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 減碳計畫（CRP）報告範疇 1、2 及部分範疇 3 排放並承諾淨零的公開文件。主要英國政府與 NHS 合約均須提交。More in the glossary, the SECR簡化能源與碳排放報告：要求大型公司與 LLP 在年報中公布能源使用與排放的英國法規。More in the glossary report and the VSMEThe EU's Voluntary Sustainability Reporting Standard for smaller companies: a short, set format for energy, emissions and other figures that EU customers, banks and investors ask their suppliers for.More in the glossary report. See the plans.
- Add-ons are extra jobs on top of a plan, each with its own price. Most businesses don't need any. See all add-ons.
