<aside> 💡 High-Level Description:

The UK's Department for Environment, Food & Rural Affairs (DEFRA) has long been at the forefront of environmental research and policy-making. Within the sphere of air freight, DEFRA has developed a distinctive methodology to address the sector's carbon emissions. Recognizing the complexities of modern global trade and the vital role of air cargo, DEFRA's approach incorporates a multitude of factors such as fuel type, cargo weight, distance traveled, and the associated ground operations.

Moreover, DEFRA's methodology goes beyond the mere calculation of emissions. It delves into the intricate interplay of logistical operations, aiming to offer recommendations for sustainable practices. This includes everything from optimal packaging to reduce weight and hence emissions, to the use of alternative fuels. With DEFRA's guidance, the air freight industry can identify areas of improvement and adopt strategies that align with global environmental goals.
