The report makes the business case for private sector adaptation to climate change, including through building the resilience of vulnerable communities in developing countries. It draws on the results of a 2010 survey of corporate signatories to the UN Global Compact and the UNEP Caring for Climate initiative, as well as on existing literature. It indicates that 86% of global businesses surveyed described responding to climate risks or investing in adaptation as a business opportunity, and 83% of companies stated that climate change impacts pose a risk to their products and service. Key recommendations include that businesses integrate climate adaptation into core strategic planning and build a portfolio of climate-resilient goods and services. The study also recommends policy makers: demonstrate policy and finance commitment to adaptation; engage businesses as stakeholders in planning and implementation; stimulate the market for adaptation through financial and risk-reduction incentives; develop policy and regulatory frameworks to guide corporate practices; provide businesses with the information and tools they need to make investments that support climate resilience in vulnerable communities; and consider new forms of public-private partnerships to tackle the most complex.
