GMO Horizons


The GMO Horizons Strategy is a global strategy reflecting the view that the world economy is transitioning to a lower carbon future, and that this process will create opportunities for investors to generate excess returns. The Strategy seeks to capture these opportunities and mitigate related risks through significant exposure to impactful climate solutions and reduced total emissions intensity (direct and indirect), while controlling for exposure to Environmental, Social, and Governance (ESG) risks.

The GMO Horizons Strategy is a fully systematic and diversified solution that provides:

  • High levels of exposure to companies where revenue is derived from selling green products and services
  • Materially lower total emissions than the benchmark as measured using scope 1 emissions and GMO’s proprietary Indirect Emissions model, which estimates the indirect emissions embodied in end-to-end company value chains
  • ESG risk mitigation via better ESG characteristics than the benchmark
