Our History

CSTEP marks 20 years of policy impact, innovation, and scientific research in service of a cleaner, more sustainable India. The number of employees continues to grow as CSTEP expands its efforts in clean energy, air quality, climate resilience, and inclusive development.

CSTEP expanded its Rooftop Solar Explorer (RTSE) platform to the state of Chhattisgarh, accelerating rooftop solar adoption.

CSTEP established an air pollution lab at its Bengaluru office to test and calibrate low-cost air quality sensors, advancing in-house air quality monitoring capacity. Its certification as a Scientific and Industrial Research Organisation (SiRO) was renewed. CSTEP developed an energy transition roadmap for the state of Kerala to achieve net-zero emissions by 2050. It launched the Rooftop Solar Explorer (RTSE) tool in multiple cities across Madhya Pradesh. The Earth Initiative was launched to integrate art into climate communication, making climate messages more accessible to the public.

CSTEP was recognised as one of the Top 20 Best Public Policy Companies in India by Inventiva, a leading business magazine. It was appointed to the Technical Advisory Committee of Experts under the MoEFCC. CSTEP joined the core working group for drafting the Karnataka State Action Plan on Climate Change. It also became a member of the BESCOM Rooftop Solar Committee, furthering its work in solar energy deployment. CSTEP submitted the Karnataka Power Sector Roadmap 2032 to the Power Company of Karnataka Limited (PCKL).

CSTEP was invited by NITI Aayog to contribute to discussions on reviving India’s economy following the COVID-19 pandemic. It became a member of the India Climate and Energy Modelling Forum, constituted by NITI Aayog to strengthen evidence-based climate and energy planning. CSTEP was appointed to the task force created by the Chief Minister of Karnataka for drafting the Research, Development, and Innovation Policy for the state. Its SAFARI model was used by NITI Aayog to project ethanol demand scenarios for the ‘Roadmap for Ethanol Blending in India (2020–2025)’ and the ‘Vision 2035’ document. It also signed an MoU with Karnataka State Pollution Control Board (KSPCB) and BBMP to implement the National Clean Air Programme (NCAP) in Bengaluru. CSTEP’s pilot study on solar PV integration for BESCOM won a SKOCH Silver Award in the Technology category.

CSTEP was recognised as an Institute of Repute by the Ministry of Environment, Forest and Climate Change (MoEFCC) for its contributions to improving air quality in Bengaluru. It launched the CSTEP Rooftop Evaluation for Solar Tool (CREST) to help Bengaluru residents and electricity distribution companies identify rooftops suitable for solar energy installations. CSTEP developed SiteRight, a decision-support tool designed to identify low-impact locations for renewable energy projects. The Government of Karnataka formally adopted SNEHA to monitor 37 lakh children and 7 lakh women across over 65,000 Anganwadi Centres statewide.

The Patna Clean Air Action Plan (PCAAP), developed by CSTEP, was approved by the Bihar State Pollution Control Board (BSPCB). CSTEP launched the first edition of the India Clean Air Summit (ICAS), a flagship event that brings together experts, policymakers, and civil society to tackle India’s air pollution crisis with science-based solutions. It conducted SAFARI (Sustainable Alternative Futures for India) modelling studies to explore sustainable development pathways aligned with the UN Sustainable Development Goals (SDGs). As a member of the GHG Platform India, CSTEP contributed to estimating India’s greenhouse gas emissions from the energy sector.
