Carbon Neutral Real Estate Fund

Carbon reduction through commercial real estate investment

Climate change is firmly back on the agenda. As large asset owners, institutional investors have an important role to play in helping to reduce carbon emissions.

UK office buildings are bad offenders, contributing around a fifth of total carbon emissions in the UK. New build, carbon-compliant real estate only accounts for 1-2% of total supply. To meet the Government’s 2050 carbon reduction targets, emissions from existing buildings will need to be reduced by 80%. Realistically, this can only be achieved via refurbishment.

As large investors and investment managers we have the ability – and the responsibility – to help drive positive outcomes for society. We have one of the largest and most experienced UK property teams and in 2010 took a pioneering step towards carbon reduction by teaming up with Stanhope, one of the leading commercial developers and the Carbon Trust, a world-leading adviser to businesses, governments and the public sector on carbon reduction.
In March 2010 we launched the Low Carbon Workplace Trust and assembled a team of industry leaders in property investment management, design, carbon engineering/refurbishment and carbon compliance. Together with our partners we identify suitable office buildings and turn them into modern, energy-efficient workplaces, while at the same time generating returns for investors. We then let and manage the buildings to ensure ongoing management and reduction of energy wastage.
Reflecting the certification of its office investment portfolio to operational carbon neutrality in 2019, the fund changed its name to the Threadneedle Carbon Neutral Real Estate Fund (‘the Fund’) in May 2020. The name change reflected the status of the Fund as a pioneer of carbon reduction in commercial real estate assets through value-add refurbishment and continued operational carbon neutral management.
As large asset owners with stewardship responsibilities, institutional investors are increasingly looking for a responsible, tangible aspect to their investments, whether social or environmental. This is increasingly mirrored by the demands in the occupational market and we are seeing sustainability and carbon neutrality credentials being high on tenant’s agenda when considering stock selection.
The Carbon Neutral Real Estate Fund concept is economically viable, socially responsible, repeatable, scalable and profitable. It is a great example of the private sector taking the initiative and developing new commercial models that unlock the value in low carbon refurbishment.

Investment Process

Step 1: Identification

Columbia Threadneedle Investments leads in the identification of suitable redundant/obsolete/vacant/short-term let office property showing the optimal combination of location, building fabric, original construction, configuration and local market conditions, offering the potential for a desirable occupational solution that will benefit from a Low Carbon Workplace refurbishment.

Step 2: Economic assessment

The rigorous economic assessment by all three Partners to confirm the achievability of an economic, risk adjusted, profitable and low emission end product, which meets the needs of both occupiers and investors. The entry price, carbon engineering/ refurbishment budget and rental value equation will be computed under a number of potential scenarios.

Step 3: Carbon engineering/refurbishment

The ‘on site’ phase, where Stanhope and the Carbon Trust work in tandem to deliver the agreed physical and carbon specification, within the agreed budget and time scales. Concurrently, Columbia Threadneedle Investments leads early engagement with the potential occupiers, supported by the Carbon Trust.

Step 4: Completed projects and continuing carbon appraisal

Following and during the completion of projects the Carbon Trust applies rigorous carbon oversight of the strategy’s development and investment portfolios. Such oversight includes maintaining ongoing occupier engagement under the Low Carbon Charter, in order to provide training, support and assistance to occupiers with the target of ensuring annual certification under the Charter. This level of continuous occupier engagement provides the strategy with a clear competitive edge over its peers and increases the likelihood of occupier retention.

Step 5: Portfolio management

The strategic asset allocation of the portfolio is reviewed by reference to Columbia Threadneedle Investments assessment of the UK Investment Market and the relative prospects for the underlying geographical areas. Columbia Threadneedle Investments utilises the capabilities of its large and long-established investment team and seeks to generate outperformance in line with similar track records of Columbia Threadneedle Investments-managed property funds.

Low Carbon Workplace Standard

Carbon Neutral Real Estate Fund building occupiers’ energy and carbon performance is monitored and assessed against the Carbon Trust’s Low Carbon Workplace Standard. Occupiers that successfully meet the criteria are awarded with certification to the Standard.

The Carbon Neutral Real Estate Standard assesses three things:

  • Quantitative performance: Workplace carbon emissions are quantified per unit of floor area and per person. Occupiers must either meet best practice emissions benchmarks or demonstrate year-on-year improvements.
  • Qualitative criteria: Occupiers are assessed against a set of broad sustainability performance indicators, together with occupant satisfaction. This assessment provides a holistic picture of the workplace’s overall environmental performance.
  • Carbon management: Occupiers are required to have implemented a carbon management system that embeds energy efficiency and carbon management in the day-to-day activities of the workplace.


In 2015, the Low Carbon Workplace Partnership won three industry awards.

Guardian Sustainable Business Award

In May, The Carbon Trust has been presented with a Guardian Sustainable Business Award in recognition of its innovative and unique approach to reducing the carbon footprint of non-domestic buildings.

The Carbon Trust’s Low Carbon Workplace partnership took home the innovation award in the Built Environment category for the retrofit of Mansel Court, a 1960s office block in South West London. Judges praised the Carbon Trust’s pioneering approach to building refurbishment, overcoming many of the barriers to realising the value in sustainability due to split incentives between property funds, landlords, and tenants.

"The redevelopment of old buildings, while not a sexy task, is exactly where more works needs to be done. Old buildings have a big negative impact and the redevelopment of Wimbledon’s Mansel Court, into a low carbon workplace, was considered a project others could learn from and replicate."

Real Estate Manager of the Year

In July, Columbia Threadneedle Investments won the Real Estate Manager of the Year Award at the Investment Excellence Awards 2015. Now in their 15th year, the Investment Excellence Awards by Global Investor recognise outstanding achievements by asset managers, investment consultants and fund administrators.

With climate change firmly on the agenda, the partnership and its refurbishment of outdated UK commercial properties to a low carbon standard strongly impressed the independent judging panel, which included representatives from the BOC Pension Scheme, the Pensions Protection Fund, Aon Hewitt and others.

Investment Excellence Awards 2015
CIBSE Refurbishment Project of the Year 2015

The refurbishment of Premier House, a 1970s concrete/brick-skinned office building, was one of the first projects to be undertaken by Low Carbon Workplace, a collaboration between The Carbon Trust, Columbia Threadneedle Investments, and Stanhope. The building was typical of its age and type: existing services included an inefficient, high-energy-usage, high-carbon-emitting, VAV air conditioning system with split system DX cooling units.

Using existing mainstream technologies, the refurbishment set out to introduce low-carbon design techniques and technologies for internal climate environmental control and ‘sustainable’ solutions, to achieve a building with low emissions and low water use. The building fabric and structure were generally retained, with principal improvements consisting of replacement windows, upgraded insulation, provision of external solar shading, exposing the building thermal mass, provision of an active, ventilated chilled-beam comfort cooling and heating system, new energy-efficient central plant and a low-carbon lighting system.

A key aspect of the refurbishment was the provision of facilities and systems that allowed occupants to take responsibility for and control of their energy usage and emissions. Extensive individual energy metering was therefore provided to each tenant for the various systems and sub-systems. Tenants were also required to sign the Low Carbon Charter, indicating their firm intention to minimise the building’s energy consumption and emissions. The Carbon Trust then worked with them to develop their Cat B fit-out plans and continues to provide ongoing support to tenants, including monthly reporting on carbon emissions.

This has enabled the identification and realisation of opportunities to improve performance. At the end of the first full year of occupation, energy consumption had been reduced by 64%. This equated to a reduction of 370.9 tonnes of CO2 per year.
