ABSTRACT
Climate change now-a-days is considered as the major threat throughout the world. The average global temperature over the past 100 years has raised up to 0.3-0.6ºC and global warming is the major cause of increasing temperature. Pakistan contributes to almost 0.05% in Green House Gases (GHG) emissions and consider as 7th most vulnerable country to climate change. The present article will focus on renewable energy resources to mitigate CO2 emission in Pakistan and to secure glaciers from melting. Review’s finding showed that the extraction of water for irrigation purpose requires 6 billion kWh of electricity which contributes to 3.8 million metric tons of CO2 each year. Water productivity up to 40% can be enhanced by improved irrigation methods. Wind energy, biomass energy, fluidized coal combustion and integrated coal gasification combined cycle (IGCC) play a very important role in reduction of CO2 which in result reduce the effect of global warming and Climate Change.
