Climate change is one of today’s biggest challenges. To truly build a sustainable future, greater emission reduction efforts by ﬁnancial institutions are a must. At bunq, we care about the planet and we ﬁght for a greener world. We want to set an example in the climate change revolution, for both our users as well as our peers in the ﬁnancial sector.
This document shows how we are committing to the good, green ﬁght. Below you can ﬁnd the risks and opportunities of our current position in regard to the climate, as well as targets and future commitments.
The targets you’ll ﬁnd below are in line with the Paris Agreement to ﬁght climate change and enable the energy transition.
To decarbonize the global economy in alignment with the goals established by the Paris Agreement, everyone must take action. This means ensuring that the global average temperature remains well-below 2°C above pre-industrial levels, and limiting the temperature increase to 1.5 °C. For us, this means “making ﬁnance ﬂows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development”. For banks who invest in residential mortgages, which we do, it requires reducing GHG (greenhouse gas) emissions by half by 2030. This is in line with Paris Agreement’s Article 2.1(c).
To maximize our impact and align our measurable objectives with the maximum global temperature increase of 1.5° C, our commitments are the following:
At the moment, work is needed to estimate the expected future CO₂ reductions for residential mortgages, so that we can commit to a quantitative CO₂ impact per million euro invested target. Because our CO₂ impact per invested million euros is already very low - much lower than most banks - reducing the CO₂ impact per million euro invested by half is much harder for us. Ideally, we would formulate an ambitious absolute CO₂ impact per million euro invested as a target, but it is currently not known what absolute level is consistent with the Paris Agreement goals.
We plan to achieve our commitments above through a combination of actions:
First, we need to minimize the CO₂ impact of our own investments. The impact through investments has three levels:
Second, bunq enables its users to become CO₂-neutral. bunq is offering a variety of products to make carbon offset more accessible on the consumer level, amongst which the planting of trees for every 100 euros spent, empowering users to effortlessly make the world a greener place.
Furthermore, some of the tools in bunq’s app, such as the budgeting tool, may assist users to direct their spending in a climate friendly way.
Third, bunq measures, and will continue to measure, the CO₂ footprint of its activities and investments. By identifying current and future reduction opportunities bunq can remain best in class.
We take pride in offering the best banking experience by building features that our users actually want and need. Many of our users indicated that we should invest responsibly and safely, so Freedom of Choice was introduced in 2019. Freedom of Choice lets them decide where their money is invested. Since then, we have continued to align our investment portfolio with the desires of the bunq community. To help achieve this, all investments are assessed against strict socially responsible investing criteria.
bunq does not ﬁnance, or invest in, companies active in areas that may be deemed not socially responsible. For climate-related risks bunq does not ﬁnance companies active in:
bunq holds several derivative contracts used for hedging interest rate risk. The management of these contracts, including posted collateral, are outsourced to Nationale Nederlanden Investment Partners. The counterparties are typically large banks and the collateral are typically claims on large ﬁnancial institutions and corporations. These parties may be involved in ﬁnancing one or more of the above activities. As bunq is obliged to manage its risks through derivatives, the scope of bunq’s socially responsible investment practices excludes these contracts.
The majority of our users prefer investments to be safe and green. In addition, the Dutch Central Bank has a range of requirements that we must meet.
Per 31 December 2020, our investment portfolio is made up of the following asset classes: cash, Dutch residential mortgages and green bonds. All these investments are safe and the estimated carbon footprint of our investment portfolio is low. Due to changes in the investment portfolio in 2020, the carbon footprint of our investments is estimated to have decreased from 113 tCO₂e2 per invested million, to 193 tCO₂e, making it signiﬁcantly greener! This was an important motivation for selling our old bond portfolio to buy Dutch mortgages.
Currently bunq has no equity investments. However, if this changes in the future, we will engage, propose and support climate-related shareholder resolutions.
Our assets produced 78104 tCO₂e in 2020. How does this compare to other investment portfolios?
Per the end of 2020 our portfolio has a tCO₂e per Invested million value of 9.11. This is very low also due to the still signiﬁcant amounts placed on deposit with the ECB. If we would exclude these deposits then the average tCO₂e per Invested million value is 18.07. To compare, the average ﬁxed income portfolio has a tCO₂e per Invested million value above 100.
Our bond portfolio is outsourced to a.s.r Asset Management. In addition to our own socially responsible investment criteria, this portfolio also has to meet a.s.r ‘s criteria. When investing in corporate and sovereign bonds, we only invest in:
Here’s our current bond portfolio:
PCAF has not yet developed methods for measuring the carbon impact of green bonds, so we currently don't have a reliable, standardised method to quantify the carbon footprint of these investments. However, by deﬁnition, they should have a small or beneﬁcial CO₂ impact. We are committed to measuring the carbon impact of green bonds as soon as a PCAF methodology has been developed.
Dutch mortgages make up just over 50% of our investment portfolio. These mortgages have been sourced from Venn Hypotheken and a.s.r Asset Management. Dutch mortgages are traditionally very safe investments. In recent years, credit losses have been <0.01%5.
To measure and disclose the environmental impact of the mortgage portfolio we use methodologies introduced by PCAF. We use energy labels of homes (if the energy label isn’t available, it’s estimated using national averages) to calculate the average electricity and gas consumption of each property. The graph below shows the energy labels of homes we have funded.
