Key Insights
  • Climate change is increasingly a major concern for global communities, companies, our clients, and our investment teams.
  • The focus on risk mitigation for business activities is intensifying as regulatory efforts on climate are pushed further into the spotlight.
  • As legislative initiatives start to directly impact financial performance, we believe the differentiation between winners and losers will become more apparent.

The impact of climate change presents a systemic investment risk, making the importance of an investment’s environmental footprint more critical than ever before. The world has already experienced a rise of around 1°C in global temperatures over the preindustrial period and has started seeing the impacts of climate change in the form of extraordinary weather events, shrinking glaciers, and changing rainfall patterns.

To be successful in limiting the adverse impacts of climate change, a fundamental shift is needed in the relationship between the economy and the environment. While financial markets are well positioned to play a leading role, ultimately they will only be effective if climate change regulation is in place. However, when it comes to climate change, a mismatch exists between policy and science. Over the past year, we have seen strong momentum to close that gap—a trend we expect to continue as we lead up to the 26th United Nations Climate Change Conference (COP26) in Glasgow in November.

Increasing Momentum for Action on Carbon Emissions

Net zero carbon emissions targets (net zero targets) have been established by 61% of countries, 9% of states and regions in the largest emitting countries, and 13% of cities with a population of over half a million. In aggregate, they account for just over 60% of the world’s carbon emissions.1 A focus of COP26 will be securing greater adoption of net zero targets—more countries have signaled that they will make announcements in the lead‑up to the conference.

"A focus of COP26 will be securing greater adoption of net zero targets..."

Except for a handful of countries that were already advanced in implementing their climate agenda, direct legislation to underpin net zero targets is largely absent. While we remain in the early stages in terms of implementation, it appears that the urgency of the situation is increasingly understood. Simply put, the odds of meaningful climate regulation coming into force is very high.

Carbon dioxide (CO2) makes up about three‑quarters of greenhouse gas emissions and is one of the more readily available environmental statistics. As such, it receives the most attention when it comes to climate change analysis. However, staying within a global temperature rise of 1.5°C will require mitigating more than just CO2. In addition to regulation focused on power generation, energy efficiency, and transportation, the task will require comprehensive regulation to mitigate methane (CH4), nitrous oxide (N2O), and fluorinated gases, as well as more sustainable land use and enhancement of carbon sinks.

"...most estimates indicate that the world’s current climate change commitments put us on a path to 2.7°–3.0°C of global warming."

To date, most of the world’s climate regulation has focused on carbon—mostly within the power sector—but that is changing. To put the potential impact of forthcoming regulation into perspective, most estimates indicate that the world’s current climate change commitments put us on a path to 2.7°–3.0°C of global warming. This is based on climate commitments made through the nationally determined contributions (NDCs) submitted by signatories of the Paris Agreement in 2015. Using a statistically based probabilistic framework, the probability of staying below 2°C warming is only 5% assuming a continuation of current trends.2 If all countries were to meet their NDCs, it rises to 26%.2 These low probabilities underpin the importance for net zero commitments.

How Climate Change Affects Company Financial Performance

While markets have anticipated some climate legislation coming into force, namely in select sectors directly impacted by energy transition, we do not see widespread evidence of dislocation in valuations across the broader economy. As new rules come into effect around the world, we expect that performance around climate issues will become increasingly more important to investment performance. Interestingly, we see a bifurcation in corporate approaches to climate change across all sectors of the economy.

As legislative initiatives start to directly impact financial performance, we believe the differentiation between winners and losers will become evident (and potentially quite quickly). Of course, regulation is not the only factor moving the needle on how issuers are responding to climate change. Other important factors are innovation and consumer preferences.

On the innovation front, new advances have driven down costs in renewable power, which has sped up deployment of renewable capacity. The International Renewable Energy Agency estimates that the 3.2 terawatts implied in current NDC power targets for 2030 should be met as soon as 2022. On the consumer preferences front, we see companies adding environmental labeling to products as well as increasing demand for more sustainable products such as meat alternatives.

