Global Carbon Budget forecasts CO2 emissions to grow by 2.7% in 2018
06 December 2018Australia: Research by the Global Carbon Budget (GCB) forecasts that CO2 emissions will grow by 2.7% year-on-year to a 37.1 ± 2 Gt CO2 in 2018. This follows a rise of 1.6% to 36.2Gt after a three-year hiatus with stable global emissions. The 2018 forecast is based on preliminary data for the first 6 – 9 months indicate a renewed growth in fossil CO2 emissions based on national emission projections for China, the US, the European Union (EU) and India and projections of gross domestic product corrected for recent changes in the carbon intensity of the economy for the rest of the world.
In 2017 the GCB estimates that cement sector constituted 4% of global fossil CO2 emissions, a rise of 1.2% from 2016. Emissions are expected to grow by 4% in China in 2018, in part due to a 1% rise in cement production. In the EU emissions are projected to fall by 0.7% with stable cement sector emissions. In India emissions are forecast to increase by 6.3% with a 13.4% rise in cement sector emissions.
Fossil CO2 emissions are based on energy statistics and cement production data. The research makes its estimate of emissions from the cement industry using a method adapted from a paper published by Robbie M Andrew of Norway’s CICERO Center for International Climate Research in 2017.
Cement Sustainability Initiative report shows Indian cement industry meeting 2030 carbon emission targets
03 December 2018India: 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: Hoffmann Green Cement Technologies has inaugurated its pilot plant at Bournezeau, Vendée. The 50,000t/yr unit will manufacture cement products using metakaolin and blast-furnace slag, according to the L'Usine Nouvelle magazine. It says it will produce cement with reduced CO2 emissions up to 250kg/t using a flash-calcined process down from 900kg/t in the normal clinker production process. The project had investment of Euro10m.
French cement industry forecasts 3% growth in 2018
15 November 2018France: Bénédicte de Bonnechose, the president of the French cement industry union (SFIC), says that country’s cement market is expected to grow by 3% in 2018. She made the comments whilst unveiling local CO2 reduction targets by 2050, according to the Agence France Presse. The local industry recorded growth of 4% in 2017. She described 2018 as a ‘positive recovery’ with sustained growth following a good first half.
SFIC forecasts that new low-clinker cement products will enter the market by mid-2020. These products include EMC II / CM, EMC VI and LC3 types of cement. These should reduce the CO2 emissions related to current sold cement products by 35%. Other CO2 capture initiatives including Oxyfuel, Leiliac and calcium looping cleanker technologies were also mentioned.
European cement producers not joking about implications of climate change legislation
17 October 2018Well, it turns out that the European cement industry wasn’t kidding when it raised the risks of the climate mitigation on the sector. This week three (!) integrated plants have been earmarked for closure.
Cementa in Sweden said that it was considering closing its Degerhamn plant due to increased environmental regulations. Today, local press in Spain is reporting that Cemex España is planning to shut down two of its plants. These are plants in different parts of Europe with different local market dynamics but both are within the European Union (EU). That’s three plants closing out of 219 in the EU, or a loss of around 1% of production capacity.
Last week’s column on the United Nations’ (UN) Intergovernmental Panel on Climate Change (IPCC) report on Global Warming raised the way the cement sector is tackling climate change and the existing and impending legislation. President of the German Cement Works Association (VDZ) Christian Knell’s opening words at the VDZ Congress in September 2018 seem prescient. He said, “To be able to realise our efforts in terms of climate protection and at the same time not to lose competitiveness, we need research policy-related support for our investment in breakthrough technologies and the corresponding demonstration projects.” The add-on was that the industry needed to focus on how the development of carbon abatement technologies can meet the 2050 climate goals and, specifically, that suitable boundary conditions would have to be created. The press releases accompanying his speech emphasised that, “on-going trends in European emissions trading and the ‘rapidly increasing’ price of CO2 were already today leading to considerable costs for cement manufacturers.”
These words are similar to the comments Albert Scheuer, a board member of HeidelbergCement, made at the Innovation in Industrial Carbon Capture Conference early in 2018 about dividing the mounting environmental costs of cement and concrete between producers and society in general. Considering how much cementitious building materials most people use throughout their lives compared to the relative low price of cement, this argument carries some weight. In addition, the sustainability credentials of concrete buildings through longer lifespan and durability through extreme weather events is another argument that industry advocates such as the Portland Cement Association (PCA) in the US have been hawking in recent years.
