In brief

  • New analysis shows listed companies are responsible for 40% of greenhouse gas emissions, much higher than previous estimates
  • Research highlights the importance and influence of investors in delivering a net zero world

London, 11th October 2021

Listed companies are responsible for 40% of all climate-warming emissions, shows a first-of-its kind analysis by Generation Investment Management, the sustainable investment management firm. In its Insights 6: Listed Company Emissions report, published today, Generation reveals that all previous estimates underplay the true impact that listed companies have on climate-warming emissions.

Generation’s research combines a number of calculations to give a clearer picture of the greenhouse gas emissions accountable to listed companies. In particular, the research looks beyond the company boundary, taking into account Scope 1, 2 and some types of Scope 3 emissions like supply chain impact1. The research also seeks to eliminate the problem of double counting emissions.

Miguel Nogales, co-Chief Investment Officer of Generation Investment Management, said:

“Listed companies are hiding in plain sight when it comes to the climate crisis. Far from being minor players, our analysis shows they are responsible for around 40% of all climate-warming emissions. Of course, this also means that the influence and leverage of the investment community has been underestimated. As COP26 approaches, our research highlights the importance of capital allocation choices and meaningful portfolio engagement if we are to be successful in delivering a net zero world by 2050.”

“Given their outsized resources and focus on developed markets, listed companies will need to deliver the lion’s share of private sector emissions reductions in the next few years. If the world needs to get to net zero by 2050, the ambition for public companies overall should be 2040 at the latest - and they must focus on decarbonisation in the near term.”

Research methodology

Most previous estimates focus on direct emissions only (known as Scope 1 emissions) and estimate listed companies’ emissions at around 20% of the total. Generation’s analysis, which incorporates listed companies’ value chain GHG emissions, estimates almost double the Scope 1 results, based on CDP data. Similarly, it is more than double the Scope 1-only calculation published recently by MSCI.2

For example, the Generation analysis includes oil produced by listed global oil majors that is consumed by households and smaller non-listed enterprises, as well as the oil consumed in vehicles manufactured by listed companies. The problem of double counting is accounted for in the research.

The analysis also considers emissions from food production and changes in land use which are largely absent from Scope 1 estimates, because most food is produced by smallholder farmers, larger independent farmers and cooperatives or by privately owned companies.

Even with these additional factors included, Generation’s estimates are likely to be conservative. For example, the analysis excluded emissions where double counting was too difficult to address and where sufficient, reliable data was not available from public sources. Future research will expand the methodology to cover other ways listed companies contribute to global GHG emissions.
