Unlocking Vietnam’s Net Zero Ambition: Innovative Solutions for a Sustainable Future

Climate Change and the Net Zero Challenge

Climate change is intensifying its impact. In early August 2025, Hanoi recorded a historic high temperature of 40.3°C—the highest ever for the month. Meanwhile, Central Vietnam and the Mekong Delta are repeatedly battered by natural disasters, threatening the lives and livelihoods of tens of millions. Without immediate action, climate change could cost Vietnam 12.5% of its GDP.

According to the United Nations Development Programme (UNDP) in Vietnam, reducing greenhouse gas emissions is the “fundamental key” to tackling climate change. At COP26 (2021), the Prime Minister pledged that Vietnam would achieve Net Zero by 2050. This is a significant challenge, as Vietnam ranks among the top 20 emitting countries, contributing 1% of global emissions. Reports from the UN and the World Economic Forum highlight that buildings and construction account for 38% of global greenhouse gas emissions. In this context, the need to reduce emissions is increasingly urgent.

Guided by the principle of continuous innovation for a brighter future, Mitsubishi Electric is recognized as a “Net Zero Architect.” Beyond providing equipment, Mitsubishi Electric offers comprehensive solutions: from air conditioning systems, elevators, and escalators to intelligent energy management systems, transforming inert buildings into smart, efficient, and sustainable structures.

A prime example is the Net Zero Energy Building (ZEB) SUSTIE in Kamakura, Japan. The building leverages natural light, wind, windows, and awnings to reduce electricity consumption. It also incorporates high-efficiency equipment for comprehensive energy savings. Notably, the rooftop solar panels enable self-sufficiency in energy, making ZEB feasible even in space-constrained urban areas.

With its efficient design and operation, the SUSTIE model has earned prestigious international certifications: the ZEB Certification (BELS, Japan) in 2022 and the S CASBEE Smart Wellness Office Award, recognizing its ability to enhance user comfort and health. In August 2025, SUSTIE received the ASHRAE® Technology Award, cementing its global leadership in green architecture.

As Vietnam strives to achieve Net Zero by 2050, expanding ZEB projects is imperative. At the Net Zero Energy Building event held in Hanoi on September 19, co-hosted by Mitsubishi Electric Vietnam Co., Ltd. and Mitsubishi Elevator Vietnam Co., Ltd., Mr. Takashi Nishikuma, General Director of Mitsubishi Electric Vietnam, stated: “The path to Net Zero is not just a trend but a shared responsibility to secure a better future. Mitsubishi Electric is committed to delivering comprehensive solutions—from air conditioning and energy management systems to safe, durable, and energy-efficient elevators and escalators—helping smart buildings achieve Net Zero emissions.”

The event brought together experts to share insights and solutions, partnering with Mitsubishi Electric to create a green future for Vietnam. As Mr. Nishikuma emphasized, “Technology alone cannot drive significant change without the collaboration of partners, customers, and the community.”

Mitsubishi Electric’s Comprehensive Solutions: A Catalyst for Net Zero Buildings in Vietnam

During the event, Mitsubishi Electric Vietnam Co., Ltd. and Mitsubishi Elevator Vietnam Co., Ltd. introduced an ecosystem of comprehensive solutions to realize the Net Zero Energy Building model in Vietnam, focusing on three core areas:

• The VRF CITY MULTI central air conditioning system and the new-generation Heat Pump optimize energy efficiency, significantly reducing electricity consumption—a critical factor for achieving Net Zero. The CITY MULTI system features inverter compressors, heat recovery technology, precise zone temperature control, modular design, quiet operation, and seamless building management integration. The new-generation Heat Pump uses high-efficiency inverter technology and eco-friendly refrigerants, enabling efficient hot water production even at sub-zero temperatures.

• The building management and monitoring system acts as a “brain,” enabling managers to track, analyze, and coordinate building operations effectively, thereby reducing emissions and operational costs.

• The new NEXIEZ-Fit elevator series, designed for low-rise buildings with up to 10 stops and a capacity of 450–630 kg, embodies sustainability with a sleek design. NEXIEZ-Fit optimizes investment costs while delivering comprehensive value through safety, comfort, and quality. Additionally, Green Technology solutions for elevators and escalators, successfully implemented in key Vietnamese projects, enhance energy efficiency, reduce operational costs, improve safety, and minimize environmental impact.
