Individual donations are the primary source of funding for most environmental NGOs, as they are typically small organizations with limited resources.

Corporate sponsorships are not a common method of resource mobilization for environmental NGOs, as many NGOs are reluctant to accept funding from corporations due to potential conflicts of interest.

Unreliable donor funding is the main challenge faced by environmental NGOs, as they often rely on short-term grants and donations, which can make it difficult to plan and implement long-term projects.

Environmental NGOs can increase their financial sustainability by diversifying their funding sources, building strong relationships with donors, and investing in fundraising capacity.

Technology can help environmental NGOs reach a wider audience, facilitate online fundraising, and track their progress and impact.

Crowdfunding is not a reliable source of funding for environmental NGOs, as it is often difficult to predict how much money a campaign will raise.

Capacity building can help environmental NGOs develop the skills and knowledge needed to raise funds, build strong relationships with donors, and track their progress and impact.

Advocacy can help environmental NGOs raise awareness for environmental issues, build relationships with policymakers, and secure government funding.

Transparency and accountability can help environmental NGOs build trust with donors, attract more funding, and comply with legal and ethical requirements.
