Drivers lead the way in cutting greenhouse gas emissions.

All over Ireland people have pledged to keep to


as their top speed to combat climate change.

 One Billion drivers around the world could cut a billion tonnes of CO2

just by slowing down!

The biggest contribution you can make as a driver, to cut your greenhouse gas emissions, is to keep to 80km/hr

as your top speed on all roads.

Join the movement to cut road transport's emissions by a third.

Fill out form and we will put you on the map (see below).

If you would like stickers for your back window to show people what you doing we will send them to you for just €5

(100% goes to printing and promotion of the campaign).

People all over Ireland and beyond have made the pledge to cut their car emissions.


Oak trees take more carbon dioxide out of the atmosphere in Ireland than any other. Plant one today.

What happens when you slow down to 80 km/hr as your top speed?


Immediately you will dramatically cut your emissions:

Because wind resistance intensifies the faster you go, more and more  power with less and less gain in speed is needed for every 5km speed you increase beyond the optimum of 80km/hr. 


Effects on air quality:

Transport has important effects on air quality. Road traffic is connected to the emissions of PM10 (particle matter) and NOx (nitrogen oxides). As with CO2, the emission of these particulates will decrease when a lower speed is established. However, there will be an even greater decrease than for CO2. The reason for this is that at higher speeds and larger driving dynamics the emission of PM10 and NOx increase faster than fuel consumption and CO2 emissions.

The Constant Travel Time Budget: 

In the longterm you will not only save money and emissions but you will also cut the distances you travel. This is due to the phenomenon known as The Constant Travel Time Budget. This simply means that we are prepared to only spend a certain amount of time in our day travelling. Averaged over the whole population it works out at around 65 minutes per day. With all the extra speed we have achieved, we still spend the same amount of time travelling as we did in the 1950s. We travel further but stick to the same amount of time.


So we may assume that if we cut our speed to a max of 80km/hr we will also cut our distances travelled. This will all be done unconsciously. 

The rise of better and faster means of transport has only resulted in covering longer distances and making more journeys rather than a decrease in time spent on travelling. We don't save the time we hoped to by travelling faster.

Smoother driving

With everyone's top speed at 80km/hr we will have smoother driving, less loss of power through acceleration and braking and a more relaxed driver at the end of the journey. The emotional triggers for feelings of inadequacy or competitiveness when someone passes you out are gone.
