New Research Reveals Major Benefits of Integrated Approaches to Climate and Nature

Using new data and novel analytical approaches, research released this week by the UN Environment Programme (UNEP) and partners underscores the size of the prize on offer from integrating action to save nature and combat climate change.

The report, Strengthening synergies: How action to achieve post-2020 global biodiversity conservation targets can contribute to mitigating climate change, finds that conserving 30 per cent of land in strategic locations could safeguard 500 gigatonnes of carbon stored in vegetation and soils – around half the world’s vulnerable terrestrial carbon stocks – and reduce the extinction risk of nearly 9 out of 10 threatened terrestrial species.

Launched today at an event convened by the UN-REDD Programme as part of the UN Framework Convention on Climate Change’s (UNFCCCRace to Zero Dialogues – specifically on nature’s pivotal role in the fight against the climate crisis – the report shows that coordinating priority areas to conserve both biodiversity and carbon stocks is key to meeting ambitious goals for both nature and climate. It highlights areas where global conservation action can deliver the most to achieve biodiversity goals and mitigate climate change. Co-authored by the UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) and a number of supporting partners, the research shows that when prioritizing areas for conservation, accounting for biodiversity and carbon together can secure 95 per cent of the biodiversity benefits and nearly 80 per cent of the carbon stocks that could be obtained by prioritizing either value alone.

The authors highlight the fundamental interconnectedness of the climate change and biodiversity loss crises, and make the point that more integrated approaches are needed to address them. Actions that capitalize on the contributions of nature, known as nature-based solutions, and are based on inclusive decision-making that recognizes the land rights of indigenous peoples and local communities, are especially crucial to acting effectively to address climate change and biodiversity loss.

“There is no climate solution without the full contribution from nature. As the UNEP-WCMC report and the work of UN-REDD show, if we are able to realize the full contribution of nature to climate change mitigation, we will have also achieved the goal of biodiversity conservation,” said Inger Andersen, Executive Director of UNEP.

The analysis identifies well-known biodiversity hotspots as the most important regions to priorities for nature-based climate solutions – these include: Brazil’s Atlantic Forest, Mesoamerica and large parts of Mediterranean biomes and South-East Asia, as well as other hotspots on the West African Coast, Papua New Guinea and the East Australian Rainforest. Other areas important because of the vast amounts of carbon they contain include the lowlands south of the Hudson Bay, the Amazon rainforest and the Congo Basin.

Lord Zac Goldsmith, the UK Government Minister for Pacific and the Environment, said: “November marks one year to go until the COP26 climate summit in Glasgow, and as co-hosts, we are in a strong position to galvanize global action. This important research underlines the critically important connections between climate and biodiversity and the urgent need to protect nature. In September the Prime Minister committed to protect 30% of our land by 2030 as we work to build back better and greener from the coronavirus pandemic. This builds on our campaign through the Global Ocean Alliance to protect 30% of the world’s ocean by 2030. We are encouraging all countries to increase their efforts to protect and restore nature as a solution not only to climate change, but biodiversity loss and poverty too.”

Andrea Meza Murillo, Minister for Environment and Energy of Costa Rica said: "We are still in the turmoil of the tragedy and disruption of Covid-19, and scientists tell us that we only have a window of 10 years to solve the climate crisis and to reverse the severe trend of biodiversity loss. If we work together and we protect at least 30% of the planet by 2030, we will be on a clear pathway to meet the twin goals of climate change mitigation and biodiversity conservation. The road towards COP26 is critical to address this crisis”.

Sveinung Rotevatn, Minister for Climate and the Environment of Norway said: “The world is facing several crises at the same time. We must halt the loss of biodiversity and reduce emissions of greenhouse gases. Bringing tropical deforestation to zero will contribute to both. Norway partners with tropical forest countries to reduce deforestation and forest degradation. Norway is making high-resolution satellite data freely available to forest country governments and the public. The rules are in place. Now is the time for private companies to be clear they will tackle deforestation in their supply chains and pay for emissions reductions from tropical forest countries that deliver high quality, certified results guaranteeing social and environmental integrity. Only by coordinating their efforts and aggregating their demand for emissions reductions will they truly help tropical forest countries drive down deforestation.”

“Climate change and biodiversity loss are twin crises that should be tackled together, with ambition and integrated action. This analysis highlights locations across the world where conserving land can best help to both keep carbon stocks safely stored away and boost protection for threatened species,” said Valerie Kapos, one of the report’s authors and the head of Climate Change and Biodiversity at UNEP-WCMC.

The findings underscore that greater ambition and action are needed to bend the curve of biodiversity loss and greenhouse gas emissions. As global progress is driven by national action, applying the analytical approaches used in this study to inform national scale decision-making will be key; this report supports the case for national climate targets (Nationally Determined Contributions) to incorporate ambitious policies for conserving and restoring nature.

November marks one year to go until the UN Climate Change Summit (COP26), which will be hosted in Glasgow next year by the UK in partnership with Italy. On December 12, 2020, the UK, United Nations and France will co-host the Climate Ambition Summit alongside partners Italy and Chile, on the fifth anniversary of the landmark Paris Agreement. The findings of the report are expected to contribute to the growing body of knowledge on biodiversity and climate ahead of the start of the UN Decade on Ecosystem Restoration and the UN Decade of Action on the Sustainable Development Goals (2021-2030).
