Using Behavioral Science to Encourage Sustainable Consumer Demand

Sustainable Banking

HIGHLIGHTS

  • Banks may lend money in deposit accounts to various corporations, including fossil fuel companies

  • Switching to sustainable banks can reduce the funds available to the fossil fuel sector 
  • A behavioral lens can help address barriers to switching and support consumers’ environmental values

The Challenge

Seven in 10 people in the US now recognize that climate change is happening, and six in 10 believe that it is human-caused. But despite increasing concern surrounding climate change, it is difficult to align our own individual everyday decisions and actions to create positive impact—or avoid negative impact—on the environment. One area where many environmentally minded consumers don’t consider the impact of their behavior is personal banking. 

In the United States, many of us have heard about sustainable investing, or choosing to buy stock in companies that are committed to positive social and environmental impact. But the money in deposit accounts—checking, savings, money market accounts, and certificates of deposit—also affects the world outside the bank vault. Banks leverage these deposits to make loans to various corporations, including fossil fuel companies. In fact, North American banks are the biggest lenders and underwriters of fossil fuel projects. Research suggests that merely continuing to use existing fossil fuel infrastructure until the end of its life imperils the Paris Agreement goal of limiting warming to 1.5ºC. Financing new fossil fuel exploration and infrastructure virtually ensures we will exceed that limit. 

The opportunity is large: 93% of US households have a checking or savings account, while only 52% own stock. Focusing efforts only on sustainable investing not only excludes many people from the conversation, it creates a missed opportunity for environmentally minded consumers who want to use their daily decisions to support the environment. By switching our bank accounts to accounts that don’t finance fossil fuel projects, not only can we directly reduce the amount of funds available to the fossil fuel sector, but we can also increase funds for community and clean energy investment. 

Our Approach

The Climate and Environment Team at ideas42 has partnered with two sustainable financial institutions to understand and encourage consumer demand for deposit accounts that fund socially and ecologically sustainable investments. Our first partner, Self-Help Federal Credit Union, has a long legacy of providing financial services to underserved communities and is committed to fossil-free, mission-aligned lending practices. Our second partner, Aspiration, is a fintech provider of sustainable checking and savings accounts, as well as two sustainable investment funds. Alongside these partners, we’ve been learning about what behavioral barriers prevent consumers concerned about climate change from opening sustainable deposit accounts and designing interventions to address these barriers. 

We published a report documenting our findings and sharing behavioral insights for the benefit of all sustainable finance providers and stakeholders—and people who want to use their choices to help the environment. The report, Bank on What You Believeincludes an outline of the relationship between retail banks and the fossil fuel industry, an overview of the work we’ve done with our sustainable financial institution partners, and the main behavioral barriers preventing well-intentioned consumers from switching to sustainable bank accounts.

When it comes to switching to a sustainable banking option, we found that behavioral barriers fit into the following engagement areas:

  • most consumers don’t recognize the links between where they keep their money and climate change (or aren’t aware of sustainable banking as an option),
  • most consumers don’t consider their banking behavior as a means for social change, and
  • many consumers don’t act to switch accounts even if they want to do so

Behavioral barriers impact consumers’ abilities to recognize, consider, and act, often preventing people from using a bank that aligns with their environmental values. We uncovered these barriers (detailed in the report) with a behavioral lens, and we believe that behavioral science can help to create solutions for turning everyday actions into social change.

Takeaway

Going forward, we encourage our partners and other institutions will test interventions to help people overcome these barriers. A movement of consumers holds promise not only to demonstrate a moral and ethical standard for banks to uphold, but also to grow the business potential in the sustainable banking space—and the reputational risk of maintaining the status quo.

Consumers, sustainable financial institutions, and advocates will all have roles to play in mobilizing the financial sector away from fossil fuels and toward a clean and just economy. Along the way, we can discover and leverage behavioral strategies to help more people drive informed, values-based, empowered action in service of a better world for all.
