The impact investment is to allocate resources to solutions that improve lives and generate profit. ESG criteria are a framework for reporting risks and performance environmental, social and governance of any organization. Impact investing is an activity that finances transformations, while ESG is a tool for visibility of exposure to problems that may affect a business, including impact investments.

What is impact investing?

Impact investing is about investing to change lives while generating financial returns. The GIIN defines it as placing capital with the intention of achieving positive, measurable effects, along with competitive profitability.(thegiin.org) It was born at the intersection between alternative finance and social entrepreneurship.

Characteristics

  • Intentionality: social impact is pursued from the design of an intervention.
  • Rigorous measurement: to generate attributable evidence of social transformation with frameworks such as IRIS+ that standardize indicators.
  • Multiple assets: using financial vehicles and instruments such as debt, equity, thematic bonds and/or blended finance.

Brief example: a fund that finances decent and affordable housing in a municipality that has high credit rates and levels of overcrowding.

What are Environmental, Social and Governance (ESG/ESG) criteria?

ESG criteria are a reporting and measurement framework that analyzes how a company manages its Environmental footprint, its Social impact and the quality of its Governance. They do not seek, on their own, to produce a specific positive change; its focus is assessing non-financial risks and opportunities that could influence long-term economic value.

  • Environmental (E): CO₂ emissions, water use, waste, climate risk, among others.
  • Social (S): labor rights, diversity, product safety, relationship with the community, among others.
  • Governance (G): corporate ethics, board composition, fiscal transparency, among others.

There is no single list of ESG indicators. Unlike the UN SDGs, each company can choose metrics relevant to its organization. However, several organizations have created standards to facilitate comparison:

  • GRI (Global Reporting Initiative) for sustainability reports.
  • SASB (now part of ISSB) for sector metrics.
  • TCFD for climate risk disclosure.
  • ISO 26000 as a voluntary guide to social responsibility.

Companies combine these guides or create their own KPIs. The final result is reflected in ESG ratings issued by agencies such as MSCI or Sustainalytics, which assign a risk rating. A high rating indicates less exposure or better management of ESG issues, not necessarily a measurable positive impact.

Example: a shoe company can apply ESG criteria to avoid buying from suppliers that pollute rivers or violate labor rights, even if its business objective does not directly improve social or environmental issues.

Fundamental Similarities

Although they come from different sectors, impact investing and ESG share a key idea: using capital to improve society while achieving financial results. Both bring the financial world closer to sustainability, and offer different tools to make more responsible decisions.

In practice they share three main principles:

  • Return with responsibility. They pursue competitive returns without sacrificing ethics or care for the planet.
  • Data and transparency. They require verifiable metrics, audits and public reports that allow results to be compared and improved over time.
  • Private capital as an engine of change. They recognize that the market, well directed, can mobilize resources that states or philanthropy cannot achieve.

In short, both models answer the same question: how to multiply financial value while protecting - or improving - the lives of people and ecosystems?

Key differences

Sharing purpose does not mean operating the same. The two approaches are distinguished by their starting point, the tools they use and the depth with which they intervene in reality.

Impact investment is based on a thesis of change: it detects a specific problem - decent housing, education, clean energy - and directs capital to solutions capable of solving it. Profitability is built from that value created.

ESG criteria, on the other hand, are born as a risk lens: they evaluate how the environmental, social and governance performance of any company can affect its future cash flow, even if the company does not have an explicit impact mission.

Although they dialogue, their roots generate important nuances:

  • Starting point
    • Impact investment: seeks to solve a specific social problem; The central actor is the thematic investor.
    • ESG / ESG: focuses on portfolio risk management; The central actor is the asset manager or issuer.
  • Deployment Tools
    • impact investment: funds, bonds and blended finance schemes.
    • ESG / ESG: ratings, sustainability policies and exclusion criteria.
  • Measurement
    • Impact investment: changes in people's lives and effects on the environment.
    • ESG / ESG: compliance with standards and regulations.
  • Horizon
    • Impact inversion: variable according to investment thesis, with the possibility of defined outputs.
    • ESG / ESG: continuous and long-term, linked to permanence in the management strategy.

In other words, impact investing funds the solution, while ESG monitors the footprint any business leaves when operating. That is why they usually coexist: first the risk is filtered with ESG criteria and then a part of the capital is allocated to impact vehicles that deepen the transformation.

That is to say: impact investment finances solutions; ESG calibrates risks.

How do they complement each other?

Impact investing and ESG criteria can operate separately, but when combined, a more complete vision is obtained: solutions that generate positive impact are identified and financed, while risks that may compromise their sustainability over time are prevented or mitigated.

One way to understand this complementarity is to see it as a logical sequence:

  • First, ESG criteria are used as a basis of analysis to avoid supporting organizations that may cause harm or be exposed to serious ethical, social or environmental risks. It's not about changing the world with this first step, but rather making sure you don't fund harmful or unsustainable practices.
  • Then, on that basis, impact investing goes one step further: it not only avoids the negative, but seeks the positive. Here comes an impact thesis, which proposes a specific transformation - such as improving education, generating decent employment or expanding access to clean energy - and an investment is structured with that clear purpose.
  • During execution, both tools can coexist: ESG indicators allow monitoring the general behavior of the company or project on sensitive issues such as governance, emissions or relationship with communities, while impact indicators directly measure the changes generated in people's lives or in the environment.
  • At the end of the cycle, having both perspectives (generated impact and ESG performance) can facilitate the attraction of new investors, especially those who seek profitability with responsibility, but also rigor and evidence.

This articulation does not always occur automatically. It requires intention, design and alignment between the impact purpose and the risk assessment structure. But when achieved, it strengthens the credibility of the investment and expands its scaling potential.

Examples

  • Bancolombia-IDB Sustainability Bonus 2022: tied the coupon to two KPIs - bankingization and CO₂ reduction - mixing impact goals with ESG verification.
  • Laboratoria (Latam): ed-tech that trains women in programming. Use impact capital for expansion and report your ESG (workplace inclusion, diversity, governance) footprint to traditional funds.
  • CG Octopus Energy I Sustainable Growth Fund ('Astris'): applies ESG exclusions to avoid polluting energy and supports clean initiatives.

Why do they add more together?

  • Risk-adjusted performance: ESG reduces negative surprises; Impact investing opens up high-growth niches (green energy, digital health and carbon credits).
  • Access to diverse capital: allows attracting both institutional investors - who demand ESG - and thematic investment funds - which demand impact.
  • Regulatory and social trust: regulators value risk management; Communities value the concrete solution.

Supplementary summary

  • Impact investing generates opportunities that change lives.
  • ESG mitigates risks that can erode profitability.
  • Together they create resilient and purposeful portfolios.
