Low Carbon Resilient Delhi Megacity for Sustainable Future Earth

Abstract

The low carbon economy has a minimal output of greenhouse gas emissions into the biosphere, specially refers to carbon dioxide. Urbanization is one of the significant drivers for rising CO₂ emissions. In India, Delhi appears to be a good geographical location for a study of low carbon society because it represents a large urban area where emissions have reached significant levels and are continuing to grow rapidly. This paper aims to prepare a CO₂ emission inventory for Delhi and identifying major sources and sectoral contributions. The primary and secondary survey was carried out to fulfill the objectives of the study. Based on the certain factors, emissions from transport, residential, industrial, and transport sector were calculated. The solar use feasibility index for Delhi was been prepared based on index overlay method. Simulation of proposed solar water heating systems has been done using RET screen International Computer Software. The problem of CO₂ emission is even seen prominently within Indian mega cities. Among various mega cities, Delhi is the most affluent city as it supports a population of 16.75 million. Transport is the leading producer of CO₂ in Delhi, followed by residential, commercial and industrial sector. Being a national capital, Delhi continues to attract the population and to cope with that the residential and industrial development has to take place. So, it is important that the prime attention should be given to make the city environmentally sustainable (use of renewable sources of energy).
