Many businesses have taken action to reduce energy use, improve efficiency and cut direct carbon emissions.
They have devised and implemented energy and carbon management strategies, reaping benefits through cost savings and more engaged workforces.
Businesses can reach the next stage by focusing on the indirect carbon emissions from their supply chains and meeting consumers' increased demands for low-carbon products and services.
By studying their supply chains, businesses can map out carbon emitted at every stage of a product's life cycle from source to shelf, consumption and disposal.
Pilot projects with crisps group Walkers and newspapers company Trinity Mirror identified potential annual savings totalling £2.7m and 28,000 tonnes of carbon dioxide - equivalent to the emissions of 5,000 households.
Similar pilot programmes are now under way at confectionery group Cadbury Schweppes, retailer Marks & Spencer and pharmacy chain Boots amongst others.
