US: The chief executive officers (CEO) of 13 US companies, including LarfargeHolcim, are lobbying the President and Congress to enact business-led climate change legislation. This initiative, known as the CEO Climate Dialogue, urges the government to put in place a long-term federal policy as soon as possible, in accordance with a set of six guiding principles. The group aims to build bipartisan support for climate policies that it says will, “… increase regulatory and business certainty, reduce climate risk, and spur investment and innovation needed to meet science-based emissions reduction targets.”
Companies involved in the CEO Dialogue include BASF, BP, Citi, Dominion Energy, Dow, DTE Energy, DuPont, Exelon, Ford Motor Company, LafargeHolcim, PG&E, Shell, and Unilever. Four environmental groups have also supplied input to the initiative. These are the Center for Climate and Energy Solutions, Environmental Defense Fund, the Nature Conservancy and World Resources Institute.
The six principles include: ‘significantly’ reducing US greenhouse gas emissions; allowing an effective timeline for reductions that will help capital intensive industries to adjust in an ‘economically rational manner’; instituting a market-based price on carbon; making the policies durable and responsible; doing no harm to the competitiveness of the US economy with particular attention to carbon leakage; and promoting equity. Specifically the initiative says that US policy should ensure the country is on a path to achieve economy-wide emissions reductions of 80% or more by 2050 with ‘aggressive’ short and medium term emissions reductions.
“Tackling the challenge of climate change is no easy task, and as industry leaders, we have an opportunity to join forces to advocate for climate legislation. It is critical we begin to set durable and achievable goals that help safeguard the environment while reducing our carbon footprint,” said Jamie Gentoso, the CEO for US Cement operations of LafargeHolcim.
Germany: HeidelbergCement’s CO2 reduction targets to 2030 have been successfully assessed against the Science Based Targets initiative’s (SBTi) criteria. It says this makes it the first company in the cement sector to have approved science-based targets.
"Our goal is to realise the vision of CO2-neutral concrete by 2050 at the latest. In the coming years, we want to make significant progress in this direction, and the SBTi’s approval is a clear proof of our strong commitment," said Bernd Scheifele, the chairman of the managing board of HeidelbergCement. The group’s CO2 reduction strategy is based on measures on plant and product level. These include improving energy efficiency, and a steadily increasing use of alternative fuels and alternative raw materials.
HeidelbergCement’s SBTi target is to reduce scope 1 greenhouse gas (GHG) emissions 15% per ton of cementitious materials by 2030 from a 2016 base year. HeidelbergCement also commits to reduce scope 2 GHG emissions 65% per ton of cementitious materials within the same timeframe. The SBTi target is consistent with HeidelbergCement’s previous goal of a 30% reduction in its specific net CO2 emissions by 2030, compared with 1990. The cement and concrete producer has achieved a reduction of 20% so far.
The SBTi assesses and validates corporate emissions reduction targets against climate science research. Targets adopted by companies to reduce greenhouse gas (GHG) emissions are considered ‘science-based’ if they are in line with the goals of the Paris Agreement – to limit global warming to below 2°C above pre-industrial levels and pursue efforts to limit warming to 1.5°C.
Switzerland: LafargeHolcim reduced its net CO2 emissions per tonne of cementitious material by 1% year-on-year to 576kg CO2/t in 2018 from 582kg CO2/t in 2017. It said that the improvement was achieved by reducing the clinker-to-cement ratio and consuming less energy per tonne of cement, mostly by using alternative fuels and improving the efficiency of the company’s processes. However, data from its Sustainability Report 2018 shows that both its overall gross and net emissions grew. Its net CO2 emissions from cementitious material increased by 2.5% to 121Mt. At the same time its clinker production rose by 2.7% to 151Mt from 147Mt.
