The Best Robo-Advisors for Sustainable Investing
The Sustainable Robo-Advisor Landscape: A 2025 Reality Check for Values-Driven Investors
When Maya decided to align her investments with her environmental values, she assumed choosing a "sustainable" robo-advisor would be straightforward. She quickly discovered a confusing landscape where "ESG" could mean anything from comprehensive impact screening to merely excluding tobacco companies.
"I found myself questioning whether my money was actually creating change or just supporting marginally 'less bad' companies," she recalled. "The sustainable investing options felt like a black box—impossible to understand what I was really investing in."
Maya's frustration reflects a broader challenge in the robo-advisor space. While sustainable investing has gone mainstream, the depth and authenticity of these offerings vary dramatically. After testing and analyzing over a dozen platforms, we've developed a framework to help you find robo-advisors that deliver both competitive returns and genuine impact.
The Sustainable Robo-Advisor Reality Gap
Independent research confirms what Maya discovered: most robo-advisors offer limited sustainable investing options. A 2025 analysis found that only half of top-ranked platforms provide any dedicated sustainable portfolios, and those that do often have significant limitations [citation:6].
The most common gaps include:
Partial Portfolio Sustainability: Many platforms use sustainable ETFs for equity allocations but conventional funds for fixed income, creating a partially-aligned portfolio that may still include fossil fuel investments or companies with poor labor practices.
No Values Assessment: Unlike the detailed risk questionnaires used to determine investment strategy, no major robo-advisor offers a comprehensive values assessment to match investors with sustainability approaches that reflect their specific priorities [citation:6].
Limited Impact Reporting: Very few platforms provide concrete reporting on the environmental or social impact of your investments, making it difficult to understand what difference your money is actually making.
The Three-Tier Framework for Evaluating Sustainable Robo-Advisors
To bring clarity to this complex landscape, we developed a simple three-tier classification system that goes beyond marketing claims to assess the actual depth of sustainable investing options.
Tier 1: Basic ESG Integration
These platforms offer sustainable investing primarily through ESG-screened ETFs that exclude controversial industries like fossil fuels, tobacco, or weapons. While better than conventional investing, this approach represents the minimum threshold for sustainability.
What you get: Portfolio construction using broad ESG ETFs from providers like iShares or Vanguard that typically screen out the worst offenders while maintaining diversification.
What's missing: Limited ability to target positive impact themes, conventional fixed income holdings, and no customization based on specific values.
Platform example: E*Trade offers socially responsible ETF options but integrates them into otherwise conventional portfolio construction, earning a sustainability score of 1 out of 3 in independent assessments [citation:6].
Tier 2: Themed Sustainable Portfolios
This middle tier represents platforms that have developed dedicated sustainable portfolios with more thoughtful construction and clearer impact themes.
What you get: Purpose-built sustainable portfolios that may focus on specific themes like climate solutions, gender diversity, or clean energy. These platforms typically use multiple ESG ETFs to create more comprehensively sustainable exposure.
What's missing: Impact measurement is still limited, and portfolio customization options may be restricted to a few pre-set themes rather than aligning with your specific values.
Platform examples: Four of the five top platforms offering sustainable options fall into this category, including TD Ameritrade, Betterment, Ellevest, and Wealthsimple, all scoring 2 out of 3 for their sustainable offerings [citation:6].
Tier 3: Comprehensive Impact Solutions
The most advanced platforms in this category treat sustainability as a core design principle rather than an add-on option. They offer the deepest alignment between investor values and portfolio construction.
What you get: Fully sustainable across asset classes, values-based customization, impact reporting, and in some cases, the ability to focus on specific impact themes that matter most to you.
What's missing: These comprehensive solutions remain rare in the robo-advisor space, though a few platforms are moving in this direction.
Platform example: While no platform achieved a perfect score of 3 in recent research, Wealthsimple stands out for offering three distinct responsible investing portfolios constructed with sustainable equity ETFs and including at least one sustainable fixed income ETF, moving beyond equity-only sustainability [citation:6].
Detailed Platform Analysis: Beyond the Marketing Claims
Wealthsimple: Broad Accessibility with Growing Options
As Canada's largest robo-advisor, Wealthsimple has made responsible investing a central part of its offering [citation:1]. Their approach includes three portfolio options (Conservative, Balanced, Growth) built using sustainable ETFs.
Sustainable investing approach: Portfolios use ESG-screened equity ETFs and include some sustainable fixed income exposure, though they still incorporate conventional ETFs to maintain diversification [citation:6].
Fees: Management fees range from 0.40% to 0.50% for most accounts, with lower tiers available for larger balances [citation:1].
The bottom line: Wealthsimple offers one of the more accessible entry points to sustainable investing with its user-friendly platform and clear responsible investing options. However, their sustainability implementation still has room for improvement, particularly in fixed income and impact reporting.
Betterment: ESG Customization Within Limits
Betterment takes a structured approach to sustainable investing, using Climate Impact, Social Impact, and Broad Impact portfolios to cater to different investor preferences.
