The MSCI Net-Zero Tracker
A quarterly gauge of progress by the world's public companies toward curbing climate risk.
The MSCI Net-Zero Tracker indicates the collective progress of publicly listed companies in the MSCI ACWI Investable Market Index (IMI)1 (which covers 9,300 listed companies, representing 99% of the global equity universe) in keeping global warming well below 2°C. It also highlights the largest listed companies with improved climate disclosures, as well as those that lag.
The MSCI Net-Zero Tracker offers investors, companies, financial intermediaries and policymakers an objective gauge of the contribution by the world's public companies to total carbon emissions and their progress toward a net-zero economy.
Cumulative Emissions of Publicly-Listed Companies in 2021
Companies in the MSCI ACWI Investable Market Index (IMI) are projected to emit an estimated 11.1 billion tons (gigatons) of direct (Scope 1) greenhouse gases annually, putting them on a trajectory to exceed their carbon budgets for keeping global temperature rise below 1.5°C as soon as 2026.
Months left to keep warming below 1.5°C
Time remaining until listed companies deplete the emissions budget for keeping global temperature rise below 1.5°C this century.
Months left to keep warming below 2°C
Time remaining until listed companies deplete the emissions budget for keeping global temperature rise below 2°C this century.

 The MSCI ACWI Investable Market Index (IMI) captures large, mid and small cap publicly listed companies across 23 Developed Markets (DM) and 27 Emerging Markets (EM) countries. The index is comprehensive, covering approximately 99% of the global equity investment opportunity set.
We're running out of time to reach net-zero emissions
* The chart above shows annual total Scope 1 emissions of MSCI ACWI IMI constituents (not index weighted) based on companies' reported emission data and MSCI estimates, up to 2020. Emissions for 2020 that companies haven't yet reported and 2021 figures are based solely on MSCI estimates, given a lag in company reporting. The remaining future emissions budget to achieve a 1.5°C and 2°C warming scenario are calculated based on bottom-up estimates (sum of remaining emissions budget of all MSCI ACWI IMI constituents) as of August 31, 2021.
