Spain: Oficemen, the Spanish cement association, has released its roadmap for reducing CO₂ emissions to 2050. The document highlights the potential of new technologies, including carbon capture and storage (CCS), which could decrease the CO2 footprint of the Spanish cement industry by up to 80% in 2050. Using existing the technology the association estimates it could reduce emissions by 35% from a 1990 baseline.

Germany: HeidelbergCement and Aachen University of Applied Sciences (RWTH Aachen) have started a three-year research project ‘CO2MIN’ that started on 1 June 2017 examining the absorption of CO₂ from flue gas by olivine and basalt. The intention is that the carbonised minerals could be used as a value-added additive in the production of building materials. HeidelbergCement and RWTH are supported by the Potsdam Institute for Advanced Sustainability Studies (IASS) and the Dutch start-up Green Minerals. The Federal Ministry of Education and Research (BMBF) is funding the project with Euro3m.

"We are already reducing the CO₂ emissions of our plants very successfully by using alternative fuels and raw materials and by optimising the efficiency of our kilns," said Jan Theulen, Director of Alternative Resources at HeidelbergCement. He added that binding CO₂ in minerals was one approach the company was exploring to reduce its emissions further.

In the first year the research project will focus on the investigation of different minerals in small-scale experiments. The carbonation of the most suitable minerals will then be tested under process conditions in the second year. The experiments will be conducted by the institute of Process Metallurgy and Metal Recycling (IME), which is the coordinator of the RWTH group. Life-cycle assessments (RWTH) as well as analyses of economic aspects and social acceptance (IASS) complete this project phase. In the third year, marketability and acceptance will be further optimised through intensive cooperation with customers.

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.

France: The European Parliament has voted to approve a proposal by the European Commission to reduce carbon credits by 2.2%/yr from 2021 in its Emissions Trading Scheme (ETS). This is an increase from the 1.74% reduction specified in existing legislation. It will also double the capacity of the 2019 market stability reserve (MSR) to absorb the excess of credits or allowances on the market.

Members of the European Parliament (MEP) want to review the so-called ‘linear reduction factor’ with the intention to raising it to 2.4% by 2024 at the earliest. In addition MEPs want to double the MSR’s capacity to mop up the excess of credits on the market. When triggered, it would absorb up to 24% of the excess of credits in each auctioning year, for the first four years. They have agreed that 800 million allowances should be removed from the MSR as of 1 January 2021. Two funds will also be set up and financed by auctioning ETS allowances. A modernisation fund will help to upgrade energy systems in lower-income member states and an innovation fund will provide financial support for renewable energy, carbon capture and storage and low-carbon innovation projects.

The draft measures were approved by 379 votes to 263, with 57 abstentions. MEPs will now enter into negotiations with the Maltese Presidency of the European Council in order to reach an agreement on the final shape of the legislation, which will then come back to Parliament.

Environmental campaign group Sandbag has complained that the new proposal fails to hold to the European Union’s (EU) emissions reduction targets by 2030 that were signed as part of the Paris Agreement in 2016.

“Unless the Council intervenes to substantially strengthen the System, the EU ETS will now become simply an accounting mechanism, leaving meaningful climate action to happen elsewhere. The fact that the carbon price is unchanged as a result of the vote, still at a paltry Euro5, speaks volumes. Without being realigned with real emissions levels in 2020, the EU ETS may well end up existing for 25 years by 2030 without giving the any substantial impetus to decarbonisation,” said Rachel Solomon Williams, Managing Director at Sandbag.

Belgium: Cembureau, the European cement association, has lobbied members of the European Parliament with its opinion that the European Union (EU) Emissions Trading Scheme (ETS) must maintain free allowances at the level of best-performers in order to achieve real emission reductions whilst maintaining a competitive industry in Europe. It expressed its views ahead of a scheduled vote in the plenary session of the Parliament in February 2017. One of its key demands was that fairness should be a key principle of policy making and that jobs in one sector are just as important as those in other sectors.

Cembureau called for the proposal to amend the EU ETS to ensure that all energy-intensive industries are on the carbon leakage list and all installations receive a free allocation based on ‘ambitious but realistic’ benchmarks, and benefit from free allocation based on actual production. It wants a sufficient number of free allocations for energy intensive industries at risk of carbon leakage to be made available, hence the auction share should not be higher than 52%. It also wants no further burden to be imposed on EU-ETS sectors. The 43% reduction objective and the 2.2% linear reduction factor for phase IV should not be further increased. Lastly, it has asked for support for innovation focus on energy intensive industries with an extension to cover the whole range of low carbon technologies including industrial carbon capture and utilisation (CCU). The Innovation Fund should be fully financed from the auctioning share.

In response to an amendment made by the Environment, Public Health and Food Safety committee (ENVI) the cement association said that it did not believe that this proposal could work. Its main concerns were: that introducing such a mechanism with a consequential loss of free allowances could create legal uncertainty and hamper further investments by the cement sector in Europe; that it would be impossible to measure the CO₂ performance of third country producers; an overall lack of clarity as to how such scheme would operate; serious concerns about World Trade Organisation (WTO) compatibility; that application to a few sectors would only lead to discrimination in the downstream market where cement competes with other building materials (steel, glass, wood, asphalt) that are not subject to such a scheme; and that the suggested scheme would lead to a competitive disadvantage for European cement producers on export markets where local cement players are not subject to similar CO₂ constraints.

