Twenty is Plenty. Lower speeds on roads where people live, walk and shop benefit everyone, particularly the old and young. People also feel less intimidated about cycling, and our car journey times are barely affected. The encouragement this gives people to choose active travel has enormous consequences for improved health, well being and air quality for everyone in Bristol.

We strongly support the city-wide 20mph areas and want these extended to every residential street in the Greater Bristol. We support a ‘Total Twenty’ approach where higher speeds limits are an exception, and only where there is protected Space for Cycling. There is an excellent website with all the evidence at Bristol’s Better at 20.

    20 mph and the Clean Air Zone

    Bristol City Councils 20 mph review finishes today. In this consultation, the potential of 20 mph to help meet the National Air Quality Objectives (NAQOs) for NO2 and PM10 emissions, for which Bristol exceeds, has almost completely been ignored. Instead, a Clean Air Zone (CAZ) has been proposed to tackle this as part of central governments Clean Air Framework. A CAZ would attempt to reduce air pollution by encouraging residents and businesses to purchase a

    7 Reasons Einstein would support 20 mph

    Please take a moment to respond to the Bristol 20mph Review Our lives fundamentally rely on energy. It puts food on our table, gets us to and from work, powers our offices and factories. The more we use, the more money it costs us. Our demand for it causes wars, our generation of it emits harmful gases. Almost every issue 20mph raises is energy related and the answer to each, along with many of our

    Bristol consulting on 20 mph speed limit

    Bristol are consulting on 20 mph speed limits in the city (20mph Limits Review). We believe the city-wide 'Total Twenty' approach has been good for walking and cycling, and the evidence supports this. We're concerned that the review seems to be wholly focussed on reversing this and allowing 30mph on many roads. There is almost no mention of eduction or enforcement measures to embed the change. We're asking everyone to respond to the review. There

  • Bristol's 20mph zones work and should be copied across Britain (please note, Bath)

    Bristol's 20mph zones work and should be copied across Britain (please note, Bath)

    Last month a review of Bristol's 20mph areas was published by UWE with coverage in local media (here, here and here). This adds to the growing weight of evidence backing city-wide lower speed limits (unlike a widely ridiculed 'report' from Bath and North East Somerset Council (BANES). UWE’s Bristol Twenty Miles Per Hour Limit Evaluation (BRITE) study found that, on average, speeds on more than 100 surveyed roads have reduced since the 20mph speed limits

  • 20mph in Bristol saves more than 4 lives a year

    20mph in Bristol saves more than 4 lives a year

    One of those lives saved could have been yours or a loved ones. We've campaigned for 20mph to be the default speed limit in Bristol for nearly 30 years and we welcome this report from UWE which also found an estimated cost saving of over £15m per year from the avoidance of fatal, serious and slight injuries. So why is Bristol City Council still forging ahead with a review of the 20mph rollout, when clearly

  • Induced Traffic and Traffic Evaporation

    Induced Traffic and Traffic Evaporation

    The recent debate on the proposed Callington "Relief" Road has brought the concept of "induced traffic" back into the limelight. And also the the related and much neglected evidence for "reduced traffic", or the delightful concept of "traffic evaporation". So what do these terms mean? Induced Traffic As car ownership and use have increased over the past 30 years the reaction to the pressure created by additional traffic demand has often been to increase the

  • Fighting for more air

    Fighting for more air

    On this website we previously covered the excellent BBC documentary Fighting For Air. At the end of the programme, viewers were informed they could use an air quality postcode checker, enabling anyone in the UK to see how their area faired on a simple scale of 1 – 6. However, we delved into this for some areas of Bristol already covered by local council monitoring and were not convinced by the results. The checker considers only

    Fighting for Air

    On Wednesday 10 January, BBC Two aired Fighting for Air, a documentary looking at how a local community in Birmingham, aided by a BBC team, set about tackling pollution on their local high street. The street could have been a number of shopping streets in Bristol, with almost identical debates on issues involved. The solutions put forwarded for reducing pollution were smoothing traffic flow by introducing green waves, replacing the parking bays with vegetation and