The average electricity and gas consumption per energy label is converted into CO₂e emissions. This conversion is achieved with scope one and two emission factors6. The attribution to bunq is determined by the loan-to-value (LTV) ratio of the mortgage. In other words, if bunq funds half of a house, then we take responsibility for half the emissions of that household.
We use well-to-wheel (WTW) emission factors in our analysis. They account for GHG emitted during the supply chain of the energy. For example, oil needs to be drilled, transported, reﬁned and then transported again. Each of these steps creates GHG’s. WTW emission factors incorporate the GHG from each of these production steps. Other emission factors are less comprehensive, and cover only a part of the supply chain.
Cash makes up slightly less than half of our investment portfolio. The majority of this cash is held with the European Central Bank (ECB), and can be viewed as risk-free.
ECB cash has a small impact on the environment. The PCAF standard does not provide guidance for this asset class, but we have made our calculation by applying PCAF principles. To calculate this impact we use PCAF emission factors to convert the cash into expected GHG emissions.
To calculate our carbon footprint we apply all three scopes recommended by the Global GHG Accounting and Reporting Standards:
Scope 1: the direct use of fuel
Scope 2: the indirect use of fuel due to energy consumption (electricity)
Scope 3: our use of energy through suppliers, inputs, and investments
Being a ﬁnancial institution, most of our carbon footprint is a result of our investments
(which we summarised above). However, we want to improve our direct emissions as well, hence the need to calculate scope one and two emissions.
Scope three emissions also cover carbon emissions from suppliers and outsourcing partners. The breadth of this can be endless. We aim to publish a minimum of 95% of our scope three footprint, focusing on main suppliers like Amazon web services, NNIP and a.s.r.
At bunq we are committed to reducing the direct CO2 impact of our ofﬁces and staff. We reached out to our landlord to request the use of renewable energy sources for both the Amsterdam and Soﬁa ofﬁces, and are working towards a solution. Paper use is minimal at 30pages per FTE per year, but our goal is to become a paperless ofﬁce. Our staff are young and environmentally conscious with 35% commuting to work on bikes and 50% using public transport.
As demonstrated in the table above, ~660k new trees are required to offset bunq’s current annual carbon footprint of 8100 tCO₂e. As shown, the number of trees planted on behalf of our users is three times higher. This more than outweighs the CO₂ impact of activities and investments to service them. Each additional tree planted enables our users to become climate neutral. While the climate is best served if our users reduce the direct CO₂ impact of their activities, the more they use their bunq account, the closer they are to becoming climate neutral.
The direct use of fuel is limited to gas consumption across our ofﬁces (Soﬁa and
Amsterdam), converted to tCO₂e using 1,884 kg CO₂/mვ for natural gas. These emission factors are sourced from CO₂ emissiefactoren.
The indirect use of fuel includes electricity usage in our ofﬁces and employees’ commute to work.
To determine how employees commute to the ofﬁce (train, bike or car), we completed an ofﬁce survey. Kilometers traveled were based on HR data used to calculate commute costs to compensate employees. The number of employees coming into the ofﬁce was based on a normal year. This overestimates bunq’s carbon footprint in 2020 as Covid-19 restricted ofﬁce access.
We use PCAF calculation methodologies when relevant or PCAF principals to calculate all our investment GHG emissions. The most comprehensive calculation was for the mortgage portfolio.
The average gas and electricity consumption per energy label were published in Cijfers over wonen en bouwen 2013. This report by Rijksoverheid summarises the state of housing in the Netherlands. While this is an old report, it is the latest available. Given the average energy output of households have dropped over the last seven years, this leads to an overestimation. The average consumption per energy label can be converted to CO₂ emissions by multiplying with the Dutch energy market WTW emission factors, calculated by CO₂ emissiefactoren. As of January 2020, the factors are 1,884 kg CO₂/mვ for natural gas and 0,475 kg CO₂/kWh for electricity of unknown origin. The results of this calculation are shown in the following graph:
Total portfolio emissions can be calculated by multiplying the number of houses per energy label with the average kg CO₂e output per energy label. For homes with no available energy label data, we apply the market average.
How much of these annual emissions are attributed to us? GHG accounting recommends that attribution is equal to the ratio of the outstanding loan to the initial property value when the loan was originally made. We ﬁx the value of the property so that our carbon footprint does not change with movements in property prices. For the VENN portfolio we can do this calculation on a loan by loan basis. For the a.s.r. portfolio, we were only able to apply the weighted average portfolio LTV due to data limitations.
The mortgage CO₂ calculation for both portfolio’s has a PCAF data quality score of 59. For this to improve we need access to deﬁnite building emissions, instead of using building averages, or base calculations on the property ﬂoor area. We don’t yet have access to this level of data.
As mentioned above, the management of swap collateral is outsourced to Nationale Nederlanden Investment Partners (NNIP). The PCAF Standard does not provide guidance for calculating CO₂ of this asset class, but we have made an approximation by applying PCAF principles. NNIP invests mainly in short-dated ﬁnancial institution notes, which actively change. The most relevant emission factor is the PCAF diversiﬁed ﬁnancials emission factor, therefore, we use this to estimate the CO₂ emissions.
