However, there is still room for innovation, particularly in areas such as energy storage and integration with other vehicle systems. As governments worldwide push for stricter emissions regulations, regenerative braking is becoming a crucial component in achieving low-carbon transport goals.

The policy framework for low-carbon transport plays a crucial role in promoting sustainable mobility solutions and reducing greenhouse gas emissions in the transportation sector. This framework encompasses a range of regulatory measures, incentives, and guidelines designed to encourage the adoption of environmentally friendly transportation technologies and practices.

At the core of this framework are emissions reduction targets set by governments at various levels. These targets often align with international agreements such as the Paris Agreement and are translated into specific goals for the transport sector. To achieve these goals, policymakers implement a mix of regulatory and market-based instruments.

One key aspect of the policy framework is the establishment of vehicle emission standards. These standards set limits on the amount of carbon dioxide and other pollutants that vehicles can emit, pushing manufacturers to develop and produce more fuel-efficient and low-emission vehicles. Many countries have adopted increasingly stringent emission standards, with some setting ambitious targets for phasing out internal combustion engine vehicles in favor of electric and other zero-emission alternatives.

Financial incentives form another critical component of the low-carbon transport policy framework.
