Last week, Prime Minister Justin Trudeau announced a plan to reduce plastic pollution, which will include a ban on single-use plastics as early as 2021. This is laudable: plastics clog drains and cause floods, litter nature and kill animals and birds. Of course, plastic also makes our lives better in a myriad of ways. In just four decades, plastic packaging has become ubiquitous because it keeps everything from cereals to juice fresher and reduces transportation losses, while one-use plastics in the medical sector have made syringes, pill bottles and diagnostic equipment safer. Going without...

Chancellor Phillip Hammond was slapped down by Downing Street last week for warning that reaching net zero carbon emissions could cost the UK £1 trillion and require cuts to funding for schools, hospitals and the police force. Climate change needs a response, but Mr Hammond is right to highlight the cost – and in fact, he is likely to be underestimating the real price-tag. Almost all signatories to the Paris Agreement on climate change are failing to live up to their promises. This is nothing new, countries have been failing to deliver ever since the Rio de Janeiro Earth Summit was held back...

Of all of the things that a government can do to influence the lives of citizens, immunisation is one of the most effective, cost-efficient investments. And a new, non-partisan report shows that expanding India’s immunisation programme would be a phenomenal investment. This is according to new research undertaken by India Consensus at the behest of the NITI Aayog.

You’ve probably seen the latest alarming headlines: Rising sea levels from climate change could flood 187 million people out of their homes. Don’t believe it. That figure is unrealistic—and it isn’t even new. It appears in a new scholarly paper, whose authors plucked it from a paper published in 2011. And what the earlier paper actually found was that 187 million could be forced to move in the unlikely event that no one does anything in the next 80 years to adapt to dramatic rises in sea level. In real life, the 2011 paper explained, humans “adapt proactively,” and “such adaptation can...

Ever notice how, in the last decade or so, we quietly stopped just having storms and started having “extreme weather events”? It feels like no temperature drop or seasonal downpour is too small for the media to slap a scary name on it and issue minute-by-minute warnings. Well, now some news outlets and campaigners are trying to do the exact same thing for climate change itself.

On the sidelines of the 2015 Paris climate summit, then-UK prime minister David Cameron and 19 other world leaders made a promise to double green energy research and development by 2020. The United Kingdom is on course to break that promise. As a percentage of GDP, spending on low-carbon energy R&D has stayed sluggishly around 0.02 per cent since 2015, according to data from the International Energy Agency (IEA).
