Overview

Genuine eco-tourism meets data-driven sustainability

Eco Lodge is a genuine eco-tourism property nestled in the biodiverse hills of Wayanad, Kerala. The resort features cottages built primarily with locally sourced bamboo, blended with modern comforts and traditional Kerala architecture. It actively involves local communities in operations, sourcing materials, food, and labour from nearby villages.

Guests enjoy immersive nature experiences amid the Western Ghats, with peaceful surroundings, wildlife proximity, and responsible hospitality. Wayanad ranks as one of India's top eco-tourism destinations, drawing travellers seeking rainforest treks, biodiversity, and low-impact stays.

Kerala's tourism sector has rebounded strongly, but competition is intense. Eco-conscious guests and B2B partners—including corporate retreat organisers, tour operators, and certification bodies—now demand clear proof of sustainable practices. Green claims without measurable data no longer suffice.

Eco Lodge was founded on strong environmental values with bamboo construction and local livelihood support. However, the management team lacked a structured system to assess, measure, and improve overall sustainability. Build to Sustain deployed its proprietary Sustainability Index Metric (SIM) to evaluate performance across 12 categories, delivering a clear baseline score, identified gaps, and an actionable roadmap.

Problem Identification

ESG gaps threatening competitive position

Before intervention, Eco Lodge operated with genuine intent but faced fragmented and unmeasured sustainability practices. The SIM assessment uncovered specific weaknesses across ESG dimensions.

Environmental Challenges

  • Energy Inefficiency: No double-glazed windows on at least 10% of windows, increasing heat transfer and energy demand. Passive cooling/heating design elements were under-utilised. Major appliances lacked Energy Star certification.
  • Limited Renewables: Only 0-10% of electricity came from renewables. No renewable backup power or formal energy management system. Indoor lighting was not consistently energy-efficient.
  • Water Management Gaps: Rainwater harvesting existed, but recycled/greywater systems for landscaping or flushing were absent. Wastewater recycling was not implemented, leading to higher freshwater consumption in a region prone to seasonal water stress.
  • Materials & Waste: Use of low-VOC paints was incomplete. Recycled construction materials were below best-practice levels despite bamboo use. Waste diversion from landfills was not maximised. Some areas lacked full composting.
  • Biodiversity: Preservation plans existed but were not fully active across all operations.

Social Challenges

  • Employment Gaps: While local skilled persons were employed, the percentage in full-time and part-time roles fell short of top benchmarks. Women's involvement could be expanded for greater inclusivity.
  • Community Support: Support for broader social causes and nature conservation programs was ad-hoc rather than systematic.
  • Transport Limitations: Bicycles were available, but carpooling, shuttle services, and EV charging infrastructure were missing. Distance to public transport scored moderately.
  • Indoor Environment: Good daylight and windows in parts, but fresh air exchange systems and air filtration were not fully optimised, affecting guest and staff comfort.

Governance Challenges

  • No Certifications: No formal sustainability certifications (LEED, GRIHA, IGBC, EDGE, BREEAM, etc.) were in place. This reduced credibility with B2B partners and certification-seeking clients.
  • No Tracking System: No centralised system to track, score, or report sustainability performance. Practices relied on good intentions rather than data and continuous monitoring.
  • Documentation Gaps: Awareness of GHG emissions and carbon-reduction practices existed but lacked documentation and integration into operations.
  • Inconsistent Enforcement: Waste collection frequency, segregation systems, and eco-friendly cleaning products were not uniformly enforced or measured.
Solution Implementation

SIM framework: practical, India-focused assessment

Build to Sustain implemented a targeted, practical solution using the Sustainability Index Metric (SIM) framework. The approach was collaborative, non-disruptive, and tailored to Indian eco-lodges with clear tools, local benchmarks, and an actionable roadmap.

Environmental Solutions

1
Design & Energy Optimization

Energy Star appliances, renewable backup systems, energy management implementation, and renewable electricity percentage improvements. Quick wins included expanding energy-efficient lighting to >90% and planning renewable integration.

2
Water Conservation Systems

Implementation guidance for installing greywater systems for landscaping and flushing, reducing freshwater consumption and addressing seasonal water stress concerns.

3
Materials & Waste Management

Structured waste segregation system using colour-coded bins for proper separation at source. Small-scale incinerator for safe disposal of non-recyclable dry waste, reducing landfill dependency.

4
Greenery & Ecology Enhancement

Tree cover percentage targeting >25%, vegetation preservation with native plants, active biodiversity plans, and landfill diversion. Built upon existing bamboo and green areas to strengthen ecological integration.

Social Solutions

5
Community & Employment Enhancement

Increased engagement of women and local skilled workers in full-time and part-time roles. Formalised support for community social causes with structured programs rather than ad-hoc initiatives.

6
Sustainable Transport Options

Expanded transport options by adding EV charging stations, shuttle services, and carpooling arrangements to reduce emissions and improve guest accessibility.

7
Indoor Environment Quality

Improved humidity control systems, ensured adequate windows for natural light and ventilation in every room, and optimised guest space allocation to enhance comfort and well-being.

Governance Solutions

8
Formal Sustainability Monitoring

Implemented structured sustainability monitoring system using the SIM tool for regular tracking and reporting. Developed phased action roadmap with clear timelines, responsibilities, and targets.

9
Certification Pathway

Pursuit of relevant sustainability certifications such as GRIHA, IGBC, or EDGE to enhance credibility with B2B partners and guests. Integration of sustainability performance into daily operations and management reviews.

10
Transparent Documentation & Reporting

Established transparent documentation and reporting mechanisms to support future audits and stakeholder communication, enabling confident communication of achievements.

Results

Strong, measurable improvements across ESG

The SIM assessment produced strong, measurable improvements that directly resolved the ESG gaps. Eco Lodge achieved an overall SIM Score of 8.13 out of 10.

Conclusion

From fragmented practices to high-performing sustainable operation

Eco Lodge has moved from fragmented practices to a well-governed, high-performing sustainable operation. With a robust SIM Score of 8.13, lower costs, reduced environmental footprint, stronger social contributions, and transparent governance, the property now exemplifies responsible eco-tourism in the Western Ghats.

Build to Sustain delivered this transformation through a straightforward, data-driven ESG approach using the SIM tool. What began as challenges in environment, social, and governance areas became measurable strengths.

Resource efficiency rose, costs fell, guest appeal increased, and the lodge gained a competitive edge in Kerala's eco-tourism market. The SIM Score provides an ongoing benchmark for continuous improvement.
