<strong>CARBON</strong> REDUCTION POTENTIAL:<br />

BENCHMARKING MEDIAN<br />

<strong>CARBON</strong> EFFICIENCY<br />

The <strong>ET</strong> Carbon Rankings are designed to<br />

encourage investors to shift investment to<br />

more carbon-efficient companies, reducing<br />

their own exposure to carbon risk and<br />

rewarding companies that take action<br />

and disclose it. This is intended to drive<br />

decarbonisation across the economy, by<br />

incentivising each company to become more<br />

carbon-efficient.<br />

The <strong>ET</strong> Low Carbon Index Series, which is<br />

based on the <strong>ET</strong> Carbon Rankings, weights<br />

investment towards the 50% of companies<br />

that are less carbon-intensive and away from<br />

the 50% that are more carbon-intensive. Thus,<br />

the Index Series rewards companies that<br />

achieve greater than median carbon efficiency.<br />

In this section, the median carbon-efficiency<br />

is used as a benchmark to get a sense of the<br />

carbon reduction potential associated with<br />

this approach (see Figure 11).<br />

Analysis of just the 363 companies that have<br />

disclosed complete Scope 1 and 2 emissions<br />

in the <strong>ET</strong> Global 800 reveals that in each<br />

sector, if the 50% which are more carbonintensive<br />

were to achieve the median level<br />

of carbon efficiency, it would save 1.4 billion<br />

tonnes of carbon dioxide a year, equivalent<br />

to the emissions of Japan, the world’s third<br />

largest economy. 26<br />

Further analysis reveals that 86% of these<br />

savings – 1.2 billion tonnes of carbon dioxide,<br />

equivalent to twice the emissions of South<br />

Korea – could be made by companies in just<br />

five industries: Electric Utilities; Oil and Gas<br />

Exploration and Production; Construction<br />

Materials; Chemicals; and Real Estate Owners,<br />

Developers and Investment Trusts. 27<br />

This analysis only looks at those companies<br />

that have disclosed complete Scope 1 and 2<br />

emissions, and does not consider the impact<br />

of Scope 3 emissions which typically account<br />

for 75% of companies’ total emissions. It is<br />

safe to assume that far greater savings could<br />

be made if the world’s largest companies took<br />

action to increase their carbon efficiency to<br />

the median level in their sector across the full<br />

range of their direct and value chain emissions.<br />
