Introduction

Markets see the 2024 US presidential election as pivotal to determining the path forward for sustainable investments. The US is the largest international funder of climate change mitigation and adaptation efforts. It is also home to a thriving market of renewable energy and electrification innovation, but the second largest emitter of carbon dioxide in the world as well.

Yet, contrary to emerging consensus, we believe that the party governing from the White House matters less to sustainable investing strategies and performance than overall macro conditions.

It is true that the two political parties sharply diverge in their positions on sustainability, reflecting two different potential paths for US policy. Recent history offers a useful guide: In 2016, President Trump withdrew from the Paris Agreement, and the Environmental Protection Agency rolled back over 100 policies within the first year of his administration. In 2022, under President Biden, Congress narrowly passed the Inflation Reduction Act (IRA), the largest climate-related investment legislation in US history allocating nearly USD 500bn in new spending and tax breaks for initiatives ranging from solar energy production to carbon capture by oil and gas companies, to electrification.

However, although regulatory and legislative actions matter, investor behavior and the performance of sustainable investments have surprised during both administrations.

In this special 2024 ElectionWatch edition of Sustainable Investing Perspectives, we dive into the history along with the policy expectations across energy, renewables, social issues, and SI investments, while discussing the implications for global investors. With eight weeks to go until the November 5 election, much could still change.

Investors should certainly be prepared for potential volatility in these thematic areas, but we recommend they continue to position for the longer-term opportunities tied to sustainability.

What happens with each candidate?

Labor Day weekend in the US marks the unofficial end to the summer. In an election year, this is also the time when the race enters the home stretch. Polls currently suggest that Vice President Harris is slightly better positioned in the race against former President Trump, but this election is still a toss-up with eight weeks remaining until the election on November 5. Of the four potential election outcomes, “Harris with split Congress” and a “Red sweep” are our two most likely scenarios with 40% and 35% probability, respectively (see our scenario analysis for up-to-date probabilities). We focus on these two scenarios when considering the impact of the election on sustainable investing.

In the sections following this summary, we discuss investor implications for each topic.

Climate, environment, renewables

The Inflation Reduction Act (IRA) of 2022, passed along partisan lines, represents the single-largest US investment legislation in clean energy, electrification, and decarbonization. It is also one of the largest global government investment packages in these sectors. This election has been focusing on the preservation of the IRA and determining the Environmental Protection Agency’s (EPA) regulatory direction for environmental standards. As the largest funder of the World Bank, US participation in international agreements is also relevant to global efforts on climate and the environment.

Social issues, diversity, equity and inclusion (DEI) and artificial intelligence (AI)

The question of workforce management and DEI in corporate activity and investment decisions has emerged as a wedge issue in recent years. The Biden administration has embedded diversity-related requirements and incentives across federal activities and supported additional union activity. Policymaking differences in these areas will significantly impact corporate actions on these topics.

Sustainable investing (SI), Environmental, Social, and Governance (ESG) topics

There is a robust debate and divergence between the two parties on the question of whether asset managers can consider sustainability-related factors in investment decisions. The debate is playing out at the federal level through agency rulemaking that could change how easily managers can bring to market SI strategies, as well as whether companies can or should disclose sustainability information to the market.

US voter preferences on climate change drive candidate policies

Three-quarters of voters in the representative sample believe there should be regulation of CO₂ as a pollutant.

The debate on climate-related policy has become a significant wedge issue in US politics over the past few years. Despite this, over 70% of registered voters have consistently expressed belief in climate change since 2016, according to Yale University surveys. Not only do Americans believe in climate change, but nearly three-quarters of voters also support regulating CO₂ as a pollutant.

The partisan divide is stark, with a 40- to 50-point difference on climate-related beliefs between registered voters who self-identify as conservative Republicans and liberal Democrats. This divergence is expected and reflected in campaign rhetoric on both sides. However, what stands out in the data is that over 65% of moderate Republicans and Independent voters do support CO₂ regulation. This data suggests that Vice President Harris is likely to keep her campaign speeches light on the topic of climate, as she has done thus far, assuming tacit support by a significant part of the committed electorate. We don’t believe that fewer mentions of climate mean that a Harris administration would not keep environmental sustainability on its governing agenda. The extent to which they’d be able to make additional meaningful change from the current baseline will depend on the Congress’ composition.

