Over the past 140 years the earth's surface temperature has increased on average by 0.6C with the greatest increases occurring during the second half of the last century. With temperatures expected to increase by between 1.4C and 4C over the next century we all have to take responsibility for our actions. Public awareness of climate change is growing and consumers are becoming increasingly driven by the environmental awareness displayed by the products and services they use. By demonstrating that you are socially responsible as a company not only can you have a real impact on the environment but also take the opportunity to differentiate yourself from the competitors in your market. Environmental awareness provides additional reasons for your clients to continue using your services over those of your competitors. It also presents valuable marketing and PR opportunities for your business in a highly competitive market.