Evaluating Climate Change in Investments

At T. Rowe Price, we systematically evaluate climate change factors for individual securities and portfolios with our proprietary Responsible Investing Indicator Model (RIIM). RIIM analysis provides two key benefits for our analysts and portfolio managers. First, RIIM proactively searches for environmental indicators and controversies on companies and sovereign issuers—this is an important feature as environmental data are not required disclosure nor are they standardized like financial data. Second, RIIM provides a framework for evaluating environmental factors—in essence it creates a common language for our analysts and portfolio managers to discuss how an investment is performing on environmental factors as well as compare securities within the investment universe.

Our evaluation of climate change factors focuses on energy transition and physical risk, but we also believe that an issuer’s environmental footprint and track record are important indicators of how they may perform in a tightening regulatory environment.

With our RIIM assessment, we consider our investments’ environmental characteristics holistically—key areas of focus include:

  • Energy transition
  • Physical risk
  • Biodiversity impact
  • Circular economy contribution
  • Land use
  • Water use
  • Track record on environment
  • Accountability and transparency for environmental, social, and governance (including climate change)

Another critical element of our climate change‑related analysis occurs through engagements. The most common topics of our environmentally focused engagements in 2020 were disclosure, greenhouse gas emissions, product sustainability, and general environmental management. In relation to disclosure, we continue to advocate for investee companies to report using Sustainability Accounting Standards Board and Task Force on Climate‑Related Financial Disclosures frameworks. In 2020, we also put more emphasis on the importance of reporting scope 1–3 greenhouse gas emissions.3

We work with an imperfect data set when it comes to environmental analysis. This is partly a problem of limited disclosure and lack of universal reporting standards, but it is partly because some environmentally oriented factors are qualitative in nature (i.e., controversies, targets). Issues of disclosure and standardization are gradually being resolved and new sustainable finance regulations will accelerate what had been a largely voluntary trend from corporates, but we still have a long way to go. For example, carbon emissions is one of the most widely available statistics, but disclosure levels for scope 1–2 emissions cover less than half our investible universe and disclosure for scope 3 emissions is even lower.

Disclosure on Carbon Emissions Data Is Often Limited

We purchase a data set from Sustainalytics that provides carbon emissions and intensity for a universe of more than 11,000 companies, of which nearly 75% of the companies have estimated data. As illustrated in Figure 2, for some indexes, upward of three‑quarters are covered with reported data; however, other indexes are almost entirely reliant on estimated data. While a reliance on estimated data can sound disconcerting to some investors, it has utility because it helps us understand the order of magnitude of carbon emissions for our portfolios versus their benchmarks. However, we do have to be cognizant of the data quality when considering it in our investment decisions.

Climate change is increasingly a major concern for global communities, companies, our clients, and our investment teams. The focus on how companies are working to mitigate the risks to their activities is only set to intensify, and COP26 and regulatory efforts will bring the issue further into the spotlight.

Information contained herein is based upon sources we consider to be reliable; we do not, however, guarantee its accuracy. Actual future outcomes may differ materially from any estimates or forward‑looking statements made.

Past performance is not a reliable indicator of future performance. All investments are subject to market risk, including the possible loss of principal. International investments can be riskier than U.S. investments due to the adverse effects of currency exchange rates, differences in market structure and liquidity, as well as specific country, regional, and economic developments. The risks of international investing are heightened for investments in emerging market and frontier market countries. Emerging and frontier market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed market countries. Fixed income securities are subject to credit risk, liquidity risk, call risk, and interest‑rate risk. As interest rates rise, bond prices generally fall. Investments in high‑yield bonds involve greater risk of price volatility, illiquidity, and default than higher‑rated debt securities. Impact investing or ESG strategies may not succeed in generating a positive environmental and/or social impact. There is no assurance that any investment objective will be achieved.
