James McHugh Construction appoints new president



A combination of technology and policy solutions could bring a way to reduce direct carbon dioxide emissions (CO 2 ) from the cement industry by 20 percent below the current level by 2050 International Energy Agency (IEA), Paris , and the Cement Sustainability Initiative (CSI), Geneva

The CSI is an important sectoral project of the World Business Council for Sustainable Development (WBCSD), Geneva, and is currently a global initiative 24 major cement producers operating in more than 100 countries integrated sustainable development into their business strategies and processes.

The Technology Roadmap titled "Low Carbon Transition in the Cement Industry" provides an update of the global "Cement" Technology Roadmap, which was created in 2009. The aim of the Technology Roadmap is to identify and promote international collaborative efforts to support EU decision-making Cement industry and policy to move further towards a sustainable cement sector that helps limit global temperature rise to 2 degrees Celsius.

The cement sector is the third largest industrial energy consumer in the world, responsible for 7 percent of industrial energy use, and the second industrial CO 2 emitter, with about 7 percent of global CO 2 emissions, say IEA and CSI

The world's population is rising More people are moving to the cities, and global cement production is expected to increase by 1

2 percent to 23 percent by 2050 grow rozent. By 2050, the direct CO2 emissions of the cement industry worldwide are set to increase by 4 percent within the framework of the IEA Reference Technology Scenario (RTS). The RTS obliges countries to limit emissions and improve energy efficiency. The IEA's 2-degree scenario (2DS) implies an energy system path and CO 2 2 emission trajectory to limit the average global temperature increase to 35.6 degrees Fahrenheit (2 degrees Celsius) by 2050 implies greater efforts to reduce emissions from cement production

The low carbon transition of the cement industry can only be achieved with a supportive regulatory framework and effective and sustainable investment, say IEA and CSI. In order to achieve the transformation defined in the 2DS, these investments would have to be increased. Governments, working in partnership with industry, can play a crucial role in developing political and regulatory mechanisms that unlock the private funding needed to boost investment.

The roadmap is based on a bottom-up approach to identifying potential transitional analysis of the most cost-effective technology for the cement industry to reduce its direct CO 2 emissions in line with the IEA's 2DS. Achieving this goal would require a combination of technology solutions, policy support, public-private collaboration, funding mechanisms and social acceptance, say IEA and CSI.

Improving energy efficiency and switching to alternative fuels coupled with reducing cement clinker content and using emerging and innovative technologies such as carbon capture and the use of alternative binders are the most important methods of reducing carbon in cement production.

Further emission savings can be achieved by considering the entire life cycle of cement, concrete and concrete the built environment. This may include optimizing the use of concrete in construction by maximizing the life of buildings and infrastructures, promoting reuse and recycling, reducing waste, and utilizing the properties of the concrete to minimize energy requirements for heating and cooling buildings [19659002] The roadmap outlines policy priorities and regulatory recommendations, discusses mechanisms for promoting investment and describes technical challenges related to research, development and demonstration.
