Guidelines from the contest Advisor(s) and Fellow(s) #
The cement industry is one of the most carbon-intensive industries, due in large part to the thermal energy required to produce clinker, the key component of Ordinary Portland Cement (OPC), the industry standard. The world produced 3 billion metric tons of cement in 2009, emitting more than 2.4 gigatons (Gt) of CO2 into the atmosphere. The industry predicts global cement production is projected to grow to 5.9 billion tons by 2020, amounting to annual CO2 emissions from the production of cement to more than 4.8 Gt. China alone is expected to produce an extra 4 billion metric tons of cement annually by 2020.
Aggressive pursuit of proven carbon intensity reduction measures has the potential to reduce emissions from cement production by 0.9 Gt annually by 2020.The largest potential source of reductions with proven technology is the accelerated use of alternative fuel (370 Megatons or Mt), followed by clinker substitution with alternative materials (300 Mt), thermal energy efficiency improvements (140 Mt), and electricity efficiency improvements (90 Mt). The development of nanotechnologies and other OPC alternatives also shows tremendous potential for reducing emissions in the industry while generating billions in additional economic activity.
Due to high capital expenditure requirements, most cement plants are highly leveraged. As a result, cement manufacturers encounter difficulties accessing capital for investment in efficiency improvements to reduce emissions.
Globally, 18 major cement producers--including the top five cement producing companies--together account for a mere 30 percent of total cement production. Cement producers are in a competitive market dominated by price and therefore they cannot compromise on quality. As a result, the industry is risk averse and reluctant to invest in unproven technology.
Two important levers for decreasing emissions are:
- reducing the clinker content of cement, and
- finding alternative ways of producing clinker.
Each measure, however, has an impact on one or more of the desired characteristics of cement such as strength, durability, malleability, and price. As a result, these cements often fail to comply with various regulations and procurement standards, many of which require reform. Alternative cements therefore end up being used in most cases for niche applications, though certain types of blended cements are being used as direct replacements for OPC.
Key issues #
Contest Focus This contest asks what can be done to reduce GHG emissions in the cement industry profitably.
Possible Actions The goal of this contest is to propose solutions with the potential for catalytic impact. This is defined as any strategy or approach that can result in the creation of conditions that will allow for the deployment of clean-tech process changes that are demonstrably profitable under current policy, on a scale that can result in an annual, gigaton-scale (billion tons) abatement of CO2 emissions.
- Innovative financing mechanisms for cement plant retrofits
- Strategies for increasing the use of biomass for firing cement plants
- Solving for informational deficiencies
Geographic Focus The scope of this contest is the entire world. While the majority of cement production occurs in China, and China's percentage of market share is rapidly rising, many of the technologies that can greatly reduce emissions in this industry are being developed in the United States, Europe, and by entrepreneurs and researchers throughout the world.
Key Actors Proposals can include actions to be taken by a wide range of actors, including, for instance:
- Major cement companies, cement plant operators, and others within the industry
- Technology providers and members of the scientific and technical community
- Key industry players in the building sector, such as engineering, design, and construction firms
- Financial institutions and insurers
- Government organizations, in particular, state/provincial and local government agencies (though proposals are limited to actions within current regulatory and legislative frameworks)
- Non-profit & non-governmental organizations
Judges and contest-specific prizes #
Judges for this contest will include:
- Philippe Fonta, Managing Director Cement (CSI), Buildings (EEB) and Tires (TIP) projects), World Business Council for Sustainable Development
- Hamlin Jennings, Executive Director, Concrete Sustainability Hub, MIT
- David Lange, University of Illinois
- Dr Moray Newlands, Lecturer in Civil Engineering, University of Dundee
- Cecilia Tam, Senior Energy Analyst, International Energy Agency
Cecilia Tam is a Head of the Energy Demand Technology Unit at the International Energy Agency (IEA), where she also leads the IEA's Energy Technology Roadmaps Program. She joined the IEA in 2006, and her work there has covered technology roadmaps, finance, technology deployment, analysis of heavy industry, and energy efficiency indicators. Ms. Tam has authored numerous IEA publications including the IEA's flagship publication Energy Technology Perspectives. Prior to joining the IEA, Cecilia was a Senior Equity Research Analyst with Dresdner Kleinwort Benson where she covered Latin American electricity companies, working on numerous privatizations and equity offerings.
The prize will be an all expenses-paid trip to a Carbon War Room Creating Climate Wealth Summit, date to be determined. At this event, the winner will have the opportunity to present their proposal to an audience of motivated executives, investors, entrepreneurs and other leaders from both the private and public sectors.
All teams that prepare winning proposals will be invited to present their work at in person or virtually at an event at MIT to be held in the 2013, where all the winners from 2012-13 Climate CoLab contests will be featured. The Climate CoLab staff plan to invite a range of policymakers, business executives and investors and NGO officials to this MIT event.
