How global cities are promoting sustainability and helping to fight climate change

The commitment by many global cities to sustainable real estate goals is not only the right thing to do from a social perspective, it could make sense for investors too.

The 2016 Paris Agreement gave the world a sense of hope that politicians could work together to limit temperature rises to 2 degrees centigrade. However, much has changed since the milestone agreement. More frequent extreme weather events, increasing political nationalism and growing economic inequality are making the goal of a carbon neutral world by 2050 harder to achieve. Schroders’ Climate Progress Dashboard is currently indicating that global temperatures are likely to rise by 3.8 degrees by 2025

As investors in global cities, we seek to ensure that each holding is analysed on its sustainability credentials during the investment process, including its impact on the environment. On a recent visit to Paris we learnt more about how the publicly listed French commercial and residential landlord Gecina is demonstrating leadership in the transition to a more sustainable city. Paris is ranked 17th in our Global Cities Index and 90% of Gecina’s portfolio is located within the Paris region (as of the end of 2018). Their ambition to own sustainable urban assets is a key reason for our interest in the company.

Global cities lead the charge

With control over local planning, taxes and energy supply, the mayors of leading global cities are setting ambitious climate action plans to meet the targets set by the Paris Agreement. Paris has its own climate agency to deliver theirs and sits on the steering committee of the C40 Cities group that is sharing sustainability best practice globally.


Local real estate owners will play an important role in achieving these plans, as buildings and the construction industry account for around 40% of global carbon emissions.

Eight ways real estate owners can achieve a more sustainable portfolio

  1. Define an ambitious vision

Ambitions are agreed at executive level and structured around the UN Sustainable Development Goals. Getting these targets approved by third parties, such as the Carbon Trust and Science Based Targets initiative, adds validity to this process.

Gecina has committed to becoming carbon neutral by 2050 and has cut its emissions by 32% since 2008, half way to its 2030 target.

  1. Using renewable energy

Energy consumption is a key contributor to overall carbon emissions from buildings, with around 80% still supplied by fossil fuels globally.

Gecina recently developed an office building called “Be Issy”, which produces more energy than it consumes using 960 square metres of photo-voltaic cells and geothermal heat pumps. However, sufficient renewable energy cannot be generated on site in all cases. Much rests on tenants once buildings are occupied, with “green leases” one way to incentivise good practice.

Cities such as Paris are also introducing district urban heat and cooling networks that can improve energy efficiency by 50%. With occupiers seeking to achieve their own sustainability goals, developers hope that such innovations will strengthen tenant demand and landlord pricing power.

  1. Reducing embodied carbon in the development process

The vast majority of emissions come from inefficient older buildings. One of Gecina’s most ambitious projects to date is the redevelopment and consolidation of two former office buildings on Rue De Courcelles, also targeting a carbon neutral design. This includes using wood in the structure to store carbon (and reduce concrete emission intensity), a greenhouse on the roof and renewable energy production.

  1. Reducing waste and recycling old materials

Landlords are seeking to avoid sending waste to landfill by integrating so-called circular economy design principles into their projects. This involves reusing existing property, plant and equipment. For example, two-thirds of the existing marble façade at Gecina’s other major redevelopment – L1ve - is to be reused as flooring in the new building entrance, saving money and cutting waste.

  1. Providing access to low emission transport

Locating new developments near major transport hubs promotes sustainable travel and cuts indirect portfolio carbon emissions. Developers are also increasingly including electric vehicle charging stations in their developments as global cities prepare for a future free of petrol and diesel-powered vehicles.

  1. Reintroducing biodiversity and green spaces

Maintaining existing and integrating new green spaces helps to sustain biodiversity and remove carbon from the atmosphere. Gecina’s L1ve office redevelopment will include 2,800 square metres of gardens and terraces within the building’s footprint.

  1. Accessing sustainable financing 

Green bonds are subject to reporting on environmental and social obligations, with the funds often used to invest in sustainable properties and projects. This new source of capital is growing rapidly. Gecina has structured 20% of its borrowing as “sustainable improvement loans”.

  1. Certifying buildings to “grade A” standards

Financial conditions for Gecina’s sustainable loans are indexed against the group’s corporate social responsibility performance. This includes certifications such as GRESB, which provides ESG benchmarking for real assets. Building certification gives investors, lenders and occupiers confidence that developers’ ambitions around building standards can be achieved. Tracking these standards across a portfolio can demonstrate improvements in energy efficiency, health and well-being, accessibility, connectivity and biodiversity. These attributes are also becoming increasingly important to occupiers seeking happy and productive staff.

Gecina is demonstrating global leadership in its transition to a more sustainable real estate portfolio, seeking to contribute to the ambitious goals of the Paris Climate Agreement. A more environmentally friendly portfolio should benefit from reduced operating costs, better access to capital and stronger tenant demand, thereby also creating an inherently more sustainable business model. We believe this transition is therefore not only the right thing to do from a social perspective, but also makes financial sense for investors.

Gecina is one of the core holdings in the Global Cities Real Estate Fund (as of October 2019) and is used above for illustrative purposes of how a sustainable portfolio can be achieved.

Global Cities Fund - Risk Considerations

Changes in China's political, legal, economic or tax policies could cause losses or higher costs for the fund. The counterparty to a derivative or other contractual agreement or synthetic financial product could become unable to honour its commitments to the fund, potentially creating a partial or total loss for the fund. The fund can be exposed to different currencies. Changes in foreign exchange rates could create losses. A derivative may not perform as expected, and may create losses greater than the cost of the derivative. Emerging markets, and especially frontier markets, generally carry greater political, legal, counterparty and operational risk.

Equity prices fluctuate daily, based on many factors including general, economic, industry or company news. The fund uses derivatives for leverage, which makes it more sensitive to certain market or interest rate movements and may cause above-average volatility and risk of loss.

In difficult market conditions, the fund may not be able to sell a security for full value or at all. This could affect performance and could cause the fund to defer or suspend redemptions of its shares.

Failures at service providers could lead to disruptions of fund operations or losses.