Sustainable investing approach: Their target asset allocation strategies rely on iShares MSCI ETFs that use ESG scoring and exclusions to construct portfolios. However, like many platforms, they combine these with conventional ETFs, particularly for fixed income allocations [citation:6].
Fees: Competitive management fees of 0.25% make Betterment an affordable option for values-based investors [citation:2].
The bottom line: Betterment offers more thematic choice than many competitors but still faces the common limitation of partial portfolio sustainability.
Justwealth: Targeted Options for Specific Values
While less comprehensive in their sustainability approach than some competitors, Justwealth deserves mention for their socially responsible investment (SRI) portfolio options and strong performance track record [citation:10].
Sustainable investing approach: Offers dedicated SRI portfolios with MERs ranging from 0.25% to 0.40%, slightly higher than their standard ETFs but competitive for sustainable options [citation:10].
Unique advantage: Every client gets assigned a personal financial planner, which can be invaluable for discussing your specific values and how they align with different sustainable investing approaches [citation:10].
The bottom line: Justwealth combines solid sustainable options with human guidance, making it a good choice for investors who want some sustainability focus alongside personal support.
The Fee Reality: What Sustainable Investing Actually Costs
One persistent myth about sustainable investing is that it requires paying premium fees. The reality in 2025 is more nuanced:
Robo-Advisor Fee Comparison for Sustainable Portfolios
- Wealthsimple: 0.40%-0.50% management fee + 0.12%-0.50% MER [citation:1]
- Betterment: 0.25% management fee [citation:2]
- Justwealth: 0.40%-0.50% management fee + 0.25%-0.40% MER for SRI options [citation:10]
- Questwealth: 0.20%-0.25% management fee (among the lowest) [citation:1]
While sustainable portfolios typically carry slightly higher MERs due to the additional research and screening required, the difference has narrowed significantly. For most investors, the premium amounts to 0.05%-0.15% annually—a small price for alignment with your values.
5 Critical Questions to Ask Before Choosing a Sustainable Robo-Advisor
Based on our analysis of the landscape, these questions will help you identify platforms offering genuine sustainability rather than surface-level greenwashing:
1. "Is my entire portfolio sustainable, or just the equity portion?"
Many platforms neglect fixed income sustainability. Ask specifically about bond holdings and whether they include fossil fuel financing or other problematic investments.
2. "What specific methodology do your ESG funds use?"
Look for transparency around whether funds use best-in-class screening, norm-based exclusions, or impact weighting. This reveals the depth of their sustainability approach.
3. "Can I see impact reports or metrics for my portfolio?"
Regular reporting on carbon footprint, diversity metrics, or other impact measures demonstrates a commitment to transparency beyond initial portfolio construction.
4. "How customizable are the sustainable options?"
If you have specific values around climate, social justice, or governance issues, understand whether the platform can accommodate your priorities or offers a one-size-fits-all approach.
5. "What's your approach to shareholder engagement and proxy voting?"
The most sophisticated sustainable investors use their shareholder power to influence corporate behavior. Ask whether the platform discloses how it votes on ESG issues.
Implementation Strategy: Building Your Sustainable Portfolio
Based on the current landscape, here's a practical approach to getting started with sustainable robo-advising:
For Beginners: Start with Tier 2 Platforms
Platforms like Wealthsimple or Betterment offer the best balance of accessibility, credible sustainability, and reasonable fees. They provide a solid foundation that you can build upon as your knowledge and portfolio grow.
For Committed Impact Investors: Consider a Multi-Platform Approach
Given that no single platform excels in all aspects of sustainable investing, some investors use multiple services—perhaps a mainstream robo-advisor for core holdings and a specialized impact platform for specific themes.
For Larger Portfolios: Leverage Human Guidance
Platforms like Justwealth that offer access to human advisors can be particularly valuable for larger portfolios where you want to ensure your specific values are properly reflected in your investment strategy.
The Future of Sustainable Robo-Advising
The sustainable robo-advisor landscape is evolving rapidly. We expect to see several key developments in the coming years:
Deeper Customization: More platforms will likely offer values assessments and customizable sustainable portfolios that reflect individual priorities rather than one-size-fits-all approaches.
Better Impact Reporting: As investor demand grows, platforms will need to provide more transparent and frequent reporting on the actual impact of sustainable portfolios.
Comprehensive Portfolio Sustainability: The current gap between equity and fixed income sustainability will likely close as more sustainable bond ETFs become available and platforms integrate them into portfolio construction.
Taking the First Step Toward Authentic Sustainable Investing
Maya ultimately found a platform that matched her values after doing the research we've outlined here. "I learned that sustainable investing isn't about finding perfection," she reflected. "It's about finding the option that best aligns with your values while being transparent about its limitations."
Your journey starts with acknowledging that "sustainable" means different things to different platforms. By using the three-tier framework and asking the critical questions we've outlined, you can move beyond marketing claims to find a robo-advisor that delivers both competitive returns and genuine alignment with your values.
The most sustainable portfolio isn't necessarily the one with the greenest marketing—it's the one you'll stick with through market cycles because it reflects what matters to you while delivering the financial security you need for your future.
