Cement technology roadmap plots path to cutting CO2 emissions 24% by 2050

Published

on

Paris and Geneva – A combination of technology and policy solutions could provide a pathway to reducing direct carbon dioxide emissions from the cement industry by 24% below current levels by 2050, according to a new report by the International Energy Agency (IEA) and the Cement Sustainability Initiative (CSI).

The technology roadmap, called Low-Carbon Transition in the Cement Industry, 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 cement sector is the third-largest industrial energy consumer in the world, responsible for 7% of industrial energy use, and the second industrial emitter of carbon dioxide, with about 7% of global emissions. Cement is the key ingredient of concrete – which is used to build homes, schools, hospitals and infrastructure, all of which are important for quality of life, social and economic wellbeing.

As global population rises and urbanization grows, global cement production is set to increase between 12 to 23% by 2050.

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. Realising the IEA’s more ambitious 2°C Scenario (2DS) by 2050, which seeks to limit average global temperature increases to 2°C, implies significantly greater efforts to reduce emissions from cement makers.

The low-carbon transition of the cement industry can only be reached with a supportive regulatory framework as well as effective and sustained investments. Meeting the RTS already requires additional cumulative investments compared to the status quo. Achieving the transformation described by the 2DS could mean up to a doubling of these investments compared to the RTS. 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.

As a flagship sectoral project of the World Business Council for Sustainable Development (WBCSD), the CSI is a global effort currently gathering 24 major cement producers having operations in more than 100 countries and who have integrated sustainable development into their business strategies and operations.

“The cement industry is a major part of the global economy, but also an important source of global energy demand and carbon emissions. It is therefore essential that policy-makers and industry work together to ensure best-practices are adopted that put the industry on a long-term sustainable path that is compatible with our long-term climate goals,” said Dr. Fatih Birol, the IEA’s Executive Director.

Mr. Philippe Fonta, Managing Director, CSI of WBCSD added, “The CSI is happy and proud to have developed this roadmap update in partnership with the IEA. 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).”

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 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. This can include optimising the use of concrete in construction by maximising design life of buildings and infrastructures, encouraging reuse and recycling, reducing waste and benefiting from concrete’s properties to minimise energy needs for heating and cooling of buildings.

The roadmap outlines policy priorities and regulatory recommendations, discusses investment stimulating mechanisms and describes technical challenges with regard to research, development and demonstration.

Technologies That Are The Future

Published

on

Innovation is the introduction of something new. As we are in this progressing age, one can observe changes in the surroundings within seconds. To cater for this, technological advancements and new innovations with better features are the need of the hour. Futurists of the 1950s or so predicted that by 2000s, we will have flying cars and airborne robots. While the forecasters had their timing wrong, but their foresighted technology was right. Today we are at the brink of manufacturing self-driving cars and robot assistants.

Among these, another important innovation that will go mainstream is the ‘Voice Assistants’. In about four to five years, every home is expected to have a voice assistant like Amazon Echo or Apple Homepod. This is all thanks to the power of artificial intelligence that we are able to develop something like this. Voice assistants are making a vital change in markets all around the world and some scientists believe that in the near future, people will be communicating through voice rather than text. This will save time which can be used in completing other tasks.

Another emerging technology is the technique of ‘Reversing Paralysis’. Researchers have begun using brain-reading technology which helps the people with paralysis to move their limbs again. This is done by placing an electronic implant in the brain which is connected to electrical stimulators located on the body to create a ‘neural bypass’. Although the progress in implementing this technology is slow but this technology is also being tested for people with other diseases like arthritis. These innovations with new advances would allow patients to regain control of their bodies.

The wait for ‘Quantum Computers’ is ending soon. A computer that can accelerate pharmaceutical research, compute equations that are hard to fathom right now or rewrite encryptions. Quantum computers have more qubits, the basic unit of quantum information. Qubits need ideal conditions to function properly, but new technology reduces the computational capability needed to correct errors caused by physical intrusions. These computers will be in the commercial market for common use by anyone in a few years.

