Energy and the environment are two of the most important issues this century. More than 80 % of our energy comes from the combustion of fossil fuels, which will still remain the dominant energy source for years to come. It is agreed that carbon dioxide produced from the combustion process to be the most important anthropogenic greenhouse gas leading to global warming. Atmospheric CO

concentrations have indeed increased by almost 100 ppm since their pre‐industrial level, reaching 384 ppm in 2007 with a total annual emission of over 35 Gt. Prompt global action to resolve the CO

crisis is therefore needed. To pursue such an action, we are urged to save energy without the unnecessary production of carbon emissions and to use energy in more efficient ways, but alternative methods to mitigate the greenhouse gas have to be considered. This Minireview highlights some recent promising research activities and their prospects in the areas of carbon capture and storage and chemical fixation of CO

in constructing a future low‐carbon global economy with reference to energy source, thermodynamic considerations, net carbon emissions and availability of reagents.
