text: An increasing commitment by the UNEP (and national governments such as the UK) to the ideas of natural capital and full cost accounting under the banner 'green economy' could blur distinctions between the schools and redefine them all as variations of "green economics".  As of 2010 the Bretton Woods institutions (notably the World Bank and International Monetary Fund (via its "Green Fund" initiative) responsible for global monetary policy have stated a clear intention to move towards biodiversity valuation and a more official and universal biodiversity finance.
  The UNEP 2011 Green Economy Report informs that "based on existing studies, the annual financing demand to green the global economy was estimated to be in the range US$1.05 to US$2.59 trillion. To place this demand in perspective, it is about one-tenth of total global investment per year, as measured by global Gross Capital Formation."
  At COP26, the European Investment Bank announced a set of just transition common principles agreed upon with multilateral development banks, which also align with the Paris Agreement. The principles refer to focusing financing on the transition to net zero carbon economies, while keeping socioeconomic effects in mind, along with policy engagement and plans for inclusion and gender equality, all aiming to deliver long-term economic transformation.
  The African Development Bank, Asian Development Bank, Islamic Development Bank, Council of Europe Development Bank, Asian Infrastructure Investment Bank, European Bank for Reconstruction and Development, New Development Bank, and Inter-American Development Bank are among the multilateral development banks that have vowed to uphold the principles of climate change mitigation and a Just Transition. The World Bank Group also contributed.
