Could sustainable buildings help us achieve net zero?
Portfolio Manager Tal Lomnitzer highlights the exciting investment opportunities within the resources sector arising from the need for sustainable construction.

- More than 60% of total global emissions stem from the built environment and just over a third of this is attributed to buildings.
- Finding a way to cater to the world’s growing urban population, while ensuring emissions reductions are achieved requires investment in industrial innovation and new practices.
- The momentum behind sustainable construction provides investors in the natural resources sector with opportunities to participate in the long-term global shift to achieve net zero.
Multiple structural shifts are underway across the built environment as it undergoes rapid transformation to reduce its carbon intensity. From planning, construction, usage and decommissioning, there are enormous opportunities when it comes to delivering the next generation of green buildings and infrastructure.
An immense carbon footprint
Urban centres are significant carbon emitters, with more than 60% of total global emissions stemming from the built environment and just over a third of this is attributed to buildings.1
Currently, around half the resources extracted globally are used for housing, construction, and infrastructure and the continuing trend of urbanisation means that 230 billion square metres of new buildings will need to be constructed over the coming 40 years.
With global commitments to achieving a net zero emissions future, finding a way to cater to the world’s growing urban population, while ensuring emissions reductions are achieved, means industrial innovation and new practices will need investment.
Rethinking each stage of the construction cycle
There are opportunities to reduce carbon emissions and intensity at every stage of the building and construction life cycle, and significant investment is already underway.
Lowering the carbon footprint of construction through better building materials processing, optimising design, using recyclable components and improving energy usage are just some pathways to mitigating emissions.
In a return to bygone days, city buildings are once again being constructed from timber, which is both a renewable resource and a store of carbon, replacing materials like concrete and steel, which are far more emissions-intensive, as well as finite resources.
Meanwhile, there is a wave of tech innovation driving efficiencies, shrinking buildings’ carbon footprints. Artificial intelligence-driven controls, Internet of Things (IoT) and sensor technology are helping optimise energy usage – putting a stop to heating, cooling and lighting vacant office spaces, while also making use of on-site renewable energy generation.
In 2021, over US$500 billion was raised for green bond issuances, with 30% of these funds going towards buildings2. Yet this is just a fraction of the investment opportunity, with global investments in green buildings accounting for less than 9% of the US$5 trillion spent on building construction and renovation in 2017.

Research suggests that the green building materials market could achieve a compound annual growth rate of 10.16% in 2030.3 Meanwhile, new sustainable buildings are set to represent a US$24.7 trillion investment opportunity in emerging markets alone.4
The momentum behind sustainable construction, including green buildings and infrastructure, provides investors including those in the natural resources sector with the opportunity to participate in a long-term global shift as an increasingly urbanised world moves to achieve net zero emissions.

Green bonds: a means of raising funds by companies and governments via the debt capital markets for projects that deliver environmental benefits and solutions.
Net zero: refers to the balance between the amount of greenhouse gas produced and the amount removed from the atmosphere. Net zero is reached when the amount of greenhouse gas added is no more than the amount taken away.
Commodities (such as oil, metals and agricultural products) and commodity-linked securities are subject to greater volatility and risk and may not be appropriate for all investors. Commodities are speculative and may be affected by factors including market movements, economic and political developments, supply and demand disruptions, weather, disease and embargoes.
Natural resources industries can be significantly affected by changes in natural resource supply and demand, energy and commodity prices, political and economic developments, environmental incidents, energy conservation and exploration projects.
Sustainable or Environmental, Social and Governance (ESG) investing considers factors beyond traditional financial analysis. This may limit available investments and cause performance and exposures to differ from, and potentially be more concentrated in certain areas than the broader market.

Past performance does not predict future returns. The value of an investment and the income from it can fall as well as rise and you may not get back the amount originally invested.

Please read the following important information regarding funds related to this article.
- Shares/Units can lose value rapidly, and typically involve higher risks than bonds or money market instruments. The value of your investment may fall as a result.
- Shares of small and mid-size companies can be more volatile than shares of larger companies, and at times it may be difficult to value or to sell shares at desired times and prices, increasing the risk of losses.
- The Fund is focused towards particular industries or investment themes and may be heavily impacted by factors such as changes in government regulation, increased price competition, technological advancements and other adverse events.
- The Fund may use derivatives with the aim of reducing risk or managing the portfolio more efficiently. However this introduces other risks, in particular, that a derivative counterparty may not meet its contractual obligations.
- If the Fund holds assets in currencies other than the base currency of the Fund, or you invest in a share/unit class of a different currency to the Fund (unless hedged, i.e. mitigated by taking an offsetting position in a related security), the value of your investment may be impacted by changes in exchange rates.
- Securities within the Fund could become hard to value or to sell at a desired time and price, especially in extreme market conditions when asset prices may be falling, increasing the risk of investment losses.
- The Fund may incur a higher level of transaction costs as a result of investing in less actively traded or less developed markets compared to a fund that invests in more active/developed markets. These transaction costs are in addition to the Fund's Ongoing Charges.
- The Fund could lose money if a counterparty with which the Fund trades becomes unwilling or unable to meet its obligations, or as a result of failure or delay in operational processes or the failure of a third party provider.
