The postal sector is significant in its role as a contributor to urban air quality issues. Simultaneously, operators must meet the needs of ever-growing e-commerce demand, which spiked significantly in 2020 during the COVID-19 pandemic, and is set to remain higher in the long term. Levels of air pollution in cities can sometimes reach toxic levels, hence a rapidly changing regulatory environment. In this climate, it is therefore crucial that we address our contribution to healthy urban spaces.

‘Emissions to air’ in the context of our programme refers to NOX, SOX, and particulate matter, and excludes carbon dioxide. ‘Air quality’ and ‘air pollution’ refer to the impact of these emissions specifically. By addressing air quality separately to climate change and resource efficiency, we are emphasising the consequences of our operations on human health, as well as on the environment. 

Through measuring performance in this area, IPC members are actively contributing to the aims of UN SDG 11 – Make cities and human settlements inclusive, safe, resilient and sustainable. In an internal IPC survey in 2018, SMMS participants identified target 11.6, ‘reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management’, as a priority for the postal sector. Given the importance of these issues to our industry, we have separated out air quality from waste management, which is addressed in the Circular Economy Focus Area.

Emerging trends

This is an area of intense innovation, given the critical levels of air pollution in some of our cities, and the ever pressing need to improve efficiencies in the last mile. 

  • Lower emissions vehicles – one of the most popular and obvious solutions is continued investment in alternative fuel vehicles (AFVs). The SMMS group operates an impressive fleet of AFVs, the growth of which will be crucial for improving urban air quality. Read more about it in the Resource Efficiency section
  • Incentivisation of cycling and walking – our participants have also demonstrated a commitment to encouraging cycling and walking both in their operations and in their employees’ commute, through a range of initiatives and investments, such as Cycle to Work schemes and safety awareness training. 
  • City hubs – often tested on a small scale first, such as in a single neighbourhood, city hubs operate as more efficient urban delivery services. Lower emissions vehicles are often used as part of these initiatives, and we expect to see their adoption more widely in years to come. 
  • Collaboration – sharing space and time will be crucial to reducing the impact on urban air quality while meeting consumer needs. This will in many cities require public-private sector partnership. However, given this is such a fast-moving issue, it is envisaged that cities will also be able to learn from each other, as solutions are developed. 


The group scored 35.8% in the Air Quality Focus Area of the Sustainability Management Proficiency (SMP) questionnaire. Participants scored best in questions related to Measurement & Evaluation. This reflects posts’ efforts to monitor their rate of progression against KPIs, which is key to reducing negative impacts in the future. However, this area did score lowest out of the seven Focus Areas and we acknowledge there is room for improvement in this regard. 

Posts scored least well in the Disclosure & Reporting pillar of this Focus Area in the SMP questionnaire. As this is the first year of reporting in this area under the SMMS programme, we expect performance in this pillar to improve in future years. We also expect to see stronger performance in the areas of Strategy & Policy and Embedding as posts continue to evolve their approaches and implement new initiatives. 

Quantitative metrics are not reported for Air Quality this year, however some SMMS participants do report individually on their organisation’s quality performance as part of their corporate reporting. As we improve the coverage of data collection, we expect to report on this area collectively in future years.

Highlights of the group’s performance in 2019 include:

  • 12 out of 19 posts have workplace programmes in place to reduce last-mile air pollution, e.g. Eco-driving training
  • 10 posts operate smart city solutions, or initiatives involving cooperation and development with other stakeholders to improve urban air quality
  • 9 participants have a policy in place related to air quality and/or pollution that includes a commitment to performance improvement. 

IPC encourages posts to develop management of their contribution to air quality, such as participating in initiatives with government and NGOs that aim to improve air quality, particularly in urban areas, and  developing policies that include explicit frameworks for achieving objectives, in line with global best practice.
