News Release UOB and SP Group partner to offset 100% or more of household electricity carbon emissions for UOB EVOL cardholders Cardholders can now achieve their sustainability goals seamlessly and conveniently when they charge their utilities bills to their card Singapore, 23 November 2022 – UOB EVOL cardholders will now be able to offset 100 per cent or more of their household electricity carbon footprint for free when they charge SP Group’s (SP) utilities bills to their credit card, via a new exclusive feature jointly launched by UOB and SP this month. With this new feature, when customers charge SP utilities bills to their UOB EVOL card, UOB will fund and contribute 2 per cent of the billed amount to purchase My Green Credits on the SP app on behalf of the customer. My Green Credits is an affordable and convenient way for customers to get on the sustainability movement by greening their energy consumption through the purchase the amount of “green credits” in the form of Renewable Energy Certificates (RECs)1. For example, when customers charge a $90 utilities bill to their UOB EVOL card, they will receive $1.80 worth of complimentary My Green Credits from UOB, equivalent to 2% of the billed amount. My Green Credits is purchased at a cost of S$0.12 per 25 kWh, which will translate to offsetting 375 kWh (kilowatt hour) or equivalent to an average national 4-room HDB flat’s electricity usage. This is equivalent to offsetting 100 per cent of the home’s electricity carbon footprint (see Annex for illustration). New UOB EVOL cardmembers paying their SP bills via the SP app will automatically enjoy the complimentary My Green Credits, while existing cardholders who are using the SP app to pay their bills before 10 November 2022 will simply need to do a one-time re-add of their EVOL card as a payment method to be eligible. My Green Credits will be automatically reflected within the customer’s SP app, with no additional effort required from them when bill payments are made. This benefit is available for both one-time and recurring SP bills payments. UOB EVOL card is the first in the market to partner with SP Group, Singapore’s national grid operator and leading sustainable energy solutions provider in the region, to offer customers complimentary My Green Credits when they use their EVOL Card to make utilities payment. This feature is applicable to all existing and new EVOL cardholders. The My Green Credits purchased will go towards supporting sustainable energy project developments in the region for the generation of green energy. 1Renewable Energy Certificates (RECs) are tradable green energy attributes that represent units of electricity generated from renewable energy generation facilities. These facilities comply with and are registered under internationally recognised standards, such as the I-REC standard, and are eligible to be issued RECs for every unit of electricity generated. A credit card that supports the green initiative UOB EVOL card is designed to appeal and serve the needs of younger customers, particularly their increasing focus on sustainability. The UOB EVOL Card is Southeast Asia’s first credit card to use bio-sourced materials to minimise ecological footprint. The EVOL Card is made of 84 percent polylactic acid (PLA) and created from renewable sources which are safe for incineration process. An EVOL Card that has expired and discarded is biodegradable in an industrial facility. Each EVOL card cuts down the use of plastic by 84 per cent and reduces carbon footprint by 10 grams per card. EVOL card also has a strong partnership with over 30 green partners to increase customers’ awareness of sustainability in their daily spending. This new card feature is another innovative initiative to further help them contribute to sustainable efforts seamlessly and conveniently. Ms Jacquelyn Tan, Head of Group Personal Financial Services, UOB, said “We understand that every customer has unique needs, preferences and goals, and this drives us to do right by them, to serve them in a way that meets their needs. Our wide suite of credit cards provides a comprehensive range of benefits and rewards to cater to different groups of customers on their differing needs. Through our partnership with SP, we are happy to further support the younger generation’s sustainability goals with our UOB EVOL card. This also shows UOB’s commitment towards sustainability, as we empower customers to work with us to tackle climate change and to forge a more sustainable future together.” Mr Luke Tang, Head of Strategy and Sustainability, SP Group, said “We are pleased to partner UOB to catalyse behaviour that promotes sustainability and the use of renewable energy certificates on the SP App to green household electricity consumption. As younger customers chart their sustainability journeys, we look forward to empowering them with green platforms and resources and collectively accelerate Singapore’s progress towards net zero.” The SP app was launched by SP as the first sustainability lifestyle app in Singapore. It aims to incorporate green solutions and initiatives to provide users with insights and solutions to manage their utilities and to reduce their carbon footprint. In addition to My Green Credits, users can also use the app to manage their utilities, reduce electricity consumption and contribute to Singapore’s sustainability targets to achieve a low-carbon future. On another sustainable front, as part of the UOB EVOL Card My Green Credits launch, SP supported National Parks Board’s (NParks) OneMillionTrees movement to plant a million more trees across Singapore by 2030 through NParks’ registered charity and IPC, Garden City Fund’s Plant-A-Tree programme. UOB and SP will plant 50 trees in April 2023, bringing us closer to realising our vision of becoming a City in Nature, a key pillar of the Singapore Green Plan 2030. Strategic partnership to create better solutions for customers This year marks the fourth year of partnership between UOB and SP, with joint efforts to empower customers on their green goals. Previous collaborations include the purchase of RECs through SP as part of a National Day promotion in 2021 for the EVOL card. UOB has also launched an API with SP in 2020, to allow UOB customers to instantly use their UNI$ to off-set their utility bills. Moving forward, UOB will work with SP to launch another new feature in the first quarter of 2023 that allows UOB cardholders to use their UNI$ to redeem for My Green Credits via the SP mobile app. They can choose which local or international renewable energy projects that they would like to support with the My Green Credits redeemed. Under the My Green Credits initiative, SP is supporting various green projects ranging from a solar farm in Vietnam, to a wind farm in Thailand, to a solar rooftop system in Singapore, to help reduce emissions and impact on the environment. In line with Singapore’s strong push to electrify its vehicle population, ecosystem, UOB and SP also have plans to provide promotional offers to customers who use their UOB cards to pay for electric vehicles (EV) charging at SP EV charging points. Over the past 2 years, UOB has been building up a suite of sustainable future solutions to make it simpler for customers to create impact with their everyday choices. The Bank has an established sustainable investing approach which set standards for its Singapore and regional footprint by curating a suite of sustainable investments across funds, bonds and structured products. This includes its first UOB Personal Financial Services (PFS) secured loans green product framework, serving as the foundation of its Go Green home and car loans. The framework leverages insight from Morningstar Sustainalytics, a leading global provider of ESG research, ratings, and data. In November 2022, UOB also will be availing a digital doorway to sustainable banking on the UOB TMRW app, allowing customers to easily access green deals, investments and banking products on mobile.

