<aside> 💡 High-Level Description:

The Department for Environment, Food & Rural Affairs (DEFRA) of the UK has been at the vanguard of introducing environmentally-conscious standards and methodologies across various sectors. With the transportation sector being a significant contributor to greenhouse gas emissions, DEFRA's focus on bus transport has been both strategic and timely. Buses, especially in urban settings, serve as a pivotal mode of mass transportation, making them crucial targets for emissions reductions and sustainable practices.

DEFRA's methodology for the bus sector meticulously examines the lifecycle emissions of buses, factoring in aspects such as manufacturing, operation, and eventual decommissioning. It also takes into account the environmental impacts of various fuel types, including diesel, electric, and hybrid. The goal is not only to ascertain the current emissions but also to provide a roadmap for bus operators, manufacturers, and policymakers to develop greener alternatives and operational practices.
