- 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 碳减排计划（CRP）一份公开文件，报告您的范围1、范围2和选定的范围3排放，并承诺实现净零。主要的英国政府和NHS合同须提供。More in the glossary, the SECR简化能源与碳报告（SECR）：要求大型公司和LLP在年度报告中公布能源使用和排放的英国法律。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.
