Projet climat et air pur dans les villes latino-américaines (CALAC+) (angl.)

The Paris Climate Agreement adopted in December 2015 provides a clear signal from countries towards reducing emissions and build resilience to climate change impacts within the transport sector.

Thanks to its management and technical expertise, Switzerland contributes significantly to the transformation of cleaner transport in Latin American cities, to achieve the reduction of short-lived climate pollutants such as black coal and greenhouse gas emissions, promoting the transfer of knowledge and experience with a North-South and South-South regional and international cooperation approach.

The overall objective of CALAC+ is to reduce harmful air pollutants in Latin American capitals through the deployment of soot-free engines in urban public transport and off-road machinery to protect human health and mitigate climate change.

The project pursues a vision of healthier and more sustainable cities that seek to reduce emissions of black carbon and other pollutants by encouraging a shift to soot-free, low-carbon city buses and off-road machinery.

Le projet

Soot-free and low-carbon buses

Ensure that emissions of ultrafine particulate matter, black carbon and greenhouse gases from urban public transport systems are significantly and sustainably reduced through technical assistance. Support to improve legal frameworks, environmental and transport regulations (at municipal and national levels), investment planning and institutional capacity building by creating conducive conditions to the establishment of soot-free and low-carbon technologies.

Incubators of urban policies for off-road machinery

Support the development of intelligent policies for a significant reduction of ultrafine particles, black carbon and greenhouse gases from off-road urban machinery (construction and industry sectors), emissions that are not yet regulated in Latin America, but which contribute strongly to poor air quality, negative impacts on human health and climate change.

Global knowledge management network

Sharing, both regionally (Latin America) and globally, a systematized experience on successful policies, cost-effective actions and technologies to reduce fuel consumption, air pollution and carbon emissions in the urban context. Good practices and lessons learned will be made available through existing networks and platforms, such as CCAC (Climate & Clean Air Coalition) and OECD. The creation of a roster of experts in Latin America is also envisaged to promote South-South and trilateral cooperation.
