Impact of climate change by 2030 - indian perspective

Abstract

This paper aims to establish the effect of Green House Gases (GHGs) emissions on climate change. Greenhouse gas molecules formed due to anthropogenic activities absorb infrared radiations from the sun, and these molecules re-emit the radiations in all directions, causing temperature rise of the Earth's surface. Due to anthropogenic activities in the country, GHG emissions of GHGs are increasing. The motor vehicles running in the Indian cities with the fossil fuels like gasoline, diesel, etc., are emitting Carbon-di-oxide (CO2), Hydrocarbon (HCs), Nitrogen oxides (NOx) and water vapor as greenhouse gases in the form of vehicular exhausts. These emissions are responsible for deteriorating ambient air quality of the cities like Delhi, National Capital Region (NCR), Mumbai, Kolkata, Bangalore, Hyderabad, etc. This paper outlines the necessary technologies and practices to mitigate GHG emissions of GHGs. The paper also discusses some of the strategies for reducing emissions of GHGs to minimize the effect of global warming and climate change. The impacts of implementing energy efficiency and conservation measures, the role of renewable energy, and hydrogen blends in the vehicular fuel Compressed Natural Gas (CNG) are also described in this paper. The emission performance of a passenger car suitable for bi-fuel combustion with 18 Hydrogen Compressed Natural Gas (18HCNG) has been compared with neat CNG fuel. The economic analysis with these two vehicular fuels in respect of reducing CO2 and NOx being greenhouse gases, has also been discussed in this paper.
