Cemex last week. HeidelbergCement and LafargeHolcim this week. China yesterday. One can’t seem to move for major building materials companies (or their owners) issuing carbon neutral strategies at the moment. This week HeidelbergCement first launched its ‘Beyond 2020’ plan, a mixture of financial, portfolio and sustainability goals. Then, LafargeHolcim said that it had signed a pledge with Science-Based Targets (SBT) towards meeting intermediate targets by 2030. Last night, President Xi Jinping told the United Nations (UN) General Assembly in New York that China was aiming to hit peak emissions before 2030 and carbon neutrality by 2060.

The timing of these various sustainability goals are directly or indirectly linked to Climate Week NYC, a notable annual event on the climate change calendar that is taking place at the moment. So it’s a good time for large-scale industrial CO₂ emitters, like building material producers, to have something positive to say.

China’s announcement steals the limelight given that the country produces around half of the world’s cement and holds a higher share of clinker production capacity. Western media has pointed out the geopolitical implications of Xi’s statement that was delivered shortly after a speech by US president Donald Trump, a notable climate change sceptic. Xi’s speech didn’t contain any details so it may simply have been an attempt to demonstrate global leadership. Yet if the Chinese government makes a go of it, the effect could be profound. Data from the Centre for International Climate and Environmental Research (CICERO) shows that the Chinese cement industry emitted an estimated 782Mt CO₂ in 2018 compared to 1.50Gt CO₂ from the cement industry globally and 37.1Gt CO₂ from all human-related sources. In other words, the Chinese cement industry was responsible for 2% of all CO₂ emissions in 2018. And this industry is mostly owned by a government that has just publicly declared a carbon neutral target.

In some ways the other announcements, by the western-based multinational building material companies, are even more radical since these producers are subject to market forces. These companies don’t have to do this. They also contain more specifics than Xi’s words so far.

HeidelbergCement says it has brought forward its CO₂ emissions target for 2030 of 525kg CO₂/t (specific net CO₂ emissions per tonne of cementitious material) to 2025. That’s a 30% decrease from 752kg CO₂/t in 1990. Its new goal for 2030 is below 500kg CO₂/t. The main emission reduction methods it outlines include: increased use of alternative raw materials and fuels; increased use of secondary cementitious materials to reduce the clinker factor of cement; investment in plant efficiency and CO₂ reduction at the plant level; and increased share of low-carbon concrete products.

Chart 1 above outlines HeidelbergCement’s thinking post-2030 with further reductions to CO₂ emissions mainly achieved through circular economy methods and different carbon capture techniques. Two points to hold in mind here. One: note the current uncertainty about which route will provide the biggest share of the reduction. Two: this chart considers concrete, not cement.

LafargeHolcim’s announcement was that it has joined Science Based Targets initiative (SBTi) ‘Business Ambition for 1.5°C.’ It says that by doing so it has become the first global building materials company to sign the pledge with intermediate targets for 2030, validated by SBTi. This is slightly confusing given that other building materials companies have had different dealings with the SBT as it has worked towards its current scheme. Earlier this month, for example, we reported that Taiwan Cement had started an SBT project in 2019 and had some targets approved by the SBTi in June 2020. Grupo Cementos de Chihuahua (GCC) said it was joining SBTi at the start of 2020 and HeidelbergCement reported its SBTi approved targets in mid-2019. Finally, India-based Dalmia Cement is also on the SBTi ‘Business Ambition for 1.5°C’ list but it is a stretch to describe it as a ‘global’ company.

The core of LafargeHolcim’s statement is a further reduced target for CO₂ intensity in cement of 475kg CO₂/t by 2030. So far it’s decreased its CO₂ intensity by around 23% to 516 kg CO₂/t in 2019 from ~730kg CO₂/t in 1990. There’s less looking ahead after 2030 compared to HeidelbergCement but the measures outlined until then include: more use of low-carbon and carbon-neutral products; increased use of alternative raw materials and fuels; doubling waste-derived fuels in production to reach 37%; greater use of calcined clay and developing novel cements with new binders; and operating the company’s first net zero CO₂ cement production facility.

Many of the various networks and initiatives across the climate action community came together in June 2020 as part of the UN backed ‘Race To Zero Campaign,’ an attempt to align the disparate leading net zero initiatives ahead of the 26th United Nations Climate Change Conference (COP), due to take place in November 2021 in Glasgow, Scotland. This swirl of different net zero schemes also partly explains the confusion over the different organisations backing sustainability targets that companies can sign up to. So it’s a good thing to see closer collaboration here.

More cynical readers will have latched on to president Xi’s opportunity to show up President Trump in the climate change action stakes. They may also prefer news stories about activist investors prompting change at shareholder-owned companies as they increase their portfolios or stories like Morgan Stanley’s announcement this week that it has a new commitment to reach net-zero financed emissions by 2050. If the investment bank actually means it and other financiers follow suit then the fiscal incentives for net zero draw closer and the rest should follow. Moneys talks… and hopefully CO₂ stays buried in the ground.

Switzerland: LafargeHolcim has signed the Science-Based Targets initiative (SBTi) Business Ambition for 1.5°C pledge, which commits it to net-zero carbon dioxide (CO₂) emissions by 2050. Additionally, the company has committed itself to a 20% reduction in its CO₂ intensity between 2018 and 2030.

