Introduction
Transjakarta, Jakarta’s flagship public transportation system, has achieved another milestone by earning the Greenhouse Gas Emission Reduction Certificate (SPEI-GRK). This recognition underscores Transjakarta’s commitment to reducing carbon emissions in the capital city and actively contributing to environmental sustainability. This article will explain what SPEI-GRK is, how Transjakarta earned the certificate and its significant impact on reducing urban carbon footprints.
What is the Greenhouse Gas Emission Reduction Certificate (SPEI-GRK)?
The SPEI-GRK is an official recognition granted to entities or institutions that have taken concrete steps to reduce greenhouse gas (GHG) emissions. GHGs such as carbon dioxide (CO₂), methane (CH₄), and nitrogen oxides (NOₓ) are primary contributors to climate change. The certificate is designed to encourage innovation and initiatives that support environmental sustainability.
SPEI-GRK is issued based on transparent and verified measurement standards, assessing the impact of emission reduction programs on the environment. In urban contexts, implementing environmentally friendly transportation policies is a crucial factor in achieving GHG reduction targets.
How Transjakarta Earned the SPEI-GRK
Transjakarta received the SPEI-GRK through the consistent implementation of environmentally friendly initiatives. The key steps behind this achievement include:
- Introducing Eco-Friendly Fleets: Transjakarta has started integrating electric buses into its transportation services. These buses produce zero exhaust emissions, directly contributing to reducing urban carbon emissions.
- Operational Energy Efficiency: Alongside electric buses, Transjakarta has optimized operational efficiency through well-structured routes. It also utilizes traffic management technology, reducing fuel consumption in non-electric fleets.
- Collaboration with Government and Private Sectors: Transjakarta collaborates with local governments and private entities to support green programs. This includes procuring eco-friendly fleets. It also involves developing electric charging infrastructure.
The certification process involved a thorough audit of emission data. It also included an evaluation of the impact of the implementation emission reduction measures.
Significant Contributions to Reducing Carbon Footprints
Transjakarta’s success in obtaining the SPEI-GRK has had a wide-reaching impact on urban environments. Its notable contributions include:
- Improved Air Quality: The use of electric fleets reduces carbon emissions and other pollutants, such as NOₓ and PM₂.₅, which are major contributors to health issues in big cities.
- Support for the Government’s Green Program: This achievement aligns with Indonesia’s target to reduce carbon emissions by 29% by 2030, in line with the Paris Agreement commitments.
- Raising Public Awareness: This initiative serves as a tangible example for the public and other provinces of the importance of sustainable and eco-friendly transportation.
- Inspiring Other Cities: The Chairperson of the Jakarta Regional People’s Representative Council (DPRD) hopes Transjakarta’s success will inspire other cities in Indonesia to adopt similar policies, accelerating the nationwide transition to low-emission transportation systems.

Conclusion
Transjakarta’s achievement of earning the Greenhouse Gas Emission Reduction Certificate (SPEI-GRK) is not just recognition of its efforts but also solid proof that public transportation can lead the way in reducing carbon emissions. By continuously integrating eco-friendly fleets, Transjakarta supports the government’s green initiatives. This not only improves Jakarta’s air quality but also paves the way for a more sustainable future for transportation.
This step is expected to drive positive change not only in Jakarta but also encourage other cities across Indonesia to contribute more significantly to achieving global emission reduction targets.
