Singapore is the first country in Southeast Asia to levy a carbon tax, at $5 per ton, applicable for its largest carbon-emitting corporations that produce more than 25,000 tons of carbon dioxide per year. To reduce the country's dependence on fossil fuels, it is building one of the world's largest floating solar farm at Tengeh Reservoir in Tuas, with a capacity of 60MW.

Geology Igneous rocks are found in Bukit Timah and Woodlands and Pulau Ubin island. Granite makes up the bulk of the igneous rock. Gabbro is also found in the area and is found in an area called Little Guilin named for its resemblance to Guilin in Southern China. This area is in Bukit Gombak. Sedimentary rocks are found on the western part of Singapore and is mainly made of sandstone and mudstones. It also includes the southwestern area. Metamorphic rocks are found in the northeastern part of Singapore and also on Pulau Tekong off the east coast of Singapore. The rocks are mainly made up of quartzite and also make up the Sajahat Formation. Seismic activity Singapore is relatively safe from seismic activity in the region, as the nearest major active faults (Sumatran fault and Sunda megathrust fault) are hundreds of kilometres away in Indonesia. However, the population and buildings are prone to being only very slightly affected by any activity as tremors, which is not uncommon, but generally does not do any harm and is limited to small amounts of swaying or vibration of objects. In late 2004, several parts of Asia and Africa were struck by the 2004 Indian Ocean earthquake and the resulting tsunami.
