Key Details
The OECD brief, Bridging the Silos to Tackle Climate Change, Biodiversity Loss and Pollution, examines national climate and biodiversity reporting and planning documents. Its central finding concerns what those plans address, not a ranking of countries’ environmental performance.
Scope: The stocktake covers 10 countries, including India, and examines 20 national documents, with supplementary climate reporting material where a first Biennial Transparency Report was unavailable.
Recognised link: The documents discuss how climate change affects biodiversity relatively extensively.
Missing link: They pay much less attention to how climate change or biodiversity loss can affect pollution.
Policy gap: Plans frequently identify measures that benefit more than one environmental goal, but seldom set out how to anticipate and manage trade-offs.
India example: The brief cites urban greening as a measure that can increase carbon sinks and improve air quality. It does not evaluate the nationwide results of India’s urban-greening initiatives.
Pollution Receives Less Attention Than Climate–Nature Links
The OECD finds that the countries’ plans generally recognise that climate change can damage ecosystems. Their treatment of pollution is less developed, particularly where changing climate or ecosystems may alter pollution levels. This matters because planning separately for each problem can miss effects that cross administrative boundaries or policy portfolios.
For India and Uganda, the OECD consulted National Communications to the UN climate convention as supplementary material because their first Biennial Transparency Reports were not available when the stocktake was conducted in 2025. The exercise therefore offers a qualitative view of planning, not a uniform measure of implementation across all 10 countries.
A Green Measure Can Also Create an Environmental Cost
Urban greening illustrates the potential for shared benefits: vegetation can help store carbon and improve air quality. But benefits are not automatic across every intervention. The OECD uses renewable energy as a counterexample: expanding it can cut emissions and air pollution, while placing pressure on habitats and creating end-of-life waste from equipment.
The issue is not whether to pursue clean energy or nature-based measures. It is whether their location, design and waste implications are considered early enough to avoid shifting an environmental burden elsewhere.
Existing Planning Tools Could Connect the Three Goals
The brief proposes fuller treatment of pollution and trade-offs in national climate and biodiversity documents. It also points to coordination across ministries, sectoral plans, environmental assessments and budgets that track related objectives together.
Policy Relevance
India’s urban-greening example shows why joined-up planning can be useful, but it is only one illustration in a cross-country review. The more consequential question for Indian policy is whether climate and biodiversity plans — and the assessments used for individual projects — identify pollution effects and environmental trade-offs before decisions are made.
That is particularly relevant where renewable-energy infrastructure, urban development or restoration projects involve choices about land, habitats, materials and waste. The OECD brief does not establish that India has failed to manage a particular trade-off; it identifies a planning gap across the documents it reviewed and a practical reason to examine such effects together.
