Google has announced five new sustainability initiatives in India covering rooftop solar, renewable energy, climate-smart farming, environmental research and artificial intelligence. The initiatives combine AI-based mapping, satellite technology, clean energy, agricultural technology and climate-tech support. 

Announced on September 10, the initiatives involve collaboration with solar companies, farmers, researchers, the Government of India and Indian startups. The programmes address challenges related to clean energy, methane emissions, water conservation, climate research and sustainable land use.

Google Expands Solar API to More Than 300 Million Indian Rooftops

The extension of Google Solar API to over 300 million rooftops in India is one of the most technology-immediate projects of Google.

Solar API is part of Google’s Earth AI and uses AI and imagery to generate insights about rooftop conditions and solar potential. Google says Solar API can now generate insights for more than 1.2 billion buildings globally, including 300 million rooftops across India.

For solar installers, the main advantage is remote assessment of a property’s solar potential without an on-site visit. Rooftop insights can help installers assess available space, create system designs and prepare proposals more efficiently, reducing the time and cost associated with physical site assessments.

The growth of Google coincides with the fact that rooftop solar in India is still being encouraged and given incentives by the policy. One of the factors that the company identifies to have contributed to the increase in the amount of rooftop solar in the country is the government incentives.

Indian solar companies are already using the technology in their operations. Solar Ladder uses Solar API data in its work to enable installers to create mobile proposals and eliminate the need to physically assess sites multiple times. Another partner of Google Solar API is OpenSolar which uses the data to simulate the conditions of rooftops and create system and financial proposals to customers.

Google Adds a 150 MW Rajasthan Solar Project With ReNew Power 

Google is also increasing its clean-energy purchasing in India by a long-term contract with ReNew Power to generate a 150 MW solar power station in Rajasthan.

Google will get the environmental attributes of clean electricity produced by the project under the agreement. According to the company, these attributes will be used to assist in dealing with electricity-related emissions throughout its value chain.

The agreement forms part of Google’s broader strategy to decarbonise its supply chain.  Although the company claims that it is still engaging its suppliers in direct discussions to motivate them to use clean electricity, direct procurement of clean-energy attributes can help address electricity-related emissions which cannot be directly attributed to a particular supplier.

The Rajasthan project marks Google’s second Scope 3-focused solar project in India. This is strategically important to the company due to the concentration of its suppliers to the Asia-Pacific region, which includes India.

The 150 MW project is not to be confused with the total capacity of the two Scope 3 oriented solar projects of Google in India. The two projects, Google says, will provide a total of 300 MW of new solar generation capacity.

It is significant: the new Rajasthan agreement implies 150 MW, and 300 MW is the total anticipated capacity of two projects.

Google Targets Rice-Farming Methane With Alternate Wetting and Drying 

Google’s partnership with Mitti Labs focuses on reducing methane emissions from rice cultivation while conserving water. 

The project is expected to help tens of thousands of smallholder rice farmers adopt climate-smart farming practices in Telangana. Its main innovation is Alternate Wetting and Drying (AWD), a water-management method whereby rice fields are not maintained in standing water. Instead, farmers periodically drain and reflood the fields. 

It is important since rice paddies that are constantly flooded may cause the soil to become oxygen-depleted which is a favorable environment to produce methane. AWD interferes with such conditions by periodically letting fields dry out. The approach is thus able to minimize methane emissions, and decrease irrigation needs.

Google says rice cultivation accounts for up to 12% of all methane emissions globally, highlighting the potential climate impact of changes to rice-water management.  The company estimates that, once fully implemented, the initiative could conserve billions of gallons of water across regional basins in India while maintaining crop productivity.

Participating farmers also have an economic aspect of the programme. The method used by Mitti will give direct payments to the farmers as they implement the water-management practice.

Google describes the agreement as the largest publicly announced purchase agreement to date for credits generated by reducing methane emissions from rice cultivation.

Mitti aims to have roughly 3 million tonnes of CO₂e in near-term warming impact using a 20-year Global Warming Potential (GWP20) measure, equivalent to 1 million tonnes of CO₂e when measured over the conventional 100-year period (GWP100). 

The difference lies in the time horizon used to assess warming effects. GWP20 measures warming over a 20-year period, while GWP100 uses a 100-year period. Because methane is relatively short-lived but has a stronger warming effect than carbon dioxide over shorter periods, methane reductions can have a greater calculated impact under GWP20.

Another significant aspect of the project is verification. Mitti Labs uses NASA-enabled satellite-based verification alongside its on-the-ground network to measure the project’s impact and support farmers as they adopt AWD. 

