Welcome on piarc.org!

PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

  • Asset Management in the Context of Climate Change - Approach of the Bavarian Road Administration

    Transport and road transport in particular, is and remains the biggest ‘CO2 polluter’ in Germany and in Bavaria as well. Looking at Bavaria’s total Greenhouse gas (GHG) emissions compared to global emissions, Bavaria was only responsible for 0.2%, Germany for 1.8% of global GHG emissions in 2022. However, this does not absolve Bavaria and Germany from their responsibility to curb the causes and consequences of climate change. The Federal Republic of Germany has set itself legally binding national [...]

  • A Comparison of Rail and Road Transport as a Strategy to Reduce GHGs in Mexico

    Freight transport in Mexico has grown significantly since the North American Free Trade Agreement (NAFTA, now T-MEC) entered into force, bringing with it direct and indirect environmental consequences in the country’s main transport corridors.

  • The Electric Road: Technical, Economic and Environmental Study Carried Out in France

    The EU has ambitious targets to reduce by 40% GHG emissions from road transport by 2030 compared to 1990, then by -55% (Fit for 55), and to reach the carbon neutrality in 2050. Transportation represents 25% of the CO2 emissions in the world, among them 75% from road transport and 40% from freight transport. In the EU, 80% of passengers and 70 to 85% of inland freight transports are on the roads. Decarbonising road transport and fulfiling the CO2 reduction require all achievable solutions, above [...]

  • A Digital Tool to Support Decision Makings and to Reduce Carbon Footprint of Road Networks

    Roads are a material-intensive system with an ever-increasing material demand as evidenced by 700,000 km of new roads built around the world every year. Moreover, its particularly long service life of several decades implies maintenance needs with additional materials and energy consumption to secure vehicle safety and transport comfort. Meanwhile, climate actions and sustainable strategy in the infrastructure sector are of crucial importance to reduce material resource, energy consumption and associated [...]

  • Development of Solar Pavement in Japan and its Contribution to Carbon Neutrality

    In road paving, solar pavement is being developed worldwide against the backdrop of the Paris Agreement, which set a long-term goal of mitigating climate change by 2050 and beyond, SDGs, carbon neutrality and other initiatives. In addition to providing traveling space, pavement, which covers a certain size of surface area in cities and regions, has the potential to generate new values to create renewable energy. We are developing solar pavement with the aim of developing road paving technology that [...]
