94% of investors believe corporate reporting on sustainability performance contains unsupported claims: PwC 2023 Global Investor Survey

15 November, 2023

  • Three-quarters of investors say sustainability is important to their investment decisions, while more than half (57%) back greater clarity and consistency in sustainability reporting
  • 61% say faster adoption of AI is “very” or “extremely” important
  • Macroeconomic and inflationary concerns fall from 2022 highs, as concern about climate change rises from 22% to 32%, putting climate on par with cyber risks

LONDON, 15 November 2023 More than nine in ten investors (94%) believe corporate reporting on sustainability performance contains unsupported claims, according to PwC’s 2023 Global Investor Survey, launched today.

The survey – now in its third consecutive year – queried 345 investors and analysts across geographies, assets classes, and investment approaches for insights into the factors that most affect the companies they invest in and cover.

The survey finds that while macroeconomic and inflationary concerns are still top-of mind, they have eased from 2022’s highs. Notably this year, climate risks have risen considerably, putting it on par with cyber risk – at 32%.

All the while, the survey paints a picture of an investment landscape driven by technological transformation: 59% identified technological change as the most likely factor to influence how companies create value over the next three years. In particular, 61% say faster adoption of AI is “very” or “extremely important”.

Sustainability also continues to remain pivotal to investors: 75% say that how a company manages sustainability related risks and opportunities is an important factor in their investment decisions, although this is down 4% on last year. 

“We are moving from a period of awareness raising around the importance of climate and technological change to a time where investors are increasingly asking specific and tough questions about how companies are addressing those issues in their strategy, how they assess risk and opportunity and what is truly material for them. In this context, corporate reporting needs to continue to evolve so it provides reliable, consistent and comparable information investors – and other stakeholders – can rely on.”

Investors look to stronger reporting standards amid greenwashing concerns

Investors this year highlighted a strong undercurrent of doubt around the reliability of sustainability reporting and information that they use, often referred to as “greenwashing”. 94% of investors believe corporate reporting on sustainability performance contains some level of unsupported claims (up from 87% in 2022), including 15% who think they are there to a “very large extent”. The proportion who said unsupported claims are present to a moderate or greater extent is up one percentage point on last year at 79%.

These perceptions of greenwashing may explain why investors are looking to regulators and standard setters to create clarity and consistency in companies’ reporting. 57% of investors said that if companies meet the upcoming regulations and standards (including CSRD, the SEC proposed climate disclosure rules in the US, and ISSB standards), it will meet their information needs for decision-making to a “large” or “very large extent”. Furthermore, 85% say that reasonable assurance (akin to audit of financial statements) would give them confidence in sustainability reporting to a “moderate”, “large”, or “very large extent”.

The focus of investors on meeting the cost of ESG commitments has also risen, with 76% finding this information important or very important. Investors also want information on a company’s impact on society or the environment, and of those, 75% agree that companies should disclose the monetary value of their impact on the environment or society, up from 66% in 2022.

Investors favour accelerated AI adoption, despite risks 

This year’s survey findings show investors view the accelerated adoption of artificial intelligence (AI) as critical to value creation, while recognising the importance of managing risks. 61% of investors say faster adoption is “very”, or “extremely important”. Including responses noting “moderately important”, this jumps to 85%. Investors identified technological change (59%) as the factor most likely to influence how companies create value over the next three years. Furthermore, investors ranked innovation and emerging technologies (including AI, the metaverse, and blockchain) among their top five priorities when evaluating companies. Nonetheless, 86% see AI presenting considerable risk from a ”moderate” to “very large extent” when it comes to data security and privacy; insufficient governance and controls (84%), misinformation (83%); and bias and discrimination (72%). 

“We are seeing significant steps towards more consistent reporting from companies around climate change, however there is a need for improvement. All the while, investors are calling for greater engagement around how companies manage the opportunities and risks of new technologies, particularly generative AI, as new technologies increasingly drive business transformation and investment.”
