A new study has revealed that smartphones charging emits greenhouse gases that cause global warming.
According to the study, these gases might even increase from 6.4 megatons to 13 megatons, within five years, CNET reported.
According to the study by analyst Juniper Research, those 13 megatons would be equivalent the current annual emissions of 1.1 million cars and half of those 2019 greenhouse gases would come from mostly used in Asia's coal-fired electricity grids,.
The researchers said that findings may help the smartphone and app makers to become environment-friendly.
