The Best Robo-Advisors for Sustainable Investing

You're inspired by the idea of sustainable investing. You want to build a portfolio that not only grows your wealth but also reflects your values and contributes to a better world. You've read the "Beginner's Guide to ESG Investing" and you're ready to take action.

But then you're faced with a daunting task: researching hundreds of funds, decoding ESG scores, and building a diversified portfolio from scratch. It can feel overwhelming.

What if there was a way to get a professionally managed, globally diversified, and ethically screened portfolio in just a few clicks?

Welcome to the world of robo-advisors. These automated investment platforms have revolutionized investing, and many now offer specialized portfolios for socially responsible investing (SRI). This guide will break down the best robo-advisors for sustainable investing, helping you choose the right platform to put your money to work for you and for the world.

What Is a Robo-Advisor and Why Use One for Sustainable Investing?

A robo-advisor is an online platform that uses algorithms to build and manage a diversified investment portfolio for you. You simply answer a series of questions about your financial goals, timeline, and risk tolerance, and the platform handles the rest. It's one of the simplest and most effective ways to start investing.

So, why are they a great choice for ESG investing?

1. Simplicity and Accessibility: Robo-advisors remove the biggest barriers to entry. You don't need a huge amount of money to start (many have low or no minimums), and you don't need to be an expert. They make it incredibly easy to get started.
2. Automated Diversification: They automatically build you a portfolio that is spread across different asset classes (like US stocks, international stocks, and bonds), which is crucial for managing risk.
3. Professional Screening: The best platforms have already done the hard work of vetting and selecting a range of low-cost, high-quality ESG funds. They build a complete SRI portfolio for you, saving you countless hours of research.
4. Disciplined Automation: Robo-advisors keep you on track. They automatically rebalance your portfolio to keep it aligned with your goals and facilitate automatic deposits, which helps you "automate your savings" and avoid the pitfalls of emotional investing.

In short, a robo-advisor can be the perfect partner for anyone who wants to "build an ethical investment portfolio that actually performs" without the complexity of doing it all yourself.

How We Evaluated the Best Robo-Advisors

To determine the best platforms, we focused on the criteria that matter most to a socially conscious investor:

• Quality of SRI/ESG Portfolios: How robust and transparent is their sustainable investing option? Do they offer customization?
• Management Fees: How much does the service cost? We prioritized platforms with low, transparent fees.
• Account Minimums: How much money do you need to get started? We looked for platforms that are accessible to everyone.
• Features and User Experience: How easy is the platform to use? Does it offer other useful features like financial planning tools or access to human advisors?

With that framework, let's dive into our top picks.

1. Betterment: The Best Overall for Comprehensive ESG Options

Why is Betterment our top pick?

Betterment is one of the largest and most respected robo-advisors, and they have made a serious commitment to providing robust options for sustainable investing. Their platform offers a fantastic blend of simplicity, low fees, and meaningful customization, making it the best all-around choice for most people.

Betterment doesn't just offer one SRI portfolio; they offer three distinct choices, allowing you to select the level of impact that best aligns with your values.

Betterment's ESG Portfolio Options:

1. Broad Impact Portfolio: This is their core ESG offering. It tilts your portfolio toward companies with higher ESG ratings according to MSCI, a leading ESG data provider. It invests in funds like the iShares ESG Aware MSCI USA ETF (ESGU).
2. Climate Impact Portfolio: This portfolio is specifically designed for investors whose primary concern is climate change. It focuses on companies that are actively reducing their carbon emissions and funds green projects, while divesting from companies with fossil fuel reserves. It's a great tool for building a "fossil fuel-free portfolio."
3. Social Impact Portfolio: This portfolio focuses on the "S" in ESG, tilting investments toward companies that are leaders in promoting minority empowerment and gender diversity.

Key Details:

• Management Fee: 0.25% per year for the Digital plan (a $25 fee on a $10,000 investment).
• Account Minimum: $0.
• What We Love: The choice of three distinct ESG portfolios gives you real control. Their transparency is excellent; you can easily see exactly which ETFs are in each portfolio and why they were chosen. The platform is incredibly user-friendly and offers great goal-setting tools.
• What to Consider: While their options are great, they are still pre-built portfolios. You can't swap out individual funds you don't like.

The Bottom Line: For the vast majority of investors who want a simple, effective, and reasonably priced way to start sustainable investing, Betterment is the clear winner.

2. Wealthfront: The Best for Low Fees and Customization

Why is Wealthfront a top contender?

