Opportunity Green

Climate Solutions

Opportunity Green mitigates climate change by using legal, economic and policy initiatives aimed at reducing emissions in line with a 1.5C pathway by 2050.

Addressing climate change

What problem is Opportunity Green working on?

Opportunity Green (OG) focuses on high-impact areas where climate efforts have stalled or been overlooked – particularly in sectors such as aviation, shipping, steel, and agriculture. OG’s team of lawyers, economists, scientists, diplomacy and advocacy specialists bring innovative, multidisciplinary solutions that drive systemic change and prioritise climate justice in these hard-to-decarbonise sectors.

What does Opportunity Green do?

Opportunity Green is a climate NGO that fills the gaps others miss – holding polluters to account and pushing solutions in sectors like shipping and aviation, where significant impact can be made but which are often overlooked.

  1. OG pushes for accountability and integrity in climate governance. They hold governments, corporations and financiers accountable for their climate responsibilities.
  2. OG champions a just, inclusive and transparent climate transition. They work with climate vulnerable countries and marginalised groups to strengthen their voices in global decision-making.
  3. OG builds strategic partnerships to accelerate systemic change. They work across sectors with industry first-movers and leaders doing things right to develop ambitious, high-impact strategies that influence policy decisions.

In the past 4 years Opportunity Green has

  • Launched a major legal challenge against the European Commission, requesting it to review its green investment rules on aviation and shipping.
  • Increased the participation of a variety of ambitious climate vulnerable countries in the International Maritime Organization to advocate for climate solutions
  • Established the Skies and Seas Hydrogen-fuels Accelerator (SASHA) Coalition which brings together frontrunner, ambitious aviation and shipping companies to ensure that limited green hydrogen and direct air capture resources go to sectors that have no real alternatives

Been recommended as one of Giving Green’s Top Recommendations for impactful climate giving in 2023, 2024 and 2025.

Please note that GWWC does not evaluate individual charities. Our recommendations are based on the research of third-party, impact-focused charity evaluators our research team has found to be particularly well-suited to help donors do the most good per dollar, according to their recent evaluator investigations. Our other supported programs are those that align with our charitable purpose — they are working on a high-impact problem and take a reasonably promising approach (based on publicly-available information).

At Giving What We Can, we focus on the effectiveness of an organisation's work -- what the organisation is actually doing and whether their programs are making a big difference. Some others in the charity recommendation space focus instead on the ratio of admin costs to program spending, part of what we’ve termed the “overhead myth.” See why overhead isn’t the full story and learn more about our approach to charity evaluation.
