More on the News

• World Environment Day 2026 highlights the growing climate crisis reflected in record temperatures, extreme weather events, melting glaciers, rising sea levels, and ecosystem degradation. 

• The United Nations Environment Programme (UNEP) has launched the #NowForClimate campaign, urging governments, businesses, cities, and citizens to accelerate climate action. 

• The campaign stresses the need to rapidly reduce greenhouse gas emissions, scale up renewable energy, conserve forests and oceans, and strengthen climate resilience. 

About World Environment Day

• It was established by the United Nations General Assembly in 1972 following the United Nations Conference on the Human Environment and was first celebrated in 1973 under the slogan “Only One Earth.” 

• It is observed annually on 5 June and is led by the United Nations Environment Programme. 

• It has become the world's largest environmental public outreach platform, engaging millions of people across more than 150 countries. 

• The observance serves as a global platform to raise awareness and mobilize action on issues such as climate change, pollution, biodiversity loss, deforestation, land degradation, and sustainable consumption. 

• Each year, a host country leads the global celebrations and promotes a specific theme to inspire environmental action worldwide. 

• In 2026, Azerbaijan hosts the global commemoration in Baku, with events and campaigns taking place across the world. 

India's Climate Action and NDC (2031–35)

• The Union Cabinet has approved India's enhanced NDC for 2031–35 under the Paris Agreement, aligned with the vision of Viksit Bharat and the goal of achieving Net Zero by 2070.

• India achieved its earlier NDC targets ahead of schedule, including a 33–35% reduction in emissions intensity of GDP and a 40% share of non-fossil fuel-based installed power capacity.

• The country has now set targets of 47% reduction in emissions intensity, 60% non-fossil fuel-based installed power capacity, and a 3.5–4.0 billion tonnes CO₂-equivalent carbon sink through forest and tree cover by 2035.

• India's climate action is driven by initiatives such as LiFE, National Green Hydrogen Mission, PM Surya Ghar, PM-KUSUM, ISA, CDRI, and the Global Biofuel Alliance.

• The strategy emphasizes clean energy, climate resilience, ecosystem restoration, sustainable development, and climate justice, while balancing economic growth with environmental protection.

Significance

• Promotes Global Climate Action: Highlights the urgent need to limit global warming to close to 1.5°C by reducing greenhouse gas emissions, accelerating renewable energy adoption, and strengthening climate commitments worldwide. 

• Supports International Environmental Cooperation: Serves as a global platform for governments, international organizations, businesses, and civil society to collaborate on environmental solutions and advance commitments under the Paris Agreement and Nationally Determined Contributions (NDCs). 

• Encourages Sustainable Development: Promotes sustainable consumption, resource efficiency, clean energy, and nature-based solutions while emphasizing the link between environmental protection, food security, water security, public health, and economic resilience. 

• Strengthens Conservation Efforts: Draws attention to the protection and restoration of forests, oceans, biodiversity, and other ecosystems that function as vital carbon sinks and maintain ecological balance. 

• Highlights Emerging Environmental Challenges: Raises awareness about climate tipping points, warming oceans, Arctic ice loss, deforestation, biodiversity decline, plastic pollution, and the increasing frequency and intensity of extreme weather events.