Interestingly, voter polling data indicates a “follow the leader” effect among conservative Republicans, as former President Trump has drawn a distinction on the topic. A record 60% of conservative Republicans supported CO₂ regulation in 2018, halfway through the Trump presidency and following US withdrawal from the Paris Agreement. Support has dropped to a decade low of 42%, with a major drop in 2020. The broader Republican party might see an advantage in preserving environmental, renewable energy and decarbonization-related policies, but the former president’s position will likely dictate policy adoption.

Investment implications

IRA, fossil fuels and clean tech

Despite headlines, we do not expect either of the two most likely scenarios to have a meaningful impact on fossil fuel related companies nor on the electrification and renewable-energy-related companies.

We do not expect the clean energy related incentives in the Inflation Reduction Act to be dismantled as a base case, given that investment in the first two years of the legislation has benefited majority Republican and Democratic districts alike (Figure 2). IRA credits at risk in our “Red sweep” scenario will most likely be those related to offshore wind and clean hydrogen energy production credits. We expect the aggregate impact to be minimal in real terms in these cases, as only a negligible part of US clean energy production is driven by each subsector. Electric vehicle (EV) credits face greater risk in our “Red sweep” scenario due to former President Trump’s critical stance on EVs and the current challenges facing the industry, such as supply chain issues and market competition, which weaken their political appeal.

In our “Harris with split Congress” scenario, we similarly do not expect any additional policy support from the federal government in sectors related to clean tech, although action might continue at the margin with policies such as mandating electrification of federal fleets and decarbonization objectives in federal procurement. We also do not expect a Harris Administration to be more restrictive to the oil and gas sector than the current administration. We expect traditional energy companies to continue some of the policies announced already on methane reduction or carbon-capture-related innovation.

While from a fundamental perspective we see limited impact on renewables and fossil fuels in either election scenario, we expect some headline-related volatility as we get closer to November. Sectors related to themes like the Energy transition and Energy efficiency have experienced significant pullback since the 2021 peak, prior to the war in Ukraine and interest rate hiking cycle. Valuations stand today at a full standard deviation lower than the past five years, implying potential for long-term-oriented investors to reposition in the sector.

The state of ‘sustainable investing’ and ESG, federal and state-level action

While the debate on sustainability unfolds at the federal level, much of the legislative activity has been at the state level in the past two years. As the conversation reached a fever pitch last year, most state legislatures adopted either pro- or anti-ESG legislation. According to Institutional Investor, this year there were 161 anti-ESG bills put forward as of June 2024 at the state level. Of those, only six passed.

The evolution of state-level activity matters to the ability and willingness of investors to adopt SI strategies. We anticipate the debate to intensify again if Harris is elected. We have seen two types of anti-ESG legislation put forward: 1) prohibitions for states to do business with specific entities that boycott industries like fossil fuels or guns, and 2) prohibition of state pension funds from considering sustainability-related factors in investments. The latter category most directly limits the growth potential of sustainable investing strategies and brings additional risks for asset managers focusing on these strategies. It is important to note that even these regulations have so far emphasized the importance of “pecuniary” factors, i.e., consideration of ESG or sustainability if considered financially material.

Conversely, multiple states have adopted pro-ESG stances in a backlash to the backlash, explicitly permitting or even encouraging the integration of sustainability-related factors in investment decisions. This divergence creates a patchwork of regulations that can be challenging for investors to navigate. The “anti-” and “pro-” ESG debate is actively fought at the state level, with a flurry of activity and copycat legislation.

Despite the headlines, the impact of anti-ESG regulations is less significant than it might appear. Over 70% of total assets from state pension plans are concentrated in 15 states, and most of these states have neutral to positive regulations regarding sustainability (Figure 4). Furthermore, more than 90% of US assets under management (AUM) belong to private investors and institutions, corporate retirement plans or federal retirement plans, which cannot be legislated at the state level. The combined value of state-level public pension plans was about USD 6tr in 2023, only about 10% of the USD 60.4tr in AUM.

Although the actual impact ought to be limited, we have seen a shift in terms of messaging from some US-based large asset managers over the last year. In other words, despite what should be a limited impact, we have seen the beginning of a “greenhushing” movement: the opposite of “greenwashing,” this is where managers (and corporates) understate the importance of sustainability in order to not enter controversies on the topic. It’s possible that this trend continues in the coming years, regardless of the outcome at the national election.

What are the implications of each outcome for global investors?

