In "21st Century Investing," Burckart and Lydenberg revolutionize finance with "system-level investing" - a paradigm endorsed by Oxford's Robert Eccles as "the future direction of investing." What if sustainable profits actually require fixing the broken systems they depend on?
William Burckart and Steve Lydenberg, authors of 21st Century Investing: Redirecting Financial Strategies to Drive Systems Change, are pioneering voices in sustainable finance and systemic risk management.
Burckart is the CEO of The Investment Integration Project (TIIP) and an Adjunct Professor at Columbia University’s School of International and Public Affairs. He combines academic rigor with practical insights from advising institutions on ESG integration. Lydenberg is a Partner at Domini Impact Investments and co-creator of the groundbreaking Domini 400 Social Index. He brings five decades of expertise in corporate accountability and impact measurement. Their work at TIIP has shaped strategies for institutional investors seeking to align portfolios with societal resilience.
The book distills their shared vision for transitioning from conventional to system-level investing, emphasizing environmental stability and equitable growth. Burckart’s Nasdaq column on LGBTQ+ investment inclusion and Lydenberg’s foundational research at KLD Analytics further underscore their authority.
Praised by leaders at CalSTRS and Oxford Saïd Business School, 21st Century Investing has become a critical resource for funds and academics navigating 21st-century financial challenges. Published by Berrett-Koehler in 2021, it bridges Wall Street practices with global sustainability goals.
21st Century Investing advocates for a system-level approach to finance, urging investors to address interconnected global challenges like climate change, income inequality, and social inequities. Co-authored by William Burckart, it redefines traditional ESG and impact investing by emphasizing strategies that tackle root causes of systemic risks rather than surface-level symptoms. The book provides frameworks for aligning portfolios with long-term societal and environmental resilience.
This book is essential for institutional investors, asset managers, and financial professionals seeking to integrate systemic risk management into their strategies. It also benefits policymakers, academics, and sustainability advocates interested in reshaping finance to address global crises. Burckart’s insights are particularly relevant for those prioritizing long-term, interdisciplinary solutions over short-term gains.
Yes—the book offers actionable frameworks for addressing systemic risks like climate change and social inequities, making it critical for investors navigating 21st-century challenges. Burckart combines academic rigor with real-world examples, such as case studies on pension funds and endowments adopting system-level strategies. Its focus on measurable impact and collaborative investing sets it apart from conventional ESG guides.
System-level investing involves targeting the root causes of global crises—like structural racism or environmental degradation—through financial strategies that reshape economic and social systems. Burckart argues this approach goes beyond ESG by requiring investors to assess interdependencies (e.g., how supply chains affect climate resilience) and collaborate across sectors. Examples include redirecting capital toward regenerative agriculture or equitable workforce development.
Unlike traditional ESG, which focuses on mitigating risks within existing systems, Burckart’s approach seeks to transform flawed systems entirely. The book critiques ESG’s limitations in addressing systemic inequities and advocates for metrics that measure portfolio alignment with global sustainability goals (e.g., UN SDGs). It also emphasizes investor collaboration to amplify systemic impact, such as joint advocacy for climate policy reforms.
These tools help investors shift from siloed strategies to holistic, cross-sector solutions.
The book recommends investing in renewable energy infrastructure while simultaneously lobbying for carbon pricing policies and divesting from fossil fuel-linked assets. Burckart highlights case studies like pension funds supporting green tech R&D and insurance firms integrating climate resilience into underwriting criteria. Key steps include analyzing portfolio exposure to climate feedback loops and aligning with science-based transition pathways.
Burckart critiques short-termism, fragmented risk assessments, and overreliance on ESG scoring systems that ignore systemic interdependencies. He argues conventional portfolios often exacerbate inequality and environmental degradation by prioritizing narrow financial returns over societal health. The book also challenges the notion that shareholder value maximization aligns with public good, advocating for stakeholder-centric models instead.
