Carbon dioxide removal market set to grow as firms look
for
offset opportunities
SINGAPORE, Jan 16 (Reuters) - Google will buy
carbon credits from an Indian initiative that turns large
amounts of agricultural waste into biochar - a form of charcoal
that removes carbon dioxide from the atmosphere and returns it
to the soil, it said on Thursday.
The deal - signed by Google and Indian supplier Varaha - is
one of the biggest ever involving biochar, and is the tech
giant's first foray into India's carbon dioxide removal (CDR)
sector.
Google is one of a number of big tech companies looking to
offset emissions through CDR, which refers to a range of
interventions designed to remove CO2 already in the atmosphere
and oceans.
While some developers are looking at expensive new
technologies that extract CO2 directly from the air, solutions
like biochar could prove a cheaper near-term option.
"Biochar is a promising approach to carbon removal because
it has the ability to scale worldwide, using existing
technology, with positive side effects for soil health," said
Randy Spock, Google's carbon removal lead.
Varaha will buy waste from hundreds of smallholder farms in
India and build reactors to convert it into biochar, which can
sequester CO2 for hundreds of years. It will also be supplied to
farmers as an alternative to fertilisers.
Google will buy 100,000 tons of carbon credits from now
until 2030. Varaha's chief executive Madhur Jain said there was
scope for rapid growth, with waste from India's farms capable of
generating enough biochar to store more than 100 million tons of
CO2 every year.
CDR accounts for only a fraction of global carbon trading
but is expected to grow rapidly as countries and corporations
seek new ways to offset emissions.
However, critics say CDR is no substitute for emission cuts.
They also warn that solutions like biochar offer no guarantee
the CO2 will be removed permanently.
"We are going to face peak warming," said Jain. "Even if
something just reduces (CO2) or removes it for only 20 to 40 or
50 years, I feel that we need to do everything that we can."
