With aviation and cruise set for the first time to be included in the UK’s next carbon budget, due this month, how can travel continue to grow while reducing its environmental impact? Gary Noakes reports.

Later this month, the latest advice on how the UK can cut its greenhouse gas emissions will be published by the Climate Change Committee (CCC) – the independent body that advises parliament – with aviation and shipping set to be included for the first time.

The recommendations of the committee to government will shape the UK’s next carbon budget, which sets binding targets for reducing emissions to help the UK move towards net zero.

So what is a carbon budget, and what does it mean for travel?

Under the 2008 Climate Change Act, the UK is legally required to reduce greenhouse gas emissions by at least 100% compared with 1990 levels by 2050.
