  • What does Custos do?
    Custos leverages data intelligence to enhance corporate sustainability culture by establishing an infrastructure for collecting and analyzing data. Our focus is on implementing data-driven initiatives that encourage employees to take climate-friendly actions, leaving positive carbon handprints on the environment.
  • What is a carbon handprint? How is it different from a carbon footprint?
    A "carbon handprint" refers to the positive environmental impact or actions that individuals or organizations make to reduce or offset their carbon footprint. While a carbon footprint measures the total greenhouse gas emissions associated with an entity, a carbon handprint focuses on the positive contributions made to mitigate or balance those emissions. This can include activities such as energy conservation, adopting sustainable practices, or supporting initiatives that contribute to environmental sustainability. Essentially, a carbon handprint represents the positive mark left on the environment through eco-friendly actions.

  • What does carbon neutrality mean?
    Carbon neutrality is a state of net-zero carbon dioxide emissions. This can be achieved by balancing emissions of carbon dioxide with its removal (often through carbon offsetting) or by eliminating emissions from society (the transition to the "post-carbon economy"). The term is used in the context of carbon dioxide-releasing processes associated with transport, energy production, agriculture, and industry. Although the term "carbon neutral" is used, a carbon footprint also includes other greenhouse gases, measured in terms of their carbon dioxide equivalence. The term climate-neutral reflects the broader inclusiveness of other greenhouse gases in climate change, even if CO2 is the most abundant. The term net zero is increasingly used to describe a broader and more comprehensive commitment to decarbonization and climate action, moving beyond carbon neutrality by including more activities under the scope of indirect emissions, and often including a science-based target on emissions reduction, as opposed to relying solely on offsetting. Some climate scientists have stated that "the idea of net zero has licensed a recklessly cavalier 'burn now, pay later' approach which has seen carbon emissions continue to soar." Source: Wikipedia
  • In what ways can a sustainability culture positively impact a company's reputation and brand image?
    Cultivating a sustainability culture, which involves encouraging individuals and organizations to create more carbon handprints can significantly enhance a company's reputation and brand image. Firstly, it allows the company to differentiate itself and gain a competitive edge in a conscientious market, fostering loyalty and trust among customers. Secondly, embracing sustainability and promoting carbon handprints generates positive publicity, shaping the company as a responsible corporate citizen, enhancing public perception, and increasing brand recognition. Moreover, a sustainability culture aids in attracting and retaining top talent, especially among younger generations valuing socially responsible workplaces, and it enhances investor confidence by aligning with modern ESG criteria. The culture also acts as a risk mitigation strategy, preventing reputation-damaging incidents and building stakeholder trust. Lastly, it fosters collaborations, unlocking partnerships for shared sustainability efforts.
  • Are there any financial advantages or cost savings associated with integrating sustainability into employee lifestyles?
    Certainly, integrating sustainability into employee lifestyles can yield financial advantages and cost savings for organizations through various avenues. For instance, encouraging energy-efficient practices like powering down electronics and optimizing lighting can lead to reduced energy consumption, translating to lower utility expenses. Responsible waste management through using reusables, reduces procurement and lowers waste disposal costs. Embracing sustainable commuting options helps cut down on fuel expenses and parking fees, and adopting meatless meals lead to healthier liestyles while reducing food and healthcare costs. While the extent of savings varies, the potential for positive financial impacts through sustainable integration into employee lifestyles is substantial and beneficial for organizations in the long term.
  • How can companies encourage and incentivize employees to actively create more carbon handprint by adopting sustainable behaviors?
    Promoting and incentivizing sustainable behaviors among employees requires a comprehensive approach. Effective strategies include raising awareness through education, leading by example, fostering employee engagement through participation and leadership roles, offering incentives and rewards for notable carbon handprint achievements, incorporating gamification elements, maintaining open communication channels, optimizing workplace infrastructure, providing training, integrating sustainability into performance evaluations, and continuously improving sustainability initiatives that contribute to positive carbon handprints. By tailoring these strategies to the organization's culture, a robust framework can be established to encourage lasting sustainable practices among employees.
  • Can you provide examples of companies that have successfully integrated carbon handprint initiatives into their employee lifestyle programs? What were the outcomes?
    Several companies have successfully integrated carbon handprint initiatives into their employee lifestyle programs, yielding noteworthy outcomes: DBS Bank: DBS Bank has been recognized for its strong commitment to sustainability and has implemented various carbon handprint programs. They have initiatives like "DBS Green Day" and "DBS Eco-office" that encourage employees to adopt behaviors contributing positively to their carbon handprints, such as reducing energy consumption, promoting recycling, and minimizing paper usage. DBS Bank's efforts have resulted in significant energy savings, reduced carbon emissions, and increased employee awareness and participation in creating carbon handprints. Google: Google has implemented various sustainability initiatives, including employee lifestyle programs. For instance, they promote sustainable commuting options by providing shuttle services, bike facilities, and electric vehicle charging stations. They also incentivize employees to use public transportation or carpool through discounted transit passes and preferred parking spots. These efforts have resulted in reduced carbon emissions and traffic congestion, contributing to Google's overall carbon handprint goals. Unilever: Unilever launched its "Sustainable Living Plan" to embed sustainability into every aspect of its business. As part of this plan, they implemented employee lifestyle programs focused on reducing waste and promoting responsible consumption. Unilever provided employees with reusable water bottles, eco-friendly lunch containers, and encouraged sustainable commuting options. The company achieved significant waste reduction, lower carbon emissions, and improved employee engagement.