Cembureau also used the opportunity to highlight some of the research projects the local sector is undertaking to improve its environmental performance, reduce CO₂ emissions and improve energy efficiency.

UAE: Union Cement’s waste heat recovery project has been recognised by the Dubai Carbon Centre of Excellence (DCCE) for reducing CO₂ emissions in Dubai in 2016. Local projects under the emirate’s Carbon Abatement Strategy achieved an emissions reduction of 419,500t of CO₂ in 2016 saving nearly US$1.4m, according to comments made by DCCE to the Gulf Today newspaper. Other projects that contributed to the saving included the Dubai 13MW Photovoltaic Plant and Dewa Energy Efficient Chillers. The DCCE promotes Dubai’s transition to a low-CO₂ green economy and is responsible for monitoring the levels of CO₂ emissions in the Emirate.

Egypt: The Egyptian cement industry could reduce its CO₂ emissions by 2030 by following new recommendations in a report from the European Bank for Reconstruction and Development (EBRD). These recommendations have been published in the EBRD’s report, ‘Policy roadmap for a Low-Carbon Egyptian Cement Industry,’ which highlights the need for decisive and collaborative action by the industry’s stakeholders in order to achieve a reduction in CO₂ emissions.

“Improving environmental standards in the cement industry and offering commercial incentives is realistic and vital for the profitability of the sector,” said Philip ter Woort, the EBRD Director for Egypt.

The roadmap outlines recommendations for policy actions from the Egyptian government that may provide effective incentives for the cement industry to improve its energy efficiency and to reduce CO₂ emissions. The report points out that the potential for improvement is high despite that 50% of the Egyptian cement industry’s production capacity was built after 2000, and is using up-to-date equipment and clinker kilns that use best available technology (BAT).

Until 2014, the Egyptian cement industry, one of the most energy intensive industries in the country, had primarily used state-subsidised natural gas and heavy fuel oil to fire its cement kilns. However, following a gradual phasing out of the energy subsidies, Egyptian cement companies have switched to using high CO₂ intensive fuels such as coal and petcoke.

The roadmap suggests that in order to reduce CO₂ emissions, the industry should reduce the clinker content in cement, increase the use of alternative fuels, improve electrical energy efficiency and use more renewable sources of energy. Under one of the more ambitious scenarios, 2.2Mt/yr of coal will no longer have to be imported by 2030, saving about US$200m. Furthermore this would lead to a reduction in CO₂ emissions to about 2% below the historic level prior to the fuel switch. In addition the cement industry could increase its usage of alternative fuels substitution.

The report was initiated by the EBRD, in cooperation with Egypt’s Ministry of Industry and Trade, the Egyptian Environmental Affairs Agency (EEAA), the Chamber of Building Materials Industries/Cement Industry Association (CBMI) and the Cement Sustainability Initiative (CSI) of the World Business Council for Sustainable Development (WBCSD).

Germany: HeidelbergCement has released its seventh Sustainability Report so far. Highlights from the report include a reduction of specific net CO₂ emissions by 22% to 606kg/t of cement (compared to 1990 levels) and a decreased clinker factor of 75%. However, specific emissions for NO_x, SO₂ and mercury all rose slightly from 2014.

“The numbers show what kind of progress HeidelbergCement made in 2015,” said Bernd Scheifele, CEO of HeidelbergCement. “We have also substantially intensified our commitment to the development of technologies to use CO₂ as a resource, and we have entered into very promising cooperative research projects. This puts us at the forefront of the movement in the cement industry.”

The 2015 report is also the first to present data on water management, following the implementation of industry indicators for water reporting at all cement plants in 2013 and 2014.

Taiwan: Taiwan Cement plans to expand its microalgae unit to boost astaxanthin production from waste CO₂. The cement producer intends to invest US$6.25m towards enlarging its existing microalgae unit into a 20-hectare outdoor microalgae farm with an estimated annual production value of about US$12m, according to the Tapei Times.

The upgraded farm will start operation in 2017 producing astaxanthin, an input for skincare and health food products. The company hopes to make astaxanthin products that meet universal standards, such as the Good Manufacturing Practice standard, eventually becoming the country’s main supplier of the chemical.

To support the upgrade Taiwan Cement has signed a business development contract with the Industrial Technology Research Institute (ITRI). The two organisations have collaborated since 2011 on developing CO₂ capture technology. As part of the new deal Taiwan Cement is expected to decrease its CO₂ emissions by 4800t/yr.

Canada: The Cement Association of Canada has become a member of the Carbon Pricing Leadership Coalition (CPLC) as a strategic partner. The CPLC is a voluntary initiative that supports and encourages the implementation of carbon pricing around the world. It was initiated by the World Bank at the 2014 United Nations Climate Change Summit in New York City and officially launched in 2015 at COP21 in Paris.

“Well designed carbon pricing systems can drive innovation and prepare companies and communities to prosper in a competitive, low carbon and climate resilient economy,” said Michael McSweeney, President and CEO, Cement Association of Canada. “We have long advocated for carbon pricing in Canada and globally and are eager to continue our work with the federal and provincial governments to help them design and implement climate policies that support the goals of the Paris Agreement, protect and enhance the competitiveness of the domestic industry and promote alignment on carbon pricing among our trading partners.”