The next on list are the ‘Hot Solar Cells’. Solar panels are more efficient today than their previous versions, but they still absorb only a fraction of sunlight. To solve this problem, hot solar cells are introduced which convert the sunlight into heat and then back to light. So, what happens is an ‘absorber-emitter’ absorbs the sunlight then converts it to heat and funnels it to solar cells. This system could even allow energy to be stored for later use. This system could deliver continuous power even when the sun is not shining.

‘Botnets’ is the real game changer in the list. As we are living in the age of smart phones, laptops, internet, media, etc. we do not entirely realize the importance of cyberattacks. Botnets are centralized systems that gain control of internet connected devices to launch cyberattacks. The situation is getting worse day by day with so many devices that have little to no cybersecurity measures. Botnets can evade spam filters, create click fraud, and launch denial-of-service attacks. Once a botnet is spotted, its command and control center can be attacked and rendered ineffective. In the coming years, botnet trends favor the attacker, and more botnet attacks will be coming for internet users.

A world where genetic diseases like Huntington’s and cystic fibrosis are defeated is something, we all wish for. Well, thanks to ‘Crispr’, genetic diseases may be eliminated. CRISPR Cas-9 is an abbreviation for ‘Clustered Regularly Interspaced Short Palindromic Repeats’. It is a gene-splicing technology which is capable of finding and removing mutated sections of DNA. Once it is removed, crispr can replace the mutated ones with non-mutated variants. In conclusion, crispr has the ability to permanently remove certain types of genetic diseases from blood lines. It is already being used to eliminate cancer cells in some patients and may as well be able to cure genetically caused blindness as well in the near future.

Practice makes a man perfect but you never know the advancements in the technology might make the robots perfect too. ‘Reinforcement Learning’ is a new technique which helps artificial intelligence (AI) to solve problems it has never seen before. This concepts is connected with a large neural network which is trained to recognize patterns in data. The computer learns which information is correct and which is not and continuously improves itself. A computer using this technology can beat one of the best players in the world. Reinforcement learning might be moving towards its most vital tests soon with its use in self-driving cars and other technologies.

Another new technology in the market is the ‘Gene Therapy’. It is for hereditary diseases and is available in Europe market and will soon be launched in the United States. The success of these gene therapies increased phenomenally when scientists started to use viruses that are more efficient at transporting new genetic materials. Gene therapies can even treat the diseases which involve multiple genes. This kind of treatment might seem rare now but will be more common in the blink of an eye.

At one point last year, Bitcoin was worth more than $19,000 per coin but recently the value of cryptocurrency has decreased still a single coin is worth thousands of dollars. Cryptocurrency has stirred up controversy around the world but it is steadily becoming mainstream. Platforms like TrustToken and HybridBlock are poised to connect the global trading power of blockchains with real world assetd and are designed to give crypto enthusiasts greater access to silo trading markets which help to expand the industry to a new wave of crypto enthusiasts. As a result, sellers can make illiquid assets liquid, and buyers can have control of a vast portfolio of assets. By giving access to mobile friendly products like easy to use applications, these platforms are providing the market with a new form of crypto education and the tools to execute crypto trades.

Last but not the least on the list is the ‘Artificial Intelligence and Automation’. Some of the world’s most famous brands are majorly turning to automation in order to serve their customers better and become more affordable by reducing the costs. Big box retailers utilize automated warehouses to sort and ship products, while social media networks use automation to moderate comments and credit card companies use automation to detect fraud and theft. The implications here are massive because a new artificial intelligence economy incorporating the decentralized blockchain AI, can change the way businesses operate and run around the world.

Indeed, it is just a matter of time before everything goes to the market. We are moving to a time where everything is just a click away. New innovations are coming daily, changes are being made within minutes. In fact, as we speak, we might be unaware but there might be some company in the world working at this hour to bring a change to your smartphone but there is nothing we can do about it. We just have to hang in there and go with the flow.

