Open Natural Carbon Removal Accounting
ONCRA stands for Open Natural Carbon Removal Accounting. We are developing this as an open accounting standard and transaction rulebook for natural climate solutions, because it is a systemic missing link. We develop full carbon accounting starting from all Global Goals for Sustainable Development (SDGs) and follow the principles of doughnut economics. Entrepreneurs, innovators, investors, philanthropists, economists, bankers, accountants, hackers and others are invited to join the emerging ecosystem at oncra.org.

Doughnut Economics
Doughnut economics, Kate Raworth’s ideas for an economy that serves human needs within planetary boundaries, is central in our thinking. We create the world’s first dougnut-based natural carbon removal accounting framework, as this will enable the businesscases of thousands and kick-start the new nature economy to beneft both humans and other life. We are a founding member of the Amsterdam Doughnut Coalition.