Europe

The re-election of Ursula von der Leyen as president of the European Commission, along with her commitment to the EU Green Deal and a center-right EU Parliament majority, reinforces our view that Europe will maintain its progress on energy transition and broader sustainable development goals in the near term. We anticipate continued implementation of existing climate and sustainability legislation, though the introduction of new laws may be constrained by regulatory fatigue and the current costs of regulatory implementation. Many European countries have introduced legislation or incentives for large institutional investors, such as public pension funds, to invest sustainably. Additionally, the EU and the UK have ramped up their sustainability-related regulatory frameworks, including on fund names, transparency and reporting, as well as definitions on what constitutes a “sustainable investment.”

The US is the largest trading partner for the EU in both exports and imports. Despite the EU’s record high share of renewables (54% as of April) within its grid, the US is a key supplier of fossil fuel and natural gas energy to the EU, a role that has grown since Russia’s invasion of Ukraine in 2022. Moreover, many cleantech and renewable-energy European companies have sought to move operations to the US to benefit from the larger US IRA credits. A more protectionist policy under a “Red sweep” scenario could pose challenges to some of that progress, and to European industrials and utilities companies, as well as European electric vehicle manufacturers. It could also strengthen the US dollar in the short term, affecting green and social bonds, which are predominantly denominated in euros. Finally, it might also put pressure on European NATO members to increase military spending further, potentially conflicting with some investors’ sustainability preferences. A Harris presidency is more likely to maintain the current state of the European-US relationship when it comes to sustainability. Therefore, we think investors should continue to diversify their thematic, regional and currency exposure within sustainable portfolios.

US companies represent a significant portion of assets within European sustainable investing funds, although they are less represented there than in conventional European funds or broader global equity markets. This highlights that European sustainability-focused investors continue to seek opportunities within the US, while also seeking the comfort of the increased sustainability-related transparency within Europe. With USD 2.5tr of AuM as of first half of 2024 (or 83% of global assets, according to Morningstar), Europe has been dominating sustainable equity and fixed income fund flows during the last two US administrations, demonstrating a relative immunity of asset flows to election outcomes.

China

China has been front and center of US foreign policy during the past two administrations, regardless of which party’s leader occupies the White House. Tensions between the superpowers are unlikely to abate, as the hardline positioning reflects bipartisan consensus.

The focus topic is trade, and while recent tariff hikes originated from the first Trump administration, President Biden kept most of these and introduced further hikes. Nonetheless, former President Trump had suggested a blanket 60% tariff on all Chinese goods during his campaign, which the Tax Foundation estimates would boost tax revenues by USD 524bn annually but shrink GDP by at least 0.8% and employment by 684,000 full-time equivalent jobs. Meanwhile, Chinese export controls on critical semiconductor materials have also caused supply chain issues and cost pressures.

Currently, China accounts for 95% of global solar production facilities across the supply chain, 60% of wind, and 70% of EVs, all as of 2022 according to the IEA. Oversupply of finished solar panels due to subsidies and availability of raw materials resulted in a drop of production costs of 42% in 2023 in China. This means that a solar panel is 60% cheaper in China vs. the US, as reported in April by Wood Mackenzie, and an average EV purchased in China is 38% cheaper than the US, according to the World Economic Forum. In our view, tariffs and trade protectionism on transition technologies may slow near-term decarbonization progress and make the effort significantly more costly, even if they mean higher total investments in the area and, potentially, expansion of global ecosystem capabilities in the long term.

We discuss our views on the election outcomes and tariffs in depth in the report ,“The economic and investment implications of higher tariffs.”

US international leadership

Beyond China, the most crucial issue we see is that of the US’s continued leadership as the largest provider of international climate funding (going to areas such as energy efficiency, renewable energy capacity development, etc.), and being the backer of innovative transition solutions and multilateral negotiations. Under President Biden, US climate funding exceeded USD 9.5bn in 2023, from a base of USD 2bn in 2021, in addition to contributions to multilateral development banks that may have further allocations to climate. Going into 2025, international climate funding pledges are due for renewal, and we don’t believe a Trump administration would be likely to extend these commitments. That said, immediate downside risk may take time to transpire as current funding plans can have 3-5 years’ visibility.

