Business leaders are calling for a goal of net zero emissions to be set at the UN Climate Change Conference COP21 in Paris this week. With 7% of global emissions coming from international freight transport, and growth in globalisation expected to increase such emissions nearly fourfold by 2050, the response from the logistics industry will be fundamental to meeting that goal. Yet for Freight Transport to achieve zero carbon, a key constraint is having good information all supply chain players can trust.
The Volkswagen saga shows how gaps in emission measurement standards or their application can shatter our faith in claims regarding emissions or fuel performance. Transport operators make a variety of statements about their environmental credentials, but how can freight buyers compare options with confidence?
A new non-profit, the Smart Freight Centre, is leading a collaboration of the world’s biggest shippers and transport companies to create a transparent, universal method of calculating logistics emissions along supply chains so people can make better decisions on how to move freight in the greenest way.
Data Drives Emissions Down
Transporters act in various ways to reduce energy use and emissions intensity across all logistics sectors to save money, reduce risk and meet growing customer demands for green transport services.
Good information is crucial for transporters to understand the real costs and benefits of potential emissions savings opportunities. It can be difficult to isolate gains produced by a single initiative given the amount of variables that affect fuel economy. Uncertainty about the environmental performance of alternative fuels and engine technologies is compounded by the lack of reliable case study information on their effectiveness for each transport mode. The integrity of external information sources relies on what exactly was measured, how and by who, and how the data applies to a specific task, the equipment configurations and local conditions.
In response, a growing number of collaborative groups are assessing technologies and practices that enable low carbon transport and share information on what works and what doesn’t.
Measuring the Whole Supply Chain
At a broader level we must consider a supply chain’s end-to-end profile. Measuring emissions from a train, truck, plane or ship is one thing, but allocating shares of those emissions to each freight item carried gets complicated across all legs of multi-modal freight movements criss-crossing the globe.
Online retail is creating exponential growth in single-item deliveries direct to homes and workplaces from worldwide sources. Growing consumer demand takes priority over the efficiencies of traditional logistics models, where bulk shipments via distribution centres to retail stores provide economies of scale for more energy- and emissions-efficient freight. Light commercial vans are the fastest growing traffic category in many countries, yet vans are second only to aircraft in energy consumed per tonne kilometre and generate over four times more CO2 per tonne-km than the average 44 tonne truck. This restructuring of supply chains affects the environmental footprint differently across geographies and logistics sectors.
Increasingly, freight buyers need to better understand the sources of logistics emissions along their supply chains, where freight can account for 25% or more of a product’s lifecycle emissions.
One Common Standard
The Smart Freight Centre hosts a collaboration of business and associated stakeholders creating a global framework for logistics emissions accounting. In 2014 they established the Global Logistics Emissions Council (GLEC) to develop a universal and transparent way of calculating logistics emissions across global multi-modal supply chains so that shippers and logistics providers can include carbon footprints in business decisions, alongside costs, time and reliability when selecting modes, routes and carriers.
GLEC will harmonise existing methods and address gaps to devise an assurance standard in freight logistics emissions that enables more accurate and reliable benchmarking and realistic emission reduction strategies. Its’ framework builds on:
- Greenhouse Gas Protocol
- US EPA SmartWay program
- European standard DIN EN 16258
- Aviation’s IATA RP1678
- Shipping’s Clean Cargo Working Group
To better understand how it will operate for both shippers and logistics service providers in real world supply chains, a series of case studies is underway to gauge the practical availability of data and how it can be used to optimise low carbon freight movements. By simplifying a complex business with a common standard everyone can use to compare green logistics options, people can confidently use good information to reduce both environmental impact and cost.
Towards Zero Carbon Transport
Achieving net zero transport emissions requires using less fuel in tonne-kilometre terms (a key energy productivity metric) and using the cleanest fuels that suit particular freight tasks. The unavoidable residual emissions can then be neutralised by purchasing carbon offsets based on precise and trustworthy emissions measurement.
As global freight emissions rise, a harmonised method for emissions accounting becomes increasingly necessary. Supply chain players large and small must have good emissions information to maintain competitiveness and prepare for the complexity of a carbon-constrained world.
Consultation workshops in the USA, Latin America, Europe and Asia are inviting public comment on the GLEC Framework, so download it to learn more. If you think about how this tool can improve your freight decision-making, you can help develop a logistics emissions methodology that assists Freight Transport to realise the net zero emissions goal.
