Role of individual actions in emissions reduction explored in new WRI report

The role that individual actions – such as changing how we eat, travel and power our homes – can play in terms of overall emissions reduction is the subject of a new working paper by the World Resources Institute.

The WRI’s report, The Effective Impact of Behavioral Shifts in Energy, Transport, and Food, finds that when people are ‘nudged’ to make personal changes without broader shifts in the surrounding environment, the potential emissions reductions top out at around 10%.

According to the WRI, unlocking the remaining 90% emissions will require systemic support, with the need for stronger national and subnational policies and company actions to make sustainable choices easier for all.

“Our data shows that pro-climate behaviour changes, such as driving less or eating less meat, could theoretically cancel out all the greenhouse gas (GHG) emissions an average person produces each year — specifically among high-income, high-emitting populations,” commented Mindy Hernandez, director, Living Lab for Equitable Climate Action, World Resources Institute.

“But it also reveals that efforts focused exclusively on changing behaviours, and not the overarching systems around them, only achieve about one-tenth of this emissions-reduction potential. The remaining 90% stays locked away, dependent on governments, businesses and our own collective action to make sustainable choices more accessible for everyone.”

Behavioural changes

The report also explores the behavioural changes that have the biggest potential to cut emissions, with a notable difference evident depending on certain behaviours – for example, living without a car is 78 times more effective at reducing emissions than composting.

It also looks at the strategies to promote behavioural change that are proven to work best, with the most effective being based on choice architecture – making green options the default or more attractive — and commitment devices, such as pledges.

However, according to the WRI, commonly-used tools such as carbon footprint calculators and awareness campaigns rank among the least effective ways in which to prompt behavioural change.

“While our choices matter for the climate, the ‘carbon footprint’ narrative has obscured where our true power lies,” Hernandez added. “This individualistic framing fragments our collective strength, keeping us focused on isolated personal behaviours rather than the transformative power of collective action.

“WRI’s research suggests a more impactful path forward. Rather than calculating our carbon math, our most meaningful individual action may be expanding our collective civic footprint. This can transform not just what we consume, but what choices exist for everyone.” Read more here and here.
