Synopsis The burning of fossil fuels for energy has resulted in erratic weather conditions, known as the greenhouse effect. While the world is yet to find other cheap sources of energy, burning of fossil fuels is inevitable. The fast depletion of fossil fuels is resulting in sky rocketing prices. While man cannot control the weather, he has come out with an innovative way of ensuring that related trades and industries do not get affected if it becomes erratic. This is done through weather derivatives, an innovative instrument that protects the buyers, in case they incur a loss in return for a nominal premium. Similarly, energy derivatives have been introduced, in order to ensure that buyers of fuel and refiners of crude are not affected by the ever rising prices of fossil fuels. A very interesting development has been the Kyoto protocol on emissions of harmful gases into the atmosphere. Under this protocol, the world has been divided into developed and developing nations, whereby, the former have been given a limit of emissions as an obligation to adhere to. As a result, developed nations have to buy emission credits mostly from developing nations that do not emit as much gas as they are allowed, or in other words, environmental derivatives. Weather, environmental and energy derivatives, have given a formidable opportunity to hedge funds to make clean profits by trading into these instruments. While the concept is still new, more and more funds are entering the market as they result in clear cut profits.