US leadership has also been instrumental in shaping multilateral climate action, as well as innovation in this space, such as the USD 20bn Just Energy Transition Partnership agreement for Indonesia, and thus plays a crucial role in multilateral negotiations and progress. While not our base case, think tanks associated with Trump had explored potential withdrawal from the UNFCCC (The UN Framework Convention on Climate Change, the treaty backing the Paris Agreement). This requires a two-thirds Senate majority to pass, which makes it unlikely. US companies’ participation in international collaboration, especially in heavy industry and transportation where output is highly traded and markets are global, also remains critical in driving structural progress. Any policy or regulatory barrier to this continued participation may hinder outcomes.

How much does it all matter?

Performance of sustainable investing strategies historically has not hinged on the US presidency. Just like in other investment areas, we urge investors to stay invested and focused on their strategic investment views.

In sustainable investing, the macroeconomic environment remains a key performance driver, with thematic strategies particularly sensitive to interest rates and other developments. For example, despite limited policy support for renewables and cleantech during the Trump administration, the S&P Global Clean Energy index rallied more than 300% towards the end of Trump’s term, largely due to emergency interest rate cuts at the start of the COVID-19 pandemic. As ten-year yields increased in 2021 and 2022, pressure mounted on the index, which is heavily weighted towards growth stocks with a longer-term orientation, and continued as the rate-hiking cycle began in early 2022.

Figure 5: Performance of clean energy stocks related mostly to macro developments

We observe a similar trend in ESG leaders’ strategies, where sector exposures typically do not deviate significantly from traditional strategies. As such, performance has been in line with the traditional benchmark under multiple administrations. ESG leaders’ strategies may display a small underweight of the energy sector, which we believe is positioned to benefit from a Trump presidency. This is offset by the small overweight of the financials sector, which also benefits in our “Red sweep” scenario.

US SI strategies have seen outflows since 2022, however, overall net flows are still cumulatively up by USD 105bn since early 2018. Total US sustainable investing fund assets stood at USD 336bn at the end of Q2 this year, meaning cumulative outflows of USD 36bn since 2022 represent an outflow of approximately 10%.

Figure 7: Net  ows in US SI strategies higher in 2024 compared to 2018 baseline

Investments in renewable energy capacity have also been steadily increasing during the Biden administration, as they did when Trump was in office. In 2023, these reached USD 93bn, up from 47bn in 2016 (BNEF, 2024). This has financed a spike in new capacity, with wind generation up 87% in this period, and utility-scale solar up 356% (EIA, 2024). The annual growth rates were similar for both administrations, with a slight uptick during Trump’s four years in office versus Biden’s first three.

In discussing investor and corporate activity on sustainability topics, we would be remiss if we did not mention the adoption of diversity goals among listed US companies over time. US corporate diversity has also improved consistently during both the Trump and Biden administrations. The share of female directors across S&P 500 companies reached 32% in 2023 (up from 23% in 2018, in the middle of Trump’s term), and racial and ethnic makeup reached 25% (versus 20% in 2018), according to a recent report by The Conference Board.

On the development cooperation side, USAID’s budgetary resources (as stated in their annual financial reports) rose from USD 27bn in 2016 to nearly USD 52bn in 2023, reflecting the growth in funding needs and opportunities across emerging and frontier markets.

These examples illustrate a fundamental trend that has an economic and geopolitical foundation and is likely to be independent of election outcomes, as long as investors continue to see the potential for long-term financial returns and opportunities across sustainability and sustainable investments (regardless of whether they are explicitly referred to as “ESG” or not).

In addition to secular trends, it might be worth considering how the more polarized parts of the public respond. Under our “Red wave” scenario, we think it is possible that more private endowment and private foundation assets with a focus on environmental or social issues flow into SI strategies, at least near term, even in the case of reduced activity from state pension funds.

One way to illustrate this is to parallel investors’ potential reaction to some of the evolution in the philanthropy space, where private individuals and families have been largely driving capital flows. According to Giving USA, charitable giving has increased by nearly 30% since 2019, with corporate giving showing the highest growth rates, and individual donors contributing the largest total share. Anecdotally, according to various media reports, donations to Planned Parenthood and similar charitable organizations significantly increased in the early days of the Trump administration, and more recently after the overturn of Roe v. Wade.

Assumptions on both secular and emotional responses carry a degree of risk. Shorter-term market conditions—such as interest rates and inflation—will continue to impact sustainable investments just as they do conventional capital allocations regardless of fundamental trends. In addition, very drastic policy changes—such as complete repeal of IRA or removal of tax benefits for charitable contributions—might pose challenges to continued growth in sustainable investment and philanthropy flows.
