Singapore's power grid uses primarily natural gas [1], at 0.5 g CO2/Wh [2].
Coal is about 0.9 g CO2/Wh [3].
One of the links in the article is to http://www.climatecentral.org/news/a-roadmap-to-climate-friendly-cars-2013-16318 http://www.climatecentral.org/news/a-roadmap-to-climate-frie... , which shows the places in the US where it's better to have a hybrid than an electric vehicle, if your primary concern is CO2 emissions. These include West Virginia, where 95.5% of the electricity comes from coal. [8]
I've been looking for a country where there are only coal powered power plants. The developed countries countries which use the most coal as a percentage of electricity generation include Australia and Greece [4], at about 75% [4,5]. China is also at 75% [6], while it's 61% in India [7].
There are, it therefore seems, very few places where an electric car is not significantly better than a (non-hybrid) gasoline vehicle with respect to CO2 emissions.
