India's largest automobile manufacturer Tata Motors has announced its commitment to source 100 percent electricity renewable energy by joining RE100 – a global collaborative initiative of the world's most influential companies that are committed to sourcing 100 percent renewable power. Tata Motors is the second Indian company to join RE100 so as to work towards increasing corporate demand for renewable energy.

Announcing its association with RE100, Tata said "Our climate change policy aims to maximise the use of renewable energy in our manufacturing operations. Doing so will not only reduce our carbon emissions, but also lead to long-term financial savings."

Tata Motors, which currently sources around 8 percent of its electricity from renewable energy, has solar energy installations at three of its manufacturing plants in India.

"The RE100 movement shows that the transition to renewable energy is achievable and it offers a powerful network to support and celebrate businesses increasing their use of renewable power. Tata Motors is proud to join such an initiative," added the company.

There are now more than 50 companies in the RE100 campaign. The countries that are part of the initiative include Adobe, Alstria, Autodesk, Aviva, Biogen, BMW Group, BROAD Group, BT Group, Coca-Cola Enterprises, Commerzbank, DSM, Elion Resources Group, Elopak, Formula E, Givaudan, Goldman Sachs, Google, H&M, IKEA Group, Infosys, International Flavors & Fragrances Inc.(IFF), J.
