Environmental Sustainability intro copy

Preventing the worst effects of a warming climate is one of the defining challenges of our lifetime and reminds us how fragile our world is. As a public company that has called upon capital-markets participants to help drive the transition to net-zero, we strive to be transparent in how we seek to reduce our own firm’s carbon footprint.

Our approach is designed to align with the solutions we produce to help investors take climate change into account and make net-zero part of their own investment strategies. We strongly believe that we have a responsibility and commitment to our clients, employees and the communities in which we operate to seek to minimize our impact on the environment and help transition to a net-zero economy in accordance with publicly announced goals. We aim to lead by example.

MSCI is committed to net-zero before 2040

Net Zero Financial Service Providers Alliance

In September 2021, MSCI became a founding member of the Net Zero Financial Service Providers Alliance, which unites leading index providers, credit rating agencies, accounting firms, financial exchanges and other suppliers of market infrastructure that have committed to align their products and services with the goal of global net-zero emissions by 2050.

Science Based Targets initiative (SBTi) verification status

At MSCI, we support science-based targets. We have filed both enhanced near-term (interim) and long-term (net-zero) targets with SBTi for verification. SBTi is a collaboration between CDP, the United Nations Global Compact, World Resources Institute and the World Wide Fund for Nature. Our targets align with a 1.5°C pathway.

Getting to Net Zero

Getting to net-zero

To help meet our ambitious goals, MSCI will prioritize reducing emissions using the levers below.

Source Main levers
Scope 1 &2
  • Reduce electricity consumption in existing offices
  • Manage new office growth towards locations with renewable electricity access
  • Purchase Energy Attribute Certificates (EACs)¹
Scope 3
  • Engage and influence our suppliers to set similar climate goals as ours
  • Manage business travel and encourage virtual meetings
  • Reduce the need for employees to commute to offices

We anticipate that MSCI’s trajectory of carbon reductions will not be fully linear, and our plan will evolve over time to align with the latest science, the emergence of new and greener technologies, and as new data becomes available. As we revise our plan and receive additional stakeholder input, we intend to make our approach transparent by regularly reporting our progress.

Environmental sustainability metrics

Environmental sustainability metrics

  • Greenhouse gas emissions

    We strive to increase disclosures of the greenhouse gas emissions associated with our business operations. In 2020, we expanded the coverage of our emissions to account for all our relevant Scope 3 emissions. In 2022, we received third-party limited assurance for our 2021 greenhouse gas emissions.

  • Energy efficiency

    We continue to implement new ways to use energy more efficiently through climate control setbacks, energy-efficient lighting, motion sensors and other technologies. We prioritize energy efficient selection of buildings with green certifications including Leadership in Energy and Environmental Design (LEED) and Building Research Establishment Environmental Assessment Methodology (BREEAM). In 2021, we purchased Energy Attribution Certificates (EACs) in the locations where energy was consumed to increase our use of renewable electricity. We intend to review annually the potential purchase of EACs to lower our Scope 2 emissions that we otherwise cannot avoid.

    2019 2020 2021
    Energy consumption  
    Percentage of renewable electricity 17% 53% 94%
    Decarbonization plan indicators
    Reduction of Scope 1&2 (market) from 2019 base year -75%
    Reduction of Scope 1&2 (location) from 2019 base year -17%
  • Water usage

    MSCI is committed to responsible water management to conserve usage and prevent pollution. We maintain policies that empower staff to procure renewable, reusable and recyclable products. Due to the nature of our business as a financial services provider, our water consumption is not material as illustrated by the estimated water usage for our seven largest locations, representing 80% of our 2021 headcount.

Supplier engagement

  • We are intensifying efforts to drive down emissions across our supply chain — the source of 72% of our greenhouse gas emissions in 2019, our base year. To help achieve that goal, we have developed a sustainable supplier management program that fully integrates climate considerations into our supplier selection and prioritizes our spend based on the strength of supplier climate commitments.

      We require suppliers to take steps to:
    • minimize their environmental impact
    • implement policies and targets to reduce emissions
    • reach net-zero emissions before 2040
    • disclose energy consumption and emissions
    • report annually on progress towards targets

    MSCI created a dedicated Sustainable Supplier Management team in 2021 to deepen our engagement with suppliers and to understand their decarbonization commitments, climate trajectories, and environmental and social practices. We meet with suppliers regularly to emphasize the importance of targets and our expectations to ensure we reach our net-zero goal.

    See our Supplier Code of Conduct for the values and expectations, including labor, human rights, environmental, legal, and regulatory compliance principles, that we expect our suppliers to uphold. We ask that suppliers acknowledge receipt and review the code.

CDP Climate Change Questionnaire 2021: Grade A-

In 2021, MSCI submitted its response to the CDP questionnaire for the third consecutive year and increased its score from B to A-. The score improvement reflects MSCI’s leadership position on climate including our best practices related to climate governance, business strategy, financial planning, and carbon reduction initiatives. The questionnaire includes key climate-related metrics such as our energy usage and carbon emissions which include details on our scope 1, 2 and all relevant categories of scope 3. MSCI’s 2022 report has been submitted to the CDP, but not yet scored.

Environmental Sustainability footnote

¹An Energy Attribute Certificate (EAC) is official documentation to prove renewable energy consumption. Each EAC offers proof that a specific unit of renewable energy (usually 1 MWh) has been produced from a renewable source and added to the grid. It essentially reflects the "greenness" of the electricity.

²This includes only those suppliers that had SBTi targets or commitments to setting such targets. For 2021, we also included any supplier that is a member of GFANZ as membership requires an implied commitment to set science-based targets.
