Review from Carbon Brief on a new research paper exploring the relationship between household energy footprint and well-being in the UK.
The wealthiest people in the UK burn through more energy flying than the poorest use in every aspect of their lives, according to new research.
The analysis of data from 2019 highlights “significant inequalities” in energy use across the country. Those in the top 10% of incomes used nearly three times as much energy in a year as people in the bottom 30%.
This was particularly true for transport. Car journeys and flights taken by the richest British people – especially “white, wealthy middle-aged men” – used more energy that year than 60% of the population got through in total.
The authors of the study, published in Ecological EconomicsOpens in a new tab, say energy consumption is currently “too high” to achieve the world’s climate targets, even as many indulge in “excess energy use” while millionsOpens in a new tab languish in fuel poverty.
Yet, by combining their energy analysis with measures of wellbeing, they conclude that a high standard of living can be achieved in the UK with relatively low levels of energy consumption.
Experts tell Carbon Brief that this research should encourage those in power to devise policies that target the excessive energy use of the rich, such as frequent flyer leviesOpens in a new tab.
The study assesses the annual “energy footprint” of people in the UK. This includes a detailed breakdown of the energy used for everything from building their furniture to powering the restaurants where they eat.
Those in the global north are known to be disproportionately responsible for both energy use and greenhouse gas emissions. The average person in the UK uses roughly four times as much energy in a yearOpens in a new tab (pdf) as someone in India and 21 times as much as someone in east Africa.
But within these relatively high-income nations there are large variations in wealth and the energy intensity of people’s lifestyles.
In order to assess the energy use of different activities, the team led by Dr Marta BaltruszewiczOpens in a new tab, as part of the Living Well Within LimitsOpens in a new tab project at the University of LeedsOpens in a new tab, drew together a range of datasets concerning British people’s lives.
In particular, they merged data collected in 2019 for the UK living costs and food surveyOpens in a new tab conducted by the Office of National StatisticsOpens in a new tab (ONS) and Understanding SocietyOpens in a new tab, a wide-ranging survey touching health, work, social life and other subjects, conducted by the University of Essex.
This approach allowed them to isolate how much energy people in different income brackets used for different activities. The chart below shows this breakdown.
Energy footprints of British households in 2019 by income grouping, where 1 is the lowest income 10% of the population and 10 is the highest income 10%. Footprints are measured in gigajoules (GJ) per “adult equivalent”, which is based on dividing the energy use of a household by the number of people, accounting for the fact that children contribute less.

The inequality is huge. In 2019, the wealthiest 10% of people in the UK used around three times as much energy driving cars and five times as much for recreational activities, when compared to the bottom 10%.
One of the greatest disparities came from people’s use of planes. Domestic and international flights taken by people with the highest incomes used around five times more energy than those taken by the poorest.
In fact, as the chart below shows, the 102 gigajoules (GJ) used for flying by the average adult in the top 10% of earners in that year was more than the average person in the bottom fifth of earners used for everything, including flying, driving and heating their homes.

Transport experts tell Carbon Brief the figures for air travel are in line with their expectations. “Most people are not aware that 70% of the flights taken in this country are by just 15% of the population,” says Matt FinchOpens in a new tab, UK policy manager at the NGO Transport & EnvironmentOpens in a new tab.
Baltruszewicz and her team were also able to assess who precisely was responsible for “unabated excess energy” use. They found that “those who most often overshoot energy use are white, wealthy middle-aged men”. By comparison, Baltruszewicz tells Carbon Brief:
“Those who are most energy poor…They also tend to be non-white, female [and] rent houses…there is so much social injustice engrained in those who don’t have enough energy.”
Prof Ian GoughOpens in a new tab from the London School of EconomicsOpens in a new tab, who has conducted research in this field, but was not involved in the study, notes that bringing together a variety of datasets allowed the researchers to single out detailed components such as international flights in a “very powerful way”.
With the wealth of data at their disposal, the researchers were able to link UK energy use to different measures of wellbeing including health, loneliness and energy poverty.
They used the metrics available to set an overall “wellbeing score”. The relationship between this score and increasing levels of energy use can be seen in the chart below.
It shows that at the lower end of the energy use spectrum, wellbeing initially increases a lot as energy footprint rises. But there are “diminishing or no returns” as energy use gets higher. There is also a large range within each group, reflecting the number of factors at play.
The average British person the researchers classed as having “high wellbeing” used 183GJ of energy in 2019, compared to the average value of 156GJ.
However, they also found that around one-quarter of those living on less than 100GJ per year also scored highly for wellbeing. These people tended to fly and drive much less, and own a house in an urban area.
The authors conclude that “excess” energy use is not essential for a high quality of life.
However, they also emphasise that living a low-energy lifestyle depends on many factors. For example, people living in uninsulated houses in rural areas might require more energy to keep them warm or drive their car, due to the lack of public transport.
Despite this complexity, Baltruszewicz says there are energy uses that clearly need to be addressed. In particular, she points out that despite its popularity among the rich, there is little correlation between flying and wellbeing scores:
“So why do we still develop infrastructure for flying…Why do we facilitate something that clearly doesn’t contribute to societal wellbeing, but is also destroying our climate?”
Demand for change
Dr Mari MartiskainenOpens in a new tab, a professor of energy and society at the University of SussexOpens in a new tab who was not involved in the research, tells Carbon Brief the results are particularly important in the context of a cost-of-living crisis:
“It’s also really important that we start to have these discussions on what is the socially acceptable level of energy consumption…What kind of society do we live in if we have people that have massive amounts of excess energy consumption [who] will then make climate change a lot worse for everyone else, versus people who can’t afford to heat their homes?”
The study comes at a fraught time for UK climate and energy policy.
Russia’s invasion of Ukraine has exposed many British households to unaffordable hikes in energy costs, with more than 8m households facing fuel poverty in the coming months.
From the outset, many European nations respondedOpens in a new tab to the crisis by encouraging their citizens to reduce their energy use. Yet until recent weeksOpens in a new tab, the UK government seemed ideologically opposed to such measures.
In general, the Conservative leadership has rejectedOpens in a new tab any climate policies that they perceive as infringing on people’s personal choices and even introducedOpens in a new tab new subsidies to encourage domestic flights in the UK.
The government’s net-zero plans for aviationOpens in a new tab and carsOpens in a new tab have both come under fire for ignoring the need to reduce demand. The overarching net-zero strategyOpens in a new tab says it intends to “go with the grain of existing behaviour and trends”.
This is despite criticismOpens in a new tab from the government’s own climate advisers, the Climate Change CommitteeOpens in a new tab. They have warned that roughly one-thirdOpens in a new tab of emissions cuts needed by 2035 to stay on course for net-zero will involve people changing their behaviour.
Martiskainen says it is important that these topics are addressed, but tells Carbon Brief she is sceptical about whether they will be: “Imagine the headlines in the Daily Mail.”
For her part, Baltruszewicz says she hopes this research will provide “ammunition for policy makers who would like to target high energy users”. She emphasises the importance of public transport and housing efficiency improvements to help everyone reduce their energy footprints, but says this “will not be enough”.
Her study highlights the need for interventions, such as frequent flyer levies, to target wealthy, high-energy users and avoid outcomes that are “disastrous for all”.
