Keen to cement its position as one of the world's greenest multinationals, Toyota has announced it is to fund a major research project designed to identify the most energy efficient best practices that firms should be embracing.

The company said that it will provide a three year $1.4m grant to the Pew Center on Global Climate Change in Washington to fund the research project.

The Center said it was now seeking to collect data direct from leading US firms as it looks to compile a list of the most effective energy efficiency policies from across companies' supply chains, facilities, products and services.