Drawing on 20+ years in impact finance, Burckart’s roles as CEO of The Investment Integration Project (TIIP) and Columbia University professor inform the book’s blend of academic and practical insights. His work with institutional investors, like guiding pension funds on systemic risk integration, grounds the strategies in real-world applicability. LGBTQ+ advocacy via Colorful Capital also underscores his focus on equitable systems.
Amid escalating climate disasters and AI-driven labor disruptions, Burckart’s system-level approach provides a roadmap for stabilizing economies. The book’s emphasis on pandemic preparedness, equitable tech adoption, and resilient supply chains aligns with current crises. Updated case studies in the 2024 edition reflect lessons from recent market shocks, reinforcing its urgency for investors.
While similar to John Elkington’s Green Swans and Mariana Mazzucato’s Mission Economy, Burckart’s work distinctively focuses on actionable investor collaboration. For technical guidance, paired reads include The Impact Imperative (impact metrics) and Capitalism at Risk (systemic risk case studies). However, 21st Century Investing remains unique in bridging finance theory with institutional implementation frameworks.
The book advocates for “equity-aware” investing, such as funding minority-led businesses and supporting policies like living wage mandates. Burckart emphasizes metrics tracking racial wealth gap reductions and gender parity in portfolio companies. Case studies include affordable housing bonds with tenant equity stakes and VC funds targeting underrepresented founders.

What if your investment strategy is actively undermining the very systems upon which your returns depend? This provocative question lies at the heart of 21st-century investing. As climate change threatens economic stability and inequality mirrors conditions that preceded major historical conflicts, conventional approaches focused solely on portfolio risk management have become dangerously inadequate. The financial industry's enormous scale-global wealth exceeding $360 trillion-means investors now wield unprecedented influence over fundamental systems. This isn't just about ethics-it's about financial survival in an interconnected world where system collapse threatens everyone's returns.
Modern portfolio theory revolutionized finance by focusing on portfolio-level risk rather than avoiding individual risky securities. However, the 2008 financial crisis exposed its flawed assumption that investors cannot influence systematic market risks. System-level investing transcends both conventional and sustainable approaches. Conventional investors focus solely on financial returns, sustainable investors add social considerations, while system-level investors recognize their power to support essential interconnected systems: healthcare, food security, employment, financial markets, climate stability, and natural resources. Climate change responses illustrate this evolution: Conventional investors see opportunities in Arctic drilling or refugee barriers. Sustainable investors maintain "clean" portfolios through fossil fuel divestment. System-level investors take a holistic approach - building alternative-vision portfolios while advocating for disclosure requirements, joining initiatives like Climate Action 100+, creating climate-friendly markets, and supporting regulations. This approach is financial pragmatism, not idealism. With over 90% of returns coming from overall market performance rather than stock selection, strengthening underlying systems enhances returns for all.
Not every social issue requires a system-level approach. Four criteria determine which challenges do: consensus (broad agreement on importance), relevance (substantial impact on financial performance), effectiveness (investor ability to influence outcomes), and uncertainty (risks conventional tools can't address). Fresh water exemplifies these criteria. With 1.2 billion people in water-scarce regions, water is a UN-recognized human right. It impacts economic development across industries, can be influenced through infrastructure investments, and faces uncertainties like glacier retreat and aquifer depletion affecting billions dependent on major river systems. Income inequality similarly qualifies. IMF research shows that when a country's wealthiest 20% increase their income share by 1%, GDP growth falls by 0.08% over five years, while increases for the poorest 20% boost growth by 0.38% - making inequality both a social concern and an economic threat to returns.
System-level investors strategically deploy different asset classes for specific impacts. Public equities enable influence over large corporations through disclosure requirements and shareholder engagement, exemplified by CalSTRS's $2.5 billion Low-Carbon Index reducing emissions by up to 93%. Private equity offers direct ownership without public disclosure constraints. The Caisse de depot et placement du Quebec leverages this to boost economic growth where beneficiaries live, investing in Montreal's infrastructure and creating a $250 million Canadian AI fund. Venture capital funds disruptive business models addressing systemic risks or opportunities. CalSTRS has directed $691 million to clean energy private equity and $505 million to renewable power assets. Bonds finance essential public goods like affordable housing and healthcare. The green bond market has grown to nearly $1 trillion, with firms like Bank of America establishing guiding principles. Real estate and infrastructure investments shape communities, as shown by Prudential Financial's $1.1 billion Newark initiative creating affordable housing and supporting local businesses. This approach targets asset classes to key leverage points that enable positive systemic outcomes - expanding investment opportunities while strengthening overall system health.
