Climate change is the major, overriding global issue of our time and the single greatest challenge we face. It is a growing crisis with not only environmental concerns but economic, health and safety, food production, security and, of course, trade dimensions. However, a proactive approach to addressing climate change can also open opportunities in new markets and create new business prospects in developing countries. As many businesses are discovering, environmentally sustainable trade is good both for the planet and for business, too. In this online edition of Trade Forum we explore the challenges posed by climate change and the business opportunities that exist for entrepreneurial vision and innovation in tackling them. The success stories of businesses that implement renewable energy practices and new technologies and reduce CO2 emissions, while creating jobs and realizing cost-savings, offer inspiration for us all.
