Three kinds of thing

  • Free tools answer one question each, such as "do I need a Carbon Reduction Plan?". No account, no email. See all free tools.
  • A plan is the software itself: you add a year of bills, it works out your footprint in tCO2eTonnes of CO2e, the unit a carbon footprint is given in. One tonne is 1,000 kg of greenhouse gases, counted as if they were all CO2.More in the glossary and writes the reports. Every plan makes the Carbon Reduction Plan (CRP)Un documento público que informa de sus emisiones de alcances 1, 2 y de una selección del alcance 3, y le compromete con las cero emisiones netas.
