Oxfam warns the richest 1% exhausted their annual carbon share in days, while poorer nations face rising climate losses, prompting calls for wealth taxes and urgent action from governments worldwide.
The world’s richest 1 percent exhausted their fair share of annual carbon emissions just 10 days into 2026, while the wealthiest 0.1 percent used up their entire yearly carbon budget in only three days, according to a new analysis by humanitarian aid organization Oxfam.
The charity warned that the climate damage caused by these excessive emissions is disproportionately borne by those least responsible for the crisis, particularly people in low- and middle-income countries, Indigenous communities and women and girls living on the frontlines of climate breakdown.
Oxfam’s analysis shows that lower- and middle-income nations are most exposed to the harmful effects of rising emissions, with global economic losses from climate impacts potentially reaching £44 trillion by 2050 if current trends continue.
Calling for urgent policy action, Oxfam urged the UK chancellor to increase taxes on climate-polluting extreme wealth. The organisation said the UK’s richest 1 percent alone produced more carbon pollution in just eight days than the poorest half of the population generated in an entire year.
The report also highlights that the super-rich are not only responsible for disproportionate personal emissions but are major investors in highly polluting industries. On average, a billionaire’s investment portfolio is linked to the production of about 1.9 million tonnes of carbon dioxide annually, roughly equivalent to the emissions from 400,000 petrol-driven cars.
To remain within the Paris Agreement target of limiting global temperature rise to 1.5 degrees Celsius above pre-industrial levels, Oxfam said the richest 1 percent of the global population would need to cut their emissions by 97 percent by 2030.
Beth John, climate justice adviser at Oxfam GB, said governments must focus on the biggest polluters to curb climate damage. She said repeated chances to make the wealthiest pay their fair share for climate action have been missed in the UK but significant opportunities remain.
Sohanur Rahman, Executive Coordinator of YouthNet Global, stressed the global responsibility of the wealthy, saying, “Those with the most resources and power must lead the fight against climate change. It is unacceptable that the richest contribute disproportionately to emissions while the poorest face the harshest impacts. Fair taxation and accountability are key to a sustainable future.”
He added that engaging young people worldwide in climate advocacy is essential to ensure a just transition and a safer planet for all.