The group increased its treatment of waste-derived resources to 52Mt. its alternative raw material substitute rate grew to 11.2% from 10.7%. It established a new pre-processing facility in Madukkarai in India and upgraded its waste handling capacities in Mexico, Ecuador, Brazil, Argentina, the Czech Republic, Bulgaria, India, Canada, Spain and Germany. It also reduced its freshwater withdrawal for cement production and improved its lost time injury rates.
Belgium: The Low Emissions Intensity Lime And Cement (LEILAC) consortium partners and its external advisory board have held a ribbon-cutting ceremony at its pilot Direct Separation Calciner unit at the HeidelbergCement cement plant in Lixhe. The project started commissioning the unit in March 2019. Testing is now set to start to validate the performance of the pilot.
The European Union’s (EU) verified CO2 emissions figures were released earlier this week on 1 April 2019. The good news is that no cement plant is within the top 100 largest emitters. All the top spots are held by power plants, iron and steel producers and the odd airline. Indeed, out of all of the verified emissions, cement clinker or lime production only represents 7% of the total emissions. Of course this is too much if the region wants to meet its climate change commitments but it is worth remembering that other industries have a long way to go as well and they don’t necessarily face the intrinsic process challenges that clinker production has. If the general public or governments are serious about cutting CO2 emissions then they might consider, for example, taking fewer flights with airlines before picking on the cement industry.
The EU emitted 117Mt of CO2 from its clinker and lime producers in 2018, a 2.7% year-on-year decrease compared to 120Mt in 2017. This compares to 158Mt in 2008, giving a 26% drop in emissions over the decade to 2018. However, there are two warnings attached to this data. First, there are plants on this list that have closed between 2008 and 2018. Second, there are plants that provided no data in 2018, for example, all the plants in Bulgaria. Climate change think tank Sandbag helpfully pointed out in its analysis of the EU emissions data that industrial emissions have barely decreased since 2012. The implication here being that the drop from 2008 to 2012 was mainly due to the economic recession. Sandbag also made the assertion that 96% of the cement industry’s emissions were covered by free allocations in the EU Emissions Trading Scheme (ETS) thereby de-incentivising sector willingness to decarbonise.
By country the emissions in 2018 from cement and lime roughly correspond with production capacity, although this comes with the caveat that emissions link to actual production not potential capacity. So, Germany leads followed by Spain, Italy, Poland and France. Of these Poland is a slight outlier, as will be seen below.

Poland leads the count in the top 10 EU CO2 emitting cement plants in 2018 with five plants. Greece follows with two plants. This list is deceptive as all of these plants are large ones with production capacities of 2Mt/yr and above. As it contains many of the largest plants in the EU no wonder the emissions are the highest. It is also worth considering that there are far larger plants outside of the EU.
In summary, as most readers will already know, the cement industry is a significant minority CO2 emitter in the EU. Countries with larger cement sectors emit more CO2 as do larger plants. So far, so obvious. Emissions are down since 2008 but this mostly seems to have stalled since 2012, bar a blip in 2017. The change though has been the rising carbon price in the EU ETS in 2018. Coincidentally the carbon price has been fairly low and stable since 2012. If the mechanism is working properly then changes should start to appear in 2019. Already in 2018 a few European cement producers announced plant closures and blamed the carbon price. Watch this space.
Spain: Oficemen the Spanish cement association has blamed falling cement exports in 2018 on rising electricity and CO2 emissions prices. The association said the European Union CO2 price tripled to Euro24.60/t at the end of 2018 from Euro7.80/t at the start of the year, with an average price of Euro16.00/t of cement. Exports fell by 12% year-on-year to 8.1Mt in the 11 months of the end of November 2018. Cement consumption grew by 8% year-on-year to 13.4Mt in 2018. It forecasts growth of 3 – 6% in 2019.
Sweden: LafargeHolcim has been named by Sasja Beslik, the head of sustainable finance at Nordea, as the second worst company for increasing CO2 emissions in the five years between 2011 and 2016. Other cement companies in the list that Beslik published via his Twitter account include CRH, HeidelbergCement and Shree Cement. The list, entitled ‘The CO2 Culprits Top 100’, was assembled using data from financial services company MSCI.
