IIMB Carbon Footprint 2023

IIMB GREENHOUSE GAS INVENTORY - EXECUTIVE SUMMARY
Indian Institute of Management - Bangalore is the top B-School in India spread over a lush
100-acre campus. The premier institution prides itself on its esteemed faculty, students &distinguished alumni. The campus itself is no stranger to fame with sustainable stonearchitecture, 66 acres of green cover, long-standing trees, enriched biodiversity delighting
visitors’ eye.
SUSTAINABILITY INITIATIVES:Since 2010, IIM-B has implemented several sustainable waste management practices oncampus. This includes 100% segregation of waste, with dry waste being sorted into 15 to 17
categories and sent to authorized end-recyclers. Wet waste is effectively composted using
microbial culture, while the biogas plant installed on campus converts food waste to biogas,
which is utilized for cooking purposes. Additionally, garden waste also undergoes
composting, enriching the soil nutrient levels across the campus.
Furthermore, IIMB has adopted rainwater harvesting measures, collecting rainwater fromrooftops and open wells. This harvested rainwater is subsequently utilized for activities suchas washing and flushing. To augment the groundwater table in and around the campus, 57
artificial recharge pits have been strategically excavated. These pits play a crucial role infacilitating water recharge and increase groundwater resources.
These initiatives have not only contributed to significant reduction in Institution’s carbon
footprint, but also enhanced water recycling and availability of freshwater resources.
Installation of solar panels at various building rooftops has directly contributed towards a
13% reduction in emissions.
INVENTORY METHODOLOGY:
To augment the initiatives that have shaped the campus so instinctively sustainable, IIMB has
chosen to determine their ‘Institutional Greenhouse Gas Inventory & Carbon stocks
assessment’.

EcoMorphosys Consultants are engaged to carry out
Greenhouse Gas Inventory. The studies are in line withguidelines set by Greenhouse Gas Protocol – Corporate
Accounting & Reporting Standard; ISO 14064 1:2018 Specification with guidance at the organizational level for quantification and reporting ofgreenhouse gas emissions and removals; complemented by Global Reporting Initiative (GRI)& World Business Council for Sustainable Development (WBCSD).

BOUNDARY & SCOPE:
IIM-B has extensively studied their organizational structure, operational boundaries &operational context while choosing the inventory boundary across all three Scopes ofemissions.

As represented, the boundary includes academic buildings, hostels, Centers of Excellence,resident quarters, all leased food outlets, horticulture & all categories of waste generated
during operations at IIM-B Bannerghatta campus.

While various Institutions & Global Corporations typically focus on quantifying their Scope
1 & 2 emissions alone, IIMB has gone a step further by delving into Scope 3 emissions toenhance relevance & completeness. Under Scope 3 emissions, we have quantified emissions
from every vehicle entering our campus – guests, employees, students, delivery; We have also
accounted for emissions resulting from our waste generation and the goods we purchase,among other factors.
CARBON SEQUESTRATION:
Beyond the bounds, this study has estimated the 66 acres of tranquil green cover at IIMB thatstocks carbon. The carbon sequestration study was carriedout in identified carbon pools in trees and shrubs. Carbon isstored through – Above ground biomass carbon (trees,trunk, leaves), below ground biomass carbon (roots), litterand deadwood biomass carbon, and soil organic carbon.
Apart from advantages of Carbon Stock potential, the green
cover in IIMB campus contributes to their surrounding
environment and ecosystem services such as nutrient
recycling,

climateamelioration,

providingoxygen,conserving water resources, improving air quality,preserving soil, and supporting wildlife habitat.

The report reveals that IIMB’s total carbon emissions, which includes scope 1, scope 2 andscope 3 emissions, for the reporting period 2022-23 were estimated at 3382 metric tons of
CO2 equivalent per annum which equals to about 1.44 metric tons of CO2 equivalent percapita.
IIM-B Green House Gas Inventory Summary & Sources, as per GHG Protocol scopes, areincluded in the annex. The primary contributors to the carbon emissions are energy
consumption, purchased & capital goods, followed by transportation.

Installation of solar panels within the campus has directly contributed towards 13%
reduction in Scope 2 emissions. Various integral Sustainability initiatives have alreadycontributed to the reduction in carbon footprint of the campus.
Carbon Stocks Assessment:
A total of 12,529 metric tons of Carbon is sequestered by the tranquil
65.94 acres of green cover. The carbon sequestration study identifies
137 species across 13,000 plantations, exhibiting varying girth sizes.
Notably, the two largest trees in size & sequestration capacity are Ficus

benghalensis (Banyan tree) with girth diameter of 478 cm & 332 cm;
storing 4.9 tons & 1.8 tons of carbon, respectively.

CONCLUSION:
The publication of the Carbon Inventory Report marks a significant milestone for IIM
Bangalore, symbolizing its unwavering dedication to comprehensive development, academicexcellence, and environmental stewardship. The revealed findings not only serve as abaseline for monitoring progress but also shape the evolution of strategies in pursuit of theInstitute's enduring sustainability objectives.
