directory 2015 giving it overcapacity even then towards the estimated target. Global production capacity is just under 4Bnt/yr today. Estimates for the cost of global infrastructure requirements in this period range from US$1Tnr/yr to US$6Tnr/yr. The majority of this will go towards new infrastructure in developing countries but a minority portion will be required for maintenance. One study by the Brookings Institution and the Global Commission on the Economy and Climate estimated that developed countries would need around US$2Tn/yr for their infrastructure bills.

A study by management consultants McKinsey & Company in late 2017 reckoned that there was a worldwide US$55Tn spending gap between then and 2035 for infrastructure spending. It estimated that countries like the UK, Germany and the US needed to increase their annual spending on infrastructure as a percentage of gross domestic product (GDP) by 0.5%. Although Italy only needed to improve by 0.2%. Looking at the change in infrastructure investment rates suggests that the European Union (EU) actually started to improve its investment from 2013 to 2015 by 0.2% but that the US did not.

All of this goes to show that the show is definitely not over for building materials producers in developed countries. These industries may be mature but they should not be complacent. Roads need patching up, bridges need replacing and all sorts of other infrastructure projects are required even in places that have them already.

India: UltraTech Cement aims to increase contribution of so-called ‘green energy’ to 25% of its total power consumption by 2021 from 10% at present. It also intends to raise its contribution of renewable energy to its total power consumption by five times in the next two years to 2021 to over 10%. By building capacity for renewable power the cement producer intends to become one of the largest users of renewable energy in the Indian cement sector.

In addition to renewable energy, the green energy contribution includes energy generated through waste heat recovery systems (WHR). During its 2019 financial year UltraTech commissioned 28MW of WHR systems to take its total generation from WHR to 8% of total power consumption. Further upgrades are expected to be completed in a phased manner by 2021, taking its WHR share to 15% of its total power requirement.

“To bring the cement sector in line with the Paris Agreement on climate change, UltraTech Cement’s annual emissions will need to fall by at least 16% by 2030. There are a number of solutions for reducing emissions associated with cement production as identified by the latest Low Carbon Technology Roadmap published by International Energy Agency (IEA) in partnership with Cement Sustainability Initiative (CSI). These solutions need to be deployed at scale to meet the decarbonisation challenge,” said K K Maheshwari, the managing director of UltraTech Cement.

UltraTech Cement has set a target to reduce its CO₂ emissions by 25% from its 2005 – 2006 level by 2021. The company is also working on CO₂ reduction strategies including energy efficiency, alternative fuels, WHR, renewable energy and reducing its clinker ratio.

Brazil: The National Union of Cement Industry (SNIC) and the Brazilian Portland Cement Association (ABCP) have launched a Cement Technology Roadmap to 2050. SNIC president Paulo Camillo Penna said that the document would help the local industry cut its carbon footprint in the medium and long term. The roadmap was developed with the International Energy Agency (IEA), the Cement Sustainability Initiative (CSI) of the World Business Council for Sustainable Development (WBCSD), the International Finance Corporation (IFC) of the World Bank and a group of academics led by José Goldemberg.

The roadmap intends to reduce specific CO2 emissions by over 30% to 375kg CO2/t of cement in 2050. Key actions to 2030 include strengthening national and international cooperation, promoting new cement standards, raising the clinker substitution rate, promoting the use of alternative fuels in compliance with the National Policy on Solid Waste (PNRS), sharing best practive in energy efficiency and promoting resaerch and development in new greenohuse has mitigation technologies.

India: A report by the Cement Sustainability Initiative (CSI) shows that the local cement sector is on track to meet its 2030 targets from the low carbon technology roadmap (LCTR). Direct CO₂ emission intensity fell by 5% in 2017 in the Indian cement sector compared to the 2010 baseline. CO₂ emission intensity, including onsite or captive power plant (CPP) power generation, was reduced by 6.8% compared to the 2010 baseline. The alternative fuels thermal substitution rate (TSR) increased by 5 times from 2010 to 2017. The sector consumed more than 1.2Mt of alternative fuels in 2017.