UK: The Global Cement and Concrete Association (GCCA) has launched its first six sustainability guidelines. The six guidelines include a number of key performance indicators (KPI) against which full member companies must monitor and report on their sustainability performance across a number of key activities. The guidelines include monitoring and reporting CO2 emissions and other emissions from cement manufacturing, co-processing of fuels and materials, safety and water usage.
“Signing up to the guidelines emphasises the cement and concrete sector’s commitment to sustainable development including its critical work to reducing global CO2 emissions,” said GCCA Cement Director Claude Lorea.
To achieve the extended compliance, full GCCA members will have their data and targets verified and reported publicly. GCCA intends to communicate data publicly in a consolidated format. In November 2018 the GCCA published a Sustainability Charter which set out five key pillars, which it says encompasses the sustainability spectrum of the cement and concrete sector.
Two views on India
12 December 2018Research from the Global Carbon Budget (GCB) this week forecasts that fossil CO2 emissions from the Indian cement industry will rise by 13.4% in 2018. This is in stark contrast to the smooth mood music from the Cement Sustainability Initiative (CSI) last week, which stated that the local industry was on track to meet its commitments towards decarbonisation. So what’s going on?
The situation is akin to the fable about the blind men and the elephant. Both the GCB and the CSI are approaching the emissions of the Indian cement industry from different directions. The GCB is using available data (including data from the CSI) to try and estimate what the CO2 emissions are. It takes cement production data using a method adapted from a paper published by Robbie M Andrew of Norway’s CICERO Center for International Climate Research in 2018 and then it takes into account the types of cement being produced and the clinker factor. This is then converted into an estimated clinker production figure and this is then converted into a CO2 figure.
However, the CSI meanwhile actually has direct data from its local members. At the moment these include ACC, Ambuja Cements, CRH, Dalmia Cement (Bharat), HeidelbergCement, Orient Cement, Shree Cement, UltraTech and Votorantim Cimentos. As part of the Getting the Numbers Right (GNR) database it collects production and sustainability related data from its members. However, for reasons of competition, it maintains a year gap before it reports its data. This means that the GCB can report its estimate ahead of the CSI data.
There is nothing to stop the CSI reporting its progress against its targets though. And this is exactly what it has done in India with the recent document outlining progress towards the 2030 targets from the low carbon technology roadmap (LCTR). The headline CSI metric was direct CO2 emission intensity. According to the CSI, this has fallen by 32kgCO2/t cement to 588kgCO2/t cement in 2017 mainly due to an increased uptake of alternative fuel and blended cement production, as well as a reduction in the clinker factor. This is bang on target with its aim of hitting 320kgCO2/t in 2050 (around 560 kgCO2/t in 2020, assuming a linear decrease).
The problem is that cement production growth in India suddenly sped up in 2018. Global Cement estimates that India’s cement production is set to rise by 7% year-on-year to 296Mt in 2018 from 280Mt in 2017. Data from the Ministry of Commerce & Industry shows that cement production rose by nearly 16% year-on-year to 244Mt in the first nine months of 2018 from 211Mt in the same period in 2017. Along these lines the Cement Manufacturers Association of India has forecast growth of 10% in the 2019 financial year to the end of March 2019. It reckons that this is the fastest growth in the sector since the industry slowed down in 2011.
India’s per capita cement consumption is low (222kg/capita) and its urban population is also low (around 30%). That’s a lot of cement that’s going to be used as it shifts to developed global rates and already it’s the globe’s second biggest cement market. The CSI was right to get in there eight years ago. Yet, the question now is can CO2 emissions decrease whilst the market grows? Research in the US suggests that the real reason for emission drops in the 2010s was the economic recession, not policy shifts or changes in the energy mix. If that holds in India then the cement industry will have a hard time reducing its carbon footprint irrespective of the work the CSI has done.
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.