Media Release SP GROUP SETS UP FIRST ZERO-EMISSION BUILDING POWERED BY GREEN HYDROGEN IN SOUTHEAST ASIA Singapore, 30 October 2019 – SP Group (SP) has established the first zero-emission building in Southeast Asia that is powered by green hydrogen. Located at SP’s training centre at Woodleigh Park, the self-sustaining building is 100% powered with renewable energy via an innovative Hydrogen Energy System and is disconnected from the national electricity grid. Mr Brandon Chia, Head, Centre of Excellence, SP Group said: “Buildings contribute 40 per cent of energy related carbon emissions worldwide 1 . The Hydrogen Energy System provides a safe and compact way of storing green hydrogen which powers the region’s first zero-emission building. We believe this can be a significant contributor toward Singapore’s climate change pledge to cut national emissions intensity by 36 per cent below 2005 levels by 2030.” The challenge to achieving zero emission The world in its fight against climate change is using various means to lower carbon emissions. One way is to use renewable energy sources. However, in urban places such as Singapore, due to limited land and inconsistent solar energy, achieving zero emission with 100% renewable energy is extremely challenging. Zero-emission solution An alternative is hydrogen as a green energy source. In the Hydrogen Energy System used by SP, electricity from green sources, such as solar, is used to conduct electrolysis. The hydrogen generated from this process is bonded with special metal alloy powders to form metal hydride, compacted and stored in tanks. When electricity supply is required, the stored hydrogen from the metal hydride tanks is slowly released and converted to electricity via fuel cells. As green energy sources are used for electrolysis, this entire process of converting hydrogen to electricity is 100 per cent green, with zero carbon emission. 1 The buildings and building construction sectors combined are responsible for nearly 40% of total direct and indirect CO2 emissions (International Energy Agency). 1 Safe hydrogen storage While there have been other energy systems using hydrogen as a fuel, the key challenge of hydrogen lies in having a storage solution that is safe for deployment in highly-urbanised areas such as Singapore. The system uses special metal alloy as a storage medium to bond with hydrogen. This allows for the storage of a large volume of hydrogen at a much lower pressure over a long period of time without any deterioration. When electricity is needed, the stored hydrogen is released in a slow and regulated manner, making it safer and more compact to be stored in an urban setting. Encourages greater mix of renewable energy The Hydrogen Energy System can mitigate electricity supply fluctuations and intermittency issues – common shortcomings of renewable energy. When there is surplus renewable energy, it can be stored in the form of hydrogen and converted back to electricity when there is a deficit of renewable energy. This ensures that the grid remains stable even with a greater mix of renewable energy introduced, hence encouraging the use of green energy. SP is working with Marubeni Corporation and Tohoku University on the Hydrogen Energy System with special metal alloy storage tanks from Japan, and to customise and integrate it for use in Singapore. -Ends- 2 About SP Group SP Group is a leading energy utilities group in the Asia Pacific.

These Caltex service stations will be equipped with 50kW direct current (DC) fast chargers that can charge up an EV in 30 minutes, versus a few hours required by the more commonly available alternating current (AC) chargers. Three service stations will each be equipped with one 50kW direct current (DC) fast charger. The fourth, at Changi, will have two 50kW DC charging points that are designed to allow a compatible car to charge up to a speed of 100kW, provided only one car is utilising the charging points. (Refer to the annex for the addresses of this first batch of service stations.) SP and Caltex will study EV charging usage patterns and behaviour at the stations to refine and enhance accessibility and utilisation, and plan for more charging points and locations. Group Chief Executive Officer of SP, Mr. Stanley Huang, said, “We are pleased to partner Caltex in our first collaboration with a fuels and lubricants retailer. This gives EV drivers greater convenience as it accelerates the accessibility of charging locations that are incorporated in our daily activities. Our aim is to build Singapore’s largest public EV charging network and expand our integrated green mobility solutions to meet the evolving needs and sustainability goals of businesses and individuals.” "Chevron is excited to partner with SP Group to provide EV chargers at selected Caltex stations in Singapore. It is Chevron’s goal to deliver affordable, reliable, and ever-cleaner energy that enables human progress," said Mr. Law Tat Win, Chevron Singapore Country Chairman. "We 1 endeavour to continually test, learn and explore how to enhance our product and service offerings for our Singapore customers at our Caltex stations.” This SP and Caltex partnership will better serve drivers choosing electric vehicles and help achieve a lower-carbon future for Singapore. This includes Caltex’s existing commercial customers who plan to electrify their fleets. Both companies will continue to explore initiatives to meet the EV needs for private ownership and commercial use. The chargers will be installed by the second quarter of 2021 and will be incorporated on the SP Utilities mobile app for ease of use. The SP Utilities mobile app allows EV drivers to search for the availability of the nearest charging points, receive real-time updates on their charging sessions and make direct, cashless payment. -Ends- 2 About SP Group SP Group is a leading utilities group in the Asia Pacific, enabling a low-carbon, smart energy future for its customers.