Wealthfront is another industry giant known for its extremely low fees and powerful, tech-forward platform. While their core SRI portfolio is less comprehensive than Betterment's, they offer a game-changing feature for socially conscious investors: the ability to customize your portfolio and exclude specific companies or industries.

Wealthfront's Approach to Sustainable Investing:

Wealthfront offers a core SRI portfolio that uses a curated list of ESG, SRI, and low-carbon ETFs. The real power, however, comes from their customization features, which are available for accounts over $100,000. You can start with their SRI portfolio and then:

• Exclude Individual Stocks: Don't want to own a specific company, even if it's in an ESG fund? You can add it to an exclusion list.
• Restrict Industries: You can easily screen out entire sectors like fossil fuels, tobacco, or weapons.

Key Details:

• Management Fee: 0.25% per year (same as Betterment).
• Account Minimum: $500.
• What We Love: The combination of a low-cost robo-advisor with the power to customize and exclude specific stocks is a huge advantage for investors with strong convictions. Their digital financial planning tools are among the best in the business.
• What to Consider: The best customization features are reserved for larger accounts. Their default SRI portfolio is a single option, unlike Betterment's three distinct choices.

The Bottom Line: If you want the automation of a robo-advisor but crave a bit more control to fine-tune your portfolio's ethical screen, Wealthfront is an exceptional choice, especially as your assets grow.

3. M1 Finance: The Best for Hybrid "DIY" Ethical Investing

Why is M1 Finance a unique and powerful option?

M1 Finance is not a traditional robo-advisor. It's a unique hybrid platform that combines the automation of a robo-advisor with the control of a traditional brokerage account. This makes it an incredibly powerful tool for the hands-on ethical investor.

How M1 Finance Works for Sustainable Investing:

Instead of answering questions to get a pre-built portfolio, you build your own custom portfolios, which M1 calls "Pies." You can create a Pie made up of the specific ESG ETFs and even individual stocks that you choose.

• Expert Pies: M1 offers pre-built "Expert Pies," including several Socially Responsible options that you can use as a starting point.
• Ultimate Customization: You can build your own Pie from scratch. Want a portfolio that is 50% in the iShares ESG Aware ETF (ESGU) and 50% in the iShares Global Clean Energy ETF (ICLN)? You can build that in two minutes. Want to add a slice for Tesla or another company you believe in? You can do that too.
• Automation: Once you've built your Pie, M1 automatically manages it for you. Every time you deposit money, it is automatically invested across your chosen slices, and they handle the rebalancing.

Key Details:

• Management Fee: $0. M1 Finance does not charge a management fee. They make money in other ways, such as interest on cash balances.
• Account Minimum: $100.
• What We Love: The unparalleled control and customization, combined with zero management fees, is an unbeatable combination for the cost-conscious, hands-on investor.
• What to Consider: It requires more work and knowledge than a true robo-advisor. You are responsible for choosing your own investments, which means you need to do your own research and be confident in your choices. It's easy to build a poorly diversified portfolio if you're not careful.

The Bottom Line: For the investor who has done their research (perhaps by reading our list of the "Top 5 ESG ETFs") and wants to build a specific, custom ethical portfolio with zero management fees, M1 Finance is in a class of its own.

4. Ellevest: The Best for a Gender-Lens and Impact Investing Focus

Why is Ellevest a standout choice?

Ellevest is a unique investment platform with a mission to get more money in the hands of women. Their entire investment philosophy is built around impact investing, with a specific focus on companies that advance women's economic and social standing.

Ellevest's Approach to Impact Investing:

Ellevest's portfolios are designed to invest in companies with strong policies on gender diversity, fair labor practices, and sustainability. They construct their portfolios using a range of mutual funds and ETFs that score highly on these metrics. Their primary impact fund, the Ellevest Intentional Impact Portfolios, focuses on companies that:

• Have women in leadership.
• Provide fair pay and benefits.
• Have a strong record on sustainability.

Key Details:

• Management Fee: Ellevest uses a membership model. Plans start at $12 per month.
• Account Minimum: $0.
• What We Love: Their clear, mission-driven focus on gender-lens investing is unique in the robo-advisor space. It's a fantastic choice for investors who want their money to specifically support women's advancement. The platform also offers excellent financial planning and career coaching resources.
• What to Consider: The membership fee model can be more expensive than a traditional percentage-based fee, especially for smaller account balances. Their focus is specific, so it may not be the right fit for someone whose primary concern is purely environmental.

The Bottom Line: For investors who are passionate about gender equality and want a platform that aligns completely with that mission, Ellevest is the best and most authentic choice on the market.
