Carbon footprint man-made infrastructures resulted in a net loss to the atmosphere, -0.6 Mg C ha y. Carbon dioxide emissions into the atmosphere, and the emissions of other GHGs, are often associated with the burning of fossil fuels, like natural gas, crude oil and coal. While this is harmful to the environment, carbon offsets can be purchased in an attempt to make up for these harmful effects. The Kyoto Protocol defines legally binding targets and timetables for cutting the GHG emissions of industrialized countries that ratified the Kyoto Protocol. Accordingly, from an economic or market perspective, one has to distinguish between a
History of the petroleum industry in Canada (natural gas) Calgary in 86 days. It augmented the Dingman enterprise in Calgary, which was unable to supply the growing demands of the city. By 1913, several other towns in southern Alberta boasted natural gas service from the Canadian Western system. Coste's pioneering enterprise provided fuel to nearly 7,000 customers. Sour gas, as it is known, in its natural state is laced with hydrogen sulfide (HS), which can be lethal if inhaled in even tiny concentrations. (The more general term acid gas refers to natural gas with any acidic gas in it - carbon dioxide (CO), for example.) The process of taking
