Amazon has signed a carbon removal deal with the Good Rice Alliance to purchase carbon credits generated by Indian rice farmers, according to local reports.

The deal will reportedly see Amazon invest $30 million into the initiative and secure more than 685,000 carbon removal credits during the initial crediting phase.

The Good Rice Alliance is a subsidiary of German pharmaceutical and agrochemical giant Bayer, in collaboration with GenZero, Temasek, and Shell Nature-Based Solutions.

The Alliance works across India with more than 13,000 smallholder farmers to reduce methane emissions through providing training, field-level support, and financial incentives to switch to sustainable methods of growing rice.

Current methods of rice cultivation cause significant methane emissions due to the flooding of paddy fields, representing up to 10 percent of global methane emissions. Sustainable methods, such as adopting improved water management, could slash the amount of emissions, according to the Alliance.

India is increasingly becoming a hotbed for carbon removal projects, with both Microsoft and Google also inking deals in the country. Last March, Microsoft signed a 1.5 million ton purchase agreement over 30 years from a large-scale afforestation project in India. Following this in January, Google signed a 100,000-ton deal with Indian biochar firm Varaha.
