The preliminary determination of the article is to investigate the effects of pollution and climate change. In this regard, the authors want to highlight that this real and critical issue must take seriously because each of us contributes to pollution and climate change, which is very real, and which will be aggravated by not taking action. Global warming currently involves two major problems for humanity: on the one hand, the need to dramatically diminish greenhouse gas emissions to stabilize the concentration of these gases in the atmosphere to prevent anthropogenic influence on the climate system and enable ecosystems, contrastingly the need to accommodate to the consequence of climate change, given that these effects are already visible and inevitable due to the activity of the climate system, regardless of the outcome of emission reduction actions. The main problem with pollution is air quality, which has fallen considerably, especially in urban areas. The" World Health Organization" approximates, more than seven million people die each year from air pollution. The authors also conducted a case study on the local effects of climate change - Timisoara and its peri-urban area. Therefore, we concluded that if Timisoara is successful in reducing greenhouse gas emissions, this will create a test market for Romania's ecological technologies and help the environmental industries to locate in Timisoara.
