What defines an "eco-friendly funeral"?

An eco-friendly funeral is characterized by practices that minimize environmental impact. This definition incorporates a range of sustainable practices aimed at reducing waste and carbon footprint associated with traditional burial and cremation methods. Eco-friendly funerals often include the use of biodegradable materials, natural burial sites, and energy-efficient processes, ensuring that the funeral aligns with an environmentally conscious ethos.

Options that suggest funerals held outdoors, the use of traditional caskets, or high-cost ceremonies do not inherently promote environmental sustainability. Outdoor services can be part of an eco-friendly funeral, but they aren't a defining factor. Additionally, traditional caskets often made from non-biodegradable materials do not align with eco-friendly practices. High-cost ceremonies might indicate more lavish options that could lead to greater resource use and waste, which contrasts with the principles of an environmentally friendly approach. Hence, the correct answer emphasizes practices specifically designed to reduce ecological impact.
