The Rio Conference in mid 2012 was buzzing about natural capital accounting! Only a very short time ago, we were drawing blank looks when we mentioned “natural capital accounting.” This story (and short film) from the World Bank’s website outlines the success of the 50:50 campaign to get at least 50 countries and 50 companies to move towards adopting natural capital accounting. To support countries with the move to natural capital accounting, the World Bank initiated a partnership called WAVES—Wealth Accounting and the Valuation of Ecosystem Services—which includes several UN agencies, national governments, NGOs, and academic and other institutions. The supporting ideas behind the initiative can be found in the new “Moving Beyond GDP”.