Google has also articulated its plans to manage the temporary nature of climate impact these methane-reduction credits. If Google uses these credits to counterbalance emissions, the company says they will either be matched against shorter-lived emissions in its own footprint or replaced with carbon removals as their atmospheric impact expires. 

The program thus integrates a farm related intervention, remote sensing, purchase of climate credits and direct involvement of farmers instead of depending on a carbon accounting system.

Google Expands Climate Technology Research Through the Manthan Platform 

Google is also increasing its Google Center on Climate Technology that was launched in February, in collaboration with the Office of the Principal Scientific Adviser to the Government of India.

The Center applies AI to environmental challenges and supports researchers and innovators developing solutions to climate-related problems.  From 77 applications, Google selected three inaugural projects based on technical merit and anticipated impact. The projects focus on green workforce training and low-carbon construction materials. 

The grants may fund various development phases such as ready-to-teach courses, original research and pilot projects.

Google is also adding two new areas of focus. 

Water stewardship

The new water-stewardship track is geared towards scalable technologies and management practices that can safeguard and preserve watershed resources as freshwater pressure mounts.

Waste and circularity

The waste and circularity track focuses on issues such as e-waste research, battery recycling and broader efforts to promote more circular use of materials and resources.

Google is soliciting proposals via the Manthan Platform, and indicates that successful and qualified candidates will be assisted to create data-driven solutions in these fields.

The Center thus expands the sustainability activity of Google beyond implementing the existing technologies. It establishes a pathway of research, human resource development, and pilot projects to transfer ideas at an earlier stage to their practical implementation.

Four Indian Startups Join Google DeepMind’s AI for the Planet Accelerator

The fifth initiative focuses on India’s climate-tech startup ecosystem through the first cohort of the Google DeepMind Accelerator: AI for the Planet. 

The programme includes four Indian startups, each using AI or geospatial technologies to address a different environmental challenge. 

Terrastack uses satellite and agricultural data to provide plot-level land intelligence for smallholder farmers. Its work demonstrates how Earth-observation data can be converted into plot-level insights to support agricultural decision-making. 

Varaha Climate works with smallholder farmers on regenerative agriculture and verified carbon credits, using remote sensing and AI to support verification and participation in climate programmes. 

Farmers for Forests uses geospatial technologies and AI-powered drones to support agroforestry and make carbon and biodiversity outcomes more measurable. The initiative reflects the broader use of Geo-AI and satellite models for agroforestry and biodiversity restoration. 

Climitra Carbon uses Geo-AI to verify the removal of invasive species and converts the resulting biomass into biochar, linking geospatial monitoring with carbon removal. 

What Google’s Sustainability Push Means for India’s Technology Ecosystem 

Combined, the five initiatives reveal some of the various ways in which technology can be factored into climate action.

The Solar API uses AI and imagery to automate a previously manual aspect of deploying residential solar. The ReNew Power deal is based on clean-energy procurement wherein it deals with electricity-related emissions through a complicated supply chain. The Mitti Labs partnership uses a farming-based intervention and a satellite-based measurement to address the issue of methane and water consumption.

In the meantime, the Center Climate Technology is a research-oriented entity, workforce development and new environmental technology, and the DeepMind accelerator provides up-and-coming climate-tech startups with access to advanced AI and technical assistance.

One of the similarities is the growing role of measurement and data. The Rooftop imagery can guide solar offers; satellite systems can aid in tracking agricultural practices; Geo-AI can aid land and biodiversity measurements; and research-based on data can be applied to water, waste and circularity issues.

The programmes cover various levels of the technology ecosystem-infrastructure and energy purchases, to individual farms, academic research and start-up companies. It makes the announcement more comprehensive than one clean-energy investment or AI programme.

Many of the environmental outcomes described by Google are estimates, projected impacts or commitments rather than results that have already been demonstrated at full scale. Their effectiveness will depend on implementation, participation by farmers and other stakeholders, project development, measurement and verification. 

Conclusion

Google’s latest sustainability initiatives in India combine five distinct approaches: expanding AI-powered rooftop solar intelligence, adding a 150 MW Rajasthan solar project with ReNew Power, supporting methane-reducing rice cultivation with Mitti Labs, expanding climate-technology research through the Google Center for Climate Technology, and supporting four Indian startups through the AI for the Planet accelerator. 

The common element is the use of technology to make climate solutions more measurable, scalable or accessible. From rooftop assessments and satellite verification to regenerative agriculture, clean-energy procurement and Geo-AI, the initiatives place data and artificial intelligence alongside conventional climate interventions. 

For India’s technology ecosystem, the announcement highlights an increasingly interconnected climate-tech landscape in which renewable energy, agriculture, environmental research, satellite intelligence and AI are being developed and deployed together.
