Cuts in emissions are almost always linked to problems with economies. Almost all dips in carbon emissions coincide with economic problems. These dips have always been followed with rapid increases in energy demands, as the dip ends. The current crisis is a fantastic opportunity to start the process of reducing are carbon emissions as a species. Some countries have invested heavily to make this happen other world leaders have been less forward-looking.
Good can come from this current epidemic, and if we are to halt rapid and devastating global warming, we must continue this trend, at this rate for a good number of years. Governments must make sure that efforts to restart economies, does not undo these cuts as a by-product.
