BBIS is signing up (has signed up) to the EcoSchools programme. With the IPCC now declaring the science is 'unequivocal', it is time to consider not only what we teach but how we, as schools, behave. We are physical institutions, each at the centre of a community of people who have impacts on carbon emissions. How can we do our part to help achieve the global goal of halving CO2 emissions by 2030 and getting to zero by 2050?
