Jakarta integrates climate resilience into its infrastructure

The centrepiece of the event was the official unveiling of the Governor’s Regulation Number 5 (Pergub) on Energy and Water Efficiency in Buildings. With the building sector accounting for nearly 60 per cent of Jakarta’s total GHG emissions, this regulation provides the critical legal framework to enforce sustainability standards across the city’s built environment.

Some of the expected outcomes include:

• Strengthened policy framework: alignment of green building policies with national goals and Jakarta’s 2030-2050 climate targets
• Institutional capacity: training for more than 700 stakeholders and hundreds of city officials through initiatives like the Jakarta energy management programme on operators’ learning (Jempol) Energy Management Programme
• Data-driven governance: development of an Energy Data Management System (DMS) and a redesigned Regional GHG Inventory System (SIGD) for real-time emissions tracking.

As part of the event, an exhibition shared best practices for green building implementation in both private and Jakarta-owned (BUMD) buildings. Featured case studies and tools included:

• Implementation guidance for building efficiency: a guide designed to help the public and building owners navigate and comply with the Jakarta Governor Regulation on Energy and Water Efficiency in Buildings
• Specialised standard operating procedures (SOPs): technical modules tailored for five distinct building typologies in Jakarta, providing operators with clear instructions for maximising energy and water efficiency
• Jakarta energy management programme on operators’ learning (Jempol) mascot & video campaign: a creative public engagement initiative featuring the Jempol mascot to inspire sustainable energy consumption habits and lifestyle changes
• Jakarta Net Zero Carbon (NZC) building roadmap: a strategic framework outlining the pathway for Jakarta’s building and energy sectors to achieve Net Zero emissions by 2050
• Inclusive climate action guidelines: a diagnostic guidebook developed to ensure that urban climate policies are equitable and inclusive for all citizens
• Green building showcase: featured case studies of successful sustainable architecture and operations in Jakarta, including Menara Astra, SDN Ragunan 08, and Graha Niaga.

“This programme is the UK-Indonesia Strategic Partnership in action,” said Dominic Jermey, British Ambassador to Indonesia. “Launched last month by Prime Minister Keir Starmer and President Prabowo Subianto in London, the Strategic Partnership places climate action at its core and today shows how that shared commitment is being translated into real tools and lasting capacity for Jakarta.

“Today’s launch of the Governor Regulation on Energy and Water Efficiency in Buildings underscores Jakarta’s climate leadership and provides a clear roadmap for a more sustainable urban future. We are proud of what we have achieved together and look forward to deepening our collaboration with Jakarta in the years ahead.”

Murali Ram, C40 Regional Director for East, Southeast Asia and Oceania, added: “The launch of Jakarta’s new green building regulations is a turning point in the city’s climate journey. By addressing the building sector – the source of nearly 60 per cent of the city’s emissions – Jakarta is moving beyond planning and into high-impact implementation.

“Through the UCAP CAI programme, we have seen first-hand how technical rigour, data-driven governance, and inclusive policymaking can transform urban landscapes. Jakarta is not only securing its own climate future but is setting a powerful example for cities across Southeast Asia and the world on how to scale sustainable innovation equitably.”
