Notes to Editors

JLR’s Reimagine strategy is delivering a sustainability-rich vision of modern luxury by design.

We are transforming our business to become carbon net zero across our supply chain, products, and operations by 2039. We have set a roadmap to reduce emissions across our own operations and value chains by 2030 through approved, science-based targets. Electrification is central to this strategy and before the end of the decade our Range Rover, Discovery and Defender collections will each have a pure electric model, while Jaguar will be entirely electric.

At heart we are a British company, with two design and engineering sites, three vehicle manufacturing facilities, an engine manufacturing centre and a battery assembly centre in the UK. We also have vehicle plants in China (a joint venture), Slovakia, Austria (contract manufacturing with Magna Steyr), India (contract manufacturing with Tata Motors Ltd.) and Brazil, as well as seven technology hubs across the globe.

JLR is a wholly owned subsidiary of Tata Motors Limited, part of Tata Sons.