Cementa, a subsidiary of HeidelbergCement, blamed anticipated tightening of environmental regulations for its decision. Although it said that the plant had made improvements over the years, the expected difficulty (read: cost) to make further improvements was becoming too hard. Shifting production to the company’s other two plants in the region, Slite on Gotland and Brevik in Norway, will reduce CO2 emissions by 260,000t/yr.
In Spain, the news from Cemex follows a half-year report from Oficemen, the local cement association, that predicted growth for the year but not as fast as previously expected. The problem was that continued declines in the export market, the 13th decline month-by-month in a row, offset the domestic growth. Oficement president Jesús Ortiz also took time to blame rising electricity costs, expected to rise by 20% year-on-year by the end of 2018.
Market issues in Spain aren’t in doubt, but the real question for both Sweden and Spain is whether EU CO2 legislation right now is causing cement producers to shut plants. The CO2 emissions allowance price hit a high of Euro22/t in September 2018, the highest price in a decade. Allowances have stayed below Euro10/t since 2011 and the price has more than doubled in 2018. Throw in the mood music of the IPCC and the trend seems irresistible. How many more plants in Europe are at risk to shut next? No doubt the European cement producers have charts marking the viability of their plants against the CO2 price. This would be a very interesting graph to get our hands on.

Cemex to close two cement plants in Spain
17 October 2018Spain: Cemex España is preparing to close its cement plants at Gádor in Almería and Lloseta in Baleares. It has blamed reduced demand for cement and European regulations on CO2 emissions for the decision, according to the Cinco Días newspaper. The closures will affect 200 employees and the cement producer is has started to hold union discussions. Cemex will retain integrated plants at Morata de Jalón, Alicante, Alcanar, Castillejo Anover and Buñol.
Riding the IPCC rollercoaster
10 October 2018One graph the United Nations’ (UN) Intergovernmental Panel on Climate Change (IPCC) report on Global Warming of 1.5°C didn’t include this week was what happens if the world just doesn’t bother. It’s probably just as well since warming of 1.5°C is likely to happen between 2030 and 2052 at the current rate of climate mitigation efforts. If they had included such as diagram, it likely would have had a ominous red line hurtling skywards like a rollercoaster track just before the screams start.
The giant paper study is really about comparing and contrasting the different impacts and responses to a 1.5°C and a 2°C rise. One taste of what the higher rise threatens is, “limiting global warming to 1.5°C instead of 2°C could result in around 420 million fewer people being frequently exposed to extreme heatwaves, and about 65 million fewer people being exposed to exceptional heatwaves."
The cement industry gets a look-in with an acknowledgment that the sector contributes a ‘small’ amount (5%) of total industrial CO2 emissions. It then breaks the entire industrial sector’s mitigation strategies down to (a) reductions in the demand, (b) energy efficiency, (c) increased electrification of energy demand, (d) reducing the carbon content of non-electric fuels and (e) deploying innovative processes and application of carbon capture and storage (CCS).
Speaking generally, phasing out coal, electrification and saving energy in mechanisms like waste heat recovery is predicted to get industry only so far. Yet from here even skirting over 1.5°C but below 2°C is ‘difficult to achieve’ without the, “major deployment of new sustainability-oriented low-carbon industrial processes.” Such new process include full oxy-fuelling kilns for clinker production, which have not been tested at the industrial scale yet. Likewise, CCS is seen as a major part of keeping warming below 2°C with a target of 3 Gt CO2/yr by 2050. Some reality is present though when the report says that the development of such projects has been slow, since only two large-scale industrial CCS projects outside of oil and gas processing are in operation and that cost is high. It even posits a value of up to US$188t/CO2 (!) for the cost of CO2 avoided from a Global CCS Institute report.
None of this is new to cement producers. The real debate is how to get there without wiping out the industry. In his address to the recent VDZ conference, Christian Knell, the president of the German Cement Works Association (VDZ), highlighted that meeting climate change goals was leading to ‘considerable’ costs for the cement industry. He then called for policy-related support to on-going research projects into CO2 mitigation technology.
