Agriculture is a one of the largest sources of C02 emissions.
Mellac contributes to their reduction by using organically
farmed products whose carbon footprint is 30% less than
that of conventional agriculture. The city reached a weight
figure of 26% organic products during the abovementioned
period, i.e., nearly five metric tons.
The Mellac local government maintains a school cafeteria
that feeds 200 children at lunchtime. The weight of fermentable
wastes is estimated at five metric tons annually.
Six 800-liter composters reduce organic waste incineration
at Concarneau, 30 km from Mellac. The first composters
have been cleared and [fertilizer] has been used in area family
Five municipal buildings are natural-gas heated. The municipal
government decided to reduce consumption via
the application of a more economical regulating and circulating
appliance as well as by double-glazing a previously
unequipped room. The reduction reached 12% between 1
September 2011 and 2012, i.e, 55,000 fewer kwh and a
ten-metric-ton reduction to greenhouse atmospheric emissions.
