Charting the Path to 2030

In this session, Corporate Knights thought leaders reveal which countries and sectors are leading and lagging in the race to net-zero. A panel of leaders from the front lines of the climate movement respond to our findings and  share their insights on the tectonic shifts needed for G20 countries to deliver on 2030 commitments.

Critical Emissions 1/3: Powering net-zero

Decarbonization in the power sector was the greatest source of G20 emissions reductions in 2019. With renewable electricity and grid modernization projected to grow at double digit rates throughout the 2020’s, the power sector is already undergoing rapid transformation. In this panel, we discuss how this critical sector can help close the Say–Do Gap.

Critical Emissions 2/3: Navigating net-zero

Electric vehicle sales have been on a long-term exponential growth curve and have continued to accelerate since 2019. As the internal combustion engine is phased out for passenger and commercial ground transportation, this sector will contribute to a significant new source of electricity demand and is set to undergo significant transformation in the coming years. Join us as we discuss how this critical sector can help close the Say–Do Gap.

Critical Emissions 3/3: Building net-zero

In 2019, the building sector accounted for 8% of total G20 emissions. Fuel consumption in buildings remains a significant contributor to these emissions, and is likely to spur new investments in smart buildings over the coming decade. Join us as we discuss how this critical sector can help close the Say–Do Gap.


EARTH INDEX is the fundamental metric that measures the speed at which countries (by sector) are reducing greenhouse gas (GHG) emissions relative to the speed required to deliver on their commitments.
Its objective is to create real-time global awareness of whether annual GHG emissions are being reduced fast enough to follow through on the long-term targets countries have set. We begin by focusing on G20 countries, which account for about 80% of global GHG emissions.
EARTH INDEX has been developed and refined with the input of many collaborators and stakeholders, including Corporate Knights’ research division, an advisory network of eminent experts in related fields, and ongoing contributions from CEOs of the Global 100 Most Sustainable Corporations in the World.


With the Glasgow Climate Pact, governments came forward for the first time with sufficiently ambitious targets to hold global warming to below 2°C. But when countries state long-term targets without short-term accountability, trust erodes, which undermines the public consensus required to achieve targets. Increased transparency on short-term results enhances accountability and helps build trust.
Progress must be measured in real time so that countries can be held accountable for delivering on their commitments. For this to happen, we need clear and consistent data, broken down in ways that make sense to specialists and non-specialists alike. The key feature of EARTH INDEX is that it recalibrates annually, based on actual emissions progress. Since this will happen on a sector-by-sector basis, it will be crystal clear where the gaps are, both within and between countries.
Current progress in reducing emissions falls short of even the Paris targets; taking the G20 countries together, emissions actually went up in 2019. Bending the GHG emissions curve is an urgent imperative that will take monumental effort from all of us.
While existing climate initiatives assess countries’ policies and pledges in the context of global GHG emissions targets required to meet defined climate goals, EARTH INDEX measures the pace of reported GHG emissions reductions required to meet targets as laid out by countries.