The bit that the IPCC doesn’t go into is how much those five steps to the industrial sector will cost cement producers and, vitally, who will pay for it. For example, taking a cement plant’s co-processing rate to 70% and building a waste-heat recovery system, might cost around US$30m. The Low Emissions Intensity Lime And Cement (LEILAC) Consortium’s Calix’s direct CO2 separation process pilot at the Lixhe cement plant in Belgium has funding of about Euro20m. Rolling all three of these measures out to the world’s 2300 cement plants would cost over US$100bn and it would take more than a decade. Beware, the financial figures here are rough estimates and may be way out. The point remains that the implementation costs will not be trivial.
Industry advocates have started in recent years to push back against the climate lobby by highlighting the essential nature of concrete to the modern world. The IPCC barely mentioned this aspect of cement’s contribution to society suggesting recycling, using more renewable materials, like wood, and resorting to the mitigation strategies detailed above. Building new cities out of wood is not inconceivable but CCS seems more likely to solve the climate problem at this stage. Manufacturing the cement that becomes concrete may create CO2 emissions but it has also built the modern world and raised living standards universally. No cement means no civilisation. There is, at present, no alternative.
Instead of leaving this discussion at an impasse, it is worth reflecting on the last week in the industry’s news. An Indian cement company is importing fly ash, several companies are opening or preparing cement grinding plants, a coal ash extraction pilot project is running, a waste heat recovery unit has opened at a plant in Turkey and a producer is getting ready to co-process tyres as a fuel in Oman. All of these stories are proof that change is happening. The trick for policymakers is to keep prodding the cement sector in this direction without disrupting the good things the industry does for people’s lives through sustainable housing and infrastructure.
The November 2018 issue of Global Cement Magazine will include an exclusive article by Mahendra Singhi, the CEO of Dalmia Cement, about his company’s CO2 mitigation efforts.

VDZ president Christian Knell warns of cost of climate change mitigation to cement industry
27 September 2018Germany: Christian Knell, the president of the German Cement Works Association (VDZ), has warned that meeting climate change goals was leading to ‘considerable’ costs for the cement industry. He said that ‘suitable boundary conditions would have to be created’ for climate change issues and noted that on-going trends in European emissions trading and the ‘rapidly’ increasing price of CO2 were leading to mounting costs. “To be able to realise our efforts in terms of climate protection and at the same time not lose competitiveness, we need research policy-related support for our investment in breakthrough technologies and the corresponding demonstration projects,” said Knell.
Knell made the comments during the opening ceremony of the 8th International VDZ Congress 2018 in Duesseldorf. He identified climate protection and digitalisation as key issues for the future of the industry.
Germany: Environmental data from the German Cement Works Association (VDZ) show that average nitrogen dioxide emissions (NO2) from cement production dropped below 300mg/Nm³ in 2017. The value has more than halved since 2000. Other data from the ‘Environmental Data of the German Cement Industry 2017’ report shows that fossil fuels usage by the cement industry fell to 35% in 2017 compared to 45.6% in 2008.
"By consistently promoting the development of clinker-efficient cements, German cement manufacturers are noticeably reducing the carbon footprint as compared to traditional Portland cements," said VDZ President Christian Knell.
Knell also warned that the costs of carbon capture technologies should not be allowed to jeopardise the competitiveness of domestic cement manufacturers and give rise to ‘undesirable’ carbon leakage effects. The industry is currently researching methods to further reduce CO2 emissions such as carbon capture, storage and utilisation techniques, but it is dependent on external financing.
18 German cement manufacturers with a total of 46 cement plants are members of the VDZ. The local industry employs around 8000 people.
Dalmia Cement sets carbon negative target of 2040
18 September 2018India: Mahendra Singhi, the group chief executive officer (CEO) of Dalmia Cement, says that the company aims to be carbon negative by 2040. Singhi made the announcement at the Global Climate Action Summit in San Francisco, US, according to the Indo-Asian News Service. The cement producer is planning to increase its low-carbon product portfolio and use more ‘green’ fuels and raw materials in all of its 14 plants in India.
Dalmia Cement is the first Indian cement company to join RE 100 and it is committed to a target of 100% renewable electricity use. Singhi said that the major challenge is to convert the climate risks into business opportunities while sustaining business growth for the benefit of present as well as future stakeholders. Singhi was previously the Indian co-chair of the Cement Sustainability Initiative (CSI).
Singhi said that Dalmia Group has been able to reduce carbon dioxide emissions to 526kg/t of cement on a group average and to 342kg/t in its eastern operations. According to the CDP (formerly Carbon Disclosure Project) cement sector report in April 2018, Dalmia Bharat achieved the first rank in CDP's low carbon transition league.
