High levels of carbon dioxide in the atmosphere collect and store so much heat that weather patterns change, temperatures rise, and other climate changes occur.

Nitrogen oxides (NOx) damages your respiratory system over time. It is also a component of acid rain which is harmful to vegetation and, as a consequence, animals.

Particulate matter are tiny particles that can damage your lungs and get into the bloodstream, reaching your heart and brain and increasing your risk of heart attack and, possibly, stroke and dementia.

Next Steps

Switch to an EV Switch to a cargo bike Benefits of walking and cycling

Zero- and low-emission vehicles (ZLEVs) can reduce your fuel and running costs and are exempt from London’s Congestion Zone, Toxicity-charge (T-charge) and Ultra Low Emission Zone charges. Organisations can contact CRP for help transitioning to ZLEVs.

Cargo bikes are a fun way for individuals to run errands while getting in some exercise. For businesses, in addition to a zero- or low-emission way to receive or deliver goods, using a cargo-bike can be more efficient and quicker than a car or van – especially within London. Organisations can contact CRP for advice on how to try or buy cargo bikes.

Walking briskly for just ten minutes every day is good for us. Walking burns calories, reduces stress, and boosts your mood and energy levels. Cycling, like walking, is suitable for nearly all fitness levels with the same health benefits. It is also a quicker way to get around while reducing your travel costs. NHS has more information available on the benefits of walking and cycling, as well as how to get started.

CRP’s Clean Air Route Finder can help you find walking and cycling routes with a lower exposure to harmful air pollutants.


The Clean Air Tool aims to help users better understand the impact of switching from a diesel van to a cleaner mode of transport by calculating and visualising their emission savings.

Cross River Partnership calculated the potential reduction of carbon dioxide (CO2), nitrogen oxides (NOx) and particulate matter (PM) emissions based on switching from a diesel van using U.K. fleet average emissions1, an assumed average vehicle speed2, and the average trip length within Greater London3 .

Working with a climate change consultant, we selected scenarios that are easier to visualize and calculated conversion factors for each emission type.

It is not possible to cover all sources of emissions, and several assumptions have been made in creating the conversion factors. Therefore, the results from the calculation tool are only to serve as a gauge, rather than a precise calculation. The methodology will be updated on an ongoing basis. If you have further questions, please contact CRP.

The Clean Air Tool was developed as part of Clean Air Villages 3 (CAV3) funded by the Department for Environment, Food & Rural Affairs (Defra). The CAV3 partners included 12 boroughs and 4 business improvement districts.
