To keep global warming below 1.5°C, greenhouse gas emissions had to peak no later than 2025. That was a key finding of the IPCC’s most recent major report on the topic, published a few years ago. Yet when we surveyed UK MPs and members of the public in four countries, fewer than 15% could identify this deadline correctly.
This matters. If politicians and voters underestimate how urgently we have to fight climate change, they are less likely to back the tough policies needed. Instead, they risk assuming we have more time, all while climate change targets slip further out of reach.
Our study, published in the journal Communications Earth and Environment, found that across Britain, Canada, Chile and Germany, about one-third of respondents thought emissions only had to peak by 2040 or later. In the UK, we also surveyed MPs. We found Labour politicians were more likely than Conservatives to answer correctly, but overall awareness was low in both groups.
