Opportunity Green: Top Climate Nonprofit Spotlight
.png)
Giving Green classifies Opportunity Green as one of our top nonprofits for addressing climate change. We have recommended Opportunity Green since 2023.
Reducing emissions from aviation and maritime shipping is challenging due to the lack of commercially available alternatives to fossil fuel propulsion, as well as barriers to international coordination. Greening these sectors has been historically overlooked by philanthropic efforts. Opportunity Green leverages industry coalitions, direct advocacy, and legal frameworks to create more favorable policy, financial systems, and markets for low-carbon technologies. The organization focuses on solutions with a substantial climate mitigation impact, while seeking avenues that also deliver environmental justice co-benefits.
We think Opportunity Green is a strategic organization with broad expertise across multiple pathways of influence to reduce emissions from aviation and shipping. We have seen signs of its influence across the private sector, the EU, and the International Maritime Organization (IMO). We are especially excited about Opportunity Green’s efforts to elevate climate-vulnerable countries in international policy discussions, as we think such efforts could improve the inclusivity and the ambition levels of these processes.
Opportunity Green is a young organization and could benefit from additional funding to build staffing capacity across its aviation and shipping programs in preparation for upcoming EU and IMO policy windows. It would also develop emerging workstreams in high-impact areas such as addressing emissions from steel manufacturing, data centers, and agriculture.

What Is Opportunity Green?
Opportunity Green is a U.K.-based nonprofit organization using legal, policy, and economic frameworks to advance climate action. It primarily focuses on reducing emissions from aviation and maritime shipping.
How Could Opportunity Green Help Address Climate Change?
Opportunity Green’s focus is to reduce emissions from aviation and maritime shipping. It achieves this by influencing international and EU regulations, as well as by stimulating climate action within the private sector. Its advocacy efforts focus on accelerating the commercialization of low-carbon fleets and fuels, as well as reducing contrail emissions from aviation.
What Does Opportunity Green Do?
Opportunity Green’s approach to reducing aviation and maritime shipping emissions incorporates four main strategies:
- Supporting contributions from climate-vulnerable countries in international policy discussions.
- Advocating for ambitious policies and regulations in the EU.
- Identifying and pursuing strategic legal action to influence policy, financial institutions, and industry.
- Facilitating a private-sector coalition to promote clean alternative fuels.
What's New in 2025?
In 2025, Opportunity Green grew its staff capacity from 21 to 29 members. Key activities include opening an office in Brussels to strengthen its EU-level policy advocacy, launching a major legal filing against the EU to challenge its green finance rules, and supporting climate-vulnerable countries through negotiations surrounding the IMO’s new global shipping levy.
What Would Opportunity Green Do with Your Donation?
With additional funding, Opportunity Green would increase staff capacity across its aviation and shipping programs. Alongside its ongoing work to strengthen international climate diplomacy, Opportunity Green would prepare for upcoming policy opportunities in the EU, including discussions to expand the EU Emissions Trading Scheme, regulate contrail emissions, and influence the Irish EU presidency. Opportunity Green is also developing emerging workstreams in new areas such as addressing emissions from steel manufacturing, data centers, and agriculture.
Why Is Giving Green Excited About Opportunity Green?
We think Opportunity Green’s interdisciplinary expertise fills valuable gaps in the nonprofit advocacy ecosystem for the hard-to-abate aviation and maritime shipping sectors, which have historically been overlooked. We think Opportunity Green has a compelling and impactful theory of change that leverages multiple pathways of influence, including coalition and capacity building, policy advocacy, and legal action.
