Promoting climate-friendly behaviours will be more successful in societies where everyone has the capacity: financially, physically, and timewise, to make changes.
Researchers argue that tackling inequality is vital in moving the world towards Net-Zero – because inequality constrains who can feasibly adopt low-carbon behaviours. They say that changes are needed across society if we are to mitigate climate change effectively. Although wealthy people have very large carbon footprints, they often have the means to reduce their carbon footprint more easily than those on lower incomes.
"People on lower incomes can be more restricted in the things they can do to help reduce their carbon footprint,"
"She added: “People on lower incomes can be more restricted in the things they can do to help reduce their carbon footprint, in terms of the cost and time associated with doing things differently,” Dr Charlotte Kukowski, Dept of Psychology
The researchers say there is lack of political recognition of the barriers that can make it difficult for people to change to more climate-friendly behaviours. They suggest that policymakers provide equal opportunities for low-carbon behaviours across all income brackets of society. The report defines inequality in various ways: in terms of wealth and income, political influence, free time, and access to low-carbon options such as public transport and housing insulation subsidies.
The researchers found that deep-rooted inequalities can restrict people’s capacity to switch to lower-carbon behaviours in many ways. For example: Insulating a house in the UK can be costly, and government subsidies are generally only available for homeowners; renters have little control over the houses they live in.
The UK has large numbers of old, badly insulated houses that require more energy to heat than new-build homes. The researchers call for appropriate government schemes that make it more feasible for people in lower income groups to reduce the carbon emissions of their home. Cooking more meat-free meals: plant-based meat alternatives currently tend to be less affordable than the animal products they are trying to replace.
Eating more plant-based foods instead of meat and animal-derived products is one of the most effective changes an individual can make in reducing their carbon footprint. Buying an electric car or an electric bike is a substantial upfront cost, and people who aren’t in permanent employment often can’t benefit from tax breaks or financing available through employer schemes.
