Frequently Asked Questions

  • What is carbon footprint calculation software?

    Carbon footprint calculation software is a program that helps companies and organizations calculate their carbon emissions. It uses algorithms to measure an organization's emissions from their daily activities, such as transportation, purchasing habits, heating and cooling, and electricity use. With the software, organizations and individuals can gain insight into their carbon emission profile and take steps to reduce their environmental impact.

  • Why do organisations and companies need to calculate their carbon footprint?

    Organizations and companies need to calculate their carbon footprint in order to better understand the environmental impacts of their activities, so that they can take action to reduce their environmental impact. It also allows them to demonstrate their commitment to sustainability initiatives and set realistic carbon reduction goals.

  • Why a carbon footprint calculation software need a certification?

    A carbon footprint calculation software needs a certification to ensure that it has been tested and verified to be accurate, reliable, and up-to-date with the latest information related to carbon emissions. Certification also serves as a way to demonstrate the software's commitment to sustainability and environmental responsibility.

  • What is net zero target?

    A net zero target is a goal set by an organization or government to achieve a balance between the amount of greenhouse gas (GHG) emissions it produces and the amount it removes from the atmosphere. This is often referred to as "net zero emissions" or "carbon neutrality." Achieving a net zero target typically involves reducing emissions through energy efficiency, renewable energy, and other measures, and offsetting any remaining emissions by investing in carbon removal projects or other offsetting mechanisms. Net zero targets have become increasingly popular in recent years as a way to address the urgent need to reduce global GHG emissions and limit the impacts of climate change. Many countries, cities, and companies have set net zero targets, with some aiming to achieve them as early as 2030 or 2040.

  • What is GHG Protocol?

    The GHG Protocol is a widely-used standard for measuring and managing greenhouse gas (GHG) emissions. It provides a framework and guidelines for organizations to measure and report their emissions, and helps them develop strategies to reduce their carbon footprint. The GHG Protocol was developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) and is used by businesses, governments, and other organizations around the world. The protocol covers three scopes of emissions: Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased electricity, heat, and steam), and Scope 3 (indirect emissions from the value chain, including suppliers, customers, and transportation).

  • What is Kyoto Protocol?

    The Kyoto Protocol is an international treaty signed in 1997 to address global climate change. It was adopted in Kyoto, Japan, and entered into force in 2005. The main goal of the protocol is to reduce greenhouse gas emissions from industrialized countries, which are primarily responsible for global warming. The protocol sets binding targets for these countries to reduce their emissions by a certain percentage below their 1990 levels. The protocol also establishes a system of emissions trading that allows countries to buy and sell emissions credits in order to meet their targets. The Kyoto Protocol is considered a landmark agreement in the global effort to address climate change, although it has been criticized for its limited scope and effectiveness in reducing emissions.
