From BP's website:
As an energy manager with alternate fuel switching capabilities you are concerned about emissions allowances. You're managing either short or long allowances, or you’re challenged by being short today and long next month. What do you do?
SOLUTION: Contact your BP representative for help developing your emissions strategy. Using financial trading tools such as options may provide a viable and effective solution. If you are short allowances, consider purchasing a call option from BP. This will allow you to buy emissions allowances at a known strike price. If you are long allowances, purchase a put option from BP so that you can sell them at a known strike price. Source
