In this post,  we start by making a review of the importance of taking action on climate change. We continue by presenting data that helps to understand the impact that the transportation sector in North America, and particularly freight transportation, has on climate change. Finally, we explain one of the strategies that can be applied in the freight transportation sector to help cutting greenhouse gas emissions to the atmosphere: Freight consolidation.

 

 

Real action on climate change is imperative

Real action on climate change is crucial. “The UN estimates that the world would need to increase its efforts between three- and five-fold to contain climate change to the levels dictated by science – a 1.5°C rise at most – and avoid escalating climate damage already taking place around the world.”

According to United Nations Secretary-General António Guterres, “The best science, according to the Intergovernmental Panel on Climate Change, tells us that any temperature rise above 1.5 degrees will lead to major and irreversible damage to the ecosystems that support us”. In fact, “Science tells us that on our current path, we face at least 3-degrees Celsius of global heating by the end of the century. ”.

 

North America occupies first place in the world ranking, although with a negative note: 20.8 tons of CO₂ emissions per capita in 2019, the region formed by the US and Canada is the one that contributes the most to the change climate with its inhabitants on a personal level by a wide margin.

 

 

Environmental impact of freight transport

Increase in concentrations of greenhouse gases (GHGs) in the atmosphere causes the Earth’s atmosphere to warm, which results in climate change. Examples of greenhouse gases are methane, nitrous oxide, hydrofluorocarbons, and carbon dioxide. Cars and Trucks burn fossil fuels like gasoline and diesel, releasing carbon dioxide, a greenhouse gas, into the atmosphere.

 

Land transportation accounts for 62% of emissions. In terms of road freight, it is a rapidly growing sector, partly due to the rise of e-commerce and home delivery. And it is the most difficult transportation segment to decarbonize, since the use of clean energy is much less developed than in people transportation. That is why more and more companies seek to reduce their carbon footprint through sustainable and efficient transportation practices

  • In 2021, Mexico’s gross Greenhouse Gas (GHG) emissions amounted to 714 million tons of CO2 equivalent, contributing 1.4% of the global total

 

 

Benefits of reducing CO2 emissions in freight transport

Benefits for the environment: By reducing the amount of CO2 emitted, the impact of transportation on the environment is reduced, improving air quality and reducing the carbon footprint.

Benefits for companies: Reducing CO2 emissions can also generate significant savings in transportation costs and increase the efficiency of logistics operations, improving market competitiveness and at the same time brand image.

Benefits for customers: By implementing sustainable transportation practices, companies are perceived as socially responsible and committed to protecting the environment, gaining recognition and achievements at the state and global level, entering new market categories.

 

 

 

Optimize transportation logistics

One of the most effective strategies to reduce CO2 emissions in freight transportation is to optimize logistics and route planning.

Being more efficient, they reduce time on the road and, consequently, reduce fuel consumption and CO2 emissions.

Along with reducing transportation costs, efficiency in logistics operations is increased and the carbon footprint is reduced, the efficiency of the company’s logistics operations improves, which can translate into significant cost savings and a significant improvement in productivity. the brand image in terms of ecology and sustainability.

 

 

 

Use efficient driving practices

Driving style can also significantly contribute to reducing CO2 emissions in freight transport.

This is achieved through efficient driving practices such as reducing speed, reducing the weight of transported loads, and proper vehicle maintenance.

 

 

 

Reducing Carbon Pollution from Freight Transportation: Freight consolidation

The Environmental Defense Fund (EDF) has identified strategies to cut GHG emissions and local air pollution while driving business value. One of those strategies is “Getting the most of every move”.

Fuller truckloads are more environmentally friendly and have more business value. However, “15–25 percent of U.S. trucks on the road are empty and, for non-empty miles, trailers are 36 percent underutilized.”, explains Homayoun Taherian in his article Co-loading  your way to green.

