Intergenerational equity can help to prevent climate change and extinction

An Author Correction to this article was published on 28 March 2018

This article has been updated

Intergenerational rights to a healthy environment are protected by the constitutions of 74% of the world’s nations. These explicit commitments and similar, ancient principles of sovereign public trust are often overlooked but, if enforced, they offer sustainable protection for the biosphere.

Change history

  • 28 March 2018

    The original Article mistakenly coded the constitutional rights of Australia as containing a governmental duty to protect the environment (blue in the figures); this has been corrected to containing no explicit mention of environmental protection (orange in the figures). The original Article also neglected to code the constitutional rights of the Cayman Islands (no data; yellow in the figures); this has been corrected to containing a governmental duty to protect the environment (blue in the figures).

    Although no inferences changed as a result of these errors, many values changed slightly and have been corrected. The proportion of the world’s nations having constitutional rights to a healthy environment changed from 75% to 74%. The proportions of nations in different categories given in the Fig. 1 caption all changed except purple countries (3.1%): green countries changed from 47.2% to 46.9%; blue countries changed from 24.4% to 24.2%; and orange countries changed from 25.3% to 25.8%. The proportion of the global atmospheric CO2 emitted by the 144 nations changed from 72.6% to 74.4%; the proportion of the world’s population represented by the 144 nations changed from 84.9% to 85%. The values of annual average CO2 emissions for blue countries changed from 363,000 Gg to 353,000 Gg and for orange countries from 195,000 Gg to 201,000 Gg. The proportion of threatened mammals endemic to a single country represented by the 144 countries changed from 91% to 84%. Figures 1–3 have been updated to show the correct values and map colours and the Supplementary Information has been updated to give the correct country codes.
