Low carbon lifestyle programs have been introduced in the Kuala Lumpur Low Carbon Society Blueprint 2030 (KL LCSBP 2030) with the slogan “70 By 30: A Greener, Better Kuala Lumpur” as a city with lower carbon emissions in every aspect of life. The community plays an essential role in achieving a low carbon lifestyle by exploring their daily routines in adapting and applying green practices. The phenomenological research methodology will capture participants’ lifestyles and the phenomenon’s essence. This study investigates low carbon lifestyle practices among communities and stakeholders to reduce carbon dioxide (CO2) emissions. It is also related to Sustainable Development Goals (SDGs) such as SDG 2, SDG 11, SDG 13, and SDG 17. Data analysis was done using the purposive sampling method from April to October 2021. Semi-structured interviews were conducted with three informants who are actively involved in Local Agenda 21 Kuala Lumpur (LA21KL) and two stakeholders. The NVivo 12 software was used to compile and analyse the initial code data, develop provisional categories, and incorporate them into themes. Three themes have been determined: Community Engagement and Empowerment, Sustainable Leadership, and Communication Strategies. Lifestyle practices have become part of community life, creating environmental awareness and contributing to Kuala Lumpur's carbon-neutral target of being a low carbon city by 2030.