What is a ‘vaccine passport’ and will you need one the next time you travel?

Published

Is the idea of a vaccine passport entirely new?

The concept of a passport to allow for cross border travel is something that we’ve been working on with the Common Trust Network for many months. The focus has been first on diagnostics. That’s where we worked with an organization called “The Commons Project” to develop the “Common Trust Framework”. This is a set of registries of trusted data sources, a registry of labs accredited to run tests and a registry of up-to-date border crossing regulations.

The set of registries can be used to generate certificates of compliance to prevailing border-crossing regulations as defined by governments. There are different tools to generate the certificates, and the diversity of their authentication solutions and the way they protect data privacy is quite remarkable.

We at the Forum have no preference when it comes to who is running the certification algorithm, we simply want to promote a unique set of registries to avoid unnecessary replication efforts. This is where we support the Common Trust Framework. For instance, the Common Pass is one authentication solution – but there are others, for example developed by Abbott, AOK, SICPA (Certus), IBM and others.

How does the system work and how could it be applied to vaccines?

The Common Trust Network, supported by the Forum, is combining the set of registries that are going to enrol all participating labs. Separately from that, it provides an up-to-date database of all prevailing border entry rules (which fluctuate and differ from country to country).

Combining these two datasets provides a QR code that border entry authorities can trust. It doesn’t reveal any personal health data – it tells you about compliance of results versus border entry requirements for a particular country. So, if your border control rules say that you need to take a test of a certain nature within 72 hours prior to arrival, the tool will confirm whether the traveller has taken that corresponding test in a trusted laboratory, and the test was indeed performed less than three days prior to landing.

The purpose is to create a common good that many authentication providers can use and to provide anyone, in a very agnostic fashion, with access to those registries.

What is the WHO’s role?

There is currently an effort at the WHO to create standards that would process data on the types of vaccinations, how these are channelled into health and healthcare systems registries, the use cases – beyond the management of vaccination campaigns – include border control but also possibly in the future access to stadia or large events. By establishing in a truly ethical fashion harmonized standards, we can avoid a scenario whereby you create two classes of citizens – those who have been vaccinated and those who have not.

So rather than building a set of rules that would be left to the interpretation of member states or private-sector operators like cruises, airlines or conveners of gatherings, we support the WHO’s effort to create a standard for member states for requesting vaccinations and how it would permit the various kinds of use cases.

It is important that we rely on the normative body (the WHO) to create the vaccine credential requirements. The Forum is involved in the WHO taskforce to reflect on those standards and think about how they would be used. The WHO’s goal is to deploy standards and recommendations by mid-March 2021, and the hope is that they will be more harmonized between member states than they have been to date in the field of diagnostics.

What about the private sector and separate initiatives?

When registry frameworks are being developed for authentication tools providers, they should at a minimum feed as experiments into the standardization efforts being driven by WHO, knowing that the final guidance from the only normative body with an official UN mandate may in turn force those providers to revise their own frameworks. We certainly support this type of interaction, as public- and private-sector collaboration is key to overcoming the global challenge posed by COVID-19.

What more needs to be done to ensure equitable distribution of vaccines?

As the WHO has warned, vaccine nationalism – or a hoarding and “me-first” approach to vaccine deployment – risks leaving “the world’s poorest and most vulnerable at risk.”

COVAX, supported by the World Economic Forum, is coordinated by the World Health Organization in partnership with GAVI, the Vaccine Alliance; CEPI, the Centre for Epidemics Preparedness Innovations and others. So far, 190 economies have signed up.

The Access to COVID-19 Tools Accelerator (ACT-Accelerator) is another partnership, with universal access and equity at its core, that has been successfully promoting global collaboration to accelerate the development, production and equitable access to COVID-19 tests, treatments and vaccines. The World Economic Forum is a member of the ACT-Accelerator’s Facilitation Council (governing body).
