Bill Gates has claimed that solving climate change will be far more difficult than ending the Covid-19 pandemic. The billionaire Microsoft co-founder described tackling global warming as 'the most amazing thing humanity has ever done', while calling the pandemic response 'very, very easy' by comparison.
In his new book, 'How to Avoid a Climate Disaster', Gates highlights two key numbers: 51 billion and zero. The first represents the tonnes of greenhouse gases added to the atmosphere annually; the second is the target net emissions needed to halt global warming. He warns that the transition required over the next 30 years has no historical precedent.
Gates argues that while renewable energy can decarbonise electricity, this accounts for less than 30% of emissions. The remaining 70%—from steel, cement, transport, and fertilisers—lacks current viable solutions. He calls for unprecedented innovation and government investment to develop green technologies and create market signals that price in the environmental cost of fossil fuels.
Despite his past opposition to regulation, Gates now advocates for strong government intervention, including research funding and support for new markets. He stresses that political action and consumer choices—such as buying electric cars or plant-based meat—can drive down prices and accelerate the transition. However, he acknowledges that simply consuming less will not solve the problem, as developing nations like India will continue to increase energy demand.
