MAN attended the Rio+20 climate protection conference, where it took part in the debate about sustainable passenger and goods transportation and presenting eco-friendly technologies in the fields of commercial vehicles and energy. As an official partner of the international climate conference, which had around 50 000 participants, MAN provided 17 shuttle buses for the event.

MAN Latin America presented the first Brazilian truck with a hydraulic hybrid system at the MAN Group’s stand – the VW Constellation 17.280 6×2 Hybrid. The MAN Lion’s City hybrid, a city bus with an innovative diesel-electric hybrid drive, was also on show. This vehicle is already in use in many European cities like Barcelona, Paris and Munich.

Trucks powered by fuel based on sugar cane were also among the exhibits. MAN Latin America showcased the first model that can be run on either diesel or ethanol, namely the MAN TGS 33.440 6×4. The VW Constellation 17.190 runs on ultra-clean diesel, which is a renewable biofuel that contributes to the reduced carbon dioxide emissions of the vehicles.

One of the world’s leading providers of large-bore diesel engines and turbo machinery, MAN Diesel & Turbo offers core components for energy generation, especially for local power plants like those already supplied to Brazil. The engine technologies for power plants displayed at the climate conference guarantee fulfilment of the strictest emission standards. Their high fuel flexibility enables engines to be powered with different fuels like gas or biofuels. MAN Diesel & Turbo is also providing information on the use of compressors, such as the isolation and storage of greenhouse gases, as well as on the production of electricity using gas turbines and the use of steam turbines in solar power plants and waste-to-energy applications.