The company says that over the period it will: “accelerate the use of low-carbon and carbon-neutral products such as ECOPact and Susteno, recycle 100Mt of waste and by-products for energy and raw materials, scale up the use of calcined clay and develop novel cements with new binders, double waste-derived fuels in production to reach 37%, reach net CO₂ emissions 475kg/t of cementitious material and open and operate its first net-zero CO₂ cement plant.

Chief Executive Officer (CEO) Jan Jenisch said, “I believe in building a world that works for people and the planet. That’s why we are reinventing how the world builds today to make it greener with low-carbon and circular solutions. I am very excited to be working with SBTi, taking a rigorous science-based approach to shape our net zero roadmap and accelerating our efforts to substantially lower our CO₂ footprint. I will not stop pushing the boundaries to lead the way in green construction.”

Taiwan: Taiwan Cement has been awarded the first product carbon footprint label by the local Environmental Protection Administration (EPA). It follows its completion of the structure of product category rules (PCR) in early August 2020 and inspection by the EPA. TCC's products will be marked with carbon footprint labels from the fourth quarter of 2020. The Taiwan-based cement producer has also announced support for the Global Cement and Concrete Association’s (GCCA) 2050 Climate Ambition plan.

TCC started its Science-Based Target project in 2019 and says it became the first cement company in the Greater China region to complete target setting and was approved by Science-Based Target initiatives (SBTi) in June 2020. Following the science-based methods promoted by the Intergovernmental Panel on Climate Change (IPCC) from the United Nations, TCC set a target to reduce carbon emissions by 11% in 2025, using 2016 emissions as the base. TCC completed carbon footprint certification for the most popular cement products, Portland Type I cement and Ready-Mixed Concrete 3000psi, in July 2020.

Mexico: Grupo Cementos de Chihuahua (GCC) says it will commit to setting greenhouse gas reduction targets in line with climate science by joining the Science Based Targets initiative (SBTI). GCC will set science-based emission reduction targets in line with the level of decarbonisation required to keep global temperature increase well-below 2°C compared to pre-industrial temperatures, as described in the latest Special Report of the Intergovernmental Panel on Climate Change (IPCC).

“By joining the SBTI, GCC will ensure that the company´s low-carbon transformation is aligned with climate science and is a further reflection of our unwavering commitment to implement global best practices related to sustainability,” said Enrique Escalante, GCC´s chief executive officer (CEO).

Today is the first day of the Global FutureCem Conference taking place in Brussels, Belgium. The event is looking at how the cement industry can adapt to a low or zero carbon world. Although Global Cement is organising the event, it is clearly topical as two news stories this week demonstrate.

Firstly, the chief executive officers (CEO) from 13 US companies, including LarfargeHolcim, announced that they were lobbying the US government to enact business-led climate change legislation. The initiative, known as the CEO Climate Dialogue, included principles such as ‘significantly’ reducing US greenhouse gas emissions. This is shocking because, at face value, large-scale CO₂ emitters like LafargeHolcim have the most to lose from more rigorous environmental regulations. What do they have to gain from doing this? This is like turkeys voting for Christmas!

Interpretations of why LafargeHolcim and others might want to do this could go in a few directions. Firstly, the intention might be fully plausible. These companies could genuinely want to combat climate change. Secondly, more cynically perhaps, leading demands for legislation puts the lobbyists in the room when change is actually made. Given the integral nature of concrete in modern construction this is not necessarily a bad thing. Environmentalists may want to ban building materials that create CO₂ emissions but, until they can offer an alternative or convince people to accept reduced quality of life, then cement is the material of choice. Thirdly, leading change allows one to stay ahead of it or at least give the sector more time to react to it. The ‘turkeys’ may not want to vote for ‘Christmas,’ but perhaps ‘Christmas’ could be replaced with something else?

This latest initiative by the CEOs in the US has parallels with the creation of the Global Cement and Concrete Association (GCCA) in 2018. Like the current moves in the US, cement producers led the creation of the GCCA, to promote concrete as the sustainable building material of choice.

Meanwhile, Germany’s HeidelbergCement also announced this week that its CO₂ reduction targets to 2030 have been assessed against the Science Based Targets initiative’s (SBTi) criteria. Its SBTi target is to reduce scope 1 greenhouse gas (GHG) emissions 15% per ton of cementitious material by 2030 from a 2016 base year. HeidelbergCement has also committed to reduce scope 2 GHG emissions by 65% per ton of cementitious materials within the same timeframe. The SBTi target follows HeidelbergCement’s previous goal of a 30% reduction in its specific net CO₂ emissions by 2030 compared with 1990. It says it has achieved a reduction of 20% so far.

HeidelbergCement is a sustainability leader in the sector with various projects on the go including the Low Emissions Intensity Lime And Cement (LEILAC) consortium direct separation pilot project at the Lixhe cement plant in Belgium. Following SBTi is a continuation of this trend, albeit one that anchors it with a global consensus.

Coincidence perhaps but when the two largest non-Chinese cement producers start announcing sustainability stories like then the picture is changing. The questions at this point is how far will it go.

A full review of the 3rd Global FutureCem Conference will be published after the event. To find it and more information visit: http://www.globalcement.com/conferences/global-future-cement/introduction

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.
