Reduce ruminant methane emissions via seaweed
Methane is a powerful greenhouse gas (about 30-70x CO2, depending on time-scale). Cow belching comprises the largest proportion of human-caused emissions. Studies have found giving a certain type of red seaweed to cows can reduce their methane emissions by up to 80%. RISC should partner with major agricultural companies and/or restaurant chains to pilot and further study the solution.
