- Cutting-edge environmental technologies are here: Mounting breakthroughs from electric vehicles to carbon capture combined with increasing demand and affordability are helping drive growth for environmental technologies.
- Public and private actions towards carbon reduction: Over $710 billion in global environmental spending earmarked towards environmental technologies and over 8,000 corporations signed up for the race to zero campaign, which prioritizes cutting global emissions in half by 2030.1,2,3
- Early-stage technologies are driving innovation: We believe investors may benefit from exposure to ETFs designed to invest in a broad basket of nascent environmental technologies such as pollution reduction, energy efficiency, and breakthroughs in transportation and power.
THE KEY DRIVERS OF NEXT GENERATION ENVIRONMENTAL SOLUTIONS
We see three key reasons why next-generation environmental technologies will be increasingly important in our economy:
First, governments and companies around the globe have made ambitious climate commitments to reduce emissions, and have passed legislation such as the Inflation Reduction Act which designated nearly $400B towards clean energy technologies and electric vehicles.4 Countries representing nearly 90% of the world economy now have net-zero commitments.5 The private sector has also made commitments, with more than one-third of the world’s largest publicly traded companies announcing carbon reduction targets.6 However, the private sector is not just making commitments, they are also following through with their wallet. For example, in 2021 corporate venture capital arms invested $23.2B in businesses in the climate tech sector, more than double the 2020 investment.7 Companies know that meeting these commitments requires leveraging environmental technology breakthroughs across areas such as green transportation, renewable energy and energy efficiency, which have the potential to significantly offset the growth of greenhouse gas emissions.
Second, the shift toward renewable energy has accelerated in some markets amidst a global focus on energy security. For example, Germany announced plans to accelerate their transition to renewables, bringing forward their target for 100% renewable power by 15 years, to 2035.8 New government policies around the globe will lead to annual clean energy investments of more than $2 trillion by 2030, a 50% increase from today’s levels.9
Finally, consumers are reporting increased interest in sustainable products. Whether its buying electric vehicles, installing cutting-edge solar panels on their roof or installing smart meter technologies in their home to reduce energy usage, consumers may continue to turn towards environmentally friendly technologies and products.

THE POTENTIAL BENEFITS OF GETTING THERE EARLY
If investors are looking to gain access to environmental technologies, they may want to consider focusing on companies whose products and services are in the early stages of adoption. Later-stage companies are typically larger and more mature, and already found in broad equity benchmarks such as the S&P 500.
For example, rewind the clock to 2010, when renewable energy’s share of US electricity generation was 10%. Fast forward 10 years and renewable’s share doubled to 20%.10 During this timeframe the S&P Global Clean Energy Index outperformed the S&P 500 energy index by 74%.11 We believe accessing environmental technology companies ahead of their acceleration in adoption could benefit investors, as the transition becomes more fully priced.

KEY BREAKTHROUGHS IN ENVIRONMENTAL SOLUTIONS
Below we highlight eight themes that could shape the future of environmental technologies,12 whose potential opportunity may be significant. Click into each of these themes to learn more.
1. GREEN TRANSPORTATION
Did you know? Electric trains emit 20% to 35% less carbon per passenger mile than a diesel train.13
The green transportation theme refers to companies involved in the provision of sustainable transportation products and services such as electric vehicles (EVs) or charging stations. Solid-state batteries are demonstrating key advantages over the more commonly used lithium-ion batters, including higher energy storage density, longer life, and faster charging. Lithium-ion batteries tend to start degrading after 2,000-3,000 charges, whereas solid-state batteries can be charged up to 10,000 times before noticeable degradation.14
The big picture: EVs could represent 60% of new car sales by 2030,15 up from 10% in 2022.16 (Read more about how tax credits, government EV purchases, loans and grants could boost the entire EV value chain.)
2. RENEWABLE ENERGY
Did you know? 2/3 of renewable power added in 2021 had lower costs than the cheapest coal-fired options in G20 countries, and renewables saved the US $55 billion in energy generation costs in 2022.17
One of the criticisms of solar energy is its reliance on the whims of the sun. This becomes an issue for power grids reliant on solar as the most efficient energy storage systems can only store a charge for one to five days. However, recent breakthroughs in a technology called “molecular solar thermal energy storage” (MOST), relies on a very thin chip that can store solar energy in liquid form, for up to 18 years, significantly improving the reliability of solar powered energy sources.18
The big picture: As the transition unfolds, there may still be a large runway for renewables given fossil fuels still supply 82% of the world’s energy.19
3. ENERGY EFFICIENCY
Did you know? Energy efficient appliances could save U.S. households up to 25% on their utility bills, amounting to over $2,200 annually.20
The energy efficiency theme seeks to reduce waste or usage, and traditional heat pumps have plenty of room for improvement. Traditional heat pumps move energy from the outside to heat or cool a home, which is 2-to-3 times more energy efficient than burning fossil fuels to warm the same space. New, innovative heat pumps leverage renewable energy sources to power the heat transfer, reducing emissions by 50% or more.21
The big picture: Global investment in energy efficiency reached $560 billion in 2022 and is projected to increase nearly 50% by 2030.22
Did you know? Over 700 million people live in countries with significant water stress.23
The water theme is focused on areas such as water efficiency technology or water treatment services. For decades, traditional water meters measured the flow of water for businesses and residential homes, to track usage and properly bill customers. Smart water meters leverage technology to track usage in real-time, enabling early detection of irregularities in usage, alerting clients to any issues before they become widespread.