“Sustainability is a journey, not a destination. In our globalised and interconnected world, no one can solve alone the challenges ahead of us and the only opportunity to succeed is through collaborative partnerships, where the common interests of all are considered as more important than the sum of individual interests. This is exactly the spirit that has animated the CSI’s low carbon journey since 1999. This flagship project - with its members - has developed, implemented and shared collective solutions for measuring, reporting and improving its greenhouse gas reduction performance, year after year,” said Philippe Fonta, managing director CSI.

The CSI and the International Energy Agency (IEA) worked with nine local CSI member companies - ACC, Ambuja Cements, CRH, Dalmia Cement (Bharat), HeidelbergCement, Orient Cement, Shree Cement, UltraTech and Votorantim Cimentos - to carry out the status review on the sector’s performance trends, continuous implementation measures and notable achievements based on the milestones set in the 2013 LCTR. The Status Review Report was developed in consultation with Confederation of Indian Industry (CII), with support from International Finance Corporation (IFC) and the Cement Manufacturers Association (CMA).

The findings of the report show that the direct CO₂ emission intensity was reduced by 32kgCO₂/t cement to 588kgCO₂/t cement in 2017 mainly due to an increased use of alternative fuel and blended cement production, coupled with a reduction in clinker replacement factor. However, the study also shows that significant efforts will be needed to meet the 2050 objectives of 40% reduction. The CO₂ emission intensity (including onsite or CPP power generation) has reduced by 49kgCO₂/t cement to 670kgCO₂/t cement in 2017 compared to the baseline year. The report has highlighted the adoption of waste heat recovery (WHR) systems by local cement plants.

The alternative fuels TSR increased to 3% in 2017 from 0.6% in 2010. More than 60 cement plants in India have reported continual usage of alternative fuels, with 24% of the total alternative fuels consumed as biomass. The share of blended cements used in the total quantity of cement manufactured increased to 73% in 2017 from 68% in 2010, largely due to the market’s growing acceptance of blended cement, emerging awareness of sustainability concepts, the availability of fly ash from thermal power plants and the use of advanced technology. The production of Pozzolana Portland Cement grew to 65% in 2017 from 61% in 2010. The share of Portland Slag Cement in cement production remained flat, at less than 10%, over the same period. The clinker factor reduced to 0.71 in 2017 from 0.74 in 2010.

In August 2018 the Global Cement and Concrete Association (GCCA) said it was taking over the work previously done by the CSI from 1 January 2019.

France/Switzerland: A technology roadmap by the Cement Sustainability Initiative (CSI) and the International Energy Agency (IEA) sets out a combination of technology and policy solutions that could reduce CO₂ emission from the cement industry by 24% by 2050. The Low-Carbon Transition in the Cement Industry report updates the first global sectoral roadmap produced in 2009. It aims to identify and develop international collaborative efforts and provide evidence for public and private sector decision-makers to move towards a more sustainable cement sector that can contribute to long-term climate goals.

“The first exercise carried out in 2009 had demonstrated its added value to help the sector identify solutions and enablers to reduce its CO₂ emissions and it was essential to adjust this projection with the latest robust emissions data from the CSI’s Getting The Numbers right (GNR) database and the potential of latest technologies developed by the European Cement Research Academy (ECRA),” said Philippe Fonta, managing director, CSI of World Business Council for Sustainable

Development (WBCSD).The report aims to present a way to help the cement industry play its part it meeting the IEA’s 2°C Scenario (2DS) by 2050, which seeks to limit average global temperature increases to 2°C. The report forecasts that global cement production is set to increase between 12 - 23% by 2050 due to rising global population and urbanisation. Despite increasing efficiencies, direct carbon emissions from the cement industry are expected to rise by 4% globally by 2050 under the IEA Reference Technology Scenario (RTS), a base case scenario that takes into account existing energy and climate commitments under the Paris Agreement. The CSI and IEA argue that the low-carbon transition of the cement industry can only be reached with a supportive regulatory framework as well as effective and sustained investments. They say that meeting the RSI requires more investment, with a

potential doubling to meeting the 2DS. Governments, in collaboration with industry, can play a determinant role in developing policy and regulatory mechanisms that unlock the private finance necessary for such a boost in investment.The roadmap uses a bottom-up approach to explore a possible transition pathway based on least-cost technology analysis for the cement industry to reduce its direct CO₂ emissions in line with the IEA’s 2DS. Reaching this goal, the CSI and IEA say, would require a combination of technology solutions, supportive policy, public-private collaboration, financing mechanisms and social acceptance.

