Carbon Neutrality of Cement Plant

Among the foremost environmental challenges that the world is facing today are the issues of global warming and climate change. Emission of greenhouse gases is a major contributor to these issues. To minimize energy consumption and thereby reduce emissions of greenhouse gases, it is very important to ensure source identification for achieving the goal towards sustainable development. Carbon footprint measurement is an effective tool used to calculate the greenhouse gas emissions and its effect on the environment. Objective: This study aims to assess the carbon footprint generated by various emission sources and suggest suitable methods for reducing it. Methodology: Greenhouse gas emissions for an entity in terms of tones of equivalent CO2 generated per year is reported using three basic steps including accounting the data, calculation and estimation of CO2 emitted. The carbon footprint is estimated by accounting direct emission from sources owned / controlled by the entity (scope 1), from indirect emission including essential activities (scope 2) and other outsourced distributions (scope 3). These emissions are converted to CO2 equivalent values taking into account their respective emission factors. Finally, the total CO2 emissions for an entity will be estimated. Direct emissions: Activities of the entity that release emissions straight into the atmosphere. They are direct emissions. Examples of scope 1 emissions include emissions from combustion in furnaces, vehicles etc. Energy indirect: Emissions being released into the atmosphere associated with our consumption of purchased electricity, heating and cooling. These are indirect emissions that are a consequence of activities, but which occur at sources outside the entity. Other indirect: Emissions that are a consequence of our actions, which occur at sources which we do not control, and which are not scope 2 emissions. Examples of scope 3 emissions are travel by means that are not owned, waste disposal, or purchased materials or fuels.