And, “Capturing just half of this under-utilized capacity would cut freight truck emissions by 100 million tons per year – about 20 percent of all U.S. freight emissions – and reduce expenditures on diesel fuel by more than $30 billion a year”1

 

 

 

Freight consolidation to reduce CO2 emissions that cause climate change

 

 

Freight consolidation helps to reduce the percentage of truck underutilized and cuts freight truck Greenhouse gas emissions. Freight consolidation is a freight transport service in which several loads,  all of them being forwarded to the same location, are shipped together in a Truck.

Greenhouse gas calculation for North American Freight

The  Center for Transportation and Logistics of the Massachusetts Institute of Technology, offers the formula for the greenhouse gas calculation.

D x W x EF

Where:

D= The distance  your shipment has traveled

W= The weight of the shipment

EF = The mode’s specific emissions factor from the Environmental Defense Fund chart.

The weight-based truck emissions factor is 161.8 because the average freight truck in the U.S. emits 161.8 grams of CO2 per short ton-mile.

 

 

 

Example: Calculating emissions from truckload move from Montreal  to Laredo

Formula= D x W x EF

Distance= 2,184.6 miles from Montreal to Laredo

Weight= 22 short tons, which is the maximum weight admissible for a 53ft Dry Van.

EF= 161.8 (161.8 grams of CO2 per short ton-mile)

Calculating:

2,184.6 miles x 22 short tons = 48 048 ton-miles

48 048 ton-miles x  161.8 grams of CO2 per ton-mile = 7 774 166.4 grams of CO2

7 774 166.4 grams of CO2 = 7.77 metric tons of CO2 for this move.

Therefore, a Dry Van going from Montreal to Laredo at its maximum weight capacity accounts for  7.77 metric tons of CO2.

How freight consolidation reduces the amount of CO2 emissions

Freight consolidation reduces Greenhouse emissions to the atmosphere example

 

 

 

 

Imagine there are three shippers sending freight from Montreal to Laredo.

  • Shipper A sends a load of 10 tons
  • Shipper B sends a load of 4 tons
  • Shipper C sends a load of 5 tons

As we said,  a Dry Van going from Montreal to Laredo at its maximum weight capacity accounts for  7.77 metric tons of CO2.

On one hand,  if each of these shippers ships its freight separately in a 53ft Dry Van,   each shipper would account for 7.77 metric tons of CO2, a total of 23.1 metric tons of CO2.

On the other hand, Mexicom Logistics can consolidate the 3 shippers freight at its  Consolidation center in Montreal and use only one 53ft Dry Van for the 3 loads, reducing the emissions of CO2 from 23.1 metric tons of CO2 to 7.77 metric tons of CO2 for the three shipments.  Also,  every shipper  would reduce its CO2 emissions  in the following proportion:

  • Shipper A, which sends a load of 10 tons, reduces its CO2 emissions from 7.77 metric tons of CO2 to 3.5 metric tons of CO2 by using a freight consolidation service.
  • Shipper B, which sends a load of 10 tons, reduces its CO2 emissions from 7.77 metric tons of CO2 to 1.41 metric tons of CO2 by using a freight consolidation service.
  • Shipper C, which sends a load of 10 tons, reduces its CO2 emissions from 7.77 metric tons of CO2 to 1.76 metric tons of CO2 by using a freight consolidation service.

 

 

 

Route and Load Optimization

Optimizing routes and cargo is key to reducing the environmental footprint of freight transportation. The use of fleet management systems and geographic information technologies allows the most efficient routes to be planned, minimizing the distances traveled and reducing polluting gas emissions. Likewise, cargo consolidation and efficient use of space in vehicles help maximize cargo capacity and reduce the number of trips required.

Promoting awareness and environmental responsibility in cargo transportation is essential. Companies should adopt policies and practices that promote sustainability, including staff training, adoption of environmental certifications and standards, and transparency in the disclosure of information related to their environmental performance. Furthermore, it is important to foster collaboration between stakeholders, including governments, companies and civil society, to promote joint solutions and promote a culture of sustainability in the sector.

It is essential that companies, governments and society as a whole commit to taking concrete measures to mitigate the environmental impact of freight transport and work towards a more sustainable and environmentally friendly future.
