195 countries gathered in Paris in 2015 to conclude the legally binding climate agreement to reduce their greenhouse gas emissions. Continuous environment monitoring is a prerequisite for designing policies which can reduce global climate emissions. Only a handful of countries have the capabilities to carry out advanced climate measurements. Commercial Off-the-Shelf (COTS) Technologies can lower the technological and financial barriers for developing countries to monitor climate emissions. The authors made use of environmental COTS technologies along with information and communication technologies (ICT) to assess the impact of pollution control initiatives rolled out by the Delhi government on experimental basis.
