Sources of CO2 Emissions









Sources of CO2 Emissions
















The purpose of the report is to investigate the global CO2 trends by sampling five selected areas. Consequently, the paper will establish trends of CO2 concentration levels over the last four decades.


Currently, the climate changes are occurring in a rapid way; they occur on unprecedented scales of decades. The recent climate changes have been attributed to the human’s activity that have profoundly raised the CO2 and Methane level (Houghton, 2009). Regarding the level of CO2, the report will seek to discuss its gradual accumulation in the atmosphere over the past forty years. It will gather and present the evidence of CO2 gradual rise in the globe and highlight its implications for the environment based on the statistics and figures presented by the GMD measurement locations.

Hypothesis/Predicted Outcome

The global CO2 levels have rose at unprecedented level owing to the industrial activities and transportation exhaust emissions.


In terms of methodology, the paper involves obtaining data on the CO2 level of five locations on the earth’s atmosphere from the GMD measurement locations. Through observations of the graphs, CO2 level and trends are established, and appropriate conclusions are drawn to ascertain the hypotheses. Considering the accuracy of the GMD measurement, the methodology translates to an accurate and objective report.


Country Annual CO2 Emission in 1990 in billions of tons Annual CO2 Emission in 2005 in billions of tons
China 2.5 5.8
German 0.9 0.8
Japan 1.0 1.2
USA 4.8 5.8
France 0.3 0.4

Data adopted from UN MDG, 2014


Based on the observations made in and the graphical trends illustrated on the five spots, it is clear that the global CO2 levels are rising at an alarming rate. The global CO2 level is mainly determined by the carbon cycle that is at equilibrium. However, in the last few decades, the industrial revolution saw man burn coal and petroleum products for industrial purposes and transportation. Such activities have seen CO2 level rise at an alarming rate. Consequently, the emissions are disrupting the CO2 natural cycle and causing an imbalance (Houghton, 2009).

Four decades ago, there were approximately 1.8 trillion tons of CO2 in the atmosphere. Today, the level has risen to 2.2 trillion tons (Houghton, 2009). All these additional burdens of CO2 level are as a result of industrialization and modern lifestyle.


To sum it up, CO2 has a greenhouse effect and its continuous entrapment in the atmosphere is causing global warming and consequently climate change. The world needs to address it in a rather fast way to adopt clean sources of energy at home and in the industrial sector (NRDC, 2014).
