One of the biggest barriers to companies making their operations green is coming up with the initial capital. Despite proof that going green pays off through lower costs, few companies, especially in these tight times, feel they can make the necessary investment. Instead of searching for that lump sum, try a set-aside.

Put aside a small percentage of your existing capital budget – even as low as 1% has worked for some companies – and earmark it for green priorities. By dedicating even a small amount to green projects, you will begin to see savings and make an investment in your company's future.