System-level investors adapt familiar investment tools for broader impact. Investment beliefs statements now explicitly address systemic risks-CalPERS mentions "climate change," while Washington State Investment Board acknowledges being "subject to complex and systemic global risks." Security selection now extends beyond ESG integration to setting industry-wide standards. Many investors exclude entire fossil fuel industries rather than specific companies, while others create concentrated investment programs targeting systematic change, like Quebec's Caisse with its $3.3 billion in local investments supporting regional growth and renewable energy. Corporate engagement has evolved from individual company discussions to system-wide influence. Hermes Investment Management confronted construction companies on human rights in Qatar-resulting in formal worker protection agreements-and developed tools enabling managers to form holistic views of climate risks across portfolios. Manager selection now requires demonstrating policies with systemic implications, such as joining industry organizations advocating for system-level considerations or showing documented impact records. Aviva Investors maintains a "buy list" of managers passing its ESG criteria and surveys asset managers to enhance industry standards. For water issues, these tools might include adjusting investment beliefs to specify water's material impact across asset classes, instructing managers to include water risks in valuations, requiring property managers to monitor water usage, and incorporating water expertise in manager selection.
Forward-looking investors are developing techniques for system-level challenges through field building, investment enhancement, and opportunity generation. Field-building techniques pool resources for collective action. KL Felicitas Foundation demonstrates this by developing entrepreneur incubators, creating intermediaries like Sonen Capital, and establishing Toniic - a global network of 400+ members managing $4.5 billion in impact investments. Investment-enhancement techniques strengthen systems through traditional activities. Norway's sovereign wealth fund incorporates international standards and divests from harmful industries. Dutch pension fund PGGM allocates billions to impact portfolios addressing climate change, food security, and healthcare, with $17 billion in sustainable solutions. New Zealand Superannuation exemplifies a comprehensive climate strategy by transitioning to low-carbon investments, monitoring managers, investing in alternative energy, sponsoring research, and engaging corporations and other institutional investors. Imagine if every major investor adopted these techniques - how quickly could we solve pressing challenges? What systemic risks in your portfolio could become opportunities through collaborative action?
The world faces unprecedented global risks - from melting ice caps and species extinction to widening inequities and fragile democracies. COVID-19 exposed our unpreparedness for systemic challenges. Yet investors now wield enormous influence, with the top 500 institutional investors controlling over $100 trillion - enough to reshape global systems. Six steps can help investors manage these interconnected risks: 1. Set goals acknowledging that investments affect systemic challenges, recognizing impacts on climate, biodiversity, and social equity. 2. Decide where to focus using four criteria: consensus, relevance, effectiveness, and uncertainty. Climate change exemplifies a priority meeting all criteria. 3. Allocate assets strategically, understanding each asset class's social and environmental purpose - venture capital driving clean technology innovation, green bonds funding environmental projects. 4. Apply investment tools by extending investment beliefs, voting proxies for systemic influence, incorporating issue-specific criteria, and developing ESG frameworks. 5. Leverage advanced techniques through peer collaboration, supporting regulations, aligning stakeholder interests, and creating solution-oriented markets. 6. Evaluate results beyond quarterly reports by assessing managers' goals, actions, and contributions to positive systemic change. A new capitalism is emerging - driven by information flows, data science, and understanding of systemic risks and opportunities. This evolution equips our financial system to generate the just and sustainable economy our planet needs. The question isn't whether you can afford to adopt system-level investing - it's whether you can afford not to. As systemic risks multiply, business as usual threatens both investment returns and planetary wellbeing.
