“Be the change you want to see”: How individuals (not only governments) are vital in cutting global CO2 emissions

What can we do in the face of the climate emergency? Many say we should drive less, fly less, eat less meat. But others argue that personal actions like this are a pointless drop in the ocean when set against the huge systemic changes that are required to prevent devastating global warming.  Research from a PhD researcher into Environmental Leadership (Cardiff University) shows that doing something bold like giving up flying can have a wider knock-on effect – by influencing others and shifting what’s viewed as “normal”.  These effects were increased if a high-profile person had given up flying, such as someone in the public eye.  Far from the small actions by individuals having no impact, they are important. The role of people, in changing their lifestyles, cutting their carbon emissions and environmental footprint, is as big as that of governments or major corporations.  But significant lifestyle changes by individuals need to be encouraged by effective government policy. It has to be both – policies, government action etc  PLUS actions by individuals. Millions of them. Behavioural change has the potential for far greater emission reductions than the political pledges made under the Paris Accord.



Climate change: yes, your individual action does make a difference


What can we do in the face of the climate emergency? Many say we should drive less, fly less, eat less meat. But others argue that personal actions like this are a pointless drop in the ocean when set against the huge systemic changes that are required to prevent devastating global warming.

It’s a debate that has been raging for decades. Clearly, in terms of global greenhouse gas emissions, a single person’s contribution is basically irrelevant (much like a single vote in an election). But my research, first in my masters and now as part of my PhD, has found that doing something bold like giving up flying can have a wider knock-on effect by influencing others and shifting what’s viewed as “normal”.

In a survey I conducted, half of the respondents who knew someone who has given up flying because of climate change said they fly less because of this example. That alone seemed pretty impressive to me. Furthermore, around three quarters said it had changed their attitudes towards flying and climate change in some way. These effects were increased if a high-profile person had given up flying, such as an academic or someone in the public eye. In this case, around two thirds said they fly less because of this person, and only 7% said it has not affected their attitudes.

I wondered if these impressionable people were already behaving like squeaky-clean environmentalists, but the figures suggested not. The survey respondents fly considerably more than average, meaning they have plenty of potential to fly less because of someone else’s example.

To explore people’s reasoning, I interviewed some of those who had been influenced by a “non-flyer”. They explained that the bold and unusual position to give up flying had: conveyed the seriousness of climate change and flying’s contribution to it; crystallised the link between values and actions; and even reduced feelings of isolation that flying less was a valid and sensible response to climate change. They said that “commitment” and “expertise” were the most influential qualities of the person who had stopped flying.

Letting fly

It’s not all a bed of roses, of course. Flying represents freedom, fun and progress. It boosts the economy and can provide precious travel opportunities. So suggesting that everyone should fly less, which may seem the implicit message of someone who gives up flying because of climate change, can lead to arguments and confrontation. One person for example said that my gently worded survey was “fascist and misinformed”. You don’t get that when you ask about washing-up liquid.

My research also probed ideas of inconsistency and hypocrisy. In short, people hate it. If Barack Obama takes a private jet and has a 14-vehicle entourage to get to a climate change conference, or a celebrity weeps for the climate while rocking a huge carbon footprint, it doesn’t go down well. And if future laws are introduced to reduce flying because of climate change, it looks essential that politicians will have to visibly reduce their flying habits, too. Other research has shown that calls for emissions reductions from climate scientists are much more credible if they themselves walk the talk.

At a meeting of academics on a research project into sustainable energy. Opening chat – “just flew in from Vienna & taxi from the airport – taxi booked for 4, as got to be back tonight” – no doubt they’ll make a wonderful & insightful contribution. Sadly half academics flew in!

57 people are talking about this

That people are influenced by others is hardly a shocking result. Psychology researchers have spent decades amassing evidence about the powerful effects of social influence, while cultural evolution theory suggests we may have evolved to follow the example of those in prestigious positions because it helped us survive. Pick up any book on leadership in an airport shopping mall and it will likely trumpet the importance of leading by example.

Which raises the question: if our political and business leaders are serious about climate change, shouldn’t they be very visibly reducing their own carbon footprints to set an example to the rest of us? This is now the focus of my research.

But why me?

