A poll of 2,000 adults found 61 per cent believe they have a responsibility to live a sustainable lifestyle, while 58 per cent see being environmentally conscious as a 'badge of honour'.
In fact, the average adult claims to be 29 per cent greener than they were 10 years ago, as they make more sustainable choices than ever before.
Now, the average person typically carries out 369 eco-friendly acts a year – more than one per day – compared to just 286 a year a decade ago.
It also emerged 52 per cent believe it is no longer socially acceptable to turn a blind eye to environmentally issues.
And 54 per cent would be embarrassed to be seen as living unsustainably.
Nearly two thirds (62 per cent) feel they have a better understanding of how to lead an eco-friendly lifestyle than ever before.
A quarter credit social media for motivating them to make a difference, while 27 per cent claim campaign groups such as Extinction Rebellion have convinced them to change their habits.
Recycling, eating less meat and avoiding single-use plastics are among the most common eco-friendly acts carried out today, with 55 per cent proud to ‘do their bit’.
Lowering the carbon footprint
However, the research commissioned by Trainline, identified a limited understanding of which eco-friendly acts have the biggest impact on the environment.
Just 17 per cent of believe swapping one long-distance car or plane journey for train travel would have a significant positive impact on the environment.
While 53 per cent are not aware cars have a higher carbon footprint than trains, and 60 per cent didn't know travelling by plane can emit seven times more CO2 per passenger kilometre than by train.
As a result, only 19 per cent are currently making efforts to travel by train more often in a bid to save the planet, and just a quarter plan to cut down on non-essential travel in the next 10 years.
Mike Hyde, chief data officer at Trainline, said: “It is fantastic to see that the UK is motivated to take responsibility for improving the environment and this has led to a wide range of lifestyle changes to live more sustainably.
“However, we were shocked so many people are unaware of how beneficial swapping just one long-distance car or plane journey to train would be to the planet.”
Gen-Z are fighting for change
The study, carried out through OnePoll, also found 37 per cent said providing a better future for the next generation is their biggest motivator for living a more sustainable and environmentally friendly lifestyle.
And Gen-Z are most likely to be vocal about their desire to protect the environment, with 79 per cent having conversations with friends and family to try to help them to live more sustainably.
But 21 per cent of 18-34-year-olds believe living sustainably is the most important factor in their lifestyle – equal to how much money they have in the bank.
And 41 per cent claim they would ‘happily’ pay more for their clothes and food to be sustainably sourced.
It comes after a separate study of 2,500 adults, by Trainline, found 66 per cent of 18–30-year-olds have changed their lifestyle to reduce their impact on climate in the past year alone.
While 49 per cent have switched to travelling by train instead of another mode of transport at least once during the past 12 months, to reduce their carbon footprint of their journey.
Mike Hyde added: “We know that taking the train instead of driving creates 70 per cent less CO2 on average.
"We want to raise awareness of the impact your travel choices can have on the environment and ensure that we make train travel as easy and accessible as possible, with the aim of encouraging more people to travel by rail.”