  • What are the key challenges organizations might face when trying to instill a sustainability culture among employees, and how can they overcome these challenges?
    When cultivating a sustainability culture among employees, meaning encouraging them to create more carbon handprints, organizations can encounter several challenges. Strategies to overcome these include building awareness through comprehensive programs, managing resistance with change management, securing leadership support, engaging employees actively, tracking progress effectively, integrating sustainability into workflows, and addressing cultural barriers by aligning goals with organizational values. By addressing these challenges strategically, organizations can foster a sustainable mindset and drive positive change throughout their workforce.
  • How can companies measure and track the impact of employee lifestyle changes on overall sustainability goals?
    Companies can measure and track the impact of employee lifestyle changes on overall sustainability goals through a structured approach. This involves defining specific sustainability metrics, establishing baselines for comparison, collecting regular data on energy consumption, waste reduction, transportation emissions, and other relevant indicators, analyzing the data to quantify changes attributed to lifestyle modifications, monitoring employee engagement in sustainability initiatives, and utilizing surveys and feedback to gain insights into employee experiences. By evaluating cost savings, conducting comparative analysis, and sharing success stories, companies can transparently communicate the positive outcomes of employee-driven sustainability changes to stakeholders and continuously refine their strategies.
  • Are there any potential risks or downsides to consider when implementing initiatives to change employee lifestyles for sustainability?
    While implementing initiatives to change employee lifestyles for sustainability offers numerous benefits, there are potential risks and downsides to consider: Resistance and Disengagement: Employees might resist or disengage from lifestyle changes, perceiving them as inconvenient or disruptive to their routines, which could undermine the effectiveness of the initiatives. Privacy Concerns: Initiatives that involve tracking employees' behaviors, such as commuting habits or energy usage, could raise privacy concerns and lead to distrust. Cultural Sensitivity: Lifestyle changes might not be suitable for all cultural backgrounds, potentially causing discomfort or misunderstanding. Negative Employee Morale: If not communicated effectively, initiatives might be perceived as punitive or overly restrictive, negatively impacting employee morale and engagement. Resource Allocation: Implementing and maintaining lifestyle change initiatives require resources in terms of time, finances, and personnel, diverting attention from other priorities. Short-Term Focus: Employees might only engage with the changes as long as they are incentivized, leading to a lack of long-term behavioral change once incentives are removed. To mitigate these risks, it's important to engage employees in the design and implementation process, offer choice and flexibility, provide clear communication about the benefits of changes, ensure privacy and data security, and continuously evaluate and adapt initiatives based on employee feedback and evolving circumstances.
  • Does taking stair instead of lift represent carbon emission reduction?
    Yes. Elevators require electricity to operate, which often comes from non-renewable sources such as fossil fuels. By opting for the stairs, you save energy and reduce the demand for electricity, indirectly leading to lower carbon emissions associated with power generation. While the impact of a single instance may be small, choosing the stairs consistently over time can collectively contribute to energy conservation and a reduction in carbon emissions.
  • How much carbon emission saving is achieve when I repair my phone instead of replacing it?
    A brand-new smartphone generates an average of 85 kilograms in emissions in its first year of use. Ninety-five percent of this comes from manufacturing processes, including the extraction of raw materials and shipping. After it is manufactured, a smartphone generates an average of 8 kilograms of emissions from usage during its working life, which is most commonly between two and five years. Because manufacturing accounts for almost all of a smartphone’s carbon footprint, the single biggest factor that could reduce a smartphone’s carbon footprint is to extend its expected lifetime.

  • What if I don't get a strong GPS signal?
    Make sure that GPS usage is enabled in Location settings and that your device has a clear view of the sky, away from buildings, trees, or other obstructions. It can sometimes take a minute or two for the device to acquire a strong signal from the satellites.
  • What if my data won't sync?
    Follow these instructions: 1) Force-quit (kill) the Custos app 2) Relaunch the Custos app If the problem still persists, please submit a support ticket and we will look into the matter and get back to you shortly.
  • What happens if the recorded data is wrong?
    Occasionally, GPS issues will cause an activity to be recorded incorrectly, leaving gaps in the data or making it difficult for segments to match. Good data depends on the strength of the device's GPS signal and can also be affected by an obscured view of the sky. Letting the device sit for a minute or two to acquire a strong GPS signal before recording can help record better data.

Alternatively, you can also watch the instructions in the video below:
  • What is considered bringing your own (BYO) bag?
    Switching from using disposable bags to using recycle bags helps with saving carbon emissions because it reduces the consumption of a disposable plastic or paper bag. Custos intention is to reward individuals who brings their own bags to replace the consumption of a disposable bag when carrying newly purchased items. As such, Custos currently only rewards individuals who display the use of a non-disposable bags for purpose of carrying newly purchased items.