Improving energy efficiency and switching to alternative fuels, in combination with reducing the clinker content in cement and deploying emerging and innovative technologies like carbon capture and the use of alternative binding materials are the main carbon-mitigation methods available in cement manufacturing. Further emissions savings can be achieved by taking into account the overall life cycle of cement, concrete and the built environment. The roadmap outlines policy priorities and regulatory recommendations, discusses investment stimulating mechanisms and describes technical challenges with regard to research, development and demonstration.

Switzerland: The Cement Sustainability Initiative (CSI) has published a technology review on current and anticipated developments that can be used to mitigate CO₂ emissions in cement production. The report includes 52 individual papers on existing technologies and seven additional summary papers

The CSI initiated a review of its original technology papers, which were originally developed in 2009, when the sector issued the first ever low-carbon technology roadmap in partnership with the International Energy Agency (IEA), following the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement. The European Cement Research Academy (ECRA) and a stakeholder consultant processes have also supported the project.

Key technological fields covered in the current review include: thermal energy efficiency, electric energy efficiency, use of alternative fuels, materials and biomass, reduction of the clinker content in cement, new binding materials, CO₂ capture and storage (CCS), and CO₂ use (CCU). The report also includes an assessment of the level of possible implementation, the challenges and costs of these technologies in future scenarios for 2030 and 2050.

“The publication of these revised and new technical papers sets robust foundations for the overall exercise of updating our 2009 roadmap. It is also a major step in the implementation of commitments made by the cement sector in Paris through the Cement Low Carbon Technology Partnerships initiative (LCTPi) and it demonstrates that the business is more than ever focused on supporting the implementation of the Paris Agreement,” said Philippe Fonta, managing director of the CSI.

The CSI and IEA plan to share the initial results of the updated global technology roadmap for the cement sector at COP 23 in Bonn, Germany.

Brazil: The International Finance Corporation (IFC) has signed an agreement with the National Union of Cement Industry (SNIC) and the Brazilian Portland Cement Association (ABCP) to support the preparation of the Cement Technology Roadmap in Brazil. The project is being developed in partnership with the International Energy Agency (IEA) and the Cement Sustainability Initiative (CSI). It will be technically coordinated by Professor José Goldemberg, a former Minister of Education and former Secretary of Science and Technology.

In addition to co-financing the initiative, IFC will also use its experience to help produce two of the project's technical studies: energy efficiency and the use of alternative fuels. IFC’s present portfolio includes 30 investments and 10 advisory projects in the cement sector in 26 countries. IFC has already invested more than US$4bn in the sector globally and US$838m in Latin America.

The Brazilian edition of the Cement Technology Roadmap will map current and future technologies and their potential for energy efficiency improvement and greenhouse gas emissions reduction per tonne of cement produced up to 2050. Its main objective is to contribute to the development of the cement industry in Brazil towards a low CO₂ economy, using technical solutions allied to a range of recommendations from the academic, government and financial sectors.

Four major themes are being analysed by the Cement Technology Roadmap - Brazil, which includes the direct participation of major academic and research institutions from various regions of Brazil. They are: Energy efficiency; the use of alternative fuels for co-processing; the use of additions to replace clinker; and the capture, storage and use of CO₂.

Worldwide, two other studies on the cement industry have been previously carried out using the same methodology and with the same partners (IEA and the World Business Council for Sustainable Development) - the global Cement Technology Roadmap, in 2009, and the Low Carbon Technology Roadmap for the Indian Cement Industry, in 2013. The latter was also supported by IFC.

The Brazilian project was launched in September 2014 and is expected to be completed in the first half of 2017. The preparation of the Cement Technology Roadmap - Brazil is being supported by more than 90% of the country’s cement producers.
