Materials and products used in building, such as steel and aluminum, are created by a production process of raw material extraction, raw material process, melting, manufacture to final products, and transportation to building sites. Each of the steps consumes energy, which is also expressed in terms of carbon emissions. Total carbon emissions of all building materials and products and the construction involved to put them together is known as building’s embodied carbon. Embodied carbon accounts for about 20% of the carbon emissions from the building sector (Lane, 2010).

This report explores how Britain can achieve Carbon neutrality. Building upon the groundwork laid by the Zero Carbon Britain project over the last six years, the authors incorporate the latest developments in science and technology, plus more detailed research in two main areas: balancing highly variable energy supply and demand; and the nutritional implications of a low carbon diet. The report highlights the need for further research on adaptation, economic transition and policy that would achieve sufficient greenhouse gas emissions reductions quickly and equitably.

In Malawi, increasing demand for housing has put tremendous pressure on the building material sector, resulting in deforestation, rising costs and poor quality construction.
Malawi holds potential for the adoption of green building materials. Mozambique, Kenya, Ethiopia, Zambia and Tanzania have expressed interest in clean construction technology transfer.

Technology
Background: Epoxies are thermosetting polymers formed through the combination of a resin and a hardener. They are extensively used for coatings for adhesives and as a base for composite materials. Epoxies are recognized for their versatility high tensile strength and high temperature resistance. However due to environmental and health concerns there is a growing demand for epoxies that are safer for both the user and environment. Description: Michigan State University’s technology is the formulation of an eco-friendly epoxy.
