Delhi's air pollution is a classic case of environmental injustice

India's new tax on car sales is a step in the right direction, but can the country address the wealth and power imbalance driving the health disaster?

The news that India is introducing a new tax on car sales to help combat severe air pollution and congestion problems has unsurprisingly been decried by the country's car industry.

The chair of India's largest car manufacturer, Maruti Suzuki, says the tax "is going to hurt the industry, and will impact growth and affect job creation". Following the announcement, shares in Maruti Suzuki traded more than 5% lower.
