The Paris Climate Change Conference failed Humanity and has locked in a catastrophic temperature rise of about plus 2.7 degrees C. All ordinary folk can do is to boycott the worst polluters. World Bank analysts have revised annual greenhouse gas (GHG) pollutions upwards by 50% to 64 billion tonnes CO2-e by properly accounting for land use for animal husbandry and the same approach has been used here to properly re-calculate annual per capita GHG pollution for all countries and hence the best targets for global Boycotts, Divestment and Sanctions (BDS) to save the planet.
World Bank analysts carefully re-evaluated the contribution of livestock production to world annual GHG pollution and found that the world’s annual total rose from 41.76 billion tonnes CO2-equivalent (CO2-e) as estimated by the Food and Agricultural Organisation (FAO) to 63.80 billion tonnes CO2-e, with livestock production contributing over 51% of the higher figure [1]. A key element of their analysis was to use a Global Warming Potential (GWP) of methane (CH4) relative to that of carbon dioxide (CO2) of 72 in a 20-year time frame rather than the 25 on a 100 year time frame used by the FAO [1]. Indeed the World Bank analysis evidently still understates the GHG pollution because NASA scientists have re-evaluated the GWP of CH4 as 105 in a 20 year time frame with aerosol impacts considered [2].