Global emissions inequality. Oxfam

Weaving an invisible thread through all of the above is the thorny issue of fairness and inequality. The wealthiest 10% of the global population are responsible for 50% of emissions, and plenty of that will be due to flying. In the UK, around 15% of people take 70% of the flights, while half of the population don’t fly at all in any one year. As emissions from aviation become an ever increasing slice of the total (currently around 9% in the UK, 2% globally) this inequality will become harder for everyone to ignore.

In the mean time, the debate about personal vs. collective action will continue. My research supports the arguments that this is a false dichotomy: individual action is part of the collective. So, while you won’t save the world on your own, you might be part of the solution.



Be the change you want to see in the world: How individuals can help save the planet from climate catastrophe

Individuals have as big a role to play in tackling climate change as major corporations but only if they can be encouraged to make significant lifestyle changes by effective government policy, a major new European study co-authored by a University of Sussex academic has found.

The study notes that voluntary lifestyle choices by well-meaning individuals would only achieve around half the required emission reductions needed to hit the 1.5 C Paris Agreement goal. But the authors suggest that Paris targets could be achieved if voluntary choices were combined with policies that target behavioural change, particularly around eating meat and using fewer cars and airplanes.

The study’s authors say the international climate policy debate has so far focused mainly on technology and economic incentives, relegating behaviour change to a voluntary add-on. This is despite the fact behavioural change has the potential for far greater than the political pledges made under the Paris Accord.

The study, written by academics from 11 institutions including the University of Sussex, investigated the preferences for reducing household emissions, responsible for about 70% of global greenhouse gas emissions. It involved hundreds of families in four European cities using a specially-designed simulation tool to indicate carbon and money savings from 65 lifestyle choices combined with in-depth surveys with household members.

It found  for policy initiatives that encouraged more  around food production but resistance to initiatives that restricted personal mobility and transport options. The study also found that ironically the areas where greatest lifestyle changes were required and the largest carbon footprints produced, such as aviation and changes to diet, had received the lowest policy attention to date.

Lead author Ghislain Dubois, founder of the TEC Conseil in France, said: “Our research proves that if supported by adequate policies, households can have a decisive contribution to the Paris agreement objectives. This is largely ignored by current climate policies and negotiations, which rely only on macro-economics and technology. We should dare envisaging and doing research on taboos like consumption reduction or sobriety. When you consider the impacts on CO2 emissions, but also on households’ budgets and the potential co-benefits, it is worth it.”

Professor Benjamin Sovacool, second author of the study and Director of the Sussex Energy Group at the University of Sussex, added: “Our study underscores the contradictions we all have in balancing climate change with other priorities. We want to fight climate change, but stick to eating meat and driving our cars. There are certain changes we can make voluntarily but beyond that we need policy to step in.”

The study, published in the upcoming June edition of Energy Research and Social Science, found that the greater the potential actions have to reduce emissions, the less households were willing to implement them. In these areas “forced” solutions such as a considerably higher carbon tax on fuel and regulations encouraging food producers to reduce packaging or increase local and organic farming in addition to voluntary measures will be needed, the academics warn.

Carlo Aall, co-author of the study from the Western Norway Research Institute, said: “There is political room for taking a tougher stand on supporting economically and regulating household consumption to become more climate friendly. Meat consumption and long air trips in particular need to be addressed.”

Alina Herrmann, co-author from the Heidelberg Institute for Global Health said: “Strikingly, people were very open to climate friendly solutions in the food and recycling sector. We have found strong support for less packaged food, more sustainable food production and moderate reduction of meat consumption in our study population. Many participants even wished for external support to make such sustainable choices easier for them.”

However, in areas such as mobility, the authors recommend limiting the availability of greenhouse gas-intensive consumption through regulative instruments such bans, restrictions or increased taxes; balanced with making low-carbon alternatives more readily available.

Dr. Hermann added: “Changing mobility behaviour was seen as incredibly difficult. To gain acceptance for reduced mobility as part of societal transformation in the face of , and entirely new public discourse would be needed.”

Responses from the study revealed household carbon footprints are not static but can fluctuate significantly with major life events such as having children, experiencing illness or retiring.

The authors recommend that targeted interventions at these milestones could be highly effective in bringing about long-lasting change and suggested that intermediaries at these milestones, such as estate agents, car sales staff and retirement planners, could all play a much more active role in identifying carbon-reducing options.
