COP30

This week, as business and government leaders, investors and campaigners gather for New York Climate Week, DeSmog is relaunching its big agriculture series, which will scrutinise the power of food and farming companies. Agriculture used to play second fiddle to energy when it came to global warming, considered as a nice-to-have. But as global heating continues apace, emissions associated with food are rising fast. Nitrous oxide – a planet-heating gas nearly 300 times as potent as CO2 when measured over 100 years – is accumulating in Earth’s atmosphere at unprecedented levels. Levels of methane – another powerful greenhouse gas critical to reducing emissions – have soared since the start of the decade and are showing “no hint of decline”.
