Climate change is an issue that none of us can afford to ignore; the way that firms respond to environmental issues will be critical to their future success. Buyers of professional services are now actively considering a firm’s climate credentials when making purchasing decisions, and firms are asking themselves what they can do to demonstrate their commitment to the planet. Evolving attitudes towards these issues also create opportunities for the firms willing to take advantage of them. While the transition to a low-carbon economy will not be an easy one, it is clear that professional services firms have an absolutely critical role to play in making it happen.
