Burning fossil fuels, such as coal, oil and gas for energy production is the largest contributor to global climate change, accounting for nearly 90% of all carbon dioxide emissions and over 75% of the global greenhouse gas emissions that are trapping the sun’s heat and warming up the Earth at a faster rate than it has ever been.

A pivot from the world's current reliance on fossil fuel to renewable energy sources to generate energy is key in helping to reduce greenhouse gas (GHG) emissions and make a climate-neutral world. Taking early measures (a change in our energy sources to greener alternatives) will help mitigate the increasing risk that a fast-changing climate inevitably holds.

Not to dwell too much on the risks that a warming earth holds, how are big economies responding to this and what technological solutions are they adopting?
