VWTB CTO Rodrigo Chaves on cutting truck CO2: match biofuels, electric and hybrid to each market's energy matrix
Volkswagen Truck & Bus CTO Rodrigo Chaves says cutting transport CO2 is not about one perfect global technology but about matching biofuels, electrification and hybrids to each market's energy reality.

What Happened
Rodrigo Chaves, CTO R&D and Board Member at Volkswagen Truck & Bus (VWTB), argues that reducing the CO2 footprint of transport isn't about finding one perfect global technology, but about matching the right solution to each market's energy reality. He has spent nearly three decades turning technology into real-world impact, starting at the Brazilian Navy Research Institute and later leading powertrain development across TRATON in Sweden. Today he is helping shape a pragmatic, energy-matrix-led path to CO2 reduction in which biofuels, electrification and hybrid solutions each play their part.
Joined Volkswagen, which was restarting its plants after the end of its joint venture with Ford and had to rebuild everything.
The TRATON GROUP had three companies – Scania, MAN and Volkswagen Truck & Bus (then called Volkswagen Caminhões e Ônibus) – and Chaves helped create common ground so their teams could connect and trust each other.

- Up to 90% lifecycle CO2 reduction versus regular fossil diesel, depending on feedstock and production process
- 80% to 90% lower carbon intensity than fossil alternatives, depending on the type of biofuel
- Zero tailpipe emissions
- Cities: very high population density and much better electric infrastructure than the countryside, so existing battery technology plus overnight recharging supports a comprehensive truck and bus operation with shorter payback, zero tailpipe emissions, better air quality and lower noise.
- Long-haul: electrification will take time to develop in terms of infrastructure and fast-charging stations, so Chaves expects a transition with hybrid solutions.
- Agribusiness and refuse collection: biomethane can be produced from agribusiness as well as garbage and refuse, letting operators use existing technology for a large CO2 reduction before going to electrification.
“We had a common goal: to create a positive impact, to exchange, to learn with each other.”
Under the TRATON Modular System, the group is developing a new global heavy platform, collecting all global requirements through extensive discussion of properties and cost. Each brand takes leadership on specific matters: VWTB focuses on cost-optimized solutions, MAN and Scania bring deep know-how in technology development, vertical integration and aerodynamic efficiency, and US colleagues contribute strongly on customer centricity. Chaves says matching four different points of view brings both technical and cultural challenges and takes time, but he is confident the team will find a way.
Previously from TRATON Group
TRATON's own newsroom has been leading with e-mobility, modular powertrains and supply-chain topics, opening its Stories page on buses heading into an electric future. In Brazil, Scania's sustainability chief Patricia Acioli has argued that meaningful change starts with listening to communities rather than grand gestures.

Why this matters
Trucks and buses are hard to electrify everywhere at once, and Chaves says the answer depends on each region's energy mix. In Latin America that means existing biofuels and biomethane can cut lifecycle CO2 now, while cities with better electric infrastructure move to battery-electric trucks and buses. Fleet buyers, city residents facing air-quality and noise problems, and regional agribusiness are all affected.