The big picture: The Drinking Water and Wastewater Infrastructure Act of 2021 included $55 billion in spending for restoration and improvement of water and wastewater systems in the United States.24
5. GREEN BUILDINGS
Did you know? Residential and commercial buildings represent nearly 40% of CO2 emissions in the U.S. and 80% of U.S. buildings that will be in use in 2050 are already built.25 Retrofitting existing infrastructure with new technologies will be key to reducing emissions.
The green building theme refers to the design, building and retrofitting of existing physical infrastructure to produce lower emissions. Solar panels have been placed on rooftops for a long time; solar inverters are the latest breakthrough in solar technology. Solar inverters convert electricity from a solar panel into the same current as what a grid requires,26 and are now being leveraged inside glass windows and walls for modern green building construction.
The big picture: According to a recent McKinsey report, decarbonizing existing buildings could be a $1.9 trillion market.27
6. POLLUTION, PREVENTION, AND REDUCTION
Did you know? Air pollution was a contributing factor to nearly 12% of global deaths in 2021.28
This theme targets companies whose products and services are involved with reducing pollutants emitted or capturing previously emitted pollution. For example, traditional carbon capture technology retrofits existing industrial plants so that chemicals can prevent CO2 from being emitted at the source.29 The next innovation is direct carbon capture, which relies on chemical reactions “to pull carbon dioxide out of the air”, including carbon which was released years ago.30
The big picture: According to the International Energy Agency, carbon capture and storage technology could contribute more than 20% of emissions reduction required from the industrials sector.31
7. RESOURCE EFFICIENCY
Did you know? Our economy consumes 100 billion tons of material each year and wastes over 90% of that material.32
Resource efficiency companies support a circular economy, and their products and services enable activities such as recycling or resource recovery. As the electrification of transportation continues, recycling precious metals from batteries has become increasingly important. Traditional recycling methods, called pyrometallurgy, required melting down the batteries and burning off the plastic to extract the precious metals, emitting toxic gases.33 New recycling technologies involve a chemical process which allows fresh lithium to be added to the battery, to return it to full charging capacity.34
The big picture: The circular economy, an economy that give incentives to reusing products rather than extracting new resources,35 is expected to grow from $1 trillion in 2025 to $4.5 trillion in 2030.36
8. SUSTAINALE AGRICULTURE, FOOD & FORESTRY
Did you know? Agriculture accounts for over 11% of U.S. GHG emissions.37
Plant-based meat was first introduced into our lexicon in the 1970s, but lab-grown meat is earlier in its adoption. Lab-grown meat is grown from cells harvested from an animal. One tissue sample taken from a cow can create up to 10,000 kg of meat, meaning 150 cows could feed the entire global population without slaughtering a single animal!38
The big picture: By 2050, there will be over 9 billion people on the planet, and food production will need to increase by 70% to meet growing demand.39 (Learn more about investing in food innovation and ag tech.)
A DIFFERENT WAY TO INVEST IN ENVIRONMENTAL TECH
With popular equity benchmarks such as the S&P 500 index lacking material exposure to environmental tech themes such as renewable energy, green transportation, and energy efficiency,41 a thematic investing strategy that delivers exposure to multiple environmental tech themes could make sense. For example, the Morningstar Global Emerging Green Technologies Select Index targets innovative companies with >25% revenue exposure to the eight themes listed below.
|Emerging Green Technology Category||Weight in Morningstar Global Emerging Green Technologies Select Index|
|Pollution prevention and reduction||5%|
|Resource efficiency, technologies, and services||4%|
|Sustainable agriculture, food, and forestry||0%|
Source: Morningstar, Holdings as of 02/20/23. Weights reflect holdings in Morningstar Global Emerging Green Technologies Select Index.
The index is specifically focused on capturing companies whose products/services are “emerging green technologies”, defined as being in the innovators through early majority stage of the Rogers adoption curve,42 which means at least 50% of the product’s adoption has yet to occur.
Roger’s Innovation Adoption Curve
The %’s reflect the % of consumers which have adopted a product.
Source: Morningstar Global Emerging Green Technologies Select Index.
Chart description: The above chart is an illustration of the Roger’s innovation adoption curve, which measures the cumulative rate at which a population adopts a product or service over time. The adoption stage is determined by assessing the total addressable market and market share (e.g., EVs represented <9% of total car sales in 2021, therefore EVs would fall into the Early Adopters section of the adoption curve).
Sixty-eight years after the first ever piece of federal air pollution legislation,43 the world has transitioned to an era of increased focus on the environment, impacting all areas of the economy. A wide swath of environmental technologies could be positioned to benefit, and investors may want to consider ETFs that hold pure-play firms across the full value chain of environmental technologies, targeting themes such as green transportation or clean energy.
